Cationic dacron composite double-color-effect fibers and preparation method of cationic dacron composite double-color-effect fibers

Abstract

The invention discloses cationic dacron composite double-color-effect polyester fibers. The cationic dacron composite double-color-effect polyester fibers are formed by compounding a polyester fiber and a cationic polyester fiber at a ratio, wherein the polyester fiber and the cationic polyester fiber are in a double-spiral shape and are compounded together through network points; the distance between the network points is 5mm to 100mm and the unit length of double spirals is 10mm to 200mm. The invention further discloses a preparation method of the cationic dacron composite double-color-effect polyester fibers. The preparation method comprises the following steps: selecting pre-orientated polyester fibers and pre-orientated cationic polyester fibers according to the ratio; drafting, falsely twisting, compounding, adding a network by a nozzle, heat setting, and winding and molding to obtain the cationic dacron composite double-color-effect polyester fibers. The cationic dacron composite double-color-effect polyester fibers disclosed by the invention have the characteristics of abundant color changes, diversified styles, wide application range and the like.

Description

technical field [0001] The invention relates to a chemical fiber and a preparation method thereof, in particular to a cationic composite double-color effect polyester fiber and a preparation method thereof. Background technique [0002] With the development of society and the advancement of science and technology, people's demand for clothing is no longer just to keep warm, but to pay more attention to the beauty of clothing. The traditional single-tone and monotonous-style fabrics can no longer satisfy people's pursuit of the beauty of clothing fabrics. It is urgent to seek rich color changes. , and diverse styles of fabrics, so people began to explore the blending of different natural fibers, the blending of natural fibers and chemical fibers, and the blending of different chemical fibers to achieve changes in fabric color and style, but this production method has many processes and a long process. Production costs are high. Chemical fibers are the first choice for develo...
