Single-bath-single-stage enzymatic treatment of denim

Denim has been a popular choice of apparel worldwide, prized for its versatility and long-lasting qualities. Being a core part of fashion trends for ages, a variety of techniques are being introduced in the denim industry to create a diverse and aged look. This research investigates the application of a combination of amylase, cellulase, and laccase at different temperatures on denim to achieve desired aged or faded appearance. The samples from 9 different washing recipes were analyzed properly for tensile strength, seam strength, color changes, back staining, stiffness, and chemical oxygen demand (COD). The results led to the finding of an optimal washing condition. An aged look on denim fabric can be varied by varying washing temperatures and amounts of laccase enzyme. The highest fading of denim garment was obtained when washed at a temperature of 65 °C for 45 min using 1.5 g/L of amylase, 1.5 g/L of cellulase, and 2 g/L of laccase enzyme. This was confirmed by the lowest whiteness index of the pocketing fabric (70.1) with an improved fabric feel as evident from the lowest bending length of 2.254 cm. The enzymatic process was found to be significantly environment-friendly as generated wastewater required almost 4 times less oxygen to degrade than the wastewater from the conventional process. Notably, this temperature selection did not negatively impact the fabric's tensile strength and abrasion resistance, emphasizing the efficiency of enzymatic processes. It further strengthened the position of single-bath-single-stage enzymatic treatment of denim as an alternative to conventional denim washing.

Revolutionizing protective materials: Ultrahigh peak viscosity through MOF-enhanced shear thickening fluid for advanced soft body armor

The incorporation of shear thickening fluid (STF) into aramid fabric has emerged as a compelling strategy to augment the protective attributes of aramid-based soft body armor. The peak viscosity of STF assumes a pivotal role in shaping the efficacy of this enhancement. In this study, we present an innovation in the design and synthesis of an ultrahigh peak viscosity STF using metal-organic framework (MOF)/SiO2 nanoparticles as the core constituents. The remarkable enhancement in peak viscosity of MOFs/SiO2-based STF, taking ZIF-8 as an exemplary MOFs material, is attributed to the pronounced interparticle contact friction facilitated by the rugged surface morphology of the ZIF-8/SiO2 nanoparticles. Therefore, ZIF-8/SiO2-based STF (62.5 wt.%) demonstrates a peak viscosity approximately 3938 times greater than that of conventional SiO2-based STF (62.5 wt.%). This extraordinary STF formulation has been successfully employed in aramid fabric-based soft body armor, resulting in a significantly advancement in protective performance. Compared to Kevlar fabric impregnated with SiO2-based STF (62.5 wt.%), the utilization of ZIF-8/SiO2-based STF (62.5 wt.%) results in substantial and scientifically significant improvements in key mechanical parameters. These include a notable 15.4 % increase in maximum stabbing force, a remarkable 29.5 % augmentation in maximum yarn pull-out force, a 24.3 % boost in maximum yarn tensile strength, and a 204.5 % enhancement in maximum fabric tensile strength. This research underscores the profound impact of synergizing ZIF-8 and SiO2 within the STF matrix, and significantly improves the protective abilities of SiO2-based STF-impregnated Kevlar fabrics, which provides a new route to design STF-impregnated ballistic fabric with high protective performance.

Eco-friendly biopolishing of cotton fabric through wasted sugarcane bagasse-derived enzymes

Enzymatic processing has been a suitable bio-based sustainable application for the textile industry, mitigates the use of harsh chemicals, and minimises environmental impact. Among these enzymes, cellulase enzymes have been extensively used for biopolishing applications. This study introduces an eco-friendly biopolishing of cotton fabric that has been developed by using enzymes extracted from wasted sugarcane bagasse waste in an aqueous medium. Various extraction conditions were explored, and experiments were conducted under diverse time, pH, and temperature settings. The qualitative BUTEXDCE2022C01 testing method was used to assess the biopolishing effects, resulting in a considerable reduction in fabric weight (up to 5.26%) and strength (up to 10.54%). The optimum biopolishing condition was identified to be 1 h at pH 4.8, 55 °C from the fermented solution on day three, indicating the presence of acid cellulase enzyme. The viability of cellulase enzymes has been verified through comparative analysis with commercial samples that had undergone enzyme-biopolishing. Extracted and filtered enzymes exhibited pH stability at room temperature and proved equally effective as industrial enzymes. As textile industries pursue eco-friendly solutions, extracting cellulase from wasted sugarcane bagasse could be a sustainable and alternative option, which also can be sourced locally. Therefore, these findings have wider implications for sustainable enzyme extraction methods and contributions to environmental conservation.

