All of the fibers within the resin matrix are oriented in substantially a single direction and the matrix material has an elongation-to-failure that exceeds that of the fibers.

The thermoplastic material has a weld elongation-at-break of at least 3%.

The yarns are drawn such that the actual draw ratio is within 10 percent of the predicted draw ratio determined according to: [(elongation to break of the feed yarn)+115]/[(elongation to break of the drawn yarn)+115)].

By means of these crimps it is possible to obtain steel structures with an increased penetration of rubber or with an increased elongation at break.

A biaxially oriented film of only polyarylene sulfide resin excelling in rupture elongation and planarity.

The metallic filaments of the cabled strands have an elongation at break that is no more than 24 percent different from the elongation at break of the synthetic filaments of the first and second bundles.

The synthetic filaments of the cabled strands have an elongation at break that is no more than 25 percent different from the elongation at break of the metal filaments of the first and second bundles.

The hollow-fiber porous membrane obtained is excellent in mechanical strength represented by tensile strength and elongation at break and in chemical resistance.

More specifically, the preferred base nonwoven has a cross-machine direction elongation at break of at least about 175 % and a cross-machine direction tensile strength of at least about 400 g/in.

Staple fibres with high tenacity and elongation at break and non-woven fabrics are prepared from such an olefin polymer composition.

The extensible portion is extensible in at least one direction, and has elongation to break of at least 250 percent, a stress at 100 percent elongation of greater than 300 N/cm2.

The addition of 0.5 wt. % of b-CPO has been shown to improve impact strength by as much as 85% and elongation at break exhibited by the blend by as much as 170%.

The resulting fibres have excellent mechanical textile properties, especially a good tear strength, elongation at tear, permanent elongation and heat distortion temperature.

As a result, provided are: an artificial polypeptide fiber having high toughness and favorable stress and rupture elongation; and a method for producing the artificial polypeptide fiber.

The thermoplastic material with the weld can have a weld elongation-at-break of at least 3%.
