YARNS AND FIBERS OF GOOD PROPERTIES BASED ON MIXING VINYL POLYHLORIDE AND SURCHLORINE VINYL POLYHLORIDE AND PROCESS FOR OBTAINING THEM

摘要

THE PRESENT INVENTION CONCERNS YARNS AND FIBERS BASED ON A MIXTURE OF ATLANTIC VINYL POLYHLORIDE AND VINYL SUPERCHLORINATED POLYCHLORIDE AND THEIR PROCESS OF OBTAINING THE YARNS AND FIBERS ACCORDING TO THE PRESENT INVENTION HAVE A RESIDUAL REMOVAL RATE IN BOILING WATER LOWER THAN 2, AN ELASTICITY MODULE EXCEEDING 3KNMM, AND A WITHDRAWAL STRESS, AFTER RETRACTION IN AQUEOUS FLUID MEDIUM AT A TEMPERATURE BETWEEN 98 AND 130C, GREATER THAN OR EQUAL TO 1, 6 10GDTEX. / P P THESE YARNS ARE OBTAINED BY WIRING AND STRETCHING KNOWN IN SELF, THEN STABILIZING UNDER CONTINUOUS VOLTAGE AT A TEMPERATURE OF BETWEEN 105 AND 125C IN THE PRESENCE OF WATER VAPOR UNDER PRESSURE DURING 1 TO 3 SECONDS THEN RETRACTION IN AQUEOUS FLUID MEDIUM AT TEMPERATURE BETWEEN 98 AND 130C. / P P THE YARNS AND FIBERS ACCORDING TO THE INVENTION ARE USED FOR MAKING FABRICS, KNITTED FABRICS, NON-WOVEN ARTICLES ALONE OR IN MIXTURE WITH OTHER FIBERS. / P
