Recycled polyester fabrics txuag ze li ntawm 80% ntawm lub zog piv rau cov pa polyester fabrics, uas tuaj yeem txo qis kev siv roj. Cov ntaub ntawv qhia tau hais tias txhua tuj ntawm cov xov paj siv polyester tuaj yeem txuag tau 1 tuj roj thiab 6 tons dej. Yog li ntawd, kev siv cov ntaub polyester rov ua dua tshiab yog qhov tseem ceeb heev rau kev txo qis carbon emission txo txoj kev loj hlob ruaj khov uas tau tawm tswv yim los ntawm kuv lub teb chaws. Dab tsi yog qhov yuav tsum tau ua rau dyed yarn? Qhov tseeb, zoo li lwm cov khoom siv xov paj, cov xov paj dyed kuj yog cov xov paj tsim los ntawm ntau cov txheej txheem ntau lawm, nrog rau cov yam ntxwv zoo dua thiab ua tiav ntau dua. Dyed yarn, raws li cov xov paj tsim los ntawm ntau cov txheej txheem ntau lawm, muaj cov yam ntxwv zoo dua thiab ua tiav ntau dua.
Yooj yim dyeing Modal fiber tuaj yeem ua tiav los ntawm cov txheej txheem cellulose fiber ntau pretreatment, bleaching thiab dyeing txheej txheem. Cov tsoos cellulose fiber ntau dyeing dyes, xws li dyes ncaj qha, vat dyes, sulfur dyes thiab azo dyes yuav siv tau rau modal ntaub dyeing, thiab nrog tib tus nqi dyeing, modal fabrics muaj xim zoo dua, ci dua thiab ci dua, thiab yuav mercerized thaum blended. nrog paj rwb, thiab dyeing yog uniform, ntom, thiab xim yog khaws cia. Txawm hais tias cov ntaub ploj los yog tsis muaj dab tsi cuam tshuam nrog cov xov paj muaj pes tsawg leeg thiab cov qauv tsim ntawm cov ntaub.
Cov dyes siv los zas xim ntshiab paj rwb ntaub mas suav nrog dyes ncaj qha, vat dyes, soluble vat dyes, insoluble azo dyes, sulfur dyes, thiab lwm yam. dyes thiab printing coatings. Viscose fibers, uas zoo ib yam li paj rwb fibers, kuj tuaj yeem dyed thiab luam tawm nrog cov dyes saum toj no. Txawm li cas los xij, txij li cov viscose fibers yog cellulose fibers, piv nrog paj rwb fibers, lawv tsis resistant rau alkali thiab ntau resistant rau acid, yog li thaum dyeing nrog tib hom dyes, yuav tsum muaj qee qhov sib txawv ntawm cov txheej txheem thiab lwm yam. Cov nram qab no luv luv qhia txog dyeing thiab luam ntawv cov khoom ntawm feem ntau siv dyes rau ntshiab paj rwb ntaub
