Abstract: Methods for improving the brightness and durable press properties of fabric comprise treating the fabric with an aqueous solution comprising formaldehyde, catalyst for crosslinking the formaldehyde with natural fibers in the fabric, and silicone elastomer or precursor thereof, and heating the treated fabric to react the formaldehyde with natural fibers in the fabric. Methods for improving the brightness and shrinkage resistance properties of fabric comprise treating the fabric with an aqueous solution comprising formaldehyde, catalyst for crosslinking the formaldehyde with natural fibers in the fabric, and silicone elastomer or precursor thereof, and heating the treated fabric to react the formaldehyde with natural fibers in the fabric. Cellulose fabric which has a crosslinked formaldehyde durable press treatment and has been subjected to laundering with a brightener-containing detergent exhibits enhanced brightness after the laundering.

Abstract: Methods for providing fabric with improved fibrillation resistance and/or improved pill resistance comprise treating the fabric or fibers thereof with a treatment composition comprising formaldehyde, catalyst for cross-linking the formaldehyde with natural fibers in the fabric, and silicone elastomer or a precursor thereof, and heating the treated fabric to effect cross-linking of the formaldehyde. Fabrics having improved fibrillation resistance and/or improved pill resistance, and in specific embodiments, in combination with additional advantageous properties, are produced.

Abstract: Methods for reducing the trying time of fabric comprise treating the fabric with a treatment composition comprising formaldehyde, catalyst for crosslinking the formaldehyde with natural fibers in the fabric, and silicone elastomer or a precursor thereof, and heating the treated fabric to effect crosslinking of the formaldehyde. Fabrics having reduced drying times, particularly in combination with additional advantageous properties, are produced.
