Weaving process of high-efficiency and low-cost electronic grade glass fiber cloth

Abstract

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. The weaving process method includes the following steps: adding raw materials including quartz sand, limestone, soda ash, co-solvent and clarifying agent into a melting furnace, mixing and dissolving them into a eutectic, and then spinning through a platinum bushing plate at high speed to prepare Glass fiber finished yarn; the warp yarn prepared in step 1 is coated in a special paraffin-type sizing agent, without secondary sizing; the warp yarns are arranged according to the number of 1628, and the shaft is directly assembled; the completed warp shaft is placed on the air jet On the loom, the weft is inserted on the air-jet loom, and different warp and weft densities are interwoven to form a glass fiber gray cloth; the woven glass fiber gray cloth becomes a finished glass fiber cloth after surface treatment. The technological method provided by the invention is scientific and reasonable, simple and easy to implement, improves the production efficiency by more than 20%, and reduces the production cost.

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
