Cov dyes feem ntau muab faib ua pawg hauv qab no: reactive dyes, disperse dyes, direct dyes, vat dyes, sulfur dyes, acid dyes, cationic dyes thiab insoluble azo dyes.
Reactive dyes yog feem ntau siv, uas feem ntau yog siv rau hauv dyeing thiab luam ntawv rau fabrics ntawm paj rwb, viscose fiber, Lyocell, Modal thiabflax.Txhob lo lo ntxhuav, ntaub plaub thiab nylon kuj feem ntau dyed los ntawm reactive dyes.Reactive dyes yog tsim los ntawm peb qhov chaw, raws li niam txiv, pab pawg neeg nquag thiab pab pawg sib txuas.Raws li kev faib tawm ntawm pawg neeg nquag, feem ntau siv yog monochlorotriazine dyes, vinyl sulfone dyes thiab dichlorotriazine dyes, thiab lwm yam. Dichlorotriazine dyes yuav tsum ua haujlwm ntawm chav tsev kub lossis qis dua 40 ℃, uas yog hu ua low temperature dyes.Vinyl sulfone dyes feem ntau ua haujlwm ntawm 60 ℃, uas yog hu ua nruab nrab kub dyes.Monochlorotriazine dyes ua haujlwm ntawm 90 ~ 98 ℃, uas yog hu ua kub kub dyes.Feem ntau ntawm cov dyes siv nyob rau hauv reactive printing yog monochlorotriazine dyes.
Disperse dyes feem ntau siv rau hauv dyeing thiab luam ntawvrau polyester thiab acetate fibers.Cov txheej txheem dyeing rau polyester los ntawm disperse dyes yog kub thiab siab dyeing thiab thermosol dyeing.Vim tias cov cab kuj muaj tshuaj lom, cov kab mob dyeing txoj kev siv tsawg heev tam sim no.Kev kub siab thiab kev kub siab yog siv rau hauv cov pa dyeing thaum jig dyeing thiab thermosol dyeing txheej txheem yog nyob rau hauv padding dyeing.Rau acetate fibers, lawv tuaj yeem dyed ntawm 80 ℃.Thiab rau PTT fibers,muaj peev xwm ua tau zoo heev dye-uptake ntawm 110 ℃.Disperse dyes kuj tseem siv tau los dye nylon hauv lub teeb xim, uas muaj cov nyhuv zoo.Tab sis rau cov xim nruab nrab thiab tsaus nti, cov xim ntxhua khaub ncaws tsis zoo.
Direct dyes tuaj yeem siv rau xim paj rwb, viscose fiber, flax, Lyocell, Modal, silk, wool, soybean protein fiber thiabnylon, thiab lwm yam. Tab sis feem ntau cov xim ceev ceev tsis zoo.Yog li daim ntawv thov hauv paj rwb thiab flax yog nyob rau ntawm qhov txo qis thaum lawv tseem siv dav hauv cov ntaub lo lo ntxhuav thiab ntaub plaub.Direct blends dyes yog qhov kub thiab txias, uas tuaj yeem siv ua ke nrog cov dyes disperse hauv tib da dej kom dye polyester / paj rwb blends lossis intertexture.
Vat dyes feem ntau yog rau paj rwb thiab flax fabrics.Lawv muaj cov xim zoo ceev ceev, xws li ntxuav ceev, hws ceev ceev, lub teeb ceev ceev, rubbing ceev thiab chlorine ceev.Tab sis qee cov dyes yog photosensitive thiab nkig.Lawv feem ntau yog siv rau hauv padding dyeing, uas dyes yuav tsum tau txo kom dyeing thiab ces oxidized.Qee cov dyes tau ua rau cov vat dyes soluble, uas yooj yim rau kev siv thiab kim.
Cationic dyes feem ntau yog siv rau hauv kev tuag thiab luam ntawv rau acrylic fiber thiab cationic hloov polyester.Lub teeb ceev ceev yog qhov zoo heev.Thiab qee cov dyes tshwj xeeb tshaj yog ci.
Sulfur dyes feem ntau yog siv rau paj rwb / flax npuag nrog kev ua haujlwm zoo.Tab sis xim ceev ceev tsis zoo.Qhov khoom siv tau zoo tshaj plaws yog sulfur dub dye.Txawm li cas los xij, muaj qhov tshwm sim ntawm kev khaws cia brittle puas tsuaj.
Acid dyes tau muab faib ua cov kua qaub tsis muaj zog, muaj zog acid dyes thiab nruab nrab dyes, uas yog siv rau hauv cov txheej txheem dyeing rau nylon, silk, wool thiab protein fiber.
Vim muaj teeb meem tiv thaiv ib puag ncig, insoluble azo dyes tam sim no tsis tshua siv.
Ntxiv nrog rau dyes, muaj cov coatings.Feem ntau coatings yog siv rau kev luam ntawv, tab sis kuj rau dyeing.Coatings yog insoluble nyob rau hauv dej.Lawv yog adhered rau saum npoo ntawm fabrics nyob rau hauv qhov kev txiav txim ntawm adhesives.Coatings lawv tus kheej yuav tsis muaj tshuaj tiv thaiv nrog cov ntaub.Txheej dyeing feem ntau yog nyob rau hauv ntev lub tsheb padding dyeing thiab kuj nyob rau hauv lub teeb lub tshuab rau kho xim.Txhawm rau tiv thaiv luam ntawv ntawm cov xim reactive, feem ntau siv cov txheej, thiab ntxiv ammonium sulfate los yog citric acid.
