Koj puas paub txog Sulfur Black?

sulfur dub, tseem hu ua ethyl sulfur pyrimidine, yog cov xim pleev xim organic uas siv rau hauv kev zas xim, xim thiab kev lag luam number case. Hauv kev lag luam textile, sulfur dub yog cov xim tseem ceeb rau kev zas xim cellulose fibers, uas yog qhov tshwj xeeb tshaj yog rau cov khoom tsaus ntawm cov ntaub paj rwb, ntawm cov uas

Kua Sulphur DubthiabXiav Sulphur 7yog cov feem ntau. Cov txheej txheem dyeing ntawm sulfur dye yog: ua ntej, cov sulfur dye raug txo thiab yaj rau hauv cov tshuaj dye, thiab cov dyeing leaches tsim yog adsorbed los ntawm cellulose fibers, thiab tom qab ntawd kho los ntawm huab cua oxidation kom ua rau cov cellulose fibers qhia cov xim xav tau.

Kev zas xim dub sulfur xav tau sodium sulfide ua tus neeg sawv cev txo kom yaj cov xim zas. Cov xim zas sulfide lawv tus kheej tsis yaj hauv dej, thiab thaum siv cov neeg sawv cev txo alkaline, cov xim zas tuaj yeem txo kom leucochromes thiab yaj hauv dej, thiab cov ntsev sodium leucochromic uas tsim tau tuaj yeem nqus tau los ntawm cov fibers. Hauv cov txheej txheem ua haujlwm tiag tiag, cov txheej txheem txo thiab yaj ntawm cov xim zas sulfide yuav tsum tau ua tiav, thiab tus nqi ntxiv yuav tsum qeeb thiab sib xws. Tom qab ntxiv cov xim zas, rhaub thiab zas rau 10 feeb, thiab tom qab ntawd maj mam thiab sib npaug ntxiv ntsev kom txhawb kev zas. Nco ntsoov ntxuav kom huv si tom qab zas kom tiv thaiv cov xim zas seem los ntawm kev cuam tshuam rau cov nyhuv zas. Tsis tas li ntawd, tom qab zas, tsis txhob cia li txias kom tiv thaiv "noog paw luam tawm". Tib lub sijhawm, kev kho mob tiv thaiv kev tawg yuav tsum tau siv cov tshuaj softeners thaum lub sijhawm zas.

Tsis tas li ntawd xwb, cov xim dub sulfur kuj siv tau los tsim cov xim, vim nws tiv taus lub teeb thiab huab cua zoo, yog li nws siv dav hauv kev lag luam xim. Hauv kev tsim cov kua mem, daim ntawv thov ntawm cov xim dub sulfur kuj dav heev, xws li kua mem thiab luam ntawv kua mem, nws cov xim tob, tuaj yeem muab cov nyhuv luam ntawv zoo, thiab muaj kev tiv thaiv dej, tiv taus hnav thiab tshuaj lom neeg.
