Vim li cas cov xov paj nkig tom qab dyeing nrog Sulfur Black dye? Kuv yuav tiv thaiv nws li cas? Peb yuav tsum xyuam xim rau dab tsi hauv tus txheej txheem?

Yog vim li cas spinning xov nkig tom qabSulfur Dub Brdyeing xim? Kuv yuav tiv thaiv nws li cas? Peb yuav tsum xyuam xim rau dab tsi hauv tus txheej txheem?

Ib qho sulfide dub dye yog lub siab molecular compound uas muaj cov sulfur ntau, nws cov qauv muaj cov ntawv cog lus disulfide thiab polysulfide bonds, thiab nws tsis ruaj khov heev. Tshwj xeeb, polysulfide daim ntawv cog lus tuaj yeem oxidized rau sulfur oxide los ntawm cov pa oxygen hauv huab cua hauv qee qhov kub thiab av noo, thiab ntxiv cuam tshuam nrog cov dej molecules hauv huab cua los tsim sulfuric acid, yog li txo lub zog ntawm cov xov paj spinning, fiber ntau brittleness, thiab tag nrho cov fibers yog embroidered rau hauv hmoov thaum loj. Vim li no, txhawm rau txo lossis tiv thaiv kev puas tsuaj fiber ntau tom qab spinning yarn nrogSulfur Dub Brdyeing, cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau:

① Tus nqi ntawm Sulfur Black Br dye yuav tsum raug txwv, thiab tus nqi ntawm cov xim tshwj xeeb xim yuav tsum tsis pub tshaj 700g / pob. Vim tias qhov ntau ntawm cov dyeing yog siab, lub caij nyoog ntawm brittleness yog loj, thiab ceev ceev ntawm dyeing yog txo, thiab ntxuav yog nyuaj dua.

② Tom qab cov xim yuav tsum tau ntxuav tag nrho, tsis txhob ntxuav kom huv, cov xim ntab ntawm cov xov paj spinning yog ib qho yooj yim rau decompose rau hauv sulfuric acid hauv cov txheej txheem cia thiab ua rau cov fiber ntau nkig.

③ Tom qab xim, urea, dej qab zib tshauv thiab sodium acetate yuav tsum tau siv los tiv thaiv brittleness.

④ Cov xov paj spinning yog boiled nyob rau hauv dej huv ua ntej xim, thiab embrittlement degree ntawm spinning yarn tom qab kuaj yog zoo dua li cov lye boiled xov paj.

⑤ Cov xov paj spinning yuav tsum tau qhuav nyob rau lub sij hawm tom qab xim, vim hais tias cov xov paj ntub yog tsuas yog rhuab thaum lub sij hawm stacking txheej txheem, uas yuav txo tau cov ntsiab lus ntawm anti-brittleness tus neeg saib xyuas thiab pH nqi ntawm cov xov paj spinning, uas yog unfavorable rau anti-brittleness. Tom qab ziab, cov xov paj spinning yuav tsum tau txias lawm, kom qhov kub ntawm cov xov paj spinning tuaj yeem ntim tau ua ntej yuav poob rau hauv chav tsev kub.

Vim tias nws tsis txias tom qab ziab thiab ntim tam sim ntawd, cov cua sov tsis yooj yim rau kev faib tawm, uas ua rau kom muaj zog rau cov decomposition ntawm cov xim thiab cov kua qaub, ua rau muaj peev xwm ntawm cov fiber ntau kom nkig. Kev xaiv ntawm kev tiv thaiv brittle-Sulphur Black Brdyes, xws li dyes tau ntxiv rau formaldehyde thiab chloroacetic acid thaum tsim khoom, qhov tshwm sim ntawm methyl - chlorine vulcanized los tiv thaiv brittle-dub, kom cov oxidized sulfur atoms yooj yim los ua ib lub xeev ruaj khov, uas tuaj yeem tiv thaiv oxidation ntawm sulfur atoms los tsim. acid thiab brittle fiber.
