The technology uses the plastic material polyurethane, which when applied in the liquid state to the surface of the textile that is underlying in the professional raincoat, eventually hardens. The coating is created by adding micro-capsules that are glue-like substances of the healing agent to liquid polyurethane, and on hardening creates a resilient bond with the textile. Hence when there is a tear in the coating, the capsules burst in the area that is damaged. The sealant when it comes in contact with the air and water hardens, and the coating seals itself. The experiments in the laboratory have produced positive results, but there are a few obstacles that need to be cleared before the product is commercially available. The fact that the textile material can heal tears more than a certain millimeter and how water-resistant are the micro-capsules in producing the glue-like effect need to be worked upon. Nonetheless, a novel technology like this has a lot of potential in the future of smart textiles.
