JPH04272283A - Chenille woven fabric and method for forming double-side raised pattern in chenille weaving - Google Patents

Abstract

PURPOSE:To obtain a double-side raised pattern rich in designability by weaving chenille yarn, having a pattern and composed of heat shrinkable yarn and unshrinkable yarn of different colors as weft yarn and thermally shrinking the resultant chenille woven fabric. CONSTITUTION:Heat shrinkable yarn and unshrinkable yarn of different colors are subjected to mixed weaving to weave a plain weave fabric. The raw fabric of the plain weave is cut along warp yarn thereof to provide slender pieces, which are then twisted to prepare chenille yarn having a stripe pattern. Chenille yarn shrinkable by heating and chenille yarn without shrinking by heating are used as weft yarn, placed in a prescribed arrangement and woven to afford a chenille woven fabric, which is subsequently heat-treated to provide a chenille woven fabric of double-side raised pattern formed by unevennesses without distinction between the front and back surfaces.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to clothing, accessories, bedding,
It relates to woven fabrics used to decorate personal items.

0002

BACKGROUND OF THE INVENTION Conventionally, there has been no fabric with a raised pattern on both sides, but only one with a raised pattern on one side. For this one-sided fabric, a raised pattern was formed by changing the height of the pile to create unevenness, or a raised pattern was formed by applying unevenness using a pressing means.

[0003] Furthermore, there is a chenille fabric that has the same pattern on both sides. This chenille fabric is woven using chenille yarn, which is a special twisted yarn, as the weft.

[0004] To explain this in detail, first, a plain weave raw cloth is woven so that weft threads of a predetermined color different from the warp threads are woven into predetermined positions of the warp threads, and this plain weave raw cloth is cut into thin strips parallel to the warp threads. When this strip-like piece is twisted around the warp, a striped chenille yarn is obtained in which the weft of each color protrudes in a pile around the warp. Then, when a plain weave structure is woven using this chenille yarn as a weft so that a predetermined colored portion is present at a predetermined position, a chenille weave, which is a pile-like woven fabric with a desired pattern, is obtained.

[0005]

[Problems to be Solved by the Invention] However, with the above-mentioned conventional one-sided raised pattern, it was not possible to form a complex and highly decorative pattern, and only a relatively simple raised pattern could be formed. In addition, it was not possible to create a floating pattern on the fabric with no distinction between the front and back sides, and the back side had no decoration.

[0006] The chenille weave has the same pattern on both sides, but there has never been one with a raised pattern where the pattern part stands out from the base pattern.

The object of the present invention is to eliminate the above-mentioned drawbacks and provide a woven fabric with a complicated floating pattern, regardless of whether it is on the front or the back.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention involves interweaving threads of different colors to form a plain weave raw fabric, and cutting the plain weave raw fabric along the warp of the plain weave raw fabric. In the chenille weaving, in which the striped strips are twisted to obtain a chenille yarn with a striped pattern, and the chenille yarns are woven in a predetermined arrangement as wefts, the yarns of different colors are used as heat-shrinkable yarns and non-heat-shrinkable yarns. Then, the woven chenille fabric was further heat-treated to shrink the heat-shrinkable yarn to form floating patterns on both sides of the fabric.

Furthermore, yarns of different colors are mixed and woven to form a plain weave raw fabric, and the plain weave raw fabric is cut along the warp threads to give a twist to the strips, thereby producing a chenille yarn having a striped pattern. In a chenille weave in which the chenille yarns were woven in a predetermined arrangement as wefts, the yarns with different colors were used as yarns with different bulks.

0010

[Operation] The chenille weave, which is the basis of the present invention, weaves a plain weave structure by arranging mall-shaped multicolored chenille threads in a predetermined manner, so that the fabric has the same pattern on both sides without distinguishing between the front and back, making it possible to form complex patterns. . When forming this pattern, the fabric is made by mixing threads that shrink with heat and threads that do not shrink, and when heat is applied, the heat-shrinkable threads shrink while the other parts remain as they are, creating unevenness and creating a floating pattern. becomes. Also, if you weave yarns with different bulk from the beginning, it will create unevenness and a floating pattern. In order to create a shrinkable part and a non-shrinkable part using threads of the same material, it is best to apply shape memory processing to the part you want to shrink and then heat-treat it to shrink it.

[0011]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] In the first embodiment of the present invention, first, a method for producing a decorative chenille fabric will be explained, and for the convenience of explanation, a second color (for example, blue) background pattern is coated with a second color.
A case of a simple two-color pattern in which a star-shaped pattern 1 of a color (for example, green) is formed will be described.

