Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a method for quickly binding fabric edges based on producing weaving files. Background Art

[0002] Zhuanghua generally refers to a technique used in textile products such as brocade, similar to the craftsmanship of kesi (seamless weaving). The "through warp and weft" technique used in this type of product is not strictly speaking broken weft. Instead, if the weft is not used on the jacquard surface, it is temporarily placed on the woven fabric surface, not cut, and does not participate in interweaving. It is only woven in when it is needed on the front of a specific area. The shuttle is used to weave in this area, so not all wefts are present across the entire width. This method can also be called "digging the shuttle." Our current high-speed jacquard weaves are all through warp and weft. The weft must be hit from the beginning to the end. If the weft is not used on the surface, it floats on the back of the fabric and does not participate in interweaving. After weaving is completed and removed from the loom, the long floating weft threads on the back of the fabric are trimmed off, giving the overall appearance of through warp and weft.

[0003] It's now common to see the removed weft threads, also called "throws," woven over the ground fabric to accentuate the fabric's rich, three-dimensional effect. This refers to the "stop-weave" technique, where a piece of fabric is woven with a localized weft repetition to create a patterned effect. Typically, these repetitions (the "stop-weave" area) create a fuller pattern. Most stop-weave fabrics are called "throws," and there are no color restrictions. A single layer with stop-weave is called "throws," while a double weft with stop-weave is called "double weft with throws." Throws can also be strictly distinguished from the ground weft, creating multiple layers of weft throws. In addition to the surface color, the backing weft of "throws" is not interwoven, leaving it floating. This is then removed manually or by shearing. Unlike the "cut-weft" weaving technique used for warp-through and weft-break embellishment, this weft is not cut in a specific area, but rather by the left-right shuttle. The weft threads cut off in the jacquard shear products of modern machines are suspended on the back of the fabric. If they are not fixed, they are very easy to be pulled out and fall off, which requires a hemming reinforcement design.

[0004] Currently, for the design of multi-layered jacquard shear-cut fabrics with continuous warp and broken weft, if there is only one type of thrown weft, the simplest method is to perform overall hemming of the jacquard pattern area. If there are multiple thrown wefts, in addition to overall hemming of the jacquard pattern area, separate hemming can also be performed on different areas of the jacquard pattern. However, both the first overall hemming method and the second individual hemming method require technical color separation of the original pattern, and each has its own advantages and disadvantages. The second method, while more effective, becomes quite complex when the number of thrown wefts is large, especially requiring extensive and detailed color separation before the fabric is laid. Therefore, it is essential to develop a technological innovation that can accurately and quickly reinforce the hemming of the original pattern without changing the initial pattern vector color block.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] In order to solve the technical problems existing in the above-mentioned prior art, the present invention provides a method for quickly binding fabric edges based on the production of weaving files.

[0007] To achieve the above object, the present invention adopts the following technical solution: a method for quickly binding fabric edges based on producing woven files, comprising the following steps:

[0008] (1) Flip the initial color block pattern horizontally without adding color blocks, build a shuttle, and set the number of shuttles according to the color requirements of the pattern color block;

[0009] (2) organizing and laying out the pattern;

[0010] (3) Use weaving design CAD software to find the long floating threads that need to be cut off;

[0011] (4) The jacquard weft yarns that float on the ground and need to be cut off are hemmed;

[0012] (5) Setting the shuttle parameters for the weaving file that has been processed by the hemming process, setting it into a shuttle, and laying the lock-edge structure for the warp, weft and hemming color blocks respectively;

[0013] (6) Adjust the production weaving file and completely swap the warp and weft starting methods in the file to form a reverse weaving file.

[0014] The initial color blocks of the pattern in step (1) include color blocks A, B, C and D; wherein the color block A of the flower part is represented by color No. 5, the color block B of the flower part is represented by color No. 122, the color block C of the flower part is represented by color No. 8, and the color block D of the ground part is represented by color No. 38.

[0015] The specific steps of constructing the shuttle are as follows: color No. 38 corresponds to the first shuttle, and the first shuttle is used for the regular weft; color No. 5, color No. 122 and color No. 8 correspond to the second, third and fourth shuttles respectively, and finally the stop winding function is set, and the three color shuttle jacquards are superimposed on the fabric surface of the regular weft.

[0016] The specific steps of step (2) include: laying the processed pattern into a weaving file with color No. 1 as the warp and color No. 12 as the weft.

[0017] The specific steps of step (3) include: finding the long floating thread floating on the back of the fabric, that is, finding the long floating thread of color 1 of the warp tissue from the back of the tissue, and marking it with color 5.

