Description

Technical Field

[0001] The present application relates to the field of textile technology, and in particular to a patterned jacquard fabric and a manufacturing method thereof. Background Art

[0002] Picture-based jacquard fabrics, also known as woven pictures, are fabrics created using computer graphics technology using a colorful pattern as the base. These designs are woven on electronic jacquard looms. These pictures are made by interweaving a single warp yarn system with multiple weft yarn systems. The warp yarns on the loom are relatively fixed, typically black or white, while the color of the picture is primarily determined by the weft yarns. Electronic jacquard looms typically use eight weft colors (eight color shuttles).

[0003] Traditionally, there are two approaches to weaving painting: block-based and dot-based. Block-based, also known as weave gradient design, is suitable for patterns with distinct color blocks, few basic hues, and large areas of lightness or hue gradients. Block-based weave gradient design requires the processed image to be block-shaped, with blocks of varying color levels utilizing a series of gradient wefts to enhance the satin weave, achieving a "gradation of hue or lightness from one weft color to another." Dot-based, also known as digital jacquard design, is suitable for patterns with a rich, mixed color palette and distinct dot patterns. Dot-based digital jacquard design requires the processed image to be dot-shaped, relying on dithering of custom color dots.

[0004] For jacquard fabric production, electronic jacquard looms are divided into flat and satin looms. The single-point digital jacquard method, suitable for flat looms, has a pixel count of 1 across the warp yarns. During image processing, the width pixel value equals the number of warp yarns. The weft density is generally 32-36 threads / cm, with a total pixel count of approximately 1844-2074 pixels per square centimeter. The double-point digital jacquard method, suitable for flat looms, has a pixel count of 2 across the warp yarns. During image processing, the width pixel value equals half the number of warp yarns. The weft density is generally 42-48 threads / cm, with a total pixel count of approximately 1209-1382 pixels per square centimeter.

[0005] However, the aforementioned digital jacquard single-point weaving method is not suitable for mesh shuttle weaving. Without mesh shuttle weaving, the weft yarns on the back of the fabric will be too long, affecting fabric quality and subsequent ironing. If mesh shuttle weaving is used, the mesh shuttle point will be located in an area where the number of pixels across the warp yarns is 1, resulting in dew points and ruining the fabric's image. The digital jacquard double-point weaving method can use mesh shuttle weaving, but the number of pixels per unit area is less than that of the single-point method, resulting in a less refined and slightly rougher pattern. Summary of the Invention

[0006] Based on this, it is necessary to provide a picture jacquard fabric and its production method to address the problems that the digital jacquard single-point method is not suitable for mesh shuttle, and the digital jacquard double-point method can be used for mesh shuttle but its pattern expression is not fine enough.

[0007] The first aspect of the present application provides a method for manufacturing a pictorial jacquard fabric, wherein the fabric has intermediate color positions with fixed interval values along the weft direction. The method for manufacturing the pictorial jacquard fabric comprises: obtaining structural information and an initial image of the fabric, and determining an interval value based on the initial image; determining the width pixels and height pixels of the initial image according to the structural information and the interval value; performing image subtraction processing on the initial image through an indexed color mode and custom color dithering to obtain a first preprocessed image; adding intermediate color positions to the first preprocessed image according to the interval value to obtain a second preprocessed image; performing tissue planning processing and mesh processing on the second preprocessed image; wherein the interval value is 1 or 2, the control rule of the tissue planning processing is that the minimum number of warp yarns spanning the weft yarn float length constituting the fabric surface pattern is 2, and the mesh processing includes that the minimum warp yarn distance between the weft floating point position and the mesh weave point position constituting the fabric surface pattern is 1.

[0008] In some embodiments, the fabric structural information includes pattern design method, loom type, fabric width, fabric length, warp density, weft density, warp yarn color, weft yarn color, yarn count and material, and post-weaving processing type.

[0009] In some embodiments, determining the width pixels and height pixels of the initial image according to the structural information and the interval value includes: px1= ; When the interval value is 1, px2= ; When the interval value is 2, px2= ; Where px1 is the height pixel of the initial image, px2 is the width pixel of the initial image, a is the weft density, b is the fabric length, c is the warp density, and d is the fabric width.

[0010] In some embodiments, the custom color includes custom color dithering and base color dithering.

[0011] In some embodiments, adding an intermediate color bit to the first pre-processed image to obtain a second pre-processed image includes: when the left and right primary colors of the intermediate color bit are the same color, the color value of the intermediate color bit is the same as the left and right primary colors; when the left and right primary colors of the intermediate color bit are different colors, the color value of the intermediate color bit is an intermediate color between the left and right primary colors, and the number of intermediate colors e= ; Where f is the number of primary colors.

