Two New Technologies For Regenerated Polyester Fiber Are Reviewed.

The new technology of "alkali oxygen one bath one step low temperature scouring and bleaching" of "regenerated polyester fiber and cotton blended fabric" and "two kinds of new technologies of regenerated polyester fiber and cotton blended fabric high wet rubbing fastness and crease free finishing" have been passed through the scientific and technological achievements of the provincial Science and technology office.

In order to improve Regenerated polyester And Cotton blended fabric The quality of dyeing and finishing, the Yilong printing and dyeing Co., Ltd., a self-supporting project, has gradually solved this technical problem. Starting from the basic principles and tasks of textile dyeing and finishing, the project analyzes the problems of the traditional three steps of desizing, boiling and bleaching, two steps of boiling and bleaching, and the problems of steaming with alkali oxygen, one bath, one step and 100 degrees. By using the self-made low temperature scouring agent YLLP, the alkali and oxygen one bath one-step process is used to pre treat and rinse the recycled polyester and cotton blended fabrics, and the semi finished products without stacking imprint are obtained. The whiteness, wool efficiency and strength are all consistent. dyeing Requirements. Compared with the traditional two step process, the new chemical process and the consumption of water and electricity obviously decreased, resulting in a marked reduction in production cost and a marked increase in economic efficiency.

On this basis, the team studied the "high wet rubbing fastness and crease free finishing of recycled polyester fiber and cotton blended fabric". Through a series of processes and auxiliaries improved, the product has reached the requirements of high-grade tooling fabrics, and expanded the scope of application of recycled polyester fibers. This result made the past simple and low-grade garment fabrics move towards high-end products. This is of great significance for organic recycling utilization of recycled polyester fiber waste products, reducing oil consumption, improving economic efficiency, and promoting the sustainable development of chemical fiber industry.

The results of the "China textile industry science and technology innovation and development strategy study (2016-2030)" released by 13 academicians and 130 experts in two years' completion of the key research project of the Chinese Academy of Engineering - "China's textile industry science and technology innovation and development strategy research" were released today. The results of the project point out that the technological level of China's textile industry is striving to be world-class in 2020, and reached the international leading position in 2030. It supports the transformation of the textile industry from labor intensive, resource consuming to technology intensive, resource-saving and environment-friendly, and achieving the "value oriented" strategic transformation.

The results of the project indicate that at present, China's textile industry has a weak capability of independent innovation, and some high-end products and equipment depend on imports. The integration of technology and equipment is relatively low. The creative design of clothing is still in the stage of imitation and imitation, with the low rate of localization of some high-end textile materials, the weak ability of collaborative innovation, the lack of investment and the shortage of talents, and the urgent need to form low-carbon green textiles in the whole life cycle. It is urgent to break through the bottleneck from big to strong through the continuous innovation of science and technology in textile industry.

The research group focuses on the theme of how to upgrade the technology of textile industry under the background of high-tech development. It focuses on the trend of high-end, diversified, intelligent, green, service-oriented and integrated development in the main fields of textile industry, as well as the realities and huge demands of the sustained development of urbanization, the continuous growth of residents' income, and the increasingly severe constraints of resources and environment. It also proposes a general roadmap of goals, tasks and comprehensive development from basic research to key technologies to industrial applications, as well as the roadmap for innovation and development in various fields of technology.

Yu Jianyong, academician and vice president of the Chinese Academy of engineering, told reporters that the technological innovation roadmap of China's textile industry is divided into two stages, one is the development of "13th Five-Year", and the other is for the future development in 2030. Around the industrial chain, there are two major support from the aspects of new fiber materials, advanced textile processing technology, ecological dyeing and finishing technology, modern garment processing technology, industrial textile technology and so on: first, the high-end equipment manufacturing; two, the information technology of the industrial chain and the economic and trade management technology of the textile industry, to explore the scientific and technological innovation ideas based on the new format.
