Ruzivo Rwakakosha rweDyes: Reactive Dyes

Muchidimbu sumo ye reactive dhayi
Kare makore anodarika zana apfuura, vanhu vaitarisira kugadzira dhayi dzinogona kuumba covalent bonds neshinda, zvoita kuti machira akadhayiwa asvikike.Kusvika 1954, Raitee naStephen veBnemen Company vakawana kuti madhayi ane dichloro-s-triazine boka anogona kubatana nemapoka ekutanga ehydroxyl pa cellulose pasi pemamiriro ealkaline Pamwe chete, uye obva adhayiwa zvakasimba pafiber, pane kirasi yedhayi dzinoshanda dzinogona. gadzira covalent zvisungo nefiber kuburikidza nemakemikari reaction, anozivikanwawo sereactive dhayi.Kubuda kwedhayi reactive kwakavhura peji nyowani yekuvandudza nhoroondo yedhayi.

Kubva pakatanga dhayi reactive muna 1956, kukura kwayo kwave kuri pamberi.Parizvino, kuburitswa kwepagore kwedhayi dzinoshanda dze cellulose fibers munyika inodarika 20% yegore rinobuda dhayi dzese.Reactive dyeing inogona kukura nekukurumidza nekuda kweanotevera maitiro:

1. Dhayi inogona kuita nefiber kuti iite covalent bond.Mumamiriro ezvinhu akajairwa, chisungo chakadaro hachizoparadzanise, saka kana dhayi rekare rikadhayiwa pafiber, rine kunaka kwekudhaya kukurumidza, kunyanya kunyorova.Pamusoro pezvo, mushure mekudhaya faibha, haizotambudzike nekupenya kwakafanana nemamwe madhayi evat.

2. Iine maitiro akanaka ekuenzanisa, ruvara rwakajeka, kupenya kwakanaka, kushandiswa kwakakodzera, chromatography yakakwana, uye mutengo wakaderera.

3. Inogona kutogadzirwa-yakawanda-yakagadzirwa muChina uye inogona kuzadzisa zvizere zvinodiwa zveindasitiri yekudhinda nedhayi;huwandu hwayo hunoshandiswa hunogona kushandiswa kwete chete kudhayiwa kwefiber cellulose, asiwo kudhayiwa kweprotein fibers uye mamwe machira akasanganiswa.

Nhoroondo ye reactive dyes
Kubva kuma1920s, Ciba yakatanga tsvakiridzo yedhayi dzecyanuric, dzine mashandiro arinani pane ese madhayi akananga, kunyanya Chloratine Fast Blue 8G.Iko kusanganiswa kwemamorekuru emukati anoumbwa nedhayi rebhuruu rine boka reamine uye dhayi yero ine mhete yecyanuric kuita toni yakasvibira, kureva kuti, dhayi ine atomu yeklorini isina kuisirwa, uye pasi pemamwe mamiriro, inogona. kuita kwakagadzira chisungo che covalent, asi hazvina kuzivikanwa panguva iyoyo.

Muna 1923, Ciba akawana kuti acid monochlorotriazine dhayi dzakadhayiwa dzemvere, dzinogona kuita kuti mvura inyatsonyorova, saka muna 1953 yakagadzira dhayi yerudzi rweCibalan Brill.Panguva imwecheteyo, muna 1952, Hearst yakagadzirawo Remalan, dhayi inoshanda yemvere dzemakwai, pahwaro hwekudzidza vinyl sulfone mapoka.Asi marudzi maviri aya edhayi haana kubudirira zvakanyanya panguva iyoyo.Muna 1956 Bu Neimen akazogadzira dhayi yekutanga yekutengesa donje, inonzi Procion, inova dhayi ye dichloro-triazine.

Muna 1957, Benemen akagadzira imwe monochlorotriazine reactive dhayi, inonzi Procion H.

Muna 1958, Hearst Corporation yakabudirira kushandisa vinyl sulfone-based reactive dhayi pakudhaya selulosi fiber, inozivikanwa seRemazol dhayi.

