Three-dimensional three-dimensional fabric having a three-layer structure and its manufacturing method {Three-layer 3D Fabric and Preparing}

The present invention relates to a woven fabric having a three-dimensional solid shape having a three-layer structure and a method of manufacturing the same, which can be woven in one loom and one process, and can be changed in three-dimensional shape between a planar shape and a three-dimensional solid shape. The fabric constituting the middle of the three-dimensional fabric is a multi-layer structure relates to a fabric that can be applied for blinds with high light blocking rate and high thermal insulation efficiency.

Fabrics are made from certain raw materials and are formed by weaving, knitting, plaiting or braiding and are also felt by interlocking fibers. The fabric is made.

Basic standard types of fabrics can be divided into fabrics, knits, felts, plates, nonwovens, adhesives, and molds. A narrow woven fabric is a fabric in which the warp yarn in the vertical direction and the weft yarn in the horizontal direction cross each other at right angles. The most common use for under wear and outer wear is textiles, which are mostly used. On the other hand, the knitted fabric (knitted) is made of a single loop of the yarn (loop) and these rings are combined in the front and rear and left and right directions to form a knitting. Knitted fabrics are chopped quickly and are limp and elastic when worn. In addition, the felt (felt) is made by interlocking the fibers of the first stage by heat, moisture, pressure, and striking to form a felt, the yarn is not used here. Also, plaited, braided, and lace have several yarns running in one direction, and one yarn crosses to produce the desired effect. Nonwovens are fabrics in which webs or sheets of fibers adhere to each other by the application of an adhesive material, or by adhesion fibers through surface chemistry, or heat of thermoplastic fibers. Laminated fabric also forms a fabric by adhering a foam to one or two fabrics. It is generally soft and fluffy to the touch and effective. Finally, the mold fabric has a larger mold area than that of the circular plane from which it was extracted. Molded articles (clothes) are fluffy or in the form of piles or flat. The product is comfortable to wear and fits well with the body's functions and does not change shape.

Since fabrics exist in a two-dimensional perspective, they do not utilize or use their sides. Therefore, three-dimensional solid shape is realized by sewing or other joining methods.

US Patent No. 3,384,519 in the industrial part applying this, proposed to use a double fabric to form a double and then to form a movable blade in the center to bond the fabric and the blade by bonding or bonding. The method moves the blade horizontally and light enters through the mesh fabric, and when the blade moves vertically, it blocks the light and finally adjusts the amount of light. Although there is an advantage in controlling the blade and the fabric may be a source of indoor environmental pollution because of the adhesive to the adhesive or adhesive, and furthermore, in the long-term use, there is a problem in that the bonding state is degraded or separated due to the degradation of the adhesive by ultraviolet light.

First, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

The term "fabric" is used herein to mean all of the convened textiles, knits, felts, plates, nonwovens, adhesives, and mold fabrics. However, in describing an embodiment of the present invention, a narrow woven fabric is described as an example. Therefore, in describing the weaving method of the fabric according to the present invention, it is natural that both the warp and the weft cross are woven, and the expression 'only the warp is woven' in the present specification means that the warp and the weft cross. However, this is not the case when there is an expression that does not specifically intersect the weft.

Three-dimensional three-dimensional fabric having a three-layer structure according to the present invention can be formed in a three-layer structure. Although actually woven as shown in FIG. 1, for convenience of understanding, the back layer 100, the first connection layer 200, the intermediate layer 300, the second connection layer 400 and the surface layer 500 will be described as shown in FIGS. 2 to 4.

The conceptual view of the surface of the fabric according to the example, Figure 6 is a three-dimensional appearance of the fabric according to the preferred embodiments of the present invention, Figure 7 is a state diagram used in accordance with a preferred embodiment of the present invention.

2 to 4, the first connection layer 200 connecting the back layer 100, the intermediate layer 300, the surface layer 500 and the back layer 100 and the intermediate layer 300, and the second connection layer connecting the intermediate layer 300 and the surface layer 500 as shown in FIGS. It is formed to 400.

The first connection layer 200 and the second connection layer 400 may be woven so as to be symmetrical with each other based on the intermediate layer 300.

The present invention is a three-dimensional three-dimensional fabric having a three-layer structure of the present invention in the form of a fabric comprising a section A including the first connection layer 200 and the second connection layer 400 shown in Figure 2 repeatedly After forming the back layer 100 and the first connection layer 200, the slopes forming the first group slope and the surface layer 500 which is connected to the back layer 100 to form a first connection slope 610 and the back layer 100 again After forming the second connection layer 400, the intermediate layer 300, the second group inclined through the process of connecting to the surface layer 500 to form a second connection inclination 630 and to form a surface layer again, the first group and the second group The inclination proceeds repeatedly each.

