Abstract
Sodium cellulose sulfate can be used alone, or in combination with other natural or synthetic gums, as thickening agents for fabric printing paste compositions containing acid dyes. The printing paste is applied in the usual manner, and then the printed goods are heated. The sodium cellulose sulfate content of the paste, upon heating, fixes the acid dye on the printed goods, thereby eliminating the necessity of using acid or acid salts in printing pastes.
