Nzira uye Maitiro ekunyungudutsa Dyes

1.Direct Dyes

Kugadzikana kwekupisa kwedhayi dzakananga kunenge kwakanaka.

Paunenge uchinyungudutsa dhayi dzakananga, inogona kuwedzerwa soda yakapfava mvura yekubatsira solubilization.

Chekutanga, shandisa mvura inotonhora yakapfava kumutsa madhayi kuti aname. Uye wobva wawedzera kufashaira mvura yakapfava kuti inyungudusedyes. Zvadaro, wedzera mvura inopisa kuti uwedzere. Mushure mekutonhora, wedzera mvura kune yakataurwa.

2.Reactive Dyes

Reactive dhayi haadziviri kupisa. Pakupisa kwepamusoro, zvinonyungudika nyore nyore mumvura.

Inogona kushandisa mvura inotonhora yakapfava kumutsa madhayi kuti aname. Uye wobva washandisa yakakodzera tembiricha yakapfava mvura yekunyungudutsa madhayi zvinoenderana nehydrolytic kugadzikana kwedhayi dzakasiyana. Zvadaro, wedzera mvura inopisa inopisa kuti uwedzere. Mushure mekutonhora, wedzera mvura kune yakataurwa.

Yakadzika tembiricha mhando (X Type): Shandisa mvura inotonhora kana 30 ~ 35 ℃ mvura inodziya (Yakanyanya kubviswa)

Kupisa kwemhando yepamusoro (K Type uye HE Type, nezvimwewo): Shandisa 70 ~ 80 ℃ mvura inopisa

Tembiricha yepakati (KN Type uye M Type): Shandisa 60 ~ 70 ℃ mvura inopisa

Kune madhayi ane low solubility, ndapota shandisa 90 ℃ mvura inopisa.

3.Vat Dyes

Iyo yekunyungudutswa kwevat dhayi inzira yekudzikisa maitiro.

Paunenge uchinyungudutsa vat dhayi, tembiricha yekunyungudika inofanirwa kutariswa nemamiriro ekudzikisa ekushandiswa kuderedzamumiririri. Semuenzaniso, iyo inowanzo shandiswa yekudzikisa mumiririri wevat dhayi ndeye sodium hydrosulfite. Iyo yakanyanya kunaka tembiricha yebasa i60 ℃. Kunyanya kupisa kunotungamira mukuora kwakawanda kwe sodium hydrosulfite.

4.Sulfur Dyes

Nyatsoyera huwandu hunodiwa hwedhayi mubeaker uye wedzera mvura inotonhora yakapfava. Shingairira madhayi kuti aname. Wobva wawedzera sodium sulfide dhayi doro rinenge ranyungudutswa uye worifashaira kwemaminetsi gumi. Zvadaro, wedzera mvura inopisa inopisa kuti uwedzere. Mushure mekutonhora, wedzera mvura kune yakataurwa.

5.Disperse Dyes

Kana tembiricha yekubikira yanyanya, madhayi ekuparadzira ari nyore kuburitsa.

Pakunyungudukadispersemadhayi, anogona kumutswa kuti aname pekutanga nemvura inotonhora yakapfava. Uye isu mvura inotonhora yakapfava pazasi 40 ℃ kunyungudutsa madhayi. Zvadaro wobva wawedzera mvura kuhuwandu hwakatarwa.

6.Acid Dyes

Kugadzikana kwekupisa kwedhayi dzeasidhi kwakanaka.

Chekutanga, shandisa mvura inotonhora yakapfava kumutsa madhayi kuti aname. Uye wobva wawedzera kufashaira mvura yakapfava kuti uparadze madhayi. Zvadaro, wedzera mvura inopisa kuti uwedzere. Mushure mekutonhora, wedzera mvura kune yakataurwa.

7.Cationic Dyes

Kugadzikana kwekupisa kwe cationic dhayi kwakanaka.

Chekutanga, shandisa acetum acerrimum (yekubatsira solubilization) kumutsa madhayi kuti aname. Uye wobva wawedzera kufashaira mvura yakapfava kuti uparadze madhayi. Zvadaro, wedzera mvura inopisa kuti uwedzere. Mushure mekutonhora, wedzera mvura kune yakataurwa.
