Problems solved by technology

There is a problem in these leg products, that is, in a slightly hot season such as early summer, you will feel cool only at the moment of wearing, but in a hot environment that is an environment that sweats due to long-term wearing or walking. When wearing it, you will sweat, become stuffy, and feel extremely uncomfortable, so it is not suitable for hot environments such as midsummer

Embodiment 1

[0109] A 21dtex covered elastic yarn was produced by covering the raw yarn 13dtex / 7 filaments of the polyamide fiber with the stretch ratio of the elastic yarn 3.0 and the twist number of 1700T / m on the elastic yarn 22dtex (trade name ROICASF: manufactured by Asahi Kasei Co., Ltd.). Using this covered elastic yarn, use a pantyhose knitting machine with 352 needles to adjust the size of the stitches on the thigh and calf so that the dimensional ratios, stretched lengths in the width direction, and thighs are set in Table 1. The number of courses of the part is knitted from the part equivalent to the waist of the pantyhose to the toe. Here, the part corresponding to the shorts part is knitted by alternating covered elastic yarn and polyamide fiber processed yarn 78dtex / 24 filaments, and the size of the loop is gradually reduced from the crotch only by the covered elastic yarn. Weave to the toe part, use 2 braided fabrics, perform sewing of the shorts part and sew the toe part. ...

Embodiment 2～5、 comparative example 1～2

[0111] In Example 1, pantyhose (Examples 2 to 3, Comparative Example 1) in which the size ratio was changed by adjusting the size of the loops of the thigh and calf when the legs were knitted were produced, and Pantyhose in which the number of courses of the thigh was changed (Examples 8 to 9, Comparative Example 4), and pantyhose in which the concentration of the silicon processing agent was changed to 8% owf (Example 4) were produced. Pantyhose (Example 5) in which the concentration of the silicon processing agent was changed to 3% owf was manufactured, and pantyhose (Comparative Example 2) in which the concentration of the silicon processing agent was changed to 1% owf was manufactured, and Wear test etc. The results are shown in Table 1.

Embodiment 6

[0113] 19dtex (trade name ROICA BZ: manufactured by Asahi Kasei Co., Ltd.) is used to cover the raw yarn 8dtex / 5 filaments of polyamide fiber with the stretch ratio of elastic yarn 3.0 and the number of twists 1900T / m to make a covered elastic yarn of 15dtex . Using this covered elastic yarn, a pantyhose knitting machine with 368 needles is used to knit from a portion corresponding to the waist of the pantyhose to the toe. Here, the part corresponding to the shorts part is knitted by alternating covered elastic yarn and polyamide fiber processed yarn 78dtex / 24 filaments, and the size of the loop is gradually reduced from the crotch only by the covered elastic yarn. Weave to the toe part, use 2 braided fabrics, perform sewing of the shorts part and sew the toe part. Then, it is put into a drum dyeing machine to dye polyamide fibers. At the end of the dyeing process, a silicon-based processing agent (Meishi Licon ASE68 (manufactured by Meisei Chemical Industry Co., Ltd.)) is pu...

Abstract

The present invention provides a leg product that feels cool and pleasant during both wearing and exercising. This leg product comprising a tubular knitted fabric, in which the entire course of a legpart is knitted in a jersey stitch by using coated elastic yarns comprising elastic yarns and synthetic fibers, is characterized in that: the wale number in the circumferential direction is 340-400 wale; the size ratio is 1.10-1.40, as calculated using the following equation (1): size ratio = (width-direction elongation under a load of 3 kg at the 1 / 4 position from a crotch portion of the leg part) / (width-direction elongation under a load of 3 kg at the 3 / 4 position from the crotch portion of the leg part); and the stress ratio is 0.35-0.60, as calculated using the following equation (2): stress ratio = (stress (N) of backward path at the 50% point) / (stress (N) of forward path at the 50% point), where the stress of a forward path and the stress of a backward path are measured at the 50% point of the third repetition of an elongation / contraction process that is repeated three times, said elongation / contraction process involving elongating the knitted fabric up to 80% in the radial direction at the 1 / 2 position from the crotch portion of the leg part, and then returning the knitted fabric to the original length thereof.

Description

technical field [0001] The invention relates to a leg product which can feel cool when worn in a hot environment. Background technique [0002] Conventionally, with regard to leg products such as cool pantyhose and leggings that use elastic yarns that cover from the crotch to the ankles or toes, there are leg products that are hygroscopic by using polyamide fibers and the like. When using synthetic fibers to suppress the stuffy feeling, leg products using special-shaped cross-section yarns of polyamide fibers to obtain a cool feeling (for example, refer to the following patent document 1), and also impart coolness to the touch by using full-dull yarns Sensitive leg products (for example, refer to the following patent document 2). In these leg products, there is a problem that in a slightly hot season such as early summer, you feel cool only at the moment of wearing, but in a hot environment that is an environment where sweating occurs due to long-term wearing or walking.
