Material
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. Water repellent is often used for the final goods below; Outdoor garments, Suit, Coat, Umbrella, Carpet, Surgical gown, Automotive engine filter, Cardboard, etc...
Water repellent mechanism
In order to improve the water repellency and durability, the key point is how the water repellent is regularly bonded to the fiber at the molecular level and stabilized on the fiber surface. For that, the following are important: ① To develop compounds (polymers) designed so that molecular chains are arranged in order. ② Establish a method for uniformly and stably attaching the developed compound to the fiber surface. NICCA offers water repellent agents that achieve ①②.
(1) Water repellent finish to fabric (2) Water repellency and breathability of water repellent fabric
By impregnating the fabric with a water repellent and heat treating it at high temperature, the water repellent nanoparticles bond to each single fiber. Since the entire fabric is not coated, the fabric remains breathable and repels raindrops such as rainwater.
