Delay cure finishes

Two factors emerged to turn the focus of durable press the discovery that incorporation of a level of nylon or polyester in the fabric can substantially increase the garments abrasion resistance, and the reali2ation that the marketplace preferred cotton—polyester blends in delayed cure operations, even though 85% cotton—15% nylon fabric yields a suitable product. The 50% cotton—50% polyester fabric seemed particularly appropriate because it contained sufficient ceUulosic to benefit from a chemical finish and sufficient synthetic to provide strength and abrasion resistance. 

In the presence of a suitable catalyst, FIXAPRET PH is suitable for the delayed curing, as used in the BASF P2 process for permanent-press finishing. FIXAPRET PH can also be used for moist cross-linking.
