    摘要: Textile materials are treated with an alkaline aqueous medium having a pH value of 7.5-11 and containing 0.25-4% by weight of a dissolved water soluble hydrophilic soil release polymer having carboxylic acid groups and 0.05-1% by weight of a dispersed hydrophobic soil repellent fluorochemical. The soil release polymer and the soil repellent fluorochemical are deposited on the surfaces of the textile fibers and the resulting textile material is dried to impart the desired nondurable soil release and soil repellency properties. The aqueous medium also may contain polyvinylpyrrolidone to further improve the finish. In a preferred variant, the textile material is first contacted with an alkaline aqueous solution of the soil release polymer, and thereafter with an alkaline aqueous medium containing the dispersed soil repellent fluorochemical to reduce the tendency of the deposited soil release polymer to cover the deposited soil repellent fluorochemical molecules. A method of laundering soiled textile material is also provided wherein the washed and rinsed textile material is treated in accordance with the aforementioned method to impart nondurable soil release and soil repellency properties. The treated textile material is provided as a novel product.
