High strength plastic coated fiber yarn fabric for structural reinforcement

Abstract

Abstract A FLEXIBLE, EXTREMELY THIN FABRIC PARTICULARLY WELL-SUITED FOR THE REINFORCEMENT OF THIN LAYERS OF PLASTER, MORTAR, CEMENT, OR LIKE STRUCTURAL MATERIALS. THE FABRIC IS COMPRISED OF FABRIC YARNS HAVING BARBED ANTI-SLIP SURFACES FIRMLY INTERFUSED IN CROSSWISE OPEN-MESH RELATIONSHIP. ADDITIONALLY, THE FABRIC YARNS RESPECTIVELY DEFINE A GENERALLY RECTANGULAR CROSS-SECTIONAL CONFIGURATION IN WHICH THE WIDTH ACROSS WHICH THE YARN IS INTERFUSED IS FROM APPROXIMATELY SIX TO EIGHTEEN TIMES GREATER THAN THE YARN THICKNESS. THE METHOD OF PRODUCING THE FABRIC INVOLVES HEATING AN OPEN-MESH FABRIC CONSTRUCTED FROM GLASS FIBER YARNS COATED WITH A THERMOPLASTIC ORGANIC COATING TO A TEMPERATURE SUFFICIENT TO TRANSFORM THE THERMOPLASTIC COATING TO A HEAT-SOFTENED FUSIBLE CONDITION. WHILE THE THERMOPLASTIC COATING REMAINS INA FUSIBLE CONDITION, THE FABRIC IS COMPRESSED TO FLATTEN AND INTERFUSE THE FABRIC YARNS. ALSO, WHILE THE THERMOPLASTIC COATING IS IN A HEATSOFTENED CONDITION FINELY-DIVIDED SOLID FRAGMENTS OF AN INORGANIC MATERIAL ARE RANDOMLY DEPOSITED OR SCATTERED ON THE SURFACES OF THE FABRIC AND EMBEDDED IN THE PLASTIC COATING TO FORM A BARBED ANTI-SLIP SURFACE ON THE FABRIC.
