Abstract

A fabric having a unique combination of stain resistance, fluid barrier properties, aesthetic characteristics and drape ability is described, and a method of making such fabrics. The fabric includes a fabric substrate that has been treated with a low surface energy stain resist compound on at least one of its surfaces, and one or more layers secured to the other of its surfaces, with the layers providing the fabric with the unique combination of characteristics. In addition, the fabric is desirably provided with flame resisting and ultraviolet resisting characteristics, to enable it to be used as a seating material for transportation vehicles. Methods for making the fabric are also described.
