ABSTRACT:
The thermo-bonding interlining is a nonwoven covered on one face with dots of thermo-bonding resin. According to the invention, the nonwoven is a web, containing no binder or thermo-fusible fibers, whose weight per square meter is between 50 and 150 g, and which is produced from filaments in a thermoplastic material, such as polyester; the mean diameter of the filaments is between 3 and 5 .mu.m, and preferably 90% of the filaments have a diameter comprised between that range; intermingling of the filaments is obtained by streams of high pressure fluid, such as streams of water at pressures of 40 to 80 bars.
