I. Pretreatment
1. Blanching/Bleaching:
Ntxiv cov roj nplua nyeem (xws li cov tshuaj pleev xim) kom txo tau cov ntaub sib txhuam thiab tiv thaiv cov kab nrib pleb, tshwj xeeb tshaj yog rau cov paj rwb nyias hauv qab 150 grams.
Muab cov ntaub qhwv yob rau hauv lub dyeing vat, ntxiv auxiliaries raws li qhov hnyav, kom ntseeg tau tias txawm nkag mus.
2. Kev ntxuav thiab ntxuav:
Cov auxiliaries residual raug tshem tawm los ntawm kev ntxuav dej txias siv CCR.
Residual alkali yog neutralized nrog acetic acid los kho tus nqi pH.
II. Dyeing theem
1. Pub thiab cua sov:
Cov dye yuav tsum tau muab sib xyaw kom huv si hauv qhov chaw pabcuam vat thiab yaj tag ua ntej muab ntxiv rau lub vat loj.
Cov cua kub yuav tsum tau tswj nruj me ntsis: cov xim reactive yuav tsum tau khaws cia ntawm 60 degree, thiab polyester ntawm 125℃lossis siab dua, nrog qhov kub thiab txias tsis tshaj 0.5℃ib feeb.
Nws raug nquahu kom nruab lub koob yees duab ntawm cov ntaub conveyor yeeb nkab los saib xyuas cov ntaub sib xws hauv lub sijhawm.
2. Kev nkag mus thiab nkag mus:
Cov ntaub nkag mus rau hauv cov xim da dej hauv ib txoj hlua-zoo li daim ntawv los ntawm cov raj qhia, nrog kwv yees li 2/3 submerged hauv cov dej cawv. Cov ntaub uas tseem tshuav ntab saum npoo av thiab ncig, nrog rau txhua lub sij hawm nyob rau 3-4 feeb.
Segmented kub tswj yog ua haujlwm. Reactive dyes yuav tsum tau qis - kub dyeing ntawm 60℃, thaum polyester yuav tsum tau siab - kub, siab - kev kho mob siab ntawm 125-130℃.
III. Tom qab-kev kho mob
1. Kev kho xim:
Kev kho xim ntawm 80℃rau 20 feeb txhim kho xim nrawm.
Cov ntaub paj rwb yuav tsum muaj ob chav da dej kub sib law liag: thawj qhov nruab nrab nrog acetic acid, tom qab ntawd boiling ob zaug hauv 95℃alkaline dej.
2. Ntxuav thiab Soaping:
Cov dej cawv uas seem raug tshem tawm sai sai uas siv lub tshuab ntxhua khaub ncaws.
Kev ntxuav cov kua qaub thiab ob lub xab npum ntxuav yog ua tiav (cov dej kub los ntawm lub tank auxiliary), tom qab ntawd los ntawm kev ntxuav dej kub zaum kawg.
IV. Cov Ntsiab Cai Tswjfwm
Temperature Gradient: Kev tswj kom meej yog yuav tsum tau zam kom tsis txhob muaj teeb meem xws li kev faib xim tsis sib xws thiab cov cim "nqaij qaib".
Liquor Ratio: Siab-kub, siab-siab hom cawv piv 1:5-1:10; chav-kub hom cawv piv txawm qis dua.
Cov khoom siv xaiv: Cov kav dej- hom siab- qhov kub thiab txias, siab - cov xovxwm siab muaj 20% siab dua lub peev xwm thauj khoom thiab tsim nyog rau cov khoom siv hluavtaws; chav- kub hom yog haum rau ntuj fibers xws li paj rwb thiab linen.
V. Tej teeb meem thiab kev daws teeb meem
Xim Variation: Xyuas seb cov xim puas tau yaj tag thiab yog tias qhov kub thiab txias siab dhau lawm.
Nqaij qaib Claw Marks: Xyuas kom cov roj nplua nyeem txaus ntxiv kom txo tau cov ntaub sib txhuam.
Ncaj Stripe Dyeing: Txheeb xyuas seb qhov sib txawv ntawm lub nozzle tsis sib xws thiab yog tias cov ntaub ceev ruaj khov.
