Ultra high molecular weight polyethylene covered yarn
Short description
UHMWPE Covered yarn is a super high molecular weight polyethylene fiber as the main material, according to different structures with spandex, nylon, polyester, glass fiber, stainless steel wire and other raw materials combined. Due to the excellent mechanical properties of ultra-high molecular weight polyethylene fiber, composite yarn products have anti-cutting, wear resistance and tear resistance properties, and can also have anti-puncture properties through composite. The unique cooling effect of ultra-high molecular weight polyethylene fiber makes the finished product more comfortable and cool, and has been widely used in anti-cutting gloves, anti-cutting fabric and wear-resistant shoes
To ensure protective products, relevant grade product yarn and test reports are provided in accordance with US ANSI 105 and Euro EN 388 product requirements.
