  • Patent number: 6515048
    Abstract: An adhesive powder for bonding flat, closed, or porous substrates, the adhesive powder being applied in the first step to a first substrate, an intermediate product that is non-adhesive at room temperature and stable in storage being produced, and the first substrate being bonded to a second substrate in a second step by applying an increased temperature and pressure, as a combination of the following components: i) a thermoplastic polymer having a proportion of 25 to 95% by weight; and ii) at least one epoxy resin that is solid at room temperature and has a proportion of 5 to 75% by weight; and, if desired, iii) at least one pre-adduct of epoxy resins and polyamines that is solid at room temperature and has a proportion of at most 25% by weight, a physical bonding taking place when the adhesive powder is applied to the first substrate in the first step, and the two substrates being bonded in the second step by the powder components being chemically cross-linked or post-cross-linked among one another, and bei

  • Patent number: 5063101
    Abstract: Disclosed is a textile product and a method for making that product for a shirt or blouse interlining formed of a bonded base material having bonded thereon a fleece of adhesive fibers. A plurality of adhesive dots are applied on that surface of the fleece opposite to the surface bonded to the base material. The dots are substantially in a singular planar arrangement and, at least some of the dots, are separated from the base material by the fleece. The interlining can be fused to a shirt fabric such, as a broadcloth, to provide a good and smooth surface appearance. With the product of the invention, the smooth surface appearance is retained even after washing.
