Abstract: As cotton bales are produced by obtaining lint cotton by subjecting collected seed cotton to a ginning process, linear polyorganosiloxane of a specified type which has 10-6000 siloxane units and is insoluble or dispersive in water is adhesively attached to the seed cotton or to the lint cotton by 0.03-2.0 weight % with respect to the lint cotton.

Abstract: A multilayer coating is produced on a substrate by a process in which an aqueous dispersion containing(A) a carbonyl-containing copolymer of monoolefinically unsaturated compounds, not less than 10% by weight of which have carbonyl groups which react with hydrazide groups, and(B) polyhydrazides,is applied as a base coat to the substrate, the water is flashed off and one or more further conventional coats are applied to this base coat as a dispersion or solution, the solvent is flashed off and, if required, the resulting multilayer coating is baked for from 10 to 60 minutes at from 70.degree. to 180.degree.
