AI Technical Summary
During the spinning process, the filaments spun out by the spinneret tend to stick together in the duct, affecting product quality and increasing production costs.
Design a polyurethane non-sticking porous spinneret with 13 spinneret holes, 10 of which are located around the circumference and 3 between opposite spinneret holes. This layout prevents the filaments from sticking together in the channel.
This reduces the adhesion of filaments within the channel, improves the stability and uniformity of product quality, and reduces the number of times abnormal lifting and handling are required.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of spinneret, specifically points to a kind of easy-to-dye polyurethane's anti-sticking filament porous spinneret. BACKGROUND
[0002] In the spinning production process, spinneret is one of important components. After polymeric raw material passes through the spinneret orifice, it enters the duct. Since the duct is long (about 10 meters), the spun yarn follows the duct to the first floor during work. The duct has in-and-return hot air, and the yarns are prone to stick together in the duct, affecting product quality.
[0003] For example, the utility model discloses a circular porous spinneret, comprising a disc-shaped spinneret body, a plurality of uniformly arranged spinneret orifices are arranged on the spinneret body, and the special feature is that the spinneret orifice comprises a feeding hole and a spinneret hole, a containing cavity is arranged between the feeding hole and the spinneret hole; the containing cavity comprises a spherical crown-shaped upper containing cavity and a conical lower containing cavity; at least one spiral line is arranged on the inner wall of the spinneret hole. A spiral line is designed in the spinneret hole. The existence of the spiral line causes the surface of the fiber yarn to form a spiral pattern when the melt is sprayed out of the spinneret hole. The spiral pattern improves the adhesion of the dye to the surface of the yarn. However, the yarns sprayed by the spinneret often stick together in the duct during work, resulting in spiral yarns and forced reduction, affecting the AA rate, and increasing the production of waste yarns, increasing the workload of employees. SUMMARY
[0004] The technical problem to be solved by the utility model is to provide an easy-to-dye polyurethane anti-sticking filament spinneret that can produce stably.
[0005] The utility model is implemented as follows: an easy-to-dye polyurethane anti-sticking filament porous spinneret, comprising a cylindrical body, a plurality of spinneret orifices are uniformly arranged on the body, wherein a plurality of spinneret orifices are arranged near the circumferential edge, and a plurality of spinneret orifices are further arranged on the same diameter line between the two opposite spinneret orifices.
[0006] Further, the number of spinneret orifices is 13.
[0007] The utility model has the advantages that the problem of yarn sticking together in the duct is solved, the number of abnormal lifting and processing is reduced, and the stability and uniformity of product quality are improved. BRIEF DESCRIPTION OF DRAWINGS
[0008] The utility model will be further described below with reference to the drawings and in conjunction with embodiments.
[0009] Fig. 1 It is a structural schematic diagram of the utility model.
[0010] Fig. 2 The utility model discloses a spinneret plan view.
[0011] Reference signs: 1, body, 2, spinneret hole. DETAILED DESCRIPTION
[0012] The details of the utility model can be understood more clearly in combination with the description of the specific embodiments of the utility model and the accompanying drawings. However, the specific embodiments of the utility model described herein are only used for explaining the purpose of the utility model, and cannot be understood as the limitation of the utility model in any way. Under the guidance of the utility model, the skilled person can conceive any possible deformation based on the utility model, and these should be regarded as belonging to the scope of the utility model.
[0013] Reference Figs. 1-2 The embodiment provides an easy-to-dye polyurethane anti-sticking porous spinneret, which comprises a cylindrical body 1, and 13 spinneret holes 2 are arranged on the body 1, wherein 10 spinneret holes 2 are arranged near a circumferential edge, and three spinneret holes 2 are further arranged on the same diameter line between the opposite two spinneret holes 2.
[0014] The technical scheme of the utility model can avoid the problem that the filaments sprayed by the spinneret are prone to sticking in the duct, reduce the number of abnormal lifting and processing, and improve the stability and uniformity of product quality.
[0015] The above embodiment and drawing are not limited to the product shape and style of the utility model, and any ordinary skilled person in the art can make appropriate changes or modifications, which should be regarded as not departing from the patent scope of the utility model.
