Chidziwitso choyambirira ndi kugwiritsa ntchito polyester staple fiber

Ulusi wokhazikika ukhoza kugawidwa m'magulu osiyanasiyana malinga ndi magawo osiyanasiyana. Malinga ndi zopangira zitha kugawidwa mu ulusi woyambira komanso wosinthikanso. CHIKWANGWANI choyambirira chimapangidwa kuchokera ku PTA ndi ethylene glycol ndi polymerization, kupota ndi kudula, komwe kumadziwika kuti "Large chemical fiber", pambuyo poyanika, kusungunuka, kupota, kudula kumapangidwa, komwe kumadziwika kuti "Chingwe chaching'ono chamankhwala." Zingwe zoyambira zimagawidwa m'magulu osungunuka molunjika ndi kupota kwa batch motsatira njira zosiyanasiyana zopota. Sungunulani ulusi wopota wolunjika umapangidwa kuchokera ku PTA ndi ethylene glycol popota mosadukiza popanda kupanga tchipisi ta poliyesitala. Pakadali pano, ukadaulo wa melt direct spinning umatengedwa popanga mitundu yodziwika bwino ya fiber ku China. Kupota kwa batch, komwe kumadziwikanso kuti chip spinning, ndi njira yopangira ulusi kuchokera ku tchipisi ta PET. Poyerekeza ndi kusungunula molunjika, kupota kwa batch kumachepetsa gawo la poliyesitala, kumawonjezera kuyanika kwa chip ndi kusungunuka, ndipo njira yotsatirayi ndiyofanana. Ulusi wokhazikika umagawidwa m'magulu atatu malinga ndi ntchito zawo zosiyanasiyana: ulusi wopota, wodzaza ndi wosaluka. Kupota ndiko kugwiritsa ntchito kofunika kwambiri kwa ulusi wamba, kuphatikizapo thonje ndi ubweya wopota mbali ziwiri. Kupota kwa thonje ndi ubweya kumatanthawuza kupota kwa thonje ndi ubweya wa ubweya. Kuchuluka kwa kupota kwa thonje ndi kwakukulu, kuphatikizapo poliyesitala koyera, thonje losakanizika la poliyesitala, poliyesitala-viscose wosakanikirana ndi kupanga ulusi wosoka wa polyester staple fiber. Kupota ubweya makamaka kumaphatikizapo polyester-nitrile, polyester-wool blend ndi kupanga mabulangete.

Kudzaza kumakhala ulusi waufupi wamtundu wa zodzaza, monga zodzaza m'nyumba ndi zida zotchinjiriza zovala, monga zoyala, zovala za thonje, mipando ya sofa, zoseweretsa zamtengo wapatali, monga kudzaza. Zambiri mwazitsulo zazikuluzikuluzi ndizitsulo zopanda kanthu za polyester. Nonwovens ndi njira yowonjezera yogwiritsira ntchito fiber fiber ndipo yakula mofulumira m'zaka zaposachedwa. Nsalu zopanda nsalu zimagwiritsidwa ntchito kwambiri, monga nsalu zopanda nsalu zomwe zimagwiritsidwa ntchito makamaka muzitsulo zonyowa, minda yachipatala, geotextiles, nsalu zachikopa, linoleum Kieb, etc. Pakadali pano, gawo lalikulu kwambiri pamsika wazogulitsa zoyambira za polyester staple fiber.