[0018] The specific steps of step (4) include: wrapping 10 stitches on both sides of the No. 12 color of the jacquard weft structure of the flower part to the No. 5 color of the floating long thread directly in contact with it, and marking it with No. 28 color.

[0019] The specific steps of step (5) include: taking the No. 12 color of the jacquard weft structure of the flower part as the base point, wrapping 10 stitches toward the No. 5 long floating thread connected to it.

[0020] The specific steps of step (5) also include: generating a weaving file for the initial color block pattern and checking the long edge, then re-laying the secondary structure. At this time, the shuttle parameter is reset to 1 weft thread, and one weft multi-point structure is laid for each color block.

[0021] The specific steps of step (5) also include: the warp No. 1 color in the generated weaving file is still laid with a full warp structure; the weft No. 12 color is still laid with a full weft structure; the hemming No. 28 color is laid with a plain weave; the long float No. 5 color, except for being laid with a plain weave, all other warp structures are No. 1 color, and the long floats floating on the back of the fabric are waiting to be cut off after weaving; the designed preset structure effect is laid, and finally the warp and weft structure of the entire weaving file are completely reversed to obtain a ready-made reverse weaving file.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) This application makes technical innovations in the design process of hemming reinforcement, which realizes that the initial pattern vector color block is not changed. On the basis of using the weaving design CAD software to quickly produce weaving files, the hemming reinforcement of the scissor-cut weft yarn similar to the style of the embroidery shuttle product is carried out quickly, thereby realizing the efficient design of complex jacquard scissor-cut fabrics with continuous warp and broken weft;

[0024] (2) The present application innovates the rapid hemming method of continuous warp and broken weft multi-weft jacquard sheared fabrics, and the design is very fast and simple with a low error rate. It does not require any color block processing or addition to the initial pattern, and only needs to be laid out in the original state of the pattern, so even complex patterns are not easily missed or wrong. It avoids the overlapping waste of weft threads in the jacquard area of ​​the flower part. At the same time, it improves the overall hemming so that all weft threads overlap in the hemming area, and the hemming tissue is tight, which causes the weaving warp threads to be tightened, resulting in weaving problems such as warp breakage.

[0053] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0054] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are referring to the position state of the figure being described. The purpose is to facilitate public understanding, and therefore it cannot be understood as a special limitation on the technical solution provided by the present invention.

[0055] like Figure 1 As shown, a method for quickly binding fabric edges based on producing weaving files comprises the following steps:

[0056] (1) Horizontally flip the initial color block pattern (such as Figure 2 As shown), there is no need to add color blocks, build the shuttle, and set the number of shuttles according to the requirements of the color block of the pattern (the overall shuttle process is as follows Figure 3 shown);

[0057] Among them, the initial color block pattern includes color block A, color block B, color block C and color block D; the color block A of the flower part is represented by color No. 5, the color block B of the flower part is represented by color No. 122, the color block C of the flower part is represented by color No. 8, and the color block D of the ground part is represented by color No. 38; there is no need to process any vector color blocks during design, just a simple horizontal flip of the pattern is required, and the design can be carried out directly according to the organizational requirements of the cut flower.

[0058] The specific steps of constructing the shuttle are as follows: Figure 3 As shown, the ground color No. 38 corresponds to the first shuttle (normal weaving), and the first shuttle is used for the normal weft; the flower color No. 5, the flower color No. 122 and the flower color No. 8 correspond to the second, third and fourth shuttles (throwing shuttles) respectively, and finally the stop-winding function is set. The stop-winding function is represented by color No. 68, and a stop-winding relationship is formed with the ground part in which the ground part uses one shuttle rear shaft to let the warp, and the three shuttles of the flower part stop letting the warp with one shuttle rear shaft respectively, and the three flower color number throwing shuttle jacquards are superimposed on the cloth surface of the normal weft WD; the shuttle picking order corresponding to the pattern vector color blocks of the ground and flower parts is as follows Figure 4-11 shown.

[0059] (2) Directly lay the pattern (one-time laying);

[0060] like Figure 12 As shown, the production weaving file is generated according to the general weave laying method, and the processed pattern is laid into a weaving file with color 1 as the warp and color 12 as the weft. For details, see Figure 13 and Figure 14 The weft WD is interwoven with the warp in both the ground and flower parts, and the wefts WA, WB, and WC are only interwoven in the Figure 2 Color blocks A, B, and C in the weft are weaved with 8 satin wefts. In areas A, B, and C, aside from the WD weft in the ground portion and its corresponding WA, WB, and WC wefts, the other two wefts are placed at the back of the fabric, uninterwoven with the warp threads, and float on the back, awaiting weaving. For example, in area A, the WA weft is weaved with 8 satin wefts on the surface, while the WD weft is used as a plain weave lining on the back. The WB and WC wefts are not interwoven with the warp threads in this area, and float at the back, awaiting weaving completion and weaving.

