Spinneret plate for chemical fiber yarn production

Abstract

The invention discloses a spinneret plate for chemical fiber yarn production, and belongs to the technical field of textile production equipment. The spinneret plate comprises a plate body; grooves are formed in the upper surface of the plate body; spinneret holes are formed in the inner wall of the bottom surface of the corresponding grooves; a conical groove A is formed in the opening end of theupper end of each spinneret hole, and a conical groove B is formed in the inner side wall of each spinneret hole; and clamping grooves are formed in the upper surface of the plate body, and connecting holes are formed in the inner walls of the bottom faces of the corresponding clamping grooves. Chemical fiber raw materials can be effectively separated and temporarily stored through the grooves formed in the upper surface of the plate body, it is guaranteed that the chemical fiber raw materials always exist in the spinneret holes, and then the chemical fiber raw materials can be preliminarilypolymerized through the conical grooves A formed in the spinneret holes; and the chemical fiber raw materials can be further subjected to secondary polymerization through the formed conical grooves B,the quality of chemical fiber yarns of the product is guaranteed, and the spinneret plate is simple in structure, relatively high in practicability and suitable for being widely used and popularized.

Description

technical field [0001] The invention relates to a textile production equipment accessory, in particular to a spinneret for chemical fiber yarn production. Background technique [0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and solidify through a coagulation medium such as air or a coagulation bath to form filaments. [0003] Patent No. CN 201220388916.5 discloses a spinneret for chemical fiber yarn production, which adopts crescent-shaped spinneret holes with arcs at both ends to increase the surface area of ​​the fiber, and the difference between the static friction system and the dynamic friction coefficient of the fiber is large, so that the friction between the fibers The cohesive force is increased, it is not easy to fluff and pilling, the bulkiness is improved, and the air permeability is good; the combinati...

Problems solved by technology

[0004] Although the above-mentioned patented solution solves the shortcomings of the traditional spinneret for chemical fiber yarn production, there are still some shortcomings in this solution. 2. Most of the existing spinnerets for chemical fiber yarn production are difficult to disassemble and install, resulting in inconvenient repair and maintenance of the spinnerets; for this reason, we propose a spinneret for chemical fiber yarn production to solve the above problems.
