The core material is made of high-shrinkage elastic nanofibers to strengthen the synthesis of nylon silk, and titanium wire is added to maintain a stable feather tension for a long time. The coating layer is made of special flat monofilament fibers and microfibers. The 0.7 mm wire diameter and special weaving method make good durability and vibration absorption coexist, and it has very good performance in vibration absorption, beating resistance and other properties
