Abstract
A method of molding cloth. A special multi-layer cloth is drawn into a mold by means of a vacuum between the cloth and the mold. The cloth includes a fabric layer, stitches of the fabric having never been thermally set, a polyurethane foam layer and a polyvinyl chloride film layer bonded together. After the cloth has conformed to the contours of the mold, the shape of the cloth is fixed to maintain the mold contours. To this end, the cloth may be heated, or polyurethane foam may be poured into the mold and allowed to expand.
Claims21
A process for molding cloth comprising the steps of:
- drawing the cloth into a mold, the cloth including a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, and an elastic composition layer bonded to the fabric layer;
- and
- fixing the shape of the cloth to maintain the mold contours.
A process for molding cloth comprising the steps of:
- drawing the cloth into a mold, the cloth including a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, and an elastic composition layer bonded to the fabric layer, the elastic composition layer including a film layer;
- and
- fixing the shape of the cloth to maintain the mold contours.
A process for molding cloth comprising the steps of:
- drawing the cloth into a mold, the cloth including a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, and an elastic composition layer bonded to the fabric layer, the elastic composition including a flexible foam layer and a film layer;
- and
- fixing the shape of the cloth to maintain the mold contours including heating the cloth.
A process for molding cloth comprising the steps of:
- drawing the cloth into a mold, the cloth including a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, and an elastic composition layer bonded to the fabric layer;
- and
- fixing the shape of the cloth to maintain the mold contours, including heating and cooling the cloth.
A process for molding cloth comprising the steps of:
- preheating the cloth, the cloth including a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, and an elastic composition layer bonded to the fabric layer, the elastic composition layer including a film layer,
- drawing the cloth into the a mold;
- and
- fixing the shape of the cloth to maintain the mold contours, including heating and cooling the cloth.
A process for forming a cloth-covered item comprising the steps of:
- drawing the cloth in a mold, the cloth including a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, and an elastic composition layer bonded to the fabric layer;
- and
- fixing the shape of the cloth to maintain the mold contours, including pouring foam into the mold.
A process for molding cloth comprising the steps of:
- bonding a flexible foam layer to a film layer, the foam layer and film layer forming an elastic composition layer;
- bonding the foam layer to a fabric layer having a heat-fixable fiber, stitches of the fabric having never been thermally set, the cloth comprising the foam layer, film layer and fabric layer;
- drawing the cloth into a mold;
- and
- fixing the shape of the cloth to maintain the mold contours.
A process for forming a cloth-covered item comprising the steps of:
- bonding a flexible foam layer to a film layer, the foam layer and film layer forming an elastic composition layer;
- bonding the foam layer to a fabric layer having a heat-fixable fiber, the stitches of the fabric having never been thermally set, the cloth comprising the foam layer, the film layer and the fabric layer;
- preheating the cloth;
- drawing the cloth into a mold;
- and
- fixing the shape of the cloth to maintain the mold contours, including heating the cloth, cooling the cloth, and pouring foam into the mold.
