Composite fabrics are a new type of material made by bonding one or more layers of textile, non-woven, and other functional materials together. The purpose of bonding is to combine two or more layers of materials to achieve specific functions, such as increasing thickness to improve warmth (composite fleece lining), or achieving functions like rainproofing, breathability, and windproofing through multi-layer bonding (such as three-layer bonding). The bonding process mainly uses adhesives; currently, commonly used adhesives in the clothing industry include polyurethane hot melt adhesives (TPU/PUR hot melt adhesives) and oil-based adhesives. Internationally popular bonding processes mainly include hot melt adhesive powder dot coating, hot melt adhesive paste dot coating, hot melt adhesive powder sprinkling, hot melt adhesive double-dot coating, polyurethane spray coating, and polyurethane roller coating.
Composite fabrics are made by using microfibers in specific textile processing and unique dyeing and finishing, and then processing them through "composite" equipment. Their English names are "Lamination Fabric" and "Soft Shell Fabric." Due to the use of microfibers, this fabric has a high cleaning ability, i.e., stain removal ability.
