Koj Puas Paub Txog Sulfur Black?

sulfur dub, tseem hu ua ethyl sulfur pyrimidine, yog cov organic hluavtaws dye tsuas yog siv hauv dyeing, pigment thiab number case industries. Hauv kev lag luam textile, leej faj dub yog cov xim tseem ceeb rau dyeing cellulose fibers, uas yog tshwj xeeb tshaj yog haum rau cov khoom tsaus nti ntawm paj rwb fabrics, ntawm cov uas.

Kua Sulfur DubthiabSulfur Blue 7yog cov feem ntau. Cov txheej txheem dyeing ntawm sulfur dyeing yog: ua ntej, cov sulfur dye yog txo thiab yaj mus rau hauv cov tshuaj dyeing, thiab cov dyeing leaches tsim yog adsorbed los ntawm cellulose fibers, thiab ces kho los ntawm huab cua oxidation kom cov cellulose fibers qhia cov xim yuav tsum tau.

Sulfur dub dyeing yuav tsum sodium sulfide ua tus neeg sawv cev txo kom yaj cov xim. Sulfide dyes lawv tus kheej yog insoluble nyob rau hauv dej, thiab thaum siv alkaline txo cov neeg ua hauj, dyes yuav txo tau leucochromes thiab yaj nyob rau hauv dej, thiab cov tsim leucochromic sodium ntsev yuav adsorbed los ntawm fibers. Hauv cov txheej txheem kev ua haujlwm tiag tiag, kev txo qis thiab kev sib cais ntawm sulfide dyes yuav tsum tau ua tiav, thiab tus nqi sib ntxiv yuav tsum qeeb thiab sib xws. Tom qab ntxiv cov dyeing, boil thiab dye rau 10 feeb, ces maj mam thiab sib npaug ntxiv ntsev los txhawb dyeing. Nco ntsoov ntxuav kom huv si tom qab dyeing los tiv thaiv cov dye residual los ntawm kev cuam tshuam cov nyhuv dyeing. Tsis tas li ntawd, tom qab dyeing, tsis txhob cia txias los tiv thaiv "noog paw prints". Nyob rau tib lub sijhawm, kev kho mob los tiv thaiv brittleness yuav tsum tau siv cov softeners thaum lub sij hawm dyeing txheej txheem.

Tsis tas li ntawd, sulfur dub kuj tuaj yeem siv los tsim cov pigments, vim nws lub teeb pom kev zoo thiab huab cua tsis kam, yog li nws tau siv dav hauv kev lag luam pigment. Hauv kev tsim cov number case, daim ntawv thov ntawm sulfur dub kuj yog dav heev, xws li tus number case thiab luam ntawv number case, nws cov xim sib sib zog nqus, tuaj yeem muab cov nyhuv luam ntawv zoo, thiab muaj dej tsis kam, hnav tsis kam thiab tshuaj lom neeg.
