Water Repellent is a processing agent that covers the surface of fiber by nanoparticle compound and gives the fabric excellent water repellency. It also provides washing durability.
The advantage of this finishing is that it can keep the original hand of fabric itself without losing air permeability since it is not coating finish covering the fabric completely with thick resins
These products enable the modification of the textile’s surface in a manner that water, oil, coffee, wine, milk as well as other staining substances are repelled. The surface energy of is the textile is reduced to such an extent that oil, water and soil are no longer able to wet and penetrate the surface. High durability is ensured by integrating additional, reactive groups into the polymer as well as by using incorporated boosters. Depending on the degree of crosslinking and the orientation of the fluorocarbon polymer side chains, a differing hydrostatic head is formed.
