Dab tsi ntawm cov ntaub yog spandex?
Spandex yog ib hom polyurethane fiber ntau.Vim nws cov elasticity zoo heev, nws tseem hu ua elastic fiber, uas tau siv dav hauv cov khaub ncaws fabrics.Cov yam ntxwv tseem ceeb ntawm spandex ntaub yog: (1) elasticity ntawm spandex yog siab heev.Feem ntau, cov khoom tsis siv 100% polyurethane, thiab feem ntau, 5% mus rau 30% polyurethane yog sib xyaw rau hauv cov ntaub, ua rau muaj ntau yam ntawm spandex fabrics uas khav 15% mus rau 45% ntawm cov elasticity. 2) Cov ntaub spandex feem ntau yog ua los ntawm cov xov paj sib xyaw.Nws txhais tau hais tias spandex yog cov tub ntxhais thiab lwm cov fibers (xws li nylon, polyester, thiab lwm yam) yog lub cortex los npog cov xov paj elastic ntaub, uas boasts zoo adaptability rau lub cev thiab yog lub zoo tagnrho raw khoom rau tights, muab tsis muaj kev nkag siab ntawm siab.
(3) Cov qauv zoo nkauj thiab hnav tau ntawm spandex elastic ntaub yog ze rau cov khoom zoo li nws cov coated fiber ntau ntaub.
Dab tsi yog qhov ci ntsa iab ntawm cov khaub ncaws ua los ntawm spandex?
1. Qhov zoo tshaj plaws ntawm spandex ntaub yog nws cov elasticity zoo, uas tuaj yeem ncav cuag 5 mus rau 8 zaug tsis muaj kev laus.Spandex tsis tuaj yeem woven ib leeg thiab feem ntau woven nrog lwm cov ntaub ntawv raw.Cov ntsiab lus ntawm spandex yog li ntawm 3 mus rau 10%, thiab hauv cov khaub ncaws swimwear tuaj yeem ncav cuag 20%.
2. Spandex fiber ntau yog cov hluavtaws fiber ntau nrog siab elongation ntawm kev tawg (tshaj 400%), tsis tshua muaj modulus thiab siab elastic rov qab tus nqi.Nws yog Suav lag luam npe ntawm multi-thaiv polyurethane fiber ntau, tseem hu ua elastic fiber.Spandex muaj elongation siab (500% mus rau 700%), tsis tshua muaj elastic modulus (200% elongation, 0.04 mus rau 0.12 g / denier) thiab siab elastic rov qab tus nqi (200% elongation, 95% mus rau 99%).Nws lub cev thiab cov khoom siv kho tshuab zoo ib yam li cov hlau latex ntuj tshwj tsis yog nws lub zog siab.Nws tiv taus cov tshuaj degradation dua li latex txhob lo lo ntxhuav, thiab muaj qhov nruab nrab thermal stability nrog softening kub ntawm li 200 ℃ los yog ntau tshaj.Feem ntau cov dyes thiab xov cov neeg ua hauj lwm siv nyob rau hauv hluavtaws thiab ntuj fibers kuj haum rau dyeing thiab xov spandex.Spandex tiv taus hws, dej hiav txwv thiab ntau yam tshuaj ntxuav qhuav thiab tshuaj pleev thaiv hnub feem ntau.Nws kuj tseem yuav ploj mus ntev nrog lub hnub ci lossis cov tshuaj chlorine bleach, tab sis cov degree ntawm fading txawv heev nrog hom spandex.Spandex yog polyurethane fiber ntau.Vim nws cov elasticity zoo heev, nws tseem hu ua elastic fiber, uas tau siv dav hauv cov khaub ncaws fabrics nrog cov yam ntxwv xws li siab elasticity.Spandex ntaub yog tsuas yog siv nyob rau hauv kev tsim cov tights, sportswear, tiv thaiv pluaj thiab soles.Nws ntau yam raws li kev xav tau ntawm kev siv, tuaj yeem muab faib ua warp elastic ntaub, weft elastic ntaub thiab warp thiab weft bi-directional elastic ntaub.
Cov yam ntxwv ntawm Spandex Fiber Fabric thiab Daim Ntawv Thov ntawm Spandex
Spandex yog ib hom polyurethane fiber ntau.Vim nws cov elasticity zoo heev, nws tseem hu ua elastic fiber, uas tau siv dav hauv cov khaub ncaws fabrics.
1. Cov yam ntxwv tseem ceeb ntawm spandex fiber ntau ntaub
(1) Lub elasticity ntawm spandex yog siab heev.Feem ntau, cov khoom tsis siv 100% polyurethane, thiab feem ntau, 5% mus rau 30% polyurethane yog sib xyaw rau hauv cov ntaub, ua rau muaj ntau yam ntawm spandex fabrics uas khav theeb 15% mus rau 45% ntawm qhov zoo elasticity.
(2) Cov ntaub spandex feem ntau yog ua los ntawm cov xov paj sib xyaw.Nws txhais tau hais tias spandex yog cov tub ntxhais thiab lwm cov fibers (xws li nylon, polyester, thiab lwm yam) yog lub cortex los npog cov xov paj elastic ntaub, uas boasts zoo adaptability rau lub cev thiab yog lub zoo tagnrho raw khoom rau tights, muab tsis muaj kev nkag siab ntawm siab.
(3) Cov qauv zoo nkauj thiab hnav tau ntawm spandex elastic ntaub yog ze rau cov khoom zoo li nws cov coated fiber ntau ntaub.
2. Daim ntawv thov ntawm spandex
(1) Spandex fiber tuaj yeem siv rau kev tsim cov khaub ncaws uas tuaj yeem ncab kom tau raws li kev nplij siab.Piv txwv li: Cov khaub ncaws ua kis las ncaws pob, cov khaub ncaws ua haujlwm thiab cov khaub ncaws ua si, hnav khaub ncaws dhia dej, da dej suits, da dej suits rau kev ua si, cov khaub ncaws ntaus pob, khiab mis thiab cov hlua khi, cov ris caij ski, khaub ncaws rau disco, ris tsho hauv qab, ris xws li, thom khwm, ceg sov so, pawm , ris nruj, siv, ris tsho hauv qab, jumpsuits, spandex close-fitting khaub ncaws, bandages siv los ntawm cov txiv neej ballet dancers, tiv thaiv khaub ncaws rau kev phais, tiv thaiv khaub ncaws siv los ntawm kev pab txhawb nqa, lub tes tsho luv luv rau kev caij tsheb kauj vab, wrestling tsho khuam, nplua rau kev caij nkoj, ris tsho hauv qab , kev ua haujlwm khaub ncaws, khaub ncaws zoo, brassiere, kho kom zoo nkauj hauv tsev, micro-bead hauv ncoo, thiab lwm yam.
(2) Spandex tsis tshua siv rau hauv cov khaub ncaws dav dav.Hauv North America, nws tau siv tsawg dua ntawm cov txiv neej cov khaub ncaws thiab ntau dua ntawm cov poj niam cov khaub ncaws.Vim cov poj niam cov khaub ncaws yuav tsum tau nyob ze rau lub cev.Hauv kev siv, nws yuav muab sib xyaw nrog ntau lwm cov fibers xws li paj rwb thiab polyester thiaj li yuav txo qhov gloss kom tsawg.
