  However, the conventional Raschel warp knitted fabric has a problem of poor flatness such as curling (rolling) when the end portion is thin. In addition, for example, when used on a shorts hem portion (contact portion with a leg portion) of a female underwear, there is a problem that an underwear line can be seen.

  In order to solve the above-described conventional problems, the present invention provides a Raschel warp knitted fabric that does not curl at the end of the knitted fabric, has good flatness, and does not require end treatment.

  The Raschel warp knitted fabric of the present invention is a Raschel warp knitted fabric including a base knitting portion and a warp insertion portion, and the warp insertion portion is present at at least one end in a direction perpendicular to the knitting direction of the base knitting portion, The warp insertion portion is knitted with a warp insertion yarn, a chain knitting yarn, and a jacquard texture yarn, and the warp insertion yarn is thicker than each of the chain knitting yarn and the jacquard texture yarn.

  In the present invention, the warp insertion portion is present at at least one end in a direction orthogonal to the knitting direction of the base knitting portion, the warp insertion portion is knitted with warp insertion yarn, chain knitting yarn, and jacquard texture yarn, Further, by being thicker than each of the chain knitting yarn and the jacquard texture yarn, it is possible to provide a Raschel warp knitted fabric that prevents curling of the warp insertion portion to provide flatness and does not require the end treatment of the knitted fabric. When this warp knitted fabric is applied to, for example, women's underwear shorts, the base knitting part can be arranged at the main part of the shorts and the warp insertion part can be arranged at the shorts hem part (contact part with the leg part). As a result, the skirt of the shorts is flat as it is, the folding process is unnecessary, and the underwear line does not appear, which is a design advantage. In addition, when a stretchable yarn is used as a warp insertion yarn, it is possible to improve the wearing feeling of the hem portion by the elongation and power of the stretchable yarn in addition to the above-mentioned design advantages.

FIG. 1 is a schematic explanatory view of a Raschel warp knitted fabric according to an embodiment of the present invention. FIG. 2 is a schematic side view showing a main part of a double raschel knitting machine used for manufacturing a raschel warp knitted fabric according to an embodiment of the present invention. FIG. 3 is a structural diagram of a warp insertion portion of a Raschel warp knitted fabric according to an embodiment of the present invention.

  The present invention is a Raschel warp knitted fabric in which a warp insertion portion is present at least at one end in a direction orthogonal to the knitting direction of the base knitting portion. Raschel warp knitted fabric has elasticity and is suitable for women's underwear because it fits the body. The warp insertion portion may be present at one or both ends of the base knitted fabric. The base knitted fabric may have no pattern or a knitted pattern (knitted pattern). The warp insertion portion is knitted with warp insertion yarn, chain knitting yarn, and jacquard texture yarn. In the following description, “raschel warp knitted fabric” is also simply referred to as “warp knitted fabric”.

  The warp insertion yarn is thicker than each of the chain knitting yarn and the jacquard texture yarn. As a result, the warp insertion portion becomes flat and curling can be prevented. Preferably, the warp insertion yarn is thicker than the total fineness of the chain knitting yarn and the jacquard texture yarn. As a result, the warp insertion portion is further solid and flatness is enhanced. The length and width of the base knitted fabric can be arbitrarily determined depending on the intended clothing. For example, the length and width can be about 10 cm to 3 m. The width of the warp insertion portion is preferably 5 to 50 mm, more preferably 10 to 30 mm.

  The warp insertion yarn is preferably a stretch yarn having a synthetic fiber filament yarn covered on the surface of an elastic yarn. In this way, in addition to the effect of not providing an underwear line, the stretch feeling of the elastic yarn and the power of the hem can be improved by using the elastic yarn.

  The base knitting portion is preferably knitted with chain knitting yarn and jacquard texture yarn. When putting a knitted pattern (knitted pattern), the basic structure and the pattern are knitted by changing the jacquard textured yarn. The pattern is expressed by changing the swing width of the jacquard texture yarn. Similarly, holes can be knitted.

  The chain knitting yarn is preferably a woolen nylon yarn, and the jacquard texture yarn and the warp insertion yarn are preferably stretch yarns in which a wooly nylon yarn is covered with a urethane yarn. With such a thread use, the feeling of wearing as an underwear is high, and in addition to the effect that the warp insertion portion does not give out the underwear line, the feeling of wearing the hem can be improved by the extension and power of the elastic yarn. .

  This will be described below with reference to the drawings. In the following drawings, the same reference sign means the same thing. FIG. 1 is a schematic explanatory view of a Raschel warp knitted fabric 10 according to an embodiment of the present invention. The Raschel warp knitted fabric 10 has a warp insertion portion 12 formed at one end in a direction orthogonal to the knitting direction A of the base knitting portion 11. The portion between the base knitting portion 11 and the warp insertion portion 12 in FIG. 1 is merely a difference in whether or not there is an insertion yarn, only by inserting the insertion yarn into the base structure.
