Abstract
The partial alkaline saponification of cellulose acetate threads, films, or fabrics, to facilitate dyeing, is carried out by first treating the goods with a hot or cold salt solution, and then saponifying with substantially cold caustic alkali. If desired, a little alkali or alkaline-earth hydroxide may be added to the salt bath, to prime the subsequent saponification. Sodium, calcium, or magnesium chloride are suitable salts for the pretreatment bath. Mixed goods containing cellulose acetate and cellulose threads may be treated by the process. Specification 20672/10 is referrel to.ALSO:The partial alkaline saponification of cellulose acetate threads, films, or fabrics, to facilitate dyeing, is carried out by first treating the goods with a hot or cold salt solution, and then saponifying with substantially cold caustic alkali.
