Description

Technical Field

[0001] This utility model relates to the field of bath towel production technology, and more specifically, it relates to a sewing machine for bath towel production. Background Technology

[0002] With the improvement of people's living standards and pursuit of quality of life, the market demand for bath towels, as an essential item in daily life, is constantly growing. The production scale of bath towels is gradually expanding, and the production process is becoming increasingly sophisticated. Modern bath towel production not only focuses on the basic properties of bath towels such as material, absorbency, and softness, but also continuously innovates in appearance design and size specifications to meet the needs of different consumers. Proper edge stitching can make the edges of the bath towel smoother and reduce friction on the skin. Especially when in direct contact with human skin, rough edges can cause discomfort, while fine edge stitching can improve the user experience. However, hand sewing is inefficient and has high labor costs. Hand sewing requires a significant investment of time and manpower, and with the continuous rise in labor costs, this is a considerable burden for bath towel manufacturers. Especially in large-scale production, hand sewing cannot meet production schedule requirements, resulting in poor quality stability. Due to differences in manual operation, different workers have varying levels of sewing skills, making it difficult to guarantee product quality consistency. Even with the same worker, the quality of the sewing may fluctuate under different working conditions, such as uneven stitches or inconsistent thread tension. Therefore, in order to solve the above-mentioned technical problems, this application proposes a sewing machine for bath towel production. Summary of the Invention
