PROCESS FOR MAKING COMPOSITE YARN OF CONTINUOUS FILAMENTS AND STAPLE FIBERS

摘要

An improved process for making a composite yarn of staple fibers commingled with bulked continuous filaments comprises passing a yarn of crimped continuous filaments while under tension between nip rolls which advance the yarn into a splaying zone where the filaments are permitted to contract and splay of their own accord into an open three-dimensional filament network into which airborne staple fibers are projected for commingling with the filaments after which the open network is collapsed and the composite yarn is withdrawn at a slightly lower speed than that at which the nip rolls advance the feed yarn.
