Abstract:
The present invention relates to a method of extracting oil of cloth via supercritical fluid, comprises the steps of: a cloth to be extracted is provided in an extracting tank; a gas is filled into a storing tank; a water-cooling machine is provided and served to cool down the temperature of the gas; a pump is provided and served to compress the gas; a water-heating machine is provided and served to raise the temperature of the gas so the gas becomes a supercritical fluid; and the supercritical fluid is inserted into the extracting tank for extracting the oil. By the above mentioned method, the cleanness of the cleanroom wiping cloth can be immediately sensed and obtained, and the gas can be recycled for achieving energy-saving.
Abstract:
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 dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether or tripropylene glycol methyl ether, a mixture thereof, or a similar solvent and the pressurized fluid solvent is preferably densified carbon dioxide.
Abstract:
A cleaning composition that can discharge the color of blood, menstrual fluids, or other organic stains is provided. In particular, the present invention achieves a balance between control of unwanted liquid spreading by lateral wicking on a stained textile fabric to lessen the size of wet spots and maintaining the cleaning efficacy of the composition by means of specific kinds of thickening agents. The composition includes an oxidizing agent such as peroxides, a cell-lysing agent, a chelating agent, an antioxidant, a thickener, and other optional ingredients that are selectively employed to achieve an aqueous based composition that exhibits good shelf stability and stain removal properties. The thickening agent may include a cellulosic or clay material, starch, gum, fatty acid, fatty alcohol, hydrophilic colloidal particles, polyoxyethylene glycol or polyoxyethylene glycol derivatives including fatty acid esters and ethers, or a combination thereof.

The present invention relates to a succinic diester polymer which is used in the preparation of water-in-oil macroemulsions. Said polymer, which has an excellent ability to stabilize a water-in-oil macroemulsion, has the formula (I) wherein L is a polyalkenyl group having a number average molecular weight of from 600 to 1,500, A1 and A2 independently are poly(alkyleneoxy) chains with a molecular weight of from 500 to 1,200, where each alkyleneoxy group contains 2 or 3 carbon atoms and the number of alkyleneoxy groups being ethyleneoxy groups is at least 50% of the total number of alkyleneoxy groups, and R1 and R2 independently are alkyl groups having of from 1 to 3 carbons atoms. The succinic diester polymer may also be combined with one or more surfactants having a hydrocarbon group or acyl group of 8-22 carbon atoms, which surfactants are selected from the group consisting of alkoxylated alcohols, alkoxylated amines, amine oxides containing alkyleneoxy groups, alkoxylated esters, alkoxylated acids, alkoxylated amides, sugar surfactants, and compounds of the formula: R3O—C(O)—R4—C(O)—N(R1)—(CH2)n—NH—C(O)—R2 (II) wherein R1 and R2 are independently selected from C8-C22 alkyl/alkenyl groups, R3 is a hydrogen or a C1-C5 alkyl group, R4 is a C1-C5 alkylene or alkenylene group, and n is an integer of from 2-5, with the weight ratio between succinic diester polymer and surfactant being 1:9 to 9:1. The emulsions of the invention can be used as a diesel fuel, a gasoline fuel, a heating fuel, a dry cleaning liquid, a metalworking fluid or a personal care formulation.
