(Example 7)
A three-dimensional knitted product 1F according to Example 7 of the present invention will be described with reference to FIG.

The three-dimensional knitted product 1F according to the seventh embodiment is used for rugs and the like that require greater thickness and hardness than cushions. The three-dimensional knitted fabric 2F is composed of a front knitted fabric 10, a back knitted fabric 11, and a column portion 8, and is made of a hard synthetic leather material that covers the edge region of the three-dimensional knitted fabric 2F.

Further, almost the entire lowermost part of the lining 15 is provided with the same non-slip processing portion 14 (dotted) as described above. ) is added.

With such a configuration, as in Example 1, both end regions of the column portion 8 made of fibers having a higher rigidity than usual protrude toward the inner side of the folded and joined sewn region, and the column portion can be seen from the cut surface of the three-dimensional knitted product 1G. It is possible to provide a hemless three-dimensional knitted product 1G which is highly safe and has a non-slip function because the fibers of the part 8 which are more rigid than usual protrude so as not to directly irritate the skin.

In addition, it is more preferable to sew the portion of the folded and joined sewn area in three windings.

FIG. 12 shows, for example, a three-dimensional knitted product 21 with a rug specification using the three-dimensional knitted product 1 according to Example 1, and FIG. It is a schematic perspective view showing each of three-dimensional knitted products 22 as specifications.

Currently, products with mattress specifications generally use rubber tape-like stretchable materials at the four corners to prevent slippage by hooking them on the mattress, but the bottom of the mattress product has been treated to prevent slippage. By adding it, the difficulty of hooking work can be improved by the variety of thickness and weight of this mattress.

When three-dimensional knitted fabrics are used for rugs, etc., thickness and hardness are required, and reinforcement of normal cushioning properties is required, but this strengthens the rigidity of the fibers of the pillars, which causes more irritation to the skin of the protrusions. becomes even more problematic.

At this time, a protruding object may penetrate the ordinary edge cover material, so it is more desirable to use hard synthetic leather or the like with air permeability of 0.

For this reason, it is stitched as a picture frame type edge cover to prevent protrusion. In addition, the frame portion of the surface portion is preferably about 3 to 10 cm or more in consideration of design.

Next, a further description of the present invention will be added.

By folding and sewing the three-dimensional knitted product, the thickness of the three-dimensional knitted product wraps around the protruding object and contributes to avoiding irritation to the skin.

In addition, if the three-dimensional knitted fabric is a one-piece specification, the back part of the whole, or if other fabric is used as the lining, the entire lining can be treated with PVC or silicone resin to have a non-slip effect. A sufficient anti-slip effect can be obtained during use of the entire product. Even if the folding part is processed to prevent slipping, the product still has the anti-slip effect.

Furthermore, when the three-dimensional knitted product is a multi-layered product, the three-dimensional knitted product or general fabric that is folded into the bottom layer back side of the bottom layer or the bottom layer side of the outer peripheral part is processed with PVC or silicone resin to have a non-slip effect. If you use it, you can exhibit the anti-slip effect of the entire product.

In addition, when using a rug-like specification as mentioned above, the entire back surface of the three-dimensional knitted fabric is treated with PVC or silicone resin to prevent slippage, or when using felt fabric or other materials as the lining. If you use a non-slip fabric, you can get a non-slip effect for the entire product.

Furthermore, even if a three-dimensional knitted fabric or other fabric treated with anti-slip such as PVC or silicone resin is used for the partial material of the back side edge, a sufficient anti-slip effect is exhibited.

INDUSTRIAL APPLICABILITY The present invention can be suitably used in fields such as cushions, floor pads, floor products such as rugs, sofa covers, and pet products.
