A Flexible Sandwich Structure Carbon Fiber Cloth with Resin Coating Composite Improves Electromagnetic Wave Absorption Performance at Low Frequency.

In order to improve the electromagnetic wave absorbing performance of carbon fiber cloth at low frequency and reduce the secondary pollution caused by the shielding mechanism, a flexible sandwich composite was designed by a physical mixing coating process. This was composed of a graphene layer that absorbed waves, a carbon fiber cloth layer that reflected waves, and a graphite layer that absorbed transmitted waves. The influence of the content of graphene was studied by a control variable method on the electromatic and mechanical properties. The structures of defect polarization relaxation and dipole polarization relaxation of graphene, the interfacial polarization and electron polarization of graphite, the conductive network formed in the carbon fiber cloth, and the interfacial polarization of each part, combined together to improve the impedance matching and wave multiple reflections of the material. The study found that the sample with 40% graphene had the most outstanding absorbing performance. The minimum reflection loss value was −18.62 dB, while the frequency was 2.15 GHz and the minimum reflection loss value compared to the sample with no graphene increased 76%. The composites can be mainly applied in the field of flexible electromagnetic protection, such as the preparation of stealth tent, protective covers of electronic boxes, helmet materials for high-speed train drivers, etc.

Effects of Layered Clothing on the Post-mortem Decomposition of Rat Carcasses on Grass Bushes and Dead Leaves

A post-mortem decomposition is defined by the evaluation of the physical and chemical changes of a cadaver or a carcass in order to estimate the cause of death and the time of death. The purpose of this study is not to replicate a real crime scene but to enhance knowledge of the effects of clothing in a decomposition process, mainly, the effects of layered cotton clothing on the post-mortem decomposition of adult female rat carcasses. Fifteen rats were divided into three groups: control, one-layered and two-layered clothed. The control subjects were unclothed and used to compare the post-mortem changes with the clothed subjects, one-layered and two-layered rat carcasses. All subjects were placed outdoor, 2.5 meters away from each other on grass bushes and dead leaves. Ambient temperature and humidity were recorded to observe if it associates with the post-mortem changes of the rats. Insect activity on each subject was observed. Post-mortem changes were measured using the Total Body Score system. The results showed that the control group underwent a faster decomposition compared to the clothed groups. The different layers of clothing did not show a vast difference in post-mortem changes. The ambient temperature of 28°C influences the post-mortem decomposition. The decomposition was rapid under the dominance of maggots compared to ants as ant colonies delayed the decomposition process. The study gave the knowledge of the effect of clothing in decomposition of female rats in forensic science.

