GLASS-FIBER NET REINFORCED FLUOROPLASTIC FILM AND MANUFACTURE OF FLUOROPLASTIC FILLED TWISTED GLASS-FIBER YARN NET

摘要

PROBLEM TO BE SOLVED: To make transparent a twisted glass-fiber yarn net to be a core material of a twisted glass-fiber yarn net reinforced fluoroplastic film. SOLUTION: This net is manufactured by a method wherein fluoroplastic filled twisted glass-fiber yarn is formed by purging air in a hollow part of fluoroplastic coated twisted glass-fiber yarn Fg 1 and then a fluoroplastic filled twisted glass-fiber yarn net Fg 22 is formed by weaving the yarn. By using the net as a core material in a fluoroplastic film, a transparent twisted glass- fiber yarn net reinforced fluoroplastic film is obtained.