[0012] In some embodiments, adding intermediate color bits to the first pre-processed image to obtain the second pre-processed image further includes: adding intermediate color bits starting from the second column of the first pre-processed image.

[0013] In some embodiments, adding intermediate color bits to the first preprocessed image to obtain the second preprocessed image further includes: when the interval value is 1, staggeredly adding intermediate color bits starting from the 2nd column of odd rows and the 3rd column of even rows; when the interval value is 2, forming a group with rows 1, 2, and 3 spaced 2 rows apart, and alternately adding intermediate color bits starting from the 2nd, 3rd, and 4th columns in each group, or randomly alternatingly adding intermediate color bits starting from the 2nd, 3rd, and 4th columns.

[0014] In some embodiments, adding an intermediate color bit to the first preprocessed image to obtain the second preprocessed image further includes: when the last column of the second preprocessed image is the intermediate color bit, the color of the pixels in the last column is the same as the color of the pixels in the column before the last column.

[0015] In some embodiments, performing weave planning processing on the second pre-processed image includes: performing weave planning processing on color blocks or color dots of the main color in the second pre-processed image according to the weft weave.

[0016] In some embodiments, the method for making a patterned jacquard fabric also includes weaving and / or forming processing, wherein weaving includes making an electronic pattern plate, weaving and dividing the fabric into strips using a loom, and forming processing includes shearing or laser cutting the fabric into individual pieces according to a preset contour shape.

[0017] A second aspect of the present application provides a picture jacquard fabric, which is prepared by the method for preparing the picture jacquard fabric in any of the above embodiments.

[0018] In the aforementioned method for producing a patterned jacquard fabric, the minimum warp length of the weft float in the fabric surface pattern is set to 2, effectively covering the weft points. Furthermore, the minimum warp distance between the weft float points and the weft points is set to 1, staggering the weft float points and preventing the weft points from adhering to the weft float points of the same color shuttle. Consequently, the weft floats on the back of the fabric are kept uncluttered, thus preventing the fabric from being cluttered and affecting subsequent processing. Furthermore, compared to the digital jacquard double-dot method, the method for producing a patterned jacquard fabric in this application has 20%-33% more pixels per unit area, improving the fineness and clarity of the pattern.

Example 1

[0026] The present application provides a method for manufacturing a patterned jacquard fabric, the method comprising the following steps:

[0027] S100: Acquire structural information and an initial image of the fabric, and determine an interval value based on the initial image.

[0028] The structural information of the fabric includes pattern design method, loom type, fabric width, fabric length, warp density, weft density, warp yarn color, weft yarn color, yarn count and material, and post-weaving processing type.

[0029] The interval value is a step value for adding the intermediate color positions to the initial image of the picture jacquard fabric along the weft direction, and the interval value is 1 or 2. When the interval value is 1, it is referred to as interval 1 plus 1, and when the interval value is 2, it is referred to as interval 2 plus 1.

[0030] The picture jacquard fabric has intermediate color positions with fixed interval values along the weft direction, and the intermediate color positions are used to express the common position of two adjacent weft colors of the picture jacquard fabric pattern.

[0031] For example, a jacquard fabric with a pictorial image of Kanas scenery, with a rich and diverse array of colors, uses a digital jacquard design method that simulates full color using eight basic colors. The fabric is woven on a flat loom, with a fabric length of 10 cm and a width of 6.67 cm. The warp density is 57.6 threads / cm, and the weft density is 48 threads / cm. The width of the jacquard design is the product of the warp density and the fabric width, i.e., 57.6 threads / cm * 6.67 cm ≈ 384 pixels. The height of the jacquard design is the product of the weft density and the fabric length, i.e., 48 threads / cm * 10 cm fabric length = 480 pixels. The warp yarns are 50D white, the weft yarns are 50D, and there are eight color shuttles: white, magenta, red, yellow, green, cyan, blue, and black. In this embodiment, the spacing value is 2, i.e., 2 plus 1 in the weft direction based on the initial image.

[0032] S200 : Determine the width and height of the initial image in pixels according to the structure information and the interval value.

[0033] The height pixels of the initial image are the product of the weft density and the fabric length. When the interval value is 1, the width pixels of the initial image are half of the product of the warp density and the fabric width. When the interval value is 2, the width pixels of the initial image are two-thirds of the product of the warp density and the fabric width.

