Abstract
An openwork textile structure is formed from at least one textile web and has a plurality of regularly and/or randomly distributed open areas wherein each open area is separated from the adjacent open area by at least one compressed zone of textile materials contiguous with at least one zone of textile materials having a greater apparent diameter than the compressed zones, and wherein the textile materials of the web remain parallel to one another in the compressed zones. Three-dimensional openwork textile structures can be formed by superimposing two or more of the openwork textile webs and gathering together and compressing in parallel arrangement, textile materials from at least two adjacent superimposed webs. The openwork textile structures can be prepared by holding a web of crimped textile materials under tension, locally compressing the web at a plurality of locations along the length and width thereof and thereafter relaxing the tension or by holding in place a web of non-crimped, but heat crimpable, textile materials, compressing the web at a plurality of locations along its width and length and thereafter heat treating the web, in the absence of tension, to develop the la…
