Influence of Chitosan Characteristics in the Microencapsulation of Essential Oils

The fight against nosocomial infections in hospitals, has promoted the use of microencapsulated essential oils on medical wearing uniforms. These types of microcapsules can be improved with the use of antimicrobial polymers in the shell structure. Chitosan is one of the most used biopolymers and the effectiveness of the treatment can be increased with the combination of different molecular weight chains of chitosan. This modification in the composition of shell structure allows controlling the rate of hydrolysis and, therefore the amount of its cationic form. The main objective of this work is to define a methodology to get microcapsules with different shell compositions, using surfactants as stabilizers in their first step. Once they have been obtained, these microcapsules will be fixed into textile substrates with the objective to use these tissues as surgical and medical clothes to spread the antibacterial effect, in sanitary staff, as well as in the own patient. In the process of microencapsulation the molecular weight distribution of polymers, influences strongly the delivery mechanisms of the active principle, as well as the chemical characteristics of the textile substrate used in every case. In this work, several chitosan biopolymers have been checked. Structural changes in the stabilization first step and the influence of the cross-linking extension have been related with the final antibacterial effect when fixed on cotton substrates.

Functionalization of medical textiles

An important basis for the creation of medical clothing is realization of the influence of various factors that arise in the interaction of elements of the system "man–clothes–production environment". Given the increasing technogenic burden on health of both medical staff and hospital patients, the assessment of the role of medical clothing in forming the energy balance of direct consumers is extremely relevant.
 Previous studies have experimentally confirmed the presence of energy effects of textile materials on the human body. However, determination of the nature of the impact is a complex task, which solution depends on a number of factors, such as the raw material composition, its structure, surface characteristics, etc.
 The purpose of our paper is to study the development of textile multifunctional materials for medical purposes and to study their energy-information impact on the human body. The following tasks have been solved in the course of the study. For use in the medical field, several samples of textile materials with antimicrobial properties, modified by herbal preparations, were obtained. Properties of textile materials that determine the possibility of their use in medical practice have been investigated. The influence of the experimental samples on the functional state of the organs and systems of human organs by use of the methods of information-wave therapy is evaluated.

Влияние неравновесной низкотемпературной плазмы на потребительские характеристики спанмелт-материала

Nonwovens (nonwovens) are widely used in medicine, for the manufacture of medical linen, sanitary and hygienic items, medical clothing, surgical materials (including dressings). The rapid development of the clothing market requires domestic manufacturers to be competitive not only through new products and technologies, but also new sensations for the consumer, provided that the price is competitive. According to medical workers, disposable surgical gowns based on spunmelt materials give a feeling of discomfort during use. One and relatively new method for modifying nanomaterials is treatment with nonequilibrium low-temperature plasma (NLTP). The main advantage of this type of material modification is the environmental friendliness of the method, as in the process of processing aqueous solutions of chemicals are not used, as in the case of using special impregnations. Modern research of medical services. As a result of the work, it was revealed that the modification of NM NNTP allows you to change the NM for changes in surface, physical and mechanical, as well as consumer properties, while maintaining the strength characteristics. It is shown that after plasma treatment spunmelt materials increase such consumer characteristics as air permeability, hygroscopicity, while maintaining the strength during elongation; reduction of material stiffness during bending. It was also found that after the processing of NTPP, the electrification rate increases within the normal range, in GOST 12.1.045-84. Manufacturers are recommended to process spunmelt material with non-equilibrium low-temperature plasma on a high-frequency capacitive plasma installation with a power of Wp = 1.5 kW, processing time τ = 180 s and pressure P = 21.5 Pa. Use argon gas with a gas flow of 1500 cm3/min as a plasma-forming gas.

Comparison of Textile Resistive Humidity Sensors Made by Sputtering, Printing and Embroidery Techniques

This paper presents various constructions of flexible textile humidity resistive sensor prototypes which can be used in textronic clothing applications and can be easily integrated with fabric. They can be also used as sensors applied to sheets in hospitals and nursing homes, as well as in special medical clothing, especially for protecting elderly people. The author describes a method of manufacturing such sensors by three different techniques, such as embroidery, printing and sputtering (PVD). Also presented are electrical properties of the textile sensors under various environmental conditions. The resistance of the sensors was studied in a wide range of humidity, from 30 to 90%, and at temperatures of 30 °C and 40 °C. The author then chose the right type of textile substrate on which the sensors should be made. A microscopic examination of the upper electroconductive layer of the prototype sensors was also conducted. These novel methods of sensor creation for humidity measurement on flexible textile substrates and their comparison could be used for clothing functionalisation.

