Dyeing thiab tiav
1.Npuag ua ntej kho Singeing: Hlawv tawm cov fluff ntawm daim ntaub nto kom cov ntaub nto huv si 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 daim ntaub grey thiab ntxiv cov roj nplua nyeem, softeners, thickeners, preservatives, thiab lwm yam., uas yog qhov zoo rau cov tom ntej boiling thiab bleaching ua.
Smelting: tshem tawm cov impurities nyob rau hauv grey fabrics xws li waxy tshuaj, pectin tshuaj, nitrogenous tshuaj thiab ib co roj, thiab lwm yam, kom cov ntaub muaj ib tug tej yam degree ntawm dej nqus, uas yog yooj yim rau lub adsorption thiab diffusion ntawm dyes thaum lub sij hawm luam ntawv. thiab dyeing txheej txheem.
Bleaching: tshem tawm cov pigments ntuj ntawm cov fibers thiab tej yam ntuj tso impurities xws li paj rwb noob hulls, muab cov ntaub qhov tsim nyog whiteness, thiab txhim kho lub brightness thiab dyeing nyhuv ntawm dyeing.
Mercerization: Los ntawm kev kho cov dej qab zib muaj zog, qhov loj me, ruaj khov thiab txhim kho lub peev xwm adsorption rau dyes tau txais, thiab lub cev thiab cov khoom siv xws li lub zog, elongation thiab elasticity tau txhim kho.
2. Hom kev siv dyes
Direct dye: Direct dye yog hais txog cov xim uas tuaj yeem ua kom sov thiab rhaub hauv qhov nruab nrab lossis tsis muaj zog alkaline nruab nrab kom ncaj qha dye paj rwb fibers.Nws muaj qhov ncaj qha ncaj qha rau cellulose fibers, thiab nws tsis tas yuav siv cov dyes cuam tshuam nrog cov txheej txheem tshuaj rau xim fibers thiab lwm yam ntaub ntawv.
Reactive dye: Nws yog cov dej-soluble dye nrog cov active pab pawg nyob rau hauv lub molecule, uas yuav covalently khi nrog cov hydroxyl pawg ntawm cellulose molecules nyob rau hauv weakly alkaline tej yam kev mob.Lub sij hawm nruab hnub nrawm ntawm cov tshuaj dyes feem ntau zoo dua.Tom qab tag nrho ntxuav thiab ntab, soaping ceev ceev thiab rubbing ceev yog siab.
Acid dyes: Nws yog ib hom dej-soluble dyes nrog acidic pawg hauv cov qauv, uas yog dyed nyob rau hauv acidic nruab nrab.Feem ntau ntawm cov kua qaub dyes muaj sodium sulfonate, soluble hauv dej, ci hauv xim thiab ua tiav hauv cov xim spectrum.Nws yog tsuas yog siv rau dyeing ntaub plaub, txhob lo lo ntxhuav thiab nylon, thiab lwm yam. Nws tsis muaj colouring zog rau cellulose fibers.
Vat dyes: Vat dyes yog insoluble hauv dej.Thaum dyeing, lawv yuav tsum tau txo thiab yaj nyob rau hauv ib tug muaj zog alkaline txo cov tshuaj los tsim leuco-chromatic sodium ntsev rau dye fibers.Tom qab oxidation, lawv yuav rov qab mus rau lub pas dej tsis sib haum thiab kho lawv ntawm cov fibers.Feem ntau washable, lub teeb ceev ceev yog siab dua.
Disperse dyes: Disperse dyes muaj cov molecules me thiab tsis muaj dej-soluble pawg hauv cov qauv.Lawv yog uniformly dispersed nyob rau hauv dyeing tov nrog kev pab los ntawm dispersants rau dyeing.Polyester paj rwb dyed nrog disperse dyes tuaj yeem dyed polyester fiber, acetate fiber thiab polyester amine fiber, thiab dhau los ua cov xim tshwj xeeb rau polyester.
Ua tiav
Stretching, weft trimming, shaping, shrinking, whitening, calendering, sanding, raising thiab shearing, txheej, thiab lwm yam.
