Description

Technical Field

[0001] This application relates to the field of textile technology, and more specifically, to an embroidery technique for multi-layered fabrics with sequins. Background Technology

[0002] Embroidery is a general term for various decorative patterns created on fabric using needle and thread. It involves using a needle to pierce silk thread or other fibers and yarns into the fabric with specific patterns and colors, creating decorative designs through stitches. In recent years, embroidery has gradually shifted from traditional handcraft production to large-scale industrial production. The industrial production of embroidered products mainly utilizes computerized embroidery technology. This method first involves a professional artist designing the pattern, which is then given to a pattern maker to create a pattern using specialized embroidery software. Finally, the pattern is entered into a computerized embroidery machine for embroidery.

[0003] The related technology discloses a method for embroidering patterns on an embroidery machine, which includes first drawing the pattern to be embroidered in a computer, drawing the pattern outline on a base fabric with paint, fixing the base fabric on the embroidery machine, positioning the pattern outline, and embroidering according to the pre-designed pattern. After the embroidery is completed, the embroidered base fabric is removed, cleaned, and the finished embroidery product is obtained.

[0004] Currently, the density of embroidery stitches is commonly used to express the three-dimensionality of patterns, and the brightness of the thread is used to showcase the light effect of the pattern. To achieve better patterns, it is necessary to improve the precision of embroidery and select higher-quality embroidery threads, which also leads to increased costs. In actual production, in order to reduce costs, the precision of embroidery is limited, resulting in poor three-dimensionality of embroidered products and unsatisfactory visual communication of the patterns, affecting and restricting the application of embroidered products. Therefore, improvements are needed. Summary of the Invention

[0005] In order to improve the visual communication effect of the floral pattern of embroidered products, this application provides an embroidery process for multi-layered fabrics with sequins.

[0006] The embroidery technique for multi-layered fabrics with sequins provided in this application adopts the following technical solution: An embroidery technique for multi-layered fabrics with sequins includes the following steps: Floral drawing: Draw floral patterns and input the patterns into the machine; Fabric treatment: The base layer, water-soluble protective layer, and patterned layer are overlapped in sequence and laid flat and fixed to the operating position on the machine. The machine stitches the pattern layer, water-soluble protective layer, and base layer together along the outer edge of the pattern to obtain the pattern border on the pattern layer; the machine cuts the pattern layer 0.1-2cm from the outer edge of the pattern border, removes the waste material of the pattern layer, and obtains the fabric to be embroidered. Embroidery, beadwork: The machine performs embroidery and beadwork on the fabric to be embroidered, resulting in embroidered pre-finished products with embroidered patterns. Post-processing: Dyeing, water-soluble, and setting processes yield embroidered products.

[0007] By adopting the above technical solution, the floral pattern layer is covered on the base layer, and after cutting, it forms the bottom layer of the floral pattern. Then, embroidery or bead embroidery is carried out on the floral pattern layer and the base layer, which improves the three-dimensional effect of the embroidery or bead embroidery pattern and helps to improve the visual communication effect of the floral pattern. The water-soluble protective layer can reduce the possibility of the base fabric being damaged during cutting and provide protection for the base fabric.

[0008] Preferably, the fabric processing step includes: Step 1: Stack the base layer, water-soluble protective layer, and patterned layer in sequence, and then lay them flat and fix them to the position on the machine for operation; The machine stitches the floral layer, water-soluble protective layer, and base layer together along the outer perimeter of the first part of the pattern, thus obtaining the border of the first part of the pattern on the floral layer; The machine cuts the pattern layer 0.1-2cm outside the border of the first part of the pattern, removes the waste material of the pattern layer, and obtains the first fabric. Step 2: Cover the fabric obtained in the above steps with a water-soluble protective layer and another pattern layer in sequence. The machine sews the other pattern layer, the water-soluble protective layer and the base layer together along the outer perimeter of the second part of the pattern to obtain the border of the second part of the pattern on the other pattern layer. The machine cuts another pattern layer 0.1-2cm outside the border of the second part of the pattern, removes the waste material of the other pattern layer, and obtains the second fabric. Step 3: The second fabric is the fabric to be embroidered. Directly carry out the embroidery and bead embroidery steps; or, according to the needs of the floral pattern, repeat the second step to finally obtain the fabric to be embroidered with the complete pattern, and carry out the embroidery and bead embroidery steps.

[0009] By adopting the above technical solution, multiple layers of floral patterns are combined to form a floral design, and then embroidery is carried out on multiple layers of fabric. Through the layering and combination of multiple layers of fabric, the three-dimensional effect of the embroidered floral pattern is greatly improved.

