Description

  The present invention relates to a patchwork fabric formed by combining a plurality of cloth pieces for use in patchwork for sewing a plurality of cloth pieces having different patterns and colors into one large cloth.

  Currently, patchwork or patchwork quilt making is booming in the handicraft field. Originally, the patchwork quilt originated in 1620 when British Puritans went to the United States on the Mayflower for freedom. They made patchwork quilts by stitching pieces of worn clothes together, making bedding and wall hangings to prevent crosswinds. At that time, patchwork was done to enlarge the cloth, and there was nothing that was well-designed, but the tradition of this patchwork quilt was still present after the western pioneering period in America.

  The patchwork quilt is now re-evaluated by the collection “Abstract Design in America” published by Jonathan Holstein in 1971. As a result of this announcement, patchwork quilts began to be evaluated again, and not only old things but also new designs of patchwork quilts were created using new methods. Patchwork quilting is once again revived as a way to comfort the hearts of modern people.

  Current patchwork or patchwork quilt making belongs to the field of hobbies. Consumers who make patchwork quilts purchase multiple fabrics with patterns and colors that suit their tastes, and do not cut them into small pieces of cloth, instead of using vintage clothing or scraps. The work is combined to create a free-form patchwork quilt.

  By the way, when a consumer who makes a patchwork quilt purchases a fabric, the fabric must be purchased in units of 1 m or 50 cm in length with a full width of about 1 m. In addition, there is a problem in that it is necessary to purchase as many fabrics as the number of pieces to be combined in patchwork. Furthermore, there has been a problem that when a small piece of cloth to be used is cut from the purchased cloth, most of it remains. In addition, even if we have fabrics with patterns and colors that match our image, the types of the fabrics are not uniform, and the thickness and woven structure of each piece of cloth is different. There was a problem that the sense of unity could not be expressed.

  On the other hand, in response to the demands of these consumers, handicraft stores sell a set of a combination of a plurality of fabrics of a predetermined width and full width, with patterns and colors changing with similar types of fabrics. . However, even in this case, there is a limit to unifying the types of fabrics, and there remains a problem that if a small piece of cloth to be used is cut from a set of purchased fabrics, many of them remain.

  In addition, it is conceivable that the handicraft shop changes the pattern and color of the fabrics to be combined with patchwork, cuts them into small pieces of cloth, and combines them for sale as a piece of cloth. However, in this case, it is difficult to unify the types of fabrics, and there is a problem that the labor for creating the cloth piece set is large, and the selling price of the cloth piece set becomes high and it is difficult for consumers to purchase. .

  In view of the above, the present invention addresses the above-described problems, and a plurality of pieces of cloth to be combined by patchwork are arranged in one kind of one piece of cloth, and the patterns and colors of these pieces of cloth are respectively different. An object of the present invention is to provide a fabric for patchwork that can obtain a set of fabric pieces necessary for patchwork by simply cutting a plurality of pieces of fabric, and that is less wasteful such as cut residue in the fabric. And

  In solving the above-mentioned problems, the present inventors, as a result of diligent research, effectively printed one piece of fabric and combined the plurality of pieces of cloth necessary for patchwork into a minimum area, thereby performing the above-described printing. The inventors have found that the problems can be solved and have completed the present invention.

That is, the fabric for patchwork according to the present invention is as described in claim 1.
One piece of fabric formed by printing a geometric pattern in which a plurality of sections composed of one or more polygons are regularly combined,
The geometric pattern is formed by stacking the sections in a plurality of stages in the longitudinal direction and the width direction of the fabric,
Most of the compartments are composed of different patterns or different colors,
The different patterns or different colors are printed by ink jet means.

According to the description of claim 2, the present invention provides the patchwork fabric according to claim 1,
In some of the plurality of sections, the entire geometric pattern formed by combining the plurality of sections is printed as a reduced pattern.

According to the description of claim 3, the present invention provides the patchwork fabric according to claim 1 or 2,
The section is composed of one or more polygons selected from the group of regular triangles, isosceles triangles, squares, rectangles, rhombuses, trapezoids, and regular hexagons.

According to the description of claim 4, the present invention provides the patchwork fabric according to any one of claims 1 to 3,
A seam allowance and a cutting line are provided along each boundary of the section.

Further, according to the fifth aspect of the present invention, in the fabric for patchwork according to any one of the first to fourth aspects,
The fabric is a cotton fabric, and the pattern or color is printed with a reactive dye.

