a method for manufacturing a rigid , perforated cloth wherein the cloth is woven , in both the warp and weft directions of core yarns wrapped with a thermoplastic covering yarn . after weaving , the cloth is subjected to heating at a temperature greater than the melting point of the thermoplastic covering yarn . the cloth is thereafter cooled , thereby imparting rigidity to the perforated cloth . the product of the present invention is a rigid , perforated cloth in which the individual yarns of the cloth comprise a core yarn that is covered with a thermoplastic cover . the rigid , perforated cloth displays reinforced structural networks due to the plasticity of the thermoplastic material and enhanced resistance to physical and chemical degradation .
