VERFAHREN ZUR KRUMPFFESTAUSRUESTUNG VON WOLLE

摘要

A method of shrink-proofing wool comprises providing an aqueous solution containing hypochlorite, permanganate and a wetting agent at a pH of from 6 to 7.7 by mixing together in a mixing vessel 3 supplies of aqueous liquid from at least two supply vessels 1, 2, the rate of supply of aqueous liquid from each of these supply vessels being automatically controlled in response to the liquid level in the mixing vessel, transferring the aqueous solution to a precision pad mangle 5, and continuously passing the wool through the pad mangle.
