An object of the present invention is to provide an elastic signal transmission cable having a length of several centimeters to several meters that has a shape deformation tracking ability and enables high-speed signal transmission. The inventive elastic signal transmission cable has an elasticity of 10% or more and transmission loss of 10 dB/m or less in a relaxed state at 250 MHz, and comprises an elastic cylindrical body having an elasticity of 10% or more and a conductor portion containing at least two conductor wires wound in the same direction around the elastic cylindrical body.

Elastic signal transmission cable

A spun yarn comprising poly(trimethylene terephthalate) staple fibers at a content of at least 15% by weight, the spun yarn having an elastic recovery percentage of elongation at 5% elongation (%) &gE;0.1 X&plus;70 (wherein X represents the content of poly(trimethylene terephthalate) staple fibers in the spun yarn (wt %)). The spun yarn is excellent in knitting and weaving characteristics, stretchability and stretch-back property and in shape stability and durability when worn for a prolonged period of time.

Spun yarn

The present invention provides a polytrimethylene terephthalate monofilament yarn excellent in softness, bending recovery or durability against a long term use. The inventive polytrimethylene terephthalate monofilament yarn is constituted by trimethylene terephthalate composed of 90 mol % or more of trymethylene terephthalate repeating units and 10 mol % or less of other ester repeating units, wherein the yarn has a single-fiber size of 50 dtex or more, an intrinsic viscosity in a range from 0.8 to 1.3 dl/g, and a boiling water shrinkage of 2% or less.
