Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile manufacturing, in particular to a pre-positioning cutting piece production method for solving the protrusion and pattern misalignment of embroidery lace seams. BACKGROUND

[0002] Embroidery is a traditional handicraft of decorating patterns on fabrics with needle and thread, and its core is to use embroidery needle to guide the thread and stitch the needle according to the design pattern on the textile, forming patterns or characters, which has both practical and artistic value. Its history can be traced back to the ancient times, and it was initially used for self-decoration, such as tattooing and painting clothes. Later, it developed into embroidery on fabrics, and there were official records in the Zhou Dynasty. It was spread through the Silk Road in the Han Dynasty, combined with Buddhist art in the Tang Dynasty, integrated into the style of painting and calligraphy in the Song Dynasty, and formed regional schools in the Ming and Qing Dynasties. In modern times, it is combined with technology and fashion, such as AI design and digital production. In terms of techniques, embroidery covers dozens of needle methods such as wrong needle embroidery, random needle embroidery, net embroidery, and full-area embroidery. The four famous embroideries (Suzhou, Hunan, Sichuan, and Guangdong) each have their own characteristics: Suzhou embroidery is known for its fine and elegant style, Hunan embroidery excels in representing three-dimensional forms, Sichuan embroidery has rich needle methods, and Guangdong embroidery has bright colors. In terms of materials and tools, embroidery needles, embroidery threads (such as silk threads and wool threads), embroidery fabrics (such as silk and cotton), and embroidery frames are mainly used, supplemented by scissors, water-based pens, and copy paper. Embroidery is not only an important carrier of cultural heritage, but also reflects the aesthetic interest and wisdom of the Chinese nation. It also has economic value (promoting the development of the industrial chain), social value (enhancing cultural identity), and international exchange value (showcasing Chinese culture), and is hailed as the "Oriental Art Treasure" of "using needle as pen and thread as ink".

[0003] In the existing embroidery garment manufacturing technology, the commonly used method is to continuously embroider the designed pattern on a large piece of fabric to form a continuous pattern fabric. Before sewing onto the garment, the fabric with continuous patterns needs to be folded multiple times according to the shape and size of the garment cutting piece, and then cut on the folded multiple layers to cut out multiple cutting pieces at one time.

[0004] However, this method has significant defects: first, multiple folding will cause the pattern in the folded area to be distorted, deformed, or cut off, making the pattern on the edge of each cut pattern fabric incomplete. Second, when these pattern-incomplete cutting pieces are sewn onto the garment, especially when two cutting pieces need to be spliced at the seam, it is difficult to achieve accurate alignment of the patterns on both sides of the seam due to the damage to the pattern during cutting, resulting in obvious pattern misalignment, interruption, or visual discontinuity, which seriously affects the appearance and product quality of the garment. In addition, the accumulation of multiple layers of fabric and embroidery thread at the seam also easily causes the part to protrude, affecting the comfort and flatness of the garment. SUMMARY

[0005] The purpose of this invention is to provide a pre-positioning cut piece production method to solve the problem of raised seams and misaligned patterns in embroidered lace. This method addresses the shortcomings of existing technologies where patterns are damaged during cutting, making it difficult to achieve precise alignment of patterns on both sides of the seam. This results in obvious pattern misalignment, interruption, or visual discontinuity, which seriously affects the aesthetics and quality of the garment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for producing pre-positioned cut pieces to solve the problem of misalignment between the seam protrusions and the floral pattern in embroidered lace, comprising the following steps:

[0007] S1. Create a cutting template based on the final shape of the garment pieces;

[0008] S2. On the base fabric, arrange the layout according to the cutting template and set gaps between adjacent template outlines;

[0009] S3. According to the layout, embroider independent and complete floral patterns on the base fabric corresponding to the area inside the outline of each template.

[0010] S4. Cut out the pieces with complete floral patterns one by one along the outline of each template.

[0011] Furthermore, the width of the gap described in S2 is 3 mm to 10 mm.

[0012] Furthermore, the layout in S2 is completed by CNC layout software. The outline data of the cutting template is input into the software, and the software automatically optimizes the layout and marks the gaps.

[0013] Furthermore, in S3, a CNC embroidery machine is used for embroidery, which performs embroidery based on a pre-stored independent pattern file that matches the internal area of ​​each template outline.

[0014] Furthermore, before embroidery, positioning marks are formed on the base fabric to locate the outline of the template; during embroidery, the CNC embroidery machine accurately determines the embroidery position of each floral pattern by recognizing the positioning marks.

[0015] Furthermore, in step S4, a laser cutting device is used for cutting, and the laser cutting path coincides with the outline of the template.

[0016] Furthermore, the laser cutting equipment also performs laser edge locking on the edges of the cut pieces to prevent the fabric from fraying.

[0017] Furthermore, the cutting template is made of a transparent material, on which the outline of the cut pieces and the design baseline for aligning the pattern are drawn.

