Description

  The present invention relates to a photographic towel fabric in which a photographic texture expression portion and a non-photographic woven texture portion are provided in a photographic pattern expression portion, and a method for weaving a photographic towel fabric.

  As a woven fabric that expresses a photo-like pattern with wefts, a matrix structure diagram is created that simulates the number of colors with a limited intermediate color tone by dithering based on image data captured by a computer. Photo weaving has been proposed in which one of the allocated and weft yarns is selected as a warp yarn (see, for example, Patent Document 1 or Patent Document 2). However, this method is different from the method of weaving a photographic-like woven fabric by the color density because the color reduced by the application of the Gobelin weave is the weft and one of the weft yarn is the warp.

  In addition, a part of the pile warp on the front or back side of the double-sided pile (Wana) towel cloth is moved to the back side or the front side, a non-pile area is provided on the front or back side, and a pattern or the like is expressed by the non-pile area. Has been proposed (see, for example, Patent Document 3). In the invention described in Patent Document 3, a pile warp is brought to either the front surface or the back surface to form a non-pile surface. Therefore, a plurality of pre-dyed yarns are used as a part of the weft to inject and use a photographic pattern. There was a problem that it was impossible.

Therefore, the inventor of the present application repeatedly researched day and night, developed the inventions related to Patent Document 4 and Patent Document 5, and applied for a patent. The invention according to Patent Document 4 reads a photograph or the like into a computer as full-color or monotone image data, enhances the contrast of the full-color or monotone image data, removes a high-frequency component, and reduces the color to use. Towel loom according to the weaving data created by selecting the color within the limited number, assigning the selected color to the weft or upper warp and converting the image data by the computer with the color yarn information and density information input Is driven, and the weft or upper warp is exposed on the surface of the towel fabric, and a method for weaving a photographic fabric having a perspective by gradient. In the invention according to Patent Document 5, full-color image data captured by a computer is color-separated by adding white to CMYK, and the density difference of each of C, M, Y, and K is half-tone separated into two gradations of black and white. Integrate four image signals converted to black and white, reduce the color within the limited number of towel loom color yarns used, assign the colored yarn dyed to the reduced color to the weft yarn or the upper warp yarn, A full-color image captured by the computer by driving the towel loom according to the weaving data created by converting the image data by the computer into which the information and density information are input, and displaying the weft or upper warp on the surface texture of the towel fabric. The present invention relates to a method for weaving a full-color photographic fabric approximated to data.
However, in the invention according to Patent Document 4 or Patent Document 5, the kite can hit the weft yarn before weaving and determine the density of the weft yarn, and the towel loom itself can adjust the yarn density to a desired density (high density). Function). When weaving towels at a high density using the density adjustment function of towel looms, the towel loom is physically burdened, and when towels are woven at ultra high speed, the performance of the towel loom cannot catch up and a pile is formed. There was a problem that it was not done. In this way, when the separation color is a weft, the pattern can be woven with high density and high accuracy, whereas the towel loom does not have the function of reducing the distance between the upper warps and increasing the density, When weaving a pattern with warps pre-dyed to the separation color, there is a problem that the lateral distance between the warps is long and it is impossible to weave a high-precision photographic fabric. Further, the invention described in Patent Document 4 or Patent Document 5 cannot be formed by simultaneously mixing the photo-like pattern expression of the satin weave and the pile which is a basic characteristic of the towel.

In addition, in order to use the upper warp yarn pre-dyed in the separation color, it is necessary to wrap the upper warp yarn pre-dyed in different colors around the nove in the correct order as the previous step, Requires a long period of about one week on outsourcing. After winding the upper warp around the nove, use a crane or pulley to attach the nove to the towel loom, and even after attaching the nove to the towel loom, work to connect thousands of upper warps one by one to the hook. It has the disadvantage that it requires a lot of labor and time.
In addition, when weaving the pattern portion with warp, there is a drawback that it is difficult to calculate the amount of yarn wound around the drum and to predict the finished product. The amount of yarn to be wound around the sleeve is determined by taking into consideration the elasticity of the cotton yarn and the occurrence of defective products, but the extra length of warp is wound, but the number of towels is not necessarily finished as the warp usage is calculated. The excess or deficiency occurs. This has the disadvantage that it always results in excess inventory in order to weave the necessary towels.
In addition, the color separation of the photograph is a fine separation, and unless the towel fabric is completed, the accuracy of the photograph is not known. First, it is necessary to present a sample to the customer. The nove has a diameter of about 30cm, and considering the distance to the towel loom, the distance between the nove and the machine is about 1m. It is wrapped around the outer periphery of the nove and the amount of yarn required for towel weaving is towel 1. The length of the warp used for the sheet is exceeded. For this reason, when weaving one sample to confirm the accuracy of color separation of the color-separated image data, the extra yarn wrapped around the outer periphery of the nove must be disposed of, resulting in labor costs, yarn There is a disadvantage that waste of electricity, electricity, time, etc. occurs. Photo-style towel fabrics using warp yarns have the disadvantages of being in a large number of lots, increasing labor costs and increasing the risk of excess inventory.

