“Currently, due to geopolitical changes intertwined with the impact of the COVID-19 epidemic, the ‘triple pressures’ have superimposed unexpected changes, and the textile industry is under great negative pressure and is in a critical window for transformation. The conflict between Russia and Ukraine has led to an increase in corporate energy costs and production costs. With the market downturn and insufficient orders, the pressure on foreign trade exports can be imagined.” Zhen Zhongming, secretary of the party committee and chairman of Yixing Leqi Textile Group Co., Ltd., said that in order to effectively resolve the impact of many uncertain factors On the one hand, Leqi Group has increased its product research and development capabilities, opened up new markets and new products, and shifted from mainly export sales to both domestic and foreign sales; on the other hand, it has actively created a unified digital platform to accelerate digitalization, informatization, greening and low-carbon transformation. , greatly enhancing the competitiveness of enterprises.

From January to June, Leqi Group’s product sales revenue was 1.64 billion yuan, basically the same as the same period last year. Among them, self-import and export amounted to US$113 million, an increase of 34% over the same period last year.

For more than 30 years, Leqi Group has always adhered to the development concept of “building reputation together and having fun”, and is committed to becoming a stop for global customers to provide R&D and manufacturing of mid-to-high-end fabrics with an annual output of 100 million meters. A professional manufacturing enterprise with full-service services, focusing on customizing mid-to-high-end, multi-fiber, super-soft and high-elastic, functional, business, sports and leisure, outdoor, workwear and other fabrics for domestic and foreign brands, with an annual production of 120 million meters of various fabrics and 500,000 garments. With more than 100 pieces, it has become the largest production base of pure cotton and blended interwoven fabrics in China, and is a material procurement supplier for the Logistics Support Department of the Central Military Commission, the Ministry of Public Security, and the State Administration of Taxation. It has successively won the titles of “Top 30 in China’s Printing and Dyeing Industry”, “China’s Quality Integrity Enterprise”, “Excellent Enterprise in Energy Saving and Emission Reduction in China’s Printing and Dyeing Industry”, “National Textile Industry’s Advanced Party Building Work Demonstration Enterprise”, “China’s Textile Brand Cultural Innovation Award” and “China’s Textile and Apparel Enterprise Competition”. It has won many honorary titles such as “Top 500 Enterprise in Jiangsu Province”, “High-tech Enterprise in Jiangsu Province”, “International Famous Brand Keyly Cultivated and Developed in Jiangsu Province”. “Leqi” brand printing and dyeing fabrics have won the exemption certificate and national product quality inspection exemption.

Implementing dual carbon goals

Green Leqi in action

In 2020, the country clearly proposed that “carbon peak” in 2030 and “carbon neutrality” in 2060 With the goal of “and”, “double carbon” has been officially written into the 2021 government work report. In order to achieve green and high-quality development, Leqi Group has carried out a series of green improvements and integrated innovations in the whole process and in all aspects, focusing on green factories, green products, green product design, green supply chain, green production, green packaging, green transportation, etc. , started the battle for green transformation and upgrading.

“In today’s global warming situation, all sectors of society pay more attention to the unification of economic development goals and ecological civilization construction, and advocate the harmonious coexistence of man and nature. Printing and dyeing, as a high energy consumption and high pollution industry, how to produce Energy conservation and emission reduction in the process are the focus of the current work, and the development of green printing and dyeing has become an industry consensus.” Zhen Zhongming said that in order to follow the road of green, low-carbon and sustainable development, Leqi Group has always improved its energy conservation and emission reduction work over the years. At the level of the company’s important development strategy, with energy conservation and efficiency, waste control and emission standards as its two wings, we will use the progress of science and technology to inject independent innovation vitality, and form a powerful driving engine through the integration of automation and informatization platforms to achieve leapfrog development and rapid development. Promote various energy use management and make important contributions to the economic growth of enterprises.

In this regard, Leqi Group has invested a lot of manpower and financial resources and carried out a series of technological transformations based on the principle of energy conservation and consumption reduction. It has successively implemented an ozone advanced oxidation decolorization reclaimed water system; MVR (mechanical recompression technology) alkali recovery technology; a new 4,000 tons/day; sewage advanced treatment system; the use of CO2 to replace mineral acid neutralization; and the efficient steam system Utilization technology transformation; carbon dioxide sewage PH value adjustment technology; solar power generation project high-pressure steam back pressure grid-connected power generation project; workshop steam remote distributed automation control (DCS) project; dryer barrel drain renovation project; dryer automation infrared Temperature control steam-saving project; machine high-temperature sewage two-stage heat exchange project; mercerized light alkali membrane ultrafiltration purification and reuse project; dyed brine decolorization and reuse project; automation and informatization integration data online acquisition and control system; sewage treatment plant A large number of key energy-saving and emission-reduction projects including raising emission standards, solid waste treatment, and exhaust gas purification treatment. It has successively won the honorary titles of Jiangsu Province Clean and Civilized Production Enterprise, Environmental Protection Green Enterprise, etc., and won the Enterprise Excellence Award in the National Energy Saving and Emission Reduction Standard Competition in the national printing and dyeing industry.

Solar photovoltaic power generation is 3.5 million kilowatt hours/year; steam waste heat power generation is 12 million kilowatt hours/year; the air compressor is decommissioned and compressed air is commercialized, saving approximately 12 million kilowatt hours of electricity every year; sewage By replacing the energy-saving jet heads, the electricity consumption is about 840,000 kilowatt-hours/year… Behind the dazzling numbers is the commitment of Leqi people to fulfill the “dual carbon” commitment.

“It can be said that by using technological innovation to change production methods, Leqi Group has implemented energy conservation and consumption reduction in every link, effectively realizing the green development of the enterprise.” Zhen Zhongming said that in the next 3-5 years, Leqi Group plans to adopt international new dyeing technology and automated material systems, which are expected to save 50% of electricity, 60% of steam, and 70% of water. Especially during the “14th Five-Year Plan” and “15th Five-Year Plan”, we will also develop according to our own development.According to the current situation, the government has formulated various development plans to make energy clean and low-carbon, and make due contributions of Leqi people to achieve the “double carbon” goal.
