Method of thermally processing non-thermoplastic yarn

Claim 1

A METHOD OF IMPARTING TO NON-THERMOPLASTIC YARNS THE CAPABILITY OF BEING THERMALLY SHRUNK, STRETCHED, STABILIZED AND OTHERWISE PROCESSED AND YARN-SET, WHICH COMPRISES, CONTINUALLY DRAWING THE YARN FROM A SOURCE OF SUPPLY, CONTINUALLY APPLYING TO THE TRAVELING YARN MATERIAL SELECTED FROM THE GROUP CONSISTING OF THERMOPLASTIC AND THERMAL SETTING RESINS, CONTINUALLY TWISTING THE YARN, CONTINUALLY PASSING THE YARN AT A SELECTED LINEAR SPEED UNDER INIFORM TENSION THROUGH A RESTRICTED THERMALLY ISOLATED AND UNIFORMLY HEATED ZONE TO EVAPORATE THE EXCESS LIQUID AND UNIFORMLY HEAT THE APPLIED MATERIAL AND YARN TO A PRESCRIBED TEMPERATURE TO HEAT THE APPLIED MATERIAL AND YARN-SET- THE YARN, CONTROLLING THE SUPPLY OF HEAT ENERGY TO SAID YARN TO THEREBY MAINTAIN SAID HEATED ZONE UNIFORMLY AT THE TEMPERATURE REQUIRED TO UNIFORMLY HEAT SAID APPLIED MATERIAL AND YARN TO SAID PRESCRIBED TEMPERATURE, CONTINUALLY COOLING THE YARN TO STABILIZE THE SAME AFTER PASSAGE THEREOF UNDER TENSION THROUGH SAID HEATED ZONE, CONTINUALLY UNTWISTING THE YARN AFTER COOLING THE SAME, CONTINUALLY COLLECTING THE PROCESSED YARN, AND CONTROLLING THE TENSION UPON THE HEATED YARN RELATIVE TO THE THERMAL CHARACTERISTICS OF THE TREATED YARN AT SAID PRESCRIBED TEMPERATURE TO MAINTAIN THE SAME UNDER UNIFORM TENSION ADEQUATE TO PRECLUDE SUBSTANTIALLY ANY DUCTILITY IN THE COOLED YARN.

Claim 2

A METHOD OF IMPARTING TO NON-THERMOPLASTIC YARNS THE CAPABILITY OF BEING THERMALLY SHRUNK, STRETCHED, STABILIZED AND OTHERWISE PROCESSED AND YARN-SET, WHICH COMPRISES, CONTINUALLY DRAWING THE YARN FROM A SOURCE OF SUPPLY, CONTINUALLY APPLYING TO THE TRAVELING YARN MATERIAL SELECTED FROM THE GROUP CONSISTING OF THERMOPLASTIC AND THERMAL SETTING RESINS, CONTINUALLY TWISTING THE YARN, CONTINUALLY PASSING THE YARN AT A SELECTED LINEAR SPEED UNDER INIFORM TENSION THROUGH A RESTRICTED THERMALLY ISOLATED AND UNIFORMLY HEATED ZONE TO EVAPORATE THE EXCESS LIQUID AND UNIFORMLY HEAT THE APPLIED MATERIAL AND YARN TO A PRESCRIBED TEMPERATURE TO HEAT THE APPLIED MATERIAL AND YARN-SET- THE YARN, CONTROLLING THE SUPPLY OF HEAT ENERGY TO SAID YARN TO THEREBY MAINTAIN SAID HEATED ZONE UNIFORMLY AT THE TEMPERATURE REQUIRED TO UNIFORMLY HEAT SAID APPLIED MATERIAL AND YARN TO SAID PRESCRIBED TEMPERATURE, CONTINUALLY COOLING THE YARN TO STABILIZE THE SAME AFTER PASSAGE THEREOF UNDER TENSION THROUGH SAID HEATED ZONE, CONTINUALLY UNTWISTING THE YARN AFTER COOLING THE SAME, CONTINUALLY COLLECTING THE PROCESSED YARN, AND CONTROLLING THE TENSION UPON THE HEATED YARN RELATIVE TO THE THERMAL CHARACTERISTICS OF THE TREATED YARN AT SAID PRESCRIBED TEMPERATURE TO MAINTAIN THE SAME UNDER UNIFORM TENSION ADEQUATE TO PRECLUDE SUBSTANTIALLY ANY DUCTILITY IN THE COOLED YARN.