  According to the said structure, the fabric for patchwork which concerns on this invention consists of one piece of fabric. This one piece of fabric is printed with a geometric pattern, and this geometric pattern is formed by regularly combining a plurality of sections made of one or more kinds of polygons. Each section of the geometric pattern corresponds to each piece of cloth to be combined with patchwork. In the present invention, by cutting and dividing these sections, it is possible to easily obtain a cloth piece set composed of a plurality of cloth pieces having a size to be combined with patchwork.

  Thus, a consumer who makes a patchwork quilt has no inconvenience of purchasing a plurality of fabrics necessary for the patchwork in the full width by the unit length. Further, the consumer only needs to purchase one piece of the fabric for patchwork according to the present invention, and does not need to purchase as many fabrics as the number of pieces to be combined in the patchwork.

  In addition, the cut piece set is cut from one piece of cloth, the types of the woven fabrics are unified, and the thickness and woven structure of each piece of cloth are the same. This makes it easy to sew together and express a sense of unity when combining these fabric piece sets with patchwork. Furthermore, there is little cut residue and the consumer does not need to do extra shopping.

  Moreover, according to the said structure, most of each division is comprised by the different pattern or a different color. Therefore, the consumer can cut each piece of cloth from one piece of cloth, and can freely arrange this piece set according to his / her own image. Thus, a consumer can easily perform a patchwork with a variety of changes by purchasing only one patchwork fabric according to the present invention.

  Moreover, according to the said structure, these different patterns or different colors are printed by the inkjet means. Printing by ink jet means is adopted in the present invention as being suitable for printing a free pattern or color on each part of the fabric. Therefore, producers of patchwork fabrics can print one type of fabric without printing different types of printing patterns on separate fabrics, greatly reducing the labor of preparing a set of fabric pieces. it can.

  Moreover, the pattern and color of each section printed on one piece of fabric can be freely combined. Therefore, the producer can express a series pattern having a unified image in one piece of fabric in accordance with consumer preference and fashion. This also broadens the range of choices for consumers, and can lead to the discovery and popularity of new consumers in the field of patchwork quilts.

  Moreover, according to the said structure, it prints as a pattern where the whole geometric pattern which combined several divisions into some divisions, for example, one division among several divisions which comprise a geometric pattern, was reduced. You may do it. Therefore, a consumer who wants to purchase a fabric for patchwork can grasp the entire image just by looking at the section of the reduced pattern. As a result, even when the patchwork fabric is folded when sold at a handicraft store, the patchwork fabric is expanded to expand the entire patchwork fabric even if the reduced pattern section appears on the surface. Consumers can purchase without checking colors and colors.

  Furthermore, according to the said structure, each division which comprises a geometric pattern is 1 type, or 2 or more types of polygons chosen from the group of a regular triangle, an isosceles triangle, a square, a rectangle, a rhombus, a trapezoid, and a regular hexagon. You may make it consist of. These polygons are shapes generally used for patchwork, the lengths of the respective sides are the same, and it is easy to sew together with the patchwork.

  Moreover, according to the said structure, you may make it provide a seam allowance and a cutting line in each boundary of each division which comprises a geometric pattern. This is convenient when the consumer cuts and stitches the patchwork fabric.

  Moreover, according to the said structure, the fabric for patchwork may be a cotton fabric. At this time, the pattern or color of each section may be printed with a reactive dye. Cotton is a natural material and is popular with consumers as a material that can be used in patchwork.

  Therefore, in the present invention, a plurality of cloth pieces of a size to be combined by patchwork are arranged in one kind of cloth, and the patterns and colors of the plurality of cloth pieces are respectively changed. The cloth piece set required for patchwork can be obtained simply by cutting the patchwork, and a patchwork fabric with less waste such as a cut residue can be provided.

It is the schematic which shows Example 1 of the fabric for patchwork which concerns on this embodiment. It is the schematic which shows Example 2 of the fabric for patchwork which concerns on this embodiment. It is the schematic which shows Example 3 of the fabric for patchwork which concerns on this embodiment. It is the schematic which shows Example 4 of the fabric for patchwork which concerns on this embodiment.

  In this embodiment, first, the shape and size of a piece of cloth used for patchwork is determined. Since the cloth pieces are sewn together by patchwork, most of the cloth pieces are preferably polygons of the same shape having sides of the same length. In addition, these polygons are preferably symmetrical with respect to the left and right, and more preferably, for example, equilateral triangles, isosceles triangles, squares, rectangles, rhombuses, trapezoids, and regular hexagons.

