Abstract:
A method of forming a textile article consisting of the steps of:providing air permeable and vapor permeable material having individual pores with a pore size in the range of 1 to 1.5 .mu.m, non-penetrable by allergens, and air permeable to allow a sealed construction without the article being prone to bursting when pressure is applied;forming from the air permeable and vapor permeable material a cover having top and bottom cover parts which overlie each other such that at least the edges thereof are adjacent each other;securing all but one, or at least a part thereof, of said edges together non-releasably;introducing a filling material into said article through said one edge, or said part thereof; and,non-releasably sealing said one edge, or part thereof, without breather elements for the release of interior pressure to form a textile article in which said sealed edges are not penetrable by allergens and the sealed construction is not prone to bursting when pressure is applied.
