Chapter Five in Wool Dyeing, titled Wool-Dyeing Machinery, includes an introduction and covers top dyeing, loose stock dyeing, hank dyeing yarn, yarn package dyeing, piece dyeing, garment dyeing, carpet piece dyeing, and dyehouse automation. During the 1980s, major developments in the design of wool dyeing machines occurred, particularly in automation. The shift away from fiber dyeing in loose stock and worsted top to downstream coloration significantly affected design trends. An increase in demand for quick response inventory control was responsible for the shift. Robotics are critical to tasks in which high capital investment is directly related to an increase in productivity and a decrease in labor costs. Environmental issues have also significantly affected design, particularly in water consumption and effluent disposal. Controlled liquor flow pressure and optimized drying procedures have reduced fiber damage. Radio frequency technology has become standard in wool drying systems based on conveyor belt dryers. 4 refs.
