Abstract

A process for the production of aminated cotton fibers by subjecting a raw cotton or cotton-polyester mixture to a modification with a saturated aliphatic compound of 3 to 15 carbon atoms which contains at least one primary, secondary, tertiary, or quaternary amino group and at least one hydrolyzable ester group, in which the saturated radical is straight chain, branched, or cyclic, and may be interrupted by one or more hetero groups and may be substituted by one or more hydroxyl groups. The modification occurs simultaneously with scouring, kiering, or dry mercerizing.
