摘要： 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.degree. to 170.degree. C., preferably 110.degree. to 150.degree. 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.degree. C. for about 60 seconds. The treated carpet displays enhanced carpet tuft appearance, improved resilience, carpet surface cleanness, and improved wear performance.

摘要： The method of this invention comprises the improvement of using an open frame skein carrier with arms to loosely hang the yarn skeins. This allows a shorter total heat-setting time; eliminates kinks, and improves bulk and bulk uniformity of the yarn.

摘要： The invention is directed to a process for producing bulked synthetic multifilament yarn comprising a plurality of continuous synthetic filaments having deposited thereon at intermittent intervals an adhesive polymer component having a melting temperature below that of the continuous synthetic filaments. The process comprises texturizing synthetic multifilament yarn to obtain desired bulk characteristics by directing heated yarn in a current of heated fluid against a yarn plug contained in a texturizing chamber, applying said adhesive polymer component in a molten condition to the surface of said yarn plug, and continuously discharging texturized yarn from said texturizing chamber at a lower linear rate than the feed rate of said yarn to said texturizing zone while said adhesive polymer component is still in a molten but solidifying state, resulting in bulked synthetic multifilament yarn having the adhesive polymer component deposited thereon at intermittent intervals.
