Abstract

AN UNCOATED WOVEN FABRIC OF HEAT-SHRINKABLE SYNTHETIC THERMOPLASTIC YARN HAVING A VERY LOW AIR PERMEABILITY IS DISCLOSED. THE PROCESS FOR MAKING THE FABRIC COMPRISES WEAVING AS TIGHTLY AS PRACTICAL, ON A COMMERCIAL BASIS THE SYNTHETIC THERMOPLASTIC YARN (PREFERABLY A MULTIFILAMENT INTERLACED NYLON YARN HAVING SUBSTANTIALLY ZERO BUNDLE TWIST) INTO A FABRIC; AND HEATING THE FABRIC UNDER SUBSTANTIALLY NO TENSION (PREFERABLY ON A TENTER FRAME) TO A TEMPERATURE APPROACHING THE MELTING POINT OF THE YARN.

Ontario, Canada, assignors to Du Pont of Canada Limited, Montreal, Quebec, Canada Continuation of abandoned application Ser. No. 347,550, Apr. 4, 1973. This application Sept. 30, 1974, Ser. No.
Int. Cl. D03d 15/00 US. Cl. 139-420 No Drawing. 9 Pages Specification An uncoated woven fabric of heat-shrinkable synthetic thermoplastic yarn having a very low air permeability is disclosed. The process for making the fabric comprises weaving as tightly as practical, on a commercial basis the synthetic thermoplastic yarn (preferably a multifilament interlaced nylon yarn having substantially zero bundle twist) into a fabric; and heating the fabric under substantially no tension (preferably on a tenter frame) to a temperature approaching the melting point of the yarn.
