Cationic dyes yog dab tsi?

Cationic dyestuaj yeem sib cais rau hauv qhov zoo them ions hauv cov tshuaj aqueous.Lawv tuaj yeem cuam tshuam nrog cov pab pawg tsis zoo ntawm cov molecules fiber ntau los tsim cov ntsev, uas tuaj yeem txuas ntxiv rau cov fibers, yog li staining cov fibers.Cationic dyes tau ua tiav tiav raws li alkaline dyes.Lub hauv paus ntsiab lus stained ntawm cationic dyes yog zas cov fibers los ntawm kev sib txuas lawv cov cations nrog acidic pawg hauv peb monomer ntawm acrylon, yog li ua rau muaj kev ceev ceev.

Daim ntawv thovNtawm Cationic dyes:

1.Dyeing ntawm hluavtaws fibers: Cationic xims yogFeem ntau siv rau dyeing ntawm polyester fiber thiab acrylic fiber.Lub cationic chromophore yog thawj absorbed los ntawm fiber nto nrog tsis zoo hluav taws xob thiab ces diffuses mus rau hauv lub sab hauv ntawm fiber nyob rau hauv ib tug siab kub;nws khi rau cov active acid pawg tab sis nws cov kev nkag mus tau nyob ntawm qhov kub thiab txias muaj pes tsawg leeg.Yog li ntawd, dyeing yam ntxwv ntawm cationic dyes yog txiav txim los ntawm affinity thiab diffusibility.

2.Dyeing ntawm daim ntawvthiabtawv: Cationic dyes muab affinity zoo rau qhov tsis zoo nqi ntoo pulp thiab unbleached pulp qib.Cationic dyes raug xaiv rau lawv txoj kev ci ntsa iab thiab kev siv zog, ua rau lawv tshwj xeeb tshaj yog siv rau qib ntawv rov ua dua tshiab.Cationic dyes yog thawj cov organic dyes siv los zas tawv tawv thiab thawj zaug siv rau dyeing zaub tanning tawv.Lawv kuj tau siv los tsim cov tshuab ntaus ntawv ribbon thiab luam ntawv.
