Abstract
An article of furniture is made from elongated polymer filaments. The polymer filaments may be monofilaments or plural filaments which are twisted together and heat set to prevent their untwisting during the subsequent weaving process. The heat setting of the polymer filaments is achieved by heating the polymer material either before or after the twisting process.

A method of making a composite twisted elongated yarn, said method comprising providing a first elongated yarn of polymer material, said first elongated yarn having a deformed outer surface and a non-uniform cross-section over its entire length, providing a second elongated yarn of polymer material, heating said first elongated yarn to a temperature below the softening temperature of said polymer material, heating said second elongated yarn to a temperature below the softening temperature of said polymer material, and twisting said first and second elongated yarns together after said heating to form a composite yarn therefrom having a twisted shape, wherein said temperature is sufficient to prevent said composite yarn from untwisting without said first and second elongated yarns adhering to each other.
A method of making a composite twisted elongated yarn, said method comprising providing a first elongated yarn of polymer material having shape memory properties, said first elongated yarn having a deformed outer surface and a non-uniform cross-section over its entire length, providing a second elongated yarn of polymer material having shape memory properties, heating said first elongated yarn to a temperature below the softening temperature of said polymer material, heating said second elongated yarn to a temperature below the softening temperature of said polymer material, and continually twisting after said heating said first and second elongated yarns together to form a composite yarn therefrom having a twisted shape, wherein said temperature is sufficient to cause said first and second elongated yarns to lose their shape memory properties sufficiently to prevent said composite yarn from untwisting without said first and second elongated yarns adhering to each other.
A method of making an article having a frame and a woven portion formed from elongated twisted yarns, said method comprising forming a composite twisted yarn by providing a first elongated yarn of polymer material, said first elongated yarn having a deformed outer surface and a non-uniform cross-section over its entire length, providing a second elongated yarn of polymer material, heating said first elongated yarn to a temperature below the softening temperature of said polymer material, heating said second elongated yarn to a temperature below the softening temperature of said polymer material, and twisting said first and second elongated yarns together after said heating to form a composite yarn therefrom having a twisted shape, wherein said temperature is sufficient to prevent said composite yarn from untwisting without said first and second elongated yarns adhering to each other;
- weaving said twisted yarn into a woven portion;
- providing a frame;
- and attaching said woven portion to said frame.
