Description

Technical Field

[0001] The present invention relates to the field of textile technology, and in particular, to a jacquard lace jacquard fabric with a saving jacquard comb and a manufacturing method thereof. Background Art

[0002] When using a jacquard comb for jacquard of existing fabrics, it is necessary to thread all the corresponding needle positions with yarns and then perform jacquard weaving. The number of threading needle positions is the number of needle positions spanned by the jacquard pattern contour. Whether the needle position is used for jacquard weaving or empty needle weaving, the jacquard comb needs to hang yarns. This will cause waste of yarn raw materials and cumbersome work of hanging yarns.

[0003] However, by using a jacquard comb for jacquard and cooperating with reasonable process design, precise pattern design and the use of functional yarns, the yarn raw materials can be greatly saved on the premise of ensuring product stability and output, and 99% of yarn waste can be saved. It not only expands the selection space of pattern design, enriches the pattern tissue effect, improves the added value of the product, but also reduces the production cost of the shoe upper fabric. Summary of the Invention

[0004] In order to solve the problems existing in the above-mentioned traditional monofilament fabric mesh shoe upper, the present invention provides a jacquard lace jacquard fabric with a saving jacquard comb.

[0005] The present invention discloses a jacquard lace jacquard fabric with comb savings, including a fabric body integrally woven by a warp knitting machine. The fabric body is woven by a pattern comb, a jacquard and a ground comb. The fabric body further includes a bottom cloth and a jacquard pattern. The jacquard pattern has a pattern outline. According to the stitch pitch of the pattern outline of the jacquard pattern on the fabric body, the number of bars of the pattern comb is determined. The jacquard pattern area on the fabric body is woven after the pattern comb is threaded with yarn. The ground comb is threaded with yarn and then weaves the bottom cloth on the fabric body. The horizontal lateral movement distance of the pattern comb is 180 needle positions. The pattern comb performs jacquard weaving within 180 needle positions in the horizontal lateral direction of the fabric body. According to the pattern outline of the jacquard pattern of the fabric body, the number of yarns hung on the pattern comb bars is at least the maximum intersection number of the starting point of the pattern outline at the fabric edge. The maximum intersection number at the starting point of the edge is determined by making several longitudinal auxiliary lines through the fabric edge outline and several horizontal auxiliary lines through the pattern outline for virtual intersection. Within the horizontal range of 180 stitches of the pattern outline on the fabric body, if the pattern outline is a continuous pattern, continuous weaving is performed. If a broken pattern is encountered, empty needle weaving is performed during the weaving process at this weaving position. If there is no overlap during the virtual translation between broken patterns, there is no need to increase the number of pattern comb bars. If there is overlap during the virtual translation between broken patterns, the number of pattern comb bars needs to be increased. During the weaving process of the fabric body, if there are multiple starting weaving paths within the same weaving range, the corresponding number of yarns hung on the pattern comb needs to be determined according to the number of weaving paths for weaving. If multiple weaving paths finally converge to one weaving path, the hanging yarn needles corresponding to this pattern comb continue to weave, and the hanging yarn needles without a weaving unit perform empty needle weaving. If it finally becomes multiple weaving paths again, weaving is performed according to the number of hanging yarn needles corresponding to the number of paths. A slide rail is provided on the pattern comb, and 1 grain of yarn is hung on each slide rail.

[0006] The present invention also provides a manufacturing method of the jacquard lace jacquard fabric with comb savings as described above, including a jacquard part, a connecting part and a bottom base part. The jacquard part has a pattern comb jacquard part and a jacquard jacquard part, and includes the following steps:

[0007] S1. Comb bar setting: Select a machine for weaving. The machine has at least 8 comb bars. The 8 comb bars are sequentially set as pattern comb bar PB1, pattern comb bar PB2, jacquard comb bar JK3.1, jacquard comb bar JK3.2, ground comb bar GB4, ground comb bar GB5, ground comb bar GB6, and ground comb bar GB7 from the front needle bed to the rear needle bed;

