Description

This invention relates to a method for producing fabric materials, such as apparel fabric materials, having a base fabric material injected or impregnated with one or more beneficial agents. This specification discloses the use of a supercritical fluid (SCF) method for injecting or impregnating fabric materials, such as apparel fabric materials, with one or more beneficial agents (e.g., antimicrobial agents, flexibility-enhancing additives, elasticity-enhancing additives, fabric-strengthening additives, UV-protective additives, etc.). In some embodiments, the present invention discloses a fabric composition, such as an apparel fabric composition, comprising: a base fabric material having a surface portion and an inner portion; and a beneficial agent incorporated throughout the base fabric material, wherein at least a portion of the inner portion of the base fabric material is impregnated with the beneficial agent. In some embodiments, the base fabric material is a fabric material, a mesh material, a foam material, a gel material, or a combination thereof, or a laminate. In some embodiments, the base fabric material is a natural or naturally derived material. In some embodiments, the natural or naturally derived material is selected from cotton, linen, hemp, bamboo, silk, jute, ramie, coir, rayon, cellulose, recycled materials thereof, and formulations thereof. In some embodiments, the base fabric material comprises a synthetic material, which may be selected from polyester, nylon, acrylic, spandex, polyolefin, neoprene, fleece, microfiber, synthetic leather/suede, recycled materials thereof, and formulations thereof, as needed. In some embodiments, the beneficial agent comprises an antibacterial agent. In some embodiments, the beneficial agent comprises a deodorant, a performance additive, or a combination thereof. In some embodiments, the anti-infective agent is a quaternary ammonium salt. In some embodiments, the quaternary ammonium salt comprises a C12 or C14 alkyl chain. In some embodiments, the quaternary ammonium salt is neither benzalkonium chloride nor a polymeric quaternary ammonium salt. In some embodiments, the quaternary ammonium salt is C12-C14-alkyl(ethylbenzyl)dimethylammonium chloride. In some embodiments, the quaternary ammonium salt is C12-alkyl(ethylbenzyl)dimethylammonium chloride. In some embodiments, the quaternary ammonium salt is C14-alkyl(ethylbenzyl)dimethylammonium chloride. In some embodiments, the immunosuppressant is a calcineurin inhibitor. In some embodiments, the immunosuppressant is selected from the group consisting of cyclosporine, tacrolimus, and pimecrolimus. In some embodiments, the immunosuppressant is tacrolimus. In some embodiments, the beneficial agent is unevenly impregnated throughout the apparel fabric material. In some embodiments, the beneficial agent is uniformly impregnated throughout the apparel fabric material. In some embodiments, at least 30% of the inner portion of the base fabric material is impregnated with the beneficial agent. In some embodiments, at least 50% of the inner portion of the base fabric material is impregnated with the beneficial agent. In some embodiments, at least 60% of the inner portion of the base fabric material is impregnated with the beneficial agent. In some embodiments, at least 70% of the inner portion of the base fabric material is impregnated with the beneficial agent. In some embodiments, the composition is prepared by a method comprising bringing the base fabric material and the beneficial agent into contact with supercritical fluid carbon dioxide (SCF- CO2 ) in an enclosure under high pressure, thereby enabling the beneficial agent to impregnate at least a portion of the inner portion of the base fabric material. In some embodiments, the method further comprises depressurizing the enclosure after impregnating at least a portion of the inner portion of the base fabric material with the beneficial agent. In some embodiments, the base fabric material and beneficial agent are introduced into the enclosure, and then SCF- CO2 is introduced into the enclosure.
