Abstract
Methods and devices to actively apply finish to one or more yarns in motion at speeds greater than about 3000 m/min, to achieve a finish application of 0.2 wt % or more with a coefficent of variation of finish concentration of 10% or less, and the finished yarns so produced. The devices are compact, portable and readily installed at a variety of positions on a fiber processing line, such as between heated godet rolls. The devices contain the finish so that contamination of the surrounding areas is prevented. The yarn products of the invention may be used in textile and leisure fiber applications and in industrial fiber applications, such as tires.