Muna 1959, Sandoz naCargill vakagadzira zviri pamutemo imwe dhayi yeboka, inonzi trichloropyrimidine.Muna 1971, pachikonzero ichi, kushanda kuri nani kwe difluorochloropyrimidine reactive dyes yakagadzirwa.Muna 1966, Ciba yakagadzira dhayi reactive rakavakirwa pa-bromoacrylamide, iyo ine basa rakanaka mukugadzira mvere dzemakwai, iyo yakaisa hwaro hwekushandiswa kwedhayi dzepamusoro-soro pamvere dzemakwai mune ramangwana.

Muna 1972 muBaidu, Benemen akagadzira dhayi ine maviri maviri reactive mapoka, anoti Procion HE, pahwaro hwemonochlorotriazine mhando reactive dhayi.Mhando iyi yedhayi yakawedzera kuvandudzwa maererano nekuita kwayo zvakare nekotoni fibers, fixation rate uye zvimwe zvinhu.

Muna 1976, Buneimen yakagadzira kirasi yedhayi nemapoka ephosphonic acid seboka rinoshanda.Inogona kuumba covalent bond ne cellulose fibers pasi pemamiriro asiri e-alkali, kunyanya akakodzera kudhayira nedhayi dzakapararira mubhati imwechete Iyo yakafanana paste kudhinda, zita rekutengeserana ndiPushian T. Muna 1980, zvichibva pavinyl sulfone Sumifix dye, Sumitomo. Corporation yeJapan yakagadzira vinyl sulfone uye monochlorotriazine maviri reactive boka dhayi.

Muna 1984, Nippon Kayaku Corporation yakagadzira dhayi inoshandiswa inonzi Kayasalon, iyo yakawedzera nicotinic acid inotsiva mhete ye triazine.Inogona kuita zvakabatana neselulosi fiber pasi pekushisa kwepamusoro uye mamiriro asina kwaakarerekera, saka inonyanya kukodzera kudhayiwa polyester / donje akasanganiswa machira ane tembiricha yakanyanya uye yakanyanya kudzvinyirira imwe yekugezera dhayi nzira yekuparadzira / reactive dhayi.

Reactive Dyeing

Kuumbwa kwedhayi reactive
Reactive dyeing supplier anotenda kuti musiyano mukuru pakati pedhayi dzinoshanda uye mamwe marudzi edhayi ndewekuti mamorekuru awo ane mapoka anochinja anogona kubatana nemamwe mapoka efiber (hydroxyl, amino) kuburikidza nemakemikari reaction Anonzi reactive boka).Chimiro chedhayi dzinoshanda chinogona kuratidzwa neinotevera general formula: S-D-B-Re

Muchidimbu: S-mvura-soluble boka, senge sulfonic acid boka;

D——Dye matrix;

B——Boka rinobatanidza pakati pedhayi yemubereki neboka rinoshanda;

Re-active group.

Kazhinji, kushandiswa kwedhayi reactive pane textile fibers kunofanirwa kunge kune anotevera mamiriro:

Kunyungudika kwemvura yakakwira, kugadzikana kwekuchengetedza kwakanyanya, kwete nyore kuita hydrolyze;

Iine yakakwirira reactivity kune fiber uye yakakwirira yekugadzirisa chiyero;

Chisungo chemakemikari pakati pedhayi uye fiber ine kugadzikana kwemakemikari, ndiko kuti, chisungo hachisi nyore kupera panguva yekushandiswa;

Yakanaka diffusible, yakanaka mwero kudhaya uye yakanaka dhayi kupinda;

Kutsanya kwakasiyana-siyana kwekudhaya, sechiedza chezuva, mamiriro ekunze, kugeza, kukwesha, chlorine bleaching resistance, nezvimwe zvakanaka;

Madhayi asina kubatwa uye dhayi ane hydrolyzed zviri nyore kugezwa mushure mekudhaya, pasina kusvibisa;

Kudhaya kwakanaka, kunogona kudhayiwa zvakadzika uye kwakasviba;

Mamiriro ari pamusoro apa anonyatsobatana nemapoka anogadzirisa, dhayi precursors, mapoka emvura-anonyungudika, etc. Pakati pavo, mapoka anogadzirisa ndiwo musimboti wedhayi reactive, iro rinoratidza mapoka makuru uye maitiro emagetsi ekugadzirisa.
