Not long ago, the market was concerned about the toxic incident of Teflon non-stick pans. The culprit was perfluorooctaneAmmoniumC7F15C00-NH4+), which reminds people that water-repellent and oil-repellent finishing agents also contain perfluorooctyl components. Since eight-carbon fluorocarbons are organic compounds that are difficult to biodegrade, they are seriously harmful to human health and the environment. The European Union banned PFOS (Per-fluorooctaneSulfonate, C8Fl7SO3-K+) on December 27, 2006. In fact, around 2002, the U.S. Environmental Protection Agency (EPA) detected PEOA in the blood of wild animals and humans, and published a preliminary risk report on the safety and quality of PFOA and PFOS in March 2003. On January 25, 2006, all fluororesin, fluorine-containing water-repellent, and oil-repellent finishing agent manufacturers were required to participate in a plan to reduce the emissions of PFOA, PFOS and their related substances, and to reduce the PFOA and PFOS content in their products. Each manufacturer is required to reduce the production to 5% of the 2000 level by 2010, and to no longer produce and use PFOA and PFOS by 2015.

Fluorine-containing water- and oil-repellent finishing agents are mainly used to produce water-repellent, oil-repellent and anti-fouling (three-proof) finishing textiles, as well as some easy-to-decontaminate finishing textiles. This type of finishing fabric is used to make high-end women’s and men’s outerwear, such as windbreakers, casual wear, protective work clothes, as well as high-end tablecloths and light tents. There is no complete statistical data on my country’s annual consumption of fluorine-containing finishing agents. Relevant experts estimate that it is about 11,000 tons, of which more than 95% is imported. This can produce approximately 100 million m2 of water- and oil-repellent finishing fabrics. about. Some of them are made into clothing and exported to the European and American markets. These products were sampled and tested according to the quality standards required by customers and the main functional indicators. The average failure rate in 2006 was 6.86% (including 24,630 times waterproof, 24,370 times water-repellent, and 8,230 times oil-repellent). times and anti-contamination 9340 times), which basically reflects the overall level of water-repellent, stain-repellent and easy-to-decontaminate finishing products produced in my country.

As for the water-repellent, oil-repellent and easy-to-decontaminate finishing after 2015, it depends on the research on the replacement of low-carbon (C4~C6) fluorocarbon compounds, as well as the enlightenment of the lotus leaf effect and the combination with dendrimers (Dentrimer) or Research progress on the effects of other nanomaterials and other composites.

It is worth noting that some literature reports that PFOS pollution is widespread in my country’s water environment. The surface water pollution in Shanghai is more serious than that in foreign cities, while the pollution of the Huangpu River water (PFOA1584.83ng/L, PFOS20.43ng/L) is much higher. higher than the Yangtze River water.

The C4-C6 waterproof and oil-proof finishing agent produced and distributed is environmentally friendly and low-carbon, does not contain PFOA, PFOS, and APEO, and can meet the standard requirements of OEKO-TEX100, which is worthy of attention.
