Introduction: Quartz fiber untwisted yarn Quartz fiber untwisted yarn is a yarn formed by infiltrating continuous quartz fibers without twisting and plying. Untwisted yarn has better wettability and can be directly used to make various composite materials, and can also be used as the base material of cotton felt or needled felt

Quartz Fiber Sewing Thread It is made of high-twist quartz fiber yarn coated with a high-temperature-resistant lubricating layer. The surface of the sewing thread is smooth, flexible, and has good folding resistance. It can be directly used on industrial sewing machines and can fully replace glass fiber sewing thread, high silica sewing thread, etc. Ideal suture material for 3D preforms
