Daim ntawv thov ntawm chav shrinking tshuab

Cov yam ntxwv ua haujlwm ntawm chav preshrinking tshuab yog preshrink yam tsis muaj zog thiab ncab cov ntaub.

Lub tshuab ua ntej shrinking tseem hu ua lub tshuab ua ntej shrinking. Nws muab faib ua ob hom: nruam chav shrinking tshuab haum rau cov ntaub plaub; Thaum tshav kub kub teeb shrinking tshuab haum rau hluavtaws fibers. Lwm cov ntaub tuaj yeem tau txais qee yam ua ntej shrinking nyhuv ntawm lub tshuab nqus tsev vacuum. Cov txheej txheem yooj yim yog moistening - steaming - rwb thaiv tsev thiab thermal shrinkage - txias thiab stabilization - ntaub tawm. Nws yuav tsum raug sau tseg tias kev ua haujlwm ntub dej ntawm cov ntaub ua ntej nkag mus rau hauv cov khoom siv steaming yuav tsum tsis sib xws, txwv tsis pub cov ntaub ntawv ua ntej shrinking yuav tsis sib xws. Txhawm rau kom tau txais daim ntaub pub rau hauv "tsis muaj lub xeev nruj", cov ntaub ntawv pub mis yuav tsum tau tswj hwm los ntawm kev hloov pauv zaus tsis muaj kev tswj hwm. Kev kho mob ua ntej shrinking ntawm fabrics hais txog los ntawm garment factories thiab "pre-shrinking finishing" ntawm fabrics los ntawm fabric finishing factories yog txawv nyob rau hauv cov nqe lus ntawm txheej txheem tswvyim. Lub tswv yim tseem ceeb ntawm cov tuam txhab tsoos tsho rau cov khoom ua ntej shrink yog manually tshem tawm cov shrinkage deformation nyhuv uas fabrics yuav tsim nyob rau hauv lub "natural aging" mob ua ntej garment processing.
