Abstract：Fine bubbles,as a green and environmentally friendly cleaning technology,are used to clean oil stains on the surface of textiles.The cleaning efficiency of ultrafine bubbles was evaluated based on the weight method and whiteness method,using polyester as the textile substrate and soybean oil and lubricating oil as the oil stains,which were stained with Sudan Red.The results show that compared with tap water,the cleaning efficiency of ultrafine bubble water for surface oil stains is higher.For example,for soybean oil,the removal rate of ultrafine bubble water is 29.84%,while that of tap water is only 9.21%.The main functions of ultrafine bubbles in removing surface oil stains are the fragmentation of micro-jets and adsorption.Comparing the effects of stagnant bubble water and newly generated bubble water on the removal of surface oil stains,the fragmentation micro-jet and upward movement of micron-sized bubbles are more conducive to the removal of surface oil stains than the adsorption and surface charge repulsion of ultrafine bubbles.