FIG. 1 is an original pattern diagram for weaving a decorative chenille fabric, and the background pattern area 2 is a vertical line in the y-axis direction corresponding to the warp and a chenille yarn woven into the warp. It is divided into unit areas by horizontal lines in the x-axis direction. A star-shaped pattern 1 is drawn as a line diagram on the background pattern area 2 divided into unit areas in this way, and a second color of green is colored in the portion of this star-shaped pattern 1, and the star-shaped pattern is Background pattern areas 2 other than 1 are colored blue, which is the first color. In reality, an original pattern in which many such patterns are drawn is used, but in the following explanation, for convenience, one pattern unit will be discussed.

[0014] The original pattern map in which a pattern of desired shape and color is formed is read by a computer for each unit area. This reading is performed in the unit area Ao of row A in FIG.
Starting from , scanning reading is performed in the positive direction of the x-axis, moving from unit area Am to unit area Bm of row B, and scanning reading of row B is performed in the negative direction of the x-axis. Similarly below,
The entire unit area is scanned and read in a zigzag pattern such as row C, row D, row E, and so on.

By this scanning and reading, the address of each unit area and the corresponding color are stored in the storage device of the computer. Plain weaving corresponding to the original pattern is performed by a dobby loom that is controlled and driven by reading out the color corresponding to the address of each unit area of the original pattern from the storage device of the computer.

FIG. 2 shows the plain woven fabric thus obtained, and portions A to E correspond to rows A to E in FIG. 1, respectively. First, section A in FIG. 2 is a plain weave area corresponding to row A in FIG. 1, and the color of all unit areas in row A is blue, which is the first color. A thread 4 in which three blue weft threads each made of a heat-shrinkable yarn such as an acrylic high bulky yarn or a blend of high bulky yarns are twisted together is woven into a white warp yarn 3 made of double yarns. The warp yarns are closely warped several at a predetermined cutting interval, and in the following sections B to E, the first color blue background pattern section is 1
Three blue weft threads 4 twisted together are woven into the white warp threads 3 of No. 00 twin threads, and a plurality of warp threads are closely warped at predetermined intervals.

In the area B in FIG. 2, a band 5 is formed in the second color green at the center position in the weaving direction. In this case, in the band-shaped portion 5, three green wefts of No. 10 are twisted together with each of the white warps 3 of No. 100 twin threads 5 are woven. In parts C to E, three green wefts of No. 10 are twisted together at predetermined positions with respect to the white warp of No. 100 double thread, forming band-like parts 6 to 8. be done.

In this way, a plurality of plain weave raw fabrics each having strips 5 to 8 of the second color woven and formed at predetermined positions of the warp in the weaving direction are closely warped in the middle of the warp 3. The chenille yarn 9 as shown in FIG. 3 is obtained by cutting into thin strips at the positions and twisting each of the cut strips. This chenille yarn 9 has a structure in which weft yarns of first and second colors (blue and green in the example) are arranged symmetrically and protrudingly as piles around the warp yarns in a step-dyed pattern.

The chenille yarn created through the above steps is used as a weft and woven into the warp of No. 100 twin yarns to obtain a chenille woven fabric.

When heat is applied to this chenille fabric, the blue weft 4 shrinks due to the heat and is recessed from the green weft 5 to 8 portions (see FIG. 4). By doing this, a decorative fabric with raised patterns on both sides is obtained.

[0021] In the first embodiment, different types of threads were interwoven, but in the second embodiment, even the same yarns, such as cotton and wool, can be made into a floating pattern on both sides. In place of the blue weft 4, shape-memory-treated blue cotton yarn or wool is used, and when it is woven into a chenille woven fabric and then heat-treated, the shape-memory-treated portion shrinks, so it is the same as the first embodiment. Here, shape memory processing is
As described in Japanese Patent Application Laid-open No. 2-62989 and Japanese Patent Application Laid-open No. 62-62990, a collagen protein derivative or a hebroin protein solution or a mixed solution of a keratin protein solution and a collagen protein derivative are adsorbed onto cotton thread or wool. Bye.

Furthermore, instead of utilizing shrinkage due to heat, if the bulk of the blue weft 4 and the green wefts 5 to 8 are mixed and woven as different yarns, such as filament and spun yarn, to create a chenille weave, the bulk will be different. becomes uneven and has a raised pattern on both sides.

[0023]

[Effects of the Invention] As described above, the present invention utilizes chenille weave to create irregularities by using shrinkage due to heat and differences in bulk, and can also be made into a raised pattern on both sides, resulting in a complex and decorative design. The effect is that a fabric having rich double-sided floating patterns can be easily mass-produced and provided at low cost.