Living with Climate Change in Farmworker Communities

Living with Climate Change in Farmworker Communities David Bacon (bio) According to Dr. Jessica Hernandez, a Zapotec scholar and board member of Sustainable Seattle, 'indigenous peoples are the first impacted by climate change'. She points to the fate of the small municipality of San Pablo Tijaltepec, high in the Sierra Mixteca of Oaxaca, in southern Mexico: 'Accelerated changes to our climate due to urbanisation, fossil fuel industry, etc. continues to result in devastating impacts. The heavy rains that have recently taken place in Oaxaca, Mexico, have destroyed many of the harvests Indigenous peoples depend on. For the pueblo San Pablo Tijaltepec, their milpas [corn fields] were completely destroyed. This leaves 800 Mixtec families without the communal harvest they all depend on'. Losing the milpas and harvest is a blow that falls on people already having a hard time surviving. The Mexican government says family income in the municipality averages about $500/month, leaving half its residents in extreme poverty. In 2020 only an eighth of San Pablo Tijaltepec had access to a sewage system, and over a tenth had no electricity. The region's Mixteco-speaking people have been leaving and searching for work for decades as a result, joining the 400,000 who leave Oaxaca for northern Mexico and the U.S. every year. In California's southern San Joaquin Valley, the most productive agricultural region of the world, people from San Pablo Tijaltepec have created a new home, an extension of their Oaxacan community, in the small town of Taft. For over two decades they've worked as farmworkers in the surrounding fields. Here, instead of torrential rains, they face another environmental danger–the summer's heat, which can rise to over 110 degrees in July and August. The connection between climate change and increasing summer temperatures has been dramatised by the 'heat dome' that covered the Pacific Northwest in July, leading to similar temperatures in a region accustomed to lesser heat. Portland had a high of 116 degrees. In the nearby Willamette Valley one farmworker, Sebastian Francisco Perez, died as he continued to work in the heat, moving irrigation pipes, in order to pay a debt to a 'coyote' who'd smuggled him across the border. Scientists, and even President Biden, attributed the heat dome to climate change and its associated drought. In the southern San Joaquin Valley town of Poplar, extreme heat in the summer is the normal condition in which people live and work. It is one of the poorest communities in the state. Air conditioning in trailer homes or crowded houses normally consists of old 'swamp coolers', which hardly lower temperatures. At work people bundle up, using layers of clothing to insulate against heat and dust. Poplar's families are almost all immigrants or their children, who have travelled here from other parts of Mexico, or have crossed the Pacific Ocean from the Philippines. Many now are older people, long accustomed to the heat. Yet for them the danger is greater as they get older. Some already have health conditions springing from poverty and the hard conditions in the fields. 'In extreme heat, the body must work extra hard to maintain a healthy temperature', cautions health journalist Liz Seegert. 'Older adults are at higher risk for heat stroke, heat cramps, heat exhaustion and other serious health issues due to poorer circulation and less effective sweating that comes with aging'. This rural poverty of the southern San Joaquin stands in stark contrast to the enormous wealth the labour of its people produce. Poplar's Tulare County produced $7.2 billion in fruit, nuts and vegetables last year. Yet the average income of a county resident is $17,888 per year, compared to a U.S. average of $28,555, and 123,000 of Tulare's 453,000 residents live below the poverty line. Poverty forced farmworkers to continue working during the pandemic. Tulare County's COVID-19 infection rate was much greater, per capita, than large cities. A year ago Tulare had 7,603 confirmed cases, and 168 deaths. Heavily urban Alameda County had 9,411 confirmed cases and 167 deaths. But Alameda County's population is 1.67 million, over three times that of...

The effect of different structural designs on impact resistance to carbon fiber foam sandwich structures

Abstract The development of the composite materials in the past decades has made the composite materials more and more widely used in various engineering fields. The mechanical properties of the composite materials are gradually improved, especially the impact resistance. In this article, the damage of carbon fiber foam sandwich structure (material grade: W-3021FF/H60) under different sandwich thicknesses and impact energies was studied. Ultrasonic C-scan was used to measure the depth and area of impact damage area. Finally, the impact energy and foam core thickness on impact damage was analyzed by test results. The results show that the impact damage depth and area of foam sandwich structure were positively related to the impact energy, and with the increase in the impact energy, the growth rate of damage depth and damage area changes; the greater the thickness of the foam core was, the stronger the span-direction guiding energy for impact energy, the larger the damage area and the smaller the damage depth. Under the same energy, the more the layers of carbon fiber cloth with the foam sandwich structure, the larger the impact damage depth and the smaller the impact damage area. The proportion of ±45° ply in the foam sandwich structure can improve its impact resistance.

PBNS

We present a methodology to automatically obtain Pose Space Deformation (PSD) basis for rigged garments through deep learning. Classical approaches rely on Physically Based Simulations (PBS) to animate clothes. These are general solutions that, given a sufficiently fine-grained discretization of space and time, can achieve highly realistic results. However, they are computationally expensive and any scene modification prompts the need of re-simulation. Linear Blend Skinning (LBS) with PSD offers a lightweight alternative to PBS, though, it needs huge volumes of data to learn proper PSD. We propose using deep learning, formulated as an implicit PBS, to un-supervisedly learn realistic cloth Pose Space Deformations in a constrained scenario: dressed humans. Furthermore, we show it is possible to train these models in an amount of time comparable to a PBS of a few sequences. To the best of our knowledge, we are the first to propose a neural simulator for cloth. While deep-based approaches in the domain are becoming a trend, these are data-hungry models. Moreover, authors often propose complex formulations to better learn wrinkles from PBS data. Supervised learning leads to physically inconsistent predictions that require collision solving to be used. Also, dependency on PBS data limits the scalability of these solutions, while their formulation hinders its applicability and compatibility. By proposing an unsupervised methodology to learn PSD for LBS models (3D animation standard), we overcome both of these drawbacks. Results obtained show cloth-consistency in the animated garments and meaningful pose-dependant folds and wrinkles. Our solution is extremely efficient, handles multiple layers of cloth, allows unsupervised outfit resizing and can be easily applied to any custom 3D avatar.

