Fabric treatment for stain release

Abstract

A fabric treatment composition that includes at least one zeta potential modifier and a hydrophobic agent with a melting point or glass transition temperature below 100° C. that imparts fabric protection benefits, including improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better handfeel to treated fabrics. Particularly preferred compositions include at least one zeta potential modifier in an amount sufficient to adjust the zeta potential of the composition to be positive and greater than zero millivolts. Particularly preferred compositions also include a fluoropolymer. The composition can be used as a pretreatment prior to washing, through soaking or direct spray application, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, or used prior to or during the drying cycle of an automatic drying machine or refresher machine, or used prior to or in conjunction with an ironing device. The fabric treatment is complete when the fabric is cured by drying and/or heating.

Problems solved by technology

Usually, a thick or uneven coat results, which gives areas of incomplete oil and water repellency and a fabric hand feel that lacks softness.

These products can also decrease the porosity of fabric, resulting in uncomfortable conditions for the wearer during use.

An additional drawback of direct application products is that they cannot be used on fabrics that are already stained or soiled because they lock in stains and soils.

Additionally the coating should be cured at temperatures that are attainable in com
