Tshuaj fiber ntau: 4 ~ 8%
Paj rwb / Polyester: 3.5 ~ 5.5%
Ntuj Dawb Ntaub: 3%
Blue Nankeen: 3 ~ 4%
Poob: 3-4.5%
Paj Rwb: 3 ~ 3.5%
Tus nqi: 4%

Factors Influencing Shrinkage Rate
1. Raw khoom
Npuagua los ntawm cov khoom sib txawv muaj qhov sib txawv shrinkage tus nqi. Feem ntau hais lus, fiber ntau nrog hygroscopicity yuav nthuav dav tom qab soaking hauv dej. Nws txoj kab uas hla nce thiab nws qhov ntev txo, yog li tus nqi shrinkage yog loj. Piv txwv li, qhov nqus dej ntawm qee cov viscose fiber ntau tuaj yeem ncav cuag 13%. Thaum cov hluavtaws fiber ntau muaj qhov nqus dej tsis zoo, yog li nws qhov shrinkage yog me me.
2. Ceev
Fabrics muaj qhov sib txawv ntom muaj qhov sib txawv shrinkage. Yog hais tias warp-latitudinal ceev zoo ib yam, qhov warp-latitudinal shrinkage tus nqi zoo ib yam. Yog hais tias cov ntaub muaj warp ceev, nws warp shrinkage ntau dua. Piv txwv li, yog hais tias lub latitudinal ceev ntawm ntaub yog siab tshaj warp ceev, nws latitudinal shrinkage yog loj.
3.Lub thickness ntawm xov tooj suav
Npuag nrog cov xov paj sib txawv muaj qhov sib txawv shrinkage. Cov ntaub nrog cov xov paj tuab suav nrog tus nqi loj shrinkage. Thiab qhov shrinkage tus nqi ntawm cov ntaub nrog nyias yarn suav yog me me.
4.Cov txheej txheem tsim khoom
Fabrics los ntawm cov txheej txheem kev tsim khoom sib txawv muaj qhov sib txawv shrinkage tus nqi. Feem ntau, nyob rau hauv tus txheej txheem ntawm weaving,dyeingthiab ua tiav, cov fibers yuav tsum tau ncab ntau zaus thiab lub sijhawm ua haujlwm ntev. Npuag los ntawm kev nro ntau dua muaj qhov loj dua shrinkage.
5.Fiber muaj pes tsawg leeg
Muab piv nrog cov nroj tsuag regenerated fiber (xws li viscose fiber) thiab hluavtaws fiber (xws li polyester thiab acrylic fiber), natural plant fiber (xws li paj rwb thiab flax) yog ib qho yooj yim kom nqus noo noo thiab nthuav, yog li nws cov shrinkage tus nqi yog loj. Txawm li cas los xij, vim hais tias ntawm cov qauv ntsuas ntawm fiber ntau nto, ntaub plaub yog yooj yim rau felting, uas cuam tshuam nws qhov ntev stability.
6.Cov qauv ntawm cov ntaub
Feem ntau, qhov ruaj khov ntawm cov ntaub npuag yog zoo dua li ntawm cov ntaub knitted. Thiab qhov seem ruaj khov ntawm cov ntaub ceev ntom ntom yog qhov zoo dua li ntawm cov ntaub ceev qis. Hauv woven fabrics, qhov shrinkage tus nqi ntawm cov ntaub qhwv dawb yog me dua li ntawm cov ntaub flannel. Nyob rau hauv knitted fabrics, lub shrinkage tus nqi ntawm dawb stitch ntaub yog me dua li ntawm leno ntaub.
7.Kev tsim khoom thiab kev ua haujlwm
Thaum lub sij hawm dyeing, luam ntawv thiab xov, fabrics yuav inevitably raug stretched los ntawm lub tshuab. Yog li ntawd muaj tensions ntawm fabrics. Txawm li cas los xij, cov ntaub yog ib qho yooj yim los tso cov nro thaum lawv raug dej. Yog li ntawd, peb yuav pom tias cov ntaub shrinks tom qab ntxuav. Hauv cov txheej txheem tiag tiag, peb feem ntau daws cov teeb meem no los ntawm kev ua ntej shrinking.
8. Ntxuav thiab tu txheej txheem
Ntxuav thiab tu muaj xws li ntxuav, ziab thiab ironing, tag nrho cov uas yuav cuam tshuam rau shrinking ntawm fabrics. Piv txwv li, qhov kev ruaj ntseg ntawm cov qauv ntxuav tes yog qhov zoo dua li cov qauv ntawm cov tshuab ntxhua. Thiab qhov kub thiab txias yuav cuam tshuam qhov kev ruaj ntseg ntawm qhov ntev. Feem ntau, qhov kub thiab txias yog siab dua, qhov seem stability tsis zoo.
Cov txheej txheem siv ziab qhuav yog drip drying method, hlau mesh flat drying method, hanging drying method and rotary drying method. Ntawm, drip drying txoj kev cuam tshuam qhov tsawg tshaj plaws ntawm qhov ntev ntawm cov ntaub. Rotary drying method influences feem ntau ntawm qhov ntev ntawm cov ntaub. Thiab ob txoj hauv kev yog nyob nruab nrab.
Tsis tas li ntawd, xaiv qhov tsim nyog ironing kub raws li cov ntaub ntawv muaj pes tsawg leeg yuav txhim kho lub shrinkage mob. Piv txwv li, lub shrinkage ntawm fabrics ntawm paj rwb thiab flax tuaj yeem txhim kho los ntawm kev kub kub ironing. Tab sis qhov kub siab dua tsis yog ib txwm zoo dua. Rauhluavtaws fibers, kub kub ironing yuav tsis txhim kho nws cov shrinkage tus nqi, tab sis yuav ua rau nws cov kev ua tau zoo. Piv txwv li, fabrics yuav nyuaj thiab nkig.
