It is the problem. The problem to be solved by the invention. In order to solve the above-mentioned problems in the past, the present invention provides a polyurethane elastic yarn and a stretchable knitted fabric, which are related to pantyhose fabrics * cotton rib knitting and wool fabrics. Polyacrylonitrile and other materials such as wool, cotton, silk, or used alone, can be shaped at low temperature, and show softness and suitability. Solution to Problem As a result of careful discussion, the inventors of the present invention have found the following as a guideline for solving the above-mentioned problems. Easy to say 1 is that it can be shaped at low temperature and exhibits softness and suitability. It focuses on the main structure of the raw silk: a crystalline region composed of the coarse fiber portion of the urethane, and suppresses the lateral growth of the fiber axis in this region. And the orientation of the fiber axis is disturbed, thereby achieving the above purpose. Specifically, in order to solve the above problems, the present invention adopts the following constitution. In other words, it must be a polyurethane silk that is characterized by meeting the following conditions: ⑴ ～ ⑶: ⑴ In small-angle X-ray scattering measurement, the angle formed by the half-width of the maximum peak intensity of the angle scan is 60 Above degree: 角度 In the small-angle X-ray scattering measurement, the angle formed by the half-width in the equatorial direction is 2.5 degrees or less; ⑶ In the thermal stress measurement, the maximum shrinkage stress peak temperature is below 1 35 ° C This paper scale Applicable to China National Standard (CNS) Α4 specification (2 i Ο X 297 mm) ---------- Clothing-- (Please read the precautions on the back before filling this page) Order the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Consumer Cooperative: 2612 A7 B7 V. Description of the invention (3) It is preferred to use the above polyurethane elastic yarns with a maximum shrinkage stress peak temperature of 105 / C or less in thermal stress measurement: at small angle X-rays In the scattering measurement, the above-mentioned polyurethane elastic yarn with an angle formed by the half-width in the equatorial direction of 0.8 degrees or more and 1.5 degrees or less: The dry heat setting property (PSD120) at 1 20 ° C is 65¾ or more, and 105t ： Damp heat setting (PSW105) is more than 75% The above-mentioned polyurethane elastic yarn: in the thermal stress measurement, the above-mentioned polyurethane elastic yarn with a maximum shrinkage stress of 10 mg / denier or less: in the repeated stress measurement at 300% elongation, relative to The above-mentioned polyurethane elastic yarn with 150% tensile stress and 20% or less of the back stress: and the above-mentioned polyurethane elastic yarn obtained by melt spinning. In addition, the invention concerning a stretchable knitted fabric is characterized in that it is a stretchable knitted fabric formed by alternately knitting the above-mentioned polyurethane elastic yarn and a thermoplastic synthetic fiber.

First, the angle formed by the half-width of the maximum peak intensity of the required positioning angle scan in the small-angle X-ray scattering measurement of the polyurethane elastic yarn of the present invention is based on the Chinese paper standard (CNS) A4 ( 210X297 mm) 4 5 26 12 a? B7____ 5. Description of the invention (4) The degree is above 60 degrees. In the small-angle X-ray scattering measurement here, the angle formed by the half-width of the maximum peak intensity of the positioning angle scan is the angle formed by the center of the refraction image photograph obtained by performing the positioning angle scan and the half-width of the maximum peak intensity. If it is less than 60 degrees, the orientation of the crystalline region mainly composed of the coarse fiber portion is good, and the stretching force is too large, which makes it difficult to obtain softness and suitability when the product is worn. In the present invention, the orientation of the crystalline region is deliberately disturbed, so that when the polyurethane elastic yarn produced is strained in the direction of the fiber axis, strain deformation can be generated at a lower stress. It is preferably 75 to 85 degrees. In addition to the above characteristics, it also has a structure that the angle formed by the half width in the equatorial direction is less than 2.5 degrees in the small-angle X-ray scattering measurement. The angle is the apex angle of the equilateral triangle formed by the half width of the equatorial direction in the refraction image and the center of the camera's length. If it is more than 2.5 degrees, the growth in the crystalline region, especially in the transverse direction of the fiber axis direction, will become incomplete, and the strength and elongation of the obtained yarn will be lowered, causing practical problems. It is preferably 0.8 ° to 2.5 °, and more preferably 0.8 ° to 1.5 °. If it is lower than 0.8 degrees, in the crystalline region formed by the coarse fiber portion, especially in the transverse direction of the fiber axis direction, its expansion will increase, and the stretching force will become too large, which will make it difficult to obtain softness when the product is worn. Suitability. In the thermal stress measurement of the polyurethane elastic yarn of the present invention, the required maximum shrinkage stress peak temperature is below 135 ° C. If it is higher than 135 ° C, in the case of combination with polypropylene gauze, wool, cotton, silk and other materials, the paper size of these materials applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ^^ 1 m ^ ^^ 1 ^^^ 1 ml I ^ [1-II 1 «.

The dry heat settability (PSD 120) of the polyurethane rayon silk of the present invention at 120 ° C is 65% or more, and the wet heat settability (PSW105) at 105 为 is 75% or more. Because if it is a polyurethane elastic yarn with such characteristics, when it is combined with polypropylene, wool, cotton and silk and other materials, under the appropriate processing conditions of these materials, it can be Fully settable. In other words, if the PSD 120 is lower than 65¾, in the subsequent processing steps, under the heat treatment of the predetermined forming step and the like, its heat setability will be poor, and the pre-prepared softness will not be obtained.