[0034] Specifically, an original image of a pictorial jacquard fabric is imported into image processing software. The image orientation is adjusted so that the width direction equals the X coordinate, the weft direction equals the row direction, and the height direction equals the Y coordinate, the warp direction equals the column direction. Based on the interval value of 2 determined in step 100, the warp density, and the desired weft density, the width and height of the initial image of the pictorial jacquard fabric are determined. The width of the initial image of the pictorial jacquard fabric is not equal to the width of the pattern design. When the interval value is 2, the width of the initial image is calculated as follows: 57.6 warp threads / cm x 6.67 cm fabric width / 3 x 2 = 256 pixels. The height of the initial image is calculated as 480 pixels = 480 weft threads / cm x 10 cm fabric length.

[0035] S300 , performing image color subtraction processing on the initial image by using an index color mode and user-defined color dithering to obtain a first pre-processed image.

[0036] A loom typically has eight color shuttles. Regardless of the number of colors in the image, the fabric can only be produced using eight yarn colors. To achieve the rich colors of the image using a limited number of weft yarn colors, the image must be processed using subtractive color.

[0037] Using the "Indexed Color Mode" in image processing software, a custom color and dithering are applied to the initial image to produce the first pre-processed image. Custom colors, also known as "forced colors," are the colors of the weft yarns and are known as primary colors. Their number should not exceed the number of color shuttles on the loom. In Indexed Color Mode, if a color in the original image does not appear in the "forced color" table, the program will select the closest color from the existing "forced color" table. Alternatively, the program will use a color from the existing "forced color" table and apply color dithering (diffusion dithering) to alter the pixel arrangement to simulate that color. The diffusion dithering amount is typically 70%-100%.

[0038] Custom colors can be created in two ways based on the image's color characteristics. One is custom color dithering, which selects a custom color based on the image's primary colors. The other is basic color dithering, which uses the physiological four primary colors (red, yellow, blue, and green) plus black and white to simulate full color, or uses the eight basic colors (white, magenta, red, yellow, green, cyan, blue, and black) expanded from the three primary colors to simulate full color. To maximize the simulation of various hues, basic color dithering can be used, such as using the eight basic colors (white, magenta, red, yellow, green, cyan, blue, and black) expanded from the three primary colors to simulate full color. To save costs, the four physiological primary colors (red, yellow, blue, and green) plus black and white can be used to simulate full color. In this embodiment, the eight basic colors (white, magenta, red, yellow, green, cyan, blue, and black) are used as mandatory colors.

[0039] The experience of adjusting the amount of diffuse dithering is that the color point distribution is more reasonable and the main pattern has no obvious defects. In this embodiment, the amount of diffuse dithering is 94%.

[0040] S400 , adding intermediate color bits to the first preprocessed image according to the interval value to obtain a second preprocessed image.

[0041] Based on the first preprocessed image, a script is used to add intermediate color sites starting from the second column of the image to generate the second preprocessed image. When the left and right primary colors of the intermediate color site are the same, the color value of the intermediate color site is the same as the left and right primary colors. When the left and right primary colors of the intermediate color site are different colors, the color value of the intermediate color site is a mixture of the two primary colors, also called the intermediate color.

[0042] The mixed color can be calculated using the RGB color model as follows:

[0043] Mixed color R = (left color R + right color R) / 2

[0044] Mixed color G = (left color G + right color G) / 2

[0045] Mixed color B = (left color B + right color B) / 2

[0046] The number of intermediate colors = the number of primary colors * (the number of primary colors - 1) / 2. In this embodiment, there are 8 primary colors and 28 intermediate colors.

[0047] When the last column of the second preprocessed image is an intermediate color, the color of the pixels in this column is the same as the color of the pixels in the previous column.

[0048] In some embodiments, the starting bit for adding intermediate color bits may be fixed to the second column.

