The whole process from yarn to weaving and dyeing

Los ntawm xov paj mus rau ntaub

Warping txheej txheem

Hloov cov xov paj qub (pob xov paj) rau hauv cov xov paj warp los ntawm tus ncej.

txheej txheem sizing

Lub cilia ntawm thawj cov xov paj yog compressed los ntawm slurry, thiaj li hais tias lub cilia tsis nias ntawm lub loom vim kev sib txhuam.

Reeding txheej txheem

Lub warp yarn yog muab tso rau ntawm lub reed ntawm ib lub loom thiab siv rau weaving qhov xav tau qhov dav thiab warp ceev.

Dyeing txheej txheem

Cov ntaub tsis zoo pretreatment

Hu nkauj: tshem tawm cov fluff los ntawm daim ntaub nto kom cov ntaub nto ci thiab huv si thiab zoo nkauj, thiaj li 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 daim ntaub grey thiab ntxiv cov roj nplua nyeem, softener, thickener, preservative, thiab lwm yam, uas yog qhov zoo rau cov txheej txheem tom qab scouring thiab bleaching.

Souring: tshem tawm lub ntuj impurities ntawm daim ntaub grey, xws li siv quav ciab, pectin, nitrogen-muaj tshuaj thiab qee cov roj ua haujlwm, kom cov ntaub muaj qee yam dej nqus, uas yooj yim rau kev nqus thiab diffusion ntawm dyes hauv kev luam ntawv thiab dyeing txheej txheem.

Kev tshuaj dawb:tshem tawm cov xim ntuj, paj rwb plhaub thiab lwm yam impurities ntawm cov fiber ntau, muab cov ntaub nrog qhov tsim nyog whiteness, thiab txhim kho lub ci ci thiab dyeing nyhuv ntawm dyeing.

Mercerization: los ntawm kev kho cov dej qab zib ua kom muaj zog, nws tuaj yeem tau txais qhov loj me, ruaj khov luster, txhim kho lub peev xwm adsorption ntawm dyes, thiab txhim kho lub cev thiab txhua yam khoom xws li lub zog, elongation thiab elasticity.

Hom tshuaj dyes

Direct dye: Direct dye yog hais txog ib hom dye uas tuaj yeem ncaj qha dye paj rwb fiber ntau los ntawm cua sov thiab boiling hauv nruab nrab lossis tsis muaj zog alkaline nruab nrab. Nws muaj kev ncaj ncees rau cellulose fibers thiab tsis tas yuav siv cov dyes uas tuaj yeem xim fibers thiab lwm yam ntaub ntawv los ntawm cov txheej txheem tshuaj.

Reactive dye: nws yog dej-soluble dye. Nws cov molecules muaj cov pab pawg nquag, uas tuaj yeem sib cog lus nrog hydroxyl pawg ntawm cellulose molecules nyob rau hauv tsis muaj zog alkaline tej yam kev mob. Reactive dyes feem ntau muaj qhov nrawm nrawm rau hnub ci. Tom qab tag nrho ntxuav thiab ntab, lawv muaj soaping ceev ceev thiab rubbing ceev.

Acid dye: nws yog ib hom dej-soluble dye nrog acid pawg hauv cov qauv. Nws yog dyed nyob rau hauv acid nruab nrab. Feem ntau cov kua qaub dyes muaj sodium sulfonate, uas tuaj yeem yaj hauv dej, nrog cov xim ci thiab ua tiav chromatography. Nws yog tsuas yog siv rau dyeing ntaub plaub, txhob lo lo ntxhuav thiab nylon. Nws tsis muaj xim muaj 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 hauv alkaline muaj zog txo cov tshuaj ua ntej dyeing cov fiber. Tom qab oxidation, lawv rov qab mus rau lub pas dej uas tsis muaj dej tsis zoo thiab raug kho rau ntawm fiber ntau. Feem ntau, lawv muaj kev ntxhua khaub ncaws siab thiab hnub ci ceev.

Disperse dyestuff: disperse dyestuff muaj me me molecules thiab tsis muaj dej-soluble pawg nyob rau hauv nws cov qauv. Nws yog uniformly dispersed nyob rau hauv dye tov nrog kev pab los ntawm dispersant. Polyester paj rwb dyed nrog disperse dyes tuaj yeem dyed nrog polyester fiber, acetate fiber thiab polyester amine fiber, dhau los ua cov xim tshwj xeeb rau polyester.
