2118328 9322484 PCTABS00027 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 ahdesive 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.
