Dyeing thiab xov txheej txheem ntawm spandex ywj ntaub

Nyob rau hauv xyoo tas los, spandex-muaj cov khaub ncaws ncab tau dhau los ua nrov heev hauv kev lag luam hauv domestic thiab txawv teb chaws thiab tau tsim kho sai heev. Txij li xyoo 1980, nws tau txais kev pom zoo los ntawm cov neeg, tshwj xeeb tshaj yog thaum xyoo 1990. Vim nws lub siab elasticity thiab zoo heev resilience, cov khoom no muag muag rau qhov kov, xis hnav thiab tuaj yeem qhia qhov zoo nkauj ntawm lub cev. Ntxiv rau, nws nqus tawm hws thiab tsis tsim hluav taws xob zoo li qub, yog li nws tau txais ntau dua thiab ntau daim ntawv thov. Tam sim no, nws tau siv dav hauv kev lag luam textile, los ntawm kev txhim kho sab hauv ris tsho hnav mus rau sab nraud, knitted ntaub rau ntaub xov, khaub ncaws ntaub los ua cov ntaub npuag thiab cov ntaub ntawv ua haujlwm, xws li cov ntaub ua lag luam rau kev siv kho mob, nrog kev txhim kho dav thiab tau txais txiaj ntsig zoo ntawm kev lag luam. Cov. Spandex fiber tau thawj zaug tau los ntawm Bayer thiab cov npoj yaig hauv lub teb chaws Yelemees xyoo 1937 siv cov txheej txheem polyisocyanate polyaddition kom tau txais cov khoom lag luam polyurethane elastic fiber ntau. Txawm li cas los xij, kev lag luam loj-loj tau pom los ntawm DuPont hauv Tebchaws Asmeskas xyoo 1962 thiab muab npe hu ua lycra (Leica). Tom qab, Bayer, Nyiv Toray, Toyobo, Zhongyuan, Teijin, Kuraray thiab lwm lub tuam txhab ua tiav ntau yam tshiab. Kaus lim qab teb yog qhov ceev tshaj plaws ntawm spandex hauv xyoo tas los no thiab tau dhau los ua tus tsim khoom lag luam hauv ntiaj teb. Tuam Tshoj qhov kev thov spandex yog tus loj. Thaum xyoo 1990, nws twb muaj hauv Yantai, Shandong, thiab Lianyungang, Jiangsu. Guangdong Heshan, Fujian Changle, Shanghai Qingpu, Zhejiang Shaoxing thiab lwm qhov chaw tau tsim spandex ntau lawm kab nrog kev tsim khoom txhua xyoo muaj peev xwm ntawm 25,000 tons. Nrog rau kev nce siab hauv cov hom thiab ntau thiab tsawg ntawm cov ntawv luam tawv, kev tsim khoom thiab daim ntawv thov ntawm spandex hauv Suav teb yuav raug nthuav dav ntxiv. Raws li daim ntawv tshaj tawm cov ntaub ntawv nyob rau xyoo tas los no, muaj kev lag luam zas thiab ua tiav rau cov tuam txhab thiab cov tsev kawm qib siab ntau dua 10 lub xeev thiab nroog xws li Shanghai, Jiangsu, Zhejiang, Anhui, Shandong, Fujian, Guangdong, Sichuan, Hubei, Hebei, Liaoning, Henan, thiab Shaanxi. Lub tsev kawm ntawv tsim thiab tsim ntau yam ntawm spandex-uas muaj cov khoom siv ntab. Qee qhov ua tiav thiab cov kev paub dhau los tau ua tiav, tab sis kuj tseem muaj qee cov teeb meem uas xav tau kev tshawb fawb ntxiv thiab sib tham, xws li kev tsis sib haum xeeb ntawm qhov loj me ntawm qhov ruaj ntseg ntawm lub qhov rooj dav thiab alkali concentration thiab lub teeb kub. Qhov kev tsis sib haum xeeb ntawm kev siv tshuaj chlorine ua kom dawb thiab ua kom huv si, alkali concentration Kev tsis sib haum nrog de-doping effect thiab huv si ntau lawm, ntau dhau shrinkage tus nqi, kev tsis sib haum ntawm daim ntaub yellowing thiab elastic rov qab tus nqi, thiab daim ntawv thov ntawm cov roj ntsha enzymes. Tam sim no, cov neeg ua haujlwm scientific thiab cov kws ua haujlwm hauv kev lag luam dyeing thiab xov tau tshawb pom cov xwm txheej zoo tshaj plaws rau kev zas thiab xov tooj thev naus laus zis ntawm spandex elastic ntaub, thiab tshawb txog kev sib txheeb ntawm txoj kev dyeing thiab ua tiav thiab cov khoom sib txig ntawm spandex, dim seem thiab npuag dav hloov ntau, thiab spandex dyeing thiab xov. Qhov yuav tsum ua ntawm cov khoom kom tau txais qhov zoo tshaj plaws zas thiab ua tiav. Cov hlua elastic ua tau zoo dua kom tau raws li cov kev hloov pauv ntawm txoj kev ua lag luam. Los ntawm cov xov xwm ntau ntawm cov ntawv luam tawm, tus kws sau ua ke cov kev paub dhau los ntawm txhua qhov kev ntsuas, tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm txhua qhov kev ua haujlwm zas thiab ua tiav, thiab ua ke cov kws sau tawm tswv yim los hais qee cov tswv yim rau kev ua spandex stretch fabrics.
