A method of forming composite filaments

Abstract

The invention relates to the technical field of spinning, in particular to a method for forming composite filaments. The method uses a production device for forming composite filaments, the production device includes a plurality of spinnerets, a heating device, a first heating roll, a second heating roll, etc., wherein the heating device can heat the filament bundle unevenly, the The heating device includes a plurality of guide wheels, a first caterpillar, a second caterpillar, a plurality of heating pipes located on the crawler belts, a heat pipe device fixing block for fixing the heating pipes, and the like. The heating device is convenient to assemble, easy to produce, and low in cost. The production device of the present invention adopts this heating device. Compared with the traditional spinning composite yarn production device, it has low production cost, and the thickness and detail size and spacing distance of the slub filaments in the composite yarn can be adjusted. At the same time, it can also produce It has the advantages of brilliant and colorful composite wire.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a production device and method for forming composite filaments. Background technique [0002] Now, with the improvement of living standards, people's requirements for clothing fabrics are also getting higher and higher. People are no longer satisfied with ordinary fabrics, but emphasize individuality. There are many chemical fiber fabrics on the market now, and these chemical fiber fabrics have various styles. However, some consumers like the fabrics and functions of imitation hemp and wool. Nowadays, there is already a kind of slub yarn on the market, which can make the slub yarn not only have the characteristics of orderly and uniform distribution in appearance, but also have the difference in linear density and the style of "imitation bamboo knot", and also have differential dyeing , good moisture absorption and air permeability, strong unevenness and other properties. Th...

Problems solved by technology

However, according to the patent embodiment, it can be seen that the positions of the heating zone and the non-heating zone on the first heat roller are relatively fixed, and the distance between the heating zone and the non-heating zone cannot be adjusted, and the distance between the coarse and fine details cannot be adjusted. At the same time, the temperature of each heating zone is the same, and the differential heating of each heating zone cannot be realized.
