Treatment for grey cotton fabric:

(a) Desizing:

The grey cotton fabric was desized with alkali and soap solution. In same bath scouring was also done. The bath composition for desized and scouring process is as follows.

NaOH 2 g/l

Na2Co3 2 g/l

Soap 1 g/l

Weight of grey fabric 80 gm

Time for heating 1 hour

Temperature of the bath - 100°C

The process can be represented by a line diagram as shown below

The fabric after desizing and scouring is swilled with water until all alkali and soap is removed.

(b) Bleaching:

The post treated fabric was bleached with suitable bleaching agent to get a white fabric. The composition of the bleaching bath is given below with experimental conditions.

Na2SiO3 2 g/l

NaOH 2 g/l
