    Abstract: A hook or loop component of a hook and loop fastener having a textile ground sheet (16) and filamentary pile, the ground sheet (16) penetrated by a resinous binder of improved properties. Hydrolytically stable cross-linked bonds are formed in a binder under ambient or laundering conditions. Bonds of urea-, ureido-, or urethane-type result from curing of the hook or loop ground sheet (16) by exposure to water molecules, polyfunctional amines, or polyfunctional alcohols. The resin is applied as a hot-melt, as a neat liquid, or as a solute in a solvent. In a method for applying the resin as a hot-melt, a continuous strip of hook or loop elements is heated to approximately the same temperature as the melted resin and the melted resin is applied, using a coating head and coating knife, to a section of tape suspended between two support points. Other cross-link systems and thermoplastic systems are disclosed.

    Abstract: A method for making sheets and/or plates that are thermoformable as of a temperature of 80-90 DEG C and heat-tackifiable as of 80-90 DEG C, and suitable for use as a heat-tackifiable reinforcing material. According to the method, 30-70 wt % of granules of one or more polymers that have a low melting point (50-90 DEG C) and are thermoformable as of 80-90 DEG C are mixed with 70-30 wt % of one or more polymers with a higher melting or softening point, in the form of granules or a powder having a particle size greater than around 500 mu m, and preferably of 500-1000 mu m, both kinds of polymers being thermoplastic and at least partially compatible, and optionally with the usual additives; the mixture is extruded under low-shear conditions at low temperatures of 100-140 DEG C to give a mixture having a pasty consistency that is insufficient to form a uniform mixture of molten polymers; and, after extrusion, and optionally once a fabric base (9, 12) has been added to the extruded product, said product is laminated or calendered at a high pressure and at a temperature of around 100 DEG C to reduce the thickness thereof, then cooled to less than 30 DEG C before the end of the lamination or calendering process.

    Abstract: With known methods for coating back-cloth with a synthetic powdery product, the back-cloth is subjected to heat treatments; either the length of cloth is used as a heat conveyor, or it is traversed by heat radiation. The present method allows to avoid this. Owing to a metering unit (2), the synthetic powdery product passes from a powder storage tank (1) to the powder dispensing and supply compartment (3) wherefrom it is distributed on a transport surface (5) by means of a scraper (4). Heat sources (7-9) operate without contact, directly to the synthetic powdery product arranged on the intermediary carrier. The back-cloth to be coated (11) is pressed by means of a pressure cylinder (10) against the intermediary carrier (5) where the mostly adhesive powder adheres immediately to the back-cloth (11).
