Abstract: PURPOSE:To obtain the titled polymer having excellent moldability, etc., by carrying out esterification reaction in the presence of an organic Sn compound catalyst and adding a polycondensation reaction catalyst to the reaction system under a specific condition, thereby remarkably decreasing the content of minute foreign materials originated from the organic Sn compound in the polymer. CONSTITUTION:A dicarboxylic acid component composed mainly of terephthalic acid and a diol component composed mainly of 1,4-butanediol are subjected to esterification reaction in the presence of an organotin compound (e.g. butyltin hydroxyoxide) as an esterification reaction catalyst. After the completion of the esterification reaction, a polycondensation reaction catalyst (e.g. tetraethyl titanate) is added to the reaction system under agitation at a circumferential speed of >=4m/sec, preferably >=5m/sec to effect the polycondensation reaction and obtain the objective polymer. The above polycondensation reaction catalyst is preferably added to the system in the form of a diol solution, etc.

Abstract: PROBLEM TO BE SOLVED: To obtain cosmetic cotton which has an excellent water absorptivity an water resistance an has stiffness and voluminous feel by incorporating polyester staple fibers and/or acrylic staple fibers at a specific ratio into the non- woven fabric of the cosmetic cotton consisting of an inside layer made of the non-woven fabric and an external material including the inside layer. SOLUTION: The cosmetic cotton used at the time of removing a user's makeup, etc., consists of the inside layer 1 made of the non-woven fabric an the exterior material 2 including the inside layer 1. In such a case, the polyester stapes fibers and/or the acrylic stapes fibers are incorporated at >=20wt.% into the non-woven fabric. The polyester stapes fibers are particularly preferably polyethylene terephthalate stapes fibers, for which the use of their copolymer and denatured matter is possible as well. Cotton is preferably incorporated into the non-woven fabric. The content of the cotton is recommended to be 5 to 80wt.% over the entire part of the nonwoven fabric. Further, the incorporation of binder stapes fibers, such as core and sheath type polyester stapes fibers and unstretched polyester yarn, into the non-woven fabric is possible as well.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester fiber excellent in water permeability and high- order processability by applying an inorganic salt of an alkylsulfonic acid, an inorganic salt of an alkylsarcosine and/or an inorganic salt of an alkyloylsarcosine thereto. SOLUTION: This polyester fiber comprises an inorganic salt of an alkylsulfonic acid, an inorganic salt of an alkylsarcosine and/or an inorganic salt of an alkyloylsarcosine applied thereto. The polyester fiber is obtained by applying the inorganic salt of the 8-22C alkylsulfonic acid such as sodium oleylsulfonate in an amount of 0.02-0.3wt.% based on the fiber weight and the inorganic salt of the 8-22C alkylsarcosine such as sodium octylsarcosinate and/or the inorganic salt of the 8-22C alkyloylsarcosine such as sodium caproylsarcosinate in an amount of 0.01-2wt.% based on the fiber weight to a tow of the polyester fiber and then cutting the resultant tow to a prescribed length. Thereby, the resultant polyester staple fiber is excellent in water permeability.