[0049] In some embodiments, intermediate color bits may be added to the first pre-processed image according to an interval value to obtain a second pre-processed image. Specifically, when the interval value is 1, the starting bits to be added are the second and third columns, respectively, and the intermediate color bits are added in a staggered manner, starting with the second column of odd rows and the third column of even rows. When the interval value is 2, the starting positions for adding intermediate color bits are the 2nd, 3rd, and 4th columns, respectively. Rows 1, 2, and 3 are grouped together with rows spaced 2 rows apart. Within each group, intermediate color bits are added alternately starting with the 2nd, 3rd, and 4th columns. For example, in this embodiment, the interval value is 2. Intermediate color bits are added starting with the 2nd column for row 1, the 3rd column for row 2, the 4th column for row 3, and the 2nd column for row 4. This alternating process repeats, i.e., intermediate color bits are added starting with the 2nd column for rows 1, the 3rd column for rows 2, the 4th column for rows 3, the 4th column for rows 4, and the 2nd column for rows 1. Alternatively, you can randomly add intermediate color bits starting from the 2nd, 3rd, and 4th columns. For example, the 1st, 4th, 7th, ... rows start adding intermediate color bits from the 3rd column, the 2nd, 5th, 8th, ... rows start adding intermediate color bits from the 4th column, and the 3rd, 6th, 9th, ... rows start adding intermediate color bits from the 2nd column. That is, each group of rows can start adding intermediate color bits from any of the 2nd, 3rd, and 4th columns.

[0050] Adding intermediate colors to the image based on the interval value results in more staggered and offset intermediate colors than adding them starting from the second column. This staggering and offsetting of intermediate colors allows the colors to appear on different warp yarns, improving the appearance of fabric color. Furthermore, adding intermediate colors to the image based on the interval value ensures uniform warp tension.

[0051] The second pre-processed image is saved in a bitmap format, such as BMP format.

[0052] S500: Perform tissue planning processing and net shuttle processing on the second pre-processed image.

[0053] This step is also a flower-printing processing step. Specifically, the second pre-processed image is imported into the flower-printing software, and color sorting processing can be performed first to adapt to the calling of the organization function template function of the flower-printing software.

[0054] Next, the color block weave is planned. The primary color blocks or dots are arranged according to the weft weave. Intermediate color dots are located between the two adjacent weft colors. This ensures that the minimum weft float length for the fabric surface pattern is two warp yarns, effectively covering the weft dots. From the perspective of the surface pattern, adjacent weft colors occupy a half-pixel position at this location, with the minimum pixel size being 1.5.

[0055] Then the mesh shuttle processing is carried out, and the minimum warp yarn distance between the weft floating points that constitute the fabric surface pattern and its mesh shuttle points is 1, so as to avoid the mesh shuttle points sticking to the weft floating points of the adjacent shuttle of the same color and affecting the pattern.

[0056] The method for making the picture jacquard fabric also includes:

[0057] S600, weaving.

[0058] Weaving includes making electronic patterns, weaving on a loom and dividing into strips.

[0059] S700, forming processing.

[0060] The forming process involves shearing or laser cutting individual pieces of fabric according to a pre-defined contour.

[0061] like Figure 1 As shown, in this embodiment, a 2 plus 1 pattern jacquard fabric can be obtained by the above method.

[0062] Based on Example 1, the method for making a patterned jacquard fabric is compared with the single-point method and the double-point method suitable for weaving on a flat machine:

[0063]

[0064] Graphic jacquard fabrics adhere to the "theory of spatial color mixing": when juxtaposed or closely spaced color dots or lines are placed at a certain visual distance, if their projected size on the retina is smaller than the diameter of the color-receptor cells, the human eye cannot distinguish them, resulting in a blending effect. This creates a blurred visual effect, akin to "mixed colors in one area." The effectiveness of spatial color mixing is also dependent on visual distance; the farther the distance, the more pronounced the blending effect. This is often referred to as "distance creates beauty."

[0065] To achieve spatial blending of the colors of the yarn segments on a graphic jacquard fabric, the yarn segments must be densely arranged as fine dots or lines. Digital jacquard uses custom-colored dots and dithering to mimic color. In image processing, the more pixels per unit area, the more realistic the pattern and the sharper the details.

[0066] As can be seen from the above table, compared with the double-point method, the 2 plus 1 method in this embodiment has about 33% more pixels per unit area, which improves the fineness and clarity of the pattern; compared with the single-point method, the 2 plus 1 method in this embodiment can perform mesh shuttle, and the weft yarn on the back of the fabric is not messy, which is suitable for subsequent processing such as ironing.

[0067] Example 2

[0068] The present application provides a method for manufacturing a patterned jacquard fabric, the manufacturing method comprising the following steps:

[0069] S100: Acquire structural information and an initial image of the fabric, and determine an interval value based on the initial image.

