Our factory was established in 1980 as a dye chemical production enterprise integrating research, production, and operation. With a history of 26 years, we specialize in manufacturing acid dyes, mordant dyes, and dye intermediates. Our current assets exceed 20 million RMB, with an annual production capacity of 1,000 tons. Our registered trademark is "Wenyou" brand, and we have been recognized by the Jiangsu Provincial Quality Supervision Bureau as a "Quality-Focused and Trustworthy" unit.

The R&D department consists of 6 senior engineers (including 2 foreign experts), 6 engineers, and 10 technicians, responsible for the development of new products. Our self-developed Acid Blue HRL (C.I Acid Blue 182) meets world-class quality standards and has received the Jiangsu Provincial "Golden Bull" Award for new products. New mordant dye varieties include Mordant Red 9# (C.I Mordant Red 9) and Mordant Brown KE (C.I Mordant Brown 15). New direct dye varieties such as Violet No. 9 and Violet No. 51 are among the earliest produced domestically. We maintain long-term collaborative relationships with Shenyang Chemical Research Institute and Shanghai Dyestuffs Research Institute, ensuring strong technical capabilities and rapid new product development.

The production department operates nine workshops with complete water, electricity, and steam facilities. It includes three 150,000 kcal refrigeration units capable of producing ice water and ice blocks, nearly 100 enamel reaction kettles ranging from 1,000L to 5,000L, and downstream equipment for drying, blending, and packaging. The factory is equipped with automated wastewater treatment facilities for chemical production, with treated water quality meeting national discharge standards. The sales company handles both domestic and international product distribution. Our products are directly supplied to wool textile mills and dye chemical companies across China. We maintain longstanding business relationships with import and export companies in Shanghai, Hebei, Tianjin, Qingdao, Zhejiang, Ningbo, Hainan, Shenzhen, Jiangsu, Wuxi, and others. Our products are exported to Japan, the United States, the United Kingdom, Germany, Egypt, South Korea, and other countries and regions, with exports accounting for 80% of our production volume.

We look forward to collaborating with more clients to create a brighter future for the dye industry!
