Cov teeb meem tshwm sim hauv paj rwb dyeing: Qhov ua rau thiab kev daws teeb meem ntawm dyeing defects

Nyob rau hauv cov txheej txheem dyeing ntaub, xim tsis sib xws yog ib qho tsis xws luag.Thiabdyeingdefect yog ib qho teeb meem dav dav.

Yog vim li cas 1: Pretreatment tsis huv

Kev daws: Kho covkho ua ntejtxheej txheem los xyuas kom meej tias lub pretreatment yog txawm, huv si thiab meej.Xaiv thiab siv cov khoom ua haujlwm zoo tshaj plaws thiab cov emulsifying tus neeg sawv cev kom tsis txhob foaming ua rau dyeing tsis xws luag.

Yog vim li cas 2: Residual hydrogen peroxide tom qab pretreatment

Kev daws: Ntsuas qhov seem hydrogen ua ntej dyeing.Txhim kho cov txheej txheem ntxuav tom qab pretreatment los yog siv cov deoxidant zoo heev tom qab neutralization.Yog tias siv tus neeg ua kom txo qis, thov ua tib zoo saib xyuas qhov cuam tshuam ntawm cov residual txo tus neeg sawv cev ntawm dyeing thaum deoxidizing.

Yog vim li cas 3: Qhov phem compatibility ntawm dyes

Kev daws: Hloov cov dyes.Xaiv cov dyes nrog qis qis qis-hloov tshiab thiab cov cuab yeej tsiv teb tsaws zoo.Xaiv ib pawg dyes uas zoo sib xws dye-hloov tshiab kom phim cov xim.

Yog vim li cas plaub: Qhov ntau npaum thiab ntxiv kev txiav txim ntawm anhydrous sodium sulphate / sodium carbonate

Kev daws: Xaiv cov tshuaj uas tsim nyog ntawm anhydrous sodium sulphate / sodium carbonate raws li cov xim sib txawv.Anhydrous sodium sulphate tuaj yeem muab ntxiv ua ntej lossis tom qab dyes.Yog tias anhydrous sodium sulphate ntxiv ua ntej dyes, thov ntxiv nws ib zaug.Yog tias anhydrous sodium sulphate ntxiv tom qab dyes, nws yuav tsum tau maj mam ntxiv.

Yog vim li cas 5: Tsis zoo ntawm cov dej ntau lawm thiab siab hardness ntawm cov auxiliaries ntxiv

Kev daws: Saib xyuas thiab txheeb xyuas pH tus nqi thiab hardness tsis tu ncua txhua hnub.Siv cov tshuaj pH buffering thiabchelate dispersing tus neeg sawv cevkom neutralize cov dej zoo.

Yog vim li cas 6: Dyeing mob

Kev daws: Kho thiab optimize dyeing txheej txheem.Tswj cov dyeing da dej piv, cua kub ceev, dye-uptake ntawm dyes, dyeing lub sij hawm thiab kev khiav hauj lwm mob ntawm cov khoom, thiab lwm yam.

Hauv cov txheej txheem dyeing, muaj ntau yam cuam tshuam rau cov nyhuv dyeing.Nyob rau hauv ib lo lus, muaj peb yam: pretreatment, dyes thiab dyeing mob.Yog li ntawd, kev paub thiab tswj cov kev cuam tshuam ntawm peb yam no thiab lawv cov kev sib koom ua ke yog txoj hauv kev los tiv thaiv qhov tsis xws luag.
