Abstract
A yarn is prepared from a mixture of textile staple fibers and active carbon staple fibers which consists of 5 to 75%, preferably 20 to 40%, of the latter by weight, by chopping active carbon monofilaments into staple fibers, mixing them with textile staple fibers in a liquid vehicle, separating the fibers from the liquid vehicle and spinning them to yarn which can be used in weaving fabrics of tensile strengths of as much as 2000 newtons per 5 centimeters, which in turn can be used in making filters and protective suits.
