Description

The present invention uses a monofilament thread with thick and hard monofilaments on a surface fabric in which multi-colored geometric patterns or picture patterns are expressed by multilayer weaving with high-density warp and weft yarns. A high-density multi-layered woven fabric with no pattern, which is formed by crossing the warp of the front fabric and the weft of the back fabric, and integrating them with the direct bonding technique. Thick plain fabrics and products using them.

  In conventional thick-patterned fabrics, thick fabric is formed by using thick yarn for warp and weft, or by stitching another fabric or sheet to the patterned fabric, or by bonding with an adhesive. Form.

  When using thick yarn for warp and weft in a conventional thick fabric, the density (number) of warp and weft is reduced for organizational reasons. Therefore, it is not possible to express fine pattern patterns precisely with various colors. Also, in terms of functionality, there are problems such as inferior elasticity, original shape recovery, tension, and strength, and occurrence of defects such as expansion, contraction, bending, twisting, and wrinkles in any of the vertical and horizontal directions.

  In addition, a method in which another fabric or sheet is applied to an ordinary pattern fabric and sewed or bonded with an adhesive is also used. However, these problems cannot be solved all over.

  The present invention seeks to solve these problems without following the conventional weaving method and bonding method. In addition, the thick patterned fabric and the thick plain fabric are used as surface materials. It is intended for use in small items such as tatami mats, tatami mats, beds, chairs, furniture, indoor wall coverings, and bags and boxes.

  In order to achieve the above object, a technique is used in which the warp yarn of the front fabric is crossed with the weft yarn of the back fabric and is directly connected while weaving the front fabric and the back fabric simultaneously.

  On the surface of the outer fabric, the geometrical pattern or the pattern must be beautifully expressed. “Beautiful” means a variety of colors, a fine and precise pattern, and a change in the texture of the pattern. Therefore, in order to make these possible, use the highest possible number of yarns for both the warp and the weft, and further use one or more types of pre-dyed yarn for the warp and four or more types of pre-dyed yarn for the weft. It is preferable to use it.

  Further, in order to balance the thickness of the back fabric, the front fabric itself needs a certain thickness. For this purpose, it is desirable to use a multi-layer weave structure when expressing the pattern.

The back fabric complements the thickness that is insufficient for the front fabric, and satisfies various functions required as a material. Therefore, thick and hard monofilament yarns are used for the warp and weft, and the weaving method is a mesh-like plain weave.

  As for the number of beams for raising the warp of this fabric, a plurality of beams are required for the front fabric and one for the back fabric. This is because the front fabric has a multi-layered weave structure, so that a difference in the degree of weaving shrinkage occurs between the warp yarns, and the back fabric uses yarns completely different from the front fabric.

  Since the present invention is configured as described above, the following effects can be obtained.

  In the surface fabric of this woven fabric, the number of warps and wefts used is as high as possible, the types of color yarns used for these warps and wefts are multicolored, and the woven structure is a multi-layer weave With these specifications, it is possible to express a fine, detailed and colorful pattern.

  In the back fabric of this woven fabric, the thickness of the entire thick woven fabric can be freely adjusted by making the monofilament yarn used as warp and weft finer or thicker.

  A thick-patterned fabric woven from such a front fabric and back fabric using a direct bonding technique does not stretch or contract even when pulled diagonally in the vertical and horizontal directions, and is elastic even when pressed and has an original recoverability. Further, for example, even when used for a tatami mat, there are no defects such as wrinkles, twists, breaks, twists, collapses, and tears.

  When the back fabric is directly connected to the front fabric composed of 4 layers, it becomes a 5-layer structure, so that it has air permeability, flexibility, sound absorption and heat retention.

  Since the traditional tatami mat is a woven stalk of a plant weed with hemp thread, the epidermis of the stalk is peeled off by friction and the contents are exposed. The new blue tatami mat will turn yellowish brown over time. The dent made in the pressed part with heavy furniture cannot be repaired. However, this thick fabric is resistant to friction and does not discolor, and the dent due to the pressure is restored to its original shape with time.

  Since the cocoon grass used in conventional tatami mats is a plant, it produces mold and body, but with this fabric, those concerns are unnecessary.

  In recent tatami mats, there is a tatami mat-like product using synthetic resin called chemical tatami mat. This chemical tatami mat is cold, breathable, supple, sound-absorbing and heat-retaining, especially when it is used, thin fluff is generated, which gradually becomes thicker and longer, giving skin discomfort, clothes To damage. There are problems such as stickiness when wet, but there are no concerns about the thick fabric.

  Conventionally, when tailoring a tatami mat, a tatami mat is used together as determined. However, this thick woven fabric is supple, strong, and has a good tension and restoration, so that the use of tatami edges can be omitted. The room with tatami mats without tatami edges looks wide and does not trip.

  In addition, if the tatami rim is omitted, this thick fabric can be attached to the tatami floor using a commercially available gun tucker or the like without the help of a craftsman in each household, so it will be rearranged at a low cost. be able to. In addition, because there is no fading, even if only some tatami mats are rearranged, the old and new feeling of incongruity does not appear.

  This thick fabric is tougher and longer lasting than the tatami mats, and is environmentally friendly.