EMI Shielding of the Hydrophobic, Flexible, Lightweight Carbonless Nano-Plate Composites.

The cost-effective spray coated composite was successfully synthesis and characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and X-ray diffraction techniques. The one step synthetic strategy was used for the synthesis of nanoplates that have a crystalline nature. The composites are amorphous and hydrophobic with micron thickness (<400 μm). The maximum contact angle showed by composite is 132.65° and have wetting energy of −49.32 mN m−1, spreading coefficient −122.12 mN m−1, and work of adhesion 23.48 mN m−1. The minimum thickness of synthesized nanoplate is 3 nm while the maximum sheet resistance, resistivity, and electrical conductivity of the composites are 11.890 ohm sq−1, 0.4399 Ω.cm−1, and 8.967 S.cm−1, respectively. The cobalt nanoplate coated non-woven carbon fabric (CoFC) possesses excellent sheet resistance, hydrophobic nature, and EMI shielding efficiency of 99.99964%. The composite can block above 99.9913% of incident radiation (X band). Hence, the composite can be utilized in application areas such as medical clothes, mobile phones, automobiles, aerospace, and military equipment.

Medical Nonwovens: Effects of Radiation Sterilization on Bursting Strength

The production of nonwovens over the past few years remains one of the most promising areas in the textile industry. This is due to the short cycle of production of such materials from raw materials to finished products and the ability to produce at a low cost a wide range of materials for both household and technical use. In particular, non-woven materials are widely used for the manufacture of disposable medical clothing and underwear. An important characteristic for surgical clothing is an indicator of bursting strength. This study simulates material deformation similar to elbow pressure when bending the arms or knee when bending the legs. Since the lower part of the sleeve of the product refers to the critical zone of the product, i.e. to the zone most likely to be involved in the transfer of infectious pathogens to or from the wound, the sterile product must have a significant margin of bursting strength. The effect of the absorbed dose of electronic radiation on the strength during the bursting strength of nonwoven medical material of SMS design with a surface density of 35 and 50 g/m2 obtained using the spanmelt technology was studied. It is shown that electronic radiation significantly reduces the resistance of the nonwoven to bursting strength. With an absorbed dose of 40 kGy, the material no longer meets the requirements for surgical clothing and linen by regulatory documents. For non-woven materials obtained using spanmelt technology, the bursting strength rate is even more sensitive to the action of ionizing radiation than the tensile tensile load, therefore, this indicator is recommended to be used as a characteristic indicator of radiation resistance.

Molecular Characterization and Survival of Carbapenem-Resistant Acinetobacter baumannii Isolated from Hospitalized Patients in Mostar, Bosnia and Herzegovina.

Increasingly difficult treatment of multidrug-resistant (MDR) bacteria has become a global problem of the 21st century. Within a group of multiresistant bacteria, the Acinetobacter baumannii convincingly occupies the position at the top of the group designated as ESKAPE pathogens. In this study, 61 isolates of A. baumannii were recovered from different samples originating from various departments of the University Clinical Hospital Mostar during 2018. All of the isolates were identified using conventional phenotypic methods and the VITEK® 2 Compact System, and were confirmed by MALDI-TOF mass spectrometry. The minimum inhibitory concentrations (MICs) were determined by the microbroth dilution method using MICRONAUT-S MDR MRGN-Screening and VITEK 2 Compact System. All strains were resistant to carbapenems and classified in eight different resistotypes according to their antibiotic resistance and macrorestriction pulsed-field gel electrophoresis profiles, with all belonging to IC II. One isolate displayed resistance to colistin (MIC ≥16 mg/L). The presence of blaOXA genes encoding OXA-type carbapenemases was investigated by multiplex PCR and the Eazyplex® SuperBugAcineto system and showed 100% compatibility with the detection of acquired oxacillinases. Molecular characterization of the isolates tested in this study revealed the OXA-23- and OXA-40-like groups of acquired oxacillinases. Sequencing of two PCR products of the OXA-40-like group confirmed the presence of OXA-72. Survival assays with two selected isolates of A. baumannii encoding different mechanisms of carbapenem resistance revealed that one isolate was able to survive on a fragment of white laboratory coat during 90 days of monitoring. To the best of our knowledge, this is the first article to present the results of a comprehensive phenotypic, genotypic, and molecular analysis of A. baumannii isolates from the leading clinical hospital center in the southwestern part of Bosnia and Herzegovina, including data for the survival of this pathogen on the white laboratory coats used as compulsory medical clothing.

