Abstract: PURPOSE:To obtain the fiber excellent in a latent crimping ability suitable for obtaining spun yarns, woven fabrics, knitted fabrics or non-woven fabrics excellent in elasticity and elongation recovery by specifying the expressed crimp number of the composite fiber on its thermal treatment under non-load, the composite fiber comprising a specific copolyester and PET. CONSTITUTION:The composite fiber comprises (A) a copolyester consisting mainly of ethylene terephthalate units copolymerized with 2-7mol.% of 2,2- bis[4-(2-hydroxyethoxy)phenyl]propane of the formula and 5-13mol.% of isophthalic acid and (B) a polyester substantially comprising ethylene terephthalate units. The expressed crimp number of the composite fiber on its thermal treatment under non-load at 180 deg.C is >=50 crimps/5mm, preferably

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester fiber spinnable in high operability over the whole spinning process and having high antistaticity by applying a lubricant containing respectively specific phosphoric acid ester potassium salt, alkylamine ethylene oxide adduct and alkyl ether. SOLUTION: This polyester fiber is coated with 0.05-0.40wt.% of a lubricant containing (A) 30-50wt.% of a phosphoric acid ester potassium salt having an 8-12C saturated aliphatic hydrocarbon group, (B) 5-15wt.% of an alkylamine ethylene oxide adduct having a molecular weight of 200-1,000 in terms of polyoxyethylene and (C) 40-60wt.% (A+B+C is 100wt.%) of an alkyl ether having a molecular weight of

Abstract: PURPOSE: To obtain the subject fibers prevented from scum development during its spinning process and excellent in performance after its resin finishing, by imparting the original fibers with a specific lubricant. CONSTITUTION: Polyester fibers for industrial materials >=0.5 denier in single fiber fineness is imparted with 0.05-0.4owf% of a lubricant comprising (A) 50-70wt.% of a phosphoric ester potassium salt having average 16-22C saturated aliphatic hydrocarbon group, (B) 10-20wt.% of paraffin wax, (C) 10-15wt.% of cationic and/or anionic surfactant(s) and (D) 4-15wt.% of surfactant(s) of formula I (R1 is a 10-14C aliphatic hydrocarbon group; (l+m)=5-15) and/or formula II (R2 is a 8-10C aliphatic hydrocarbon group; (n) is 5-10). This lubricant is
