Stretch yarn, filament los yog staple yarn nrog siab elastic elongation thiab ceev rov qab.

Stretch yarn, filament los yog staple yarn nrog siab elastic elongation thiab ceev rov qab. Nws yog ib hom bulking xov paj.

Raws li qhov elastic elongation loj tuaj yeem muab faib ua: (1) siab elastic yarn, elastic elongation yog li ntawm 30 feem pua ​​​​~ 50 feem pua, nrog cov thermoplastic filament los ntawm qhov chaw kub thiab tsis muaj qhov sib tw deformation lossis riam ntug curling deformation ntawm cov xov paj, spandex elastic filament thiab lwm cov xov paj sib xyaw ua los ntawm cov xov paj, siv rau kev ua cov khoom zoo elastic, thom khwm, swimsuits, khaub ncaws kis las, thiab lwm yam. Kev teeb tsa kev kho mob ntawm cov xov paj, cov xov paj tseem ceeb ua los ntawm spandex elastic filament yarn li cov xov paj tseem ceeb thiab cov xov paj sib xyaw staple fiber ntau sib xyaw nrog elastic fiber, siv rau kev ua haujlwm tsis tshua muaj elasticity, tab sis yuav tsum muaj kev xav zoo thiab zoo li ntawm cov ntaub, rooj tog ntaub, thiab lwm yam.
