Problems solved by technology

However, in these braids, various techniques have been shown for circular knitting, but for warp knitting, since the loop (loop) structure is specific, the braids are particularly prone to crimping, and it has not been found in the past that the cross-knitted fibers Clothes that are used directly after the warp knitted fabric made of cellulose fiber is cut. In Patent Document 1, there is no specific embodiment disclosed about the warp knitting of interwoven cellulose fiber and elastic yarn.
[0004] In this way, in the warp knitted fabric with stretchability formed by interweaving cellulose fibers and elastic yarns, it has not been found that it has a cool feeling when worn, excellent moisture absorption, and sweat absorption, and it is directly made into clothes without sewing after cutting. woven fabrics that can be cut without processing

Embodiment 1

[0102] Using a 28-gauge tricot machine, nylon 33dt / 24 filaments are stretched and warped 100% on the front bar, and cupro fibers (trade name bemberg: manufactured by Asahi Kasei Co., Ltd.) are drawn on the middle bar. 33dt / 24 filaments are 100% elongated and warped, elastic yarn 44dt (trade name ROICA CR: manufactured by Asahi Kasei Co., Ltd.) is 100% elongated and warped on the rear bar, and all 3 bars are stretched toward the entire bar. threading, front bar with figure 2 The needle weave shown is woven, and the middle bar is figure 1 Warp weave shown, rear bar ends with Figure 8 The organization shown is organized.

[0103] Front Bar: Tissue 10 / 23 / /

[0104] Middle bar: Tissue 10 / 12 / /

[0105] Rear Bar: Organization 10 / 12 / 10 / 23 / 21 / 23 / /

[0106] The knitted fabric was relaxed and refined by a continuous refiner, and then pre-set at 190° C. for 1 minute, and nylon and cellulose fibers were dyed by a flow dyeing machine. Fill softening agent after dyeing, under the c...

Embodiment 2～5、 comparative example 1

[0108] In embodiment 1, change the tissue of the elastic yarn of rear part bar, produce the braid (embodiment 2: Figure 4 , Example 3: Figure 5 , Example 4: Image 6 , Example 5: Figure 7 ), in addition, a braided fabric (comparative example 1) was manufactured with the structure of the rear bar as 12 / 10 / / . The properties of the prepared braids were evaluated. The results are shown in Table 1 below.

[0109] The warp knitted fabrics obtained in Examples 2 to 5 do not cause curling at the cut portion of the knitted fabric, and can be made into products without processing after cutting, and the cool feeling, elongation, wearing feeling, and sewing process Sex is also excellent.

Embodiment 6

[0111] Using a Tricot warp knitting machine with a gauge of 32, the polyester 22dt / 6 filaments are 100% elongated and warped on the front bar, and the cupro (trade name bemberg: manufactured by Asahi Kasei Co., Ltd.) is warped on the middle bar. ) 33dt / 24 filament 100% elongated and warped, elastic yarn 22dt (trade name ROICA SF: manufactured by Asahi Kasei Co., Ltd.) is elongated and warped by 100% on the rear bar, / / Braided, the middle bar and the rear bar are image 3 organized by.

[0112] Front Bar: Tissue 01 / 21 / /

[0113] Middle bar: tissue 10 / 12 / 10 / 12 / 23 / 21 / 23 / 21 / /

[0114] Rear bar: tissue 10 / 12 / 10 / 12 / 23 / 21 / 23 / 21 / /

[0115] The knitted fabric was relaxed and refined using a continuous refining machine, and then pre-set at 190° C. for 1 minute, and nylon and cupro fibers were dyed using a flow dyeing machine. Fill softening agent after dyeing, under the condition of 170 ℃ and 1 minute, carry out finishing setting, have made warp knitted fabric.

Abstract

The present invention provides a warp knitted fabric that is excellent in stretchability and cool feeling when worn, does not cause curling at the cut portion of the knitted fabric, and can be processed after cutting. The present invention is a warp-knitted fabric woven from synthetic fibers from the first bar, cellulose fibers from the second bar, and elastic yarns from the third bar, and is characterized in that the warp-knitted fabric The number of crossing points where the sinker loops of the synthetic fiber and the sinker loops of the elastic yarn intersect between the spanning wales existing in 1 complete course is relative to the number of crossing points that exist in the 1 complete course and spanning The ratio of the number of sinkers of the synthetic fibers between the wales is 50% or less.

Description

technical field [0001] The present invention relates to a warp-knitted fabric interwoven with cellulose fibers and elastic yarns, which has an excellent cool feeling when worn in a hot environment. Background technique [0002] Conventionally, as clothes that directly contact the skin such as underwear and sportswear worn in summer and other hot environments, clothes that are excellent in cool feeling, hygroscopicity, and sweat absorption by cross-knitting cellulose fibers are known. In particular, the following proposals are proposed: Disclosed is a woven fabric that does not feel sticky, moist, or cold even when the cellulose fiber content, the surface shape of the woven fabric, and the like are determined in particular, even when sweating due to stuffiness or exercise. However, in recent underwear and sportswear, knitted fabrics made of cross-knitted elastic yarns are often used to impart stretchability to clothes. In knits made of cross-knitted elastic yarns, the thickne...
