Additional information to scouring of fibre blends

Back to Scouring of fibre blends

1. DESCRIPTION OF TECHNIQUES, METHODS AND EQUIPMENT

Scouring fabrics with a blend of fibers requires consideration of the sensitivities of each fiber to scouring chemicals and to process conditions. Sensitivities to consider when scouring blends are:

Cotton

Resistant to strong alkali. Degraded by acid.

Rayon

Sensitive to alkali. May be dissolved by hot alkali.

Wool

Degraded by alkali.

Acetate

Hydrolyzed by alkali.

Polyester

Hydrolyses under extreme conditions of alkali and heat.
