Methods are described for treatment of aramid fibers to modify the surface of the fibers. The treated fibers have improved adhesion to elastomer materials as compared to untreated fibers. Modification methods include irradiating the fibers, compressing and straining the fibers under a constant pull force and immersing the fibers in a coupling agent fluid. The treated fibers can be used with elastomers and provide reinforcement elements in products such as tires.

An object of the present invention to realize a step of producing an environmentally friendly textile product using a solvent in place of conventionally used water or an organic solvent in a textile product scouring step. A method according to one aspect of the present invention includes a step (a) of bringing a fluid containing supercritical carbon dioxide into contact with the textile product to remove part or all substances adhered to a surface of the textile product.

The present invention relates to a low-dust, high insulation aerogel blanket and a method for producing the same. More specifically, the present invention provides a method for producing a low-dust, high insulation aerogel blanket, wherein a plate type Mg(OH).sub.2.MgO.SiO.sub.2 powder is added to a silica sol, thereby being capable of reducing the generation of dust with excellent flame retardancy and thermal conductivity, and an aerogel blanket produced thereby.

A method for manufacturing a foamed fabric includes providing a fabric which includes at least one layer including a plurality of first foamable filaments made from a first foamable polymeric material, infusing the fabric with a supercritical fluid in a pressurized vessel, subjecting the infused fabric to a depressurizing process to permit the at least one layer to undergo an initial stage of foaming so as to obtain a pre-foamed fabric, placing the pre-foamed fabric in a mold cavity, and heating the mold cavity to obtain a molded foamed fabric.

A method for processing textile fibers is provided. The method comprises: adding a plurality of raw materials for processing textile fibers into a plurality of kettles; preparing supercritical carbon dioxide; obtaining one or more natural plant dyes and one or more natural plant extracts from the plurality of raw materials, and dissolving the one or more natural plant dyes and the one or more natural plant extracts in the supercritical carbon dioxide; dyeing and functionally modifying the textile fibers simultaneously by using the supercritical carbon dioxide carrying a mixture of the one or more natural plant dyes and the one or more natural plant extracts; performing a post-process to recycle the supercritical carbon dioxide; and performing a cleaning process to clean the one or more natural plant dyes and one or more natural plant extracts.

Methods are directed to the use of a supercritical fluid for performing a dyeing of a material such that dye from a first material is used to dye a second material. A supercritical fluid is passed through a first material in a pressurized vessel. The supercritical fluid transports the dye from the first material to at least a second material causing a dye profile of the second material to change as a result of dye from the first material perfusing the second material.

A device for color-fixing processing on textiles includes a supercritical carbon dioxide fluid unit, a fixing liquid storage tank (2) and a fixing reactor (9). The fixing liquid storage tank (2) is below the fixing reactor (9) and sealed connected by a connecting device (6). The fixing liquid storage tank (2) has a cylindrical cavity in which a fluid distributor (4) is mounted. The fluid distributor (4) is composed of several interconnected pipes which bend down with the nozzles downward, and one of the pipes is used as circulated fluid inlet (1) connected with the supercritical carbon dioxide fluid unit, and the rest of the pipes are used as circulated fluid outlets.
