Description

Elastic reinforced three-dimensional fabric and car seat made of the three-dimensional fabric TECHNICAL FIELD

The present invention relates to a fabric, and more particularly, to an elastically reinforced three-dimensional fabric excellent in elasticity and excellent in elastic recovery, and a car seat made of the three-dimensional fabric.

In general, to alleviate the impact caused by movement or load of the human body, furniture such as mattresses and sofa chairs, beddings such as mats and pillows, or guards used to protect the injured part in case of injury such as fractures of the human body. Cushion materials are used in the interior, and such cushion materials are mainly used as sponges made by foaming synthetic resins, latexes made by foaming natural rubber, and cotton balls made of fibers.

Among the known cushioning materials, latex is widely used for furniture such as bed mattresses because of its excellent breathability, elasticity and durability, but the production of natural rubber latex, which is the main raw material, is not only difficult to mass-produce, but also natural rubber, which is the main raw material. Since the latex is very expensive, the selling price of the product is very expensive, and the air permeability is poor due to the too dense cell structure, so when used for bedding, there is a problem of poor comfort.

Plush is used for bedding because it is easy to mass-produce like sponges and it is inexpensive and has the most natural cushioning and excellent breathability.However, there is a problem that the restoring force is remarkably deteriorated due to the loss of cushioning and thickness during long-term use. In the case of the three-dimensional fabric-type cushioning material in which the connecting yarn is connected between the fabric plates, the fabric is composed of only the weaving of the connecting yarn with the inclination of the fabric plate composed of the double layer. There are many limitations to the scope of use due to the problem.

In particular, since the sponge foams synthetic resins, it is easy to control the physical properties, so that the product can be produced by freely modifying the density, hardness, and repulsive cushioning feeling, which can be used for a wide variety of applications, and has a cell structure by foaming. Because of its excellent breathability, easy mass production, and low cost, it is manufactured using synthetic resins and chemicals. When manufactured to a thickness there was a problem such as easy tearing during use.

On the other hand, as an alternative to the conventional cushioning material in recent years, the fabric plate consisting of the warp and weft yarn consists of a top plate and a bottom plate, and the connection between the top plate and the bottom plate using a connecting thread so that the two plates to maintain a constant gap, elasticity and breathability A three-dimensional fabric cushioning material has been developed to be used, and is used in various fields such as furniture and bedding. Patent application No. 10-2008-0030485 describes the three-dimensional fabric cushioning material “slope (A1, B1) and weft (A2). Weaving B2 connects the slopes A1 and B1 constituting the upper plate A and the lower plate B so that the space C is formed at regular intervals between the upper plate A and the lower plate B formed by weaving B2. In the three-dimensional fabric type cushioning material which is woven by zigzag and woven in the yarn (3), a plurality of fixed yarns (4) in the transverse direction to the connecting yarn (3) joined between the upper plate (A) and the lower plate (B) Three-dimensional structure of weaving Fabric cushion material ”is disclosed.

The three-dimensional fabric-type cushioning material disclosed in the patent is to reduce the elasticity of the use time through the dense structure of the structure obtained by further tightening the connection structure of the connecting yarn bonded between the fabric formed in a multi-layer structure through the weaving and post-processing process Although intended to prevent, due to the fastening structure, the surface of the top plate or the bottom plate is lifted and crushed from the time of manufacture or use, and the elastic recovery is reduced as the distance between the top plate and the bottom plate gets closer despite the fastening structure. The problem still exists without being solved.

However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Like reference numerals designate like elements throughout the specification.

1 is a perspective view of an elastically reinforced three-dimensional fabric of the present invention.

As shown in Figure 1, when looking at the structure of the elastic reinforcing three-dimensional fabric of the present invention, the elastic reinforcing three-dimensional fabric 100 is the first inclination of the first weave and the first weaving yarn 110 and the second inclination and second inclination It can be seen that the weft-shaped double weave structure 120 is provided while forming a constant space between the weave bottom plate 130 is woven.

Here, the X-shaped double weave structure 120 is zigzag weaving the first slope 111 constituting the upper plate 110 and the second slope 131 constituting the lower plate 130 in a zigzag using a connecting yarn 121 ( The first weft yarn 112 of 110 and the second weft yarn 132 of the bottom plate 130 are connected to the connecting yarn 121 in a horizontal direction, in particular using a plurality of connecting yarn 121 repeatedly at regular intervals. It is obtained by forming a structure in which the connecting yarn 121 is connected to each other by crossing, and weaving a plurality of fixed yarns 122 in the transverse direction, respectively, in the upper and lower portions of the cross-connected connecting yarn 121.

