摘要： PROBLEM TO BE SOLVED: To provide a sea-island type composite cross-section fiber capable of suppressing separation at a composite interface and substantially improving a fluff and thread breakage, etc., and an ultra fine polyamide fiber obtained by dissolving and removing a polyester included in the sea-island type composite fiber.SOLUTION: The sea-island type composite cross section fiber uses an alkali easily leachable polyester having a main repeating unit formed of ethylene terephthalate and comprising 2.0-5.5 mol% of an isophthalic acid component including a metal sulfonate group and 3.0-6.0 mol% of an adipic acid component to a total acid component as a sea component, and a polyamide as an island component. In the sea-island type composite cross section fiber, a unit reaction rate of terephthalic acid caused by an ester/amide exchange reaction is 0.0005-0.0025%/mm.

摘要： PROBLEM TO BE SOLVED: To provide an island-in-sea type conjugated cross-section fiber in which peeling of a composite interface may be suppressed and fluff, thread breakage and the like may be largely improved, and to provide an extra fine polyamide fiber obtained by dissolving and removing polyester included in the island-in-sea type conjugated cross-section fiber.SOLUTION: An easily alkali soluble polyester comprises: a principal repeating unit of ethylene terephthalate; an isophthalic acid component having a metal sulfonate group of 2.0 to 5.5 mol% based on the whole acid component; and an adipic acid component of 3.0 to 6.0 mol% based on the whole acid component. An island-in-sea type conjugated cross-section fiber comprises: the easily alkali soluble polyester including 3 to 10 ppm of a polyester-soluble titanium compound in terms of titanium element and 5 to 40 ppm of a phosphorus compound in terms of phosphorus element as a sea component; and a polyamide as an island component.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing an extremely fine synthetic fiber composed of multiple fiber yarns capable of taking the multiple fiber yarns by one spinneret, also having less unevenness in quality among fiber yarns and stable in the point of workability and operability in producing the extremely fine synthetic fiber by a melt spinning, and to provide a device for producing the same. SOLUTION: The method for producing the extremely fine synthetic fiber by melting a thermoplastic resin and ring form-cooling a group of fiber yarns Y having ≥3 fiber yarns of the total number of fiber yarns ejected as a ring form from the spinneret by using a ring-formed cooling device from the outer circumference of the ejected fiber yarn group to center satisfies the following conditions (A) to (D): (A) The ejection holes 2 are arranged in one row and as a ring form, or in a plurality of rows on concentric circles. (B) The arrangement is divided by dividing bands. (C) From an optional point in an area (spinning area) containing the ejection holes within the divided arrangement on a perpendicularly downstream line, each of the fiber yarns Y ejected from the ejection hole is imparted with an oil agent. (D) The fiber yarns are imparted with the oil agent at the right angle or approximately crossing at right the angle and toward the same direction to the perpendicularly downstream line.
