Problems solved by technology

[0002] With the continuous improvement of science and technology, people's living standards are also continuously improved, which leads to the increase of people's requirements for the fabrics they wear. As a common fabric in fabrics, polyester has the biggest advantage of wrinkle resistance. Therefore, most polyester fibers are currently used to make clothing jackets, which has led to a substantial increase in the strength of polyester fibers, so the strength of traditional polyester fibers can no longer meet the needs of today's people.
In addition, the existing colored coated fiber in China has a monofilament fineness of more than 1dpf, and the softness, drapability, adsorption, decontamination, filterability, and waterproof and breathable properties of the yarn and fabric cannot meet the needs of high-end fabrics. And the requirements of special field applications limit the development speed of new products to a large extent, and also produce waste water to pollute the environment during the dyeing process, and the color is uneven, color rendering, chromatogram and color fastness are poor

Abstract

The invention provides a preparation process of polyester fibers. The preparation process includes the steps of: 1) preparing the following raw materials including: 70-75 parts of organic binary acid, 25-30 parts of dihydric alcohol, 50-60 parts of polyamide fibers, 40-50 parts of protein fibers, and 1-5 parts of a color master batch; 2) performing a condensation polymerization to the organic binary acid and the dihydric alcohol in a high-temperature electric furnace, drying the polyamide fibers, the protein fibers and the color master batch through a drying machine, and crushing the dried mixture to obtain a mixture material; 3) after the condensation polymerization is completed, adding the mixture material into the high-temperature electric furnace to perform high-temperature fusion to obtain a melt mixture; 4) spinning the melt mixture; 5) cooling and water-washing a spinning tow and drafting the spinning tow through a drafting machine; 6) thermal-shaping the spinning tow; and 7) cooling and shaping the spinning tow to obtain a final product. The polyester fiber has uniform color, is high in color fastness and is high in strength.

Description

Technical field [0001] The invention relates to the technical field of clothing raw material processing, in particular to a preparation process of polyester fiber. Background technique [0002] With the continuous improvement of science and technology, people's living standards have also been continuously improved, which has led to an increase in people's requirements for the fabrics they wear. As a more common fabric in the fabric, the biggest advantage of polyester is wrinkle resistance. And the shape retention is very good. Therefore, currently polyester fibers are mostly used to make clothing jackets, which has led to a substantial increase in people's requirements for the strength of polyester fibers. Therefore, the strength performance of traditional polyester fibers can no longer satisfy people nowadays. In addition, the current domestic colored coated fiber has a monofilament size of more than 1dpf, and the softness, drape, adsorption, decontamination, filterability, and ...
