Dyeing paj rwb xov nrog Sulfur Dub Hoobkas

Dyeing paj rwb xov paj nrog Sulfur Black yog ib qho kev coj ua, tshwj xeeb tshaj yog rau kev tsim cov xov sib sib zog nqus dub siv hauv denim, hnyav fabrics, thiab workwear. Cov txheej txheem sib txawv me ntsis ntawm dyeing ntaub vim cov xov paj yog nyob rau hauv ib txoj hlua los yog daim ntawv pob, yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev txiav txim siab rau kev nkag mus thiab theem.

1. Txoj kev thov tseem ceeb

Muaj ob txoj hauv kev rau dyeing xov paj nrog Sulfur Black, nyob ntawm seb cov khoom siv thiab qhov kawg siv:

· Pob Dyeing: Cov xov paj raug mob rau hauv cov hlab perforated (pob khoom) thiab muab tso rau hauv lub tshuab dyeing. Cov dej cawv dye yog pumped nyob rau hauv siab los ntawm sab hauv mus rau sab nraud ntawm cov pob khoom. Txoj kev no yuav tsum tau muaj tus nqi ntws siab thiab ceev faj tswj xyuas kom cov cawv nkag mus rau tag nrho cov pob sib npaug. Nws ua haujlwm zoo dua rau cov ntim loj.

· Hank (Skein) Dyeing: Cov xov paj yog looped rau hauv hanks thiab dai rau ntawm ib tug pas nyob rau hauv ib da dej dyeing. Cov cawv yog circulated, thiab cov hanks feem ntau tig. Txoj kev no yog softer thiab tso cai rau kev nkag tau zoo heev, ua rau nws haum rau cov yarns yarns los yog cov uas xav tau ib tug lofty kov. Txawm li cas los xij, nws yog kev ua haujlwm ntau dua - mob hnyav.

2. Cov txheej txheem tseem ceeb rau cov xov paj

Cov chemistry yog tib yam li cov ntaub, tab sis cov neeg kho tshuab kev ua haujlwm yog ua raws li daim ntawv xov paj.

Kev Npaj Cov pob xov paj los yog hanks yuav tsum tau txhuam kom huv si kom tshem tawm cov roj spinning, waxes, thiab av. Qhov no ua kom cov qib dye uptake. Yog tias cov xov paj loj, desizing kuj tseem tsim nyog. Rau pob dyeing, cov pob yuav tsum raug mob rau qhov sib xws (feem ntau 0.35-0.40 g / cm³) kom tso cai rau haus cawv.

Dyeing Lub da dej zas zas yog teem nrog ua ntej-solved Sulfur Black thiab txo tus neeg sawv cev (feem ntau yog Sodium Sulfide lossis ntau dua eco- lwm txoj hauv kev zoo li qabzib nrog dej qab zib caustic).

· Rau Pob Dyeing: Cov dej cawv yog hloov pauv ntawm hauv - mus rau - tawm thiab tawm - mus rau - nyob rau hauv cov nqi ntws siab. Qhov ntsuas kub tau maj mam nce mus rau 90-98℃thiab tuav rau 30-60 feeb, nyob ntawm qhov tob ntawm ntxoov ntxoo thiab pob ntom ntom. Kev nkag mus zoo yog qhov tseem ceeb ntawm no.

· Rau Hank Dyeing: Cov hanks yog submerged thiab maj mam txav mus rau hauv da dej ntawm qhov kub thiab txias kom ntseeg tau tias cov cawv ncav cuag tag nrho cov fibers.

Ntxuav thiab Oxidation Tom qab dyeing, cov xov yog rinsed. Cov xim nyob rau hauv nws daim ntawv soluble yuav tsum tau oxidized los tsim cov xim dub tiag tiag.

· Rau pob dyeing, oxidation feem ntau yog ua los ntawm circulating tus neeg sawv cev oxidizing (xws li hydrogen peroxide lossis sodium perborate) los ntawm cov pob.

· Rau hank dyeing, cov xov paj tuaj yeem raug huab cua (skying) lossis kho hauv chav dej oxidation cais.

Tom qab-Kev Kho Mob Cov kauj ruam no yog qhov tseem ceeb rau Sulfur Black, tshwj xeeb tshaj yog nyob rau hauv cov xov paj uas yuav muab khaws cia rau lub sij hawm ntev los yog woven rau hauv ntaub tom qab.

· Soaping: Tshem tawm cov xim tsis ruaj ntawm qhov chaw.

· Kev tiv thaiv- kev sib tw: Cov xov paj tau kho nrog cov neeg ua haujlwm zoo li Urea lossis Sodium Acetate kom tsis txhob muaj cov kua qaub qaub qaub. Qhov no tiv thaiv cov xov paj los ntawm kev qaug zog thiab nkig dhau sijhawm (ib txheej txheem hu ua kev sib tw). Rau cov xov paj, qhov no yog qhov tseem ceeb heev vim tias qhov kev puas tsuaj yuav tsis pom txog thaum nws tau woven.

· Softening: Ib qho softener feem ntau yog siv rau thaum kawg los lubricate cov xov paj rau cov txheej txheem tom ntej xws li warping thiab weaving, txo kev sib txhuam thiab tawg.

3. Kev txiav txim siab tseem ceeb rau cov xov paj

· Kev nkag mus vs. Nto Dyeing: Hauv pob dyeing, muaj kev pheej hmoo ntawm tsuas yog dyeing txheej txheej ntawm lub pob thaum sab hauv tseem tsis tau dyed ("layering"). Qhov no yuav tsum muaj kev tswj xyuas meej ntawm cov nqi ntws, qhov kub thiab txias gradients, thiab lub sijhawm dyeing kom ntseeg tau tias cov xim tuaj yeem ncav cuag lub hauv paus ntawm lub pob thiab cov tub ntxhais ntawm cov xov paj nws tus kheej.

· Levelness: Tsis sib luag dyeing nyob rau hauv xov paj yuav ua rau pom streaks (warp streaks los yog weft tuav) nyob rau hauv lub kawg woven ntaub. Yog li ntawd, kom ruaj khov thiab zoo ib yam da dej yog qhov tseem ceeb.

· Kev ntub dej nrawm nrawm: Raws li tau hais hauv cov ntsiab lus dhau los, qhov ntub dej nrawm nrawm ntawm Sulfur Black tuaj yeem yog qhov nyuaj. Rau cov xov paj, qhov no yog qhov tseem ceeb vim tias cov xov paj dyed yuav raug kev sib txhuam thaum lub sij hawm xaws. Kev ntxuav kom zoo thiab xab npum yog qhov tseem ceeb kom tshem tawm cov xim pleev xim uas tuaj yeem ua rau xim tsiv teb tsaws lossis tsis zoo ntawm cov ntaub ntub dej hauv cov ntaub kawg.

· Kev pheej hmoo ntawm kev sib tw: Vim tias cov xov paj yog cov khoom nruab nrab, ib qho kev poob qis los ntawm kev dyeing tsis raug lossis tom qab- kev kho mob tsuas yog tshwm sim thaum lub sij hawm siab - kev nyuaj siab ntawm kev xaws, ua rau muaj kev tawg tsis tu ncua. Kev tiv thaiv zoo - kev sib tw kev kho mob tsis yog- sib tham.
