Abstract
A process for producing a continuous multifilament yarn of melt-spinnable, polymeric material comprising simultaneously draw texturing two partially oriented feeder yarn ends having different molecular orientation due to their respective spinning operations, including plying the two yarn ends together, friction texturing and air jet interlacing the resulting composite yarn. Also disclosed is the spun-like continuous multifilament yarn produced by the disclosed process as well as the resulting fabric made from the yarn.
Claims5
A process for producing a continuous multifilament yarn comprising:
- simultaneously draw texturing two partially oriented feeder yarns having different amounts of orientation from spinning, wherein said draw texturing step is characterized further to include the steps of:
- plying the two feeder yarns together;
- heating the plied feeder yarns;
- drawing the heated plied feeder yarns;
- cooling the plied feeder yarns;
- frictioning texturing the plied feeder yarns as a single yarn;
- reheating the friction textured yarn;
- entangling the reheated textured yarn;
- and cooling the textured yarn.
A process for producing a continuous multifilament yarn comprising:
- simultaneously draw texturing two oriented feeder yarns having different amounts of molecular orientation from spinning, wherein said draw texturing step is characterized further to include:
- plying the two feeder yarns together to form a single yarn;
- drawing the single yarn;
- and
- friction texturing the drawn single yarn;
- and wherein the process is characterized further to include:
- heating the drawn single yarn;
- jet entangling the drawn single yarn;
- and cooling the entangled drawn single yarn.
