ABSTRACT:
A flotation fabric is composed of two opposed layers of water permeable flexable woven or knitted material. Sandwiched between the layers are small particles, pellets or beads of closed cell foam plastic material. The cloth layers are joined together by stitching, heat sealing or adhesive to trap and flexibly immobilized the pellets between the layers to form a breathable flexible flotation fabric. Personal flotation devices or garments such as T shirts are made from the fabric. They are light weight, flexible, breathable and comfortable enough to be worn by a child at play and will allow a child to return to the surface and cry out for help to prevent drowning if the child falls in a body of water.