The effect of the type of protective suit on the thermophysiological comfort of surgeons in an operating room

Surgical gowns and medical clothing have to protect the surgeons from the patient and vice versa. However, all players in the operating room (OR) have to be in a state of thermophysiological comfort. The comfort of the surgeons is of special importance, as they are exposed to stressful situations, which could influence their performance negatively. The study presents an analysis of the thermophysiological comfort of the surgeons in an OR, using protective clothing ensembles with different clothing insulation and protection: a surgical scrub suit (SSS) and a clean air suite (CAS). The analysis is based on the calculation of PMV-PPD indexes, following Fanger’s model. Different combinations of thermal environment parameters and clothing insulation are tested and analysed.

The Effect of Radiation Sterilization on the Stress-Strain Properties of Non-Woven Materials -Based on Polypropylene

Non-woven materials are widely used for the manufacture of disposable medical clothing and underwear. Radiation is widely used to sterilize single-use medical devices. The paper analyzes the effect of ionizing radiation at absorbed doses of 0-60 kGy on the stress-strain properties of medical non-woven spanmelt material based on polypropylene obtained by blow-molding technology. It has been established that ionizing radiation significantly reduces the breaking load and elongation in the machine and cross directions of the web. For this type of material, the most critical is the decrease in strength in the cross direction of the web, primarily because the level of strength in the cross direction of spanmelt materials is generally low. Sterilization by ionizing radiation further reduces strength and leads to the fact that non-woven materials irradiated with an absorbed dose of 50-60 kGy are close to unacceptable values in accordance with the requirements of EN 13975-2011.

Fiber Structure, Tensile Behavior and Antibacterial Activity of Polylactide/Poly(butylene terephthalate) Bicomponent Fibers Produced by High-Speed Melt-Spinning

Various types of bicomponent fibers composed of polylactide (PLA) and poly(butylene terephthalate) (PBT) with different molecular weights, arranging the polymers separately in the skin or core, were produced by high-speed melt-spinning. The bicomponent spinning, arranging the PLA with high molecular weight (melt flow rate =1.9 g/10 min, L-lactide content = 98.7%) in the skin and the PBT with low molecular weight (IV = 0.835–0.865 dL/g) in the core, resulted in orientation-induced crystallization in the PLA component at the spinning speed of 2 km/min. This crystallization effect was ascribed to a chain-extending treatment applied to the original PLA (MFR = 4.0 g/10 min) to increase its molecular weight. By the treatment the PLA could crystallize when spun even at 1 km/min in its single-component spinning. On the other hand, the bicomponent spinning system interfered with the orientation-induced crystallization of PBT in the core. As a result, the critical spinning speed needed to generate the orientation-induced crystallization in the core PBT was elevated to 4 km/min. The inferior tensile behavior of the bicomponent fibers, as compared to the single-component PLA or PBT fibers, suggested poor compatibility between PLA and PBT. Transesterification reactions rarely occurred at the interface of the two polymers. The bicomponent fibers prepared from high molecular weight PLA and low molecular weight PBT, however, showed sufficient antibacterial activity and physical properties to be suitable for designing medical clothing materials.

Antibacterial effects of barium titanate reinforced polyvinyl-siloxane scaffolds

Polyvinyl-siloxane (PVS) is a modified condensation silicon that has found applications in the field of dental impression materials thanks to its high biocompatibility and the ability to be modeled on solid surfaces with a micrometric resolution. Major concerns have been raised on the possibility to sterilize PVS without distorting its geometrical shape, as immersion in antibacterial solutions often results in swelling. As a possible alternative, both radiofrequency glow discharge and UV sterilization have been successfully applied. In this paper, we focus on the possible use of a cheap, bio-compatible ceramic reinforcement powder (BaTiO3) to obtain a higher resistance to colonization and contribute to the prevention of bacterial infections, not only for temporary applications but also long-term. We also use a vacuum treatment to transform the composite polymer into soft scaffolds with relative densities between 35 and 65%) with similar biological properties. Testing with fractions of ceramic reinforcement up to 25% has clearly shown a beneficial effect in terms of bacteria viability against Staphylococcus epidermidis, with potential for future applications as soft biomedical scaffolds, medical clothing, sanitary materials, and filters for the sterilization of air and water.

