Plasma treatment technology improves the surface properties of leather through physical and chemical interactions, and is widely used in pre bonding treatments for automotive interiors and other fields. It has the effects of cleaning, activating surfaces, and enhancing adhesion.

Application scenarios

Automotive interior wrapping: Processing plastic frames or leather surfaces to solve problems of delamination and wrinkling during bonding, increasing bonding strength by more than 50%.  ‌

Seat wrapping process: Improve the surface energy of PP/ABS and other materials, making PVC synthetic leather and other wrapping materials more compatible.  ‌

Instrument panel manufacturing: Remove residual release agents, improve coating adhesion, and extend durability.  ‌

Polyester fiber is a high-quality synthetic fiber used to produce high strength sutures, ranking second only to nylon thread among various types of sutures, and does not reduce strength when wet. Its shrinkage rate is very small, and after proper shaping, the shrinkage is less than 1%, so the sewn thread can always maintain a flat and beautiful appearance without wrinkles. Wear resistance is second only to nylon. Low moisture regain, good resistance to high and low temperatures, light and water. So, polyester thread is a widely used variety that has replaced cotton sewing thread in many occasions. Polyester thread has a wide range of applications, including sewing cotton fabrics, synthetic fabrics, and blended fabrics, as well as sewing knitted outerwear. Specially made polyester thread is still an excellent thread for the shoe, hat, and leather industry.
