Kodi Elastane Fabric Amapangidwa Bwanji?

Njira zinayi zosiyanasiyana zingagwiritsidwe ntchito popanga nsalu zotanuka izi: kupota kwa Reaction, njira yonyowa kupota, kusungunula kutulutsa, ndi kupota kowuma.Zambiri mwa njira zopangira izi zatayidwa monga zosagwira ntchito bwino kapena zowononga, ndipo njira yopopera yowuma tsopano imagwiritsidwa ntchito kupanga pafupifupi 95 peresenti ya spandex yapadziko lonse lapansi.
Njira yothetsera kupota kowuma imayamba ndi kupanga prepolymer, yomwe imakhala ngati maziko a nsalu ya elastane.Izi zimatheka posakaniza macroglycol ndi diisocyanate monomer mkati mwa chotengera chapadera chotengera.Pamene mikhalidwe yoyenera ikugwiritsidwa ntchito, mankhwala awiriwa amalumikizana wina ndi mzake kuti apange prepolymer.Chiŵerengero cha voliyumu pakati pa zinthu ziwirizi ndizovuta, ndipo nthawi zambiri, chiŵerengero cha glycol ku diisocyanate cha 1: 2 chimagwiritsidwa ntchito.
Njira yozungulira yowuma ikagwiritsidwa ntchito, prepolymer iyi imayendetsedwa ndi diamine acid munjira yotchedwa chain extension reaction.Kenako, yankholi limachepetsedwa ndi zosungunulira kuti likhale locheperako komanso losavuta kugwira, kenako limayikidwa mkati mwa cell yopanga ulusi.
Selo iyi imazungulira kupanga ulusi ndikuchiritsa elastane.Mkati mwa seloli, yankho limakankhidwa kudzera pa spinneret, chomwe ndi chipangizo chomwe chimawoneka ngati mutu wa shawa wokhala ndi timabowo tambirimbiri.Tizibowo timeneti timapanga chitsulocho kukhala ulusi, ndipo ulusi umenewu umatenthedwa ndi mpweya wa nayitrojeni ndi wosungunulira, umene umapangitsa kuti pakhale zinthu zina zomwe zimapanga polima wamadzimadzi kukhala ulusi wolimba.
Zingwezo zimamangidwa pamodzi pamene zikutuluka mu selo lozungulira lozungulira ndi chipangizo cha mpweya chomwe chimachipiringa.Ulusi wopotokawu ukhoza kupangidwa mosiyanasiyana mosiyanasiyana, ndipo ulusi uliwonse wa elastane wovala kapena ntchito zina umapangidwa kuchokera ku tizingwe tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono, ulusi wa elastane umakhala wopangidwa kuchokera ku tizingwe tating'ono tating'ono tomwe tapindika.
Kenako, magnesium stearate kapena polima wina amagwiritsidwa ntchito pochiza elastane ngati chomaliza, chomwe chimalepheretsa ulusi kumamatira wina ndi mnzake.Pamapeto pake, ulusi umenewu umasamutsidwa ku spool, ndipo umakhala wokonzeka kupakidwa utoto kapena kuwomba kuti ukhale ulusi.
