Latest Patents

Quertain's latest patents include a unique cloth molding process. This method involves a special multi-layer cloth that is preheated and drawn into a heated mold using a vacuum. The cloth consists of a fabric layer with heat-fixable fibers, a polyurethane foam layer, and a polyvinyl chloride film layer. The cloth is preheated to the higher temperature of either the fabric layer or the polyvinyl chloride film, while the mold is heated to the same temperature. Once the cloth conforms to the mold's contours, it is transferred to a cooler mold, which sets the fabric's stitch to the mold's shape. This process allows for the pouring of polyurethane foam into the mold, enabling it to expand and form a seat cushion or similar product.
