Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0018] A preparation process of glass fiber cloth, the steps are:

[0019] (1) Manufacture of gray cloth: pass several glass fiber raw yarns through a single row carding and warping process, and then use a pulper to adjust the warp beam;

[0020] (2) Paralleling: the warp and weft yarns are mixed with each other, and after merging, the yarns are put into the sizing tank to soak the sizing, and the wet sizing yarn after the sizing tank is spun into the heat drying area for drying until the moisture content is ≤ 10%, and Shaft weaving into gray cloth;

[0021] (3) The first thermal cleaning: burn the organic matter such as slurry on the glass fiber cloth from 8% to 0.5-1.6%;

[0022] (4) The second heat cleaning: put the glass fiber cloth into the stuffy furnace for the second heat clea...

Abstract

The invention relates to the field of glass fiber cloth manufacturing, and discloses a preparation technology of glass fiber cloth. The preparation technology comprises the steps of manufacturing grey cloth, rebeaming, and performing first thermal cleaning, second thermal cleaning, air airing and surface treatment. The glass fiber cloth has outstanding high temperature resistance, and good ablation performance, and an insulation grade of an electrotechnical product is raised.

Description

technical field [0001] The invention relates to the field of textile manufacturing, in particular to a preparation process of glass fiber cloth. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance, and its components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It uses glass balls or waste glass as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes. Finally, various products are formed. [0003] Because glass fiber has excellent electrical insulation performance and high temperature resistance, it is beneficial to improve the insulation level of electrical products, prolong the service life, and can meet the special requirements of electrical products. Therefore, electronic grade glass fiber cloth has become one of the main raw materials in the copper clad laminate industry. First, it is the product with the largest amount of gl...
