Ho na le mefuta e mengata ea lidae, Reactive dyeing supplier o bua pele ka li-dyes tse sebetsang, lidae tse sebetsang ke dae e tloaelehileng haholo ebile e sebelisoa hangata.
Tlhaloso ea li-dyes tse sebetsang
Reactive dae: Reactive dyeing, eo hape e tsejoang e le reactive dae, ke mofuta oa dae o sebetsanang le likhoele nakong ea ho daea.Mofuta ona oa molek'hule oa dae o na le sehlopha se ka sebetsanang le fiber ka lik'hemik'hale.Nakong ea ho daea, dae e kopana le fiber, e etsa tlamahano e kopanetsoeng pakeng tsa tse peli le ho etsa ntho e feletseng, e leng se ntlafatsang ho potlaka ha ho hlatsoa le ho senya.
Lidae tse sebetsang li entsoe ka lidae tsa motsoali, lihlopha tse hokahanyang le lihlopha tse sebetsang.Selelekela sa dae se na le sebopeho sa azo, anthraquinone, phthalocyanine, joalo-joalo Lihlopha tse tloaelehileng tse sebetsang ka ho fetisisa ke chlorinated junsanzhen (X-mofuta le K-mofuta), vinyl sulfone sulfate (KN-mofuta) le sehlopha se sebetsang habeli (M-mofuta).Limolek'hule tsa dae tse sebetsang li na le lihlopha tse sebetsang ka lik'hemik'hale, tse ka sebetsanang le k'hothone, boea le likhoele tse ling ka tharollo e nang le metsi ho theha maqhama a tloaelehileng, e le hore lesela le dailoeng le phethiloeng le be le lebelo le phahameng la ho hlatsoa.
Lidae tse sebetsang li qhibiliha ka metsing 'me li ka hokahana ka kopanelo le likhoele tsa cellulose.E na le 'mala o khanyang, ts'ebetso e ntle ea boemo, e ka koahela liphoso tse ling tsa masela,' me e na le lebelo le letle la sesepa.Leha ho le joalo, lidae tse ngata tse sebetsang hantle ha li hanane le ho soeufala ha chlorine 'me li khona ho utloa li-acids le alkalis.Ela hloko boemo ba leholimo bo potlakileng ha u daea mebala e khanyang.Lidae tse sebetsang li ka daea k'hothone, viscose, silika, boea, nylon le likhoele tse ling.
Ho daea ka matla
Khethollo ea lidae tse sebetsang
Ho ea ka lihlopha tse fapaneng tse sebetsang, lidae tse sebetsang li ka aroloa ka mekhahlelo e 'meli: mofuta oa symmetric triazene le mofuta oa vinyl sulfone.
Symmetric triazene mofuta: Mofuteng ona oa dae e sebetsang, mofuta oa lik'hemik'hale oa athomo ea chlorine e sebetsang e sebetsa haholoanyane.Nakong ea ho daea, liathomo tsa chlorine li nkeloa sebaka ke likhoele tsa cellulose sebakeng sa alkaline ebe li fetoha lihlopha.Karabelo lipakeng tsa dae le fiber ea cellulose ke karabelo ea bimolecular nucleophilic substitution.
Mofuta oa Vinyl sulfone: Sehlopha se sebetsang se fumanehang mofuteng ona oa dae e sebetsang ke vinyl sulfone (D-SO2CH = CH2) kapa β-hydroxyethyl sulfone sulfone.Nakong ea ho daea, β-hydroxyethyl sulfone sulphate e tlosoa ka har'a alkaline ho theha sehlopha sa vinyl sulfone, se kopantsoeng le selulose fiber ebe se kenella karabelo ea ho eketsa nucleophilic ho theha covalent bond.
Mefuta e 'meli e ka holimo ea lidae tse sebetsang ka matla ke lidae tse ka sehloohong tse sebetsang tse nang le tlhahiso e kholo ka ho fetisisa lefatšeng.E le ho ntlafatsa lebelo la ho lokisa lidae tse reactive, lilemong tsa morao tjena ho 'nile ha kenngoa lihlopha tse peli tsa dae ka limolek'hule tsa dae, tse bitsoang lidae tse peli tse reactive.
Lidae tse sebetsang li ka aroloa ka lihlopha tse 'maloa ho latela lihlopha tsa tsona tse fapaneng tse sebetsang:
1. Lidae tse sebetsang tsa mofuta oa X li na le lihlopha tse sebetsang tsa dichloro-s-triazine, e leng lidae tse sebetsang ka mocheso o tlase, tse loketseng ho daea likhoele tsa cellulose ka 40-50 ℃.
2. Li-dyes tse sebetsang tsa mofuta oa K li na le sehlopha se sebetsang sa monochlorotriazine, e leng li-dyes tse nang le mocheso o phahameng oa mocheso, tse loketseng ho hatisa le ho daea pad ea masela a k'hothone.
3. Mofuta oa KN o sebetsang ka dae o na le hydroxyethyl sulfone sulfate reactive group, e leng ea mofuta oa dae o sebetsang oa mofuta oa mocheso o mahareng.Mocheso oa ho daea 40-60 ℃, o loketse ho daea moqolo oa k'hothone, ho daea ka mokhoa o batang oa ho daea, le 'mala o thibelang dae oa khatiso;hape e loketse ho daea masela a hemp.
4. Lidae tse sebetsang tsa mofuta oa M li na le lihlopha tse peli tse sebetsang 'me ke tsa lidae tse sebetsang ka mocheso o mahareng.Mocheso oa ho daea ke 60 ℃.E loketse k'hothone le line e bohareng ba mocheso oa ho daea le ho hatisa.
5. Mofuta oa KE lidae tse sebetsang li na le lihlopha tse peli tse sebetsang hantle 'me ke tsa mefuta e mengata ea mocheso oa mocheso, tse loketseng ho daea k'hothone le masela a line.Ho potlaka ha mmala
