Abstract
The partial or superficial saponification of cellulose acetate threads or fabrics by alkaline agents prior to or during dyeing is regulated or controlled by the addition of sodium acetate in concentrations up to 5 per cent. Specification 169,741 is referred to. The Provisional Specification does not limit the invention to the above-mentioned concentrations.ALSO:The partial or superficial saponification of cellulose acetate threads or fabrics by alkaline agents prior to or during dyeing is regulated or controlled by the addition of sodium acetate in concentrations up to 5 per cent.
