<p>Pile carpet of nylon, polyester, or other pile yarn, is coated with 0.1 to 5 weight percent, based on weight of the pile yarn of a heat-activated adhesive powder having a melting point within the range of 100 DEG to 170 DEG C., preferably 110 DEG to 150 DEG C. For nylon pile yarn a preferred adhesive powder is a ternary copolyamide selected from the group consisting of 6/6,6/12; 6/6,6/11; and 6/6,6/12,12. The powder is heat-activated, for example to 195 DEG C. for about 60 seconds. The treated carpet displays enhanced carpet tuft appearance, improved resilience, carpet surface cleanness, and improved wear performance.</p> |