[0061] (3) Use weaving design CAD software to find the long floating length of the weft that needs to be trimmed;

[0062] First, if Figure 15 As shown, first find the long floating line behind the fabric. The details are as follows Figure 16 As shown, find the long float of color 1 from the back of the weave. Because the weave of the jacquard pattern on the front side uses 8 wefts and the floating point of the weft is 7 needles, find the float that is longer than the 7-needle pattern needle and mark it with color 5. The float found is as follows Figure 14As shown on the right, details of some areas are as follows Figure 17 shown.

[0063] (4) The jacquard weft yarns that float on the ground and need to be cut off are hemmed (such as Figure 18 shown);

[0064] Specific details such as Figure 19 and 20 As shown, find the floating thread on the back of the fabric that is longer than 7 stitches and mark it with color No. 5 (green). Color No. 5 must be connected to the weft starting point of the flower part (color No. 12).

[0065] Details such as Figure 18 As shown, in the weaving design CAD software, the jacquard weft fabric of the floral part is set to be wrapped with 10 stitches on both sides of the directly contacted floating long line of color 5 in color, and marked with color 28 (blue).

[0066] The overall effect is as follows Figure 21 As shown in the figure, the bright part is the edging area of ​​the jacquard wefts WA, WB and WC. Due to the use of weaving files for fast and convenient edging, the three wefts do not interfere with the other two wefts except for their own jacquard areas, and the edging is very clear and neat (details such as Figure 22 (shown as a medium blue block).

[0067] (5) Laying the edge of the color block (secondary laying);

[0068] like Figure 22 As shown, take the No. 12 color of the jacquard weft structure of the flower part as the base point, and wrap 10 stitches toward the long floating line No. 5 connected to it (indicated by the blue No. 28 color).

[0069] In order to prevent the jacquard weft yarn from sliding and snagging easily after being cut off from the ground long floating line, it is necessary to lay the tightest plain weave on the No. 5 hemming color block to form a tight support with the ground weft yarn WD. Figure 23 The figure shows the interface after the weaving file is hemmed. At this time, the weaving file is generated for the initial color block pattern and the long hemming is checked and the secondary weave is laid again. At this time, the shuttle parameters are reset to 1 weft, and one weft multi-point weave is laid for each color block. The operation is very simple.

[0070] Furthermore, if Figure 23 As shown in the generated weaving file, the warp color No. 1 is still laid with full warp weave; the weft color No. 12 is still laid with full weft weave; the hemming color No. 28 is laid with plain weave (as shown in the figure). Figure 24 As shown); long float No. 5 color is laid into the full warp No. 1 color, floated on the back of the fabric, and waited for weaving to be completed and cut off (as shown Figure 25 After the tissue is laid, Figure 26 As shown. The preset organizational effect is organized and laid out, and the final effect is as follows Figure 27 shown.

[0071] (6) Adjust the production weaving file, and finally completely swap the warp and weft organization of the entire weaving file to create a ready-made reverse weaving file, such as Figure 28 As shown, it is convenient for the machine operator to operate.

[0072] The present application makes technical innovations in the design process method of edge reinforcement, so as to achieve the goal of not changing the initial pattern vector color block, and using the pattern design CAD software to quickly produce weaving files (the weaving files can include ep, jc5, bmp and other formats), to quickly edge reinforce the sheared weft threads similar to the style of the embellished shuttle product, thereby realizing the efficient design of complex jacquard sheared fabrics with continuous warp and broken weft; by innovating the rapid edge-binding method for continuous warp and broken weft multiple weft jacquard sheared fabrics, the design is very fast and simple, with a low error rate; and there is no need to process or add any color blocks to the initial pattern, only to lay the pattern in its original state, so that even complex patterns are not easily missed or wrong; the overlapping waste of weft threads in the jacquard area of ​​the flower part is avoided; at the same time, the overall edge is improved, all weft threads are concentratedly overlapped in the edge area, and the edge organization is tight, which causes the weaving warp threads to be tightened, causing weaving problems such as broken warp.

[0073] The above content is a further detailed description of the technical solution provided in combination with the preferred implementation methods of this patent. It cannot be determined that the specific implementation of the present invention is limited to the above descriptions. For ordinary technicians in the technical field to which this patent belongs, they can make several simple deductions or replacements without departing from the concept of this patent, which should be deemed to fall within the scope of protection of this patent.
