Special-shaped spinneret plate and method for producing square-section colored FDY through special-shaped spinneret plate

Abstract

The invention provides a special-shaped spinneret plate and a method for producing square-section colored FDY through the special-shaped spinneret plate. Spinneret holes in the spinneret plate are in an approximate rhombus shape of circular arc vertex angles and inward concave arc edges. Each edge of the rhombus is in an inward concave circular arc shape. Each angle is in an outward convex circular arc shape. The spinneret holes are distributed on the plane of the spinneret plate in the shape of concentric circles in a layered mode. Each layer of spinneret holes are distributed on the spinneret plate in a regular rhombus radial diagonal mode. The spinneret hole layers are arranged in a staggered mode. Sections of filament fibers spun by the spinneret plate are tightly stacked, the fibers are not likely to roll between yarn and fabric, the arrangement stacking density of the filament fibers in the fabric can be improved, and the strength, wind-proof performance and water-proof performance of the fabric can be improved.

Description

technical field [0001] The invention belongs to the field of chemical fiber textiles, and relates to a method and a device for producing square-section colored polyester yarn FDY. Background technique [0002] With the rapid economic and social development and fast-paced work and life, people's mental and psychological pressure is increasing. Outdoor sports such as mountaineering, rock climbing, crossing, zipline and bungee jumping are not only an individual professional challenge for explorers, but also have become Group sports activities for people's quality development and entertainment and fitness. [0003] The ropes and clothing used in these challenging outdoor sports require fiber materials to have characteristics and functions such as high bulk density, high strength, and good windproof performance. At present, polyester industrial yarns are mostly circular cross-sections, and ropes or fibers made of fibers Although the strength of the fabric has been improved, due ...

Problems solved by technology

[0003] The ropes and clothing used in these challenging outdoor sports require fiber materials to have characteristics and functions such as high bulk density, high strength, and good windproof performance. At present, polyester industrial yarns are mostly circular cross-sections, and ropes or fibers made of fibers Although the strength of the fabric has been improved, due to the gaps in the yarn structure of the circular cross-section fibers, the bulk density is small and the wind-shielding performance needs to be improved.
