METHOD FOR PROVIDING A CARRIER MATERIAL

摘要

A method to manufacture a carrier material including a nonwoven layer of fibers and threads extending in the longitudinal direction of the carrier material includes the steps of supplying a nonwoven layer of fibers, supplying a scrim comprising weft threads including a polymer having a melting temperature equal to or less than the lowest melting temperature of the thermoplastic fibers of the nonwoven layer of fibers, and thermally bonding the scrim to the nonwoven layer of fibers.

1. A method for providing a two dimensional carrier material for vinyl floor covering, roofing underlayment sheet or bitumen roofing membrane comprising a nonwoven layer of fibers and threads extending in the longitudinal direction of the carrier material, the threads extending in the longitudinal direction of the carrier material comprising high modulus yarns having a modulus of at least 1 GPa, comprising:
supplying a nonwoven layer of fibers, supplying a scrim comprising warp threads and weft threads adjacent and co-planar to the nonwoven layer of fibers, and thermally bonding the scrim to the nonwoven layer of fibers wherein the scrim comprises weft threads comprising a polymer having a melting temperature which is equal to or less than the lowest melting temperature of the fibers comprised in the nonwoven layer of fibers and which is less than the melting temperature of at least a part of the warp threads comprised in the scrim.