[0010] Preferably, the water-soluble protective layer is a water-soluble cloth or water-soluble paper.

[0011] Preferably, the cutting is laser cutting.

[0012] Preferably, the post-processing includes: Soak the pre-embroidered product in water until the water-soluble protective layer dissolves, then wash it. Opening the canvas, dyeing, fixing the color, and drying; After drying, place the pre-embroidered pieces into the finishing solution and soak them. Pre-drying, baking, washing, shaping, and drying are performed to obtain the embroidered product.

[0013] Preferably, the finishing solution is an anti-wrinkle finishing solution, comprising the following components in parts by weight: 0.2-1 parts chitosan, 4-10 parts polycarboxylic acid compounds, 5-8 parts sodium hypophosphite, 3-6 parts ester-based quaternary ammonium salt softener, 0.1-2 parts sorbitol, and 100 parts water.

[0014] By adopting the above technical solutions, polycarboxylic acid compounds can undergo esterification and cross-linking reactions with fabric fibers under the action of sodium hypophosphite catalyst, fixing the polycarboxylic acid compounds on the fibers and generating esterified cross-linked cellulose ethers, thereby improving the smoothness and wrinkle resistance of the fabric. Chitosan has a similar chemical structure to fabric fibers, has good adsorption and compatibility, and strong film-forming properties. Chitosan adheres to the fiber surface to form an elastic film, which can fill the gaps between fibers, restrict the relative slippage of macromolecular chains, and improve the wrinkle resistance of the fabric. In addition, the chitosan film helps to encapsulate dyes on the surface of fabric fibers, reducing the detachment of dye molecules. The amino groups of chitosan can be fixed on the fibers by undergoing amidation reactions with polycarboxylic acid compounds, which is beneficial to improving the adhesion of the chitosan elastic film to the fibers, further promoting the improvement of the fabric's wrinkle resistance. Ester-based quaternary ammonium salt softeners can improve the softness of embroidered products and enhance their hand feel. The cationic quaternary ammonium groups can adsorb anionic dye particles, making the fabric less prone to fading. A large number of hydrophilic groups on the fiber react with polycarboxylic acid compounds and are consumed, while sorbitol can attach to the fiber by combining with the amino groups of chitosan. At the same time, the large number of unbound hydroxyl groups of sorbitol can improve the hydrophilicity of the chitosan film, thereby ensuring the moisture absorption performance of the fabric and improving the wearing comfort of embroidered products. By applying finishing solutions to pre-embroidered products, the wrinkle resistance and colorfastness of the embroidered products are improved, which helps to ensure the color rendering effect of the embroidered products, further enhances the aesthetics of the embroidered products, and ensures the visual communication effect of the embroidered products.

[0015] Preferably, the polycarboxylic acid compound is selected from one or more combinations of citric acid, butanetetracarboxylic acid, malic acid, cyclopentanetetracarboxylic acid, and propanetricarboxylic acid.

[0016] Preferably, the polycarboxylic acid compound is a combination of cyclopentanetetracarboxylic acid and butanetetracarboxylic acid.

[0017] By adopting the above technical solutions, butanetetracarboxylic acid has a higher degree of crosslinking and excellent anti-wrinkle effect, but the cost is higher; cyclopentanetetracarboxylic acid has a slightly lower degree of crosslinking than butanetetracarboxylic acid, but the cyclic rigid structure in the molecule can better restrict the slippage between fiber macromolecular chains, giving the embroidered fabric better anti-wrinkle performance, and the cost is lower; the combination of the two can provide embroidered products with even better anti-wrinkle performance.

[0018] Preferably, the method for preparing the anti-wrinkle finishing liquid includes: According to the specified ratio, chitosan, polycarboxylic acid compounds, sodium hypophosphite, ester-based quaternary ammonium salt softener, and sorbitol are dissolved in water to obtain an anti-wrinkle finishing solution.

[0019] Preferably, the pre-baking includes: pre-baking at 90-120℃ for 2-5 minutes; the baking includes: baking at 150-170℃ for 2-6 minutes.

[0020] In summary, this application has the following beneficial effects: 1. In this application, the cut flower pattern layer constitutes the bottom layer of the flower pattern, and then embroidery or bead embroidery is performed on the flower pattern layer and the bottom layer, which improves the three-dimensional effect of the embroidered or beaded flower pattern and helps to improve the visual communication effect of the flower pattern; and it is preferable to use multiple flower pattern layers to combine, with multiple flower pattern fabric layers stacked together, to further improve the visual three-dimensional effect of the flower pattern. 2. In this application, an anti-wrinkle finishing agent is preferred for finishing the dyed embroidery pre-made products, thereby improving the anti-wrinkle and color-fixing properties of the embroidery products, ensuring the smoothness of the embroidery products, reducing the possibility of fading, and further ensuring the aesthetics of the embroidery products.

