Tag nrho cov txheej txheem los ntawm xov paj mus rau weaving thiab dyeing
Kev kho mob ua ntej ntawm daim ntaub tsis zoo
Singeing: Hlawv tawm cov fluff ntawm daim ntaub nto kom ua rau saum npoo ntawm daim ntaub du thiab zoo nkauj, thiab tiv thaiv tsis sib xws dyeing los yog luam ntawv tsis xws luag vim muaj fluff thaum lub sij hawm dyeing los yog luam ntawv.
Desizing: Tshem tawm qhov loj ntawm cov ntaub grey thiab cov roj nplaum ntxiv, softener, thickener, preservative, thiab lwm yam, yog qhov zoo rau cov txheej txheem tom qab scouring thiab bleaching.
Scouring: Tshem tawm cov khoom tsis huv xws li cov khoom siv quav ciab, cov tshuaj pectin, cov tshuaj muaj nitrogen thiab qee cov roj hauv cov ntaub grey, kom cov ntaub muaj qee yam dej nqus, uas yooj yim rau kev nqus thiab diffusion ntawm dyes thaum luam ntawv thiab dyeing. txheej txheem.
Bleaching: tshem tawm cov impurities xws li ntuj pigments thiab paj rwb husks ntawm fibers, imparts qhov tsim nyog whiteness rau ntaub, thiab txhim kho vividness thiab nyhuv ntawm dyeing.
Mercerizing: Los ntawm kev kho cov dej qab zib ua kom muaj zog, qhov loj me, ruaj khov yog tau, thiab lub peev xwm adsorption ntawm dyes tau txhim kho, thiab cov khoom siv lub cev thiab cov khoom siv xws li lub zog, txuas ntxiv dag zog thiab elasticity tau txhim kho.
Hom uas nquag siv dyes
Direct dye: Direct dye yog hais txog cov xim uas tuaj yeem ncaj qha dye paj rwb fibers los ntawm cua sov thiab boiling nyob rau hauv nruab nrab los yog tsis muaj zog alkaline nruab nrab. Nws muaj kev ncaj ncees rau cov cellulose fibers, thiab tsis tas yuav siv cov dyes ntsig txog cov txheej txheem tshuaj rau xim fibers thiab lwm yam ntaub ntawv.
Reactive dye: Nws yog dej-soluble dye nrog active pab pawg nyob rau hauv lub molecule, uas yuav covalently khi nrog cov hydroxyl pab pawg neeg ntawm cellulose molecule nyob rau hauv tsis muaj zog alkaline tej yam kev mob. Kev ceev ceev txhua hnub ntawm reactive dyes feem ntau zoo, thiab soaping fastness thiab rubbing ceev yog siab dua tom qab ntxuav txaus thiab ntab.
Acid dyes: Nws yog ib hom dej-soluble dyes nrog acidic pawg ntawm cov qauv, uas yog dyed nyob rau hauv acidic nruab nrab. Feem ntau ntawm cov kua qaub dyes muaj sulfonic acid sodium ntsev, uas yog soluble hauv dej, ci hauv xim thiab ua tiav hauv chromatogram. Nws yog tsuas yog siv rau dyeing ntaub plaub, txhob lo lo ntxhuav thiab nylon, thiab tsis muaj colouring zog rau cellulose fibers.
Vat dyes: Vat dyes yog insoluble hauv dej. Thaum dyeing, lawv yuav tsum tau txo thiab yaj rau hauv leuco sodium ntsev nyob rau hauv ib qho alkaline muaj zog txo cov tshuaj rau dye fibers. Tom qab oxidation, lawv yuav rov qab los rau hauv cov pas dej tsis sib haum thiab ruaj khov ntawm cov fibers. Feem ntau, qhov ceev ceev rau kev ntxuav thiab lub teeb nrawm yog siab.
Disperse dyes: Disperse dyes muaj cov molecules me me thiab tsis muaj cov dej-soluble pawg hauv cov qauv. Lawv yog uniformly dispersed nyob rau hauv dye tov nrog kev pab los ntawm dispersants rau dyeing. Cov polyester thiab paj rwb dyed nrog disperse dyes tuaj yeem dyed nrog polyester fiber, acetate fiber thiab polyester amine fiber, thiab dhau los ua cov xim tshwj xeeb rau polyester.
