Self-cleaning and washable cotton and cotton blends

Background

Cotton is the most widely used fabric mostly because of its good properties: pleasant to touch, breathability, hydrophilic character, aesthetic looks, natural resource. We are able to add some characteristics to cotton: superhydrophobic and oleophobic effect, while preserving breathability. Our cotton becomes a product with superpowers – we are introducing waterproof cotton, resistant to oil stains.

Description of invention

The invention relates to the preparation of breathable superhydrophobic and oleophobic coating for cotton and cotton-polyester textiles that has inclined angle lower than 10̊ even after ten washings. This is achieved with the preparation of micro and nano roughness and adding extra hidrofobic and oleofobic organic silan precursors.

Main advantages

Natural fabric with additional properties: repels water and oil droplets
Washable – retains its properties even after many washes.
