ABSTRACT:
A fusible interlining includes a textile interlining web coated with a plurality of double-layered adhesive dots on a first side of the textile interlining web. Each of the plurality of double-layered adhesive dots includes a bottom dot facing the interlining web and an upper dot disposed above the bottom dot. Each bottom dot includes a binder paste containing 50 to 95 percent by weight of an acrylate binder dispersion having a glass transition temperature Tg<room temperature and 5 to 50 percent by weight of a substance that is one of an epoxy resin having an epoxy equivalent weight of 500 to 4000 mVal/kg and a copolymer of acrylates and monomers with at least one glycidyl side group. Each bottom dot may further include 0 to 20 percent by weight of a hardener. Each upper dot includes at least one of a copolyamide, a copolyester, a thermoplastic polyurethane and a polyolefin. A ratio of a mass of the bottom dot to a mass of the upper dot is from 1:0.5 to 1:5.
