Background

At present, a water-proof and oil-proof agent, also called a three-proof finishing agent, is a post-finishing agent suitable for most textile fabrics, wherein most of the post-finishing agent takes a fluorine-containing acrylate polymer as a main effective component. The organic fluorine three-proofing fabric finishing agent is prepared from a perfluorooctyl sulfophthalein compound, perfluorooctanoic acid or other perfluoroalkyl compounds containing eight or even longer carbon chains. However, these compounds are extremely difficult to decompose in the environment, easily accumulate in the living body, and have health effects on the human body

In addition, at present, the number of the invading foreign organisms in China is 544, more than 100 invaded foreign organisms which occur in a large area and are seriously harmful are generated, and the invading foreign organisms cause direct economic loss of more than 570 million yuan per year to China while seriously affecting the ecological environment. Taking water hyacinth as an example, the salvage cost is 1 million yuan each year, and chemical control is also thousands of yuan. The existence of the foreign invasive plants also challenges the ecological balance, so people turn the harmful plants into valuables, some of the plants are used as feed, some of the plants are used as medicinal materials, and some of the plants are used for extracting dyes. However, reports on the application of the biomass-derived.
