This invention relates to benefit compositions, and processes for making and using such compositions.
Due to use and cleaning, articles that comprise fibers, for example, garments and linens can wrinkle. In order to reduce wrinkles, such garments and linens are typically ironed or steamed after cleaning. Unfortunately the effectiveness of such treatments is not durable as wrinkles reappear during cleaning, storage and/or in use/wear.
Accordingly, there is a need for a textile benefit compositions that consumers can use to impart durable anti-wrinkle properties to finished textile products.
A textile benefit composition comprising a polyurethane and/or a polyurethane co-polymer; a cross-linking agent; and a carrier.
The present invention also relates to processes for making and using the aforementioned compositions and textiles treated with such compositions.
Definitions

Examples of the Spray-Iron Product Compositions
Spray-Iron Application:
A fabric comprising 100% cotton fibers is placed on an ironing board and the composition of Example 1 is evenly sprayed on the fabric in a sufficient amount to achieve a wet pick up at about 50%. The fabric is then ironed until it is dry using a high temperature setting.

The garments, which include a shirt comprising 100% cotton fibers are placed in a container containing such mixture and agitated for about 5 minutes. The garments are then spun in a washer for 2 minutes and then ironed until it is dry.
Soak-Iron Application:
About 200 g of the composition of Example 2 is combined with 1000 g of water. The resulting mixture is stirred and/or agitated. The garments, which include a shirt comprising 50% cotton fibers and 50% polyester fibers are placed in a container containing such mixture and agitated for about 5 minutes. The garments are then spun in a washer for 2 minutes and then ironed until it is dry.
