Qhov sib txawv tseem ceeb ntawm elastane thiab spandex yog elastane yog cov khoom siv hluavtaws uas yog Spandex yog lub npe rau cov khoom siv elastane.
Elastane yog fiber ntau uas tsis tshwm sim ib txwm muaj tab sis yog tsim los ntawm ntau txoj kev lag luam. Muaj ob lub npe loj rau cov khoom siv elastane li Spandex thiab Lycra. Muaj qhov sib txawv me ntsis ntawm ob cov ntaub ntawv nyob ntawm tus neeg tsim khoom.
YElastane yog dab tsi?
Elastane yog lub npe siv rau cov npe xws li Spandex thiab Lycra. Hauv lwm lo lus, cov khoom siv elastane muaj nyob rau hauv ob lub npe: Spandex thiab Lycra. Cov khoom siv no feem ntau yog siv hauv kev lag luam textile ua ntaub. Qhov zoo kawg elasticity ntawm cov khoom no ua rau nws muaj txiaj ntsig zoo hauv kev lag luam textile. Lo lus no feem ntau yog siv nyob rau hauv cheeb tsam European.
Elastane yog cov khoom siv polyether-polyurea copolymer. Cov khoom no tau tsim nyob rau xyoo 1958 los ntawm tus kws kho mob Joseph Shivers ntawm Dupont lub chaw kuaj mob. Muaj rau txoj hauv kev loj ntawm kev tsim cov elastane fiber ntau: yaj extrusion, tshuaj tiv thaiv spinning, tov qhuav spinning thiab tov ntub spinning. Plaub txoj hauv kev no suav nrog cov kauj ruam pib ntawm reacting monomers los tsim cov khoom siv prepolymer. Cov prepolymer no ces reacted nyob rau hauv cov kev sib txawv no kom tau cov elastane fiber ntau. Txawm li cas los xij, ntau dua 90% ntawm cov khoom siv elastane yog tsim los ntawm kev daws cov txheej txheem qhuav spinning.

Elastane muaj qhov tshwj xeeb elasticity, uas tuaj yeem ua rau cov khaub ncaws ua kom lub siab xis nyob, ua kom yooj yim ntawm lub cev txav. Lub sij hawm kev nplij siab yog hais txog cov lus teb rau khaub ncaws los ntawm lub siab receptors ntawm tib neeg lub cev. Cov yam ntxwv zoo ntawm cov khoom kom tau txais kev nplij siab muaj xws li stretchiness, hu nkauj, xoob, hnyav, hnav, mos, thiab cov yam ntxwv nruj. Lub siab nplij siab yog superior nrog cov ntaub ntawv elastane.
Spandex yog dab tsi?
Spandex yog lub npe nrov rau cov khoom siv elastane thiab muaj lub ntsiab lus "nthuav dav". Lub npe hom no yog lub ntsiab lus nyiam nyob rau hauv North America, tab sis nyob rau hauv lwm cheeb tsam ntawm lub ntiaj teb no, lwm lub npe yog siv los xa mus rau cov khoom no. Lycra yog lwm lub npe rau cov khoom siv tib yam tab sis muaj qhov sib txawv me ntsis.

Kev siv loj ntawm Spandex hom suav nrog kev tsim cov khoom siv xws li hnab looj tes thiab thom khwm, cov khoom siv kis las xws li kev sib tw ua luam dej, lub cev xws li wetsuits, hauv qab xws li leggings, thiab lwm yam.
Qhov txawv ntawm Elastane thiab Spandex yog dab tsi?
Ob lub npe elastane thiab Spandex hais txog tib yam khoom, tab sis lawv txawv ntawm cov ntsiab lus vim Spandex yog lub npe rau cov khoom siv elastane. Qhov sib txawv tseem ceeb ntawm elastane thiab spandex yog tias elastane yog cov khoom siv hluavtaws, thaum Spandex yog lub npe rau cov khoom siv elastane. Ntxiv mus, lo lus elastane feem ntau yog siv nyob rau hauv cheeb tsam European, thaum lub sij hawm spandex yog siv nyob rau hauv North America.
Summary – Elastane vs Spandex
Spandex thiab Lycra yog ob lub npe loj rau cov khoom siv elastane. Elastane yog cov khoom siv polyether-polyurea. Qhov sib txawv tseem ceeb ntawm elastane thiab spandex yog tias elastane yog cov khoom siv hluavtaws, thaum Spandex yog lub npe rau cov khoom siv elastane. Ntxiv mus, lo lus elastane yog siv nyob rau hauv cov teb chaws Europe, thaum lub npe hom Spandex yog siv nyob rau hauv lub North American cheeb tsam.
