Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile design, and particularly relates to a design method of a picture-like jacquard scratch mottled texture fabric. BACKGROUND

[0002] At present, the popular appearance performance of textile fabrics mainly includes natural texture, delicate flaws, blurred and hazy, mottled patterns, and gradient dyeing, etc. The styles of "delicate flaw" and "mottled texture" break the traditional aesthetic of flat and consistent fabric, and the unique uneven texture has the effect of beauty in imperfection, which reflects a sense of mystery and interest, and is favored by consumers who pursue unique styles.

[0003] The existing public technology CN218197388U discloses a kind of ground glass texture fabric, which is prepared in a stacked manner to have a ground glass texture on the surface. The fabric is based on a base cloth, and is composed of a reinforcing layer, a wrinkling layer, a ground sand layer, an elastic layer and a printing layer in a laminated manner. The elastic layer uses the shrinkage of spandex fiber to form the wrinkling layer. However, this production and preparation method is complicated, and the fabric has poor integrality. After long-term washing, the fabric may be delaminated. In the paper "Innovative Application of Chinese Abstract Ink Patterns in Shaped Knitted Fabrics", it is mentioned that the knitted mottled texture effect is achieved by combining sesame point jacquard, open jacquard and air layer jacquard with complex patterns having a rough feel. The yarn used in the air layer jacquard has a change in elasticity or shrinkage, and the raised effect is formed by the shrinkage of the yarn. Other organization methods use floating stitch, tuck stitch and loop stitch to achieve the mottled texture effect. In addition, fancy yarns such as bulky yarn, segment-dyed yarn and thick tweed yarn are used to create a rough texture. However, this production method only simulates the texture of the fabric that needs to be expressed, and the specific imitation process is not described in detail. SUMMARY

[0004] In view of the technical problems of scratch mottled texture fabric being difficult to simulate production, the present application provides a design method of picture-like jacquard scratch mottled texture fabric, which can highlight the scratch mottled texture of the picture in a fabric-reducing manner, and is convenient, simple and easy to operate.

[0005] The present application provides a design method of picture-like jacquard scratch mottled texture fabric, which includes the following steps:

[0006] S1, selecting a picture-like picture with scratch mottled texture, marking the positions of the mottled points forming the scratch mottled texture on the picture, and calculating the scratch length pixel number;

[0007] S2, the display mode of the segment color yarn is designed as a scratch mottling texture, the color length and color distance of the segment color yarn are calculated according to the number of spot position markers and the pixel number of scratch length;

[0008] S3, in the computerized pattern design software, the process design of the pattern is carried out according to the display mode of the segment color yarn as weft yarn and in combination with the full-color organization library, and the pattern plate file after the process design is converted into a JC5 file readable by the loom.

[0009] Further, in step S1, the spots are marked by using Photoshop software, and the pixel number of the scratch length is calculated by direct measurement.

[0010] Further, in step S1, the spots distributed along the weft direction are selected and marked.

[0011] Further, in step S2, the main yarn material in the segment color yarn is cotton fiber, and the decorative yarn is polyester fiber, and the yarn is spun into a yarn by a compound segment color spinning machine, and the yarn is obtained after the standard M color is dyed by using reactive dyes at room temperature.

[0012] Further, in step S2, the color length calculation formula of the segment color yarn is, L cc L is the color length of the segment color yarn, C is the pixel number of the scratch length, L j is the length of the finished fabric, A is the width of the fabric, a wz is the weft shrinkage rate, a wr is the weft dye shrinkage rate.

[0013] Further, in step S2, the color distance calculation formula of the segment color yarn is, L cj L is the color distance of the segment color yarn, P j is the number of warp yarns within 10 cm, L j is the length of the finished fabric, L W is the width of the finished fabric, n is the number of spot position markers, a jz is the preset fabric warp shrinkage rate, a jr is the preset fabric warp dye shrinkage rate, a wz is the weft shrinkage rate, a wr is the weft dye shrinkage rate.

[0014] Further, the calculation formula of L W is, P w P is the number of warp yarns within 10 cm, A is the width of the fabric, and B is the warp length of the fabric.

[0015] Further, in step S2, the color of the scratch is designed according to the need in production, the segment color of the yarn is designed to show color, in order to make the segment color yarn distribute naturally in the fabric, the set color distance can be arranged randomly with fluctuation value, the unit length is controlled in the range of 50% to 150% most naturally.

[0016] The design method of the picture-like jacquard scratch patchy texture feeling fabric provided by the application realizes the development of the scratch patchy texture feeling fabric, and the fabric with exquisite defect style and prominent surface scratch texture effect is prepared.

[0020] In order to make the person in the art better understand the technical solutions in the application, the technical solutions in the embodiments of the application will be described clearly and completely in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments.

