Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a waist sewing mechanism for underwear. Background Art

[0002] Underwear is often worn close to the body. Since it is worn inside clothes and not exposed to the outside, it needs to be comfortable and convenient. At present, there are automated production equipment for disposable underwear in the industry to improve production efficiency and meet market demand. However, since ultrasonic waves are used for sewing in automated production equipment, and the sewing strength of ultrasonic waves is only suitable for sewing chemical fiber non-woven fabrics. Therefore, the disposable underwear manufactured by the current automated production equipment can only be made of chemical fiber non-woven fabrics. Chemical fiber non-woven fabrics are a kind of synthetic chemical fiber with poor air permeability and non-skin-friendly, which is easy to cause discomfort and is not popular with the public. At present, there is also a kind of disposable underwear made of pure cotton non-woven fabric material, which has a high degree of comfort. However, due to the nature of pure cotton non-woven fabric materials, it cannot be sewn by ultrasonic waves in automated production equipment. Therefore, the current pure cotton non-woven underwear can only be sewn by hand using sewing machines. However, the current industry is relatively tight in labor, labor costs are also rising, and operators need to have a certain experience base, which greatly increases labor costs and time costs.
