    Abstract: PURPOSE:To reduce unevenness of physical properties among single yarn, and to improve strength, by copolymerizing an isophthalic acid component containing a specific amount of metallic sulfonate group with a specified amount of a glycol component having a molecular weight limited to a specific range and drawing it under a specific condition. CONSTITUTION:An isophthalic acid component containing 1.0-2.0mol, preferably 1.3-1.8mol metallic sulfonate group is copolymerized with 0.5-1.9wt%, prefer ably 0.7-1.5wt% glycol component having 400-6,000, preferably 400-1,500. The modified polyester having 82-105 polymerization degree is melted, extrud ed, solidified, the yarn is not collected and thermally drawn in the heating zone to give

    Abstract: PURPOSE:A polyester yarn extruded out of the spinneret is once cooled down lower than its glass transition point, then allowed to run in a heating zone kept under specific conditions, drawn and taken up at a high speed to enable high-operability production of the titled fiber with reduced fluctuation in stress between filaments. CONSTITUTION:A polyester yarn extruded out of a spinneret is once cooled down lower than its glass transition point and drawn, as it is allowed to run through a heating cylinder 1 which satisfies equations: 0.8

    Abstract: PURPOSE:To obtain a shock absorbing air bag which is sophisticated in shock resistance and other kinds of durability and additionally light in weight by laminating rubber or resin on a ground fabric made of polyester fiber specifying various properties of polyester respectively through an adhesive. CONSTITUTION:An air bag used to protect a crew of a means of transportation from a shock at the time of collision is formed by laminating rubber or resin on a ground fabric made of polyester fiber through resorcinol, formalin, rubber latex and other adhesives. At this time, the polyester fiber is formed of polyester, more than 85% of whose repeated unit is ethylene terephthalate. And the intrinsic viscosity of the polyester is specified as more than 0.76, the density as more than 1.380g/cm , the strength as more than 6.5g/d, the ductility as more than 1.4%, the toughness as more than 120, the knot strength as more than 4.1g/d and the dry shrinkage percentage as less than 10% respectively.

    Abstract: PURPOSE: To obtain a polyester textile having a specific denseness excellent in color development and dropability, having dry and silky touch by interweaving polyester filaments including fine calcium carbonate and ruggedness on its surface with a weft comprising a hard twist yarn and a warp comprising a soft twist yarn. CONSTITUTION: This textile uses a polyester filament, as the warp and weft, including 1.0 to 5.0 wt.% of calcium carbonate powder having average particle size of 0.3 to 1.2 μm, and having ruggedness on the surface. The weft comprises a hard twist yarn having twist count of >=60% to the maximum twist count in the textile and the degree of denseness of >=1500, the warp comprises a soft twist yarn having twist count lower than that of the weft and the degree of denseness of >=250 in the textile. Textile excellent in color development and drapability, having dry and silky touch and free from sliminess is obtained.
