Chemical zog ntawm polypropylene fiber
Polypropylene fiber ntau yog filament (xws li undeformed filament thiab nthuav deformation ntawm filament), luv fiber ntau, bristles, zaj duab xis split fiber, hollow fiber, profiled fiber, ntau yam fiber ntau puas thiab non-woven fabrics. Nws yog tsuas yog siv los ua cov ntaub pua plag (xws li cov ntaub pua plag hauv qab thiab suede daim ntaub), cov ntaub zoo nkauj, rooj tog ntaub, txhua yam hlua, strips, nuv ntses nets, roj absorbent xav, lub tsev cov ntaub ntawv, cov ntaub ntawv ntim thiab cov ntaub, xws li lim. ntaub, hnab ntaub, thiab lwm yam. Tsis tas li ntawd, nws kuj yog siv dav hauv cov khaub ncaws. Nws tuaj yeem sib xyaw nrog ntau hom fibers rau hauv ntau hom kev sib xyaw ntaub. Tom qab knitting, nws tuaj yeem ua rau hauv lub tsho, tsho tiv no, ncaws pob, thom khwm thiab lwm yam. Lub floc quilt ua los ntawm polypropylene hollow fiber yog lub teeb, sov thiab elastic.
PP hauv cov qauv macromolecular tsis muaj cov tshuaj lom neeg uas tuaj yeem khi rau cov xim, yog li nws nyuaj rau zas. Feem ntau, yaj xim txoj kev yog siv los sib tov cov xim npaj thiab polypropylene polymer tusyees nyob rau hauv ib tug ntsia hlau extruder kom tau txais cov xim ceev ceev ntawm cov xim fibers los ntawm yaj spinning. Lwm txoj kev yog copolymerization los yog graft copolymerization nrog acrylic acid, acrylonitrile, vinyl pyridine thiab lwm yam, thiaj li hais tias cov kev taw qhia ntawm polymer macromolecules yuav tsum tau ua ke nrog cov polar pawg ntawm dyes, thiab ces ncaj qha nrog cov pa txoj kev ntawm dyeing. Nyob rau hauv tus txheej txheem ntawm pp ntau lawm, ntau yam additives yog feem ntau xav tau los txhim kho dyeing, lub teeb kuj thiab nplaim kuj. Lub npe scientific yog polypropylene fiber, nyob ze ntawm cov nplaim taws uas melts, flammable, los ntawm cov hluav taws kub maj mam thiab cov pa luam yeeb dub, daj nplaim nyob rau saum toj, xiav nyob rau hauv qab, emitting roj saj, tom qab hlawv tshauv rau ib puag ncig lub teeb daj xim av hais, tes twist yooj yim tawg. Nws yog tsim los ntawm propylene li raw khoom los ntawm polymerization, yaj spinning fiber.
