Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that the existing spinneret for spinning fine denier yarn is prone to stagnation when it flows in the micropores, the quality of the obtained product is poor, and the effect of moisture absorption and perspiration is not good, and a production quality control method is proposed. High, improve its dyeing effect, can produce "X" type microporous spinneret with good air permeability and performance close to cotton fiber

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0010] As shown in Fig. 1, a kind of " X " type microporous spinneret comprises spinneret plate surface 1, and spinneret plate surface 1 is provided with spinneret microhole 2, and one side of spinneret microhole 2 is for The feed port, the other side is the discharge port, the shape of the spinneret plate surface 1 is circular, the shape of the spinneret microholes 2 is "X", the number of microholes is 30-40, and the number of microholes is preferably 36 . The middle angle of the "X" type spinneret microhole is 110°~130°, which can significantly reduce the stagnation phenomenon during the flow in the melt microhole. On the spinneret plate surface 1, the leaf width of the "X"-shaped spinneret microholes 2 is 0.1-0.15 mm, and the ratio of leaf length to leaf width is 12-18. The described spinneret microholes 2 are arranged in a three-layer concentric c...

Abstract

The invention discloses an X-type micro-hole spinneret plate which comprises a spinneret plate face (1). Spinneret micro-holes (2) are formed in the spinneret plate face (1), feeding openings are formed in one sides of the spinneret micro-holes (2), discharging openings are formed in the other sides of the spinneret micro-holes (2), and the spinneret plate face (1) is circular. The X-type micro-hole spinneret plate is characterized in that the spinneret micro-holes (2) are in X shapes, and the number of the spinneret micro-holes (2) ranges from 30 to 40. FDYs produced through the X-type micro-hole spinneret plate are beneficial for improving the cooling effect of nascent fibers, the cooling evenness of the FDYs is improved, the obtained products are high in quality, and the moisture absorption performance and the air permeability of fabric can be remarkably improved.

Description

technical field [0001] The invention relates to a spinneret, in particular to an "X" type microporous spinneret. Background technique [0002] The spinneret, also known as the spinning cap, can transform the viscous polymer melt or solution into a thin stream with a specific cross-section through the spinneret hole, and form filaments after being solidified by a coagulation medium such as air or a coagulation bath. [0003] At present, the existing spinnerets are relatively primitive for the production of special-shaped polyester FDY yarns, and the melt is prone to stagnation when it flows in the micropores, resulting in poor product quality, poor dyeing effect, and difficulty in showing bright colors, and The obtained fabric has poor hygroscopicity and perspiration performance, which cannot meet the requirements of the prior art. Contents of the invention [0004] The purpose of the present invention is to solve the problems that the existing spinneret for spinning fine ...
