Abstract

PURPOSE:To provide a warp knitted fabric having soft feeling and suitable for inner wears such as shorts and girdle by placing a fine-spun twisted union yarn at least on one surface. CONSTITUTION:A knit gray fabric is produced by using a 4-yarn 2-gauge raschel machine placing a fine-spun twisted union yarn such as cotton sirospun yarn of count 100 and a 30de/10f nylon 66 multifilament yarn as the front and two kinds of 40de and 30de polyurethane elastic yarns as the back. The gray fabric is subjected to scouring relaxation, presetting, dyeing and final setting to obtain a warp knitted fabric having soft feeling, two-way stretchability, a short-fiber content of >=30% and at least one surface made of the fine-spun twisted union yarn.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft warp knitted fabric suitable for innerwear such as shorts and girdles, and more particularly to a soft warp knitted fabric suitable for shorts and girdles.

[0002]

2. Description of the Related Art As innerwear in which at least one side such as shorts made of 100% cotton yarn is composed of short fibers and the mixing ratio of the short fibers is 30% by weight or more, circular knitting is performed due to its soft texture and thin fabric thickness. It was a single place of the earth. In recent years, in addition to the soft texture and thin thickness of the fabric, the market needs are that the fabric form is firm, and if necessary, stretchability of 2 ways and power with a balance in the warp and weft directions is provided. What can be given is required, but the above circular knitted fabric has a problem to meet the market needs.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a warp knitted fabric that matches such market needs.

[0004]

DISCLOSURE OF THE INVENTION The present invention is a warp knitted fabric in which the mixing ratio of short fibers is 30% by weight or more, and a soft warp knitted fabric is characterized in that a spun and twisted yarn is used on at least one surface. Located on the ground. In the present invention, the spun and twisted yarn refers to a silospan composed of so-called short fibers and a silofil composed of short fibers and multifilament yarns. The materials of the short fibers and multifilament yarns used are cotton,
Natural fibers such as wool, hemp, silk, cupra, viscose rayon, polynosic rayon (especially average degree of polymerization of 500 to
600 is preferred. ) Etc., regenerated cellulosic fiber, LYOCELL; for example, Textile Society of Japan (Fiber and Industry), 48, [11] P. 584-591 (1992).
Corresponding to the product name TENCEL manufactured by Courtles Co., Ltd. ), Acetate, polyamide, polyester, acrylic (including polyacrylonitrile and a copolymer containing 40% by weight or more of polyacrylonitrile),
It is possible to use a combination of one or more synthetic fibers such as, and elastic fibers such as polyurethane.

Particularly for shorts and the like which are required to have hygroscopicity, silospan yarn of 100% cotton is suitable. The thickness of the spun twisted yarn may be appropriately selected according to the desired thickness and texture of the material, but 80 to 160 for shorts and girdle applications.
A count is preferable, and in tights and spats, a count of 20 to 100 is preferable.

The present invention is a warp knitted fabric using such a spun twisted yarn on at least one side. The optimum warp knitted fabric design is 4
Using a Russell knitting machine with more than one sheet, use spun and twisted yarns and multifilament yarns at the front, and insert two elastic fibers at the back, preferably using bare yarns and with different textures in the same wale. Used (a warp knitted fabric with one side composed of finely spun twisted yarn) or one in which elastic fibers (preferably using bare yarn) and finely spun twisted yarn are inserted in the back (composed of finely spun twisted yarn on both sides) Warp knitted fabric).

The warp knitted fabric of the above design has a short fiber mixture ratio of 3
5% by weight or more, and even 40 to 70% by weight, a high mixing ratio can be achieved, and the fabric has a soft texture and a thin fabric thickness. Furthermore, elastic fibers of 300 denier or less (when two or more elastic fibers are used, the total denier is Is 300 denier or less), it has a balanced 2-way stretch with soft power,
This is an epoch-making innerwear fabric that renews the image of conventional shorts and soft power girdle.

If desired, the elastic fiber may be an organic or inorganic compounding agent having a specific chemical structure, for example, a gas yellowing inhibitor, an ultraviolet absorber, an antioxidant, a fungicide, barium sulfate, magnesium oxide, Inorganic fine particles such as calcium silicate and zinc oxide, and anti-adhesive agents such as calcium stearate, magnesium stearate, polytetrafluoroethylene, and organopolysiloxane can be appropriately mixed.

The denier of the elastic fiber is 490 denier or less, preferably 20 to 300 denier, and the breaking elongation is preferably 50 to 800%. The elastic fiber may be a bare yarn or a composite yarn in which cotton yarn, synthetic fiber yarn or the like is covered by means such as covering. The multifilament yarn is preferably a synthetic fiber such as a polyamide fiber or a polyester fiber. As the polyamide fiber, a modified cross-section such as a triangle, a Y-shape, an L-shape or the like, or a hollow cross-section, or even a peripheral portion of the thread cross-section by weight reduction processing or the like is used. Those having a large number of irregularities can be used. or,
It may contain a matting agent, a stabilizer, an antistatic agent, etc. which are usually added to polyamide fibers.

Particularly preferred polyamide fibers are 3
There are spin take-up yarns and spin draw take-up yarns spun at a winding speed of 500 m / min or more, preferably 400 m / min or more, and high-strength yarns having a breaking strength of 7 to 10 g / d, the former being soft. Texture, the latter is further thinned. Further, as particularly preferable polyester fiber, 6000 m / min or more, preferably 65
Spin take-up yarn spun at a winding speed of 00 m / min or more, or 5000 m / min or more, preferably 5500
There is a spin draw take-up yarn spun at a winding speed of m / min or more, and both a soft texture is further achieved.

As for the thread thickness, the total denier is 2
0 to 100 denier, preferably 30 to 60 denier, and single yarn denier 0.1 to 10 denier, preferably 0.5 to 5 denier. The warp knitted fabric includes tricot and russell (satin net, power net), but russell, especially satin net, is preferable because the fabric thickness can be made thin and stretchability with power can be obtained.

The density of the warp knitted fabric is preferably 24 to 32 gauge (hereinafter referred to as) GG, more preferably 26 to 30 GG, and the basis weight is preferably 100 to 300 g / m ² .
