Textiles for Functional Applications

Conventionally, textiles are known to cover up the human skin, but by scientific administration, clothing can be extended to serve other human skins’ functions. Accepting the chemical and dermatological complexity of human skin, the effect of humidity, microbes, pH, temperature, and wind can be engineered by wrapping it by functional clothing. In this regard, the latest class of textile material has been added called functional textiles. Such clothing materials consist of the potential of delivering more than one functionality apart from its primary function to coverups the human body. This present chapter offers state-of-the-art viewpoints on the application of functional textiles, including assorted concerns. First, the skin responds to various environmental stimuli and then overviews various techniques to incorporate functionalities in textiles. Finally, the applications and future scope and possibilities of research in this field are included in this chapter. Miniaturisation to small micro to nanometre scale is registered as one of the most exciting meadows in engineering and science over the past few decades. This drift also grasps colossal potential to functionalise the textiles. Various techniques are available now to develop a thin uniform film of functional materials on clothing surface to offer extra functionalities hitherto unrevealed to textile processors. These technologies are based on layer-by-layer assembling, immobilisation of enzymes on textile surfaces, nanocoating of textile substances, plasma for nanoscale modifications, and loading of various functional biomaterials micro and nanoencapsulation by minimum influence on breathability, feel, handle, and strength. The manufacturing of functional textiles can be classified into two groups. One is to functionalise the fibre by adding dope additives, modifying the fibre forming polymer, and then converting it to clothing. The fibre surface is also functionalised by adding some resins on the fibre surface. The other is to modify the textile surfaces by functional biomaterials, resins, finishes.

“…[ 23,26,27 ] Natural fibers, like cotton, wool and silk, and biobased fibers derived from natural resources, like rayon and lyocell, also have many desirable characteristics, including strength, hydrophilicity, chemical functionality, and inherent biodegradability, [ 28–30 ] which makes them attractive for developing novel functional materials. [ 21,31–36 ] While several approaches to creating heterogeneous textile catalysts by covalent chemical, [ 19,37 ] photochemical [ 38 ] or layer‐by‐layer [ 39 ] reactions between textile fibers and enzymes have been explored, those evaluations focused on immersing or dispersing the catalytic fibers into liquids containing enzyme substrates. Also, although delivering flowing substrate to immobilized enzymes in a microfluidic reactor was developed, [ 40 ] the reactive flow of liquids within structurally self‐supporting biocatalytic textiles as described herein has not been described in any previous study.…”

A robust biocatalytic yarn with controllable liquid transport properties is created by coating thin layers of chitosan containing catalase onto a cellulosic yarn. The resulting material integrates enzyme catalytic functionality with protective coating properties of chitosan and structural functionality of the textile. Mild immobilization conditions and good affinity between the two polysaccharides minimize enzyme inactivation during the preparation steps and prevent enzyme from leaching during peroxide decomposition testing and washing, providing a novel and versatile enzyme immobilization strategy. The catalytic efficiency of enzymes in a reaction containing solid, liquid, and gas phases is facilitated when dissolved enzyme substrate is transported by liquid flowing through the coated textile structure. The flow‐through configuration decomposes at least two times more peroxide in a twenty‐times smaller reaction zone volume compared to a stirred tank configuration. Liquid transport through the yarn and liquid spatial distribution within the yarn are investigated by in situ neutron radiography and neutron computed tomography, revealing a constrained wicking mechanism that benefits biocatalytic yarn performance. This new class of sustainable and flexible biocatalytic textile matrices has beneficial multifunctional properties, not previously described, that are applicable for numerous small‐ and large‐scale applications including controlled flow reactors and reactive filtration.

“…Fibre and textile carriers have recently drawn considerable attention for enzyme immobilization due to their low price, large specific surface area, and ease of fabrication [ 32 ]. To date, common fibres such as cotton [ 33 ], silk [ 34 ], wool [ 28 ], polyester [ 35 , 36 ] and nylon [ [37] , [38] , [39] ] have been employed for enzyme immobilization mostly in non-woven form [ 14 ].…”