[0008] S2. Warping; The pattern comb bars PB1, PB2, jacquard comb bars JK3.1, JK3.2, ground comb bars GB4, GB5, GB6, and GB7 are warped with one or more combinations of nylon, CD, polyester, spandex, TPU, TPEE, reflective yarn, mildew-proof and antibacterial yarn, photosensitive yarn, and digital transfer yarn;

[0009] S3. Warping: The pattern combs PB1 and PB2 are warped on the machine in an empty warping manner. The Jacquard combs JK3.1 and JK3.2 are warped on the machine in a 1-through-1-empty manner. The ground combs GB4 and GB5 are warped on the machine in a full warping manner. The ground combs GB6 and GB7 are warped on the machine in a 1-through-1-empty manner.

[0010] S4. Knitting: The pattern combs PB1 and PB2 lay yarns on the front needle bed and / or the rear needle bed to form the pattern jacquard part. The Jacquard combs JK3.1, JK3.2, and the ground comb GB4 lay yarns on the front needle bed and / or the rear needle bed to form the Jacquard jacquard part. The ground comb GB5 forms the connecting part on the front needle bed and / or the rear needle bed. The ground combs GB6 and GB7 lay yarns on the rear needle bed to form the bottom base part.

[0011] S5. Weaving: The pattern combs PB1 and PB2 both run a changing weft insertion type of fabric structure or a changing loop formation type of fabric structure. The Jacquard combs JK3.1 and JK3.2 both run the basic Jacquard fabric structure. The ground combs GB4, GB5, GB6, and GB7 all run the basic warp knitting fabric structure.

[0012] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0013] The warp knitted sandwich mesh fabric knitted by the currently equipped warp knitting machine with pattern combs, through reasonable process design of the pattern combs and the Jacquard jacquard area, makes full use of the unique properties of functional yarns and the unique advantages of the warp knitting machine, combined with the change of empty warping of the combs, as well as the precise design of the pattern and the coordinated use of chemical fiber yarns, produces a high-performance sandwich Jacquard lace jacquard fabric with a unique appearance texture.

[0014] For this Jacquard lace jacquard fabric, the pattern jacquard part only supplies yarn to the pattern combs participating in knitting, which can greatly save yarn raw materials on the premise of ensuring product stability and output, and can save 99% of yarn waste. It not only expands the selection space of pattern design, enriches the pattern fabric effect, improves the added value of the product, but also reduces the production cost of the shoe upper fabric.

[0028] The following will combine the drawings and embodiments to detail the implementation manners of the present invention, so as to fully understand how the present invention uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly. It should be noted that as long as there is no conflict, each embodiment in the present invention and each feature in each embodiment can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0029] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without these specific details or in the specific manners described herein.

[0030] Embodiment 1

The jacquard pattern has a flower shape contour. The jacquard pattern area on the fabric body is woven after the comb is threaded with yarn, and the ground comb is threaded with yarn and then the base fabric is woven on the fabric body.

[0032] Determine the number of bars of the comb according to the pattern contour of the jacquard pattern on the fabric body.

[0033] According to the flower shape contour of the jacquard pattern of the fabric body, determine that the number of bars of the comb is at least the number of intersection points of the flower shape contour at the fabric edge.

[0034] The horizontal traverse distance of the comb is 180 needle positions, and the comb weaves within 180 needle positions in the horizontal direction of the fabric body.

[0035] The number of intersection points at the edge is: make several vertical auxiliary lines on the fabric edge contour and several horizontal auxiliary lines on the flower shape contour, and then find the intersection points.

[0036] Within the horizontal range of 180 needles of the flower shape contour on the fabric body, if the pattern within the flower shape contour is a continuous pattern, continuous weaving is carried out; if a broken pattern is encountered, the knitting at this position is carried out with empty needles during the weaving process.

