Abstract:
The disclosed technology relates to a system and approach to achieve temporary adhesion of a hot-melt bonding film to a substrate, including for example a textile, leather, synthetic leather, or nonwoven substrate, so that the hot-melt film stays in place before and during the hot-melt bonding of the substrate to one or more other parts, and can even be re-positioned if needed, and then still stay in place before and during the hot-melt bonding process. In particular, an adhesive system is disclosed comprising a hot-melt adhesive and (ii) a pressure sensitive adhesive, where the hot-melt adhesive is in the form of a continuous film and where the pressure sensitive adhesive is distributed on at least one surface of said continuous film in a discontinuous pattern. In preferred embodiments said hot-melt adhesive comprises a thermoplastic polyurethane and said pressure-sensitive adhesive comprises an acrylic polymer dispersion.