In addition, when image data is color-separated and pre-dyed yarns dyed into the weft yarn or the selected color are used and the weft yarn is expressed to express a photographic pattern, the weft yarn is connected to an accumulator which is a weft injection motor. Weaving can be started in about 5 minutes. For this reason, weaving can be started only by changing the weft to the accumulator if there is an error in the dyeing and ordering of the colored yarn or if only one sheet is ordered, as long as various types of colored yarn are prepared as weft. Therefore, it has the advantage of being able to respond to small lot orders immediately. Even if it is determined that photo disassembly has failed after weaving the sample, we can correct the photo towel fabric by connecting the weft to the accumulator in a few minutes. It is possible to reduce the price and speed up the finish.
However, when weaving photographic patterns with wefts, the wefts float long in the horizontal direction, and there are disadvantages that the fabric becomes a flat and rugged flat fabric without pile, and because there is no pile, the touch is poor and the water absorption is also reduced. It was.
Japanese Patent Publication No.7-88610 Japanese Patent Publication No. 7-88608 JP 2004-183144 A JP 2006-152520 A JP 2006-2198110 A

  The problem to be solved is that when a photographic pattern is woven only with wefts, a structure without a pile is a flat fabric that cannot be called a towel.

The invention according to claim 1 is a photograph in which a ground fabric and a weft are interlaced to form a towel fabric, and a towel fabric is provided with a photographic pattern expression portion on a towel fabric in which a pile is formed by upper warps and / or lower warps. It is a wind towel fabric, and the photographic pattern expression portion is a pile formed of a set of a plurality of colored yarns dyed in each color specified by color separation of the original pattern of the photographic pattern expressed on the towel fabric. Towel fabric is arranged as a weft between the upper and lower warp yarns in the portion, and the photographic-like pattern expressing portion is alternately arranged in the vertical direction with the photographic woven texture portion and the non-photo woven texture portion. in order to have as a whole photograph of Fugara represented pile photographic weave portion while maintaining of the said photographic woven structure portion forms a pile on the back side in the upper warps, the 1 For the design of the colored thread Only the necessary color yarn is placed on the lower warp and exposed on the surface side to express the photographic pattern, and the remaining color yarn unnecessary for the expression of the photographic pattern is hidden between the lower warp and the upper warp The non-photo-textured texture portion is characterized in that the set of colored yarns are concealed between an upper warp and a lower warp to form a pile on the front surface and / or the back surface.
The invention according to claim 2 is a photographic-style towel weaving method for weaving a towel fabric provided with a photographic-style pattern expression portion on a towel loom using computer-processed data. Optically read and image data is captured into a computer with pixel adjustments corresponding to towel loom data used by the resolution, and the captured image data is color-separated, and the photo-like pattern of the separated colors A step of specifying a plurality of colors within the range of a limited number of color yarns of a towel loom to be used, and a photo weaving having the predetermined image width and extending in the horizontal direction. The process of dividing the tissue part and the non-photo-woven structure part having a predetermined vertical width and extending in the horizontal direction alternately into horizontal stripes along the vertical direction, the color information of the towel loom used, and the color Disassembled A process of inputting longitudinal woven texture information obtained by dividing image data into a photographic woven texture portion and a non-photographic woven texture portion to a computer, and converting the image data based on the color yarn information and the longitudinal woven texture information. The towel loom is driven in accordance with the created weaving data, and the image data is color-separated to identify a plurality of identified lines at the position where the pile portion consisting of upper warp and / or lower warp straddles in the photographic pattern expression portion. A set of colored yarns are injected and arranged, and in the photographic textured portion of the photographic pattern expression portion, the color yarns necessary for the photographic pattern expression of the set of colored yarns are pushed up by lower warp yarns and are placed on the lower warp yarns. The other color yarns, excluding the color yarn pushed up to the front side of the set of color yarns, are piled on the back side with an upper warp yarn, A pile made of warp and the lower warp And arranged concealed between, in the non-photographic weave portion, characterized in that so as to conceal by arranging the set of colored yarn between said warps and lower warp yarns.