  As described above, the effect of the thick woven fabric described using the tatami mat as an example also applies as it is when used as a surface material such as a bed, a chair, furniture, a bag, a box, or an interior material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings.
FIG. 1 is a woven structure diagram of a solid F (abbreviated to ground or ground) portion corresponding to a portion having no color pattern on the surface of the surface fabric 9 of FIG. In this embodiment, the movement of the warp 1 is based on a structure of 8 satin and the weft 2 is woven, and the order of colors is yellow, red, green, and blue. Yellow and green are located in the upper layer 3, and red and blue are located in the lower layer 4. The eight satin warps 1 are composed of yellow and green dots 5 on the upper layer 3. The red and blue of the lower layer 4 are organized as warps 1 with as few points 6 as possible. Also, red and blue hardly appear on the plain surface, and yellow and green should appear on the surface only at the texture point of 8 sheets, but the density of the warp 1 is high. In addition, it does not appear on the surface between the warp and the warp. Therefore, the color of the ground is expressed only by the color F of the warp 1. (FIG. 1 (a)) shows that the warp 1 of the front fabric 9 intersects the weft (yellow and green) of the upper layer 3, the point 6 of intersecting the weft (red and blue) of the lower layer 4, and the back This represents a texture point 16 that intersects the weft 8 of the fabric 10. (FIG. 1 (b)) shows a situation in which eight warp yarns 1 are crossed with a weft yarn 2 of the front fabric 9 and a weft yarn 8 of the back fabric 10, respectively. By comparing this figure with (FIG. 1A), the relationship between the texture of the front fabric and the texture of the back fabric can be explained in more detail.

  FIG. 2 is a woven structure diagram of the colored pattern on the surface of the front fabric 9. In the embodiment, the colors used for the pattern are five colors of yellow (A), red (B), green (C), blue (D), and red-blue (E). The pattern of yellow A is expressed by arranging the wefts of yellow A on the plain warp 1 composed of eight satin pieces in accordance with the contour of the pattern. The pattern of red B, green C, and blue D is also expressed in the same manner as yellow A. The red-blue E is expressed as a mixed color of red and blue by alternately arranging red-blue-red-blue.

  In FIG. 2, beige F is a plain color in which only the beige warp 1 appears on the surface due to the structure of eight satin. Under this layer, there are an upper layer 3 of yellow, green, and a lower layer 4 of red, blue, so that the plain is formed of three layers. The red / blue E has three layers because the layer of the warp 1 is located between the upper layer 3 and the lower layer 4. In yellow A, red B, green C, and blue D, there are four layers because the pattern color yarn is positioned above the warp yarn 1 layer.

  In FIG. 3, one square row arranged in the vertical direction means one warp 1 of the front fabric 9, and one square row arranged in the horizontal direction represents the weft 2 of the front fabric 9. It means one by one. Further, in the cross-sectional view 11 of the warp and the cross-sectional view 12 of the weft, the arrangement of the warp 1 and the weft 2 of the front fabric 9 is shown.

  The warp 13 and the weft 14 of the back fabric 10 are positioned below the warp 1 of the front fabric and the weft 2 of the front fabric shown in the cross-sectional view 11 of the warp and the cross-sectional view 12 of the weft. is doing. In addition, it is shown that the warp of the back fabric intersects the weft of the back fabric, the weft of the back fabric intersects the warp of the back fabric, and the back fabric 10 is independent of the front fabric 9 It reveals that it is a mesh structure.

Since it is necessary for the backing fabric 10 to have a sufficient thickness and functions such as elasticity, strength, and stiffness, the warp yarn 13 and the weft yarn 14 are both thick monofilament yarns.

  Therefore, the ratio between the number of warps of the front fabric 9 and the number of warps of the back fabric 10 is set to 3: 1. Accordingly, the arrangement position of each warp yarn of the back fabric is directly under the warp yarn corresponding to a multiple of 3 in the arrangement sequence of the warp yarns of the front fabric. Similarly, since the ratio of the number of weft yarns is 4: 1, the arrangement position of the weft yarns on the back fabric is the order of the weft yarns on the front fabric, that is, directly below the blue weft yarns of yellow, red, green and blue.

  In FIG. 3, a cross symbol 15 is a texture point where the back fabric warp 13 and the back fabric weft 14 intersect, and a circle symbol 16 indicates that the front fabric warp 1 intersects the back fabric weft 14, It is a tissue point that directly connects the back fabric to the front fabric.

  The same partial diagram 17 described in the upper margin of FIG. 3 is obtained by taking out a part of the lower diagram and rewriting it for easy viewing.

  FIG. 4 is a contour diagram showing a multicolor pattern in the embodiment. There are six types of coloring: yellow (A), red (B), green (C), blue (D), mixed red and blue (E), and beige (F). Display the color.

  In the examples, the density of the number of warps is 69 per cm for the front fabric, 23 per cm for the back fabric, and 92 total for the front and back. The density of the number of wefts is 56 per cm for the front fabric, 14 per cm for the back fabric, and 70 in total for the front and back.

  In the embodiment, the thickness of the yarn used for the warp of the front fabric is 225 dtex, and the thickness of the yarn used for the weft of the front fabric is 15th of the cotton number. The thickness of the yarn used for the warp and weft of the back fabric is 245 dtex.

  In the examples, the warp and weft materials of the front and back fabrics are all non-chlorine synthetic fibers.

  Since the warp and weft yarns using the above-mentioned thickness are formed with the highest possible density, the effect of the water-repellent processing by post-processing can obtain Grade 5.