[0018] Compared with existing technologies, the pre-positioning pattern production method provided by this invention, which solves the problems of raised seams and misaligned patterns in embroidered lace, ensures that the embroidered pattern on each pattern piece is completed as an independent unit before cutting by first positioning, then embroidering, and finally cutting independently. This fundamentally avoids the pattern being cut, twisted, or deformed due to multi-layer folding and cutting, guaranteeing the absolute integrity and visual consistency of each pattern unit. Secondly, because the edge pattern of each pattern piece is complete and clear, it provides an irreplaceable and precise alignment benchmark for the sewing process. Operators can easily and seamlessly connect the patterns on both sides of the seam, completely eliminating the unavoidable misalignment, interruption, and visual discontinuity of patterns in traditional methods, greatly improving the aesthetics and quality of the garment. Furthermore, the independent single... The layered cutting method fundamentally eliminates the accumulation of multiple layers of embroidery thread and fabric at the seams, significantly reducing the physical thickness and protrusion of the seams, making the seams of the garments smooth and flat, and significantly improving wearing comfort and the overall silhouette of the clothing. In addition, the method of this invention is naturally compatible with digital production processes. The digital template, automatic software layout, CNC embroidery and precision cutting can be efficiently integrated to achieve high-precision and highly repeatable automated production. This not only greatly improves production efficiency and scale capacity, but also ensures a high degree of product consistency. At the same time, by avoiding defects and losses caused by folding and cutting, the yield rate is significantly improved, and the overall production cost can be optimized and controlled, providing a reliable technical path for high-quality and large-scale manufacturing of embroidered garments. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this invention. For those skilled in the art, other drawings can be obtained based on these drawings.

[0020] Figure 1 This is a flowchart illustrating the preparation process of a pre-positioned cut piece production method for resolving the misalignment of embroidered lace seam protrusions and floral patterns, as provided in an embodiment of the present invention. Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Please see Figure 1 A pre-positioning pattern production method to solve the problem of embroidered lace seam protrusions and pattern misalignment includes the following steps:

[0024] S1. Create a cutting template based on the final shape of the garment pieces;

[0025] S2. On the base fabric, lay out the pattern according to the cutting template and set gaps between adjacent template outlines.

[0026] S3. Based on the layout, embroider independent and complete floral patterns on the base fabric corresponding to the area inside the outline of each template.

[0027] S4. Cut out each piece with the complete floral pattern one by one along the outline of each template.

[0028] The width of the gap in S2 is 3mm to 10mm.

[0029] The layout in S2 is completed by CNC layout software. The outline data of the cutting template is input into the software, which automatically optimizes the layout and marks the gaps.

[0030] In S3, a CNC embroidery machine is used for embroidery. The CNC embroidery machine performs embroidery based on a pre-stored independent pattern file that matches the internal area of ​​each template outline.

[0031] Before embroidery, positioning marks are formed on the base fabric to locate the outline of the template; during embroidery, the CNC embroidery machine accurately determines the embroidery position of each floral pattern by recognizing the positioning marks.

[0032] In S4, laser cutting equipment is used for cutting, and the laser cutting path coincides with the outline of the template.

[0033] The laser cutting equipment also performs laser edge locking on the edges of the cut pieces to prevent the fabric from fraying.

[0034] The cutting template is made of transparent material, on which the outline of the cut pieces and the design baseline for aligning the pattern are drawn.

[0035] First, a rigid template is made according to the shape of the cut pieces of the target garment. Then, the pattern is manually laid out on a large-format base fabric according to the template, ensuring that there is a 5mm gap between adjacent outlines and marking them with chalk. Next, the operators independently embroider a complete unit pattern within each marked outline. Finally, scissors are used to strictly cut along the marked lines one by one to obtain ten complete patterned pieces with clear edges. After sewing, the pattern at the seam is accurately aligned without any misalignment.

[0036] Example 2:

[0037] This embodiment provides a technical solution based on Embodiment 1: After digitizing the shape of the cut piece, it is imported into CNC layout software, which automatically lays out the material on a virtual base fabric with a width of 140cm and generates an optimized scheme with a 4mm process gap; the CNC embroidery machine receives the file and accurately embroiders an independent and complete pattern at the corresponding coordinate position on the base fabric; after completion, it is transferred to a laser cutting platform, where the laser strictly cuts according to the digital outline and simultaneously melts and seals the edges, realizing fully automated high-precision production and greatly improving efficiency and consistency.

[0038] Example 3:

[0039] Using water-soluble nonwoven fabric as the base, after CNC layout and embroidery, individual pieces are precisely cut along the contour using a CNC vibrating knife; then the pieces are placed in 40℃ warm water and stirred to dissolve the base fabric, resulting in pure embroidered thread hollow lace without a backing support, perfectly maintaining the integrity of complex patterns and the smoothness of the edges, completely avoiding the problem of broken threads and damage in traditional methods.

[0040] Example 4:

[0041] Using a transparent acrylic template engraved with the outline of the cut pieces and cross-shaped positioning marks, the positioning marks are imprinted on the base fabric; the CNC embroidery machine is equipped with a vision recognition system to first capture the marks for precise positioning, and then embroider within the area; after cutting, ironing makes the marks disappear, ensuring that the relationship between the pattern and the cut edge is absolutely accurate, providing a solid foundation for perfect alignment during sewing.

[0042] Comparative Example 1:

[0043] Using the same design, continuous embroidery without gaps is carried out on the same base fabric to form a long strip pattern; then the embroidery fabric is repeatedly folded into four layers, the template is placed on the top layer and then cut through with an electric cutter in one go; after unfolding, the pattern at the folds is cut incompletely, and it is difficult to align the two sides of the seam during sewing, resulting in obvious misalignment and interruption of the pattern, and the accumulation of embroidery thread at the edge causes the seam to bulge. After counting, the yield rate is only 80%.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