  In the present embodiment, the geometric pattern is configured by regularly combining polygons employed as the shape of the cloth pieces. That is, this geometric pattern is formed by stacking a plurality of polygons in the longitudinal direction and the width direction of the fabric. When the polygon is a square having the same shape, this geometric pattern is a lattice pattern. When the polygon is a regular hexagon, the geometric pattern is a honeycomb pattern. At this time, squares, rectangles, diamonds, regular hexagons, and the like are regularly arranged in the same direction. On the other hand, equilateral triangles, isosceles triangles, trapezoids, and the like are arranged in a state of being rotated 180 ° in the left-right or up-down direction. In this way, the filling is regularly arranged without gaps.

  Further, the size of the cloth piece needs to be within the entire width of the cloth used by the entire geometric pattern arranged as described above. Therefore, it is preferable to combine the shape and size of the employed polygon so that they are within the full width of the fabric to be used, and the fabric is not wasted. In this way, the number of pieces of cloth necessary for patchwork are efficiently arranged on one piece of cloth.

  Further, a seam allowance and a cutting line may be provided along the boundary of each polygon arranged efficiently on one piece of fabric. By providing a cutting line in the patchwork fabric, when the consumer cuts the fabric into each piece of cloth, the site to be cut can be easily determined. On the other hand, by providing a seam allowance for the patchwork fabric, when the pieces of cloth cut by the consumer are sewn together, the portion can be easily determined.

  As described above, the seam allowance and cutting line provided in the patchwork fabric are particularly effective when the adjacent polygonal pattern and color are complicated and the boundary is not clear. Further, it is not necessary to provide both the seam allowance and the cutting line together, and only the seam allowance, only the cutting line, or both the seam allowance and the cutting line may be provided. Note that if the color of the adjacent polygon pattern is quite different and the boundary is clear, there is no need to provide a cutting line.

  Next, the pattern and color in the adopted polygon are determined. That is, each pattern and color are determined for a plurality of polygons constituting a geometric pattern that fits on one piece of fabric. In addition, about this pattern and color, all the polygons may be plain or all the polygons may have a pattern. Furthermore, among all the polygons, some may be plain and others may have a pattern.

  When adopting plain, it is preferable that each polygon has a different color. Moreover, when employ | adopting a pattern, each polygon may have the same pattern or may each have a different pattern. Furthermore, even when the same pattern is employed, it is preferable to employ patterns having different color schemes.

  In addition, a plurality of polygonal patterns and colors constituting a geometric pattern that fits on one piece of fabric may be created with a unified theme as a background. For example, if a uniform theme such as seasons such as spring, summer, autumn and winter, mountains, seas, animals and plants, scenery of various places, or abstract patterns is provided, consumers will be interested.

  Here, for a plurality of polygons constituting a geometric pattern that fits on one piece of fabric, a part of the polygons, for example, a geometric pattern that fits on one piece of fabric (pattern and color) May be reduced. This is due to the following reason. For example, when the patchwork fabric according to the present embodiment is sold at a handicraft store or the like, the fabric is folded and packaged from the manufacturing stage to the distribution and sales. In this case, the surface of the folded package is made into a transparent package so that the entire pattern and the color-reduced portion can be confirmed at a glance. This allows a consumer who wants to make a patchwork quilt to easily grasp the overall pattern and color without unpacking and spreading the patchwork fabric being sold.

  Next, the geometric pattern consisting of a plurality of polygons determined so far, the pattern and color of each polygon, and, if necessary, the seam allowance and cutting line are put together into a fabric by an inkjet printing machine. Print.

  Here, any fabric may be used for the patchwork fabric according to the present embodiment. Usually, a woven fabric is often used for making a patchwork or a patchwork quilt, but a nonwoven fabric such as a knitted fabric or a felt may be used instead.

  Moreover, the fiber which comprises these fabrics is not specifically limited, Generally, it may be used as clothing and industrial materials. For example, synthetic fibers such as polyester, nylon and acrylic, semi-synthetic fibers such as acetate, natural cellulosic fibers such as cotton and hemp, regenerated cellulosic fibers such as rayon, cupra, polynosic or tencel, protein fibers such as wool and silk and so on. These fibers may be used singly or as a mixture of two or more kinds of fibers such as mixed spinning, mixed fiber, union knitting, union knitting, etc. at an arbitrary ratio.

