Abstract
An improved method of treating fabrics made with natural fibers using hydroxymethylsulfonate to render the fabrics wrinkle resistant. According to the improved process, an alkylene glycol is incorporated in the sodium hydroxymethyl sulfonate padding bath used to impregnate the fabric thereby surprisingly reducing the amount of extractable formaldehyde from the dried fabrics.
