Abstract
The treatment of textiles by a fluoropolymer-branched silicone polyether composition is disclosed. The fluoropolymer-branched silicone polyether compositions are prepared by combining a fluoropolymer and a branched silicone polyether. The resulting compositions improve the hand or feel of the fabric without significantly diminishing oil repellency nor the stain release properties associated with fluoropolymers. The branched silicone polyethers can be used alone to improve the feel of fabrics, without diminishing the hydrophilicity of the fabric.