In addition, the first group inclination starts at the back layer 100 and the first connection layer 200, respectively, and weaves sequentially, and the second group inclination starts at the middle layer 300, the second connection layer 400, and the surface layer 500, respectively. Weave sequentially to weave the fabric.

The inclination between the first and second groups should be bonded to each other by connecting the first connection layer 200 and the second connection layer 400 to each other to have a three-layer structure. The connection between the two groups may be such that the first connection layer 200 and the second connection layer 400 are formed to be in contact with each other in the intermediate layer, and the intermediate layer 300 may be inclined to form the first connection layer 200 and the second connection layer 400 and the intermediate layer 300. It will be desirable to form a three-dimensional three-dimensional fabric having a three-layer structure by joining the inclination between the two groups to form an intermediate junction 310 to contact.

The intermediate junction 310 is to increase the density of the fabric than other parts to increase the morphological stability of the three-dimensional three-dimensional fabric having a woven three-layer structure fabric of the present invention is a junction portion of the back layer 100 and the surface layer 500 Not formed. Therefore, as shown in the drawing, the density of the fabric may be denser on the back layer 100 or the surface layer 500, or the back joint 110 or the surface joint 510 may be formed using a thick weft to increase the shape stability of the fabric. .

As described above, the two-piece fabrics inclined form a three-dimensional shape by cutting the first and second inclined yarns after weaving.

Figure 3 is a simplification of the weaving method of the preferred embodiment according to the present invention by the inclination number, the first group inclination starting from the back layer 1,2,3,4, the first group inclination starting from the first connecting layer 5,6, the second group slope starting from the middle layer 7,8, the second group slope starting from the second connecting layer 9,10, the second group slope starting from the surface layer 11,12,13,14 If we explain the weaving method of section A, it is as follows.

The slopes 1,2,3,4 form the back layer 100 by a predetermined length, and then form the first connection layer 200, form the first connection slope 610, and contact the slopes 5,6 connected to the back layer 100. The ground slopes 3 and 4 form the first connection layer 200 and the remaining slopes 1,2, 5 and 6 form the back layer 100.

The inclinations 5 and 6 are in contact with the inclination 7,8 forming the first connection layer 200 and the intermediate layer 300 and the inclination 9 and 10 forming the second connection layer 400 and woven together to form the intermediate junction 310. , Slopes 5 and 6 form the first connection slope 610, slopes 8 and 8 form the second connection slope 630, and slopes 9 and 10 form the intermediate layer 300.

The slopes 11, 12, 13, and 14 form the surface layer 500, and then form the second connection slope 630, and when in contact with the slope 9, 10 connected to the surface layer 500, the slopes 13 and 14 form the second connection layer 400. The remaining inclinations 7,8,11,12 form the surface layer 500.

In the weaving method, the inclination number is also different in sections B and C, and the inclination of the same position produces a three-dimensional three-dimensional fabric having a three-layer structure according to the present invention.

That is, the first group slope forms the back layer 100 of two sections, forms the first connection layer 200, and then contacts the back layer 100 again with the first connection slope 610 to form the back layer 100 in three cycles. Repeating, the second group inclination forms the surface layer 500 of two sections, the second connection layer 400, the intermediate layer 300, and then the four periods of contacting the surface layer 500 again with the second connection slope to form the surface layer 500. Repeat weaving the fabric.

The fabric of the present invention woven as described above is connected to the back layer 100 and the surface layer 500 by the first and second connecting slopes 610 and 630, so that the three-dimensional solid shape is not realized. Should be cut (removed).

In order to more easily remove the first and second connection slopes 610 and 630 formed as described above, the first and second connection slopes 610 and 630 may be exposed on the surfaces of the back layer 100 and the surface layer 500 to form the back protrusions 710 and the surface protrusions 730. Can be. The back surface and the surface protrusions 710 and 730 surround the first and second connection slopes 610 and 630 with two weft yarns from above and below, as shown in the partially enlarged view of FIG. 2, and form the surface protrusions 710 and 730 to protrude on the surface of the back layer 100 and the surface layer 500. Let's do it.

As described above, the first and second connection slopes 610 and 630 exposed to the back layer 100 and the surface layer 500 are fixed by weft yarns, and as shown in FIG. 5, the weft yarns continuously extend in the width direction. It is exposed with a connecting warp 610,630 (removing weft). When the exposed weft for removal is lifted and removed, the first and second connection slopes 610 and 630 intersecting with the weft yarn are also raised together, and cutting occurs at each connection part, so that the first and second connection slopes together with the weft yarn are removed. Both 610 and 630 can be removed.

