Abstract

The invention relates woven and knit materials with an incorporated particulate solid and to a process for producing woven materials incorporated with a particulate solid. The process comprises: with a particulate solid. The process comprises: entraining a particulate solid in a gaseous carrier;
disposing one face of a woven material in the path of a stream of said gaseous carrier and entrained particulate solid; maintaining a pressure drop across the woven material from said one face to the other face of said material, thereby to obtain a woven material with at least some of the entrained particulate solid in the gaseous carrier; and fixing the incorporated particulate solid.
