Title: Innovations by Randy J Rawlston
Introduction
Randy J Rawlston is an accomplished inventor based in Hixson, TN (US). He holds 2 patents that showcase his expertise in the field of textile treatment and dyeing processes. His innovative methods have significantly contributed to the enhancement of nylon fibers.
Latest Patents
One of his latest patents is a "Method for providing protective treatment to nylon fibers." This invention outlines a method for reacting various protective entities to form covalent bonds with nylon. These entities can be applied directly in the dyebath with dyes used for nylon without blocking or interfering with their color yield. The protective entities include stain-blockers, chlorine resist agents, fire retardants, UV absorbers, antimicrobial agents, fume fade protectors, soil-resist agents, and anti-stats. The method involves reacting a protective entity with a moiety capable of forming a covalent bond with nylon fibers, creating a modified protective entity that can bond with nylon. This modified entity is then added to a dyebath containing selected dyes, applied at a specific pH range.
Another significant patent is the "Method of dyeing nylon to produce colorfast fiber which resists further dye." This method focuses on dyeing cationic dyeable Type 6 and 66 nylon to ensure that the dyed fiber resists further dye uptake and maintains high wash and bleed fastness. The process includes using a bifunctional dye solution with a very low pH and applying it to the fiber with a wet pick-up exceeding 100% by weight. The fiber undergoes steaming, washing, drying, and contact with an alkaline solution before being autoclaved. This innovative approach allows for the combination of dyed and undyed nylon fibers in textile products without the risk of bleeding or washout.
