Abstract: The present invention provides a method of treating a nonwoven fabric to provide the fabric with repellency to fluids while minimizing impact to the hydrostatic head properties of the fabric. Generally, the process includes contacting a nonwoven fabric with an aqueous treatment solution that includes a fluoropolymer and a polymeric antistatic agent.

Abstract: Disclosed herein are fluorochemical blends suitable for producing repellency to low surface tension fluids such as, for example, alcohols, aldehydes, ketones and hydrophilic liquids, such as those containing surfactants. The fluorochemical blends may be beneficially utilized to produce low surface tension fluid repellency in extruded articles such as fibers and fibrous web materials, films and foams. Such repellent extruded articles are highly useful in a wide range of limited use and disposable products such as, for example, personal care products, mortuary and veterinary products, protective wear garments, and medical care garments and products. The fluorochemical blends include at least a first fluorochemical having a majority of first fluoroaliphatic groups having 4 or fewer carbon atoms, and a second fluorochemical having a majority of second fluoroaliphatic groups having 6 or more carbon atoms.

Abstract: Disclosed herein are extruded articles such as, for example, fibers and films, containing thermoplastic polymeric compositions having a copolymeric major component and a melt processable additive treatment, wherein the melt processable additives have enhanced segregation to or expression at the surface of the article, thereby improving the effect of the desired characteristic of the additive treatment. Also disclosed are multicomponent extruded thermoplastic articles having two or more distinct components arranged in a specific geometric arrangement, wherein the thermoplastic polymeric composition of at least one geometric component includes a copolymeric major component and a melt processable additive treatment. Also disclosed are web materials including the extruded articles.

Abstract: The present invention provides a method of treating a nonwoven fabric to improve alcohol repellency that includes contacting a nonwoven fabric with an aqueous treatment solution that includes a non-ionic fluoropolymer and essentially no antistatic agent or less than 0.05 weight percent by weight of an antistatic agent. The present invention also provides a nonwoven fabric with improved alcohol repellency.

Abstract: The present invention provides a method of treating a substrate to improve the alcohol repellency of the substrate while minimizing the effect on the hydrostatic head value of the substrate that includes contacting a substrate with a treatment solution that includes an ionic fluoropolymer, a monovalent salt, and essentially no antistatic agent or less than 0.05 weight percent by weight of an antistatic agent.
