Embodiment

[0038] The making of A component / B component two kinds of macromolecular polymer lotus-shaped fibers: A component, B component are by the ratio of 40 / 60, arrive at the device of the present invention by melt extruding respectively in screw extruder, in The device of the present invention passes through respective independent flow channels, and finally converges at the exit of the spinneret to form a fiber of multiple B component filaments surrounded by A component. Through post-processing reduction treatment, lotus root-shaped fibers are finally formed.

Abstract

The invention discloses a lotus-root-shaped fiber spinning pack and belongs to the technical field of spinning pack equipment. The lotus-root-shaped fiber spinning pack comprises ten distributing plates which are fastened together by using fourteen high-strength bolts. Two high-molecular polymers A and B pass through respective flow passages in each distributing plate and are cooled by air when the polymers exit the last distributing plate to form a plurality of yarns with one component enclosed by the other component. Lotus-root-shaped fibers produced by using the lotus-root-shaped fiber spinning pack have the advantages that the coverage is high, the strength, bonding performance and specific surface area are better, the creases of leather products produced after post-processing are delicate, the formability is good, the anti-aging performance is good and the wearing comfort is good.

Description

technical field [0001] The invention belongs to the technical field of spinning assembly equipment, and in particular relates to a hole-shaped fiber spinning assembly. Background technique [0002] The lotus-shaped fiber is named because there are continuous round holes inside the fiber, and its cross-section looks like the internal structure of the lotus root under a microscope, so it is named lotus-shaped fiber. Lotus fiber is mainly used in the leather industry and is the main raw material for making imitation leather. The products made of ordinary PU artificial leather have shortcomings such as no air permeability, hard hand feeling, low strength and easy aging, etc., and are increasingly abandoned by people. [0003] The invention of lotus root-shaped fiber solves all the shortcomings of PU artificial leather. Because of the continuous round holes inside, lotus root-shaped fiber has good air permeability, which solves the shortcomings of other fibers that are not air-ti...
