Aluminium Sulfate, nrog rau cov tshuaj formula Al2 (SO4) 3, tseem hu ua alum, yog ib tug dej-soluble compound uas plays ib tug tseem ceeb luag hauj lwm nyob rau hauv textile manufacturing txheej txheem vim nws cov khoom tshwj xeeb thiab tshuaj muaj pes tsawg leeg. Ib qho ntawm nws cov kev siv tseem ceeb yog dyeing thiab luam ntawv ntawm cov ntaub. Aluminium sulfate ua raws li ib tug mordant, uas yuav pab kho dyes rau cov fibers, yog li ua kom cov xim ceev ceev thiab txhim kho tag nrho cov zoo ntawm dyed ntaub. Los ntawm kev tsim cov complexes insoluble nrog cov dyes, alum xyuas kom lawv tuav ntawm cov ntaub, tiv thaiv los ntshav thiab fading thaum lub sij hawm tom ntej ntxuav.
Ntxiv mus, aluminium sulfate yog siv nyob rau hauv kev npaj ntawm tej yam mordant dyes, xws li qaib ntxhw liab roj. Cov dyes, paub txog lawv cov xim zoo nkauj thiab ntev ntev, yog dav siv hauv kev lag luam textile rau dyeing paj rwb thiab lwm yam ntuj fibers. Qhov sib ntxiv ntawm alum rau cov dye da dej pab txhawb kev khi ntawm cov xim molecules rau cov ntaub, uas ua rau cov xim tsis sib xws thiab txhim kho kev ntxuav ceev.
Ntxiv nrog rau nws lub luag haujlwm hauv dyeing, aluminium sulfate pom daim ntawv thov hauv textile sizing, txheej txheem tsom rau kev txhim kho lub zog, smoothness, thiab tuav cov khoom ntawm yarns thiab fabrics. Sizing agents, feem ntau muaj cov hmoov txhuv nplej siab los yog hluavtaws polymers, yog siv rau saum npoo ntawm yarns kom txo tau kev sib txhuam thiab tawg thaum lub sij hawm weaving los yog knitting. Aluminium sulfate yog siv los ua coagulant hauv kev npaj cov hmoov txhuv nplej siab raws li cov qauv tsim. Los ntawm kev txhawb kev sib sau ua ke ntawm cov hmoov txhuv nplej siab, alum pab kom ua tiav cov khoom sib txawv ntawm cov ntaub, ua rau kev txhim kho kev ua haujlwm ntawm cov ntaub thiab cov ntaub zoo.
Tsis tas li ntawd, aluminium sulfate yog ua haujlwm nyob rau hauv scouring thiab desizing ntawm textiles, tshwj xeeb tshaj yog paj rwb fibers. Scouring yog cov txheej txheem ntawm kev tshem tawm impurities, xws li waxes, pectins, thiab natural oils, los ntawm cov ntaub nto los pab kom zoo dua dye nkag mus thiab adhesion. Aluminium sulfate, nrog rau alkalis los yog surfactants, pab nyob rau hauv emulsifying thiab dispersing cov impurities, ua rau kom huv si thiab ntau absorbent fibers. Ib yam li ntawd, nyob rau hauv desizing, alum pab nyob rau hauv kev puas tsuaj ntawm cov hmoov txhuv nplej siab raws li sizing tus neeg ua ntawv thov thaum lub sij hawm npaj yarn, yog li npaj cov ntaub rau tom ntej dyeing los yog tiav kev kho mob.
Tsis tas li ntawd, aluminium sulfate ua haujlwm ua cov coagulant hauv kev kho cov dej khib nyiab hauv cov chaw tsim khoom siv textile. Cov effluent tsim los ntawm ntau yam kev lag luam textile feem ntau muaj cov khib nyiab tshem tawm, cov xim pleev xim, thiab lwm yam pa phem, ua rau muaj teeb meem ib puag ncig yog tias tsis kho. Los ntawm kev ntxiv alum rau cov dej khib nyiab, cov khoom raug tshem tawm yog destabilized thiab agglomerated, pab lawv tshem tawm los ntawm sedimentation los yog pom. Qhov no pab ua kom tau raws li cov qauv kev tswj hwm thiab txo qis ib puag ncig kev cuam tshuam ntawm cov khoom siv textile.
Hauv kev xaus, aluminium sulfate plays lub luag haujlwm ntau yam hauv kev lag luam textile, pab rau dyeing, sizing, scouring, desizing, thiab cov txheej txheem dej khib nyiab. Nws cov txiaj ntsig zoo li mordant, coagulant, thiab kev pabcuam ua haujlwm underscores nws qhov tseem ceeb hauv kev lag luam textile.
