Composite fiber wrapped yarn and preparation method thereof

Abstract

The invention discloses composite fiber wrapped yarn and a preparation method thereof, and belongs to the technical field of composite fiber wrapped yarn processing. The method comprises a rack; a softening tank is fixedly connected with the bottom on the inner side of the rack; a penetrating hole is formed in the side surface of the softening tank; a first softening foam plate is arranged on theside surface of the softening tank at the position corresponding to the penetrating hole; and an electric heater is arranged at the bottom of the inner side of the softening tank at the position corresponding to the first softening foam plate. According to the method, through an output roller wheel, a hydraulic cylinder, a hot ironing device, an electret plate installation rack, an electret plate,and a high-pressure static generating needle which are matched with each other; when fibril flows through a first guiding roller wheel, the first guiding roller wheel is grounded via conducting wire,the high-pressure static generating needle can realize constant-temperature dual-pole corona electret on the fibril after fibril overlapping in the working process, so the fibril has restricting andsterilizing effects on common bacteria, the effect of single fibril can be effectively increased; and the method is applicable to filtering materials and the performance is more excellent.

Description

technical field [0001] The invention belongs to the technical field of composite fiber-wrapped yarn processing, and in particular relates to a composite fiber-wrapped yarn and a preparation method thereof. Background technique [0002] Composite fiber is a kind of multi-component fiber, which is a term for man-made fiber varieties. There are two or more polymer fibers that are not mixed on the same fiber section. This fiber is called a composite fiber, which is a physically modified fiber developed in the 1960s. Bicomponent fibers that combine the properties of both polymers can be obtained using composite fiber manufacturing techniques. There are composite fibers such as side-by-side type, sheath-core type, sea-island type, etc., and the fiber cross-section has round and irregular shapes. The fiber has three-dimensional crimp, high bulkiness and coverage, good conductivity, antistatic and flame retardancy. Composite fibers need to be spun on a composite spinning machine ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem of not being able to strengthen the superimposed fiber filaments, the effect of the composite fiber obtained after the combination is mostly provided by a single fiber filament. In order to achieve a certain effect, it needs more A variety of fiber filaments are likely to affect the thickness of the composite fiber, and in the process of stacking, the tension of the chemical fiber is likely to be insufficient, which leads to the problem of uneven stacking, and a composite fiber wrapping filament and its preparation method are proposed
