ABSTRACT:
A process is disclosed for imparting wrinkle-resistance and durable press properties to a fibrous garment which is, desirably, made at least in part of a cellulose fiber. The process involves wetting the fiber or garment such that natural fibers swell or the garment has at least about 30 percent by weight of water. The wetted garment, having the swollen fibers, is then treated with a resin solution. The resin must be suitable for imparting wrinkle-resistance and durable press properties to the fibrous garment. Such resins are known in the art. The resin "treating" solution desirably comprises at least about 10 percent excess of a stoichiometric amount of the resin. The excess solution is removed and the fabric or garment is then dried. The invention can include a step for recycling the excess solution from the treating procedure.
