Drain plate for preparing electronic grade spun yarns and electronic grade spun yarn preparation method

Abstract

The invention discloses a drain plate for preparing electronic grade spun yarns. Novel drain nozzle distribution is adopted on bottom plates, so that the production efficiency is greatly improved at the same time of ensuring that the quality of products does not decline. The bottom plates of the drain plate are divided into five areas in totally same size, shape and arrangement mode, the drain nozzles of each area are arranged in a mode of fillet parallelogram array consisting of 12 columns and 17 rows, and the fillet parallelogram array is formed by respectively removing one drain nozzle on four corners from the parallelogram array consisting of the drain nozzles and provided with 200 drain nozzles. The drain nozzle fillet matrix of the novel drain plate is more symmetrical compared withthe drain nozzle fillet matrix of 13 columns and 16 rows of an 800-pore drain plate, so that the glass silk distribution is more uniform in the subsequent process and the product yield is increased at the same time of ensuring the product quality. Meanwhile, the subsequent process of drain plate production is correspondingly improved.

Description

technical field [0001] The invention relates to a bushing for glass fiber drawing and a preparation method using the bushing, in particular to a bushing for preparing electronic-grade spun yarns and a method for preparing electronic-grade spun yarns using the bushing. Background technique [0002] Electronic grade spun yarn is a continuous glass fiber made from "E" glass. It is mainly used for weaving electronic fabrics, and can also be used for industrial purposes such as the production of bulked yarns and twisted yarns. Its characteristics include: adding starch-type sizing agent; stable linear density of raw silk; good fiber cohesion, moderate softness, good wear resistance, small wool yarn; high single-filament strength. [0003] The common manufacturing method of glass fiber is to discharge multiple bundles of molten glass from the heating bushing, draw the glass bundles into fibers, send them to the oiler to coat the fibers with sizing agent, and then integrate the fi...

AI Technical Summary

Problems solved by technology

[0005] Due to the low production efficiency of the 800-hole bushing plate, the economic benefits that the electronic spinning yarn should have have not appeared, and its production efficiency needs to be further improved

Practice has found that simply increasing the number of bushing holes will cause problems such as difficulty in wire drawing, uneven single fiber diameter, glass crystallization, woolen yarn, broken yarn, etc., which will reduce the quality of spun yarn in the subsequent process, and will not only fail to improve production efficiency , but reduces the product quality
