Description

Technical Field

[0001] This invention relates to the field of high-end down jacket manufacturing processes, specifically a method for bonding adhesive strips with stitching. Background Technology

[0002] In the down jacket industry, the hot-press adhesive strip bonding process, with its characteristics of "no pinholes, high loft, and lighter weight," precisely matches the market's new demand for down jackets that are "light, warm, and beautiful."

[0003] However, in the existing traditional adhesive strip bonding process in the garment industry, an assistant worker must first pre-draw positioning baselines on the surface of the lining fabric, and then the operator manually aligns the adhesive strip with the baselines, using an iron to apply heat and fix it. This process not only places stringent demands on the operator's precise alignment ability but also requires strict control of the iron's heat-pressing parameters to avoid adhesive strip failure or substrate thermal deformation due to uneven pressure distribution or localized heat overload. Subsequently, specialized bonding equipment is used to achieve composite pressing of the fabric and lining fabric, and after 30 minutes of cooling and shaping, the down filling process can proceed according to the conventional requirement of "lining fabric facing up" during machine down filling. Before down filling, the equipment pressing parameters must be repeatedly adjusted to prevent the adhesive strip structure from cracking or shifting due to excessive pressure, which would further affect the operational stability and final product quality during "lining fabric facing up" down filling.

[0004] Meanwhile, traditional processes are highly dependent on material properties and process parameters. For materials such as polyester and nylon, which have low surface energy and are difficult to bond, or for outdoor clothing and other products that need to withstand high-frequency washing and long-term mechanical loads, adhesive layer peeling failure is prone to occur, resulting in insufficient structural strength and durability of the product, ultimately limiting both product appearance quality and production efficiency.

[0005] Therefore, in practical applications, this process is affected by material compatibility (e.g., the surface of polyester inner fabric is smooth, and existing processes are difficult to adhere firmly, making it easy to fall off; if the composite yarn layer is reinforced, the lightness and fluffiness will be sacrificed), process parameter accuracy, and consumer wearing scenarios such as washing and sports. In particular, when the product pattern is irregular, there are common industry pain points at the joints, such as the inner fabric falling off and the tube bursting, whether it is a regular adhesive strip or an X-shaped adhesive strip. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a stitching composite adhesive strip sewing method. This stitching composite adhesive strip sewing method adds stitching to the adhesive strip to create a dual guarantee of "physical fixation + chemical adhesion", which fundamentally solves the problems of insufficient strength of adhesive strip alone, easy peeling and falling off of the inner fabric and bursting of the filling tube.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A method for fabricating adhesive strips for stitching includes the following steps: S1. Template customization; Each template corresponds to a different flower pattern; Each template has a pre-defined positioning groove channel on its upper surface according to its corresponding pattern; S2. Select a template; Select a template according to the pattern required for the lining fabric pieces; place the lining fabric pieces on the upper surface of the selected template, flatten and fix them; S3. The adhesive strip is initially positioned on the upper surface of the inner fabric piece; S31. Adhesive strips are embedded in the upper surface of the inner fabric piece: The adhesive strips are embedded into the pre-made positioning groove channels of the template in sequence according to the layout of the positioning groove channels; S32. Cut the adhesive strips according to the layout dimensions of the positioning groove channel, ensuring seamless splicing at the joints of the adhesive strips; S33. Complete the initial positioning; the rubber strip embedded in the positioning groove channel is perfectly matched with the pre-made positioning groove channel in shape and size; S4. The positioning of the adhesive strip on the inner fabric piece and the stitching are completed simultaneously in one go.

[0008] Furthermore, by using the linkage control module of the template machine, the adhesive strip is positioned and fixed by sewing the sewing thread into the positioning groove channel.

[0009] Furthermore, the template machine adopts the 360 ​​template machine.

[0010] Furthermore, the sewing thread's trajectory coincides with the center line of the adhesive strip.

[0011] Furthermore, it also includes step S5, completing the bonding of the fabric and the inner lining piece.

[0012] Further, step S5 includes the following steps: S51. Lay the fabric and lining pieces overlapping each other. S52. Use an adhesive machine to heat-press and bond the adhesive strip.

[0013] Furthermore, it also includes step S6, completing the "lining up" machine down filling process.

[0014] The present invention has the following beneficial effects: 1. In response to the problem that the adhesive strip is not strong enough and easily falls off due to the smooth back of the fabric / lining material, this invention proposes a "stitching and adhesive strip process". This process adds stitching to the adhesive strip to create a dual guarantee of "physical fixation + chemical bonding", which fundamentally solves the problem that the adhesive strip alone is not strong enough, and the lining is prone to peeling off and the filling tube bursts.

[0015] 2. This invention integrates a "template machine + customized template". The initial positioning is completed by pre-embedding the adhesive strip into the high-precision positioning groove channel of the customized template. Then, with the help of the linkage control module of the template machine, the precise positioning and stitching of the adhesive strip on the surface of the lining fabric are completed simultaneously in one go. The "precise positioning of customized template" replaces the traditional manual alignment mode. No manual intervention or adjustment is required throughout the process, which reduces the dependence of the process on material properties and operating experience and significantly improves the stability of the production process. At the same time, through the application of customized template, it has the ability to be compatible with multiple materials and adapt to multiple patterns, and truly realizes the standardization and replicability of the process effect.

[0016] 3. This invention significantly enhances the structural strength and long-term durability of products through a composite fixing structure of "physical stitching anchoring + chemical adhesive strip bonding". Especially for difficult-to-bond materials such as polyester and nylon, as well as harsh usage scenarios such as outdoor clothing, physical stitching can effectively make up for the performance shortcomings of single adhesive strip bonding, achieving a fundamental improvement in product durability. Ultimately, it can achieve integrated and precise operation of adhesive strip positioning, bonding, and stitching, which not only breaks through the production efficiency bottleneck of traditional processes, but also improves positioning accuracy, ensuring the smoothness and stability of subsequent "backing fabric facing up" machine filling.
