Acrylic fiber yog lub npe lag luam ntawm polyacrylonitrile fiber ntau hauv kuv lub tebchaws. Acrylic fiber muaj cov khoom zoo heev thiab hu ua "synthetic wool" vim nws cov khoom nyob ze rau cov ntaub plaub. Txij li thaum muaj kev lag luam hauv xyoo 1950, kev loj hlob tau tiav lawm. Xyoo 1996, lub ntiaj teb tag nrho cov khoom siv acrylic fiber ntau yog 2.52 lab tons, thiab kuv lub teb chaws cov zis yog 297 txhiab tons. Nyob rau hauv lub neej yav tom ntej, kuv lub teb chaws yuav vigorously tsim acrylic fiber ntau lawm. Txawm hais tias acrylic fibers feem ntau hu ua polyacrylonitrile fibers, acrylonitrile (feem ntau hu ua thawj monomer) tsuas yog 9 0}% mus rau 94%, qhov thib ob monomer suav rau 5% mus rau 8%, thiab thib peb monomer yog 0. 3 %-2.0%. Qhov no yog vim hais tias cov fiber ntau ua los ntawm ib tug acrylonitrile polymer tsis yooj yim, yog nkig, thiab yog heev nyuaj rau zas.
Yuav kom kov yeej cov kev tsis txaus ntawm polyacrylonitrile, tib neeg siv txoj kev ntxiv ib lub monomer thib ob los ua cov fiber ntau; ntxiv ib qho thib peb monomer los txhim kho lub peev xwm dyeing. 1. Cov khoom siv raw ntawm acrylic fiber yog pheej yig propylene, uas yog los ntawm cov khoom siv roj av tawg. Thaum cov polyacrylonitrile copolymer yog rhuab saum 230C, nws tsuas decomposes thiab tsis yaj. Yog li ntawd, nws tsis tuaj yeem yaj-spinned zoo li polyester thiab nylon fibers. Siv txoj kev daws spinning. Spinning yuav qhuav los yog ntub. Lub qhuav spinning ceev yog siab, haum rau spinning imitation silk fabrics. Kev sib tw heev yog tsim los ua cov fibers luv luv, fluffy thiab mos, thiab tsim nyog rau kev ua ntaub plaub zoo li ntaub. 2. Kev ua tau zoo thiab kev siv cov acrylic fiber Elasticity: Nws muaj elasticity zoo dua, thib ob tsuas yog polyester, thiab li 2 npaug siab dua li nylon. Nws muaj kev ruaj ntseg zoo. Lub zog: Txawm hais tias lub zog ntawm acrylic fiber tsis zoo li polyester thiab nylon, nws yog 1-2 siab dua ntaub plaub. 5x ua. Thaum tshav kub kub tsis kam: Lub softening kub ntawm fiber ntau yog 190-230C, thib ob tsuas yog polyester nyob rau hauv hluavtaws fibers.
Lub teeb tsis kam: Lub teeb tsis kam ntawm acrylic fiber yog qhov zoo tshaj plaws ntawm tag nrho cov hluavtaws fibers thaum raug cua qhib rau ib xyoos, thiab lub zog tsuas yog txo los ntawm 20%. Acrylic fiber yog resistant rau acids, oxidants thiab cov organic solvents, tab sis tsis alkali. Acrylic tiav cov khoom muaj bulkiness zoo, zoo warmth tuav, mos tes xav, zoo huab cua kuj, mildew thiab npauj kuj. Qhov sov so ntawm acrylic fiber ntau yog li 15% siab dua li cov ntaub plaub. Acrylic fiber ntau tuaj yeem sib xyaw nrog cov ntaub plaub, thiab cov khoom siv feem ntau yog siv rau pej xeem lub hom phiaj, xws li ntaub plaub, pam, knitted sportswear, tarpaulins, curtains, dag fur, plush, thiab lwm yam. Acrylic fiber kuj yog raw khoom rau cov khoom siv high-tech. - carbon fiber ntau.
