Description

Technical Field

[0001] This invention relates to the field of garment sewing technology, specifically a special sewing process method that synchronizes the top and bottom sewing lines. Background Technology

[0002] Garment sewing refers to the process of connecting components of different fabrics using stitches to complete the garment production. This is a crucial step in garment manufacturing, directly determining the quality and appearance of the garment. Various sewing machines and techniques are typically used in garment sewing. Common sewing methods include straight stitch, overlock stitch, curved stitch, and backing stitch. Different sewing methods are suitable for different fabrics and design requirements. To achieve synchronization between the fabric and the garment's stitch lines, sewing workers need to possess excellent skills and utilize appropriate equipment and tools. They must precisely control the tension of the sewing thread, the neatness of the stitches, and the durability of the seams to ensure the garment meets quality requirements.

[0003] Double-sided sewing is a special sewing technique that stitches two pieces of fabric together simultaneously, resulting in a seamless appearance on both sides. This technique is commonly used in garments, home textiles, and other fabric products where a seamless connection between inner and outer fabrics is required. Double-sided sewing typically requires a double-needle sewing machine, which stitches two lines simultaneously: one on the right side of the fabric and the other on the back. By adjusting the stitch spacing and tension of the double-needle sewing machine, a precise connection between the two fabrics can be achieved. Double-sided sewing allows for fabric joining without post-processing, preventing the inner fabric of garments or textiles from being exposed, while providing a more aesthetically pleasing appearance and a more comfortable wearing experience.

[0004] However, double-sided sewing cannot produce a style with consistent front and back effects in one operation, which reduces production efficiency. Therefore, in view of this, we have studied and improved the existing technology and proposed a special sewing process method that synchronizes the front and back lines. Summary of the Invention

[0005] This invention provides a special sewing process that achieves consistent results on both sides of the garment in a single sewing operation, thereby improving efficiency by synchronizing the front and back sewing lines.

[0006] The technical solution adopted in this invention is: a special sewing process method for synchronizing the front and back seams, including the selection of double-sided cold transfer fabric, and the specific double-sided sewing steps are as follows:
