Abstract

A rigid fabric for industrial applications, esp. filter cloths is produced from thermoplastic synthetic yarns or fibres which contract under theinfluence of heat, by first weaving a flexible fabric of multifilament yarns, heating the fabric to near melting point under low tension so that the filaments contract and coalesce to form quasi-monofilament yarns of approx. circular cross section, and finally cooling to give a rigid fabric of similar properties to one woven from coarse monofilament yarsns. One or more of the constituents of the synthetic material may be volatile, so that it is expelled during the heating process to leave a porous yarn. The flexible fabric can be woven without difficulty on conventional looms, and without the problems associated with the processing of heavy-gauge monofilaments.
