ABSTRACT:
The thermobonding interlining is a nonwoven covered on one face with dots of thermobonding resin. According to the invention, the nonwoven is a web, containing no binding agent, of which the g/m2 weight is less than 50, which is produced from fibers in a thermoplastic material, such as polyamide; the mean diameter of the fibers is comprised between 1 and 5 .mu.m, the consolidation of the nonwoven is obtained by intermingling of the fibers by high pressure streams of fluid, notably by injection of water at pressures of 40 to 80 bars, or by thermal bonding. For example, the fibers being obtained from a mixture of constitutents having different melting points, the bonding points result from the melting and bonding of the zones of fibers having the lowest melting point.
