The so-called free sewing button refers to a button that is attached directly to a garment by some additional device attached to the button without using a seam. These types of buttons have been around for a long time and they have a wide variety of products. Most of them are combinations of buttons, which are mainly used in some special occasions. Each type of button has been filed with a patent, so its use and production volume are limited. Function buttons are a kind of more trendy buttons. In addition to the clothing's connection function, they also incorporate some special functions that have nothing to do with button buttons, such as fragrance buttons, pharmaceutical buttons, Glow buttons, and so on. These types of buttons have all been reported as patents, and their current use is not universal, and their special features are not obvious and long-lasting.
