Lub Ntsiab Cai ntawm Kev Tshem Tawm

Kev rhuav tshem yog kev siv tshuaj lom neeg los rhuav tshem cov xim ntawm cov fiber thiab ua rau nws poob nws cov xim.
Muaj ob hom tshuaj lom neeg tseem ceeb uas siv los tshem xim. Ib qho yog cov tshuaj uas ua rau cov xim ploj mus los yog tshem xim los ntawm kev rhuav tshem cov xim hauv cov qauv molecular ntawm cov xim. Piv txwv li, cov xim uas muaj cov qauv azo muaj ib pawg azo. Nws yuav raug txo kom ua ib pawg amino thiab poob nws cov xim. Txawm li cas los xij, qhov puas tsuaj ntawm cov tshuaj uas ua rau cov xim ntawm qee cov xim tuaj yeem rov qab tau, yog li qhov ploj mus tuaj yeem rov qab tau, xws li cov qauv xim ntawm cov qauv anthraquinone. Sodium sulfonate thiab hmoov dawb feem ntau yog cov tshuaj uas ua rau cov xim ploj mus. Qhov thib ob yog cov tshuaj oxidative stripping, uas feem ntau siv yog hydrogen peroxide thiab sodium hypochlorite. Nyob rau hauv qee qhov xwm txheej, cov tshuaj oxidants tuaj yeem ua rau muaj kev puas tsuaj rau qee pawg uas ua rau cov xim molecular ntawm cov xim, xws li kev rhuav tshem cov pawg azo, kev oxidation ntawm cov pawg amino, methylation ntawm cov pawg hydroxy, thiab kev sib cais ntawm cov hlau ions nyuaj. Cov kev hloov pauv tsis rov qab tau no ua rau cov xim ploj mus los yog tshem xim, yog li ntawd, cov tshuaj oxidative stripping tuaj yeem siv rau kev kho kom tiav. Txoj kev no zoo tshwj xeeb rau cov xim uas muaj cov qauv anthraquinone.

Kev tshem tawm cov xim feem ntau

5.4.3.2 Txoj kev ua haujlwm thiab cov kauj ruam
Ua raws li txoj kev zas xim thiab cov kauj ruam ib txwm muaj.

Kev qhia luv luv txog cov txheej txheem stripping xim ntawm cov ntaub sib xyaw

Cov xim disperse thiab acid tuaj yeem raug tev tawm ib nrab ntawm cov ntaub diacetate/wool sib xyaw nrog 3 txog 5% alkylamine polyoxyethylene ntawm 80 txog 85 ° C thiab pH 5 txog 6 rau 30 txog 60 feeb. Kev kho mob no kuj tseem tuaj yeem tshem tawm ib nrab ntawm cov xim disperse los ntawm cov khoom acetate ntawm diacetate/nylon thiab diacetate/polyacrylonitrile fiber sib xyaw. Kev tshem tawm ib nrab ntawm cov xim disperse los ntawm polyester/polyacrylonitrile lossis polyester/wool yuav tsum tau ua kom npau nrog lub hnab nqa khoom rau txog 2 teev. Ntxiv 5 txog 10 grams/liter ntawm cov tshuaj ntxuav tsis-ionic thiab 1 txog 2 grams/liter ntawm cov hmoov dawb feem ntau tuaj yeem txhim kho qhov tev tawm ntawm cov polyester/polyacrylonitrile fibers.

1 g/L tshuaj ntxuav anionic; 3 g/L tshuaj cationic dye retardant; thiab 4 g/L sodium sulfate kho ntawm qhov kub npau thiab pH 10 rau 45 feeb. Nws tuaj yeem tshem tawm cov alkaline thiab acid dyes ntawm nylon/alkaline dyeable polyester sib xyaw ntaub.

1% tshuaj ntxuav khaub ncaws uas tsis yog ionic; 2% tshuaj cationic dye retardant; thiab 10% txog 15% sodium sulfate kho ntawm qhov kub npau thiab pH 5 rau 90 txog 120 feeb. Feem ntau siv rau kev rhuav cov ntaub plaub/polyacrylonitrile fiber.

