Abstract

The invention provides electronic-grade glass fiber yarn secondary slurry. Polyvinyl alcohol, waterborne polyurethane, polyethylene glycol and a lubricating agent are matched to be used and researched, so that the prepared secondary slurry not only can protect warps and meet a high-speed weaving technology requirement, but also has the characteristics of easiness in desizing, small residual fat content after thermal burning off and the like. The invention further provides an electronic-grade glass fiber yarn treated by the secondary slurry and an electronic-grade glass fiber cloth woven by thesized 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...
