Fabric treatment compositions and methods
View Patent ↗A liquid fabric treatment composition including a hydrocarbon wax, a crosslinking agent, and a polyester warp sizing agent. The liquid fabric treatment composition may include a disperse dye. Methods of using these compositions for dyeing cellulose-containing fabric with a disperse dye include contacting a fabric containing cellulose with a liquid fabric treatment composition to yield a pretreated fabric, and heating the pretreated fabric to yield a treated fabric. The treated fabric contains a urethane compound formed by a reaction of the hydrocarbon wax, the crosslinking agent, and the cellulose of the fabric.