Circularly Polarized Wideband Fabric Stealth Multiple-Input Multiple-Output Antenna for Ultrawideband Applications Useful for Wireless Systems Wearable on Garments

Stealth wearable wireless devices are gaining much attention in the personal security and fashion designing industry. A multiple-input multiple-output wideband circularly polarized antenna wearable on a dress (textile-related), which is immune to bending, is described in this paper, where a wearable on fabric dress application uses the MIMO techniques. It consists of two multiple-input multiple-output types of antenna elements: the resonating elements are created resembling a beautiful peacock shape and the ground plane is appropriately designed. A voltage is applied to each antenna element; the ground plane contains a microstrip transmission line-fed and a rectangular upside-down L-shaped (vertically flipped) strip used for circular polarizing. The antenna covers a 3 dB axial-ratio-band-width (ARBW) value of 5.20–7.10 GHz and impedance bandwidth (S11 less than −10 dB) of 03.60–13.0 GHz. The proposed attachable wearable fabric (textile) multiple-input multiple-output wideband antenna exhibits envelope correlation coefficient (ECC) <0.02, diversity gain (DG) >9.96, channel capacity loss (CCL) <0.2 b/s/Hz, total active reflective coefficient (TARC) <−10 dB, mean effective gain (MEG) ratio within ±0.5 dB. There is dual-sense circular polarization in this antenna and high isolation between resonating elements (higher than 18). A specific absorption rate (SAR) of the proposed antenna for human tissues specimen is also discussed for different situations related to the human body. The overall size of the proposed CP textile MIMO antenna is 34 : 5 × 42 × 1 mm3. Because of its clothing layers (textile), practical performance, and miniature size, the designed MIMO antenna may be helpful for wearable on cloths on human body wireless devices and systems. The proposed antenna can be made unrecognizable because of the beautiful peacock design that can easily mix with the designs of fabric (in the fashion dress). The simulated antenna was fabricated with the help of conventional manual fabrication techniques and tested in real-time situations. The edge-to-edge distance amid the MIMO radiating antennas is 14.2 mm, and the achieved isolation is greater than 18 dB after optimization of the proposed antenna.

Measurement Method for the Simultaneous DeterMination of Thermal Resistance and Temperature Gradients in the DeterMination of Thermal Properties of Textile Material Layers.

The thermal properties of most clothing products are still not designed according to engineering science due to the lack of simple and acceptable measuring equipment and methods; the type of thermal insulation material, the number of layers of clothing and their thickness are thus chosen empirically. The novelty of this study was the development of a new measuring device and method for simultaneous measurements in the determination of the thermal resistance in one or more textile material layers, such as in multilayer composite clothing. Temperature gradients of textile material layers are presented, as well as the theoretical principles of operation and practical results. Four materials for the production of protective jackets were selected, from which different combinations of composite clothing were constructed and the thermal parameters were measured with a new method and a new device, both individually for the built-in materials and for the composites. Subsequently, five test jackets with the same arrangement of textile material layers as the previously tested composites were produced, and measurements of important thermal parameters were recorded with a thermal mannequin. The determined temperature gradients and measurement results are presented, and based on these it was determined that the total thermal resistance was not equal to the algebraic sum of the resistances of the individual textile material layers in the horizontal position; it was, however, higher, increasing from 30% to 94% due to small air layers caused by crimping and protruding fibres of yarn in the textile fabrics. The same textile material layers built into clothing in the vertical position allowed the formation of significantly wider air layers that increased the thermal resistance by between 2.5 and 9 times.

Upaya Pencegahan Covid-19 Dengan Pembagian Masker Kepada Masyarakat Lingkar Tambang Batuan di Kelurahan Kalumata Kota Ternate Selatan

The corona virus or Covid-19 has continued to be a public concern since the beginning of 2020. This is because the virus that originated in Wuhan, China, quickly spread throughout the world, including Indonesia, especially North Maluku. With the spread of the virus, the global community is worried and afraid. The government, the private sector and the community have begun to take part in helping others who are experiencing economic downturn during the pandemic. As an effort to participate in handling the prevention of the corona virus, the Faculty of Engineering, Khairun University feels compelled to participate. Participation is carried out in the Community Service (PkM) program. The Covid-19 prevention effort by distributing masks to the community around the rock quarry in Kalumata Village, South Ternate City has been carried out by involving 5 students, non-medical masks consisting of two layers of cloth as many as 150 pieces that can be used repeatedly and can be washed were successfully distributed for free to the public within 2 days. The community feels very helped by this activity, with this activity it is hoped that it can increase public awareness in an effort to break the chain of the spread of Covid-19, namely in an orderly manner and always wear masks when outside the home, besides that the community is expected to always apply a clean and healthy lifestyle by wash your hands often and use hand sanitizer regularly, keep your distance, take vitamins, and obey the advice to stay at home