The influence of polysiloxane on the mechanical properties and water repellency of cotton fabrics

Cotton fabric is commonly used in the textile industry owing to good ventilation and absorption capacity. However, dirt resistance and water resistance of cotton fabrics are low. Therefore, coating cotton fabrics with water-repellent polysiloxane is a special requirement for outdoor and protective clothing products. The effects of polysiloxane content on the water resistance and mechanical properties of materials were studied. The morphology of coated cotton fabric was characterised by SEM (Scanning electron microscope), and EDX (Energy dispersive X-ray) was used to determine the presence of polysiloxane on the surface of cotton fabric. The effects of polysiloxane content on the water resistance and mechanical properties of materials were studied. Compared with raw cotton fabrics, the tensile strength of the cotton fabrics impregnated with 20%wt polysiloxane solution increased, but the elongation at break was reduced. The hydrostatic pressure (AATCC 127) and water spray test (AATCC 22) results showed that the water repellence of polysiloxane-coated cotton fabrics increased significantly compared to pure cotton fabrics. In addition, the polysiloxane content has no almost effect on the water repellency of the material. Therefore, the appropriate use of polysiloxane can contribute to minimising the cost of the product.

Protective Topical Dual-Sided Nanofibrous Hemostatic Dressing Using Mussel and Silk Proteins with Multifunctionality of Hemostasis and Anti-Bacterial Infiltration.

Topical hemostatic agents are preferred for application to sensitive bleeding sites because of their immediate locoregional effects with less tissue damage. However, the majority of commercial hemostatic agents fail to provide stable tissue adhesion to bleeding wounds or act as physical barriers against contaminants. Hence, it has become necessary to investigate biologically favorable materials that can be applied and left within the body post-surgery. In this study, a dual-sided nanofibrous dressing for topical hemostasis is electrospun using a combination of two protein materials: bioengineered mussel adhesive protein (MAP) and silk fibroin (SF). The wound-adhesive inner layer is fabricated using dihydroxyphenylalanine (DOPA)-containing MAP, which promotes blood clotting by aggregation of hemocytes and activation of platelets. The anti-adhesive outer layer is composed of alcohol-treated hydrophobic SF, which has excellent spinnability and mechanical strength for fabrication. Because both proteins are fully biodegradable in vivo and biocompatible, the dressing would be suitable to be left in the body. Through in vivo evaluation using a rat liver damage model, significantly reduced clotting time and blood loss are confirmed, successfully demonstrating that the proposed dual-sided nanofibrous dressing has the right properties and characteristics as a topical hemostatic agent having dual functionality of hemostasis and physical protection.

Effect of secondary material resources on quality indicators of fabric fabrics

In this article 100% cotton fiber waste, 70% rogoza plant fiber waste 30% cotton fiber waste bedding, 50% rogose plant fiber waste 50% cotton fiber waste bedding, 30% rogose plant fiber waste 70 % Air permeability, longitudinal and transverse penetration, hygroscopicity and dye strength of upholstery fabrics obtained from a mixture of cotton fiber waste were determined, and the optimal variant of secondary material resources in the production of upholstery fabric was recommended.

Folding endurance of continuous silicon carbide fibres: A comparative study

The limited folding resistance of continuous silicon carbide (SiC) fibres hinders their application as flexible, foldable materials. With this objective in mind, the folding endurance and damage properties of the second (2nd) and third (3rd) generation continuous SiC fibre tows were investigated through repeated folding tests, optical microscope observation and tensile tests. These SiC fibre tows were disassembled from two-dimensional (2D) SiC fibre braided fabrics with varying braiding angles. The braiding process can alleviate the force on fibre tows during the textile forming process. The investigation of damage mechanisms and analysis of force conditions are instrumental in optimizing structural parameters. The research findings suggested that, in comparison to the 3rd generation continuous SiC fibres, the 2nd generation SiC fibre tows demonstrated higher resistance to repeated folding. In contrast, the 2nd generation fabrics exhibited slightly lower folding endurance values. After repeated folding, the SiC fibre tows in fabrics showed the highest strength losses near the braiding angle of 37.8? to 38.3?. In comparison, the SiC fibre fabric demonstrated the lowest folding endurance values (approximately 760 times) near the braiding angle of 41? to 42?. Considering factors such as folding endurance value, the strength loss rate of fibre tows and fabric strength loss rate, it can be concluded that SiC fibres in fabrics with large braiding angles exhibit optimal performance in terms of folding endurance.

