Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like figure 1 As shown, a dumbbell-shaped microporous spinneret includes a spinneret and a spinneret hole. There are 12-38 spinneret holes on the spinneret, and the shape of the spinneret holes is dumbbell-shaped. When the spinneret holes are arranged on the spinneret, the angle range between the similar long sides of the spinneret holes and the horizontal direction is The spinneret holes on the spinneret are arranged in two circles or three circles on the spinneret; the aspect ratio of the spinneret is 15-20; the radius of the dumbbell head at the two ends of the spinneret is the leaf width of the spinneret hole.

[0018] During specific use, the number of spinneret holes and the aspect ratio of the spinneret holes in the present invention can be determined according to actual needs. like figure 1 As shown, the number of spinneret holes of ...

Abstract

The invention discloses a dumbbell-shaped micro-hole spinneret, which comprises a spinneret and a spinneret hole, and is characterized in that the spinneret has 12-38 spinneret holes, and the shape of the spinneret hole is dumbbell-shaped. When the spinneret holes are arranged on the spinneret plate, the angle between the similar long sides of the spinneret holes and the horizontal direction is in the range of 45°-60°. The end of the dumbbell-shaped spinneret hole adopted in the present invention can effectively solve the dead angle caused by four right angles in the production process of the existing inline micro-hole spinneret, which improves the stability of production, and the spun The fiber has the properties of high gloss and high brightness; the dumbbell-shaped structure adopted in the invention increases the irregularity of the cross-section of the fiber, and can effectively improve the product quality and production speed of flat series polyester products. The invention has the advantages of simple structure, low cost and favorable market promotion.

Description

technical field [0001] The invention relates to a spinneret, in particular to a spinneret for producing flat polyester products, in particular to a dumbbell-shaped micro-hole spinneret. Background technique [0002] The spinneret is also called the spinning cap. The spinneret can transform the viscous polymer melt or solution through the spinneret hole into a thin stream with a specific cross-section, which is formed after being solidified by a coagulation medium such as air or a coagulation bath. silk strips. According to different types and specifications of fibers, there are different specifications, shapes, hole types and materials. Due to the dead angle caused by the four right angles of the in-line micro-holes in the production process of the existing in-line micro-hole spinneret, it is easy to cause a little melt to degrade for a long time and affect the production stability, such as too many nozzles, Disadvantages such as increased end-breakage rate and many finish...