Properties and mechanism of antistatic biodegradable polylactic acid/multi-walled carbon nanotube composites

In this study, antistatic biodegradable polylactic acid (PLA)/multi-walled carbon nanotube (PLA/MWCNT) composites were prepared by the melt-blending of MWCNT with PLA. The conductive, mechanical, thermal properties and microstructure of the PLA/MWCNT composites were investigated. Results revealed that with the loading of 1.0 to 1.5 wt% of MWCNT, the tensile strength, elongation at break, and crystallinity of the composites slightly increase, followed by a downward trend with the further increase in the loading amount of MWCNT. With the increase in the MWCNT loading amount to 3.0%, the volume resistivity and surface resistivity of the composites were reduced by nine orders of magnitude. According to the internal microstructure of PLA/MWCNT, by the loading of 1.5 wt% of MWCNT, the MWCNT formed a conductive network in the composite matrix, reaching the percolation threshold. The new composties can be applicated in medical protective clothing for protecting the electronic instrument.

PATHOPHYSIOLOGICAL ASPECTS OF COMPRESSION THERAPY USE FOR PREVENTION OF SCARS AFTER BURNS

Mechanical squeezing of a skin cover by knitted clothes or its details is considered as the basic technological principle of compressive therapy. The definition of a level of squeezing the body by medical pressure clothes and manufacturing of an individual pattern for it sewing is offered to be carried out on the basis of physiologically adequate criteria of blood microcirculating of patients with various anthropometrical and functional blood pressure parameters with the help of the device - electronic tension-meter. Ischemization of the connective tissue parts of the scar, which is clinically confirmed by the foliation of the skin under compression elastic clothing, leads to a decrease in the mass of connective tissue and accelerated subsidence of the processes of inflammation and maturation of scar tissue. At the same time, the object affected by the compression therapy is the connective tissue that is formed, keeping the collagen fibers and fibroblasts in disorder. Creating a compression in excess of 25 mm Hg per cm2 in the early stages leads to a reduction in interstitial edema and limitation of excess formation of granulation tissue capillaries. According to the results of experimental and preliminary clinical studies, it was found that the optimum mechanical compression of the body tissues with elastic clothing is achieved by mechanical compression, which in quantitative terms corresponds to half of the average dynamic blood pressure, adjusted to the level of development of subcutaneous adipose tissue of the patient. In addition to the anatomical and physiological features of the structure of subcutaneous adipose tissue in different parts of the body, according to the results of clinical observations in people with different levels of vascular tone, it became necessary to take into account not only the average dynamic but also diastolic pressure, that largely determines the conditions of transcapillary blood exchange, resulting in additional compression of their outer compression clothing that can not only affect the level of local blood flow, but also the ability of hemodynamic function. While wearing medical clothing for compression therapy, the patient subjectively felt compression of the tissues, and objectively this was accompanied by mechanical pressure on the pressure sensor, and therefore – by switching on a light indicator, which indicated the achievement of the necessary mechanical impact on the compression therapy of the tissue. Thus, the suggested method provides a technological and accurate removal of the pattern of clothing for compression therapy, which will help to produce the optimal clothing size, and therefore to achieve the desired therapeutic effect.

Functional Design of Supportive Men’s Underwear with a Microbial Barrier

A functional modelling of supportive clothing is proposed in this paper. Body forms and measures were analysed. The digitisation of the human body was performed by 3D scanning, and based on point clouds measurements were taken. and the forms of body parts for which the pattern of clothing was developed, were defined. Pattern parts of the male supportive underwear model proposed were translated into numeric form, and a program was developed in the C++ programming language through which the pattern parts are adjusted to individual measurements and to the material used for the compression of parts of the body. Since clothing can be used post-operatively as well, an analysis of the biodegradable Tencel® materials proposed to be used for these applications was conducted. Material samples were subjected to steam sterilisation at 134oC, after which tests of microbial barrier permeability were performed using the new method. Aerobic bacterial endospores were used. Based on the samples tested and their properties, the construction of supportive medical clothing which, by their design, enhance the functionality and possibility of preventing infections of a body part subjected to surgery was carried out.

High-Speed Melt Spinning of Polylactide/Poly(Butyleneterephthalate) Bicomponent Fibers: Mechanism of Fiber Structure Development and Dyeing Behavior

Bicomponent fibers consisting of polylactide (PLA) as the sheath and poly(butylene terephthalate) (PBT) as the core were produced by high-speed spinning to obtain materials suitable for medical clothing. The higher-order structure of the PLA fiber component appeared to exhibit simple, alternately stacked, uniaxially oriented amorphous and crystalline regions. Therefore, fairly large tanδ peaks were observed for single-component PLA fibers, even when the orientation-induced crystallization was achieved by high-speed spinning. By conjugating PLA with PBT, although limited mutual interference with the crystallization of each component occurred, both the PLA (Mw = 170,000, L-lactide content = 98.7%) and PBT (intrinsic viscosity = 0.835-0.865 dL/g) could crystallize on a high-speed spinning line, and the proposed formation of a shish-kebab-like structure in the PBT component enhanced the thermal stability of the bicomponent fibers, particularly resulting in shrink-proof properties. The bicomponent fibers developed herein could be deeply dyed at 98 °C, with results comparable to those of industrial polyester, and peeling of the PLA skin layer was rarely observed, even when the dyed fibers were flattened by a rubbing force.