[0021] Embodiment 1

[0022] A design method of a picture-like jacquard scratch patchy texture feeling fabric, comprising the following steps:

[0023] (1) The design of the fabric is based on the image of "Lukwang Penison" in Dunhuang murals of Northern Wei Dynasty, which is a traditional culture that consumers are interested in recently. The image is used as the design sample, and the dyed yarn with different colors is used as weft to further enhance the texture effect of the fabric. The "Lukwang Penison" mural is based on the ochre red background, and the mural is affected by natural conditions and human factors, resulting in many scratches on the ochre red background. These scratches form some scattered and uneven natural flaw textures on the picture, and the texture characteristics are rich and obvious. There are many light-colored scratches and spot textures on the fabric. In the design of the color-like landscape pattern, the M-colored weft yarn is used as the different colored yarn, and the distribution of the yarn body is consistent with the distribution of the scratch and flaw texture in the mural.

[0024] First, mark the position of the scratch and spot texture in the selected simulation image, and count it. Take a section of the "Lukwang Penison" mural as an example. The size of the picture is 1545x880 pixels. Use Photoshop software to mark the scratch texture, and select representative spots. The selection should not be missed, and the form of different colored yarn should be considered to represent it as much as possible. The distribution of the spots along the weft direction should be considered. As shown in the attached Figure 1 figure, a total of 106 white scratch texture spots are marked with five-pointed stars, and the randomness of the distribution is more obvious.

[0025] (2) The design and calculation method of the different colored yarn. The color length (or called pitch length) and color distance (or called pitch distance) of the different colored yarn should be determined. The color length of the different colored yarn can be measured directly by measuring the length of the white scratch in pixels, and then calculating the color length on the fabric. According to the design of the fabric product style and the size of the pattern, the length of the finished product L j is designed to be 35 cm (the weft direction of the picture), which is calculated from the regular flower width of the 2520 needle jacquard pattern. The width of the picture on the fabric and the width of the decorative lace on the fabric is a complete flower width of the fabric. The warp and weft density of the fabric P j and P w are 681 / 866 ends / 10 cm respectively. According to experience, the preset warp shrinkage rate a jz is 10%, the weft shrinkage rate a wz is 8%, the preset warp dye shrinkage rate a jr is 0%, and the weft dye shrinkage rate a wr is 8%. The length of the white scratch in the picture (represented by the number of pixels) C varies greatly, ranging from 20 pixels to 200 pixels. Therefore, the length of the weft yarn in the straightened state, i.e. the color length L cc is:

[0026] When the number of pixels of the white scratch length is 20 and 200 respectively, the corresponding color length is calculated as:

[0027] That is, the corresponding color length should be 0.54cm to 5.35cm, and because the color length of the segment color yarn is limited by factors such as fiber length, the color length is generally not less than 2cm, so the intermediate value is taken and a fluctuation range is set, and the design color length is 2 to 3cm.

[0028] Color distance L of segment color yarn cj The number of texture spot markers needs to be deduced in combination with the fabric specifications, and the size calculation method on the straight weft yarn is:

[0029] Wherein L j and L w are the length and width of the finished fabric surface of the picture (corresponding to the weft direction and the warp direction), unit: cm, other parameter meanings are the same as before, and the calculation method of L w is,

[0030] The calculation shows that L w is 15.7cm, which is substituted into the calculation formula of color distance L cj , and the color distance is

[0031]

[0032] That is, the calculation shows that the color distance is about 535.6cm, and because only M yarn is a segment color yarn and the other three color yarns are common yarns in the actual weaving process, that is, the common yarns and the segment color yarns are wefted according to the ratio of 3:1, the color distance is about 535.6 / 4=133.9, and the average color distance is set to be 134cm by taking the integer. In order to avoid regular distribution and make the segment color distribution more natural, the color distance is set to be randomly arranged with a fluctuation range of 70-200cm.

