Description

[Detailed description of the invention] [Industrial application field] The intermediate layer of the double-sided knitted fabric has a loop pile structure,
The present invention also relates to a three-layer knitted fabric in which the loop pile structure is arranged in a pattern.

[Conventional technology]

The pile structure knitted fabric in the conventional double-sided knitted fabric is a two-layer structure knitted fabric having a pile structure formed in a loop together with the front or back knitted surface. Recently, a three-layer knitted fabric with a loop pile structure has been proposed as an intermediate layer between front and back knitted fabrics in order to provide functions such as heat retention and bulkiness. In this case, a loop pile structure is formed together with the front and back knitted fabrics, and the knitted fabric has a relatively loose bonding structure by tuck binding or the like.

[Problem that the invention attempts to solve]

Therefore, in a two-layer knitted fabric, the loop pile yarn is formed in only one layer with the front or back knitted fabric, and the loop pile easily moves freely for each loop, causing unevenness in the knitted fabric. The surface is not uniform, the elasticity and cushioning properties change locally on the knitted surface, and it is difficult to incorporate air layers, so there are problems with heat retention.

In addition, even in a three-layer knitted fabric with a pile structure, the middle pile structure is formed integrally with the front or back knitted fabric, but the loop pile is formed with the front and back knitted fabrics by tack binding, etc. Since the loop pile is not fixed to the front or back knitted fabric, it tends to move freely and only serves as a link between the two outer layers of knitted fabric, and does not function as an intermediate layer.

Therefore, it is not possible to obtain a knitted fabric with a large fabric thickness, and in general, in order to stabilize the intermediate layer and increase the fabric thickness, thick yarn is used as the loop pile yarn in the intermediate layer, or the density of the loop pile part is increased. However, there are problems such as the resulting fabric having a heavy basis weight and being hard. Therefore, although three-layer knitted fabrics, which are currently widely proposed, are more effective than pile two-layer knitted fabrics in terms of functionality such as heat retention and bulkiness, they are not suitable for use in clothing, etc. It has problems with lightness, drapeability, etc., and although it has excellent functions, it is difficult to be used as a general-purpose product.

The purpose of this invention is to improve upon the shortcomings of the conventional technology, and to create a material that has functions such as heat retention and bulkiness, is lightweight and has excellent drapability, and can be used for general purposes such as clothing. Our objective is to provide a three-layer knitted fabric.

[Means for solving problems]

That is, in the present invention, a loop pile structure is formed in the intermediate layer of the double-sided knitted fabric together with the front knitted fabric or the back knitted fabric, and the loop base of the loop pile structure is formed in the loop of the front knitted fabric or the back knitted fabric. The three-layer knitted fabric is fixed, and is further characterized in that the loop pile structure is arranged in a pattern so that it has a portion where a loop pile is formed and a portion where it is not formed.

The loop pile structure of the intermediate layer of the knitted fabric of the present invention is fixed to the front or back knitted fabric by knitting with crimped yarns, etc., which is found in double-layer pile knitted fabrics. Therefore, compared to the conventional three-layer knitted fabric, the loop pile structure of the middle layer is stabilized, and the loop pile does not move or become loose, and sufficient bulkiness can be maintained. In addition, since the loop pile structure is arranged in a pattern, it has more space than conventional three-layer knitted fabrics, and has excellent heat retention and lightness. This makes it possible to create a three-layer knitted fabric that is soft and has excellent drapability.

Furthermore, by changing the pattern of the loop pile structure of the intermediate layer to an arbitrary size and shape, it is possible to arbitrarily change the formed loop pile structure arrangement part and the space part. You can freely select the functions, specifications, etc. of the fabric you want to use.

The present invention will be explained below based on the drawings.

Figure 1 is a layered bird's eye view showing the basic three-layer knitted fabric of this invention as a model.
The middle layer of the back knitted fabric has a loop pile structure arranged in a checkered pattern. Between the front knitted fabric 1 and the back knitted fabric 2,
It is composed of an intermediate layer 3 ¹ forming a loop pile structure and an intermediate layer 3 ² not forming a loop pile structure,
Further, the intermediate layer 3 forms a handle 4 by a combination of 3 ¹ and 3 ² . As mentioned above, the handle 4 is 3 ¹ , 3 ²
By changing the combination and shape of the fabrics, the desired fabric can be freely selected. Furthermore, by combining knitting structure changes on the front knitted surface and the back knitted surface, it is also possible to change the appearance due to changes in the front and back knitted surfaces.