  Moreover, the inkjet printing machine used for this embodiment should just use what is normally used for the digital printing of a woven / knitted fabric, and is not specifically limited. These inkjet printing machines include a traveling inkjet printing machine that prints from a small inkjet head that moves in the width direction with respect to a fabric that runs in the long direction, and a cloth that runs in the long direction. Fixed inkjet printing machines that print from large inkjet heads fixed in width are used. In addition, there are a continuous type and an on-demand type as the ejection method of the ink jet printing machine, and there are a piezo method and a thermal method as the on-demand type.

  Further, the ink used in the ink jet textile printing machine may be appropriately selected depending on the type of fiber constituting the fabric to be printed. Therefore, disperse dye ink is used for polyester fibers, acid dye ink is used for nylon, wool and silk, and reactive dye ink is used for cotton and rayon fibers. On the other hand, the pigment ink can be used for any of the fibers even when two or more kinds of fibers are mixed in an arbitrary ratio.

  Here, the reason why the inkjet printing machine is employed in the present invention will be described. Conventionally, roller printing machines, rotary screen printing machines, flat screen printing machines, and the like have been used for general textile printing. Each of these printing machines has a characteristic in the pattern area to be expressed, and in normal fabric printing, different types are used depending on the type of pattern to be expressed.

  Therefore, in order to print a plurality of patterns having changes such as patchwork cloth pieces, it is necessary to perform printing separately for each pattern using a printing machine suitable for each pattern. For example, for fine line patterns, roller printing machines are suitable, flat screen printing machines are inferior, and rotary screen printing machines are inappropriate. On the other hand, for a pattern having a large area, a flat screen printing machine or a rotary screen printing machine is suitable.

  In addition, all of these printing machines must prepare a plurality of printing dies corresponding to the number of colors for each pattern. These printing dies require a manufacturing cost corresponding to the number of sheets to be used, and the manufacturing cost of the printing dies cannot be absorbed unless a large amount of printing fabric is produced using the same printing dies. In addition, if the color scheme changes even with the same pattern, it is necessary to perform printing separately for each color scheme.

  In the printing of patchwork cloth pieces, it is necessary to perform printing corresponding to a plurality of patterns and a plurality of colors. For this purpose, it is necessary to prepare a plurality of printing dies for each pattern and perform printing separately for each pattern and each color scheme. As a result, in the printing of patchwork cloth pieces with a small amount of use in each pattern and color scheme, not only a very large number of printing dies are required, but also the production costs of the printing dies are performed separately. The cost of the printing work increases.

  Furthermore, in each of the above-mentioned printing machines, there is a limit to the repeat length of the pattern called mold feeding. Therefore, the pattern of the patchwork cloth piece is limited by the repeat length, and it is difficult to manufacture a patchwork cloth piece having a free size. As described above, when each conventional printing machine is used, it is difficult to individually cope with patchwork cloth pieces whose patterns and colors, or polygonal shapes and sizes change.

  Therefore, in the present invention, by using an ink-jet printing machine, it is possible to correspond to different patterns and colors or different shapes and sizes of polygons without considering the pattern area and repeat length, and Since a printing mold is not required, it is possible to perform printing of a necessary amount on the same fabric at the same time. Therefore, in the present invention, an ink jet printing machine is used.

  Hereinafter, the fabric for patchwork according to the present embodiment will be described with reference to each example. In each example, a patchwork or a cotton fabric that is popular for making patchwork quilts is used, and reaction is performed using an on-demand type piezo-type traveling inkjet printing machine (resolution: 600 dpi for background). Printed with dye ink.

(Preparation of fabric)
In Example 1, a plain fabric (fabric width 115 cm) using 100% cotton and 50th single yarn was used. The cotton fabric used was pre-treated for inkjet printing after being desizing, scouring, bleaching, and mercerizing by a conventional method. The pretreatment for inkjet printing on this cotton fabric was carried out by a usual method. That is, an anti-bleeding agent for preventing bleeding of the ejected ink, an alkali agent necessary for coloring of the reactive dye, and other printing aids were uniformly applied to the cotton fabric in advance and dried.

