Abstract

Textile substrates are impregnated with a aqueous disperison of a fine crystalline wax containing carboxy and carboxylic acid ester groups, a paraffin wax and a non-ionic emulsifier, optionally together with an optical brightener and/or a resin finish, and then submitted to a heat treatment. The treated textile substrates have improved sewability.
