1. Kev npaj cov tshuaj zas xim. Thaum npaj cov tshuaj dyeing, thawj zaug siv me me ntawm cov dej txias los ua cov dyeing rau hauv ib qho muab tshuaj txhuam, thiab tom qab ntawd dilute nrog dej kub hauv chav tsev. Nco ntsoov tias qhov kub ntawm cov dej diluting yuav tsum tsis txhob siab dhau, siab tshaj 60 degrees, thiab lub quilt ntawm disperse dyeing yuav puas thiab coagulated, thiab cov xim yuav raug tshem tawm. Ntxiv nrog rau kev npaj, cov hmoov hmoov kuj tseem siv tau rau kev npaj, uas yog, cov dye yog maj mam sprinkled rau hauv dej txias nyob rau hauv high-speed stirring, thiab nws yuav tsum tsis txhob tso tseg rau ib ntev lub sij hawm tom qab lub dye da dej yog npaj. Tib cov zaub mov yuav tsum tau nplawm maj mam nrog stirrer kom tsis txhob los nag.
2. Kev xaiv cov dyes Thaum dyeing, sim xaiv ntau yam nrog zoo diffusivity thiab qib dyeing zog, thiab xaiv dyes nrog zoo dyeing zog thaum txuam xim.
3. Kev tu kom huv. Kev tu kom txo qis yog qhov tseem ceeb ntawm kev tshem tawm cov xim ntab. Tom qab txo kev tu, cov xim yog me ntsis lightened. Nyob rau tib lub sij hawm, lub rubbing ceev thiab lub teeb ceev ceev yog txhim kho.
4. Tar me ntsis yog cov khoom khov uas tsim nyob rau hauv cov tshuaj dye, cov khoom xyaw tseem ceeb yog dye dispersants thiab polyester oligomers. Polyester oligomer yog polyester polycondensation, nws yuav ooze tawm ntawm cov fiber ntau thiab ntws mus rau hauv cov tshuaj zas xim kom ua raws li qhov chaw ntawm cov fiber ntau thaum lub sij hawm kub kub thiab ntev dyeing txheej txheem.