[0037] During the weaving process of the fabric body, if there are multiple starting weaving paths within the same weaving range (with 180 needle positions as a base), it is necessary to determine the corresponding number of comb bars according to the number of weaving paths for weaving. If multiple weaving paths finally converge to one weaving path, one of the combs continues to weave, and the other combs carry out empty needle weaving. If it finally becomes multiple weaving paths again, the number of combs corresponding to the number of paths is used for weaving.

[0059] Example 2

[0060] Such as Figure 2As shown, the jacquard pattern of the fabric is a striped pattern and is symmetrical on the left and right. The overall fabric has more than 180 needle positions. The distance measurement of the stripes of the single side pattern meets the 180 needle length. The horizontal horizontal span of the woven patterns on both sides exceeds 180 needle positions. It can be determined that at least two combs are needed for jacquard weaving. The stripes of the single side pattern can be seen to start with four lines at the bottom and three lines at the top. The maximum number of intersections between the pattern and the edge is four. To weave the single-sided stripes, a comb with at least four grains of yarn is required. The four lines in the pattern can be divided into the first, second, third and fourth hanging yarn needles, respectively. Among them, the first, third and fourth are empty-thread continuous weaving. After the second needle is weaved to the intersection with the first needle, empty-needle continuous weaving is performed.

[0061] Example 3

[0062] like Figures 3-5 As shown, the fabric has a striped pattern, but is asymmetrical. The overall fabric has more than 180 stitches, but the stripes on one side are within 180 stitches. Therefore, it can be determined that at least two pattern combs are needed for jacquard weaving. The method for determining the minimum number of yarns required for each pattern comb is as follows:

[0063] If the weaving pattern on the single side is in the shape of an "A", then a horizontal dividing line is drawn on the "A" shape to determine two intersection points, and two yarns need to be hung on each comb;

[0064] If the weaving pattern on the single side is in the shape of a Chinese character "川", then a horizontal dividing line is drawn on the Chinese character "川", which can be determined as three intersection points, and three yarns need to be hung on each comb;

[0065] If the weaving pattern on the single side is in the shape of an "N", then the "N" shape is divided horizontally, and three intersection points can be determined, and each comb needs to hang three grains of yarn;

[0066] If the weaving pattern on the single side is in the shape of a "W", then the "W" shape is divided horizontally, and four intersection points can be determined, and each comb needs to hang four grains of yarn;

[0067] If the weaving pattern on the single side is in the shape of a "∑" character, a horizontal dividing line is drawn on the "∑" character to determine an intersection, and each comb needs to hang a yarn;

[0068] As mentioned above, after determining the number of pattern combs and bars, the number of hanging yarns on each comb bar is determined by the maximum number of intersections of the horizontal and horizontal outlines of the pattern relative to the vertical intersection of the fabric edge. If the entire fabric consists of two pattern patterns, the required number of hanging yarns can be the superposition of the number of hanging yarns similar to ① to ⑤. For example, if the pattern on the left is "A" shaped and the right is "N" shaped, two pattern combs and bars are required, one pattern comb for hanging two yarns and the other pattern comb for hanging three yarns.

[0069] Example 4

[0070] like Figure 6 As shown, the fabric weaving pattern is a striped pattern. When there are two patterns, the overall knitted fabric exceeds 180 needle positions. The two patterns intersect, but the overall needle distance is greater than 180 needle positions, which exceeds the horizontal lateral movement distance of a single pattern comb. Therefore, it can be determined that at least two pattern combs are needed for jacquard weaving. The method for determining the minimum number of yarns required for each pattern comb is as follows:

[0071] For example, if the weaving pattern is in the shape of "AW", where the left side of the "A" is within the 180-needle spacing, the half "V" of the "W" on the other side is within the 180-needle spacing of the left pattern comb, and the other half of the "V" is within the weaving range of the right pattern comb, a horizontal dividing line is drawn, and it can be determined that there are 6 intersections in the horizontal direction of "AW". In this case, a total of six yarns need to be hung for weaving. In more cases, four yarns are hung on the left pattern comb and two yarns are hung on the right pattern comb.

