Many textiles are water-repellent. We are familiar with water-repellent textiles for outdoor clothing, bags and tents, for example.
But what does unwettable mean?
What is the difference between unwettable and water-repellent?
Water-repellent:
Water-repellent means that a material or fabric does not absorb water immediately, but allows it to roll off. The water remains on the surface in the form of droplets and does not penetrate or only penetrates very slowly. It is therefore not waterproof, but offers a certain degree of protection against moisture.
Unwettable:
Unwettable means that the textile not only repels water but cannot absorb any water at all. There is no adhesion of water to the textile.
