Taw Qhia Rau Spandex Xov Paj Feem ntau siv hauv cov ntaub qhwv thiab nws cov khoom tseem ceeb!
Nrog rau kev txhim kho ntawm tib neeg kev ua neej nyob, cov kev xav tau ntawm cov ntaub siv los ua cov khaub ncaws tau nce siab dua. Tshwj xeeb tshaj yog thaum tib neeg tab tom tawm dag zog lossis ua haujlwm, cov khaub ncaws zoo tib yam feem ntau tsis muaj qhov ncab zoo, uas ua rau muaj kev nkag siab thiab tsis xis nyob thaum hnav. Yog li ntawd, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev ua haujlwm elastic stretch ntawm textile khaub ncaws fabrics. Nyob rau hauv kev muaj tiag, ntau stretch fabrics yog ua los ntawm spandex yarn kom cov ntaub muaj zoo elasticity, thiab spandex xov paj yog ua los ntawm spandex fiber. Cia peb qhia txog txoj kev ua cov xov paj spandex thiab nws cov khoom tseem ceeb!
Spandex xov paj yog ua los ntawm spandex fiber!
Spandex stretch fiber yog sib xyaw nrog lwm cov fibers rau spin stretch yarn. Tam sim no muaj peb hom ntawm nws cov xov paj: spandex core-spun yarn, spandex twisted yarn thiab spandex cov xov paj. Peb daim ntawv xov paj muaj qhov sib txawv tseem ceeb hauv kev ua cov qauv thiab cov khoom siv. Yog li ntawd, lawv cov kev siv thiab cov khoom siv weaving kuj txawv heev.
Dab tsi yog lub hauv paus ntawm spandex thiab nws cov khoom tseem ceeb?
Spandex yog ua los ntawm spandex fiber ntau los ntawm cov txheej txheem spinning. Spandex fiber yog ib hom elastic fiber. Elastic fiber yog hu ua spandex txawv teb chaws. Cov khoom npe hauv kuv lub teb chaws yog spandex. Qhov tseeb, spandex tsuas yog ib pawg loj ntawm elastic fiber. Spandex fiber (Polyurethane Fibre) yog hu ua PU fiber. Muaj ob hom. Ib qho yog copolymer ntawm aromatic diisocyanate thiab polyester ntu uas muaj hydroxyl pawg, hu ua polyester spandex, thiab lwm yam yog ib tug copolymer ntawm aromatic diisocyanate thiab polyether ntu uas muaj hydroxyl pawg, hu ua polyether spandex. Tus neeg sawv cev cov khoom npe ntawm polyester spandex yog Vyrent, thiab tus neeg sawv cev khoom npe ntawm polyether spandex yog Lyera.
Cov khoom tseem ceeb ntawm spandex yog: feem ntau ntau dua 500% mus rau 700% elongation, zoo elastic rov ua haujlwm. Nws shrinks 97% thaum nws yog elongated los ntawm 200%, thiab shrinks ntau tshaj 99% thaum nws yog elongated los ntawm 50%. Cov txheeb ze ntawm ntau yam spandex yog me me, feem ntau 1.20-1.25, thiab lub zog tawg yog 4.41-8.82 cN/tex (0.5-1.0 g/ tsis kam). Lub zog ntawm polyester spandex qis dua, thaum lub zog ntawm polyether spandex siab dua. Kev nqus dej noo feem ntau yog 0.3%-1.2%, thiab qhov nqus dej noo ntawm cov khoom siv ntau dua me ntsis siab dua li ntawm monofilament. Lub tshav kub tsis kam yog feem ntau 95-150 degree , thiab lub sij hawm luv luv yuav tsis ua rau cov fiber ntau. Qhov kev nyab xeeb ironing kub yog qis dua 150 degree. Cov fibers hlawv maj mam thiab tsim cov gelatinous residue tom qab hlawv. Nws muaj kev ua tau zoo dyeing zoo, tuaj yeem dyed nyob rau hauv ntau yam xim, thiab muaj ib tug muaj zog affinity rau dyes.
Lub tiab yog ua los ntawm plaub-sided stretch suede ntaub. Cov ntaub yog ntxiv nrog 40D spandex, thiab cov ntsiab lus spandex suav rau 10%. Nws yog ze-haum, xis, thiab mos, ua tsaug rau spandex!
