Early Exploration and Initial Development
The development of Western textile auxiliaries can be traced back to the late 19th and early 20th centuries. In 1870, German scientists successfully synthesized turkey red oil (sulfated castor oil), considered the first synthesized textile auxiliary. Due to its resistance to hard water and acids, and its cleaning, emulsifying, and dispersing properties, it was quickly applied in the textile industry. Subsequently, in 1917, the German company BASF synthesized a surfactant commercially known as Zeikar-A using butylnaphthalene refined from coal tar as a raw material, further promoting the development of textile auxiliaries.

Post-World War II Technological Innovation and Industrial Expansion
After World War II, with the rapid development of petrochemical and organic synthesis technologies, the textile auxiliary industry experienced unprecedented growth. New varieties emerged in an endless stream, and technologies continued to innovate. Industrialized countries such as Germany, the United States, and the United Kingdom increased investment, promoting the development of textile auxiliaries towards high efficiency, multifunctionality, and environmental friendliness. During this period, textile auxiliaries not only increased significantly in quantity but also achieved a qualitative leap in quality, meeting the textile industry's demand for high-quality, high-performance auxiliaries.

Globalization and Market Expansion
In the late 20th century, as the global textile industry shifted to Southeast Asia and other regions, Western textile auxiliaries companies actively adjusted their strategies, consolidating their leading positions through globalization and market expansion. Well-known companies such as the German Rudolf Chemical Group, leveraging their strong R&D capabilities and high-quality products and services, established comprehensive sales networks and production bases worldwide, becoming leaders in the textile auxiliaries industry.