[0072] Example 5

[0073] like Figure 7 As shown, the fabric weaving pattern is a striped pattern, the overall knitted fabric has more than 180 stitches, the maximum stitch distance between individual patterns is less than 180 stitches, and the horizontal lateral movement distance of a single pattern comb is sufficient. Therefore, it can be determined that at least one pattern comb is required for jacquard weaving. The method for determining the minimum number of yarns required for each pattern comb is as follows:

[0074] If the weaving pattern is in the shape of "AW", and a dividing line is drawn horizontally, it can be determined that there are 6 intersections in the horizontal direction of "AW", so a total of six yarns need to be hung for weaving;

[0075] If the weaving pattern is in the shape of "AWM", and a dividing line is drawn horizontally, it can be determined that there are 10 intersections in the horizontal direction of "AWM", so a total of ten yarns need to be hung for weaving;

[0076] If the weaving pattern is in the shape of "WWMM", and a dividing line is drawn horizontally, it can be determined that "WWMM" has 16 intersections in the horizontal direction, so a total of 16 yarns need to be hung for weaving;

[0077] In order to avoid the needle collision in the weaving track in the above weaving, odd and even needles are mostly used when hanging the yarn. As shown in Figure 1, the "W" shape requires four yarns to be hung, and the order of hanging the yarn is one, three, two, and four.

[0078] Example 6

[0079] like Figure 9 As shown, the difference between this embodiment and embodiments 1-5 is that the jacquard patterns of the above embodiments 1-5 are arranged in a single layer in the horizontal direction and are not restricted in the vertical position, while the jacquard patterns of this embodiment are arranged in multiple layers in the horizontal direction and are not restricted in the vertical position;

[0080] If the knitting pattern is arranged in a double horizontal pattern, with the first horizontal arrangement being "AWM" and the second arrangement being "WMA", a horizontal dividing line can be used to determine that there are 10 intersection points, so a total of ten yarns need to be hung:

[0081] If this double arrangement is within 180 needle positions, only one jacquard comb is required for knitting jacquard;

[0082] If this double arrangement exceeds 180 needle positions, an additional jacquard comb is needed for knitting jacquard.

[0083] Embodiment 7

[0084] As Figure 8 shown, the difference between this embodiment and Example 6 is that if the jacquard pattern is a misaligned superimposed pattern, as shown in a certain figure, the maximum number of intersection points obtained by horizontal horizontal division is the minimum number of yarns to be hung. The number of yarns that can be hung on each jacquard comb is determined by the number of tracks of the jacquard comb. For example, within the original 180 needle pitch range, one jacquard comb is required for knitting jacquard, but if the number of yarns to be hung within the range exceeds the limit number of yarns that can be hung on the original jacquard comb, an additional jacquard comb needs to be added to cooperate in knitting jacquard, and so on.

[0085] Embodiment 8

[0086] The difference between this embodiment and Embodiment 7 is that if the jacquard pattern is an overlapping pattern (pattern within a pattern / object on an object), the maximum number of intersection points of the upper and lower layer patterns needs to be confirmed separately. Within the 180 needle position range, for each additional layer of three-dimensional upward stacking, an additional jacquard comb is required;

[0087] On this basis, if the span of the jacquard pattern also exceeds 180 needle positions while the number of three-dimensional upward stacking layers increases, it is necessary to separately confirm within the same knitting range:

[0088] 1. For a knitted fabric, there are jacquard patterns on both the left and right sides, and the distance between the patterns exceeds 180 needle positions:

[0089] If the left knitted pattern is a double-layer pattern and the right pattern is a single-layer pattern, then in terms of the number of stacking layers, at least three jacquard combs are required.

[0090] The above Embodiments 1-8 take 180 needle positions as an example for the maximum horizontal movement knitting of the jacquard comb, but the actual needle pitch is determined by the maximum needle pitch of the jacquard comb comb, but the principle is the same, and the change of the actual needle pitch is not limited to this.

[0091] The above has schematically described the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by this and, without departing from the gist of the present invention, creatively design structural manners and embodiments similar to this technical solution, they shall fall within the protection scope of the present invention.