[0033] (3) The production method of the segmental colored yarn, which adopts a composite segmental colored spinning technology, takes cotton fiber as the main material of the fabric base yarn, takes polyester as the segmental colored material, and makes the segmental colored distribution meet the requirements of picture performance. The yarn body is dyed with standard M color by the single dyeing method of active dye, and the segmental colored part is not colored and presents a bamboo joint appearance, realizing the segmental colored effect. In order to improve the fineness, natural texture and wearability of the picture performance of the fabric, the comprehensive linear density of the yarn is determined to be 9.72 terx. The segmental colored yarn is produced on a ring spinning frame, two servo motors are used to control the movements of the middle roller and the rear roller respectively, the middle roller is continuously rotated, and the segmental colored bamboo joint is generated by the intermittent rotation of the rear roller. The segmental colored yarn is prepared into main yarn roving and decorative yarn roving, and 100% Xinjiang fine cotton is used as the main yarn, and 1.4D*38mm polyester staple fiber is used as the decorative yarn. In the basic process of each process, the main yarn and the decorative yarn have the same process as the conventional variety in the processes of scutching, carding and drawing, the cotton fiber is subjected to the process of combing (increasing the processes of pre-drawing, drawing and combing), and the polyester fiber does not need to be subjected to the process of combing because the fiber length is uniform. In the roving process, the main yarn roving has a weight of 5.0g / 10m, the decorative yarn roving has a weight of 4.5g / 10m, and the roving twist factors of the main yarn and the decorative yarn are both 63. In the spinning process, the designed spinning twist is 125.0 twist / 10cm, the designed segmental colored length is 2-3cm, the designed color distance is 70-200cm, and the designed color amount is 0.9. The color amount is the ratio of the rotation speed of the rear roller to the rotation speed of the middle roller. Since only the decorative yarn is subjected to the drafting in the rear zone in the composite segmental colored spinning, the color amount is set as the relative feeding amount of the decorative yarn. In the automatic winding process, the parameters of the electronic yarn clearer are adjusted according to the specifications of the segmental colored bamboo joint to prevent the segmental colored bamboo joint from being cut by mistake.

[0034] (4) In the bleaching and dyeing process design, according to the material characteristics, the segmental colored yarn is mainly made of cotton fiber, and the content of polyester fiber is small, and the color amount is 0.9. It is calculated that the content of polyester in the yarn is 1.6%. In the bleaching and dyeing process, the process of pure cotton yarn is adopted, and the single dyeing of active dye at room temperature is adopted, and the polyester material is not colored.

[0035] (5) Computer pattern design, according to the production method of the picture-like pattern, the design is carried out according to the way of weft color development. First, the color picture is processed and adjusted to the size conforming to the fabric size specification. This time, the picture is adjusted to 2520 pixels in the longitudinal direction and 7040 pixels in the lateral direction. The brightness, contrast, saturation, and edge sharpening processing parameters are adjusted in CMYK mode by Photoshop. The picture is separated into four image files C, M, Y, and K in the "channel separation" mode, and four black and white BMP format pictures are obtained. The four BMP pictures obtained by channel separation are processed by color separation using the pattern top software. The number of gray-scale separations is set according to the required fineness of the picture and comprehensive consideration. The number of color separations for C, M, Y, and K pictures should be consistent, and each is saved for backup. In the pattern software, the pattern is designed by using the color development organization library. Finally, the pattern plate file after process design is converted into JC5 file which can be read by the loom, and saved to the loom for backup.

[0036] (6) Loom weaving, this time the design is carried out by using weft color development. The electronic jacquard equipment matched with 340 type wide-width air-jet loom is used for weaving. The existing weaving beam is used for the warp yarn, which is combed 60s pure cotton yarn. The weft yarn is C, Y, and K three-color 9.72tex pure cotton yarn, and M is segment color segment elastic yarn. The JC5 file processed by pattern design is copied to the computer of the jacquard machine. According to the designed weft insertion order, C, M, Y, and K are arranged in 1#-4# weft accumulator in turn, and the weft insertion ratio is 1:1:1:1. The design of the gray fabric is: width 105 inches, warp density 173 roots / inch, and weft density 220 roots / inch. The main process parameters of the equipment are optimized. The weft insertion air pressure parameters of the four weft accumulators are set first. The optimal process is: the main nozzle weft insertion time is 90-180°, the air pressure is 0.2MPa for the main nozzle and 0.3MPa for the auxiliary nozzle, the loom process parameters are: back beam height position scale is -2, front and back position scale is 5, warp stop motion front and back position scale is 0, height position scale is -1, loom opening time is 300 degrees, and the on-loom tension is 330kgf. The loom is in good condition. After the gray fabric is finished, it is stored in the warehouse after inspection and repair.

[0037] (7) Dyeing and finishing, the picture-like jacquard scratch texture fabric is color woven. The whole production and processing process is: cloth turning → singeing → boiling and bleaching (rolling) → drying → softening → preshrinking → finished product, which can be processed according to the conventional pure cotton production and processing process.

[0038] (8) The final production fabric is shown in the attached Figure 2 picture. It can be seen from the physical picture that the lateral direction has obvious scratch texture.

[0039] Although the present application has been described in detail with reference to the preferred embodiments, it should be understood that the application is not limited to those preferred embodiments. Various modifications and equivalents can be made by those skilled in the art without departing from the spirit and scope of the application. Any and all modifications and equivalents are intended to be included within the scope of the present application.
