<p>The present invention relates to a treatment process for flattening electronic-grade glass fiber cloth and the electronic-grade glass fiber cloth produced by using same. First, the yarns are wound on the warp beam while sizing the yarn monofilament to take the sizing finishing process, and then the obtained warps are combined and woven to get fatty glass fiber cloth. Subsequently, the obtained fatty glass fiber cloth is set in a steaming oven for fumigating and swelling. With the effect of the ejection and fumigation of the saturated steam under the high temperature and high humidity environment, the highly expansive starch among the yarns swells rapidly under the heat and humidity, and the spaces among yarn bundles increase when the yarn bundles are kept under the high temperature and high humidity environment for some time to form secondary structural reorganization. And subsequently, the obtained swollen glass fiber cloth is heated continuously and stewed to degrease under the high temperature. Finally, the obtained degreased glass fiber cloth is opened by high-pressure injection, extruded to eliminate excess water, and impregnated with a silane coupling agent through a surface processing machine.</p> |
