Nkewa nke Reactive Dyeing

Nkewa nke Reactive Dyeing

Dịka otu dị iche iche na-emeghachi omume si dị, enwere ike kewaa ihe eji esiji na-emeghachi omume ụzọ abụọ: ụdị triazene symmetrical na ụdị vinylsulfone.

Ụdị triazene Symmetric: N'ụdị a na-esiji agba agba, ihe kemịkal nke atọm chlorine na-arụ ọrụ na-arụ ọrụ karịa.N'oge usoro agba agba, atom chlorine na-eji eriri cellulose dị na etiti alkaline dochie anya ma ghọọ otu na-ahapụ.Mmeghachi omume n'etiti agba na eriri cellulose bụ mmeghachi omume nnọchi nucleophilic bimolecular.

Ụdị vinyl sulfone: vinyl sulfone (D-SO2CH = CH2) ma ọ bụ β-hydroxyethyl sulfone sulfate.N'oge a na-esiji ákwà, β-hydroxyethyl sulfone sulfate na-ebuli na ala alkaline iji mepụta otu vinyl sulfone.Otu vinyl sulfone na-ejikọta ya na eriri cellulose iji nweta mmeghachi omume mgbakwunye nucleophilic iji mepụta njikọ nke covalent.

Agba agba abụọ a na-arụ ọrụ nke a kpọtụrụ aha n'elu bụ ụdị isi ihe eji esiji eme ihe nke nwere nnukwu mmepụta n'ụwa.Iji mee ka ọ̀tụ̀tụ̀ mmezi nke agba agba agba agba agba agba agba agba agba agba agba agba agba agba agba agba agba abụọ n'ime afọ ndị na-adịbeghị anya.

Enwere ike kewaa ihe agba agba na-emeghachi omume n'ọtụtụ usoro dịka otu ha dị iche iche si dị:

1. Ụdị X-ụdị reactive dye nwere dichloro-s-triazine reactive group, nke bụ obere okpomọkụ reactive agba, kwesịrị ekwesị maka agba cellulose eriri na 40-50 ℃.

2. K-ụdị reactive agba nwere monochlorotriazine reactive otu, nke bụ a elu okpomọkụ reactive agba, adabara ibipụta na pad dyeing nke owu akwa.

3. KN ụdị reactive agba agba nwere reactive ìgwè nke hydroxyethyl sulfone sulfate, nke bụ n'etiti okpomọkụ reactive agba agba.The dyeing okpomọkụ bụ 40-60 ℃, adabara owu mpịakọta dyeing, oyi nnukwu dyeing, na reverse dye obibi dị ka ndabere agba;dịkwa mma maka ịcha akwa akwa hemp.

4. M-ụdị reactive agba nwere okpukpu abụọ reactive otu na bụ nke etiti okpomọkụ reactive agba.Okpomọkụ agba agba bụ 60 Celsius.Ọ dị mma maka ibipụta okpomọkụ nke ọkara na ịcha akwa na akwa akwa.

5. KE ụdị reactive agba nwere okpukpu abụọ reactive otu na so na elu okpomọkụ reactive agba, nke kwesịrị ekwesị maka agba owu na linen akwa.

Njirimara

1. The agba nwere ike ime na eriri na-etolite a covalent njikọ.N'okpuru ọnọdụ nkịtị, nchikota a agaghị ekewapụ, ya mere, ozugbo agbaji agba agba na eriri, ọ ga-enwe ezigbo agba agba, karịsịa ọgwụgwọ mmiri.Tụkwasị na nke ahụ, eriri ahụ agaghị agbaji dị ka e ji esiji ákwà na-esiji ya mgbe agbachara ya.

2. Ọ nwere arụmọrụ ọkwa dị mma, agba na-egbuke egbuke, nchapụta dị mma, dị mfe iji, chromatogram zuru ezu, na ọnụ ala.

3. Enwere ike ịmepụta ya na China, nke nwere ike izute mkpa nke ụlọ ọrụ na-ebi akwụkwọ na ịcha akwa;ọ nwere ọtụtụ ihe eji eme ya, ọ bụghị naanị maka ịjiji eriri cellulose, kamakwa maka agba nke eriri protein na ụfọdụ akwa agwakọtara.

Anyị bụ ndị na-eweta ihe eji agbaji.Ọ bụrụ na ị nwere mmasị na ngwaahịa anyị, biko nweere onwe gị ịkpọtụrụ anyị.
