Abstract

The invention relates to a spinneret plate, a profiled filament processed by utilizing the same and a preparation method thereof. The spinneret orifices of the spinneret plate are trilobal, are symmetrical around the x,y and z shafts which mutually form the included angle of 120 degrees and are connected by the bottom edges of the minimum circumscribed isosceles triangles A, B and C of trefoil toform an equilateral triangle D; the included angle of the side and the height of A, B or C is 5-25 degrees; the contour line bc line of the trilobal is selected from two or a plurality of and two sections of or a plurality of sections of straight lines and quadratic curves and is formed by connecting in the minimum circumscribed isosceles triangle; and the contour lines ab line and the cd line ofthe trilobal are smoothly transiting curves. The spinneret plate can be used on a fusant direct spinning device with an on-line adding function, and fiber has the characteristic of high gloss by utilizing the phenomenon that the spinneret plate and the profiled filament prepared by the corresponding spinning process have better mirror reflection effect.

Description

technical field [0001] The invention relates to textile technology, which is a fiber manufacturing technology and its products, specifically, a spinneret, special-shaped fibers processed by the spinneret and a preparation method thereof. Background technique [0002] Due to the flat surface, the special-shaped cross-section fiber has a better gloss effect than the non-flat surface fiber, and is welcomed by functional fabrics, and the added value of the fiber is higher. The excellent properties of fine denier and micro-denier fibers are also the driving force behind the increasing pursuit of fine denier for various functional fibers, such as anti-ultraviolet, antibacterial, and antistatic fibers. It can be seen that the combination of special-shaped cross-section, fine denier and functionalization will undoubtedly increase the overall value of the fiber, and has a broad market demand. However, this has high requirements on spinning equipment and technology, as well as high r...
