Thaum cov ntaub dyed nrog disperse dye yog txias nyob rau hauv lub dyeing vat thiab sampled thiab matched nrog tus qauv xim qauv, yog hais tias cov dyed ntaub yog ntxuav thiab kho, cov xim tone txawv me ntsis ntawm tus qauv qauv, kev kho xim yuav siv tau. Ua homework kom raug. Thaum cov xim sib txawv loj, tev thiab rov ua xim yuav tsum tau xav txog

Kev kho xim
Rau cov ntaub nrog me ntsis chromatic aberration, yuav siv tau cov hauv qab no txoj kev: Thaum tus nqi qaug zog yog txo thiab ib tug loj npaum li cas ntawm dyeing nyob rau hauv cov kua residual, nws muaj peev xwm kho tau los ntawm ncua sij hawm dyeing los yog nce lub dyeing kub. Thaum qhov dyeing qhov tob me ntsis siab dua, qhov sib txawv xim no kuj tuaj yeem kho los ntawm kev ntxiv surfactants thiab leveling.

1.1 Txoj kev kho xim
Ua ntej kho qhov ntxoov ntxoo, koj yuav tsum muaj kev nkag siab tag nrho ntawm cov xim ntawm cov ntaub dyed thiab qhov xwm txheej ntawm cov tshuaj dye. Cov hauv qab no tuaj yeem siv los hloov cov xim:
(1) Tsis tas yuav tshem tawm cov khoom dyed los ntawm dyeing vat, cia li txias cov tshuaj zas rau 50 ~ 70 ℃, thiab ntxiv cov zas xim rau kho xim uas tau npaj kom zoo;
Tom qab ntawd sov rau dyeing.
(2) Cov ntaub dyed yog unloaded los ntawm lub tshuab dyeing, thiab ces muab pov rau hauv lwm lub tshuab dyeing, thiab ces cov txheej txheem dyeing yog ua los ntawm boiling dyeing txoj kev thiab cov txheej txheem dyeing.

1.2 Cov yam ntxwv ntawm kev kho xim dyes
Nws raug pom zoo tias cov dyes siv rau kev kho xim muaj cov khoom nram qab no: (1) Cov dyes yuav tsis cuam tshuam los ntawm surfactants thiab ua qeeb dyeing. Thaum cov kev kho xim raug ua tiav, ntau qhov ntau ntawm anionic surfactant muaj nyob rau hauv cov dye tseem nyob rau hauv cov dye cawv, thiab ib tug me me ntawm cov xim kho dye yuav tsim ib tug qeeb-dyeing nyhuv vim muaj cov surfactant. Yog li ntawd, dyes rau kho xim yuav tsum tau xaiv uas tsis yooj yim cuam tshuam los ntawm surfactants thiab muaj qeeb-dyeing los.
(2) ruaj khov dyes uas tsis yooj yim cuam tshuam los ntawm hydrolysis thiab reductive decomposition. Dyes rau kev kho xim, thaum siv hauv kev kho cov xim zoo nkauj heev, cov xim yog yooj yim hydrolyzed lossis decomposed los ntawm kev txo qis. Yog li ntawd, dyes uas tsis cuam tshuam los ntawm cov yam ntxwv no yuav tsum tau xaiv.
(3) Dyes nrog zoo leveling zog. Yuav tsum muaj lub peev xwm dyeing zoo kom tau txais qib dyeing nyhuv.
(4) Dyes nrog lub teeb nrawm nrawm. Tus nqi ntawm cov dyes siv rau kev kho xim feem ntau yog tsawg heev. Yog li ntawd, nws sublimation ceev ceev thiab ntub ceev ceev yog ib qho tseem ceeb heev, tab sis tsis ceev li lub teeb ceev ceev. Feem ntau, cov dyes siv rau kev kho xim yog xaiv los ntawm cov dyes siv nyob rau hauv thawj dyeing formula. Txawm li cas los xij, cov dyes qee zaum tsis ua raws li cov xwm txheej saum toj no. Hauv qhov no, nws raug nquahu kom xaiv cov hauv qab no haum rau kev kho xim
xim:
CI (Dye Index): Disperse Yellow 46; Khawb Liab 06; Disperse Liab 146; Disperse Violet 25; Disperse Violet 23; Xiav Xiav 56.

