High-efficiency low-cost weaving technique for electronic grade glass fiber cloth

Abstract

The invention belongs to the technical field of preparation of glass fiber cloth, and particularly relates to a high-efficiency low-cost weaving technique for electronic grade glass fiber cloth. The weaving technique comprises the following steps: adding a raw material substance containing quartz sand, limestone, soda ash, a co-solvent and a clarifying agent into a smelting furnace, mixing and dissolving to obtain a eutectic, and then performing high-speed spinning through a platinum leakage plate to prepare a glass fiber finished yarn product; wrapping the warp yarn prepared in Step 1 in a special paraffin type wetting agent without secondary sizing; arranging the warp yarn according to the number of 1,628, and directly finishing the shaft; feeding a finished warp beam onto an air jet loom, inserting weft on the air jet loom, and interweaving the yarn at different warp and weft densities to prepare a glass fiber gray fabric; and performing surface treatment on the woven glass fiber gray fabric to prepare the glass fiber cloth finished product. The technique provided by the invention is scientific, reasonable, simple and feasible, and the production efficiency is improved by 20 percent or above; and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of glass fiber cloth preparation, and in particular relates to a high-efficiency and low-cost electronic-grade glass fiber cloth weaving process. Background technique [0002] At present, a kind of electronic grade glass fiber cloth commonly used in the market is imitation 7628 variety, its basis weight is 208g / ㎡, thickness is 0.175mm±0.017mm, warp and weft are made of G75 starch yarn, warp and weft density is 44×32 / in, warp yarns are woven into warp beams after secondary sizing is applied. [0003] There is a huge problem in this situation: in the case of tight supply of G75 starch yarn, there is no alternative yarn type, which directly affects the use of downstream customers. Therefore, it is necessary to find a yarn type that can replace G75 without affecting the quality of the product. Quality is what the industry needs to focus on. [0004] In addition, this production method requires secondary sizin...

Problems solved by technology

[0003] There is a huge problem in this situation: in the case of tight supply of G75 starch yarn, there is no alternative yarn type, which directly affects the use of downstream customers. Therefore, it is necessary to find a yarn type that can replace G75 without affecting the quality of the product. Quality is what the industry needs to focus on

[0004] In addition, this production method requires secondary sizing, which is costly and restricts the development of the industry

At the same time, the warp density is generally greater than 40 yarns / inn during production, and the number of warp yarns is generally greater than 2000 yarns, which affects production efficiency
