Reactive Cold Brand Dyes

Parshwactive M Brand Dyes (Dichlorotriazine)

PARSHWACTIVE M BRAND DYES are highly reactive requiring comparatively milder conditions in dye fixation. They are primarily of interest in dyeing at normal room temperature (about 25º - 30º Deg. C) using Soda Ash or Sodium Bicarbonate. PARSHWACTIVE M BRAND dyes are applicable to cellulosic textiles by Batch-wise, Semi-continuous and Continuous methods in conventional textile machinery like open-vat, Package, Jet, Jig, Winch and padding mangle. The versatility in various application procedures and the availability of wide range of bright and fast shades are the outstanding features of this class of dyestuffs.

General Characteristics Of 'M' Brand Dyes

Stability

The dyestuff should be stored in cool and dry conditions. The containers should be tightly closed when not in use. High temperature, Humidity and alkaline pH conditions reduce the stability of the dyes in solution.

Water supply

Soft of the softened water should be employed, avoiding alkalinity especially while dissolving the dyes, when hard along is available, it should be softened with sequestering agents. In dyeing, the pH of the water supply should be within the limits pH -7-8.

Method Dyeing

Receive cold water in the dye bath (Recommended m/l ratio 1 to 15), add required quantity of common salt or gluber salt. Paste required dyes with the water and dissolve by adding water 30º C to same. Add dissolved dye to the dye bath. Enter material, run 15 to 20 minutes. Add required amount of soda ash (as solution), run material for 45 to 60 minutes, squeeze, wash with water and soap at boil with 2g/L soap, wash with water and dry. Soaping treatment is highly essential to remove unfixed dye to produce dyeings of high washing fastness.
