Description

3D fabric and preparing method thereof

The present invention relates to a fabric capable of expressing three-dimensional solid shape and a method of manufacturing the same, which can be woven in one loom and one process, and is insulated with a three-dimensional solid fabric capable of changing the shape between the planar shape and the three-dimensional solid shape. The present invention relates to a fabric that can be applied for high efficiency blinds.

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.

Three-dimensional solid fabric 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 surface layer 100 and the back layer 200 are separated from each other as illustrated in FIGS. 2 to 7.

3D three-dimensional fabric according to the present invention is formed of a surface layer 100, the back layer 200, the intermediate layer 300 connecting the surface layer 100 and the back layer 200 as shown in FIG.

The surface layer 100 is formed of the surface contact portion 110 and the surface portion 120, and the back layer 200 is sequentially formed of the back contact portion 210 and the back surface portion 220.

The surface layer 100 is composed of the surface portion 120 and the surface contact portion 110 composed of the surface slope, the surface contact portion 110 is connected to the intermediate layer 300, the back layer 200 is composed of the back surface portion 220 and the rear surface contact portion 210 composed of the back slope. The back contact portion 210 is connected to the intermediate layer 300.

The surface portion 120 is woven only with surface inclination, the surface bonding portion 110 is woven with a first intermediate inclination to form a surface inclination and the intermediate layer 300, the back portion 220 is woven only with the back slope and the back connection portion 210 is the back slope and the intermediate layer 300 Weaved into a second intermediate slope to form a.

The intermediate layer is woven with only the first and second intermediate inclinations so that the first intermediate inclination forms the surface contact portion 110 and the second intermediate inclination forms the back connection portion 210 so as to be sequentially repeated on the surface connection portion 110 and the back connection portion 210. The first intermediate slope weaves the intermediate layer 300 and is connected to the back layer 200 with the first connecting slope 310 to form the back slope and the back contact portion 210, and the second intermediate slope weaves the intermediate layer 300 and the surface layer 100 After contacting to form the surface slope and the surface junction portion 110, the second connecting slope 330 is connected to the back layer 200, and then again the process of forming the first intermediate slope and the intermediate layer 300 is repeatedly performed to weave the fabric.

The fabric of the present invention woven as described above is connected to the surface layer 100 and the back layer 200 by the first and second connection inclination 310,330, so that the three-dimensional solid shape is not realized, and after weaving, the first and second connection inclination 310,330 Should be removed.

Since the first and second connection slopes 310 and 330 are removed, the three-dimensional three-dimensional shape can be expressed in a form in which the surface layer 100 and the back layer 200 are connected to each other by the intermediate layer 300.

The intermediate layer 300 is a layer which is connected to the surface bonding portion 110 and the back bonding portion 210 and connects the surface layer 100 and the back bonding layer 200. It would be desirable to weave to connect to the back joint.

Figure 3 is a simplification of the weaving method of the preferred embodiment according to the present invention by the inclination number, the surface inclination 1,2, the back slope 3,4, the first intermediate inclination 5,6, the second intermediate inclination number When the inclination is 7,8, the method of weaving the three-dimensional solid fabric of the present invention will be described below.

The surface portion 120 and the back surface portion 220 are woven with the inclination 1,2 and the inclination 3,4, respectively, and the intermediate layer 300 is woven from the back connection portion 210 with the surface connection portion 110 and woven with the inclination 5,6,7,8. Then, the slopes 5 and 6 are connected to the back surface layer 200 with the first connection slope 310 to form the back contact portion 210 together with the slopes 3 and 4, and the slopes 7,8 are in contact with the surface layer 100, and the slopes 1 and 2 together It forms the interview portion 110 and is connected to the back layer 200 with the second connecting slope 330 again to form the intermediate layer 300 with the inclination 5,6 and weaving the three-dimensional solid fabric.

That is, the surface portion 120 of the surface layer 100 is woven with inclination 1,2, and the surface contact portion 110 is inclined with 1,2,7,8, and the rear surface portion 220 of the back layer 200 is inclined 3,4, and the rear junction 210 is inclined 3 Woven with 4,5,6 and the intermediate layer 300 is woven with 5,6,7,8 to weave the fabric.

In the present invention, the first and second connection inclinations 310 and 330 must be removed to realize a three-dimensional shape. In order to more easily remove the first and second connection slopes 310 and 330, the first and second connection slopes 310 and 330 may be exposed on the back layer or the surface layer to form the first and second protrusions 410 and 430. As shown in the partially enlarged view of FIG. 2, the protrusion 500 forms a protrusion 500 to cover the first and second connection slopes 310 and 330 with two weft yarns from above and below to protrude to the surface of the back layer or the surface layer.

As shown in FIG. 4, first and second protrusions 410 and 430 are formed on the surface layer, and the first and second connection inclinations 310 and 330 protruding are fixed by the weft yarns as described above, and the weft yarns are continuous in the width direction. As a result, the first and second connection inclinations 310,330 (removing wefts) are exposed together. When removing by removing the weft yarn exposed on the surface, the first and second connecting slopes 310,330 intersecting with the weft yarns are also raised together to remove all of the first and second connecting slopes 310,330 together with the weft yarns. have.

Figure 5 shows the fabric in a state in which the first and second connecting slopes 310,330 are removed. Since the first and second connection slopes 310 and 330 are removed, the three-dimensional three-dimensional shape can be expressed in a form in which the surface layer 100 and the back layer 200 are connected to each other by the intermediate layer 300.

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.

The surface density of the fabric 100 or the back layer 200, or by using a weft or the like with a different tissue density of the fabric to put a pattern on the surface of the fabric will be able to enhance the interior effect and improve the aesthetics.

The heat treatment process may be performed to further improve the shape stability of the three-dimensional solid fabric according to the present invention described above or to reinforce stiff physical properties.

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 to 20% 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 surface layer, the back layer, the middle layer can be woven by varying the density of the tissue, respectively. For example, when the surface layer and the back layer are woven into a mesh structure and the intermediate layer is formed into a denser structure, the three-dimensional shape is not expressed in the fabric (as shown in FIG. 1). If the three-dimensional three-dimensional fabric according to the present invention exhibits a three-dimensional shape, the intermediate layer moves vertically with respect to the surface layer and the back layer, thereby exposing the inside and the outside of the fabric due to the mesh structure of the surface layer and the back layer. A structure that can be realized 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 spacing between the warp and the weft in the surface layer and the rear layer to 0.2 to 2mm can express a more desirable 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.

Furthermore, it would be desirable to flame retardant the three-dimensional solid fabric according to the invention to minimize the risk of fire.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