Since the X-shaped double weave structure 120 configured as described above maintains a gap between the upper plate 110 and the lower plate 130, an external load is applied from the outside of the upper plate 110 or the lower plate 130 toward the X-shaped double weave structure 120. When applied, the gap between the upper plate 110 and the lower plate 130 is narrowed by the elasticity of the X-shaped double weave structure 120, and the shock due to the external load is absorbed, as well as the outside of the upper plate 110 or the lower plate 130. When the external load applied from the extinction, the upper plate 110 and the lower plate 130 by the elasticity of the X-shaped double weave structure 120 is to be carried out as a cushioning material because the restoration is made at the original interval is to be able to perform the function. .

In the present invention, the first inclination 111 of the upper plate 110 and the second inclination 131 of the lower plate 130 are made of a material having excellent elastic recovery in order to strengthen the elastic recovery of the three-dimensional fabric of such a structure. The use of a processed yarn has its technical characteristics. Here, the first weft yarn 112 of the upper plate 110 and the second weft yarn 132 of the lower plate 130 may use ordinary yarns as they are, and may use a stretched processed yarn, but to reduce manufacturing costs General history can be used.

At this time, it is preferable that the processing yarn made of a material excellent in elastic recovery is a processing yarn containing spandex or mono TPE YARN (thermoplastic elastomer).

In more detail, the processing yarn containing spandex is a mixed processing (covering, interior, ATY, joint, etc.) by mixing the spandex and other hetero yarns.

Mono TPE is a processing yarn made of thermoplastic elastomers, in particular styrene type such as thermoplastic styrenic block copolymer (SBC), Olefin type such as thermoplastic olefinic elastomer (TPO), urethane type such as thermoplastic polyurethane (TPU), and thermoplastic polyamide (TPAE) amide It is a processed yarn made of any one of a polyester-based or polyester-based, such as TPEE (thermoplastic polyester elastomer).

As described above, when the first yarn 111 of the upper plate 110 and the second yarn 131 of the lower plate 130 are made of a material having excellent elastic recovery, the upper plate forming a conventional three-dimensional fabric and Since the surface of the lower plate is lifted and crushed is eliminated, the elastic reinforcing three-dimensional fabric 100 of the present invention is that the upper plate 110 and the lower plate 130 will not appear at all during the manufacturing and / or the use of the flickering phenomenon In addition, it contributes to maintain the elasticity of the three-dimensional fabric 100 even if the weight is repeatedly applied.

On the other hand, in order to not only ensure excellent breathability, but also to provide increased elasticity and resilience, in the elasticity-reinforced three-dimensional fabric 100 of the present invention as a connecting yarn 121 to form an X-shaped double weave structure 120 in general Low temperature, including low temperature fusion PET, which has excellent elasticity recovery and softness and elasticity than PET, and melts at 120 ~ 210 ° C as a fixed yarn 122, and melts at 120 ~ 210 ° C than general PET that melts at about 250 ° C. It is preferable to use fusion yarn

In particular, when the X-shaped double weave structure 120 has a structure of a denser connecting yarn 121, the elasticity and resilience by the connecting yarn 121 can be further increased, and the fixed yarn 122 is connected to the connecting yarn 121. When fusion is fixed to the X-shaped double weave structure 120 gives shape stability, between the upper plate 110 and the lower plate 130 by maximizing the fixing force and the supporting force of the connecting yarn 121 by the fixed yarn 122 The gap between the connected yarn 121 may be prevented from being disturbed or the organization of the tissue may be damaged to maintain uniform elasticity and resiliency at any point of the upper plate 110 and the lower plate 130.

Two warp beams are used to weave the elastically reinforced three-dimensional fabric configured as described above, and the first inclination and the second inclination and the first weft and the second weft and the second weft and the connecting yarn and the fixed yarn are different in color, or By varying the spacing it can be produced elastically reinforced three-dimensional fabric 100 of the present invention having a desired design.

When the elastic reinforcing three-dimensional fabric 100 is cut as it is to be sewn in the desired design can be easily manufactured car seat even without attaching a separate cushioning material, such as a laminate foam.

Elastic reinforcing three-dimensional fabric of the present invention and the car seat made of the three-dimensional fabric not only eliminated the fluffing and crushing phenomenon due to the lack of elongation of the inclination constituting the upper and lower plates had a conventional three-dimensional fabric, but also the elastic recovery of the three-dimensional fabric itself The improved elasticity is further enhanced, making it easy to manufacture cushioned textile products including car seats.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various changes and modifications will be possible.
