WATER REPELLENT FINISH
ABSTRACT Fluorocarbon (FC) gives fiber surfaces the smallest amount surface energies of the repellents finishes in use. Even though perfluorocarbon are successful in providing water repellent properties, its products are in the negative list of environmental associations because to their toxic properties. Finishing procedures that are formed on nanostructured surface roughness will be of extreme importance to give both fluorine-free repellent finishes and also durability in the mean of self-healing properties.
W
ater Repellent is finish that is used on the fabric by adding is a Repellent processing agent that covers the surface of fiber by nanoparticle compound and provides the fabric good water repellency. This process also gives washing durability.
• Mechanism of the process:-
The benefit of this finishing is that it can contain the authentic hand of fabric itself by not losing air permeability as it is not coating finish covering the fabric fully along with thick resins. • These are the final goods of Water repellent Finish:

To increass the water repellency and durability, the important point is the way water repellent is regularly bonded to the fiber at the molecular level and stabilized on the fiber surface.