A three-dimensional thermoregulatory model for predicting human thermophysiological responses in various thermal environments

This study presents a complete virtual three-dimensional (3D) model of human thermophysiological responses by integrating detailed heat dissipation model from human skin to environment through spatially heterogeneous (realistic) clothing into human thermoregulation model by two-way coupling. The model considered various heat and mass transfer mechanisms in air and clothing layers such as conduction, natural convection, forced convection, radiation, and evaporation. The numerical setup of the model was presented and simulated using ANSYS Fluent. The developed model is systematically validated against experimental data obtained from authors of published literatures. To demonstrate the robustness and accuracy of the model, it has been validated for a wide range of ambient temperatures (−10.0 to 45 °C), relative humidity (25–86%), activity levels (0.8–3.5 mets), clothing thermal resistances (0.10–2.95 clo), and evaporative resistances (11.5–800 Pa m2/W) including steady-state and transient exposures. This complete 3D model predicted human thermophysiological responses for a wide range of ambient condition with good accuracy. The average RMSD (root mean square deviation) of predicted core and mean skin temperatures was 0.21 °C (maximum RMSD = 0.33 °C) and 0.56 °C (maximum RMSD = 1.03 °C), compared to average standard deviation in measured data 0.26 °C and 0.58 °C, respectively. The model is also able to predict the local skin temperature with an average RMSD of 0.64 °C. Therefore, this newly developed model can be served as a useful tool in analysing human thermophysiological responses and heat stress for any given thermal environment and clothing setting.

Clothing and the oceanic identity in Melville’s Redburn

Herman Melville’s Redburn approaches the topic of corporeal coding via the outer layer of clothing. Throughout the novel, the young protagonist consciously uses clothing as a means of self-representation and expression, deploying fashion to create and position himself in different contexts; for example, taking pride in his ragged clothes amongst well-dressed ship passengers becomes a form of social protest. But Redburn is also used to comic effect because his choices are often based on incorrect assumptions of propriety, such as his notion of the way a sailor is supposed to dress not matching the onboard reality. The rules of appearance that construct and restrain an identity are paradoxically bolstered at the same time they are broken, which allows Melville the opportunity to explore rebellion alongside the performative aspect of the self as a body constituting both a visible sign and a living vehicle for the mores, beliefs and ideologies that shape a society.

Water Jet Erosion Performance of Carbon Fiber and Glass Fiber Reinforced Polymers.

Complex engineering challenges are revealed in the wind industry; one of them is erosion at the leading edge of wind turbine blades. Water jet erosive wear tests on carbon-fiber reinforced polymer (CFRP) and glass-fiber reinforced polymer (GFRP) were performed in order to determine their resistance at the conditions tested. Vacuum Infusion Process (VIP) was used to obtain the composite materials. Eight layers of bidirectional carbon fabric (0/90°) and nine glass layers of bidirectional glass cloth were used to manufacture the plates. A water injection platform was utilized. The liquid was projected with a pressure of 150 bar on the surface of the specimens through a nozzle. The samples were located at 65 mm from the nozzle at an impact angle of 75°, with an exposure time of 10, 20 and 30 min. SEM and optical microscopy were used to observe the damage on surfaces. A 3D optical profilometer helped to determine the roughness and see the scar profiles. The results showed that the volume loss for glass fiber and carbon fiber were 10 and 19 mm3, respectively. This means that the resistance to water jet erosion in uncoated glass fiber was approximately two times lower than uncoated carbon fiber.

