Kune akawanda marudzi edhayi, Reactive dyeing supplier kutanga kutaura nezve reactive dhayi, reactive dhayi ndeye yakajairika uye inowanzoshandiswa dhayi.
Tsanangudzo yedhayi dzinoshanda
Reactive dyeing: Reactive Dyeing, inozivikanwawo sereactive dye, imhando yedhayi inopindirana nefiber panguva yekudhaya.Iri rudzi rwemorekuru wedhayi rine boka rinogona kuita zvemakemikari nefiber.Panguva yekudhaya, dhayi inopindirana nefiber, ichiita chisungo checovalent pakati pezviviri uye kuumba yese, iyo inovandudza kukurumidza kushambidza nekukwesha.
Reactive dhayi anoumbwa nevabereki dhayi, kubatanidza mapoka uye reactive mapoka.Iyo dhayi precursor ine azo, anthraquinone, phthalocyanine chimiro, etc. Mapoka anowanzo shanda chlorinated junsanzhen (X-mhando uye K-mhando), vinyl sulfone sulfate (KN-mhando) uye kaviri-reactive boka (M-mhando).Reactive dhayi mamorekuru ane makemikari anoshanda mapoka, ayo anogona kuita nekotoni, mvere dzemakwai uye mamwe mafiber muine aqueous solution kuti iite chisungo chakafanana, kuitira kuti jira rakapedzwa rakapedzwa rive nekumhanya kwekugeza.
Reactive madhayi anonyungudika mumvura uye anogona kuwirirana ne cellulose fibers.Iine ruvara rwakajeka, kuita kwakanaka kwekuenzanisa, inogona kuvhara mamwe machira akaremara, uye ine sipo yakanaka yekumhanya.Nekudaro, madhayi mazhinji anobatika haakwanise kurwisa chlorine bleaching uye anonzwa kune acids uye alkalis.Ngwarira kumhanyisa kwemamiriro ekunze paunenge uchidhaya mavara akareruka.Reactive dhayi anogona kupenda donje, viscose, sirika, makushe, naironi uye mamwe mafibhi.
Reactive Dyeing
Classification ye reactive dyes
Zvinoenderana nemapoka akasiyana anoshanda, dhayi dzinoshanda dzinogona kukamurwa kuita mapoka maviri: symmetric triazene mhando uye vinyl sulfone mhando.
Symmetric triazene type: Murudzi urwu rwedhayi reactive, chimiro chemakemikari cheiyo reactive chlorine atomu inonyanya kushanda.Panguva yekudhaya, maatomu echlorine anotsiviwa neselulosi fiber mune alkaline medium uye anosiya mapoka.Kuita pakati pedhayi nefiber cellulose ndeye bimolecular nucleophilic substitution reaction.
Vinyl sulfone type: The reactive group iri murudzi urwu rwedhayi reactive is vinyl sulfone (D-SO2CH = CH2) kana β-hydroxyethyl sulfone sulfone.Munguva yekudhaya, β-hydroxyethyl sulfone sulphate inobviswa mu alkaline yepakati kuita vinyl sulfone boka, iro rinobva rasanganiswa ne cellulose fiber uye rinopinda nucleophilic yekuwedzera reaction kuti iite covalent bond.
Mhando mbiri dziri pamusoro apa dzedhayi dzinoshanda ndiwo madhayi makuru ane dhayi ane yakakura kubuda pasirese.Kuti uvandudze chiyero chekugadzirisa dhayi dzinoshanda, mapoka maviri emagetsi akaiswa mumamorekuru edhayi mumakore achangopfuura, anonzi dual reactive dyes.
Reactive madhayi anogona kukamurwa kuita akati wandei akateedzana zvichienderana neavo akasiyana reactive mapoka:
1. X-type reactive dyes ine dichloro-s-triazine inoshanda mapoka, ayo ari pasi-temperature reactive dhayi, akakodzera kudhaya selulosi fiber pa40-50 ℃.
2. K-type reactive dyes ine monochlorotriazine reactive boka, iyo yakakwirira-yepamusoro reactive dyes, yakakodzera kudhinda uye pad dyeing yemucheka wekotoni.
3. KN type reactive dhayi ine hydroxyethyl sulfone sulfate reactive boka, inova yepakati tembiricha mhando reactive dhayi.Kudhaya tembiricha 40-60 ℃, yakakodzera kudhaya donje roll dhayi, inotonhora stacking dhayi, uye anti-dhayi kudhinda kumashure ruvara;zvakare yakakodzera kudhaya machira ehemp.
4. M-type reactive dhayi dzine dual reactive groups uye ndedzepakati tembiricha mhando reactive dhayi.Tembiricha yekudhaya i60 ℃.Inokodzera donje nerineni yepakati tembiricha yekudhaya uye kudhinda.
5. KE type reactive dyes ine double reactive groups uye ndeyemhando yepamusoro tembiricha reactive dhayi, yakakodzera dhayi machira edonje nerineni.Kutsanya kwemavara
