CLOTH MOLDING PROCESS |
摘要 |
A method of molding cloth. A special multi-layer cloth is first preheated and then drawn into a heated mold by means of a vacuum between the cloth and the mold. The cloth includes a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, a polyurethane foam layer and a polyvinyl chloride film layer bonded together. The cloth is preheated to at least the greater of the set temperature of the fabric layer and the softening temperature of the polyvinyl chloride film. The mold is heated to at least the same temperature. After the cloth has conformed to the contours of the mold, the cloth is either cooled in the mold or transferred to a cooler mold. The steps of heating the cloth in the mold and then cooling the cloth sets the stitch of the fabric to the contours of the mold. Polyurethane foam may then be poured into the mold and allowed to expand to form a seat cushion or the like. |
