High-performance organic silicon coated fabric and preparation method thereof Technical Field The invention belongs to the technical field of fabric function modification, and particularly relates to a high-performance organic silicon coated fabric and a preparation method thereof. Background The traditional fabric is deeply favored by consumers because of the flexibility of the textile design and the good air permeability and comfort, but is also a series of problems that the traditional fabric fibers are disturbed by external environments in the actual use process, such as dirt like coffee cakes, is turned over and embedded into the fibers, is difficult to clean and leaves dirt passively, or is more easily affected by moisture in a high-humidity environment and causes mildew on the surface. At present, the general improvement method for the antifouling and waterproof problems of the fabric surface mainly comprises the following steps: 1. By the post-finishing technology, on the premise of keeping the hand feeling of the fabric, the physical or chemical properties of the fiber surface are changed, and various polymers or additives, such as DWR (durable water-repellent) fluorine-containing polymer or other hydrophobic polymers, silver ion-containing or quaternary ammonium salt-containing antibacterial deodorizing additives and the like, are added on the surface of the fabric. However, these coatings are only functional in protection and their function is gradually diminished with washing and abrasion. 2.
