How to apply specialized nylon powder for underwear accessories

Before the introduction of nylon powder coating to China, underwear was sprayed twice on the front and back of the underwear buckle. However, this coating is not wear-resistant and is not resistant to cold and hot water immersion. Often, after several washes, the coating is prone to peeling off, resulting in "0" 8 The initial use of liquid epoxy coating for each coating of "9" gradually replaced the traditional epoxy spraying process with the introduction of specialized nylon powder coating for underwear accessories from abroad, in order to prevent rust and improve aesthetics.

There are only two options for specialized nylon powder for underwear accessories, white and black. During processing, small workpieces are heated to a higher temperature through a tunnel furnace and enter a closed fluidized vibration plate to be coated with powder. Due to the small size of the workpiece and insufficient heat capacity, the surface floating powder needs to be melted and leveled. A second heating is needed to melt and level the surface floating powder on the button, and then dyed according to the color of the underwear to make it. The biggest feature of this process is that it achieves a hanging point free effect through the vibration of the vibrating disc that cannot be achieved by other construction techniques. The coating is complete and beautiful, and the domestic equipment technology is mature, with high production efficiency. It can reach a scale of 1 million pieces per shift per machine. It is said that 80% of the world's underwear buttons are produced in China.

Nylon powder for underwear accessories is hygienic and environmentally friendly, and is difficult to breed bacteria, providing better contact with the skin. It can withstand repeated washing and friction by washing machines, the impact of cold and hot water cycles, and the high-temperature process of drying. It can also meet the needs of colorful underwear and be easily dyed through its own coating to achieve the desired color.

The particle size of the specialized nylon powder for underwear accessories corresponding to this process is between 10 microns and 50 microns, which is easy to flatten but not easy to adhere, has high whiteness and gloss, and can be easily dyed with water-soluble acidic or dispersed dyes, and the dyeing is uniform and non floral.