In the present invention, in the photographic pattern expression portion, a photo woven structure portion and a non-photo woven structure portion are alternately provided in the longitudinal direction on the front side, and the upper warp is pulled out on the back side and a pile is formed on the back side in the photo woven structure portion. Since it forms and conceals unnecessary colored yarn inside the pile, it has a pile-like shape as a towel fabric, and there is no tingling sensation required as a basic function of the towel while maintaining a dense photographic pattern It has the effect of having a soft touch and water absorption characteristic of piles.
Since wefts of weft are packed in a high density in the vertical direction, the colored yarns that float on the surface are arranged in a high density in the vertical direction in the photo weaving structure part, exhibiting a dense pattern, and also a photo-like pattern expression part In the non-phototextured tissue part, piles are densely formed in the vertical direction, and the vertical width of the non-phototextile structure part is narrowed, and the photographic-like pattern is blurred as a whole due to the existence of the non-phototexture structure part. There is an effect that a precise pattern can be expressed.
Compared to the fact that the weaving start preparation period when weaving a photographic pattern with upper warp is about 1 week, it is sufficient for the present invention to connect the color yarns necessary for expression to the accumulator, respectively. The weaving start preparation time only takes a short time of about 5 minutes, so that the time required for the weaving preparation can be remarkably shortened, and it is possible to respond immediately to a small lot order.
Also, if you notice a specific error in the color yarn after weaving, it can be corrected by changing the color yarn to the accumulator in several tens of seconds. There is an effect that it is possible to perform the work for correcting the replacement of the colored yarn in a short time of only a few tens of seconds. Therefore, there is an effect that weaving can be completed very easily in a short time for the sample presented to the customer.

For the purpose of having both a photo weave texture part and a non-photo weave texture part in the photographic pattern expression part, a set of a plurality of color yarns dyed in the photo separation color on the weft straddling the pile is used as a set In the tissue part, one of the set of colored yarns that is necessary for the expression of the photographic pattern is pushed up to the front side with the lower warp. Wrapped in a pile of upper warps formed on the side, concealed and woven, and in the non-photographic weave structure part, one set of colored yarn is concealed between the upper and lower warps, making it difficult to see the ground structure from the outside In order to express the photographic style , the photographic style expression was realized with the colored threads that appeared on the surface.

  In this way, in the photo weaving structure portion 4, the lower warp 33 pushes up only the color yarn necessary for pattern expression out of the set of the color yarns 10, 11, 12, 13 to the surface side, and the remaining three unnecessary yarns As for the colored yarn, a pile is formed on the back side with the upper warp 32, and the remaining three unnecessary color yarns are concealed with the pile, and the pile formed on the front side with the upper warp 32 in the non-photograph texture portion 5 And a set of colored yarns 10, 11, 12, and 13 are concealed inside the pile formed on the back side by the lower warp yarn 33.

3 adjacent weft yarns, that is, a set of weft yarns 7, 8, 9; a set of ground weft yarns 14, 15, 16; a set of ground weft yarns 17, 18, 19; a set of ground weft yarns 20, 21, 22; In the set of ground wefts 23, 24, and 25, and the set of ground wefts 26, 27, and 28, the three ground wefts in each set are woven so that the towel fabric structure is hardly visible from the outside. Therefore, the photo-woven tissue portion 4, and more colored threads which presented on the surface, thereby improving the accuracy of the pattern.

  A second embodiment shown in FIG. 3 will be described. The pile towel cloth 1 is provided with a non-photographic woven tissue portion 5 in which a pile is formed on the surface side around the photographic pattern expression portion 34. The entire photographic pattern expression portion 3 is formed in the photographic texture portion 4. That is, the surface side is made of satin weave which is necessary to express the photographic style of the colored yarns 10, 11, 12 and 13 in the surface side, and the back side is formed into a pile by the upper warp 32. The remaining colored yarn not exposed in the pile is concealed and woven. The non-photo woven structure portion 5 is woven into a double-sided pile, but may be a single-sided pile.

