Sulfur Lub Teeb Yellow GC CI. 53120

Sulfur Lub Teeb Yellow GC (CI. 53120, CI Sulfur Yellow 2) yog cov tshuaj zawv plaub hau classical siv dav hauv kev lag luam textile, feem ntau rau dyeing cellulosic fibers xws li paj rwb, linen, viscose, thiab vinylon.

Physical thiab Chemical Properties

Cov xim no zoo nkaus li yellowish -xim av los yog reddish- xim av hmoov. Nws yog insoluble nyob rau hauv dej tab sis yuav soluble nyob rau hauv ib tug txo tus neeg saib xyuas xws li sodium sulfide (Na₂S), uas hloov cov dye rau hauv leuco (dej- soluble) daim ntawv uas muaj ib tug muaj zog affinity rau cellulose. Lub zog ua lag luam zoo li ntawm 200% txog 250%.

Txheej txheem thov

Cov txheej txheem dyeing muaj peb kauj ruam tseem ceeb:

1. Txo & Dissolution: Cov xim yog boiled nrog sodium sulfide thiab ib tug me me ntawm soda tshauv los ua ib tug ntshiab, daj -xim av.

2. Nthuav Dyeing: Cov ntaub yog immersed nyob rau hauv lub da dej no ntawm 85-95 degree, qhov uas txo dyeing absorbs rau hauv fibers.

3. Oxidation: Tom qab dyeing, cov khoom raug rau huab cua los yog oxidizing tus neeg sawv cev (xws li hydrogen peroxide los yog poov tshuaj dichromate), uas re-oxidizes cov xim rau nws cov qub insoluble lub xeev, mus tas li kaw cov xim nyob rau hauv lub fibers.

Kev siv & ceev ceev

Sulfur Lub Teeb Yellow GC muaj nuj nqis rau kev tsim cov xim daj zoo nkauj - daj rau txiv ntseej - ntxoov ntxoo daj. Nws muaj qhov zoo rau kev ua kom pom kev zoo (5-6 ntawm cov ntaub plaub xiav) thiab kev ntxuav zoo heev, txawm tias chlorine -bleach fastness tsis zoo. Nws yog feem ntau siv rau cov khaub ncaws ua haujlwm, denim, tub rog fabrics, thiab hnyav - cov ntaub ntawv textiles. Nws kuj tseem ua haujlwm hauv kev lag luam tawv thiab ua lub hauv paus rau kev tsim cov txiv ntseej, khaki, thiab xim av ntxoov ntxoo los ntawm cov xim sib xws.

Kev nyab xeeb & kev txwv

Ib qho tseem ceeb drawback yog nws lub peev xwm rau "bronzing" (ib tug metallic nto sheen) yog siv tsis raug. Ib puag ncig, cov txheej txheem sulfur dye cov txheej txheem tuaj yeem tsim cov sulfide- muaj cov dej khib nyiab, yuav tsum tau kho kom raug. Txawm li cas los xij, cov xim nws tus kheej tsis muaj cov hlau hnyav xws li cov pab pawg azo, ua rau nws tus nqi - siv tau zoo rau cov dyes ncaj qha lossis reactive dyes rau cov xim hnyav.

Hauv cov ntsiab lus, Sulfur Lub Teeb Yellow GC tseem yog ib qho kev lag luam thiab ceev ceev -kev xaiv kev ntseeg siab rau nruab nrab- mus rau -dub daj tones ntawm cov ntaub ntawv cellulosic.
