Acrylics:- Explained in brief
by : Rahul Sharma
Acrylics:-
Acrylics are scoured with a synthetic detergent at 110-1500F and rinsed before further processing to remove tints, size, wax, grease, spinning oils or other impurities applied or picked up during the weaving operation. Bleaching when required, is usually accomplished by means of a sodium chlorite bleach, a selected optical brightener or suitable combination of the two. Acrylic-blend fabrics may require other bleaching agents if chlorine-sensitive fibres are present.
Most acrylic fabrics require presetting in open width in boiling water, followed by drying at moderately low temperatures in order to avoid dimensional stability problems during subsequent wet-processing steps.
