Polyurethane is referred to as PU. Polyurethane elastomer is mainly used for Oxford cloth coating, and mainly solvent-based elasticity. Polyurethane elastomer is a kind of polyether diol or polyester diol containing active hydrogen, polymerized with diisocyanate and diamine or diol chain extender. It is composed of polyester or polyether flexible segment and isocyanate. The rigid segment composition is a block copolymer, which is highly elastic. It is a type of coating agent with excellent performance and wide application. Polyester polyurethane has good hydrolysis resistance and soft hand feel, but has poor light and heat resistance.
So can PU be added with a waterproof coating? The answer is that the main functions of waterproof Oxford fabric are: waterproof, moisture-permeable, breathable, insulating, windproof, and warm. In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics. At the same time, from a quality point of view, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have.
Waterproof Oxford cloth not only enhances the air-tightness and water-tightness of the fabric, but also has unique breathable properties, which can quickly discharge water vapor inside the structure, avoid mold breeding in the structure, and keep the human body always dry, which is a perfect solution It solves the problems of breathability, windproof, waterproof, warmth and other issues, and is a healthy and environmentally friendly fabric.
