Abstract: The invention provides a method and formulation for cleaning a soiled substrate, the method comprising the treatment of the moistened substrate with a formulation comprising a multiplicity of polymeric particles, wherein the formulation is free of organic solvents. Preferably, the substrate is wetted so as to achieve a substrate to water ratio of between 1:0.1 to 1:5 w/w. Optionally, the formulation additionally comprises at least one cleaning material and, in this embodiment, it is preferred that the polymeric particles are coated with the at least one cleaning material. Preferably, the cleaning material comprises a surfactant, which most preferably has detergent properties. Most preferably, the substrate comprises a textile fiber. Typically, the polymeric particles comprise particles of nylon, most preferably in the form of nylon chips. The results obtained are very much in line with those observed when carrying out conventional dry cleaning processes and the method provides the significant advantage that the use of solvents, with all the attendant drawbacks in terms of cost and environmental considerations, can be avoided.

Abstract translation: 本发明提供了一种用于清洁污染的底物的方法和制剂，该方法包括用包含多种聚合物颗粒的制剂处理湿润的底物，其中所述制剂不含有机溶剂。 优选地，将基底润湿以达到1：0.1至1：5 w / w的基底与水的比例。 任选地，制剂另外包含至少一种清洁材料，并且在该实施方案中，优选地，聚合物颗粒用至少一种清洁材料涂覆。 优选地，清洁材料包括表面活性剂，其最优选具有洗涤剂性质。 最优选地，基底包括纺织纤维。 通常，聚合物颗粒包括尼龙颗粒，最优选以尼龙碎屑的形式。 所获得的结果与进行常规干洗方法时观察到的结果非常一致，并且该方法提供了显着的优点，即可以避免在成本和环境考虑方面具有所有伴随的缺点的溶剂的使用。
