Plaub-txoj kev ncab feem ntau yog siv txoj kev ntxiv spandex elastic yarn rau cov ntaub kom cov ntaub elastic. Ua ntej, cov xov paj thiab spandex npog xov paj yog sib tw ua ke los ua cov xov paj elastic. Qhov ntev pub mis ntawm ob yuav tsum tau tswj nyias kom tswj tau qhov elasticity ntawm cov xov paj. Thaum lub sij hawm tsim thiab ua tiav, elongation ntawm cov xov paj thiab ntaub yuav tsum tau tswj kom tswj cov elasticity ntawm cov khoom tiav.
Plaub-txoj kev stretch ntaub yog warp thiab weft bidirectional stretch ntaub. Qhov dav dav elastic elongation yog 10% -15%, thiab cov ntsiab lus spandex hauv cov ntaub yog li 3%.
Qhov zoo ntawm plaub-txoj kev stretch fabrics:
1. Lub zog muaj zog. Lub zog ntawm luv fibers yog 2.6-5.7cN/dtex, thiab cov fibers siab zog yog 5.6-8.0cN/dtex. Lub zog hauv lub xeev ntub yog qhov pib zoo ib yam li hauv lub xeev qhuav. Lub zog cuam tshuam yog 4 npaug siab dua li ntawm nylon thiab 20 npaug siab dua li ntawm viscose fibers.
2. Zoo elasticity. Lub elasticity zoo ib yam li cov ntaub plaub. Thaum ncab los ntawm 5% -6%, nws tuaj yeem rov qab tau zoo. Lub wrinkle kuj yog qhov zoo tshaj rau lwm hom fibers, uas yog, cov ntaub tsis wrinkle thiab muaj qhov zoo ntawm qhov ntev. Lub elastic modulus yog 2-3 zaug siab dua li ntawm nylon. Nws muaj elasticity zoo thiab yog heev haum rau cov poj niam cov khaub ncaws. Cov poj niam elastic leggings uas tau nrov nyob rau hauv xyoo tas los no kuj siv tau rau khau, kaus mom, tsev textiles, khoom ua si, handicrafts, thiab lwm yam.
3. Zoo tiv thaiv tshav kub, thiab yuav tsis deform txawm nyob rau hauv high kub. Zoo lub teeb tsis kam. Lub teeb tsis kam yog thib ob tsuas yog acrylic. Qhov saum npoo yog du, cov molecules sab hauv yog nruj nreem kaw, thiab tsis muaj cov qauv hydrophilic ntawm cov molecules, yog li cov dej noo rov qab yog me me thiab cov dej nqus dej tsis zoo.
4. corrosion kuj. Resistant rau bleach, oxidants, hydrocarbons, ketones, roj av khoom thiab inorganic acids. Resistant rau dilute alkali, tsis ntshai ntawm mildew, tab sis kub alkali tuaj yeem ua rau nws decompose.
5. Zoo hnav tsis kam. Kev hnav tsis kam yog qhov thib ob nkaus xwb rau nylon, uas muaj qhov zoo tshaj plaws hnav tsis kam, thiab zoo dua li lwm cov fibers thiab hluavtaws fibers.
Qhov tsis zoo:
Cov xim ceev ceev ntawm plaub-txoj kev stretch fabrics feem ntau tsis siab, tshwj xeeb tshaj yog dub yog ib qho yooj yim mus ploj. Cov xim ntawm cov ntaub yog ib qho yooj yim kom tsis raug, thiab cov teeb meem xim txawv feem ntau tshwm sim. Qhov thib ob, qhov elasticity thiab qhov hnyav ntawm plaub-txoj kev stretch fleece yog qhov nyuaj rau tswj.
Nyob rau hauv luv luv, plaub-txoj kev stretch ntaub yog ib tug zoo heev ntaub, uas muaj qhov zoo ntawm softness thiab kev nplij siab, breathability zoo, muaj zog wrinkle kuj, zoo durability, thiab ntau haiv neeg tsim. Tab sis peb kuj yuav tsum tau xyuam xim rau qee cov ntsiab lus thaum siv nws, thiaj li tsis cuam tshuam rau lub neej kev pab cuam thiab cov nyhuv ntawm cov ntaub.
