Tshem tawm cov paj rwb thiab lwm yam cellulosic fibers

Scouring yog txheej txheem ntub dej tseem ceeb tshaj plaws siv rau cov ntaub ntawv textile ua ntej dyeing lossis luam ntawv.Nws feem ntau yog txheej txheem ntxuav uas txawv teb chaws lossis impurities raug tshem tawm.Cov txheej txheem scouring, thaum purifying α-cellulose, imparts lub cim hydrophilic thiab permeability tsim nyog rau cov txheej txheem tom ntej (bleaching, mercerizing, dyeing los yog luam ntawv).Kev ua haujlwm zoo yog lub hauv paus ntawm kev ua tiav tiav.Kev ua tau zoo ntawm cov txheej txheem scouring yog txiav txim los ntawm kev txhim kho hauv wettability ntawm cov khoom scoured.

Tshwj xeeb tshaj yog, scouring yog ua los txhawm rau txhawm rau tshem tawm cov roj tsis xav tau, rog, waxes, soluble impurities thiab cov khoom siv los yog cov av uas ua rau cov fibers, uas yuav txwv tsis pub dyeing, luam ntawv thiab ua tiav cov txheej txheem.Cov txheej txheem tseem ceeb yog kev kho mob nrog xab npum lossis tshuaj ntxuav tes nrog lossis tsis muaj alkali ntxiv.Nyob ntawm seb hom fiber ntau, alkali yuav tsis muaj zog (xws li dej qab zib tshauv) lossis muaj zog (caustic soda).

Thaum siv xab npum, yuav tsum muaj cov dej mos zoo.Cov hlau ion (Fe³⁺thiab Ca²⁺) tam sim no nyob rau hauv dej tawv thiab pectin ntawm paj rwb tuaj yeem tsim cov xab npum insoluble.Qhov teeb meem yog mob heev thaum scouring yog nqa tawm nyob rau hauv ib tug tas mus li txheej txheem uas muaj ib tug padding da dej qhov twg cov cawv feem ntau qis dua nyob rau hauv batch txheej txheem;cov chelating los yog sequestering tus neeg saib xyuas, xws li Ethylenediaminetetraacetic acid (EDTA), Nitrilotriacetic acid (NTA), thiab lwm yam, tej zaum yuav raug siv los tiv thaiv scum thiab zaj duab xis tsim.Cov khoom siv hluavtaws zoo zoo muab qhov sib npaug zoo nrog ntub dej, ntxuav, emulsifying, dispersing thiab foaming zog, yog li muab kev tu zoo.Anionic, non-ionic detergents lossis lawv cov khoom sib xyaw, cov kuab tshuaj uas siv tshuaj ntxuav tes thiab xab npum feem ntau yog siv rau kev txhuam.Rau kev ua kom cov txheej txheem scouring nrawm, cov neeg ua dej ntub dej ua ke nrog cov kuab tshuaj kub npau npau (cyclohexanol, methylcyclohexanol, thiab lwm yam) qee zaum siv, tab sis cov txheej txheem yuav tsis yog eco-friendly.Kev ua haujlwm ntawm cov kuab tshuaj feem ntau yog ua kom yaj cov rog tsis txaus thiab waxes.

Cov neeg tsim khoom tau ntxiv rau hauv kier-boiling da dej txhawm rau txhawm rau ua kom muaj cov tshuaj ntxuav tes los yog tshuaj ntxuav tes.Cov no feem ntau yog ntsev xws li borates, silicates, phosphates, sodium chloride los yog sodium sulphate.Sodium metasilicate (Na₂SiO₃, 5 H ua₂O) tuaj yeem ua tau raws li cov tshuaj ntxuav tes thiab tsis pub.Lub luag haujlwm ntawm qhov tsis yog tsav cov xab npum los ntawm cov dej theem mus rau cov ntaub / dej sib txuas thiab yog li ua kom cov tshuaj xab npum ntawm cov ntaub.

Thaum lub sij hawm boiling ntawm paj rwb nrog caustic soda, cua nkag yuav ua rau oxidation ntawm cellulose.Qhov no yuav tiv thaiv tau los ntawm kev ntxiv cov tshuaj txo qis xws li sodium bisulphite lossis txawm tias hydrosulphite hauv cov cawv cawv.

Cov txheej txheem scouring rau cov ntaub ntawv textile sib txawv sib txawv.Ntawm cov fibers ntuj, cov paj rwb nyoos muaj nyob rau hauv daim ntawv ntshiab tshaj plaws.Tag nrho cov impurities yuav raug tshem tawm yog tsawg dua 10% ntawm tag nrho qhov hnyav.Txawm li cas los xij, lub sijhawm kub kub yog qhov tsim nyog vim tias paj rwb muaj cov waxes ntawm qhov hnyav molecular, uas nyuaj rau tshem tawm.Cov proteins kuj nyob rau hauv lub hauv paus kab noj hniav ntawm cov fiber (lumen) uas yog ib tug kuj siv tsis tau rau cov tshuaj siv nyob rau hauv scouring.Hmoov zoo, cellulose tsis cuam tshuam los ntawm kev kho mob ntev nrog cov tshuaj caustic mus txog qhov concentration ntawm 2% thaum tsis muaj huab cua.Yog li ntawd, nws muaj peev xwm hloov tau tag nrho cov impurities thaum lub sij hawm scouring, tshwj tsis yog tej yam ntuj tso xim teeb meem, mus rau hauv daim ntawv soluble, uas yuav tsum tau ntxuav tawm nrog dej.

Kev txhuam cov cellulosic fibers uas tsis yog paj rwb yog qhov yooj yim heev.Bast fibers zoo li jute thiab fl ax yuav tsis tuaj yeem raug scoured ntau vim muaj feem yuav raug tshem tawm ntawm ntau yam tsis-fibrous nrog rau qhov kev puas tsuaj ntawm cov khoom.Cov no feem ntau scoured siv xab npum los yog xab npum nrog rau dej qab zib tshauv.Jute feem ntau siv yam tsis muaj kev lim dej ntxiv, tab sis fl ax thiab ramie feem ntau yog scoured thiab feem ntau bleached.Jute rau dyeing yog pre-scoured tab sis ntau npaum li cas ntawm lignin nyob twj ywm, ua rau tsis zoo lub teeb-ceev ceev.

Txij li thaum ntuj impurities xws li paj rwb wax, pectic tshuaj thiab cov protein muaj feem xyuam rau hauv lub hauv paus phab ntsa, cov txheej txheem scouring aims tshem tawm cov phab ntsa.
