Problems solved by technology

At present, a large number of new varieties of black dyes have been successfully synthesized, and some breakthroughs have been made in the dye compounding technology to improve the performance of black dyes. However, these are all synthetic dyes. Synthetic dyes contain certain harmful substances that will affect health. The printing and dyeing process is complex, and a large amount of wastewater will be generated during the printing and dyeing process, causing industrial pollution and industrial waste.

Abstract

The invention provides a composite covered yarn and a preparation method thereof. The composite covered yarn comprises a core yarn and an outer covering yarn. The core yarn is a spandex filament, theouter covering yarn comprises a kapok fiber yarn and a flax fiber yarn, the kapok fiber yarn winds around the surface of the spandex filament, the flax fiber yarn winds around the outside of the kapokfiber yarn, and winding directions of the kapok fiber yarn and the flax fiber yarn are opposite; the kapok fiber yarn and the flax fiber yarn are dyed black by adopting environmentally friendly dye liquor. According to the composite covered yarn, the kapok fiber yarn and the flax fiber yarn are adopted by the outer covering yarn, and a dyeing manner of combination of vegetable dye and carbon black is adopted, so that the composite covered yarn has the advantages of being good in compatibility, free from toxic and pollution and friendly to environment, the composite covered yarn is healthy andhas better biodegradability, technology of dyeing process is simple, and dyeing is uniform.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a composite covered yarn and a preparation method thereof. Background technique [0002] Covered yarn is a new type of yarn structure, which uses filament or short fiber as the yarn core, and another filament or short fiber sliver is outsourced. Covered yarn is widely used in the production of high-grade underwear, stockings, jeans, high-grade suit fabrics, and other products. [0003] The dyeing of covered yarn needs to be carried out by dyes, and black dyes play an important role in textile printing and dyeing. The early black dyes are mainly azo dyes derived from benzidine, which have the advantages of good blackness, high dyeing rate and color fixation rate, but the carcinogenic intermediate benzidine will be released during production and use. At present, a large number of new varieties of black dyes have been successfully synthesized, and some breakthroughs h...
