Abstract
Method of spot coating garment interlinings comprising a suspension agent for synthetic resin powders comprising an aqueous emulsion wherein there is contained, in a concentration of about 1-7.5 percent by weight: (A) a mixture of about 95-40 molar percent of an aminoamide of the general formula ##STR1## wherein R represents a saturated or unsaturated hydrocarbon group having 18-19 carbon atoms, n represents an integer of between 2 and 6, and R.sub.1 and R.sub.2 represent alkyl groups having 1-3 carbon atoms; and (B) about 5-60 molar percent of a fatty acid or mineral acid salt of this aminoamide.

- n represents an integer of between 2 and 6, and
- R.sub.1 and R.sub.2 represent alkyl groups having 1-3 carbon atoms;
- and
- (b) about 5-60 molar percent of an acid salt of said aminoamide;
- and
- II. a concentration of about 25-50 percent by weight synthetic resin powders having melting points not more than about 140.degree. C.;
- and
- spot coating said garment interlinings with said aqueous dispersion.
