Classification Of Reactive Dyeing

Classification Of Reactive Dyeing

Zvinoenderana neakasiyana reactive mapoka, reactive dhayi anogona kupatsanurwa mumhando mbiri: symmetrical triazene mhando uye vinylsulfone mhando.

Symmetric triazene type: Murudzi urwu rwemadhayi anochinja, makemikari emakemikari anoshanda maatomu eklorini anowedzera kushanda.Munguva yekudhaya, maatomu eklorini anotsiviwa neselulosi fiber mune alkaline svikiro uye vobva vasiya mapoka.Kuita pakati pedhayi nefiber cellulose ndeye bimolecular nucleophilic substitution reaction.

Vinyl sulfone mhando: vinyl sulfone (D-SO2CH = CH2) kana β-hydroxyethyl sulfone sulfate.Munguva yekudhaya, β-hydroxyethyl sulfone sulfate inonaya mune alkaline medium kuti iite boka revinyl sulfone.Iro vinyl sulfone boka rinosanganiswa neiyo cellulose fiber kuita nucleophilic yekuwedzera reaction kuti iite covalent bond.

Idzo dhayi mbiri dzinoshanda dzataurwa pamusoro apa ndidzo mhando huru dzedhayi dzinoshanda dzine dhayi huru kwazvo pasi rose.Kuti uvandudze chiyero chekugadzirisa dhayi dzinoshanda, mapoka maviri anogadzirisa akaunzwa mumorekuru wedhayi mumakore achangopfuura, ari maviri maviri reactive dhayi.

Reactive madhayi anogona kukamurwa kuita akati wandei akateedzana zvichienderana neavo akasiyana reactive mapoka:

1. I-X-type reactive dhayi ine dichloro-s-triazine reactive boka, iyo yakaderera-yekushisa inogadzirisa dhayi, yakakodzera dyeing cellulose fiber pa40-50 ℃.

2. K-type reactive dhayi ine monochlorotriazine reactive boka, iyo yakakwira tembiricha reactive dhayi, yakakodzera kudhinda uye pad dyeing yemucheka wekotoni.

3. KN type reactive dyes ine reactive mapoka ehydroxyethyl sulfone sulfate, ari epakati tembiricha reactive dhayi.Iyo tembiricha yekudhaya ndeye 40-60 ℃, yakakodzera kudhaya mupumburu wedonje, dhayi inotonhora yakawanda, uye reverse dhayi kudhinda semuvara wemuvara;zvakare yakakodzera kudhayiwa kwehemp machira.

4. The M-type reactive dhayi ine kaviri reactive mapoka uye ndeyepakati tembiricha reactive dhayi.Tembiricha yekudhaya i60°C.Inokodzera kudhinda kwekushisa kwepakati uye kudhayiwa kwekotoni nerineni.

5. KE type reactive dyes ine double reactive groups uye ndeyepamusoro tembiricha reactive dhayi, akakodzera dhayi machira edonje nerineni.

Hunhu

1. Dhayi inogona kuita nefiber kuti iite covalent bond.Mumamiriro ezvinhu akajairwa, kusanganiswa uku hakuzoparadzanise, saka kana dhayi rekare rikadhayiwa pane fiber, rinenge riine ruvara rwakanaka rwekukurumidza, kunyanya kunyorova kurapwa.Pamusoro pezvo, iyo fiber haizoite brittle semamwe madhayi edhayi mushure mekudhaya.

2. Iine maitiro akanaka ekuenzanisa, mavara akajeka, kupenya kwakanaka, nyore kushandisa, chromatogram yakakwana, uye mutengo wakaderera.

3. Inogona kunge yatove yakawanda-yakagadzirwa muChina, iyo inogona kuzadzisa zvizere zvinodiwa zvekudhinda nekudhaya indasitiri;ine zvakawanda zvekushandisa, kwete chete kudhayiwa kweselulosi fibers, asiwo nokuda kwekudhayiwa kweprotein fibers nemimwe micheka yakasanganiswa.

Isu tiri Reactive Dyes Suppliers.Kana iwe uchifarira zvigadzirwa zvedu, ndapota inzwa wakasununguka kutibata nesu.
