A LAMINATE CONSISTING OF AT LEAST THREE LAYERS AND A METHOD FOR PRODUCING A LAMINATE CONSISTING OF AT LEAST THREE LAYERS

摘要

A nonwoven consisting of continuous filaments is produced directly at spinning and bonded with a hot fluid, e.g. hot air. It is covered on both sides with a thermoplastic film, which is attached by means of adhesive or melt bonding. The nonwoven can be slightly compacted by light calendering or needle-punching prior to bonding. An independent claim is also included for the process involving thermally bonding the non-woven so that its final thickness is at least 40 %, preferably at least 80 % of the initial thickness. It is then covered with a film on both sides attached with a melt adhesive.
