Abstract:
1. A method for treating a fabric, including de-sized fabrics and previously bleached hydrophilic fabrics, wherein the fabric includes threads oriented in a first fabric direction and threads oriented in a second fabric direction crossing the first fabric direction, wherein the threads oriented in the first fabric direction are made of natural or artificial cellulose fibers, and wherein the method comprises the steps of: applying a metal peroxide to the fabric so that the fabric is impregnated with the metal peroxide, while leaving the fabric free and without tension in the first fabric direction and while placing the fabric under tension in the second fabric direction, for a period of time necessary for swelling of the fibers oriented in the first fabric direction and for modification of the fibers; passing the impregnated fabric in air, while leaving the fabric relaxed and without tension in the first fabric direction and while placing the fabric under tension in the second fabric direction, swelling the threads oriented in the first fabric direction and causing the threads to assume a spring shape, after shrinkage, at least one rinsing of the fabric; at least one washing of the fabric; and at least one squeezing of the fabric.
