Disclosed is a method for providing a textile material(s) resistant to the deposition of oil- and grease-based air pollutants by treating the textile material(s) with an oil/grease resistant composition. The oil/grease resistant composition comprises a modified polysaccharide(s), particularly, polysaccharides modified with anionic groups, and one or more adjuvant materials.

Processes for converting textiles from water and oil absorbent textiles to water and oil repellent textiles and for treating textiles to increase fluid repellant properties of the textiles. The treated textiles may be used, for example, as PPE for healthcare workers that are faced with a shortage of PPE materials. The processes add a fluid repellant, such as a fluoropolymer-based fluid repellant, during a stage of a laundry process, for example at the sour stage. The fluid repellant may be added multiple times during a laundry process.
