ABSTRACT:
Additives for textile hot melt adhesives based on copolyamides comprising, based on the total weight of copolyamide:
A. 0.05 - 2 percent by weight of at least one acid amide of the general formula ##STR1## wherein R represents a saturated or unsaturated aliphatic hydrocarbon group of 12-20 carbon atoms, R.sub.1 represents an alkyl group of 1 to 3 carbon atoms, and
n represents an integer of between 3 and 6; and
B. 0.05 - 2 percent by weight of a mixture of differently condensed aminoalkyl phenols of the general formula ##STR2## wherein N' CAN ASSUME THE VALUE OF 0.5 - 2,
m can assume the value of 2 - 6, and
R' represent an aliphatic hydrocarbon group of 8-10 carbon atoms which is in the ortho- or para-position with respect to the OH-group.
