ABSTRACT:
Process and product obtained by the process by which an undrawn or partially drawn continuous filament yarn serving as an effect yarn component and a continuous filament yarn having a greater orientation than the effect yarn component and serving as a core yarn component are heated above glass transition temperature by co-current and counter-current heated gaseous flows to form in the filaments of the effect yarn component at random intervals along the lengths of the individual filaments coils, loops or whorls, with more drafting occurring in those portions of the filaments having the coils, loops or whorls than the other portions, and with more drafting occurring in some loops than others; intermingling the effect yarn component with the core yarn component, and at the same time heat setting the yarn components within the heated gaseous flows.