Design and application of a patient's clothing for critical ultrasound examination

At present, most of the common medical clothes in clinic are uniform medical clothes, but there is no special clothes for patients in intensive care unit (ICU). In recent years, with the extensive application of critical ultrasound in the field of critical medicine, it is obviously difficult to meet the clinical needs on traditional patients' clothes. Guangdong Provincial People's Hospital designed a patient's clothing for critical ultrasound examination. The left/right chest, lateral chest, groin and abdomen of the patient's clothing body were covered with cloth and marked areas. When critically ill patients need to be examined by ultrasound and electrocardiogram, the site can be quickly located only by removing the cloth. At the same time, it can protect patients' privacy, avoid aggravating the condition due to cold, increase patients' comfort in clothing, and also facilitate medical care. It is worthy popularizing in clinic because of its practicability and novel design.

Highly fluorinated chemicals in functional textiles can be replaced by re-evaluating liquid repellency and end-user requirements

Ongoing regulation of, and concerns regarding, per- and polyfluoroalkyl substances (also popularly known as “highly fluorinated chemicals”), has driven the textile market to search for sustainable alternative chemistries that can provide similar liquid repellency to per- and polyfluoroalkyl substances in performance textiles. This paper aims to inform the potential substitution of fluorochemicals with more environmentally friendly durable water repellents, taking a case-by-case approach and evaluating protection needs for consumer outdoor clothing and medical protective clothing separately. Recently developed non-fluorinated durable water repellents, some based on green chemistry principles, were evaluated in an in-depth assessment for their functionality against fluorinated short-chain alternatives (with hydro-and oleophobic moieties of carbon chain length of six or less). Repellency towards water and non-polar liquids was evaluated with established standard test methods and by measuring the roll-off angle of liquid droplets with a novel sample holder setup. This improved method allowed an enhanced mechanistic understanding of the droplets’ roll-off processes on woven textiles. The best non-fluorinated alternatives demonstrated high water repellency equal to fluorinated side-chain polymers with 'short' fluorinated carbon chains ≤6 carbons, and should be considered as suitable substitutes for consumer outdoor clothing. These results are supported by a survey of end-use requirements indicating water repellency and durability were the most important purchasing criteria. For polar liquids, with lower surface tensions, the repellency provided by non-fluorinated alternatives was clearly reduced, although they had a moderate repellency towards liquids with intermediate polarity (e.g. red wine or synthetic blood). Only fluorinated side-chain polymers with 'short' fluorinated carbon chains ≤6 carbons were seen to provide sufficient protection to polar liquids with very low surface tension (olive oil or gastric fluid). Since occupational protective clothing (e.g. medical clothing) often must provide protection against liquid of a wider range of polarities (e.g. in the case of medical clothing, to bodily fluids and protect the wearer from the transmission of diseases), current non-fluorinated DWRs do not provide sufficient liquid repellency. This implies that innovations in textile technology are still needed to substitute PFASs in some types of occupational protective clothing and other end uses where oil and stain repellency is essential.

Optimization of Plasma Bioregulatory Effects in Children 5-6 Years Old with Scoliosis against the Background of Daily Wearing of Medical and Preventive Clothing

For children 5-6 years old, scoliosis is characterized by a violation of bioregulatory effects in the blood, which is combined with inhibition of their physical development. In order to eliminate the phenomena of scoliosis and normalize the level of bioregulatory compounds in plasma, the observed children were recommended to wear medical-preventive clothing every day. As a result, six months of its use in observed children with scoliosis was marked by a positive dynamics of the indicators taken into account. Observed children with scoliosis during daily wear during 6 months of the author's version of medical and preventive clothing attained weakening of the curvature of the spine, increasing strength and endurance of the muscles of the trunk, gradual restoration of the balance of bioregulatory substances in the plasma. As a result of the study, it can be argued that the daily wearing during six months of medical and preventive clothing removes scoliotic symptoms in children with scoliosis and leads to a level of normal plasma content of bioregulatory substances.
