Abstract: PROBLEM TO BE SOLVED: To obtain the subject conjugate fiber having high commercial value, gloss, dry feeling and feeling and useful for a sports clothing, etc., by using a hydrophilic component and a fiber-forming property as constituting components and having respectively prescribed humidity-absorbing and releasing parameter (ΔMR) and a flatness degree. SOLUTION: This fiber is a core-sheath conjugate fiber comprising a hydrophilic component 1 such as a polyetheresteramide-based compound and a polyetherester-based compound and a fiber forming polymer 2 such as polyethylene terephthalate as constituting components, and has >=1.0 % of ΔMR and 1.05-3.0 of flatness degree of the formula: flatness degree = (long distance in fiber cross section/short distance in fiber cross section). Preferably, a compound having ΔMR>=8% is used as the hydrophilic component, and the hydrophilic component is used as one component and a conjugate fraction is 5-90 wt.%, then a hollow part 3 is in the conjugate fiber structure, thus hollow fraction is 1-20%.

Abstract: PROBLEM TO BE SOLVED: To stably produce a stretch back yarn having a bulkiness like a natural fiber, high bulkiness and stretchability and good crispness and toughness while solving the defects of conventional technique. SOLUTION: The fiber is a modified cross-section side-by-side conjugate polyester fiber composed of (A) a high-shrinkage polyester component consisting of a polypropylene terephthalate containing ≥85 mol% propylene terephthalate repeating unit and (B) a low-shrinkage polyester component consisting of a polyethylene terephthalate containing ≥85 mol% ethylene terephthalate repeating unit. The conjugate joint face between the high-viscosity polyester component A and the low-viscosity polyester component B in the cross-section of the fiber is constituted by two or more different groups of single fibers and all single fibers have the same conjugation ratio.

Abstract: PURPOSE:To provide polyester fiber which is suitably useful over a wide range of garment applications because it has fine roughness on the fiber surface and stick slip properties, shows high-quality appearance, dry fabric hand and gives comfortable feeling on clothing. CONSTITUTION:Titanium dioxide particles of 30-150nm primary particle size on the average or fine particles of alumina or zirconium oxide of 1-1,000nm average primary particle size are added to poly(ethylene terephthalate) in an amount of 0.3-10wt.%, mixed in an extruder, then melt-extruded into filaments. The filaments are woven or knitted into cloth, which is subjected to alkali- thinning treatment to form fine unevenness on the fiber surface whereby the cloth of polyester fibers having more than 0.020g/de stress difference DELTAf in the stick slip curve is produced.
