    Abstract: PURPOSE:To provide a polyester composition having excellent transparency, antistaticity and splipping property by compounding a polyester with a sulfonic acid metal salt compound or a sulfonic acid metal salt derivative containing a specific metal element in a specified amount, a polyoxyalkylene glycol, etc., in specific amounts, respectively. CONSTITUTION:100 pts.wt. of a polyester is compounded with 0.01-20 pts.wt. of a sulfaonic acid metal salt compound of the formula [R is alkyl, alkylaryl or aryl; M is alkali (earth) metal; m is 1 or 1/2] or a sulfonic acid metal salt derivative containing 0.001-10wt.%, preferably 0.01-5wt.%, of one kind or more of metal elements selected from alkali (earth) metals different from the metal element of the compound of the formula, Mn, Zn and Co, (B) 0.1-20 pts.wt. of a polyoxyalkylene glycol and (C) 0.001-5 pts.wt. of one kind or more selected from inorganic particles and organic particles having average particle sizes of

    Abstract: PURPOSE:To obtain a modifier which can improve the antistatic properties of a fiber, a film or the like obtained from a linear saturated polyester resin without causing them to undergo surface defects or loss of transparency by adding a specified metallic element to an alkali (alkaline earth) metal sulfonate. CONSTITUTION:A modifier for polyester resins is obtained by adding 0.001-10wt.%, based on component A, metallic element (B) selected from among an alkali (alkaline earth) metal other than the metallic element of component A, Mn, Zn and Co to a metal sulfonate compound (A) of the formula R-SO3M (wherein R is 5-40C, particularly 8-30C alkyl, an alkylaryl or an aryl, and M is an alkali metal of an alkaline earth metal, particularly K, Na or Li), e.g. sodium dodecylbenzenesulfonate,. 0.01-20 pts.wt. modifier is added to 100 pts.wt. polyester resin.

    Abstract: PURPOSE:To inhibit the sedimentation and agglomeration of particles and the deterioration of the color tone of a polymer, and to improve the whiteness, by adding a specific slurry at an arbitrary stage during the reaction of a dicarboxylic acid (derivatives capable of forming esters) with ethylene glycol. CONSTITUTION:10-80wt.% CaCO3 (a) having a mean particle diameter of 0.05-5mum, preferably 0.2-2mum, and a phosphorus compound (b) (e.g., phosphoric acid) with the molar ratio of the component (b) to the component (a) of 0.0005-0.2 are dispersed in ethylene glycol (c), and the dispersion is subjected to heat treatment at 50 deg.C - the boiling point to obtain an ethylene glycol slurry (C) containing the components (a) and (b). While a dicarboxylic acid (derivatives capable of forming esters) (A) is reacted with ethylene glycol (B), the component (C) is added at an arbitrary stage of the reaction of the components (A) and (B), with the amount of the compound (C) such that the content of the component (a) of the polyester which will be obtained will be 5-60wt.%, thereby producing the polyester. The obtained polyester is molded into a sheet, stretched biaxially 2.5-4.0-fold respectively and thermally fixed at 150 deg.C of over, thereby producing a white polyester film having a density of 0.9-1.3g/cm .

    Abstract: PROBLEM TO BE SOLVED: To provide a polyamide monofilament easy in compression deformation, excellent in bending abrasion resistance and bending fatigue resistance, and further excellent in antifouling property against gum pitch; usage of the monofilament to a textile to be mounted on a paper making machine; and an industrial textile such as a textile to be mounted on a paper making machine, represented by a paper making pressed felt having excellent water squeezing efficiency. SOLUTION: The polyamide monofilament has a compression deformation rate of >=5.6% and a number of times of bending abrasion needed before monofilament breakage of >=2.2×10 . The industrial textile is produced by using the monofilament at least in a part of the textile.