(Preparation of printed pattern)
In Example 1, a polygon having a side of 20 cm was adopted as a polygon constituting the geometric pattern, and a geometric pattern composed of a total of 25 squares of 5 rows and 5 columns was formed. FIG. 1 is a schematic view showing a patchwork fabric 10 according to the first embodiment (the pattern only shows an image). In FIG. 1, the longitudinal direction of the fabric is the vertical direction shown in the figure. For a fabric width of 115 cm, a lattice pattern 11 of 5 rows by 100 cm and 5 rows by 100 cm is formed.

  For the 25 squares 12, different patterns from the existing textile pattern database and different colors were used. In the first embodiment, the seam allowance and the cutting line are not adopted. In Example 1, the lattice pattern and each pattern and color were converted into digital data by an image processing system built in the microcomputer and commanded to the ink jet textile printing machine.

(Printing and coloring)
The lattice pattern and each pattern and color were printed with a reactive dye on the traveling cotton fabric according to a command from the microcomputer. The printed cotton fabric was dried, the reactive dye was fixed with a steamer color machine, washed and dried to obtain a patchwork fabric of Example 1 composed of a plurality of squares.

(Preparation of fabric)
In Example 2, a twill fabric (cloth width 115 cm) using 100% cotton and 40th single yarn was used. The cotton fabric used was pre-treated for inkjet printing after being desizing, scouring, bleaching, and mercerizing by a conventional method. The pretreatment for inkjet printing on the cotton fabric was performed in the same manner as in Example 1 above.

(Preparation of printed pattern)
In the second embodiment, an isosceles triangle having a base of 20 cm and a height of 20 cm is adopted as a polygon constituting the geometric pattern, and a geometry composed of a total of 50 isosceles triangles of 5 rows and 10 columns. Made up the school. FIG. 2 is a schematic view (pattern is omitted) showing the patchwork fabric 20 of the second embodiment. In FIG. 2, the longitudinal direction of the fabric is the vertical direction in the figure. For a fabric width of 115 cm, a geometric pattern 21 of 5 rows by 100 cm and 10 rows by 110 cm is formed. The isosceles triangles 22 are filled and arranged while alternately rotating by 180 °.

  Further, for the 50 isosceles triangles 22, different patterns from the existing textile pattern database were used, and the colors were also different. In the second embodiment, the seam allowance and the cutting line are not adopted. In Example 2, the geometric pattern and each pattern and color were converted into digital data by an image processing system built in the microcomputer and commanded to the ink jet textile printing machine.

(Printing and coloring)
The geometric pattern and each pattern and color were printed with a reactive dye on the traveling cotton fabric according to a command from the microcomputer. After the printing, drying, fixing, washing and drying were performed in the same manner as in Example 1 to obtain a patchwork fabric of Example 2 composed of a plurality of isosceles triangles.

(Preparation of fabric)
In this Example 3, the same cotton fabric as in Example 1 was used. The pretreatment for inkjet printing on the cotton fabric was performed in the same manner as in Example 1 above.

(Preparation of printed pattern)
In the third embodiment, a rhombus having a length of 35 cm and a width of 24 cm is adopted as a polygon constituting the geometric pattern. A geometric pattern consisting of individual diamonds was constructed. FIG. 3 is a schematic diagram (pattern is omitted) showing the patchwork fabric 30 of the third embodiment. In FIG. 3, the longitudinal direction of the fabric is the vertical direction shown in the figure. A geometric pattern 31 having a length of 120 cm and a width of 10 rows and a height of 110 cm is formed for a fabric width of 115 cm.

  Further, the 18 rhombuses 32 employ different patterns from the existing textile pattern database and have different colors. In Example 2, a seam allowance 33 and a cutting line 34 were adopted, and the seam allowance 33 was not printed as a white field, and the cutting line 34 was simultaneously printed as a broken line printed pattern. In Example 2, the geometric pattern, each pattern, color, and cutting line were converted into digital data by an image processing system built in the microcomputer and commanded to the inkjet printing machine.

(Printing and coloring)
In accordance with a command from a microcomputer, the above-mentioned geometric pattern, each pattern and color, and a cutting line were printed with a reactive dye on a running cotton fabric. Drying, fixing, washing, and drying after printing were performed in the same manner as in Example 1 to obtain a patchwork fabric of Example 3 composed of a plurality of rhombuses.

(Preparation of fabric)
In this Example 4, the same cotton fabric as in Example 1 was used. The pretreatment for inkjet printing on the cotton fabric was performed in the same manner as in Example 1 above.

