Problems solved by technology

[0005] Due to the low production efficiency of the 800-hole bushing plate, the economic benefits that electronic spinning yarns such as ultra-fine yarn D450 should have have not appeared, and their 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

Embodiment Construction

[0038] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0039] Figure 1a It is the layout diagram of the bushing plate of the present invention. It can be seen from the figure that the bushing plate is a single-layer bushing plate with a thickness of 1.7mm, which can prevent the deformation caused by the temperature difference between the upper and lower surfaces of the bushing plate. The leak board is divided into 12 areas with the same size, shape and distribution on average. The leaks in each area are arranged in a rounded matrix with 9 columns and 12 rows, that is, each area is a matrix composed of 9 columns and 12 rows. A rounded corner matrix with 100 leaks with a total of 8 leaks in the corner, therefore, a total of 1200 leaks in 12 areas. Those skilled in the art can imagine that the arrangement of the nozzles on the bushing can be a certain form of rounded parallelogram arrangement, such as a round...

Abstract

The invention relates to a bushing for preparing electronic spun yarns, which is characterized in that a base plate adopts a novel discharge spout distribution scheme, thereby ensuring that the quality of products is not reduced and greatly improving the production efficiency. In the invention, the bottom of the bushing is divided into 12 regions which are identical in the aspects of size, shape and distribution mode, wherein a rounded parallelogram composed of 100 uniformly distributed discharge spouts (i.e. a parallelogram composed of discharge spouts in 9 columns and 12 rows excluding 8 discharge spouts at 4 corners) is formed in each region. Compared with the 13-column and 16-row discharge spout rounded matrix of a 800-nozzle bushing, the novel bushing provided by the invention is more symmetrical, so that glass fibers can be distributed more uniformly in the subsequent process, thereby ensuring the product quality and improving the product yield. The invention also correspondingly improves the subsequent production process of the bushing.

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] Superfine yarn D450, as one of the products with high technical content and added value in spinning products, has always been the priority development target of various fiberglass companies. 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-based sizing agent; stable raw silk linear density; 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 ...
