UV curable textile finishes: Superhydrophobic and oleophobic, side-specific, dual finish treatment of cotton for apparel, home, technical and sport textiles

The advantages of UV curable textile finishes over thermal curing formulations are clear and include lower energy consumptions, increased processing speeds and smaller plant space. However, example current drawbacks include issues related to the loss of substrate flexibility, breathability and hand.
The achievement of side-specific, water and oil repellent functionality in textiles is highly desirable in articles such as sports clothing. In this case it is expected that the inside of the article absorbs sweat and that the outside surface repels rain and stains. Other examples can be found in the apparel, home and technical textiles.
In our work, we have developed a UV curable formulation, and respective application process, that allows one to obtain superhydrophobic and oleophobic cotton articles, maintaining the other intrinsic properties of cotton fabrics. Furthermore, the treatment may be side-specific and is resistant to common washing processes.