(Preparation of printed pattern)
FIG. 4 is a schematic view showing the patchwork fabric 40 according to the fourth embodiment (the pattern only shows an image). In the fourth embodiment, as the polygons constituting the geometric pattern, a square 42 having a side of 20 cm as in the first embodiment is adopted, and the same 5 rows and 5 columns as in the first embodiment. A lattice pattern 41 composed of a total of 25 squares was formed. In addition, the 25 squares 42 employ the same pattern and color as in the first embodiment. In Example 4, the seam allowance and the cutting line are not adopted.

  In Example 4, different patterns are formed in one square located in the upper left corner of the 25 squares (see FIG. 4). That is, a single square located at the upper left corner is printed as a reduced pattern of the entire lattice pattern composed of 25 squares. In Example 4, the lattice pattern, each pattern and color, and the reduced pattern were converted into digital data by an image processing system built in the microcomputer and commanded to the ink jet printing machine.

(Printing and coloring)
The lattice pattern, each pattern and color, and the reduced pattern were printed with a reactive dye on the traveling cotton fabric according to a command from the microcomputer. Drying, fixing, washing and drying after printing were performed in the same manner as in Example 1 to obtain a patchwork fabric of Example 4 composed of a plurality of rhombuses. In the patchwork fabric of Example 4, as described above, the entire lattice pattern composed of 25 squares is printed as a reduced pattern on one square located in the upper left corner. ing.

  From the above, the fabric for patchwork according to Examples 1 to 4 is composed of a single cotton fabric, and each geometric pattern is printed on this single cotton fabric. Each of these geometric patterns is a regular combination of a plurality of polygons each formed of a square, an isosceles triangle or a rhombus. By cutting and dividing the polygons of these geometric patterns, it is possible to easily obtain a cloth piece set including a plurality of cloth pieces having a size to be combined by patchwork.

  Thus, a consumer who makes a patchwork quilt has no inconvenience of purchasing a plurality of fabrics necessary for the patchwork in the full width by the unit length. Further, the consumer only needs to purchase one piece of patchwork fabric as in Examples 1 to 4, and does not need to purchase as many fabrics as the number of pieces to be combined in the patchwork.

  In addition, the cut cloth set is cut from one cotton fabric, the types of the fabric are unified, and the thickness and woven structure of each fabric piece are the same. This makes it easy to sew together and express a sense of unity when combining these fabric piece sets with patchwork. Furthermore, as seen in the above Examples 1 to 4 (see FIGS. 1 to 4), there is almost no cut residue, and the consumer does not need to do extra shopping.

  Moreover, according to the said Examples 1-4, each polygon is comprised by the respectively different pattern or a different color. Therefore, the consumer can cut each piece of cloth from one piece of cloth, and can freely arrange this piece set according to his / her own image. Thus, a consumer can easily perform patchwork with a variety of changes by purchasing only one piece of patchwork fabric as in Examples 1 to 4 above.

  Also, these different patterns or different colors are created by inkjet printing. Therefore, producers of patchwork fabrics can print one type of fabric without printing different types of printing patterns on separate fabrics, greatly reducing the labor of preparing a set of fabric pieces. it can.

  Moreover, the pattern and color of each section printed on one piece of fabric can be freely combined. Therefore, the producer can express a series pattern having a unified image in one piece of fabric in accordance with consumer preference and fashion. This also broadens the range of choices for consumers, and can lead to the discovery and popularity of new consumers in the field of patchwork quilts.

  Moreover, according to the said Example 3, the seam allowance and the cutting line are provided in each boundary of each rhombus which comprises a geometric pattern. This is convenient when the consumer cuts and stitches the patchwork fabric.

  Moreover, according to the said Example 4, the pattern which reduced the whole lattice pattern to one square among the some squares which comprise a lattice pattern is printed. Therefore, a consumer who wants to purchase a fabric for patchwork can grasp the entire image only by looking at the square portion of the reduced pattern. As a result, even when the patchwork fabric is folded when sold at a handicraft store, the patchwork fabric is expanded to expand the entire patchwork fabric even if the reduced pattern section appears on the surface. Consumers can purchase without checking colors and colors.

  From the above, in the present invention, a plurality of cloth pieces having a size to be combined with patchwork are arranged in one kind of cloth, and the patterns and colors of the cloth pieces are changed, respectively. The cloth piece set required for patchwork can be obtained simply by cutting the cloth piece, and a patchwork cloth with less waste such as a cut residue can be provided.
