Crafting Premium Dyes with Ingenuity—Zhongsheng New Technology Leads the Way in Green Chemistry

In the Zhongwei Industrial Park of Ningxia, a national-level high-tech enterprise that has been deeply engaged in the dyes and intermediates sector for nearly three decades is writing a vivid chapter in the green transformation of China's fine chemical industry, powered by technological innovation. Since its establishment in 1998, Ningxia Zhongsheng New Technology Co., Ltd. has evolved from its initial mixed-ownership structure into a globally leading professional producer of deep blue reducing agents, and with its outstanding industry position and forward-looking strategic planning, is steadily advancing toward its goal of becoming a world-class integrated dye service provider.

Profound Heritage, Innovation-Driven Excellence Sets Industry Benchmarks

As one of the earliest investment-attraction enterprises in Zhongwei City, Ningxia Zhongsheng New Technology relocated to the Zhongwei Industrial Park in 2014 due to industrial policy adjustments. The company now occupies 688 mu (approximately 45.9 hectares) of land, employs over 500 staff, and achieved an industrial output value of 768 million RMB in 2023. Guided by the philosophy of "Striving for excellence in quality, driving development through technological innovation," the company has been recognized as a National High-Tech Enterprise and a Specialized and Sophisticated Enterprise of the Autonomous Region. It has also established the Ningxia Engineering Research Center for Acid-Containing Wastewater Treatment and the Ningxia Engineering Research Center for Green and Environmentally Friendly Dyes. Through sustained independent R&D and industry-university collaboration, the company has filed over 50 patent applications and achieved more than 30 innovative scientific and technological achievements, including several major accomplishments at both national and autonomous-region levels.

Core Products, Dominating Global Niche Markets

The company's product portfolio comprises two core pillars: dye intermediates and environmentally friendly disperse dyes, covering raw material needs across textiles, pharmaceuticals, and agrochemicals.

1. Deep Blue Reducing Agent Series (Global Flagship Core Product)

The core competitiveness of Ningxia Zhongsheng New Technology is rooted in the global dominance of its flagship product— Deep Blue Reducing Agent (2-Amino-4-acetaminoanisole) . This product is a key intermediate in the production of dyes, pharmaceuticals, and pesticides. The company employs a self-developed clean and efficient catalytic hydrogenation reduction process, which replaces the traditional iron powder reduction method and fundamentally eliminates the pollution issue of iron sludge waste. Currently, the company has an annual production capacity of 20,000 tons of reducing agent, ranking first in China and capturing approximately 65% of the global market share—truly a "hidden champion" in its niche segment. Supporting derivative intermediates include 2-nitro-4-acetaminoanisole, p-anisidine, and 6-chloro-2,4-dinitroaniline, featuring stable purity and controllable impurity levels that meet high-end dye synthesis standards.

2. Green Liquid/Powder Disperse Dye Series

Leveraging its intermediate advantages, the company is vigorously expanding downstream into end products, forming a product matrix anchored by three pillars: reducing agents, hexachloro compounds, and dyes. It has independently developed ultra-clean liquid disperse dyes and environmentally friendly filter-cake dyes, covering a full color spectrum including Disperse Black, Disperse Dark Blue, Disperse Brilliant Red, Rubine, and Orange (models such as ZX-GS300%, ZX-2GF200%, HGL200%, and EX-SF300%). These products are suitable for high-temperature, high-pressure dyeing and printing of polyester and blended fabrics, featuring high dye uptake, high sublimation fastness, low dust emission, and low residual liquid discharge. The liquid dyes require no grinding, significantly reducing downstream processing energy consumption, aligning with the textile industry's low-carbon transformation needs, and delivering tangible energy savings, emission reduction, and cost-efficiency benefits for customers.

Technology Leadership, Dual-Driven by Green and Safe Operations

Technological innovation and green safety are the twin engines driving the development of Ningxia Zhongsheng New Technology. On the technology front, the synthesis yields and product quality of the company's flagship products have reached industry-leading levels. On the environmental protection and safety front, the company has made substantial investments, constructing a series of facilities including activated carbon regeneration units, MVR desalination systems, and hazardous waste incinerators, achieving comprehensive resource utilization of the "three wastes" (wastewater, exhaust gas, and solid waste) and fundamentally resolving environmental challenges in dye production. The company has not only attained the Autonomous Region's Level 2 Work Safety Standardization certification but has also established a professional in-house fire brigade, deployed personnel positioning systems, and implemented an Internet-plus work safety information platform, achieving over 3,500 consecutive days of accident-free production.

Global Vision, Advancing Toward a Green Integrated Service Provider

Currently, Ningxia Zhongsheng New Technology's products are exported to numerous countries and regions, including India, Pakistan, Vietnam, and Turkey, with trademark registrations completed in eight countries. To further strengthen its industrial chain, the company has invested 580 million RMB in a 28,000-ton-per-year green and environmentally friendly dye production project, which has now commenced operations. Upon reaching full capacity, the project is expected to generate annual sales revenue of 1.5 billion RMB and create over 800 job opportunities.

Staying true to its founding mission of "Protecting the Environment, Driving Innovation Through Science and Technology" within the green fine chemical sector, Ningxia Zhongsheng New Technology will continue to expand its reactive and acid dye production lines, deepen R&D into low-carbon, salt-free novel dyes, and upgrade its digital service systems. Leveraging its leading intermediate production capacity and environmental technology advantages, the company remains committed to empowering the global textile dyeing and printing industry's green transformation, and strives to become a globally trusted integrated supplier of dye raw materials.
