Additive for improving the adhesion to textiles of hot melt adhesives based on copolyamides

A polyamide adhesive composition consisting essentially of:

• A. about 96 to 99.9 by weight of a solid copolyamide of an aliphatic dicarboxylic acid, cyclic dicarboxylic acid each having 4-12 carbon atoms or mixtures thereof or said dicarboxylic acids and an equivalent amount of aliphatic diamine, cyclic diamine each having 4 - 15 carbon atoms or mixtures thereof or aminocarboxylic acid having 4-16 carbon atoms or mixtures thereof;
• and
• B. an additive of
• a. about 0.05 - 2 percent by weight based on the total weight of copolyamide of at least one acid amide of the general formula ##STR6## wherein R represents a saturated or unsaturated aliphatic hydrocarbon group having 12 - 20 carbon atoms, R.sub.1 represents an alkyl group of 1 - 3 carbon atoms, and n represents an integer of between 3 and 6;
• and
• (b) about 0.05 - 2 percent by weight of a mixture of differently condensed aminoalkyl phenols of the general formula ##STR7## wherein n' has the value of 0.5 - 2, m has the value of 2 - 6, and
• R' represents an aliphatic hydrocarbon group having 8-10 carbon atoms which is in the ortho- or para-position with respect to the OH-group.
