Spinning assembly and spinning part

Abstract

The invention discloses a spinning assembly and a spinning part. The spinning assembly is used for producing polyurethane fibers and comprises a metering device and the spinning part, wherein the metering device is provided with one inlet and a plurality of outlets, the inlet is connected with a filtering and pressure stabilizing device, the outlets are directly connected with the spinning part, the spinning part is a box body with a cavity, the box body is internally provided with holes of different numbers, the number of the holes corresponds to the number of the polyurethane fibers in each spinning station, a filter and a spinneret are arranged inside each hole, the outlets of the metering device are correspondingly connected onto the holes of the spinning part, and the centers of the outlets of the metering device and the centers of the holes of the spinning part are homocentric. According to the invention, the production quality of the polyurethane fibers can be increased, the production efficiency can be increased, and the spinning assembly and the spinning part are simple and rapid to install and maintain.

Description

technical field [0001] The invention relates to an equipment and a method for realizing raw material supply in polyurethane dry solution spinning by metering, distributing and forming multi-beam solution flows of polyurethane chemical solution. Background technique [0002] In the polyurethane fiber dry production process, chemical raw materials are polymerized to form a polymer solution, and the polymer solution is transported to the metering device of each spinning station through pipelines, and the metering device forms multiple streams of solution through metering and distribution. [0003] Figure 6-8 The structure of a prior art device is shown. In existing equipment, the polymer solution is transported to the metering device through pipelines. The metering device generally has one inlet and multiple outlets. In the metering device, the polymer solution is distributed into multiple smaller solution streams. The solution flow is connected to the spinning part through a...

AI Technical Summary

Problems solved by technology

Cleaning a large number of metal hoses with different bending degrees and lengths requires a lot of work, which also affects production efficiency

In addition, part of the solidified particles will also become impurities in the polyurethane solution, which will aggravate the clogging of the spinneret

[0007] In addition, each metal hose needs to be removed when cleaning the spinneret, which takes a long time, and a lot of polymer solution is wasted in order to eliminate the gas entering the metering device due to the replacement of the spinneret
