Abstract
A foamed fabric comprising filaments of closed-cell foam of cross-linked polymeric material is formed by integrating the filaments into a precursor textile and subsequently foaming the material at a foaming temperature at which the filaments expand. The foamed fabric can be used for protective garments, pads, mats and the like.
Claims19
An unfoamed, woven precursor textile having a warp and a weft and comprising filaments of chemically cross-linked polymeric material, containing a chemical blowing agent, which, on subjecting to a foaming temperature of at least 150° C., expands by at least 5 times its volume to form a closed-cell foamed fabric.
A foamed fabric comprising a woven textile having a warp and a weft and filaments of chemically cross-linked polymeric material, which have been foamed to form closed-cell foamed filaments that extend out of a plane of the fabric in the form of open arches.
An unfoamed, woven precursor textile having a warp and a weft and comprising filaments of chemically cross-linked polymeric material, containing a chemical blowing agent, which, on subjecting to a foaming temperature of at least 150° C., forms a closed-cell foamed fabric, wherein the weight of the filaments is between 10,000 dtex and 50,000 dtex.
