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.
