Description

Technical Field

[0001] The invention belongs to the technical field of sewing, and in particular relates to a presser foot used for four-thread seaming of hot-drilled fabrics. Background Art

[0002] In the field of clothing production, hot-drilled fabrics are highly favored for their unique decorative effects. Hot-drilled fabrics add a dazzling and gorgeous visual effect to clothing by attaching hot-drilled diamonds to the surface of the fabric. They are widely used in fashion clothing, stage costumes and various high-end custom-made clothing.

[0003] However, there are many technical difficulties in processing hot-drilled fabrics. The hot-drilled fabrics on existing hot-drilled fabrics will make the surface of the fabric uneven. When performing the common sewing process of four-thread stitching, this uneven surface will easily cause the sewing process to jam. The unsmooth operation of the sewing machine not only greatly reduces production efficiency, but also may cause problems such as uneven sewing lines and skipped stitches, seriously affecting product quality.

[0004] At the same time, due to the presence of hot drilling, the friction between the presser foot and the fabric is uneven during the four-line stitching process, and the local friction is too large, which makes the fabric at risk of being worn out. Once the fabric is worn out, it can no longer be used for normal product production, resulting in a waste of raw materials and increased production costs.

[0005] In addition, in order to avoid the above-mentioned adverse effects of hot-drilling on the four-line seams, the commonly used method is to manually remove the hot-drilling at the seam position before sewing. However, this manual drilling operation method not only consumes a lot of manpower and time, but also leaves offset marks on the fabric after the drilling is removed, which are difficult to clean. These offset marks seriously affect the appearance quality of the fabric, resulting in the quality of the final product failing to meet high standards and making it difficult to meet the market demand for high-quality clothing products.

[0006] In summary, the existing four-thread stitching process for hot-drilled fabrics has many technical defects, and it is urgent to develop a new presser foot that can solve these problems in order to improve the processing quality and production efficiency of hot-drilled fabrics.
