Description

  The present invention relates to a warp knitted elastic knitted fabric having an anti-slip function.

  Many elastic knitted fabrics used for bandages, supporters, various clothing, and the like are required to have an anti-slip function with contact objects such as skin. As a means of imparting a non-slip function to various knitted fabrics, a method of applying a rubber material to the surface in a dotted or linear manner is well known, but a non-slip function with the skin like a bandage or a supporter. Is not preferable because the rubber material is not soft to the touch.

  As an elastic knitted fabric having an anti-slip function in consideration of the good touch, a loop knitted fabric formed of two or more elastic yarns on the same knitted fabric (for example, refer to Patent Document 1) and circular knitted stockings are targeted. There is one in which an elastic yarn is float knitted on the inner peripheral surface of the mouth portion (see, for example, Patent Document 2). These elastic knitted fabrics have an anti-slip function by exposing an elastic yarn having a high friction coefficient to the surface of the knitted fabric and bringing it into contact with a contact object.

  The above-described elastic knitted fabric described in Patent Document 1 can be applied to warp knitting and weft knitting, and can expose elastic yarns for preventing slippage on both sides, but the elastic yarn spans between stitches. Since the length of the elastic yarn is short, the amount of elastic yarn bending in the direction perpendicular to the span is small, and momentary relative movement between the knitted fabric main body and the contact object due to movement or the like cannot be allowed much. For this reason, if the knitted fabric main body and the contact object are worn on a portion where there is a lot of instantaneous relative movement, the knitted fabric main body that has moved relatively does not return to its original position, and a stable anti-slip function cannot be exhibited. There is.

  On the other hand, the elastic knitted fabric described in Patent Document 2 is limited to circular knitted (weft knitted), and cannot be applied to a warp knitted elastic knitted fabric for bandages or supporters, and is perpendicular to the weft knitting. Anti-slip function can only be exhibited in the direction.

  Accordingly, an object of the present invention is to provide a warp knitted elastic knitted fabric that has a good touch and allows a momentary relative movement with a contact object due to exercise or the like and exhibits a stable anti-slip function. It is.

  In order to solve the above-mentioned problems, the present invention connects loop stitches made of warps in the weft direction, and knitted elastic yarns with the warp yarns or uses coated elastic yarns for the warp yarns. In the warp knitted elastic knitted fabric, a configuration was adopted in which the knitted stitches were floated in the warp direction and float elastic yarns were float knitted.

  That is, by floating the stitches in the warp direction and float knitting the float elastic yarn, the span of the float elastic yarn between the stitches is lengthened, and the amount of deflection in the direction perpendicular to the span of the float elastic yarn is increased. Allowing momentary relative movement with the contact object due to, etc., so that a stable anti-slip function can be exhibited. In addition, since the float elastic yarn bends over a long span and allows relative movement with the object to be contacted, this relative movement can be softly allowed, and it has a function to prevent slippage with the skin, such as bandages and supporters. Suitable for what is required.

  By shifting the float elastic yarn to the knitting stitches in the weft direction and performing float knitting, it is possible to exhibit a non-slip function in multiple directions.

  By setting the number of stitches to fly the float elastic yarn in the warp direction to 3 or more, the span of the float elastic yarn between the stitches is made sufficiently long, and the instantaneous relative movement with the contact object becomes larger. And can be softly tolerated.

  In the elastic knitted fabric of the present invention, since the float elastic yarn is float knitted by skipping the warp knitting stitches in the warp direction, the float elastic yarn span between the stitches is lengthened, and the float elastic yarn span and The amount of deflection in the right-angle direction can be increased, and an instantaneous relative movement with respect to the contact object due to movement or the like can be allowed to exhibit an anti-slip function. In addition, since the float elastic yarn bends over a long span and allows relative movement with the object to be contacted, this relative movement can be softly allowed, and it has a function to prevent slippage with the skin, such as bandages and supporters. Suitable for what is required.

  By shifting the float elastic yarn to the weft in the weft direction and making it a float knitting, it is possible to exhibit an anti-slip function in multiple directions.

  By setting the number of stitches to fly the float elastic yarn in the warp direction to 3 or more, the span of the float elastic yarn between the stitches is made sufficiently long, and the instantaneous relative movement with the contact object becomes larger. And can be softly tolerated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment. This elastic knitted fabric is a warp knitted elastic knitted fabric in which loop-shaped stitches 2 made of warp yarns 1 are connected by weft yarns 3 and elastic yarns 4 are knitted to warp yarns 1, and a plurality of float elastic yarns 5 are formed. The knitted portion 5a is shifted by one row in the weft direction with a span in which four stitches 2 are skipped in the warp direction, and is knitted and floated parallel to each other for each float. A polyurethane elastic yarn is used for the elastic yarn 4 and the float elastic yarn 5. Note that, for the warp 1 and the weft 3, any material is used regardless of whether it is elastic or inelastic.

  In the elastic knitted fabric, the float elastic yarn 5 that makes contact with the object to be contacted in a long span softly allows momentary relative movement with the object to be contacted by bending in a direction perpendicular to the span, and stable sliding in both the vertical and horizontal directions. Demonstrate the stopping function. Therefore, it is suitable for a product to be mounted on a part with a lot of movement such as a supporter or bandage for arms and legs.

  FIG. 2 shows a second embodiment. This elastic knitted fabric is also a warp knitted elastic knitted fabric similar to that of the first embodiment, and the number of warp stitches 2 between the knitted portions 5a of the float elastic yarns 5 is three, The difference is that the float elastic yarn 5 is folded back parallel to each other every three floats.

  FIG. 3 shows a third embodiment. This elastic knitted fabric is also a warp knitted elastic knitted fabric, and in the same way as in the second embodiment, each float elastic yarn 5 skips three stitches 2 in the warp direction and folds every three floats to float knitting. However, it differs from that of the second embodiment in that the adjacent float elastic yarns 5 are folded back in opposite directions.

  In each of the above-described embodiments, a warp knitted elastic knitted fabric in which an elastic yarn is knitted into a warp yarn is used, but a covered elastic yarn may be used as a warp yarn. Moreover, although the float elastic yarn is a polyurethane elastic yarn, any type and count elastic yarn can be used as the float elastic yarn. The thicker the float elastic yarn, the better the anti-slip function, but the thicker the yarn, the worse the touch.

  Further, the number of stitches in the warp direction of the float elastic yarn, the folding pattern in the weft direction for each float, and the number density with respect to the stitch row of the float elastic yarn are not limited to those of each embodiment, Can be designed arbitrarily. It should be noted that it is possible to eliminate the shift of the row of the float elastic yarn in the weft direction.