4 shows the fabric in a state in which the first and second connection slopes 610 and 630 are removed. As the first and second connection slopes 610 and 630 are removed, the back layer 100, the intermediate layer 300, and the surface layer 500 are three-dimensional three-dimensional shapes having a three-layer structure connected to each other by the first connection layer 200 and the second connection layer 400. This becomes possible.

6 and 7 is a view showing a state of use of the fabric according to an embodiment of the present invention shows a case in which the three-dimensional shape is expressed on the fabric by raising the surface layer.

When using a three-dimensional three-dimensional fabric having a three-layer structure according to the present invention as a blind, the back layer 100 is fixed and the height of the middle layer 300 and the surface layer 500 can be adjusted to control the shading rate, and also the middle layer is fixed and the back layer The light blocking rate may be adjusted by adjusting the heights of 100 and the surface layer 500.

The heat treatment process may be performed to further improve the shape stability of the three-dimensional three-dimensional fabric having a three-layer structure according to the present invention described above or to reinforce stiff physical properties. Preferably, the stiff physical properties can be imparted to the fabric as a heat treatment before performing the cutting step. This is because when the cutting step is performed before the heat treatment, the fabric is damaged because radical action such as cutting is applied to the fabric while the multilayer fabric is in close contact with the fabric.

To this end, we can weave using a low melting point yarn to the warp and / or weft. The low melting point yarn intentionally lowered the melting point by a method selected from one or more of a method consisting of modifying the molecular structure, copolymerization, blending, spinning process control, complex spinning, the surface is subjected to heat treatment within a temperature range of about 120 to 190 degrees Celsius Any yarn having a property that can be finely fused can be used. Specifically, a copolyester-based binder fiber prepared by copolymerizing terephthalic acid or its ester-forming derivative and ethylene glycol and neopentyl glycol proposed in Korean Patent Invention No. 2,9414 may be used. In addition, the LM (Low Melting) manufactured by the compound spinning, the LM is a part that the core (core) to the local area and the seed (sheath) is fused during heat treatment, the low melting point component proposed in Korean Patent Invention No. 587122 And a high melting point component, wherein the low melting point component continuously forms at least a part of the fiber surface in the fiber direction, and has a glass transition temperature of 60 ° C. or higher and 50 to 70 mol% of a polyethylene terephthalate unit. It is also possible to use a heat sealable composite fiber composed of a mixture of ˜99% by weight and 20-1% by weight of polyolefin.

On the other hand, warp and / or weft yarns may be used by mixing low melting point yarns and flame retardant yarns, or composite fibers (sheath-core type, split type, multi-sea island type, etc.) formed of low melting point parts and flame retardant parts, or mixed yarns of low melting point yarns and flame retardant yarns. Can be. In this case, it may be used as an industrial material, particularly for curtains or blinds. In this case, the ratio of the low melting point portion and the flame retardant portion or the low melting point yarn and the flame retardant yarn is preferably about 15:85 to 50: 50% by weight. If the flame retardant part (sa) is included below the ratio, the flame retardant effect is lowered, and if it is included in the above range, the low melting point (sa) is poorly fused at the time of heat treatment. .

Fabrics according to the present invention, the back layer, the intermediate layer, the surface layer, the first connection layer, the second connection layer may be woven by varying the density of the tissue, respectively. For example, when the back layer, the middle layer, and the surface layer are woven in a mesh structure and the first and second connection layers are formed in a denser structure, when the three-dimensional shape is not expressed in the fabric, the inside and the outside of the fabric are exposed to each other. When the three-dimensional three-dimensional fabric having a three-layer structure according to the present invention, or a three-dimensional structure, according to the present invention expresses a three-dimensional shape, the first and second connection layers move vertically with respect to the back layer, the middle layer, and the surface layer. Due to the mesh structure of the intermediate layer and the surface layer, a structure in which the inside and the outside of the fabric can be exposed to each other is realized.

This means that it can be utilized as a shading or security material, and can express new functions as a clothing material. To this end, when the interval between the warp and the weft in the back layer, the middle layer, the surface layer is 0.2 to 2mm can achieve a more preferable effect. In addition, the fabric according to the present invention can be woven by changing the structure or design of the surface layer, the back layer, the intermediate layer, the first connection layer, the second connection layer.

Furthermore, it would be desirable to minimize the risk of fire by flame retardant treatment of the three-dimensional three-dimensional fabric having a three-layer structure according to the present invention.
