Fragrant black silk ribbon (Nomex) fiber is a kind of scent a group of things with common features gets together amine fiber, according to the raw material that its use, can divide it is a Wei Fangguan and counterpoint fragrant black silk ribbon two kinds. Wei Fangguan's element bends easily between, because this regards spin as material aptly, be like high temperature resistant defend take, fire control is taken, military uniform and space suit, itself is the color that suckle 黃. Fragrant black silk ribbon has counterpoint outstanding heat-resisting performance, its machinery stability is very good, can do bulletproof vest. Fragrant black silk ribbon or a kind flame retardant fiber, lol of its limiting oxygen index is worth ≧ 28% , combustion, won't fused in air or generation frit drips, have good dielectric protecties.
However the coloring of fragrant black silk ribbon is relatively difficult, of dye on catch a gender poorer. Latter, china spin Inc. technology center to use new technology to Nomexlil-T455 fragrant black silk ribbon can use accelerate to will use cation dye dye below the condition of 120 ℃ , obtained better result. When catching full treatment, the steam that should choose to be chosen through the sieve cling to Maxilon cation dye, serve as accelerate with benzoic acid, boric acid natrium is swelling agent; When coloring, should join sodium nitrate with aggrandizement the Peng of fragrant black silk ribbon is changed; Coloring time should hold a hour, arrive in order to ensure dye is thorough fiber 內 ministry, but time also cannot too long, coloring time is too long, prison of insolation of Maxilan blue GRL is spent meeting substantially reduce; As a result of the hear resistance of fabric of fragrant black silk ribbon, dimension stability can maintain when condition of prep above standard, mix the dimension stability of yarn fabric to increase fragrant fishing line, should pull below condition of 180 ℃ ×30s finalize the design.
