A process for scavenging free formaldehyde from cellulosic-containing articles, such as textile materials, which process comprises contacting the cellulosic-containing textile material containing free formaldehyde with a formaldehyde scavenger which comprises a heterocyclic compound free of carbonyl groups, and containing an NH group, with the ring made up of nitrogen or carbon atoms, the ring being unsaturated or, when fused to a phenyl group, being unsaturated or saturated, and the NH group bonded to a carbon or nitrogen atom which is directly bonded by a double bond to a carbon or nitrogen atom.