Peeling thiab re-staining

Thaum lub xim ntawm cov ntaub dyed txawv los ntawm tus qauv qauv, thiab nws tsis tuaj yeem kho los ntawm cov xim trimming lossis qib dyeing, nws yuav tsum tau stripped thiab rov dyed. Poly-txias fiber ntau muaj cov qauv crystalline siab. Yog li nws tsis tuaj yeem siv txoj hauv kev dav dav kom tshem tawm cov xim tag nrho. Txawm li cas los xij, qee qhov kev tev tawm tuaj yeem ua tiav, thiab nws tsis tas yuav tev tag nrho thaum rov dyeing thiab kho cov xim.

2.1 Ib feem ntawm stripping agent
Txoj kev stripping no siv lub zog retarding ntawm surfactants los strip xim. Txawm hais tias cov nyhuv stripping yog me me, nws yuav tsis decompose cov xim los yog ua rau lub siab ntawm cov ntaub dyed. Cov txheej txheem stripping ib txwm yog: pab: nonionic surfactant kaum anionic surfactant 2 ~ 4L, kub: 130 ℃, Q: 30 ~ 60min. Saib Table 1 rau dye stripping kev ua tau zoo.

2.2 Restore peeling
Txoj kev tev no yog ua kom sov cov ntaub dyed nyob rau hauv lub tshav kub conduction npoo kom tev tawm cov xim, thiab ces siv ib tug txo tus neeg sawv cev los rhuav tshem cov decomposed dye, thiab cais cov decomposed dye molecules ntawm fiber ntau li ntau tau. Nws cov nyhuv tev yog zoo dua li ib feem ntawm txoj kev tev. Txawm li cas los xij, tseem muaj ntau yam teeb meem nrog txoj kev tev no. Xws li cov reattachment ntawm cov puas thiab decomposed dye molecules; cov xim tom qab tev tawm yuav txawv ntawm cov xim qub. Kev xav ntawm tes thiab hnyav dyeability ntawm dyed ntaub yuav hloov; cov dye qhov ntawm fiber ntau yuav txo qis, thiab lwm yam.
Yog li ntawd, txoj kev txo stripping tsuas yog siv thaum yav dhau los ib nrab stripping tsis tuaj yeem kho tau zoo. Daim ntawv qhia txog kev txo cov xim yog raws li hauv qab no:
Dye guide agent (feem ntau yog hom emulsion) 4g/L
Tsis yog (anionic) ionic nto active tus neeg sawv cev 2g / L
Caustic soda (35%) 4ml / L
Insurance hmoov (los yog Dekuling) 4g / L
Kub 97 ~ 100 ℃
Lub sijhawm 30 min

2.3 Oxidation peeling method
Txoj kev stripping no siv oxidation los decompose cov dye rau stripping nws, thiab nws muaj ib tug zoo stripping nyhuv tshaj qhov txo stripping txoj kev. Cov tshuaj oxidation stripping txheej txheem yog raws li nram no:
Dye guide agent (feem ntau yog hom emulsion) 4g/L
Formic acid (formic acid) 2 ml / L
Sodium chlorite (NaCLO2) 23g / L
Chlorine Stabilizer 2g / L
Kub 97 ~ 100 ℃
Lub sijhawm 30 min

2.4 hnyav staining
Feem ntau siv dyeing txoj kev tuaj yeem siv los rov dye cov ntaub stripped, tab sis qhov dyeability ntawm cov ntaub dyed tseem yuav tsum tau sim thawj zaug, uas yog, cov qauv chav ua haujlwm dyeing yuav tsum tau ua. Vim tias nws qhov kev ua haujlwm dyeing yuav loj dua li ua ntej tev.

Cov ntsiab lus

Thaum cov xim zoo dua yuav tsum tau ua, cov ntaub tuaj yeem oxidized thiab tev tawm ua ntej, thiab tom qab ntawd txo cov tev. Vim tias qhov txo qis thiab oxidation tev tawm yuav ua rau cov ntaub dyed rau crimp, uas yuav ua rau cov ntaub zoo li ntxhib thiab tawv, nws yuav tsum tau txiav txim siab ua tiav hauv cov txheej txheem tsim khoom tiag tiag, tshwj xeeb tshaj yog cov tev ntawm cov xim sib txawv uas tau piav qhia hauv Table 1. Xim kev ua haujlwm. Nyob rau hauv qhov tseeb hais tias cov xim sib xws tuaj yeem ncav cuag tus qauv xim qauv, feem ntau siv txoj kev kho kom zoo dua qub. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua cov qauv fiber ntau tsis puas, thiab lub zog tearing ntawm cov ntaub yuav tsis poob zoo heev.
