Kuv Yuav Qhia Li Cas Dye Peb Siv Rau Hotel Linen?

Cov hom dyes ntawm cov ntaub yog qhov nyuaj rau kev txheeb xyuas nrog lub qhov muag liab qab thiab yuav tsum raug txiav txim siab los ntawm cov txheej txheem tshuaj. Yog tias peb tsis txheeb xyuas hom dyes ua ntej, peb yuav txiav txim siab cov khoom tsis tsim nyog raws li cov khoom tsim nyog. Muaj undoubtedly zoo tsis zoo. Cov neeg siv yuav muaj kev pheej hmoo rau kev noj qab haus huv.

• Sampling thiab pre-processing

Cov kauj ruam tseem ceeb hauv kev txheeb xyuas hom dye hauv cellulose fibers yog sampling thiab qauv pretreatment. Thaum noj cov qauv, ib feem ntawm cov xim tib yam yuav tsum tau muab coj los siv. Yog tias cov qauv muaj ob peb lub suab, txhua xim yuav tsum muab coj los siv. Yog xav tau kev txheeb xyuas fiber ntau, hom fiber ntau yuav tsum tau lees paub raws li FZ / TO1057 tus qauv. Yog tias muaj impurities, roj, thiab slurry ntawm cov qauv uas yuav cuam tshuam qhov kev sim, nws yuav tsum tau kho nrog xab npum hauv dej kub ntawm 60-70 degree rau 15 feeb, ntxuav, thiab qhuav.

• Kev txheeb xyuas cov txheej txheem ntawm cov dyes ncaj qha

Boil tus qauv nrog 5 mus rau 10 mL ntawm cov tshuaj aqueous uas muaj 1 mL ntawm concentrated ammonia dej kom tag nrho tshem tawm cov xim.

Tshem tawm cov qauv, muab 10-30 mg ntawm cov paj rwb dawb thiab 5-50 mg ntawm sodium chloride rau hauv cov tshuaj extraction, boil rau 40-80 vib nas this, cia kom txias, thiab tom qab ntawd ntxuav nrog dej. Yog tias peb zas cov ntaub paj rwb dawb rau yuav luag tib lub xim zoo li cov qauv, peb tuaj yeem txiav txim siab tias cov xim uas siv los zas cov qauv yog cov xim ncaj qha.

• Yuav ua li cas txheeb xyuas sulfur dyes

Muab ib qho piv txwv 100-300mg rau hauv 35-mL xeem raj, ntxiv 2-3 mL dej, 1-2 mL ntawm 10% sodium carbonate tov, thiab 200-400 mL ntawm sodium sulfide. Kub thiab boil rau 1-2 feeb. Tshem tawm 25-50 mg ntawm cov paj rwb dawb thiab 10-20 mg ntawm cov qauv sodium chloride hauv ib lub raj kuaj. Boil rau 1-2 feeb. Tshem tawm thiab muab tso rau ntawm daim ntawv lim kom nws rov oxidize. Yog hais tias lub teeb xim tshwm sim zoo ib yam li cov xim qub thiab tsuas yog txawv ntawm qhov ntxoov ntxoo, peb tuaj yeem xav txog nws sulfide lossis sulfide vat dye.

• Yuav ua li cas txheeb xyuas vat dyes

Muab ib qho piv txwv ntawm {{0}}mg mus rau hauv ib lub raj 35-mL, ntxiv 2-3 mL dej thiab 0.5-1 mL ntawm 1{{15} }% sodium hydroxide tov, cua sov thiab boil, ces ntxiv 10-20 mg ntawm kev tuav pov hwm hmoov, boil rau 0.5-1 feeb, tshem tawm cov qauv, thiab muab tso rau hauv ib tug 25-10% sodium hydroxide tov. 50mg dawb paj rwb ntaub thiab 0-20 mg sodium chloride; txuas ntxiv boil rau 40-80 vib nas this; ces txias rau chav tsev kub. Tshem tawm cov ntaub paj rwb thiab muab tso rau ntawm daim ntawv lim rau oxidation. Yog tias cov xim tom qab oxidation zoo ib yam li cov xim qub, nws qhia tias muaj vat dye.

• Yuav ua li cas txheeb xyuas cov dyes reactive

Cov yam ntxwv ntawm reactive dyes yog tias lawv muaj cov tshuaj tiv thaiv ruaj khov nrog fibers thiab nyuaj rau yaj hauv dej thiab cov kuab tshuaj. Tam sim no, tsis muaj txoj hauv kev yooj yim tshwj xeeb. Peb tuaj yeem ua qhov kev kuaj xim ua ntej, siv 1: 1 aqueous tov ntawm dimethyl methylamine thiab 100% dimethyl formamide los xim cov qauv. Cov dye uas tsis xim yog cov reactive dye.

• Yuav txheeb xyuas cov xim li cas

Coatings, tseem hu ua pigments, tsis muaj affinity rau fibers thiab yuav tsum tau kho nyob rau hauv lub fibers los ntawm ib tug nplaum (feem ntau yog ib tug resin nplaum). Peb tuaj yeem siv microscopy los kuaj xyuas. Ua ntej, tshem tawm cov hmoov txhuv nplej siab los yog cov khoom ua kom tiav uas muaj nyob rau ntawm cov qauv kom tiv thaiv lawv los ntawm kev cuam tshuam nrog kev txheeb xyuas cov xim. Ntxiv 1 tee ntawm ethyl salicylate rau cov fiber ntau kho saum toj no, npog nws nrog ib daim ntaub npog, thiab saib nws hauv qab lub tshuab tsom. Yog hais tias lub fiber nto zoo nkaus li granular, peb tuaj yeem txheeb xyuas nws raws li cov xim resin-bonded pigment (xim).
