Zhang Fang Jun, director of science and Technology Department of CSPC, chaired the meeting. 6 scientific and technological achievements related to knitting related digital manufacturing and green processing were introduced at the meeting.

Sun Hong said in his speech that as a famous city of socks industry in China, Liaoyuan has unique deep feelings and good expectations for the development of the industry of textile socks.

After more than ten years of exploration and practice, relying on traditional industries such as light industry and textile industry, Liaoyuan has been focusing on the textile and socks industry.

Especially in the past two years, we have firmly grasped the strategic opportunity to revitalize the old industrial base in the northeast, and promoted the development of the scale, park and high-end of the textile and socks industry. The industrial scale has taken the lead in the whole country, forming a pattern of stockings in the South with Zhuji and Liaoyuan in the north.

In the next five years, Liaoyuan will firmly grasp the policy opportunities of national support for the development of socks industry, actively undertake industrial pfer in developed areas, and promote the coordinated development of online and offline industries with the help of "Internet +" and "big data plus". We will expand the brand strength and speed up the global influence and market share of Liaoyuan socks industry, and actively build the largest eco cotton socks production base in China. The broad prospect of Liaoyuan socks industry is worth looking forward to.

She hopes that domestic industry elite, entrepreneurial talents and investment merchants will pay close attention to Liaoyuan and settle down in Liaoyuan and work together to create a bright future for the development of China's socks industry.

In his speech, Ye Zhimin said that the dissemination of key scientific and technological achievements of "textile light" is the textile industry's public welfare technology promotion activities set up by the textile optical technology education foundation since 2011.

The foundation has jointly held 42 promotional sessions with the China spin alliance science and technology department and the China Textile Federation sub trade association, which plays an important role in accelerating the pformation of textile science and technology achievements into real productive forces.

However, there are still problems in the application of scientific and technological achievements in the industry, such as many achievements in science and technology in Textile Universities, but many achievements can not be converted. Some common technologies that lead the development of the industry have not been publicizing and applying in a wider range of enterprises.

Therefore, accelerating the pformation of scientific and technological achievements into real productive forces is an important task for the industry at present.

He hoped that this event could benefit more industry enterprises and play a positive role in supporting enterprises to develop new products, improve product quality, improve production and operation efficiency, and improve economic efficiency of enterprises.

Gao Yong issued the donation certificate for "textile light" to the Northeast hosiery textile industrial park.

Key technology 1: technology and equipment of digital automatic dyeing of cheese yarn

Fan Aihong, sales director, Shandong Kangping Group Machinery Co., Ltd.

Cheese dyeing has four main problems: low efficiency in labour intensive production, poor stability in dyeing quality, high energy consumption, large amount of wastewater discharge and poor working environment.

The best way to solve this problem is to build an intelligent dyeing factory to achieve the crossing of manual dyeing, single machine automation, whole process digitalization and system automation.

Taking the intelligent dyeing factory with an annual output of 20 thousand tons of cheese as an example, saving 1 million 900 thousand tons and saving 24 million kilowatt hours saves 114 thousand tons of steam and reduces 1 million 800 thousand tons of wastewater discharge.

Kangping Nana plan to establish 50 intelligent dyeing factories throughout the country, which can achieve 95 million tons of water saving, 90 million tons of sewage discharge, 889 thousand tons of standard coal for annual energy consumption, and remarkable environmental protection benefits.

Key technology two: hemp fiber functionality and high quality knitwear development

Key technology three: high quality hemp spinning technology and Application

Gao Mingzhai, deputy general manager of Wuhan hemp Biotechnology Co., Ltd.

At present, there are three key technologies for hemp spinning, one is the technology of double cleaning and double comb spinning of hemp fiber. After mixing the hemp fiber and cotton fiber (after combing), the combing process is no longer necessary to reduce the cost of the traditional spinning process by more than 20%.

The two is hemp compact Siro spinning technology, which is applied to pure cotton, viscose and other pure spinning and blended yarns.

The three is hemp fiber spinning technology, which can greatly improve the quality index of the same kind of yarn and reduce the grade of raw material cotton blending.

Key technology four: characteristics and application of differential nylon staple in socks industry

Zhao Ling, chairman of Wuxi Textile Co., Ltd.

Nylon has good wear resistance, and the first place to have fiber is 10 times of cotton, 20 times of wool and 140 times of wet viscose fiber.

The strength is 1-2 times higher than that of cotton and 3 times that of viscose fiber.

The reasons why nylon staple fiber is less used in textile industry are: the dependence degree of raw materials has been high for a long time, and the raw materials of short fiber are mainly recycled; upstream staple manufacturers lack market promotion, research and development personnel;

The technical terminal is difficult, and the terminal industry chain of the downstream reaches no understanding of nylon staple.

Nylon is widely used in socks at present. The key to solve the pain problem is broken holes, smelly feet, sweat feet, poor skin affinity, etc.

High strength nylon short fiber produced by special technology and equipment has high breaking strength of 6.5cN/dtex, which can greatly improve the breaking strength of blended yarn.

Breaking strength and tear force.
