Abstract
Abstract The present disclosure relates to a method for the continuous high-grade finishing of materials, for example textile materials such as cellulose fibers, synthetic fibers, and the like which can be dried and cured by the influence of heat. More particularly, the present disclosure relates to a method for the high-grade finishing of textile materials which comprises impregnating a textile with a desired chemical preparation and heat-treating said textile material by passing therethrough a gas which has been heated to a temperature of about 140*-190* C.
