Dyebleach-BL is a one bath polyester dyeing and cotton bleaching agent for polyester cotton (P/C) blended fabrics. Dyebleach-BL is useful to shorten the process cycle of polyester and polyester blended fabrics. Dyebleach-BL can be used in processing of polyester blended fabric whereby one can start the dyeing of polyester without bleaching by adding recommended dosage of Dyebleach-BL. Dyebleach-BL will take care of making cotton absorbent and white. While cooling the disperse dye bath to 80 deg.C, addition of caustic and peroxide (30 min.) will bleach the cellulosic portion thereby improving the fastness of disperse dye without reduction clearing process. Drop the bath, give one cold wash with acetic acid and start cotton dyeing as normal process. During washing of cotton dyeing, add Combiwash-PC (no need of other washing agent) which helps giving better wash fastness.
Dyebleach-BL does not affect the colour yield of disperse dyes. The whiteness and hydrophilicity of cotton is similar to the results with the conventional two bath process.
