(57) @ A process is provided for producing highly resilient, textured, continuous multifilament
polymeric yarns and combinations of such yarns with other continuous filament yarns
and with spun yarns. The unstable or wild loops which form in conventional air jet
textured yarns are substantially eliminated in the product yarns of this invention.
The product yarns are formed by continuously drawing polymeric yarn under controlled
temperature conditions, texturing the yarn in an air jet texturizer (14) and subjecting
the textured yarn to saturated steam (18) while restraining the linear shrinkage of
the yarn in the presence of the steam, followed by continuous take-up of the yarn
on a package (22).