Figure 2 is a cross-sectional view of the knitted fabric of the present invention.
The base of the loop pile part 5 integrally formed with the loop pile part 5 is completely fixed by the sewage thread 6 of the back stitch. Further, the apex 7 of the loop pile portion 5 on the opposite side is tack-bonded to the front knitted fabric 1, so that the bond is relatively loose. The tack bond forms an intermediate layer 3. Furthermore, the intermediate layer 3 has areas 3 1 where it is tuck-bonded to the front knitted fabric ¹ and areas 3 ² where it is not tuck-bonded.
It is composed of

Figure 3 A shows the knitting structure of the first yarn feeder, and Figure 3 B shows the knitting structure of the second yarn feeder. At the first yarn feeder, loop pile yarn c and sewage yarn d are knitted simultaneously on dial needle a. Then, in the cylinder needle b, the loop pile yarn is knitted in a pattern shape in a tacked state, and at the second yarn feeder, the loop pile yarn in the tacked state is knitted in a front stitch with the cylinder needle at the first yarn feeder. Obtainable.

The connection between the intermediate layer yarn and the front or back knitted fabric may be tuck or rib bonding, and the fixing point of the loop pile structure may be fixed on either the front or back side.
Alternatively, it may be fixed on both sides.

The fiber material used in the three-layer knitted fabric of the present invention is not particularly limited, but depending on the purpose, hydrophilic or hydrophobic yarns may be used in combination, yarns with antistatic performance, etc. may be selected and mixed. . Further, the size of the loop pile structure may be appropriately selected in consideration of the relationship with the threads constituting the outer material and the lining material and the intended use.

[Effect of action and idea]

In the three-layer knitted fabric of the present invention, the loop pile base is completely fixed by the loops of the front fabric or the lining fabric, so the loops will not shift or the outer fabric and lining will not peel off during use. Therefore, a fabric with excellent shape stability can be obtained.

Furthermore, the size of the loop pile structure can be changed freely, and the thickness of the fabric can be made from a conventional double-sided knitted fabric to 30 mm or more. Furthermore, since the loop pile structure is arranged in a pattern, the resulting fabric has excellent heat retention, lightness, and elasticity. In addition, since it is divided into two layers, the front knitted fabric and the back knitted fabric, through the loop pile structure, the entire knitted fabric moves like the loop pile structure, so even when subjected to a strong impact, the two layers can be The knitted fabric has excellent cushioning properties and strength, absorbing misalignment and protecting the inside.

〔Example〕

Hereinafter, the present invention will be specifically explained with reference to Examples.

Example 1 Using an 18 gauge double jersey machine, using polyester dyed yarn 150d/48f for the loop pile system,
Using polyester processed yarn SD75d/36f for the seam type,
Using 1/48 spun yarn for the front and back knitted fabrics, a 10 x 12 mm 2-diamond pattern was knitted into the loop pile part to create a three-layer knitted fabric with a thickness of approximately 3 mm, and finishing was performed. When a sweatshirt was made from the obtained knitted fabric and worn, it was found to be extremely soft, light, bulky, and had excellent heat retention.

Example 2 Using a 24 gauge double jersey machine, 42/1 cotton blend yarn was used as the sewage yarn, processed polyester yarn SD100d/72f was used as the loop pile yarn, and processed polyester yarn SD150d/48f was used as the front knitted fabric. I checked the loop pile pattern, created a three-layer knitted fabric, and dyed it. As a result of making a prototype of jogging wear using the obtained knitted fabric and wearing it, we found that sweat moves from the surface that comes into contact with the skin through the hydrophilic fibers to the loop pile structure layer.
Furthermore, since it was dispersed in a spatial layer, the surface that came into contact with the skin did not feel sticky and was comfortable.

In addition, by using the same 24 gauge and increasing the size of the loop pile structure layer, in addition to the above features, cushioning properties were increased, safety was added, and a fabric rich in comfort and safety was obtained.
