Abstract

The invention provides a hollow spinneret plate and a use method thereof. The hollow spinneret plate comprises a spinneret plate body, a flow guide groove, a spinneret hole, a heating component and apower connection component, the flow guide groove is formed in the front surface of the spinneret plate body, the spinneret hole is formed in the back of the spinneret plate body, the heating component is arranged inside the spinneret plate body, and the power connection component is arranged on one side of the spinneret plate body. According to the hollow spinneret plate and the use method thereof, remaining of high polymer melts or solution on the spinneret plate body can be greatly decreased, waste of the high polymer melts or solution is greatly reduced, the high polymer melts or solutioncan be kept in a molten state when entering the spinneret hole by heating the inside of the spinneret hole, so that spinneret effects are better, coagulated high polymer melts remaining on the inner wall of the spinneret hole can be conveniently cleaned, blockage of the spinneret hole is prevented, and the coagulated high polymer melts can be collected and reused.

Description

technical field [0001] The invention relates to the field of spinnerets, in particular to a hollow spinneret and a method of using the same. Background technique [0002] The spinneret is also called the spinning cap. The function of the spinneret is to convert the viscous polymer melt or solution into a thin stream with a specific cross-section through micropores, and solidify it through a coagulation medium such as air or a coagulation bath to form a filament. [0003] In the process of spinning the polymer melt or solution with the spinneret, the polymer melt or solution begins to cool when the polymer melt or solution flows into the spinneret and enters the spinneret hole. The polymer melt or solution near the outside is partially cooled and solidified, which affects the quality of the spinneret. At the same time, after the spinneret, part of the polymer melt or solution will remain in the spinneret hole and solidify on the inner wall of the spinneret hole for a long ti...
