Beschreibung
Zusammenfassung:	The present invention provides polymers and prepolymers which can be used in a method for the shrinkproofing of wool. This method not only confers a good level of shrink resistance, but also gives improved dyeing properties and a soft handle even without the use of additional softening agents. The polymers and prepolymers of essentially result from the reaction of one or more polyoxyalkyleneamines, either as a simple mixture or joined by a polyfunctional bridging group in a prior reaction, with an epihalohydrin or other reactive species, such as formaldehyde, so as to generate a grouping on the molecule capable of reacting with protein fibre surfaces. The reactants are used in such proportions that preferably, though not necessarily, all of the amino groups are reacted.
