Desizing
Desizing yog rau sizing woven fabrics. Rau weaving yooj yim, feem ntau ntawm cov ntaub woven xav tau sizing ua ntej woven. Cov txheej txheem desizing feem ntau yog dej kub desizing, alkali desizing, enzyme desizing thiab oxidation desizing. Yog tias cov ntaub tsis muaj qhov loj me, qhov dye up-take of dyes yuav raug cuam tshuam thaum lub sij hawm dyeing, los yog tus kov ntawm fabrics yuav ua tsis zoo.
Degreasing
DegreasingFeem ntau yog rau cov khoom siv fiber ntau (lossis cov xov paj), xws li polyester thiab nylon, thiab lwm yam. Yog tias cov ntaub tsis zoo degreased, nws tseem yuav cuam tshuam cov nyhuv dyeing thiab ua rau cov roj stain thiab xim stain, thiab lwm yam.
Txo qhov hnyav
Fiber splitting yog rau tshuaj fiber ntau fabrics, xws li polyester microfiber, hiav txwv-kob fiber ntau thiab polyester / nylon blends, thiab lwm yam. Kev sib cais yuav cuam tshuam rau dyeing xim ceev thiab dyeing ntxoov ntxoo stability. Feem ntau, nws yog los tswj cov nyhuv splitting los ntawm qhov hnyav poob piv ntawm splitting.
Kev nplawm
Kev nplawmFeem ntau yog tsom rau cov fibers ntuj thiab regenerated cellulose fibers. Lub hom phiaj yog tshem tawm impurities xws li roj, ciab thiab pectin los ntawm fibers. Lub ntsiab Performance index ntawm scouring yog capillary nyhuv. Cov nyhuv capillary yuav cuam tshuam ncaj qha rau cov dye up-take thiab dyeing evenness.
Tshuaj dawb
Bleaching feem ntau yog tsom rau cov fibers ntuj thiab cov cellulose regenerated fibers. Lub hom phiaj ntawm bleaching yog tshem tawm cov xim teeb meem kom ua tiav whiteness. Rau cov xim rhiab thiab ci ntsa iab, qhov ruaj khov ntawm cov tshuaj dawb huv yog qhov tseem ceeb.
Xaus
Txhawm rau txhim kho qhov ua tiav ib zaug ntawm dyeing, nws yuav tsum tau tswj txhua qhov ntsuas ntawm pretreatment, raws li qib desizing, degreasing tus nqi, splitting npaum li cas, capillary nyhuv, yuag poob thiab whiteness, thiab lwm yam. Yog hais tias tag nrho cov indexes yog ruaj khov, uas. txhais tau tiasdyeingyog ib nrab kev vam meej.
