1. Cov xim tshwj xeeb
Cov xim ntawm cov xov paj spun yog fiber ntau melange style, uas txawv ntawm cov ntshiab dyeing ntawm natural yarn los yog natural fabric. Cov khoom siv raw ntawm cov xim spinning muaj tsawg kawg yog ib hom xim fiber ntau, uas yog tsim los ntawm tag nrho kev sib xyaw ntawm fibers ntawm cov xim sib txawv hauv spinning. Yog li ntawd, cov ntaub muaj xws li dyed yarn tuaj yeem nthuav tawm cov nyhuv ntawm "spatial mixing" thiab muaj kev hloov ntawm txheej.
2. Cov pa roj carbon tsawg thiab kev tiv thaiv ib puag ncig
Dyed spinning thim rov qab cov tsoos spinning thiab ces dyeing txheej txheem, uas yog dye cov fibers ua ntej, thiab ces muab sib tov thiab tig. Txawm li cas los xij, feem ntau ntawm cov khoom siv fiber ntau tsis yog txhua qhov dyed fibers, thiab 40% -50% ntawm cov ntaub ntawv raw ntawm cov xov paj dyed yog ntuj fibers, thiab tsuas yog ib feem ntawm cov dyeing yog siv. Yog li ntawd, nws yog ib tug kuj ntau zog-txuag thiab ib puag ncig tus phooj ywg.
Ntuj fiber ntau muaj ob txoj haujlwm ua raw khoom rau xim spinning: ib qho yog xim (dawb); Qhov thib ob yog kho qhov tob ntawm tag nrho cov xim spinning khoom.
Piv txwv li, cov paj rwb uas muaj xim zoo nkauj thiab linen grey yarn feem ntau suav txog li 10% ntawm cov paj rwb dyed, uas yog, li ntawm 90% ntawm cov paj rwb fibers yog undyed thiab ntuj.
Tshwj xeeb, yog cov xim fibers hauv cov xov paj-dyed cov khoom yog cov tshuaj fibers, ces nws cov txheej txheem tsim khoom tuaj yeem ua kom tsis muaj pa phem. Piv txwv li, qee cov xim chemical fibers siv "dope coloring" thev naus laus zis los ntxiv cov masterbatches hauv cov txheej txheem spinning, thiab cov txheej txheem ntau lawm yog tsis muaj kuab paug thiab xoom-emission.
3. Dyeing zoo
Cov txheej txheem "spinning thawj zaug thiab tom qab ntawd dyeing", vim tias muaj cov tshuaj sib txawv, ua rau cov fiber ntau dyeing kev ua tau zoo sib txawv, uas ua rau muaj teeb meem rau dyeing ntawm xov paj thiab ntaub tom qab sib tov. Cov xim spinning txais cov txheej txheem ntawm "dyeing ua ntej, ces spinning", uas tsuas yog daws qhov teeb meem ntawm cov xim txuam ntawm heterosexual fiber blending.
Vim hais tias cov txheej txheem dyeing yog hais txog cov txheej txheem ua ntej spinning, tsis muaj teeb meem dab tsi ntawm cov khoom siv fiber ntau: natural, recycled, hluavtaws; Tsis muaj teeb meem dab tsi ntawm cov txheej txheem dyeing yuav tsum tau: high-temperature thiab high-pressure dyeing, los yog kub thiab siab dyeing; Txawm hais tias hom dye: reactive, dispersed, ncaj qha, txo ......, lawv tuaj yeem tawg ib tus zuj zus, dyed cais thiab tom qab ntawd ua ke zoo kawg nkaus. Yog li ntawd, dyeing multi-material blended khoom yog tsis nyuaj.