Effects of high heat flux exposures on tensile strength of firefighters' protective clothing

SummaryThe effects of thermal aging on tensile strength of three Kevlar/PBI blends used in the outer shell layer of firefighters' protective clothing were examined using cone calorimeter exposures of 10‐70 kW/m2 for 30‐300 seconds. Lower heat flux exposures of 10‐15 kW/m2 did not result in significant change in the tensile strength of the fabrics, but significant losses of tensile strength were first observed as the heat fluxes increased to 20‐30 kW/m2 for two ripstop fabrics, and 45 kW/m2 for the third fabric. Further decreases in tensile strength were observed with increasing heat flux until there was almost a total loss of original tensile strength following exposure to 70 kW/m2. Decreases in tensile strength were explained by comparing fabric temperature measurements made using an infrared thermometer, key temperatures in thermal gravimetric analysis test results, and the appearance of the three fabrics after the exposures. While duration of exposure had little effect on tensile strength after exposures to 10 kW/m2, tensile strength decreased with duration of exposure for heat fluxes of 20‐40 kW/m2. The effect of duration was greatest for a heat flux of 20 kW/m2. These results indicate that one must consider not only the maximum temperature that the fabric reaches, but the complete temperature‐time trace, including the time at which the fabric remains at the maximum temperature, when examining the effects of thermal aging on tensile strength.

Electromagnetic interference shielding performance and mechanism of Fe/Al modified SiCf/SiC composites

The pyrolysis of two kinds of inorganic salts Fe(NO3)3 and NH4Al(SO4)2 were respectively used to enhance electromagnetic interference (EMI) shielding performance of SiCf/SiC composites via improving electrical conductivity and electromagnetic performance. The results show that after the modification by Fe and Al elements, the EMI shielding effectiveness of SiCf/SiC composites have been significantly increased in the X-band (8.2–12.4 GHz). In particular, the composites with the plain weave cloth layer structure modified by Fe element possess the maximum SET and SEA values of 39.28 dB and 32.36 dB. Compared with the composites reinforced by the twill cloth, the composites with the plain cloth structure exhibit better electromagnetic shielding performance, which can be attributed to the fabric structure difference that the more buckled yarns in the plain weave provide more reflection and absorption channels for electromagnetic waves in the material, and generate more attenuation. The shielding mechanism can be concluded that the superior shielding effect of SiCf/SiC composites is mainly based on the dissipation of electromagnetic waves caused by the multiple reflection and absorption inside the composites.

The History of the Idea of Glued Linen Armour

Many people have heard that ancient warriors wore armour of many layers of linen cloth glued together. Critics emphasize the lack of archaeological or written evidence for this construction; supporters emphasize that their reconstructions resemble armour in ancient art and pass practical tests. Both present the theory as one that first appeared in the 1970s. This article make two contributions to the debate. It shows how sixteenth-century scholars used a peculiar medieval chronicle to understand the linen armour in ancient texts, and how paraphrases and mistranslations of their theory ultimately lie behind the glued linen of today’s experiments, and it places this debate in the world history of fabric armour and the history of armour scholarship. It proposes that theories about the armour in vase paintings and sculptures should be based on archaeological evidence, types of armour documented in other cultures, or a close study of ancient textile technology, not on simply examining artwork and reading ancient texts.

Can blood pressure be measured without undressing patients ?

The guidelines recommend that the technique of measuring arterial blood pressure requires positioning the cuff on a bare arm, without rolled-up sleeve. These recommendations are sometimes difficult to apply in routine practice, as in dialysis centers where the measurement is repeated in fragile patients. In this study, we assess the validity of the blood pressure measurement with a cuff positioned on a bare arm, compared to a cuff positioned on several layers of clothing.&#x0D; A total of 1,224 blood pressure measurements were taken in 51 dialysis patients over a period of one month, 6 measurements per week, i.e. 24 measurements per patient. The patients wore their ordinary clothes suitable for a winter season. Thus, 612 measurements were taken with a cuff on a bare arm, and 612 measurements with a cuff on clothing. The mean systolic pressures were 121.9 and 123.5 mmHg, respectively when the cuff was placed on clothing and bare skin. The mean diastolic pressure was 60.1 and 60.5 mmHg, respectively. The observed difference does not reach the level of statistical significance with respectively p = 0.168 and p = 0.135. The same is true for mean arterial pressure, with 80.6 and 81.5 mmHg respectively (p = 0.142). The difference observed does not justify the undressing of patients for whom this procedure is difficult, uncomfortable or painful.