A method for weaving photographic towel fabric will be described with reference to FIGS. 1, 2, and 4 to 7.
As shown in FIG. 4, first, design data for the entire towel fabric such as which portion of the towel fabric is provided with a photographic pattern expression portion is created.

  A process of taking a photograph or the like as a basis of a photographic pattern expression portion in a towel fabric into a computer will be described. An image using a lot of gradients such as photographs and pictures is read by an image input device such as a color scanner, and is captured as full-color or monotone digital image data in a computer. In the case of capturing image data, it is necessary to perform pixel adjustment that correlates the relationship between the pixel and the length of the towel loom used and the pattern mouth. In other words, one pixel is regarded as data on the top and bottom of the yarn, where the pixel exists, the yarn structure is also set, and the pixel adjustment is performed so that the resolution corresponds to the data of the towel loom to be used. If pixel adjustment is not performed, halftone dots will be erased as loom data even if the halftone dots in the photo are adjusted, and the portion where the pseudo gradient is created will be erased by halftone processing. That is why.

  The captured full-color or monotone image data is subjected to image adjustment for enhancing contrast. Adjusts the color shade by amplifying the brightness and color difference of the screen. When the pixel density f (x, y) at the position (x, y) of the original image is set as the density g (x, y) in the processed image (x, y) and the density of the image, that is, the brightness is multiplied by n, These relationships are g (x, y) = n × f (x, y). The image data is full color at the contrast enhancement stage. In the case of 8 bits per pixel, the representable density range is 0 to 255, and if the calculated value exceeds 255, the value is limited to 255. Therefore, if the value of n is increased, the image data becomes white. Therefore, the value of n is selected while adjusting the contrast of the actual image.

Next, the color reduction process will be described.
For example, R, G, and B are each reduced to 1 bit = 8 colors (2 (R) × 2 (G) × 2 (B)). That is, high frequency components that are difficult to be clearly recognized by human eyes are deleted. As specific examples of this deletion method, run-length code, predictive coding (DPCM), Huffman coding, and the like can be considered. When the graphic VRAM has a capacity of 4 bits per pixel, 2 ⁴ = 16 types of palettes can be used, and grayscale information of 16 colors can be assigned. Each of R, G, and B is displayed with 2 ⁴ = 16 colors. In the case of color reduction, when a specific color is expressed, R, G, and B may be reduced by 2 bits or more, that is, 2 ² × 2 ² × 2 ² = 64 colors or more in order to give a wide selection of colors. Conceivable.
For example, in the case of a towel loom that can use only six colors, if one weft is used for the pile portion in the hair, the remaining five colors are assigned to the weft in the border portion. In the initial state of the graphic, each palette color is 0: black, 1: light blue, 2: light red, 3: light yellow, 4: light green, 5: light light blue, 6: light yellow, 7: light gray, 8: Dark gray, 9: blue, 10: red, 11: purple, 12: green, 13: light blue, 14: yellow, 15: white are set. At this stage, unnecessary colors are removed to create a photographic fabric. Taking the case of using a black-and-white photo as an example, the shading information is black for the first color used as the darkest shadow part of the photo, palette 0: R (0) G (0) B (0), and the second color for light. White used as the brightest part that hits, Palette 15: R (15) G (15) B (15), the third color is dark gray, which is a gradient of the first and second colors, Palette 3: R (3) G (3) B (3), the fourth color is neutral gray, palette 7: R (7) G (7) B (7), the fifth color is light gray, palette 12: R (12) G (12) B ( 12) and assigning palette numbers and R, G, and B makes it possible to create a photographic fabric of five colors as pseudo colors. When producing a monotone photographic fabric, the color closest to the palette number + R, G, B is used for the colored yarn. In addition, when creating a color photographic fabric, select the closest color aggregate from the index color converted one, and select by deleting or replacing unnecessary colors so as not to feel a sense of incongruity by graduation. Express with color. The selected colors are close in saturation and lightness, and if the saturation and lightness on the color palette are of the same system, it is easy to express like a photograph by gradient.
In Example 3, when weaving a monotone photographic pattern, the high frequency components are deleted to remove inconspicuous colors, and after subtracting the color, for example, light gray, intermediate gray, dark gray, black A four-color separation specifying four colors will be described as an example.

