Elastane thiab polyester tsis yog tib yam khoom, thiab lawv muaj qee qhov sib txawv tseem ceeb:
- Cov Khoom Siv: Polyester yog cov khoom siv hluavtaws ua los ntawm cov khoom siv polymer hu ua polyethylene terephthalate (PET), uas yog tsim los ntawm cov tshuaj tiv thaiv condensation ntawm terephthalic acid thiab ethylene glycol. Nws yog hom yas uas paub txog nws lub zog thiab kub ua haujlwm. Elastane, tseem hu ua spandex, yog ib qho elastic fiber ntau ua los ntawm polyether-polyurea copolymer, uas yog muab los ntawm roj av los ntawm cov txheej txheem nyuaj. Nws paub txog nws qhov tshwj xeeb elasticity.
- Elasticity: Elastane muaj npe nrov rau nws cov elasticity zoo dua, muaj peev xwm ncav cuag 500% ntawm nws qhov qub ntev thiab rov qab mus rau nws qhov qub qub. Qhov no ua rau nws muaj txiaj ntsig zoo hauv cov khaub ncaws uas xav tau kev ncab thiab kev nplij siab, xws li leggings thiab sportswear. Polyester, thaum muaj qee qhov elasticity zoo ib yam li ntaub plaub, tsis piv rau qhov stretchability ntawm elastane.
- Durability: Txawm hais tias elastane excels hauv elasticity, nws tsis tshua muaj zog dua polyester. Elastane fibers tuaj yeem poob lawv elasticity nyob rau lub sijhawm nrog rov ncab thiab ntxuav. Polyester, ntawm qhov tod tes, paub txog nws cov kav ntev thiab tsis kam hnav thiab tsim kua muag, ua rau nws haum rau cov khaub ncaws sab nraum zoov thiab cov khoom ua si.
- Cov txheej txheem ntau lawm: Elastane feem ntau yog tsim los siv cov txheej txheem qhuav spinning, uas ua rau cov fibers nrog elasticity siab. Polyester yog tsim los ntawm cov txheej txheem melting, qhov twg molten PET yog extruded los ntawm spinneret los tsim fibers uas solidify thaum txias.
- Environmental Impact: Ob qho khoom siv yog hluavtaws thiab muaj kev cuam tshuam ib puag ncig zoo sib xws. Lawv tsis yog biodegradable thiab tuaj yeem tsim tau siv cov tshuaj phem.
- Tus nqi: Polyester feem ntau tsis tshua muaj nqi los tsim dua elastane vim nws txoj kev tsim khoom yooj yim dua thiab tsis tshua muaj nqi, uas yog vim li cas polyester tau siv dav hauv khaub ncaws.
Txawm hais tias ob qho tib si elastane thiab polyester yog hluavtaws fibers, lawv muaj cov qauv tshuaj sib txawv, lub cev, thiab kev siv. Elastane feem ntau yog siv rau nws elasticity, thaum polyester muaj nuj nqis rau nws cov durability thiab nqi-zoo.
