A wrinkle-free / wrinkle-resistant cellulosic fiber-containing fabric which retains tensile-, tear- and abrasion-strength due to the reduction of hydrogen bonding in the fabric is obtained by a process which comprises pretreating the fabric with the processes to reduce and control hydrogen bonding in the fabric, and treating a cellulosic fiber-containing fabric with aqueous formaldehyde and a catalyst in liquid form capable of catalyzing the cross-linking reaction between the formaldehyde and cellulose. Such cross-linking is carried out by heat-curing the cellulosic fiber-containing fabric under saturated steam with or without high pressure and / or infrared or far-infrared radiation and / or high frequency (induction) radio waves. Under such conditions the formaldehyde reacts with cellulose in the presence of catalyst with no substantial loss of formaldehyde prior to said reaction so as to improve the wrinkle-free or wrinkle-resistant property of the fabric without substantial strength loss. This is accomplished by maintaining the moisture level during curing high enough to prevent detrimental increase in hydrogen bonding above the reduced level of hydrogen bonding by the prior process of liquid ammonia treatment and / or aqueous wetting. Such precise control of moisture and formaldehyde at curing is also achieved by superheated steam cure, moist-cure, which controls the same level of moisture throughout the curing process, or mild-cure with steam lower than 212 DEG F. (100 DEG C.).