Low temperature reactive dyeing of silk: An investigation into dyeing conditions, and strength loss and friction damage of fabric

The low temperature dyeing of textiles has obvious energy-saving effect. Silk fabric suffers from friction damage in the rope dyeing process, and additionally silk is complained about unsatisfactory color fastness. To address the aforementioned issues, the reactive dyeing of silk fabric at low temperatures was studied in terms of dyeing conditions, dye selection, alkali resistance of silk, and strength loss and friction damageoffabric. Reactive dyes exhibited higher fixation to silk in alkaline bath than acidic and neutral baths. The breaking strength and whiteness of silk fabric was less affected by sodium bicarbonate, but greatly affected by sodium carbonate. Silk fabric treated with sodium carbonate at 50–60 ℃ had acceptable loss of breaking strength (<10 %). Silk fabric dyed at 60–80 ℃ using sodium bicarbonate exhibited higher color depth than that dyed at 50–60 ℃ using sodium carbonate. The high temperature dyeing in alkaline bath caused the friction damage and fuzz appearance of silk fabric, which did not occur in low temperature and alkaline conditions. The reactive dyes selected from commercial products could be applied at 50 ℃ and met requirements for high fixation, high color fastness and a variety of colors.

Preparation of Temperature-Sensitive Colour-Changing Materials and Their Applications to Clothing Fabrics: Taking a Compound Composed of Crystal Violet Lactone, Bisphenol A, and Octadecanol as an Example

A compound was prepared using crystal violet lactone, bisphenol A, and octadecanol. An in-situ polymerization method was used to prepare temperature-sensitive colour-changing microcapsules. It was printed on fabrics using printing technology. The colour-changing performance of the composite material, thermal weight changes of the microcapsules, and properties of the fabric coated with microcapsules were analyzed using cases. Printed fabric properties of colour fastness to washing, rubbing, strength and colour strength (K/S) were measured in terms of binder (%), a crosslinking agent (%), and temperature variations. The results indicated that the compound gradually changed from purple to blue within the temperature range of 3 °C to 60 °C and eventually faded into a colourless state. The weight of the microcapsule powder decreased as the temperature rose, with no significant change in weight before reaching 100 °C. Between 100 °C and 200 °C, there was a rapid decrease in weight, followed by a slow decrease between 200 °C and 350 °C. After reaching 350 °C, the weight tended to stabilize. When the mass fraction of the cross-linker was 3%, the mass fraction of the binder was 25%, and the baking temperature was 120 °C, the colour fastness, fabric strength, and K/S value (colour intensity) of the cotton fabric coated with microcapsules were optimal.

Impact of vitamin E in improving comfort, moisture management and mechanical properties of flame-retardant treated cotton fabric

The aim of this study is to analyze the use of vitamin E to enhance fabric's hand feel, moisture management and fabric strength which are affected due to flame retardant finish. Flame retardant treated fabrics typically become stiff, but the addition of Vitamin E along with emulsifier and binding agent through a vertical padding mangle by two times dipping and nipping results a soft fabric without impairing the flammability properties as determined by 45-degree flammability test. The samples were characterized by FTIR spectra, SEM images, and water contact angle. A new characteristics band is appeared at 1455 cm−1 for skeletal vibration of phenyl ring system of alpha tocopherol for Vitamin E measured by Fourier transform infrared spectroscopy (FTIR) that proves the effective attachment of vitamin E with fabric. Hydrophilicity of vitamin E containing sample is discovered after showing 37.629° as a water contact angle at optical tensiometer (Attension theta lite). Additionally, fabric comfort properties, moisture management properties, and mechanical properties were measured by fabric touch tester (FTT), moisture management tester (MMT) machine and tensile strength tester respectively that demonstrate significant affirmative change in almost all indexes of FTT, 43.5 % increase of overall moisture management capacity by MMT and 23 % increase of tear strength by tensile strength tester due to use of vitamin E that effectively compensate lower strength, poor fabric comfort, and low moisture management capability of flame retardant treated fabric.

