Vim li cas qhov dispersion dyeing ceev ceev tsis zoo?

  Disperse dyeing feem ntau yog dyeing polyester fibers nyob rau hauv qhov kub thiab txias. Txawm hais tias cov molecules ntawm dispersed dyes me me, nws tsis tuaj yeem lav tias tag nrho cov xim molecules yuav nkag mus rau sab hauv ntawm cov fibers thaum dyeing. Qee cov dyes dispersed yuav adhering rau saum npoo ntawm fibers, ua rau tsis zoo fastness. Kev tshem tawm tu yog siv los ua kom puas cov xim molecules uas tsis tau nkag mus rau hauv cov fibers sab hauv, txhim kho xim ceev, thiab lwm yam haujlwm.

   Txhawm rau kom tshem tawm cov xim ntab thiab cov seem oligomers nyob rau saum npoo ntawm polyester fabrics, tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab tsaus xim dyeing, thiab txhim kho dyeing ceev, txo kev tu feem ntau yuav tsum tau tom qab dyeing. Blended fabrics feem ntau yog xa mus rau cov xov paj ua los ntawm kev sib xyaw ntawm ob lossis ntau qhov sib xyaw, yog li muaj qhov zoo ntawm ob yam khoom. Ntxiv mus, ntau tus yam ntxwv ntawm ib feem tuaj yeem tau los ntawm kev kho nws qhov kev faib ua feem.

   Kev sib xyaw ua ke feem ntau yog hais txog kev sib xyaw ntawm cov fibers luv luv, qhov twg ob hom fibers nrog cov sib txawv sib xyaw ua ke hauv daim ntawv luv fibers. Piv txwv li, polyester paj rwb blended ntaub, tseem hu ua T / C, CVC.T / R, thiab lwm yam. Nws yog woven los ntawm ib tug blend ntawm polyester staple fibers thiab paj rwb los yog hluavtaws fibers. Nws muaj qhov zoo ntawm qhov zoo nkauj thiab hnov ​​​​ntawm tag nrho cov paj rwb ntaub, ua rau cov tshuaj fiber ntau tsis muaj zog thiab cov tshuaj fiber ntau zoo li polyester ntaub, thiab txhim kho qib.

   Txhim kho xim ceev ceev. Vim qhov kub kub dyeing ntawm polyester ntaub, xim ceev yog siab dua li ntawm tag nrho cov paj rwb. Yog li ntawd, cov xim ceev ntawm polyester paj rwb blended ntaub kuj zoo dua piv rau cov paj rwb tag nrho. Txawm li cas los xij, txhawm rau txhim kho cov xim ceev ntawm polyester paj rwb ntaub, nws yog ib qho tsim nyog yuav tsum tau txo qis kev tu (tseem hu ua R / C), ua raws li kev kho mob tom qab kub kub dyeing thiab dispersion. Tsuas yog tom qab ua qhov txo qis kev tu yuav ua tiav cov xim xav tau ceev.

   Kev sib xyaw ua ke luv fiber ntau ua rau cov yam ntxwv ntawm txhua qhov sib xyaw kom siv tau. Ib yam li ntawd, kev sib xyaw ntawm lwm cov khoom siv kuj tuaj yeem siv lawv cov txiaj ntsig kom tau raws li qee qhov kev ua haujlwm, kev nplij siab, lossis kev lag luam. Txawm li cas los xij, nyob rau hauv high-temperature dispersion dyeing ntawm polyester paj rwb blended fabrics, vim yog blending ntawm paj rwb los yog rayon fibers, dyeing kub tsis tuaj yeem siab dua li ntawm polyester fabrics. Txawm li cas los xij, thaum polyester paj rwb los yog polyester paj rwb ntaub fiber ntau yog txhawb los ntawm cov alkali muaj zog los yog kev tuav pov hwm hmoov, nws yuav ua rau muaj zog fiber ntau los yog tearing quab yuam, thiab nws yog ib qho nyuaj rau ua tiav cov khoom zoo nyob rau hauv cov theem tom ntej.
