Abstract: PROBLEM TO BE SOLVED: To solve a problem that a highly oriented fiber is excessively oriented to cause fuzzes, the breakage of the fiber, or the like, when drawn and false- twisted at a higher take-up speed than conventional take-up speeds. SOLUTION: This polyester raw fiber for drawing and false twisting is characterized by containing a phosphorus compound represented by the general formula (1) or (2) in an amount of 20 to 1,000 ppm as phosphorus atoms and having a birefringence of 0.08 to 0.16.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyester at a higher productivity. SOLUTION: In a method for producing a polyester by the polycondensatin of a product formed by the esterification of a dicarboxylic acid with a diol, the molar ratio R1 (diol/dicarboxylic acid) of the diol to the dicarboxylic acid charged to be subjected to esterification is set at 1.10 or lower, and water in an amount of 10 wt.% or lower of the sum of the dicarboxylic acid and the diol is added when the mixture of the acid and the diol is prepared, thus enabling a polymer having a high degree of polymerization to be obtained in a shorter time.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester composition good in thermal stability, transparency and polymer color tone, excellent in molding/forming processabilities, and useful for fibers, etc., by including specific phosphorus compound(s) and through polycondensation reaction without decline in the reactivity. SOLUTION: This polyester composition is obtained by including phosphorus compound(s) of formula I and/or II [R1 and R2 are each H, a 1-15C alkyl, phenyl, or the like; R3 is phenyl or a trivalent organic group; R4 and R5 are each carboxy, a hydroxyalkyl, or the like; R6 is (CH2)n (n is 2-4)] so as to be 20-1,000 ppm in the content based on the polyester polymer (calculated as phosphorus atom); wherein if an aromatic dicarboxylic acid or an ester-forming derivative thereof and a diol, or a low-molecular polyester oligomer is used as a starting material, it is preferable to incorporate the phosphorus compound(s) in the starting material.

Abstract: PROBLEM TO BE SOLVED: To provide the subject fibers having desired high dimensional stability, having high strength and excellent in durability by containing respectively a specific amount of a nickel compound and an antimony compound. SOLUTION: A polyester containing a nickel compound (e.g. nickel acetate) in an amount of 2-120ppm reduced to a nickel metal and an antimony compound (e.g. antimony trioxide) in an amount of 150-450ppm reduced to an antimony metal is fiberized and a total amount of intermediate elongation (elongation corresponding to 4.5g/d stress in a stress-strain curve; defined in this invention) and dry heat shrinkage (at 150 deg.C) is made to be 8-12% to obtain the objective polyester fiber.

Abstract: PURPOSE:To obtain the titled polyester which can give a high-strength and high-Young's modulus fiber even by a super-high-speed spinning process, by adding a small amount of a specified phosphonic acid compound in the stage before completion of the polycondensation reaction in the production of a polyester. CONSTITUTION:Phosphoric acid compounds of formulas I and/or II [wherein R1 is phenyl or a 1-4C alkyl, R2 and R3 are each ydroxyl group, a 1-15C alkyl, phenyl or the like, R4 is (CH2)n and n is 2-4], e.g., phenylphosphonic acid or a cyclic ester thereof with ethylele glycol) is prepared. A polyester for high-speed spinning is obtained by adding 0.01-1wt%, based on the acid component which constitutes the polyester, phosphonic acid compounds of formulas I and/or II to the reaction system in the stage before completion of the polycondensation reaction in producing a polyester by using terephthalic acid (esterifiable derivative) and etylene glcyol as principal materials.
