The present invention relates to a method for manufacturing an aerogel sheet and comprises: a step (a) of impregnating an acid solution into a fiber sheet to clean the fiber sheet by using the acid solution and impregnating a binder solution into the fiber sheet that is cleaned by using the acid solution to manufacture a pre-processed fiber sheet; a step (b) of impregnating a silica precursor into the pre-processed fiber sheet; and a step (c) of a gelling catalyst into the fiber sheet into which the silica precursor is impregnated to gelate the silica precursor.

A screw conveyor based fabric dyeing machine including a machine body inside which a screw conveyor including a conveying screw and a fabric support board is arranged and generally parallel to an extension direction of the machine body. Fabric moves through a dyeing tube arranged with the machine body to fall down onto the screw conveyor so that the fabric can be conveyed by the screw conveyor forward through the machine body to reach a guide roller and a nozzle to complete a cycle of circulation for subsequently re-entering the dyeing tube to be dyed therein. As such, water consumption can be reduced and dyeing performance is enhanced, achieving energy saving and carbon reduction, reducing contamination to the surroundings, and realizing green economy.

Supercritical fluid (SCF) is used to scour a target material to leave scour elements, such as oligomers and oils from the target material. Carbon dioxide (CO.sub.2) is introduced into a pressure vessel also containing the target material to be scoured. The CO.sub.2 is raised in temperature and pressure to a SCF state. The CO.sub.2 is recirculated within the pressure vessel to scour the target material. An exchange of the CO.sub.2 is occurs allowing for the scoured elements to be removed from the CO.sub.2 and therefore from within the pressure vessel. Operation variables such as temperature, pressure, time, internal flow rate, and CO.sub.2 exchange are adjusted to achieve a scouring of the target material.

Methods are directed to the use of a supercritical fluid for finishing a target material with a finishing material. One or more variables selected from temperature, pressure, flow rate, and time are manipulated to increase efficiencies in the finishing process. As temperature or pressure are decreased causing a change in the density of a supercritical fluid carbon dioxide, which in turn causes a precipitation of dissolved material finish with the carbon dioxide, other variables are maintained above threshold values to increase the uptake of the material finish by the target material. This improvement reduces time by limiting cleaning processes of the system, saves materials used in the cleaning process, and saves energy used to achieve cycles of the process, in aspects.

A liquid fabric treatment composition including a hydrocarbon wax, a crosslinking agent, and a polyester warp sizing agent. The liquid fabric treatment composition may include a disperse dye. Methods of using these compositions for dyeing cellulose-containing fabric with a disperse dye include contacting a fabric containing cellulose with a liquid fabric treatment composition to yield a pretreated fabric, and heating the pretreated fabric to yield a treated fabric. The treated fabric contains a urethane compound formed by a reaction of the hydrocarbon wax, the crosslinking agent, and the cellulose of the fabric.
