    • 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.
    • 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。

    • A densified fluid barrier cleaning system is disclosed in which a pressure vessel encases a movable basket positioned so as to cross a barrier such that one opening of the pressure vessel resides in a first environment and a second opening of the pressure vessel resides in a second environment. A tubular basket within the pressure vessel is positioned such that its central longitudinal axis is aligned with both the first and second opening of the pressure vessel. Responsive to the successful completion of a cleaning cycle, soiled articles that are introduced to the basket via the first opening from the first environment can be removed through the second opening and into the second environment thus bridging the barrier without fear of introducing contaminants from the first environment to second environment.
    • 公开了一种致密化的流体屏障清洁系统,其中压力容器包围可移动的篮,其定位成跨越障碍物,使得压力容器的一个开口位于第一环境中,并且压力容器的第二开口位于第二环境 。 压力容器内的管状篮被定位成使得其中心纵向轴线与压力容器的第一和第二开口对准。 响应于清洁循环的成功完成,通过第一开口从第一环境引入到篮子中的污染物品可以通过第二开口被移除并进入第二环境,从而桥接隔离物,而不用担心从第一开口引入污染物 环境到第二环境。
