The development history of foreign waterproof and oil repellent agents

People use silicone to post-finish fabrics, which can only give the fabric water resistance.

In 1950, DuPont of the United States patented the use of tetrafluoroethylene emulsion as a water- and oil-blocking agent for fabrics; in 1952, 3M Company of the United States developed a fabric finishing agent with chromium perfluoroxitate complex as the main component. It was replaced by the Scotchguard series of fluorine-containing acrylic fabric finishing agents with better performance; in the 1960s, Japan and Western Europe also successfully developed similar products; in the 1970s, research types showed diversity, such as organofluorine-modified polybutylene olefin, silicone-containing organic fluorine water-blocking and oil-proofing agent, fluorine-containing polyurethane, etc.; due to environmental protection requirements in the 1980s, the German Hoechst Company developed a water-soluble fluorinated polyurethane water-blocking and oil-proofing agent. This product is environmentally friendly It is less harmful to the human body and has lower cost; the Asahi Guard fluorine water and oil repellent agent developed by Japan’s Daikin Industrial Co., Ltd. in the 1990s has low-temperature baking properties. At present, the major international companies that produce water-proof and oil-proof products and their product names are: Teflon from DuPont in the United States, Scotchguard from the American 3M Company, Asahi Glass AG from Japan, and Daikin Union.