An experimental study on crack and debonding of intumescent coatings and their effects on temperature development of steel elements

This paper presents the results of an experimental study to investigate failure modes of intumescent coatings and their effects on temperatures attained in steel sections and fire resistance of steel columns. Tests were carried out on unloaded steel plates, unloaded short sections and axially loaded long columns. The loaded column specimens had four different surfaces, stainless steel, untreated carbon steel, sand-blasted carbon steel and carbon steel with one layer of fibre cloth. The failure modes of intumescent coating char included cracks, debonding and detachment. Detachment seemed to have occurred after the fire tests because there was no evidence of a sudden jump in temperature. The cracks varied from fine distributed cracks to large discrete cracks. These intumescent coating failure modes affected not only average temperatures of the steel but also temperature distributions in the steel sections. The average temperatures attained in the unloaded steel sections were lower than those in the loaded steel columns. The temperature differences for the unloaded plate and sections were relatively small, lower than 2.2% and 6.3% respectively, while they were high for the loaded test specimens, 10–20% of the average.

Development of a flexible wearable thermal textile accessory for winter sports

In pursuit of a healthy lifestyle, people are paying more attention to sports activities, even in winter. They are thus seeking high function and maximum comfort to improve their performance. However, cold weather may result in a higher risk of injuries. It is of prime importance to perform warm-up, which can increase body temperature to relieve muscle stiffness and allow improvement of performance. Unfortunately, the traditional approach of wearing multiple thick layers of clothing to keep warm can prevent the easy movement of the body. Therefore, the integration of flexible textile and wearable thermal technology has become a major research initiative in both sports and textile fields. Current attempts by high-tech start-ups and wearable textile enterprises are not able to overcome the hurdle of transforming wearable technology into a fashionable and marketable product. Hence, this paper introduces a design-driven method to develop a flexible wearable thermal textile accessory for winter sports usage. The relationships between thermal textiles, electrical resistance, thermal performance, stretchability, energy consumption, and function stability were evaluated to optimize the thermal textile fabrication. Then, a prototype was produced and its specification was defined. These enable the realization of mass production and provide a blueprint for the future development of wearable textiles.

COVID-19: A systematic evaluation of personal protective equipment (PPE) performance during restraint.

BackgroundRestraint is widely practised within inpatient mental health services and is considered a higher-risk procedure for patients and staff. There is a sparsity of evidence in respect of the efficacy of personal protective equipment (PPE) used during restraint for reducing risk of infection.MethodsA series of choreographed restraint episodes were used to simulate contact contamination in research participants playing the roles of staff members and a patient. For comparison, one episode of simulated recording of physical observations was taken. Ultraviolet (UV) fluorescent material was used to track the simulated contact contamination, with analysis undertaken using established image registration techniques of UV photographs. This was repeated for three separate sets of PPE.ResultsAll three PPE sets showed similar performance in protecting against contamination transfer. For teams not utilising coveralls, this was dependent upon effective cleansing as part of doffing. There were similar patterns of contamination for restraint team members assigned to specific roles, with hands and upper torso appearing to be higher-risk areas. The restraint-related contamination was 23 times higher than that observed for physical observations.DiscussionA second layer of clothing that can be removed showed efficacy in reducing contact contamination. PPE fit to individual is important. Post-restraint cleansing procedures are currently inadequate, with new procedures for face and neck cleansing required. These findings leave scope for staff to potentially improve their appearance when donning PPE and engaging with distressed patients.

Reusable MoS2-Modified Antibacterial Fabrics with Photothermal Disinfection Properties for Repurposing of Personal Protective Masks.

The current pandemic caused by SARS-CoV-2 has seen a widespread use of personal protective equipment, especially face masks. This has created the need to develop better and reusable protective masks with built-in antimicrobial, self-cleaning, and aerosol filtration properties to prevent the transmission of air-borne pathogens such as the coronaviruses. Herein, molybdenum disulfide (MoS2) nanosheets are used to prepare modified polycotton fabrics having excellent antibacterial activity and photothermal properties. Upon sunlight irradiation, the nanosheet-modified fabrics rapidly increased the surface temperature to ∼77 °C, making them ideal for sunlight-mediated self-disinfection. Complete self-disinfection of the nanosheet-modified fabric was achieved within 3 min of irradiation, making the fabrics favorably reusable upon self-disinfection. The nanosheet-modified fabrics maintained the antibacterial efficiency even after 60 washing cycles. Furthermore, the particle filtration efficiency of three-layered surgical masks was found to be significantly improved through incorporation of the MoS2-modified fabric as an additional layer of protective clothing, without compromising the breathability of the masks. The repurposed surgical masks could filter out around 97% of 200 nm particles and 96% of 100 nm particles, thus making them potentially useful for preventing the spread of coronaviruses (120 nm) by trapping them along with antibacterial protection against other airborne pathogens.