Heterostructured MXene/alginate coating for fire warning and protection: Preparation and characterization

Cotton fabrics with intelligent fire warning and protection have promising applications in smart wearables and smart home decoration. In this study, multifunctional nanoparticles (M@A) with heterogeneous structures are constructed through the electrostatic self-assembly of core-shell structured silver nanowires (AgNW@BP) and MXene nanosheets. Subsequently, M@A is blended with bio-based sodium alginate (SA) to prepare multifunctional cotton fabrics that exhibit fire warning, thermal conductivity, high strength, and flame retardancy. For instance, the tensile strength of the multifunctional fabric is 58.5 MPa, surpassing that of some MXene paper/films used for fire warning (~10 MPa). Furthermore, the catalytic charring effect of AgNW@BP and the labyrinth effect of MXene synergistically enhances the flame retardancy of the multifunctional cotton fabric (total heat release rate, total smoke production and peak heat release rate of the multifunctional cotton fabric are 5.7 MJ/m, 0.09 m2, and 126.8 kW/m2, respectively). Significantly, the multifunctional cotton fabric also demonstrates a fast response time (2 s) and repeatable alarm capability when exposed to flames attack.. Hence, this work provides inspiration for the design and fabrication of multifunctional cotton fabrics with intelligent fire warning and protection.

Fabric controls on fracture surface roughness of an architected rock material

Fluid flow through fractures is intimately linked to the fracture surfaces that define the void geometry through which fluids flow. Thus, an understanding of what controls fracture surface roughness is essential to the development of models for predicting fluid transport through fractured rock. The difficulty in predicting surface roughness arises from the complexity of rock which is inherently heterogeneous and nonuniform in composition, fabric, and structural components, even when samples are acquired from the same rock mass. Here, a benchmarked-simulation approach motivated from geo-architected 3D printed synthetic gypsum rocks is used to provide insight into the competing contributions from fabric and layering on fracture roughness formation. Simulation results from a discrete element model (Particle Flow Code, Itasca Consulting Group, Inc.) clearly indicate that the relative orientation between mineral layers and in-layer mineral fabric, and the variability in mineral bonding strengths determine whether anisotropic corrugated surfaces or isotropic surfaces are formed. Weak mineral layers oriented perpendicular to the applied load resulted in strong roughness anisotropy. Peak failure loads were found to vary up to 30% depending on the strength of the mineral fabric at the location of fracture initiation, which provides insight into the observed high variability in strength values of natural rock. The uniqueness of induced fracture roughness and peak failure load is intimately linked to layering, mineral fabric, and their distribution in the rock. These findings have important implications for any architected material fabricated through serial printing of layers with local compositional heterogeneity.

Enhanced safety and strength of cotton fabrics through a novel ‘H-shaped’ multiple flame retardant elements agent

In response to the new concept of green sustainability, it is necessary to expand the functionality of bio-based natural fibers (such as cotton fabrics) to replace fabrics made from fossil fuels. One potential way of achieving this is through the use of phosphorus, boron and nitrogen based organic flame retardants. This article designs a special flame retardant system with high efficiency, high durability, and enhanced fabric strength. An “H” shaped flame retardant (TBSA) is synthesized using hydroxyethyl methylene phosphate, pentaerythritol diborate, and cyanuric chloride. After simple treatment, flame retardant fabric (TBSA/Cotton) is obtained, with a LOI value of 48.8 %. Self extinguishing is completing in the vertical flame test. The high FR efficiency reflects the progressiveness of multi flame retardant elements. It is worth noting that TBSA/Cotton exhibits excellent durability and improves the strength of the fabric. This is attributed to the covalent bonding between the “H” type flame retardant and multiple cellulose molecules, which compensates for the cracks and holes at the submicroscopic scale of natural cellulose and weakens the molecular slip effect. The research results of this article provide a good opportunity for the development of biomass cellulose flame retardant materials.

Variation in olivine crystal-fabrics and their seismic anisotropies in the Horoman Peridotite Complex, Hokkaido, Japan

We examined the microstructures and crystal-fabrics of peridotites within a large area (6×5km) of the Horoman Peridotite Complex in the Hidaka metamorphic belt of Hokkaido, Japan. Thirteen peridotite samples were analyzed for olivine and orthopyroxene grain sizes, fabric strength (J-index), and crystallographic preferred orientations (CPOs). Mean grain sizes of olivine and orthopyroxene were ranged in 295–497µm and in 257–537µm, respectively. The olivine fabric strength values decreased from the lower to the upper part of the complex, whereas the orthopyroxene fabric strength values showed no systematic trends. The peridotites contained three different olivine CPOs, previously known as A, E, and AG types. Combined with a previous study, we found that olivine CPOs showed a transitional distribution from E to A to AG type from south to north. E type peridotites occur at the basement of the complex in the south, suggesting that local water infiltration might occur at the basement of the complex. The A type peridotites occurred mainly in the middle of the studied area and subsequently the AG type peridotites occurred towards the north. Moreover, we calculated the seismic properties of peridotite as olivine 100% aggregates and mixed (olivine and orthopyroxene) aggregates. It showed that orthopyroxene CPOs reduce P-wave anisotropies of peridotite (0.2–2.2%) without modification of the P-wave propagation patterns.

