Classification ntawm Reactive Dyeing

Classification ntawm Reactive Dyeing

Raws li cov sib txawv reactive pawg, reactive dyes yuav muab faib ua ob hom: symmetrical triazene hom thiab vinylsulfone hom.

Symmetric triazene hom: Nyob rau hauv hom reactive dyes, cov khoom siv tshuaj ntawm cov tshuaj chlorine atoms muaj zog dua.Thaum lub sij hawm dyeing txheej txheem, chlorine atoms yog hloov los ntawm cellulose fibers nyob rau hauv alkaline nruab nrab thiab ua tawm hauv pawg.Cov tshuaj tiv thaiv ntawm cov dye thiab cellulose fiber yog bimolecular nucleophilic hloov cov tshuaj tiv thaiv.

Vinyl sulfone hom: vinyl sulfone (D-SO2CH = CH2) los yog β-hydroxyethyl sulfone sulfate.Thaum lub sij hawm dyeing txheej txheem, β-hydroxyethyl sulfone sulfate precipitates nyob rau hauv ib tug alkaline nruab nrab los tsim ib pawg vinyl sulfone.Cov vinyl sulfone pab pawg ua ke nrog cov cellulose fiber kom dhau los ua cov tshuaj tiv thaiv nucleophilic ntxiv los tsim cov ntawv cog lus covalent.

Ob lub reactive dyes tau hais los saum toj no yog cov ntau yam ntawm reactive dyes nrog cov khoom loj tshaj plaws nyob rau hauv lub ntiaj teb no.Txhawm rau txhim kho tus nqi fixation ntawm reactive dyes, ob pawg reactive tau qhia rau hauv cov xim molecule nyob rau hauv xyoo tas los no, uas yog dual reactive dyes.

Reactive dyes tuaj yeem muab faib ua ntau yam raws li lawv cov pab pawg sib txawv:

1. X-hom reactive dye muaj dichloro-s-triazine reactive pawg, uas yog ib tug low-temperature reactive dye, haum rau dyeing cellulose fiber ntawm 40-50 ℃.

2. K-hom reactive dye muaj monochlorotriazine reactive pawg, uas yog kub kub reactive dye, haum rau luam ntawv thiab ncoo dyeing ntawm paj rwb ntaub.

3. KN hom reactive dyes muaj reactive pawg ntawm hydroxyethyl sulfone sulfate, uas yog nruab nrab kub reactive dyes.dyeing kub yog 40-60 ℃, haum rau paj rwb yob dyeing, txias tej dyeing, thiab thim rov qab dye printing raws li cov xim tom qab;kuj haum rau dyeing ntawm hemp textiles.

4. M-hom reactive dye muaj ob pawg reactive thiab belongs rau nruab nrab kub reactive dye.Qhov kub ntawm dyeing yog 60 ° C.Nws yog tsim rau nruab nrab kub luam ntawv thiab dyeing ntawm paj rwb thiab linen.

5. KE hom reactive dyes muaj ob pawg reactive thiab koom nrog kub kub reactive dyes, uas yog tsim rau dyeing paj rwb thiab linen fabrics.

Yam ntxwv

1. Cov zas xim tuaj yeem hnov ​​​​mob nrog cov fiber ntau los ua ib daim ntawv cog lus.Nyob rau hauv ib txwm muaj xwm txheej, qhov kev sib xyaw ua ke no yuav tsis cuam tshuam, yog li thaum cov tshuaj zas xim reactive yog dyed ntawm fiber ntau, nws yuav muaj xim zoo, tshwj xeeb tshaj yog kev kho ntub dej.Tsis tas li ntawd, cov fiber ntau yuav tsis nkig zoo li qee cov vat dyes tom qab dyeing.

2. Nws muaj kev ua haujlwm zoo, cov xim ci, ci ci zoo, siv tau yooj yim, ua tiav chromatogram, thiab tus nqi qis.

3. Nws tuaj yeem ua tau loj hauv Suav teb, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam luam ntawv thiab dyeing;Nws muaj ntau yam kev siv, tsis yog tsuas yog rau dyeing ntawm cellulose fibers, tab sis kuj rau dyeing ntawm protein fibers thiab ib co blended fabrics.
