Abstract

The invention provides a secondary size for electronic-grade glass fiber yarn. Through research on the combined use of polyvinyl alcohol, water-based polyurethane, polyethylene glycol and lubricants, the obtained secondary size can not only protect the warp yarn to meet the requirements of High-speed weaving process requirements, but also has the performance characteristics of easy desizing, less residual fat after heat burning. The invention also provides an electronic-grade glass fiber yarn treated with the secondary size and an electronic-grade glass fiber cloth woven by using the sizing yarn.

Description

technical field [0001] The invention relates to a glass fiber sizing agent, in particular to a secondary size for electronic grade glass fiber yarn and glass fiber yarn and glass fiber cloth sized therethrough. Background technique [0002] During the weaving process of electronic grade glass fiber cloth, the warp yarn is easily damaged and hairiness occurs due to repeated friction and impact on the high-speed air-jet loom. The sizing applied during wire drawing is often difficult to meet the high-speed weaving requirements of warp yarns. [0003] In order for the warp yarns to withstand the friction and impact of the weaving process, it is usually necessary to perform secondary sizing on the warp yarns to provide more complete protection. After weaving, the glass fiber cloth also needs to undergo desizing and surface treatment, and finally become a finished electronic cloth. Therefore, in this production process, the secondary size used must not only protect the warp yarns...
