Color Uniformity In a totally  automated environment where the possibility of human error has been eliminated, resin is transported from huge storage silos and mixed with color pigments and other performance additives.  The mixture is extruded into several different yarn colors and air-jet-entangled together to create a "heathered" multicolor blend.  At each step along the way, variables such as temperature, pressure and speed are continuously monitored by computer.  Process parameters are automatically adjusted when necessary to ensure absolute consistency.  Our painstaking attention to uniformity eliminates the possibility of carpet side match problems caused by uneven dying. To make sure they can withstand the rigors of real world spills, sunlight, and wet cleaning, our chemists subject the fibers to a gauntlet of laboratory tests and fadeometer hours.  Only the pigments that survive are used in Strudex carpet fibers.
