Production method for super-low-twisted electronic grade glass fiber cloth

Abstract

The invention discloses a production method for super-low-twisted electronic grade glass fiber cloth. The method comprises the steps of: carrying out warping, sizing and other processes on 20 twist glass fiber yarns, weaving the glass fiber yarns to form grey fabric, carrying out desizing, surface coupling and a process of fiber opening on the glass fiber grey fabric to obtain finished products. Compared with super-low-twisted electronic grade glass fiber cloth employing 28 twist glass fiber yarns in the prior art, the super-low-twisted electronic grade glass fiber cloth employing 20 twist glass fiber yarns in the invention has a higher stiffness and a higher adhesive rate of impregnating compound, relatively better flying performance of the weft yarns, lower pressure on a main nozzle, better permeability of resin, and the like.

AI Technical Summary

Benefits of technology

This patented technology uses specialized chemical agents called polyvinyl alcohol (PVOH) or polyglycerol ester oil(POE), together with specific types of polymers like vinyl acetates copolyester elastomeric block copolymers). These chemistry allow these materials to form strong films on woven fabrics without causing damage from abrasives such as nails used in machining processes. Additionally, this method allows for improved flexibility and durable properties over traditional methods while maintaining excellent resistance against heat shock. Overall, it provides technical benefits including increased strength, less flaking, smoother surfaces, enhanced resiliency, prevented unwanted appearances caused by friction between fibers, reduction of noise levels associated with machine operation, and more precise control over how much liquid insulation material flows through an opening within the shedding mechanism of the garment's seamless edge joint.

Problems solved by technology

This patented technical solution involves improving the production efficiency of electronics grade (EG) glass woven cloth due to its use in various applications like communication devices or military vehicles. Specifically, it addresses issues caused by poorly formed surfaces called rough texture at the edges where there may come into contact with other components. To address these concerns, an improved method was developed involving adding specific types of chemical agents onto the glass fabric before forming the final product. These chemically treated threads can improve their durability without causing any unwanted side effects.
