Description

Technical Field

[0001] This utility model relates to the field of zipper sewing technology, and in particular to a double-layer garment half-zipper sewing template. Background Technology

[0002] To meet market demand, the design of spring and autumn sportswear has been constantly innovating. The combination of double-layered fabric and concealed zipper half-open placket has become the mainstream design direction. The double-layered fabric can balance warmth and breathability, while the concealed zipper optimizes the visual integrity of the placket, avoiding the abruptness of traditional exposed zippers and enhancing the overall fashion sense of the garment. However, this design has brought significant challenges to the production process: traditional processing methods and existing templates and tools are difficult to adapt to the complex structure of double-layered fabric, resulting in a double bottleneck in production efficiency and product quality.

[0003] From the perspective of existing processing methods, manual sewing of double-layer fabric half-zippers is a common practice in the industry, but it has many drawbacks that restrict production efficiency: poor positioning accuracy and compromised aesthetics. Manual operation involves marking positioning points before aligning the zipper, which can easily lead to crooked sewing due to hand tremors, and marker pen marks can also affect the appearance of the finished product; difficulty in controlling the fabric's stretch and insufficient structural stability. The thickness and elasticity of the double-layer fabric differ, and manual sewing involves two processes, lacking precise tension control, which can easily lead to uneven stretch. Furthermore, the positioning line of the outer zipper can damage the neatness of the inner layer; low dimensional consistency and poor standardization. The height difference of the zipper and the exposed size of the zipper cover depend on the worker's experience, and different workers have different operating habits, which can easily lead to deviations in the indicators of products in the same batch; high technical threshold and difficulty in increasing production capacity. This process requires workers to master multiple complex skills, which is difficult, inefficient, and cannot meet the needs of large-scale assembly line production.

[0004] Therefore, developing a dedicated template that adapts to double-layer fabric with concealed half-zipper, reduces operational barriers, and improves production efficiency is an urgent need for sportswear manufacturers to break through production capacity bottlenecks and ensure product quality.
