ABSTRACT:
Melt blended fibers of lactam-polyol-polyacyl lactam or acyl polylactam terpolymers together with polyesters are thermally bonded at temperatures below the bonding temperatures of either the crystalline polyester or the terpolymer, resulting in thermally stable fabrics that have bond strength greater than the individual polyester or terpolymer webs bonded at the same temperature.