[0070] The original image of a graphic jacquard fabric is a small crocodile. The image has few hues and a patchwork of color dots. A custom color imitation design method was used for digital jacquard fabric, selecting the four primary colors in the image as custom colors. The fabric was woven on a flat loom, with a length of 14.5 cm and a width of 6.67 cm. The warp density was 57.6 threads / cm, and the weft density was 57.6 threads / cm. The width of the graphic design was calculated as 384 pixels for the warp density of 57.6 threads / cm * 6.67 cm for the width of the fabric, and 840 pixels for the weft density of 57.6 threads / cm * 14.5 cm for the length of the fabric. The warp yarns were 50D white, and the weft yarns were 50D. Four color shuttles were used: white, yellow, gray, and black. In this example, the spacing value was 1, meaning the spacing along the weft direction was incremented by 1 based on the initial image.

[0071] S200 : Determine the width and height of the initial image in pixels according to the structure information and the interval value.

[0072] When the interval value is 1, the width pixels of the initial image are 57.6 warp threads / cm*6.67 cm fabric width / 2≈192, and the height pixels of the initial image are 57.6 weft threads / cm*14.5 cm fabric length≈840.

[0073] S300 , performing image color subtraction processing on the initial image by using an index color mode and user-defined color dithering to obtain a first pre-processed image.

[0074] In this embodiment, the image has few hues and can use custom color dithering, that is, select the main color in the image as the custom color, white, yellow, gray, black. Its advantage is that it uses fewer colors and the main color stands out.

[0075] The experience of adjusting the amount of diffuse dithering is that the color point distribution is more reasonable and the main pattern has no obvious defects. In this embodiment, the amount of diffuse dithering is 92%.

[0076] S400 , adding intermediate color bits to the first preprocessed image according to the interval value to obtain a second preprocessed image.

[0077] In this embodiment, the interval value is 1, and the starting added bits are the 2nd column and the 3rd column respectively. The intermediate color bits are staggered and added starting from the 2nd column of odd rows and the 3rd column of even rows.

[0078] When the left and right main colors of the intermediate color locus are the same color, the color value of the intermediate color locus is the same as the left and right main colors; when the left and right main colors of the intermediate color locus are different colors, the color value of the intermediate color locus is a mixture of the left and right main colors, which is called the intermediate color.

[0079] The mixed color can be calculated using the RGB color model as follows:

[0080] Mixed color R = (left color R + right color R) / 2

[0081] Mixed color G = (left color G + right color G) / 2

[0082] Mixed color B = (left color B + right color B) / 2

[0083] The number of intermediate colors = the number of primary colors * (the number of primary colors - 1) / 2. In this embodiment, there are 4 primary colors and 6 intermediate colors.

[0084] When the last column of the second preprocessed image is an intermediate color, the color of the pixels in this column is the same as the color of the pixels in the previous column.

[0085] The second pre-processed image is saved in a bitmap format, such as BMP format.

[0086] S500: Perform tissue planning processing and net shuttle processing on the second pre-processed image.

[0087] The second pre-processed image is imported into the flower drawing software, and color sorting processing can be performed first to adapt to the calling of the organization function template function of the flower drawing software.

[0088] The color block weave is then planned. The primary color blocks or dots are arranged according to the weft weave. The intermediate color dots are located between the two adjacent weft colors on the left and right, ensuring that the minimum weft float length across the warp yarns that form the fabric surface pattern is 2. From the perspective of the surface pattern, adjacent weft colors occupy a half-pixel position at this location, with the minimum pixel count equivalent to 2.

[0089] Then the mesh shuttle processing is carried out, and the minimum warp yarn distance between the weft floating points that constitute the fabric surface pattern and its mesh shuttle points is 1, so as to avoid the mesh shuttle points sticking to the weft floating points of the adjacent shuttle of the same color and affecting the pattern.

[0090] The method for making the picture jacquard fabric also includes:

[0091] S600, weaving.

[0092] Weaving includes making electronic patterns, weaving on a loom and dividing into strips.

[0093] S700, forming processing.

[0094] The forming process involves shearing or laser cutting individual pieces of fabric according to a pre-defined contour.

[0095] like Figure 2 As described above, in this embodiment, a 1+1 pattern jacquard fabric can be obtained by the above method.

[0096] Based on Example 2, the method for making a patterned jacquard fabric is compared with the single-point method and the double-point method suitable for weaving on a flat machine:

[0097]

[0098] It can be seen from the above table that, compared with the double-point method, the 1 plus 1 method in this embodiment has enhanced weft surface coverage, less exposed warp, improved weft density, and about 20% more pixels per unit area, thereby improving the fineness and clarity of the pattern; compared with the single-point method, the 1 plus 1 method in this embodiment can perform mesh shuttle, and the weft yarn on the back of the fabric is not messy, which is suitable for subsequent processing such as ironing.

[0099] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
