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 chloride or sulphate or other alkali salts of strong mineral acids in concentrations up to 5 per cent. These salts may be partly replaced by sodium acetate described in Specification 176,034 or by the salts specified in Specification 175,486. Specification 169,741 also is referred to. According to the Provisional Specification the invention is not confined to the above-mentioned salts or 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 chloride or sulphate or other alkali salts of strong mineral acids in concentrations up to 5 per cent.
