Do you know about the nylon powder for the adhesive buckle of underwear

The powder particle size corresponding to the nylon powder process for underwear adhesive buttons is between 10 microns and 50 microns, which is easy to level but not easy to adhere, with high whiteness and gloss. It can be easily dyed with water-soluble acidic or dispersed dyes, and the dyeing is uniform and does not produce flowers.

This product is hygienic and environmentally friendly, and is difficult to breed bacteria. It has better contact with the skin, can withstand repeated washing and friction in the washing machine, can withstand the impact of cold and hot water cycles, and can withstand 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.

There are only two options for this series of products, white and black. During processing, small workpieces are heated to a higher temperature through a tunnel furnace and then 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. 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.
