Dyeing Of Sulphur Dyes

硫化染料染色方法Dyeing of Sulphur Dyes

一.低温染色 Microtherm Dyeing

染色工艺 Dyeing procedure

染料 纯碱

Dye Sodium Carbonate

硫化碱 元明粉

Sodium Sulphide Carbonate Sulphate

----------------------------------------------------

60°C

二.说明 Explain

①最佳起染温度60℃,如某些染料需要较高染色温度,则缓慢升温至沸,近45-60分钟.

Dyeing is started advantageously at 60℃,In the case of dyes which are to be dyed hot,the temperature is raised to the boil slowly and the material dyed near the boil for 45-60 minutes.

②又能从入染起始温度50-55℃,升温到80℃,续染45-60分钟.

Dyes could becarriedout at the temperature above 80 for 45-60 minutes by the initial temperature at 50-55℃.

③如某些染料需在低温染制较鲜艳而丰满的色泽,则从30-40℃,升入染温到50-60℃,续45 分钟,如需染浅色,则低温入染,缓慢升温,不加元明染色.

With dyes which yield brighter and in particular fuller dyeing at low temparature,the goods

areentered to the dyebathat 30-40℃,and dyed at 50-60℃for 45minutes.Also when pale shades are needed,the goodsare entered at low temperature and the bathshould be heated gradully.In this case,dyeing is carriedout best without addition of sodium sulphate.