Siv 2 txog 5 grams/liter ntawm caustic soda, thiab 2 txog 5 grams/liter ntawm sodium hydroxide, txo qhov kub ntawm 80 txog 85°C, lossis cov tshuaj alkaline nruab nrab ntawm cov hmoov dawb ntawm 120°C, uas tuaj yeem tau los ntawm polyester/cellulose. Muaj ntau cov xim ncaj qha thiab cov xim reactive raug tshem tawm ntawm qhov sib xyaw.

Siv 3% txog 5% hmoov dawb thiab cov tshuaj ntxuav anionic los kho rau 4O-6O feeb ntawm 80 ℃ thiab pH4. Cov xim disperse thiab acid tuaj yeem raug stripped ntawm diacetate / polypropylene fiber, diacetate / wool, diacetate / nylon, nylon / polyurethane, thiab acid dyeable nylon textured yarn.

Siv 1-2 g/L sodium chlorite, rhaub rau 1 teev ntawm pH 3.5, kom tshem tawm cov xim disperse, cationic, direct lossis reactive ntawm cov ntaub cellulose/polyacrylonitrile fiber sib xyaw. Thaum tshem tawm cov ntaub triacetate/polyacrylonitrile, polyester/polyacrylonitrile, thiab polyester/cellulose sib xyaw, yuav tsum ntxiv cov tshuaj ntxuav uas tsim nyog thiab cov tshuaj ntxuav uas tsis yog ionic.

Kev txiav txim siab txog kev tsim khoom

7.1 Cov ntaub yuav tsum tau kuaj ua ntej tev lossis kho qhov ntxoov ntxoo.
7.2 Yuav tsum ntxuav (dej txias los yog dej kub) tom qab daim ntaub raug tev tawm lawm.
7.3 Kev tshem tawm yuav tsum yog lub sijhawm luv luv thiab yuav tsum rov ua dua yog tias tsim nyog.
7.4 Thaum tshem tawm cov xim, cov xwm txheej ntawm qhov kub thiab cov khoom ntxiv yuav tsum tau tswj hwm nruj raws li cov yam ntxwv ntawm cov xim nws tus kheej, xws li kev tiv thaiv oxidation, kev tiv thaiv alkali, thiab kev tiv thaiv chlorine bleaching. Txhawm rau tiv thaiv cov khoom ntxiv ntau dhau lossis kev tswj qhov kub tsis raug, ua rau tev tawv ntau dhau lossis tev tawv. Thaum tsim nyog, cov txheej txheem yuav tsum tau txiav txim siab los ntawm kev tawm tsam.
7.5 Thaum cov ntaub raug tev tawm ib nrab, cov xwm txheej hauv qab no yuav tshwm sim:
7.5.1 Rau kev kho qhov tob ntawm cov xim zas, qhov ntxoov ntxoo ntawm cov xim zas yuav tsis hloov ntau, tsuas yog qhov tob ntawm cov xim yuav hloov pauv. Yog tias cov xwm txheej ntawm kev tshem tawm cov xim raug tswj hwm, nws tuaj yeem ua tau raws li qhov xav tau ntawm cov qauv xim;
7.5.2 Thaum cov ntaub uas muaj ob lossis ntau cov xim pleev uas muaj tib qho kev ua tau zoo raug tshem tawm ib nrab, qhov kev hloov pauv xim me me. Vim tias cov xim pleev tsuas yog raug tshem tawm mus rau tib qib, cov ntaub uas raug tshem tawm tsuas yog tshwm sim Kev Hloov Pauv tob xwb.
7.5.3 Rau kev kho cov ntaub zas xim nrog cov xim sib txawv hauv qhov tob xim, feem ntau nws yog qhov tsim nyog los tshem tawm cov xim thiab rov zas xim dua.