  As shown in FIG. 6, the decomposed image 1 is divided into a photographic woven tissue portion 4 and a non-photographic woven tissue portion 5 alternately in the vertical direction, and the divided woven tissue information is input to a computer. Specifically, the decomposed image 1 is drawn by a boundary line having a positional relationship parallel to each other in the vertical direction, and the parts separated by the drawing are alternately arranged in the vertical direction with the photo weaving tissue parts 4 and the non-photographs. The woven tissue information as the woven tissue portion 5 is input to the computer. The sorting work is not limited to the case where it is performed after color separation. The sorting operation may be performed at a stage after the photograph or the like is input to the computer and before the captured image data is color-separated.

Next, weaving data is created.
The image data has the relationship between the number of vertical and horizontal pixels and the loom data CGS pattern length and pattern, the number of horizontal pixels = pattern, and the number of vertical pixels = pattern length. Match the size of the weaving fabric. Weaving data (Jacquard data) is created in consideration of the data of the photo weaving tissue portion 4 and the non-photo weaving tissue portion 5 divided in the vertical direction of the image data.

  After the weaving data is input to the computer, the towel weaving machine, which is a jacquard machine, is driven according to the programs shown in FIGS. Normally, in order to form a pile with a set of three ground wefts, when the ground wefts are injected three times one by one according to the program shown in FIG. 5, in Example 3, as shown in the flowchart of FIG. In addition, a pile wrapping start signal is present, and the colored yarn is ejected. The necessary color yarn is lowered on the lower warp 33 and the necessary color yarn is disposed on the lower warp 33. Next, unnecessary color yarns are wrapped and concealed with a pile, and a photographic textured portion 4 having a satin weave on the surface and a pile on the back is woven. In the non-photo-textured tissue portion 5, there is a pile wrap signal, and the pile wrap needle raising is also performed at the same time, thereby forming a pile in which one set of colored yarn is concealed between the upper warp yarn 32 and the lower warp yarn 33.

While the weft is being ejected, the weaving of the towel loom is stopped so that a force acts on the weft in the direction indicated by the arrow in FIG. 7, and the three wefts are adjacent in the longitudinal direction. 7, 8, 9, ground weft yarns 14, 15, 16, ground weft yarns 17, 18, 19, ground weft yarns 20, 21, 22, ground weft yarns 23, 24, 25, weft yarns 26, 27, 28 in the weaving direction. Pressing in the reverse direction changes from the state shown in FIG. 7 to the state shown in FIG. 8, and the distance between colored yarns and piles is shortened to improve the accuracy of the photographic pattern. In addition, the arrow in FIG. 8 is a weaving progress direction.
The method of increasing the density of the longitudinal color yarns and piles is not limited to the method of stopping the weaving progress during the weft yarn injection. A method of weaving adjacent weft yarns at high density by applying a force in the direction opposite to the weaving progress of the weft yarns every injection of one weft yarn is also included in the present invention.
Full color or monotone image data optically read from a photograph or the like is separated into a set of color yarns dyed to the specified colors, and the set of color yarns is arranged as a weft at the position where the pile straddles. Then, only the necessary color yarns of one set of color yarns are exposed on the front side, and unnecessary color yarns are concealed with a pile formed on the back side to express a flat photographic pattern on the front side with wefts However, the photo-patterned expression part is alternately provided with a photo-woven texture part and a non-photo-textured texture part in the longitudinal direction (weaving direction), shortening the vertical width of the non-photo-textured texture part and holding the pile as a towel fabric. However, it has a photographic style as a whole expressed in the photographic texture portion.

In the first and third embodiments, the case where four colors are made into color threads by special color separation has been described as an example. However, all known color separation methods such as CMYK separation and RGB separation are included in the present invention, and used color separation. Corresponding to the means, the number of colored yarns is increased or decreased within the limited number of colored yarns of the towel loom used. For example, when performing color separation described in Japanese Patent Application Laid-Open No. 2006-219810, five color yarns of cyan, magenta, yellow, black, and white are used as a set of color yarns.
1, 7, and 8, the structure of one needle is explained as an example. However, in the present invention, if the adjacent wefts are packed and woven at high density, the woven structure is any structure. Also good.
