Abstract

The invention discloses a spinneret provided with specially-shaped holes and belongs to the technical field of viscose production. The spinneret comprises flow guide channels and spinneret holes, wherein the spinneret holes are at least divided into three groups, each group of spinneret holes comprises round holes and the specially-shaped holes, and the round holes and the specially-shaped holes are distributed in a crossing manner. Compared with the spinneret in the prior art, the spinneret can distribute a spinning solution uniformly, can produce round and flat threads, is high in flexibility and improves the smoothness and the dying property of the threads.

Description

technical field [0001] The invention relates to equipment in the field of viscose fiber production, in particular to a spinneret with special-shaped holes. Background technique [0002] In the spinning process, the spinning solution must pass through the spinneret and be cooled to form filaments of a certain size. The spinneret is an indispensable part. According to the size and shape of the spinneret hole on the spinneret Spray filaments with different shapes and functions. For example, the filaments ejected from special-shaped holes have high dyeability and dyeing uniformity, and have an obvious sense of cotton and hemp; but due to the high viscosity of the spinning solution, the fluidity Not good, the spinning liquid is easy to form a dead angle on the feeding surface, which will cause the spinning liquid to stay in the spinneret for too long, and carbonization will occur, which will affect the later production and increase the maintenance cost of the equipment. [0003]...