Investigating Tear Strength in Sustainable Cotton-Lyocell Blend Siro Spun Fabrics: Twist Multiplier and Weave Type Effects

This study investigates the tear strength properties of a cotton-Lyocell blend siro spun fabric. Lyocell fibre production follows sustainable practices with a closed-loop system and renewable resources, requiring less energy and water. Furthermore, Lyocell is a biodegradable fibre, ensuring its environmentally friendly decomposition. Similarly, cotton offers durability, washability and biodegradability, making it an eco-conscious fabric alternative. Woven fabrics were created using cotton-Lyocell blend siro spun yarns with varying twist multipliers and thread densities in plain, twill and satin weaves. The tear strength of these fabrics was measured and regression analysis was conducted to investigate the impact of different parameters. The results demonstrate that twist multiplier, warp density and weft density significantly affect the tear strength of all fabric types. Furthermore, a comparison was made between the tear strength of the cotton-Lyocell siro spun fabrics and conventional ring-spun cotton fabrics and found that cotton-lyocell siro spun fabrics offer better strength properties compared to conventional ring-spun cotton fabrics. The findings of this study provide valuable insights into fabric strength factors, contributing to future research in textile development for enhanced durability and sustainability.

Optimisation of laser fading process in denim trousers: An industrial scale approach

AbstractColour fading with laser application has now become a well‐known and frequently used process in the denim industry. However, in practice, high strength losses and even tears may occur in the trousers as a result of incorrect or excessive laser application. In this study, the effects of resolution (dpi) and pixel time (μs), which are the two main parameters of laser colour fading, and also the effects of two‐passage laser treatments on colour fading and fabric strength were examined statistically and optimum conditions were determined. When the results of the studies are evaluated in general, it can be said that as the resolution (dpi) increases during the laser process, the colour fading effect increases, but when it is above the 31 dpi value, the strength loss increases excessively. As the second important parameter, the pixel time, increased, the colour fading effect increased. When the time exceeds 80 μs, there is a marginal increase in the strength loss value. Furthermore, it was observed that colour fading (%) values increase if laser process is applied in two passages, but in this case also the tear strength loss increases. It can be said that optimising the laser processing conditions in enterprises according to the product type (fibre content, weight, etc.) is a more accurate approach in terms of both the fading performance to be obtained and product quality. For 11.25 ounce trousers made of 95.3% cotton/3.4% polyester (T400)/1.3% elastane used in this study, it can be said that laser application could be made in two passages if necessary for obtaining high colour fading, however it should be noted that resolution and pixel time should not exceed 31 dpi and 80 μs, respectively. Provided that resolution and pixel time does not exceed 31 dpi and 80 μs, respectively, they can be changed depending on the degree of colour fading needed.

Bridging the Gap Between Experimental and Natural Fabrics: Modeling Ice Stream Fabric Evolution and its Comparison With Ice‐Core Data

AbstractFabrics, also known as textures or crystallographic preferred orientations, reveal information about the deformation history of the flow of polycrystalline materials, including glacial ice, olivine in the mantle, and feldspar and quartz in the crust. Ice fabrics can have an order‐of‐magnitude effect on the ease of flow in ice sheets. However, due to the choice of ice core drill site locations, the outputs of fabric models have mostly been compared to observations from the least dynamic regions of the ice sheet (ice divides). Recently, fabric data from an active ice stream have become available from ice cores drilled at the East Greenland Ice‐core Project (EGRIP). In this work, we present a novel approach that combines satellite‐derived velocity data with the fabric evolution model SpecCAF, a continuum model based on dominant dislocation creep. We directly compare model output to ice‐core observations from EGRIP, allowing us to examine the quantitative predictions of calibrated fabric models alongside those of active ice streams for the first time. As the model is calibrated against laboratory experiments, it provides a surrogate to compare the evolution of fabrics under laboratory and natural conditions. The predictions show good qualitative agreement with the observed fabric patterns and orientations, suggesting that a fabric between a girdle and horizontal maximum, orientated perpendicular to the flow direction, is the characteristic ice stream fabric. A discrepancy in fabric strength is attributed to the lower strain rates of ice sheets compared to laboratory experiments, revealing a significant strain‐rate dependence in the processes controlling fabric evolution.

