Koj Paub Ntau npaum li cas txog tsib feem ntau siv Elastane?

Lub ntsiab txhais ntawm elastane

Elastane yog tus cab nrog siab elongation thiab resilience.Lub ntsiab lus classic tshaj plaws yog: "Ib hom fiber ntau uas nyob rau hauv chav tsev kub, cov khoom siv tau txuas ntxiv mus rau qhov tsawg kawg yog ob zaug nws qhov ntev, thiab tom qab qhov nro tawm, nws tuaj yeem rov qab mus rau qhov qub ntev."Thiab rau cov ntaub ntawv polyurethane, nws yog hais txog ib hom fiber ntau uas yog ncab mus rau qhov qub ntev ntawm peb zaug, thiab tom qab qhov nro tawm, nws tuaj yeem rov qab mus rau qhov qub ntev.Tsis tas li ntawd, nyob rau hauv txawv teb chaws thiab cheeb tsam, muaj ib co lwm yam txhais.

Ntawm cov khoom lag luam ntau yam nrog cov haujlwm sib txawv, elastane, raws li "kev lag luam hnub ci", ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov khoom xws li hnav kev nplij siab, softness thiab warmth ntawm cov khaub ncaws los ntawm kev muab tib neeg zoo kov lub siab, thiab yog li occupies ib qho chaw ruaj khov nyob rau hauv ntiaj teb no textile kev lag luam.Tsis tas li ntawd, nws tau dhau los ua ib qho kev tsis pom zoo rau cov khoom siv textile nrog qee qhov elasticity hauv kev lag luam textile.

Cov hom ntawm elastane ntau

1. Alkene hom elastane (rubber xov)

Diolefins elastane feem ntau hu ua roj hmab xov lossis elastic xov, qhov elongation feem ntau yog nyob nruab nrab ntawm 100% mus rau 300%.Cov tshuaj tseem ceeb ntawm nws yog sulfide polyisoprene.Nws muaj qhov kub thiab txias tsis kam, acid thiab alkali tsis kam, hnav tsis kam thiab lwm yam tshuaj thiab lub cev, uas yog siv dav hauv cov thom khwm, ribbed cuffs thiab lwm yam kev lag luam knitting.Roj hmab xov yog ib hom elastane siv nyob rau hauv thaum ntxov theem.Vim nws yog tsuas yog ua rau cov xov paj ntxhib, nws siv nyob rau hauv weaving fabrics yog txwv.

2. Polyurethane fiber ntau (spandex) Polyurethane elastane yog hais txog ib hom fiber ntau ua los ntawm kev thaiv copolymer nrog polycarbamate ua cov khoom tseem ceeb.Spandex yog qhov ntxov tshaj plaws tsim thiab feem ntau siv elastane nrog cov cuab yeej tsim khoom loj tshaj plaws.

3. Polyether ester elastane

4. Polyolefin elastane (DOW XLA fiber ntau)

5. Composite elastane (T400 fiber ntau)
