541,030. Treating textiles with liquids etc.; coated fabrics. BLEACHERS ASSOCIATION, Ltd., KERSHAW, W., and WHITELEGG, C. J. June 25, 1940, No. 10837. [Class 15 (ii)] [Also in Group VIII] A linen-like finish is imparted to a cotton fabric by subjecting it, after bleaching, to a calendering or beetling treatment and then coating it with a solution in alkali of regenerated cellulose, a modified cellulose, or a cellulose ether, then partially drying it, treating it for the removal of alkali and washing and drying it. The fabric may be mercerized before or after bleaching. The calendering or beetling renders the fabric less permeable to the cellulose solution so that practically only the surface threads and hairs are coated and a lustrous, transparent film resistant to laundering is formed thereon. A lower alkyl cellulose ether or a glycol cellulose ether may be used. The solution is preferably of high viscosity, e.g. at least 50 c.g.s. units. Before the bleaching, the fabric may be dry cleaned with benzine, benzene, a chlorinated hydrocarbon, or other solvent for oils, fats, waxes, or resins. The process may be applied to the treatment of cotton drill, damask, or brocade fabrics. The cellulosic solution may be applied to both sides of the fabric. Specification 462,824 is referred to. |