Research on the Thermal Insulation Properties of Three-Dimensional Spacer Jacquard Fabric Treated with Silica Aerogel.

Three-dimensional (3D) spacer fabric has the characteristics of a light weight and high strength, and its unique three-dimensional structure gives it great potential for development in terms of insulation. For the purpose of further improving the thermal insulation performance of 3D spacer fabric, the fabric was treated with silica aerogel while solving the problem of powdering during use. Firstly, the electronic Jacquard machine was modified for weaving spacer fabrics. The ground warp yarns were controlled by two groups of heald frames with various positions of heald eye, forming a double-shuttle. The longitudinal warp yarns were controlled by the Jacquard healdwine to prepare a spacer Jacquard fabric with a spacing of 5 mm. Secondly, polyurethane foam was applied as a carrier to compound with silica aerogel. The experimental results demonstrate that the strength of the composite fabrics is significantly increased, while the toughness is decreased. With the increase in silica aerogel content, the pore size of foam becomes smaller, and the degree of foam fragmentation increases, showing a trend of increasing thermal insulation performance followed by a decreasing insulation performance. When the aerogel content is 3.3%, the composite fabric has the optimal thermal insulation performance.

Dyeing Tencel Fabric with Azadirachta Indica Leaves and Mordanting with Potassium Aluminium Sulphate and Citrus Limon Extract for Enhanced Fastness Properties

Amidst mounting concerns regarding the health and environmental repercussions associated with synthetic agents, there has been a burgeoning interest in the exploration of natural dyes as a safer alternative. Derived from minerals, plants, and animals, these natural dyes have gained substantial traction due to their perceived eco-friendliness and reduced health risks compared to their synthetic counterparts. Notably, our study revealed significant enhancements in fastness properties across all mordanted samples, while those left un-mordanted exhibited notably inferior fastness properties. Among the mordants under investigation, potassium aluminium sulphate demonstrated appreciable stability characteristics, yet Citrus limon extract emerged as an even more effective mordant than potassium aluminium sulphate. The study also delved into evaluating the colour strength properties of the test samples, providing a comprehensive analysis of the Tencel fabric's overall dye performance and adherence to industry standards. In this research, a natural dye was extracted from the leaves of Azadirachta indica which was applied to Tencel fabric, which was then meta-mordanted with potassium aluminium sulfate and Citrus limon extract. The study explored various dyeing parameters, including diverse dye concentrations (7 g), dyeing temperatures (35, 50, and 65 °C) with a precision of ±1 °C, and dyeing durations (40, 55, and 75 minutes). The resulting samples were then subjected to testing against fastness properties, including washing fastness (ISO 106 C06), rubbing fastness (AATCC 8), perspiration fastness (ISO 105 E04) and Colour strength (K/S) of the Tencel fabric. The assessment of fastness properties was carried out using a grey scale.

Manufacturing Scalable Carbon Nanotube-Silicone/Kevlar Fabrics.

Carbon nanotube (CNT) hybrid composites were formed by combining a CNT and silicone elastomer solution with Kevlar yarn, Kevlar fabric, and Kevlar veil materials. The integration of a CNT-silicone matrix with Kevlar yarn and fabric materials produced a composite with moderate electrical and thermal conductivity due to CNT fabric combined with the strength of Kevlar fabric or yarn. In the material synthesis, a notable difficulty was that the CNT-silicone did not bond strongly to the Kevlar. The composites passed the Vertical Flame Test ASTM D6413 and the Forced Air Oven Test NFPA 1971. These hybrid composites can have multiple applications in areas requiring favorable conductivity, strength, and flame and heat resistance. The application areas include firefighter apparel, military equipment, conductive/smart structures, and flexible electronics. The synthesis process used to manufacture CNT-silicone/Kevlar composites yielded composite sheets with an area of 2250 cm2. The process is scalable and customizable for the synthesis of CNT composites with tailored properties. Improvements in the bonding of CNT-silicone to Kevlar are being investigated.
