[Analysis] Technical level and technical characteristics of the domestic color spinning industry


Although China’s textile industry’s production capacity has occupied the first place in the world for many years, China’s textile fiber resources are limited, and the tasks of energy saving, emission reduction, consumption reduction, and reduction of environmental pollution are heavy. At the same time, international apparel and home textile products have entered a new era of ecology, safety, and health care. All these have imposed higher requirements on China's traditional textile industry, and require the entire industry to take scientific and technological innovation as an entry point to study this series of issues and pay for them. Implementations. At present, with the wide application of information technology, the continuous improvement of the level of textile machinery, mechanical and electrical integration, the introduction and learning of foreign advanced equipment, the overall technical level of the textile industry has been continuously improved.

Color spinning, as a fine-molecule industry in the textile industry, has shortened the production process of follow-up processing companies by adopting the new technology of “first dyeing and after-spinning” compared with the traditional process of “first spinning and post-dyeing”. , Lower production costs, have higher added value, especially to solve the problem of large pollution in the traditional dyeing and finishing industry in a breakthrough manner, which greatly reduces energy consumption and environmental damage. Color spinning yarns are generally mixed and spun into two or more different color fibers or fibers with different properties. This process is mainly a physical mixing process. Yarn spun yarns are rich in color, clear in layers, strong in three-dimensional color, and have good consistency in shade. After weaving into a cloth, the fabric presents a multi-colored, soft-feeling, full-featured appearance.

The core technologies in the color spinning industry are mainly reflected in the aspects of sewage treatment, energy conservation and emission reduction, cotton fiber dyeing and new species development. If you want to occupy a place in the color spinning industry, the above three points on the technical level must be solved.

In the aspect of sewage treatment, energy conservation and emission reduction, dyes remaining in industrial wastewater need to be processed through various physical and biochemical technologies to meet relevant national standards; in terms of cotton fiber dyeing, how to solve the problem of color difference and how to improve the color fastness, The control of the regain rate is its main core link; in the development of new varieties, it tests the ability of enterprises to accurately grasp the market demand, utilize new technologies and new concepts, and continuously launch new products that meet market trends.
