Dyeing ntawm acrylic yarn
1. Dyeing dej
Txij li cov cationic dyes yog dyed nrog cov pab pawg muaj zog acid, acrylic fibers tau yooj yim cuam tshuam los ntawm cov hlau ions xws li calcium ions hauv dej. Tsis tas li ntawd, qee cov cationic dyes kuj raug rau cov hlau ions. Yog tias cov dej zoo tsis haum rau kev dyeing, nws yuav tsum tau kho kom haum kom txo tau cov dej tsis zoo ntawm dyeing.
Tsis tas li ntawd, yog tias cov dej kais dej muaj cov tshuaj chlorine, nws yuav tsum tau deactivated ua ntej nws yuav siv tau.
2. Kev kho kom zoo
Tej yam yooj yim scouring yog ua raws li qhov xav tau los tshem tawm cov roj spinning ntawm acrylic fiber, cov ntaub so ntswg ntawm cov txheej txheem dhau los thiab ntau yam kab mob, kom cov txheej txheem tom ntej xws li dyeing thiab xov tuaj yeem ua tau zoo.
Cov nram qab no yooj yim scouring kev kho mob yuav ua tau ntawm acrylic fibers:
Noionic surfactant {{0}} 5-1.0g/L
Ua haujlwm kub 60 degree
Lub sijhawm ua haujlwm 20-40min.
Muaj ntau ntau yam khoom siv scouring siv rau scouring, uas tuaj yeem xaiv los ntawm ntau yam khoom tsim los ntawm ntau lub tuam txhab.
3. tshuaj dawb thiab dawb
Lub whiteness ntawm acrylic fibers twb heev heev. Yog tias yuav tsum tau ua kom tawv nqaij ntau dua, yuav tsum tau kho fluorescent whitening los yog ua ke nrog tshuaj bleaching.
Kev siv cov tshuaj fluorescent whitening agents rau kev kho hniav dawb yog yooj yim thiab siv dav. Muaj ob hom fluorescent whitening agents: cationic fluorescent whitening agents thiab dispersion fluorescent whitening agents. Raws li txoj kev dyeing ntawm cationic dyes los yog disperse dyes, whitening kev kho mob yog nqa tawm feem. Vim tias qhov qib zoo dua thaum siv cov dispersion hom fluorescent whitening agent, feem ntau siv cov dispersion type fluorescent whitening agent.