Opening the canvas, dyeing, fixing the color, and drying; After drying, place the pre-embroidered embroidery products into a finishing solution with a liquor ratio of 1:10, soak and tie twice, and then dehydrate. The pre-embroidered products after soaking and binding are pre-dried at 100℃ for 3 minutes, then baked at 160℃ for 4 minutes, and then washed, shaped and dried to obtain the embroidered products.

[0036] In this embodiment, the water-soluble protective layer is a water-soluble fabric, and the finishing agent is the anti-wrinkle finishing agent prepared in Preparation Example 1.

[0037] Examples 2-9 Examples 2-9 are basically the same as Example 1, except that the finishing agent is the anti-wrinkle finishing agent prepared in Example 2-9.

[0038] Comparative Example Comparative Example 1 The only difference between this comparative example and Example 1 is that it includes the following steps: The base layer is directly fixed on the machine. The machine embroiders and beadworks the base layer according to the input pattern to obtain the embroidered pre-made product. The embroidered pre-made product is soaked in 30°C water for 10 minutes to completely dissolve the water-soluble protective layer, and then washed with water. Opening the canvas, dyeing, fixing the color, and drying; After drying, place the pre-embroidered embroidery products into a finishing solution with a liquor ratio of 1:10, soak and tie twice, and then dehydrate. The pre-embroidered products after soaking and binding are pre-dried at 100℃ for 3 minutes, then baked at 160℃ for 4 minutes, and then washed, shaped and dried to obtain the embroidered products.

[0039] Performance testing test 1: Eight staff members observed the embroidered products prepared in Examples 1-9 and Comparative Example 1, and scored the three-dimensional effect of the flower pattern of each embroidered product (0-5 points). The average score of each embroidered product was then calculated, and the results were recorded in Table 1. Test 2: Wrinkle resistance: Referring to GB / T 3819-1997, the wrinkle recovery angle of the embroidered products in Examples 1-9 and Comparative Example 1 was tested. The number of washes was 10, and the results were recorded in Table 1. Test 3: Color fastness: Referring to GB / T 3920-2008, the dry and wet rubbing color fastness of the embroidered products in Examples 1-9 and Comparative Example 1 were tested respectively. The staining grade of dry and wet rubbing color fastness was assessed using the gray scale for assessing staining in GB / T251-2008 Textiles Color Fastness Test. The color difference grade was 1-5, a total of 9 levels, where grade 5 indicates no color difference and grade 1 indicates a large color difference. The results are recorded in Table 1. Test 3: Referring to AATCC TS 017, the moisture absorption properties of the embroidered products in Examples 1-3 and Example 9 were determined, and the results were recorded in Table 1.

[0040] Table 1 Combining Examples 1 and 2 with Table 1, it can be seen that the multi-layer fabric embroidery process with sequins disclosed in this application can improve the visual communication effect of embroidered products. The overlapping of multiple floral patterns greatly enhances the three-dimensionality of the patterns. While ensuring low cost, it improves the aesthetics of embroidered products and is conducive to large-scale production.

[0041] Based on Examples 1-3 and Table 1, it can be seen that applying the method disclosed in this application to anti-wrinkle finishes embroidered products can give them better flatness and colorfastness, reducing the possibility of water washing wrinkles or fading that would lower the visual communication effect of the embroidered products.

[0042] Based on Examples 1, 4, and 5-8, and in conjunction with Table 1, it can be seen that the combination of cyclopentanetetracarboxylic acid and butanetetracarboxylic acid can further improve the wrinkle resistance of embroidered products and promote colorfastness. This may be because butanetetracarboxylic acid has a higher degree of cross-linking and greater flexibility, while cyclopentanetetracarboxylic acid, with its rigid structure, can complement butanetetracarboxylic acid, restricting the slippage between the fabric fiber macromolecular chains and giving the fabric better wrinkle resistance.

[0043] Based on Examples 1-3 and Example 9, and in conjunction with Table 1, it can be seen that sorbitol can help improve the wicking rate of embroidered products, thereby improving their moisture absorption efficiency and wearing comfort. This may be because sorbitol helps increase the hydrophilic groups on the surface of fabric fibers, promoting the increase of fiber hydrophilicity and improving the moisture absorption performance of embroidered products.

[0044] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
