Txoj kev zoo tshaj los luam tawm ntawm ntaub

Ua ntej

1. Thaiv cov fiber ntau capillary, txo cov nyhuv capillary ntawm fiber ntau, tiv thaiv cov dye los ntawm kev luam tawm ntawm cov ntaub, thiab tau txais cov qauv meej.

2. Cov additives hauv slurry tuaj yeem txhawb kev sib xyaw ntawm cov dye thiab fiber ntau hauv lub xeev kub thiab av noo kom tau txais qee qhov xim qhov tob thiab xim ceev ceev.

3. Tom qab sizing, nws muaj peev xwm daws tau cov teeb meem ntawm cov ntaub curling thiab wrinkling, txhim kho cov ntaub ntawv zoo, thiab tiv thaiv lub nozzle los ntawm kev puas tsuaj los ntawm qhov tsa ib feem ntawm cov ntaub vim cov ntaub tsis sib xws. 4. Tom qab sizing, cov ntaub yuav tawv, ua rau nws yooj yim rau lub tshuab luam ntawv pub cov ntaub.

Npaj slurry

Muaj pes tsawg leeg ntawm slurry: muab tshuaj txhuam, alkaline tus neeg sawv cev (baking soda), sodium sulfate, urea, sodium hexametaphosphate. Txoj kev npaj: ntxiv txhua yam tshuaj thiab muab tshuaj txhuam rau hauv dej deionized hauv ib qho kev faib ua feem, thiab tom qab ntawd do sai nrog lub tov khoom kom txog thaum tsis muaj cov khoom nyob hauv slurry. Qhov kev txiav txim ntawm kev ntxiv cov khoom:

Sodium hexametaphosphate - Yuanming hmoov - urea - muab tshuaj txhuam - baking soda

Lub luag haujlwm ntawm ntau yam khoom hauv slurry

Sodium hexametaphosphate: chelate hlau ions hauv dej, xws li calcium ions, magnesium ions, thiab lwm yam., kom muag dej zoo

Urea: Hygroscopic thiab solubilizing, nws tuaj yeem txhawb kev nthuav dav fiber ntau thaum lub sij hawm steaming, thiab pab dyes kom yaj tag, uas yog qhov zoo rau kev nkag mus thiab cov tshuaj tiv thaiv ntawm dyes rau hauv cov fiber ntau. Sodium sulfate: Thaum dyeing cellulose fibers (paj rwb, linen, thiab lwm yam) fabrics, sodium sulfate (sodium sulfate) feem ntau yog siv los ua dyeing accelerator. Sodium sulfate tuaj yeem txo qhov solubility ntawm dyes hauv da dej thiab txhim kho kev siv cov dyes. Alkaline tus neeg sawv cev (baking soda): Thaum steaming, qib ntawm ionization ntawm cellulose fiber ntau yog nce, kom cov fiber ntau thiab cov reactive dye yog valence bonded. Paste: Lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv cov dye los ntawm permeating ntawm cov ntaub. Hom muab tshuaj txhuam thiab cov qauv molecular muaj qhov sib txawv inhibitory cuam tshuam ntawm cov xim, uas yuav cuam tshuam rau cov xim yield, luam ntawv nkag mus thiab pom meej tom qab luam ntawv. Qhov tsim nyog muab tshuaj txhuam yuav tsum tau xaiv raws li cov ntaub thiab hom dye.

Fabric Sizing

Qhov sizing ntawm cov ntaub yog muab faib ua ib sab sizing thiab ob sab sizing. Qhov ib sab sizing yog dhau los ntawm kev tshuaj ntsuam teb los yog lub tshuab luam ntawv tiaj tus lossis lub tshuab txheej txheej, thiab qhov loj me yog sib npaug ntawm cov ntaub los ntawm lub siab ntawm cov pas nrig sib nqus lossis scraper los ntawm qhov screen. Ob chav sided sizing kuj yog padding sizing (qhov seem ntawm 80 feem pua ​​-90 feem pua), uas yog nyem cov slurry mus rau hauv cov ntaub los ntawm ib lub tsheb dov, thiab kuj yuav siv tau nyob rau hauv ob-sided sizing txheej txheem ntawm digital. luam ntawv los ntawm kev hloov kho lub tshuab stenter. .

Cov teeb meem uas yuav tsum tau them sai sai rau hauv sizing

1. Ua tib zoo saib xyuas qhov teeb meem ntawm cov ntaub ntawm cov ntaub thaum sizing. Thaum lub weft ntawm cov ntaub yog skewed, cov ntaub yuav tsis raug nteg nyob rau hauv txoj siv txoj siv nyob rau hauv lub tom ntej printing txheej txheem, uas ua rau unevenness, uas yog ib qho yooj yim mus rub lub nozzle, cuam tshuam qhov zoo ntawm tus qauv thiab kev pab cuam lub neej ntawm cov ntaub. nozzle. .

2. Cov ntaub tom qab sizing yuav tsum tau muab kaw thiab khaws cia rau hauv lub sijhawm kom tsis txhob muaj qhov sib faib ntawm cov slurry Cheebtsam los ntawm kev hloov thiab deteriorating vim qhov nqus ntawm noo noo thiab lwm yam khoom hauv huab cua, uas yuav ua rau muaj teeb meem xws li los ntshav ntawm tus qauv lossis tsis txaus. xim tob thaum luam ntawv.
