摘要： The present invention relates generally to cleaning systems, and more specifically to substrate cleaning systems, such as textile cleaning systems, utilizing an organic cleaning solvent and a pressurized fluid solvent. However, unlike conventional cleaning systems, a conventional drying cycle is not necessary. Particularly, the present invention provides a process for cleaning substrates by cleaning the substrates with an organic solvent in absence of liquid carbon dioxide, and removing the organic solvent from the substrates using a pressurized fluid solvent.

摘要： Method includes the steps of (1) treating the textile with a predetermined amount of a non-durable sacrificial repellent material before putting the textile in service; (2) cleaning the textile with a mixture of a non-polar solvent and at least one cleaning additive to remove non-polar solvent soluble, insoluble and resistant contaminants from the textile; (3) washing the textile with a mixture of a polar solvent and at least one washing additive to remove polar solvent soluble contaminants from the textile; and (4) maintaining a predetermined amount of a non-durable sacrificial repellent material on the textile. The non-polar solvent may be perchloroethylene or the like, while the cleaning additive is a mixture of a dialkyl ketone, a carboxylic ester and a glycol ether. A second cleaning additive may be used to enhance contaminant removal. The polar solvent used is water, while the washing additive is a blend of surfactants. The repellent material used is either a fluorocarbon polymeric material or a hydrocarbon polymeric material, which is applied as necessary to maintain a predetermined amount of the non-durable sacrificial repellent material on the textile in the range of from about 0.5 to about 3.0% solids on fabric by weight. Drying steps are preferred after the non-polar solvent cleaning step so as to remove any residual non-polar solvents, and after the maintaining step so as to cure the non-durable sacrificial repellent material thereon.
摘要翻译：方法包括以下步骤：（1）在使织物投入使用之前用预定量的非耐用牺牲驱避剂材料处理织物; （2）用非极性溶剂和至少一种清洁添加剂的混合物清洗纺织品，以从纺织品中除去非极性溶剂可溶性，不溶性和耐受性的污染物; （3）用极性溶剂和至少一种洗涤添加剂的混合物洗涤织物以从织物中除去极性溶剂可溶性污染物; 和（4）在纺织品上保持预定量的不耐用的牺牲驱避剂材料。非极性溶剂可以是全氯乙烯等，而清洁添加剂是二烷基酮，羧酸酯和二醇醚的混合物。可以使用第二清洁添加剂来增强污染物去除。所使用的极性溶剂是水，而洗涤添加剂是表面活性剂的混合物。使用的驱虫剂材料是氟碳聚合物材料或烃聚合物材料，其根据需要施加以将织物上预定量的非耐用牺牲驱避剂材料保持在约0.5至约3.0％固体的范围上织物重量。在非极性溶剂清洗步骤之后，干燥步骤是优选的，以除去任何残留的非极性溶剂，并且在维持步骤之后，使其上的非持久性牺牲驱避剂材料固化。

摘要： A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum. Finally, the drum is de-pressurized to atmospheric pressure to evaporate any remaining pressurized fluid solvent, yielding clean, solvent free textiles. The organic solvent is preferably selected from terpenes, halohydrocarbons, certain glycol ethers, polyols, ethers, esters of glycol ethers, esters of fatty acids and other long chain carboxylic acids, fatty alcohols and other long-chain alcohols, short-chain alcohols, polar aprotic solvents, siloxanes, hydrofluoroethers, dibasic esters, and aliphatic hydrocarbons solvents or similar solvents or mixtures of such solvents and the pressurized fluid solvent is preferably densified carbon dioxide.
