Zylon has been incorporated as the base fiber for some conductive textiles, where the Zylon fiber is plated with nickel, copper, silver, or gold. The conductive fiber is used for electronic textiles, EMI shielding in woven or knit sheets, or as a braid over wires, and for signal transmission or current conduction.
Polybenzimidazole (PBI, short for poly[2,2’-(m-phenylen)-5,5’-bisbenzimidazole]) fiber is a synthetic fiber with a very high decomposition temperature. It does not exhibit a melting point, it has exceptional thermal and chemical stability, and it does not readily ignite. [1]
Neutral water at room temp has not been shown in testing to negatively affect the performance of para-aramid or UHMWPE [13] but acidic, basic and some other solutions can permanently reduce para-aramid fiber tensile strength. [14] From 2003 to 2005, a large study of the environmental degradation of Zylon armor was undertaken by the US-NIJ.
The testing of fabrics offers a comprehensive review of the various tests that can be performed on fabrics. [20] Fabric testing includes measurements such as fabric weight , fabric width, shrinkage testing, colour fastness to washing , fastness to light , pilling , tearing and bursting strength, etc.
In 2011, Yantai Tayho introduced similar fiber which is called Taparan in China (see Production). Para-aramids are used in many high-tech applications, such as aerospace and military applications, for "bullet-proof" body armor fabric. Both meta-aramid and para-aramid fiber can be used to make aramid paper.
A number of tests are available to determine a fabric's basic fiber makeup, some of which can be performed prior to purchasing a fabric whose composition is questionable. Tests include rubbing the pile in the hand, burning a small piece of the fringe to smell the ash and smell smoke, and dissolving the pile by performing a chemical test.
Microfiber fabrics are man-made and frequently used for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture (perspiration) away from the body; subsequent evaporation cools the wearer. Microfiber can be used to make tough, very soft fabric for clothing, often used in skirts, jackets, bathrobes, and swimwear.
The polymer is formed by free-radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide (DMF) or aqueous sodium thiocyanate, metering it through a multi-hole spinneret and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated ...
