ABSTRACT:
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.
