CMC siv hauv Textile thiab Dyeing kev lag luam

Carboxymethylcellulose (CMC) yog dav siv nyob rau hauv textile thiab dyeing kev lag luam rau nws ntau yam khoom raws li ib tug dej-soluble polymer. Nws yog muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag, los ntawm ib tug tshuaj hloov txheej txheem uas qhia carboxymethyl pawg. CMC pom ntau yam kev siv hauv textile ua thiab dyeing. Nov yog qee qhov kev siv tseem ceeb ntawm CMC hauv kev lag luam textile thiab dyeing:

1. Textile Sizing:
   • CMC yog siv los ua tus neeg sawv cev sizing hauv textile manufacturing. Nws muab cov khoom tsim nyog rau cov xov paj thiab cov ntaub, xws li nce smoothness, txhim kho lub zog, thiab zoo dua rau kev puas tsuaj. CMC yog siv rau warp yarns los pab txhawb lawv txoj kev hla lub loom thaum lub sij hawm weaving.
2. Printing Paste Thickener:
   • Hauv textile printing, CMC ua hauj lwm ua ib lub thickener rau luam pastes. Nws txhim kho cov viscosity ntawm paste, tso cai rau kev tswj kom zoo dua ntawm cov txheej txheem luam ntawv thiab ua kom cov qauv ntse thiab cov qauv zoo ntawm cov ntaub.
3. Dyeing Assistant:
   • CMC yog siv los ua tus pab dyeing hauv cov txheej txheem dyeing. Nws pab txhim kho qhov sib npaug ntawm cov xim nkag mus rau hauv cov fibers, txhim kho cov xim sib xws hauv cov khoom siv dyed.
4. Dispersant rau Pigments:
   • Hauv cov xim luam ntawv, CMC ua haujlwm raws li cov khoom tawg. Nws pab disperse pigments tusyees nyob rau hauv lub luam ntawv muab tshuaj txhuam, kom ntseeg tau tias uniform xim tis ntawm cov ntaub thaum lub sij hawm luam ntawv.
5. Fabric Sizing thiab Finishing:
   • CMC yog ua haujlwm nyob rau hauv cov ntaub sizing los txhim kho cov smoothness thiab tuav ntawm cov ntaub. Nws tseem tuaj yeem siv rau hauv cov txheej txheem tiav los muab qee yam khoom rau cov ntaub ntawv tiav, xws li softness lossis dej repellency.
6. Anti-Back Staining Agent:
   • CMC yog siv los ua cov tshuaj tiv thaiv rov qab staining hauv kev ua denim. Nws tiv thaiv indigo dye los ntawm redepositing rau ntawm ntaub thaum ntxuav, pab tswj cov yam xav tau ntawm denim garments.
7. Emulsion Stabilizer:
   • Nyob rau hauv emulsion polymerization txheej txheem rau textile coatings, CMC yog siv raws li ib tug stabilizer. Nws pab stabilize lub emulsion, ua kom cov txheej txheej ntawm cov ntaub thiab muab cov khoom xav tau xws li dej los yog nplaim taws.
8. Printing ntawm Synthetic Fibers:
   • CMC yog siv hauv kev luam ntawv ntawm cov hluavtaws fibers. Nws pab kom ua tiav cov xim zoo, tiv thaiv los ntshav, thiab ua kom cov adhesion ntawm dyes los yog pigments rau hluavtaws fabrics.
9. Xim Retention Agent:
   • CMC tuaj yeem ua tus neeg saib xyuas xim hauv cov txheej txheem dyeing. Nws pab txhim kho colourfastness ntawm dyed fabrics, pab kom lub neej ntev ntawm cov xim.
10. Xov Paj Lubricant:
    • CMC yog siv los ua cov xov paj roj hmab hauv cov txheej txheem spinning. Nws txo cov kev sib txhuam ntawm cov fibers, ua kom yooj yim rau kev sib tw ntawm cov xov paj thiab txo qis kev tawg.
11. Stabilizer rau Reactive Dyes:
    • Hauv reactive dyeing, CMC tuaj yeem ua haujlwm ua tus stabilizer rau reactive dyes. Nws pab txhim khu kev ruaj ntseg ntawm cov xim da dej thiab txhim kho qhov kho ntawm dyes rau fibers.
12. Txo Fiber-rau-hlau Friction:
    • CMC yog siv los txo kev sib txhuam ntawm fibers thiab hlau nto hauv cov khoom siv textile, tiv thaiv kev puas tsuaj rau fibers thaum lub sij hawm kho tshuab.

Hauv cov ntsiab lus, carboxymethylcellulose (CMC) yog cov khoom muaj txiaj ntsig zoo hauv kev lag luam textile thiab dyeing, pab txhawb rau ntau yam txheej txheem xws li sizing, luam ntawv, dyeing, thiab xov. Nws cov dej-soluble thiab rheological zog ua rau nws muaj ntau yam hauv kev txhim kho kev ua tau zoo thiab cov tsos ntawm textiles.
