Buttonholes and buttons in Jean Ski Jacket are usually processed by machines. According to their shapes, buttonholes are divided into two types: flat and eye holes, commonly known as sleeping holes and pigeon eye holes.
Straight eyes are widely used in shirts, skirts, pants and other thin clothing products.
Water hyacinth is mostly used on outerwear of thick fabrics such as coats and suits.
The keyhole should pay attention to the following points:
(1) Is the buttonhole position correct?
(2) Whether the size of the buttonhole matches the size and thickness of the button.
(3) Whether the buttonhole opening is well cut.
(4) For stretchy (elastic) or very thin fabrics, consider adding cloth to the inner layer when using keyholes. The sewing of the button should correspond to the position of the buttonhole, otherwise the garment will be twisted and skewed due to the inaccurate button position. When buttoning, attention should also be paid to whether the amount and strength of the button thread are sufficient to prevent the button from falling off, and whether the number of button threads on thick fabric clothing is sufficient.
