Abstract
Cellulosic artificial silk materials, e.g. fabrics formed from viscose rayon, acetate rayon or cuprammonium rayon, are chemically modified by impregnating them with a solution or dispersion of pyruvic aldehyde in the presence of an organic acid and thereafter heating the impregnated material, e.g. from 120 DEG to 100 DEG C. for 5 minutes. The impregnated material may be stretched to its original dimensions and may be maintained so stretched during the heating operation. In an example, a viscose rayon fabric is impregnated with a solution of 12.3 parts by weight of pyruvic aldehyde and 1.5 parts by weight of oxalic acid in 288 parts by weight of water, stretched to its original dimensions and dried. The fabric is then heated at 140 DEG C. for 5 minutes and bleached with aqueous sodium hypochlorite solution.ALSO:Cellulosic textile materials, e.g. fabric formed from cotton, viscose rayon, acetate rayon, or cuprammonium rayon in the form of mono-or multi-filament or staple fibre yarns, are dimensionally stabilized to laundering by impregnating them with a solution or dispersion of pyruvic aldehyde in the presence of an organic acid and thereafter heating the impregnated material, e.g. from about 120 DEG C. to about 160 DEG C. for about 5 minutes. The impregnated material may be stretched to its original dimensions and may be maintained so stretched during the heating operation. In an example a viscose rayon fabric is impregnated with a solution of 12.3 parts by weight of pyruvic aldehyde and 1.5 parts by weight of oxalic acid in 288 parts by weight of water, stretched on a tenter to its original dimensions and dried. The fabric is then removed from the tenter, heated at 140 DEG C. for 5 minutes and bleached with 0.5 Tw. aqueous sodium hypochlorite solution. The process is said to be especially applicable to regenerated cellulosic materials. The pyruvic aldehyde may be applied as a solution or dispersion in an organic liquid and the organic acid used may be acetic or tartaric.
