Abstract
A method of coating a three-dimensional fabric has the steps of: preparing a three-dimensional fabric having two fabric layers and a plurality of vertical yarns connected between the two fabric layers; guiding the three-dimensional fabric with the two fabric layers vertically in the horizontal plane to an coating space, when the three-dimensional fabric moves in the coating space, a tension on the surface of the two fabric layers is between 5 and 25 kilograms (kg); applying an adhesive to the surface of the two fabric layers, and the adhesive spreading vertically and fluidly; and providing a reaction condition such that the adhesive dries into a film and forms a bonding layer.

A method of coating to a three-dimensional fabric, comprising the steps of:
- preparing a three-dimensional fabric having two fabric layers and a plurality of vertical yarns connected between the two fabric layers;
- guiding the three-dimensional fabric with the two fabric layers vertically in the horizontal plane to a coating space;
- applying an adhesive to the surface of the two fabric layers, and the adhesive spreading vertically and fluidly;
- and
- providing a reaction condition such that the adhesive dries into a film and forms a bonding layer.
An inflatable product, comprising a three-dimensional fabric having two fabric layers positioned up and down and a plurality of vertical yarns connected between the two such fabric layers, wherein the maximum distance between the two fabric layers when the three-dimensional fabric is expanded is limited by the length of the plurality of vertical yarns;
- and a cladding film surrounds the three-dimensional fabric, at least a part of the two edges of the cladding film corresponding to the two fabric layers, respectively, and being bonded to the ring of the three-dimensional fabric so that an inflatable space is defined between the three-dimensional fabric and the cladding film, when the inflatable space is filled with the air, the three-dimensional fabric is expanded and the two fabric layers are provided at the maximum distance from each other, wherein the two fabric layers correspond to a surface of the vertical yarn in sequence including:
- a bonding layer is formed by an air drying or heat drying adhesive, the adhesive material being a thermosetting polyurethane or a hot melt adhesive;
- and
- a combining layer is a waterproofing and air blocking fabric made of thermoplastic polyether polyurethane/thermoplastic polyester polyurethane, polyvinylchloride, rubber, or other elastomers.
