    Abstract: A process for producing polyester fiber highly suitable for a raw yarn for a woven or knitted fabric, having a residual elongation of not higher than 60%, a Young's modulus of 60 to 100 g/d, a boiling water shrinkage of 4 to 10% and a dry heat shrinkage of 5 to 12%, the peak stress temperature in a dry heat shrinkage stress curve of said fiber being lower than 100 DEG C. The process comprises melt spinning a thermoplastic polyester through a spinneret into a filament and taking up the filament after solidifying the spun filamentary polymer, characterized in that the whole process from spinning through take-up is carried out without heating the filament, the filament is subjected to stretch treatment at a stretch ratio of not more than 20% after the solidification of the filament but before take-up, and take-up is carried out at a take-up speed of not less than 5,000 m/min.

    Abstract: PURPOSE:To obtain a piece of waterproof canvas which has bulky feeling and is superior in durability, by a method wherein polyester filament is an aggregate where a number of pieces of single yarn are specific, the pieces of single yarn each possess a noncircular sectional form, confounded by forming a loop, base cloth is formed by weaving a polyester filament, the surface is coated with vinyle chloride resin and processed. CONSTITUTION:At least 85% of the whole repeating unit of a molecular chain is a polyester filament comprised of a polyethylene terephthalate and the polyester filament is an aggregate comprised of a number of pieces of single yarn of 90-300 pieces. The pieces of single yarn each possess a noncircular sectional form which is confounded by forming a loop, base cloth is formed by weaving the polyester filament and the title canvas is constituted by coating the surface of base cloth with vinyl chloride resin at 200-350g/m . When the pieces of the single yarn are fewer than 90 pieces, binding force among the pieces of the single yarn is lowered. When they are more than 300 pieces, since opportunities where a movement of the pieces of the single yarn is restricted become many, confounding or a loop by a fluid nozzle is reduced extremely.

    Abstract: PURPOSE:To obtain a safety net having knitting strength, impact absorption resistance, flame retardance, light resistance, etc., by knitting a specific spun- dyed polyester yarn consisting essentially of polyethylene terephthalate, CONSTITUTION:Synthetic yarn of spun-dyed polyester having >=90mol% whole repeating unit of molecular chain comprising polyethylene terephthalate is knitted by raschel knitting machine into mesh woven fabric, which is heat-treated. The spun-dyed polyester yarn has >=0.7 intrinsic viscosity, >=7.0g/d strength at break, >=15% elongation at break, >=110 toughness, >=4.5g/d loop strength, >=45% light resistance and contains 0.3-1.0wt.% calculated as phosphorus element amount of bifunctional phosphorus compound.

    Abstract: PURPOSE:To obtain the subject fiber, excellent in dimensional stability and suitable as a reinforcing material for rubber structures in tire cords, V-belts, hoses, etc., by doubling plural first twisted yarns having a specific intrinsic viscosity, amorphous orientation function, strength, etc., and finally twisting the doubled yarns. CONSTITUTION:A polymer, containing polyethylene terephthalate in an amount of >=90mol% in the total number of recurring units and having 0.97-1.15 intrinsic viscosity is melt spun, passed through a high-temperature atmospheric zone preferably at 205-350 deg.C, cooled and then drawn to provide a fiber having
