High performance textiles mechanism

High performance polymer fibers (HPPF) have excellent mechanical properties compared to traditional textile fibers such as nylon. The typical HPPFs are aramid and polyethylene fibers (6). Aramid is a generic name for a class of aromatic polyamide fibers, most of which are varieties of poly(p-pheny-lene terephthalamide). Kevlar is the trade name of the varieties of aramid polymers introduced conunercially by Dupont. The molecules in the fibers of these materials are oriented in the axial direction. Poly(p-phenylene terephthalamide) is a rigid molecule with the following structure ...

Different types of protective clothing need to withstand attack from specific environmental hazards and thus require the constituent textile materials to have high performance in specific properties. For example, a body armour system requires the textile materials used to have superior mechanical properties firefighters clothing requires its component materials to have exceptional fire resistance properties and chemical protective clothing requires the materials to be resistant to the attacks of chemical agents. 

A considerable number of microcapsules intended for textile applications are fabricated using melamine-formaldehyde resin. The reason for this is its superior performance, including high hardness and mechanical robustness, excellent heat resistance, water resistance, outdoor weatherability, and unlimited colorability (Fei et al., 2015). Properties of polymer wall material should be carefully considered when opting for the best embedding method and choice of a compatible binder. Salaiin et al. (2009) investigated the adhesive properties of microcapsule wall material, melamine... 

Fibers and yams and threads are typically in the order of micrometer or millimeter. This could be compared with triad layers in the realm of nanometer to 10 of nanometer. Textile processes like yam spinning, embroidery, etc. for sure make different textiles come together, but this is due to mechanical-physical means, not chemical. Triads are the basis for transistors, the heart of high-performance computation. We caimot expect the same level of efficiency quality for any textile device mimicking the triad of state-of-the art electronics. 

Protech (protective textiles) These products can offer protection against extreme cold, radiation, harmful particulate matter, harmful chemicals, extreme heat and/or fire, molten metals, bacterial and viral contamination, ballistic and mechanical threats, etc., where high-performance fibers are often used. The current size of the personal protective clothing and equipment market in the European Union is estimated to be about 10billion. Advances in novel specialty fibers, nanoparticles, and the integration of microelectronic components into fabrics and garments have opened up new frontiers in the development of textile-based materials for personal protection.
