Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a cloth positioning mechanism. Background Art

[0002] Underwear is often worn next to the body. Since it is worn inside clothes and not exposed to the outside, it must be comfortable and convenient. Briefs are usually equipped with elastic bands at the waist and leg openings, and the material of underwear is mostly pure cotton, so underwear is generally made by sewing. Because of the setting of the elastic band, it is usually stretched during sewing. After sewing, the elastic band naturally shrinks, causing the fabric joints to shrink and wrinkle. When folding and sewing into underwear, the corners are not easy to align, resulting in clumps or gaps, affecting the appearance and comfort. Therefore, how to ensure that the fabric is flat during sewing is a problem that the industry needs to solve. Utility Model Content
