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...
