ABSTRACT:
In a method of and an apparatus for forming composite and other fibers, individual filaments from two or more sets of continuous primary filaments of two or more heat-softenable fiberizable materials are brought together lengthwise to form pairs of continuous primary filaments. The groupings of continuous primary filaments are fed into a high energy attenuation blast where the filaments are heated, attenuated and formed into composite or other staple fibers of the heat-softenable fiberizable materials. Preferably, the individual continuous primary filaments of the groupings of continuous primary filaments are fused, adhesively bonded or otherwise joined together, prior to being introduced into the high energy attenuation blast, to prevent the individual primary filaments of the groupings of continuous primary filaments from separating in the high energy attenuation blast.
