Patent ID: 11846065

Abstract:
A new method of delivering more precise amounts of carpet mill dye to regions of discoloration using a roller-ball applicator enables precisely metered delivery of the three primary dye colors to discolored carpet fibers. The method eliminates the need for a water extraction, enables the restoration of a more uniform color pattern, and eliminates dye overspray outside of the treated region that is inherent with the use of a spray bottle. The applicator is held with a loose grip and the roller ball is alternately moved in clockwise and counter-clockwise directions while in contact with the carpet fibers to be dyed. This ensures that dye is delivered to all sides of the fiber. To ensure even dye penetration and improved motion of the roller ball, an emulsifier is added to the dye solution. After each application, a microfilament cloth is wiped across the treated region.
