Problems solved by technology

In order to improve the performance of yarns, textiles made of high-performance fibers are usually selected as the reinforced structure of composite materials, among which glass fiber yarns are more used because of their advantages; the industry's requirements for glass fibers are also increasing , the existing technology is still difficult to make the glass fiber have good mechanical properties and molding properties at the same time
Therefore, by improving the basic performance of the glass fiber itself, we have developed a new glass fiber product that can guarantee higher basic performance and meet low cost at the same time; Coating equipment, although it can coat glass fiber yarn, but the operation is relatively complicated, and the coating wetting effect is average, and the problem of uneven coating coverage is prone to occur
