Description

Fluid-resistant treatment agent and garment treated therewith RELATED APPLICATIONS The present application is based on and claims priority from U.S. provisional patent application Ser. No. 63/535,755, filed on, no. 2023, 8, 31, which is incorporated herein by reference in its entirety. Background There are various different types of protective apparel that are intended to provide protection to the wearer. In certain embodiments, for example, protective apparel is designed to provide protection from liquids (e.g., water and/or oil). For example, such protective apparel is typically worn by first responders, medical personnel, public service providers, and military personnel. Notably, moisture and/or oil absorption and retention can adversely affect both the garment and the wearer. For example, if the garment retains moisture, the protective garment may become significantly heavier and/or affect the thermal characteristics of the garment, making the garment less effective at protecting its wearer from heat. Furthermore, for example, if the garment absorbs and/or retains oil, the protective garment may have reduced breathability, reduced chemical resistance, and/or may be subject to contamination. Therefore, water repellency and oil repellency are important considerations in apparel and fabric material treatments. In the past, treatments for providing water repellency and/or oil repellency have included fluorocarbon chemicals. Typically, fluorocarbon chemicals are durable and provide adequate water and oil repellency. Recently, however, various manufacturers, including textile manufacturers, have been placed under increased pressure to reduce the amount of fluorocarbon compounds incorporated into the product. For example, fluorocarbons are not readily biodegradable and may remain in landfills for many years in the future. Furthermore, fluorocarbon manufacturing and processing has been subject to greater scrutiny and government regulations. Thus, there is a need for water and oil resistant compositions or treatments that can be applied to protective apparel that are free or substantially free of fluorocarbon chemicals and that provide water and oil resistant properties. More particularly, there is a need for durable water and oil resistant compositions or treatments that are substantially or essentially free of fluorocarbon chemicals and that can be applied to all different types of garments and clothing layers (e.g., medical clothing, military clothing, tactical clothing, industrial work clothing, etc.). Disclosure of Invention In general, the present disclosure relates to protective apparel that may provide barrier protection against all different types of fluids, including water and oil. The present disclosure also relates to protective apparel that is substantially free of fluorocarbons. Furthermore, the present disclosure relates to a textile material for producing the protective garment described above. In one aspect, the present disclosure is directed to protective apparel comprising a textile material comprising a woven fabric, a knitted fabric, a nonwoven fabric, or a combination thereof, the textile material being treated with an anti-fluid treatment agent that impregnates the textile material, the anti-fluid treatment agent being substantially free of fluorochemicals, the anti-fluid treatment agent comprising a water resistant composition and an oil resistant composition, the oil resistant composition comprising a silicone-containing polymer. The water-resistant composition may be present in the anti-fluid treatment agent in an amount of about 0.05 wt.% to about 40 wt.%. In addition, the water-resistant composition may comprise an acrylic emulsion and/or may be substantially free of fluorocarbons. The anti-oil composition may be present in the anti-fluid treatment agent in an amount of about 0.05 wt.% to about 40 wt.%. In addition, the oil-repellent composition may comprise a cationically stable emulsion, may have a pH of about 2 to about 8, and/or may be substantially free of fluorocarbons. In one aspect, the anti-fluid treatment agent may comprise one or more wetting agents, wherein the one or more wetting agents comprise isopropyl alcohol. In addition, the anti-fluid treatment agent may comprise one or more cross-linking agents, wherein the one or more cross-linking agents comprise polyurethane. In one aspect, the water-resistant composition and the one or more wetting agents may be present in the anti-fluid treatment agent in a weight ratio of from about 4:1 to about 40:1. Further, in one aspect, the water-resistant composition and the one or more crosslinking agents may be present in the anti-fluid treatment agent in a weight ratio of from about 1:2 to about 15:1. In one aspect, the oil-repellent composition and the one or more wetting agents may be present in the anti-fluid treatment agent in a weight ratio of from about 5:1 to about 50:1. Further, the oil-repellent composition and the one or m
