CROSS-LINKING AND DYEING CELLULOSE FIBRES

摘要

A process for producing an evenly-dyed fabric comprising both cotton fibres and man-made cellulose fibres, in which a fabric is manufactured from both said fibres and is dyed, is characterised by impregnating the man-made cellulose fibres, prior to manufacture of the fabric, with a water-soluble, flexible linear polymer and a cross-linking agent reactive with cellulose, and, at a stage of the process prior to dyeing of the fabric, effecting a cross-linking reaction between the man-made cellulose fibres and the cross-linking agent, thereby producing a reduction in the dye affinity of the man-made cellulose fibres to a level more proximate to the dye affinity of the cotton fibres.
