Kuyang'anira Nsalu:
Nsalu iyi imatha kukwaniritsa muyezo wa GB/T, muyezo wa ISO, muyezo wa JIS, ndi muyezo wa US. Nsalu zonse zidzayang'aniridwa 100 peresenti zisanatumizidwe malinga ndi muyezo wa American four point system.
Kodi Nsalu ya Elastane Imapangidwa Bwanji?
Njira zinayi zosiyanasiyana zingagwiritsidwe ntchito popanga nsalu yotanuka iyi: Kuzungulira kwa reaction, kuzunguliza kwa solution wet, kusungunula kwa melt, ndi kuzunguliza kwa solution dry spinning. Njira zambiri zopangira izi zatayidwa ngati zosagwira ntchito bwino kapena zowononga ndalama, ndipo kuzunguliza kwa solution dry spinning tsopano kumagwiritsidwa ntchito kupanga pafupifupi 95 peresenti ya spandex yomwe imapezeka padziko lonse lapansi.
Njira yozungulira youma ya yankho imayamba ndi kupanga prepolymer, yomwe imagwira ntchito ngati maziko a nsalu ya elastane. Gawoli limakwaniritsidwa posakaniza macroglycol ndi diisocyanate monomer mkati mwa chotengera chapadera cha reaction. Pamene zinthu zoyenera zikugwiritsidwa ntchito, mankhwala awiriwa amalumikizana wina ndi mnzake kuti apange prepolymer. Chiŵerengero cha voliyumu pakati pa zinthu ziwirizi n'chofunika kwambiri, ndipo nthawi zambiri, chiŵerengero cha glycol ndi diisocyanate cha 1:2 chimagwiritsidwa ntchito.
Pamene njira yozungulira youma imagwiritsidwa ntchito, prepolymer iyi imayanjanitsidwa ndi diamine acid mu njira yotchedwa chain extension reaction. Kenako, yankho ili limachepetsedwa ndi solvent kuti likhale lopyapyala komanso losavuta kugwiritsa ntchito, kenako limayikidwa mkati mwa selo yopanga ulusi.
Selo ili limazungulira kuti lipange ulusi ndikuchiritsa zinthu za elastane. Mkati mwa selo ili, yankho limakankhidwira kudzera mu spinneret, yomwe ndi chipangizo chomwe chimawoneka ngati mutu wa shawa wokhala ndi mabowo ang'onoang'ono ambiri. Mabowo awa amapanga yankho kukhala ulusi, ndipo ulusiwu umatenthedwa mkati mwa yankho la nayitrogeni ndi mpweya wosungunulira, zomwe zimayambitsa kusintha kwa mankhwala komwe kumapanga polima yamadzimadzi kukhala zingwe zolimba.
Zingwezo zimasonkhanitsidwa pamodzi pamene zikutuluka mu selo lozungulira lozungulira ndi chipangizo choponderezedwa cha mpweya chomwe chimazipotoza. Ulusi wopotokawu ukhoza kupangidwa m'njira zosiyanasiyana zokhuthala, ndipo ulusi uliwonse wa elastane mu zovala kapena ntchito zina zimapangidwa kuchokera ku ulusi wambiri waung'ono womwe wadutsa munjira yopotoka iyi.
Kenako, magnesium stearate kapena polima ina imagwiritsidwa ntchito pokonza zinthu za elastane ngati chomaliza, zomwe zimaletsa ulusi kuti usamamatire wina ndi mnzake. Pomaliza, ulusi uwu umasamutsidwira ku spool, ndipo kenako umakhala wokonzeka kupakidwa utoto kapena kuluka ulusi.
