Bonding of polyester material

Abstract

Abstract PURPOSE:To bond polyester materials to each other easily without any adhesive, by subjecting the bonding surface of one of the materials to a low-temperature plasma treatment and subjecting that of the other material to a corona discharge treatment in bonding said materials by application of heat and pressure. CONSTITUTION:The bonding surface of one of polyester materials to be bonded is subjected to a low-temperature plasma treatment in argon, nitrogen or helium gas of 1X10<-3>-1Torr or a mixture thereof under conditions of a discharge power >=100W. The bonding surface of the other material is subjected to a corona discharge treatment in air, carbon dioxide gas, nitrogen gas, argon gas, oxygen gas, or a gaseous mixture thereof under conditions of a discharge power >=100W. Both the pretreated materials are bonded to each other by application of heat and pressure. In this way, they can be bonded to each other with a bonding strength sufficient for practical use.
