Latest Patents
Richard R Holt holds a patent for a dyeing method that enhances the fixation of dyes on keratinous fibers. This method involves impregnating the fibers with aqueous compositions containing dyes and subsequently storing them in a moist condition. By utilizing radio frequency heating to raise the temperature of the stored fibers, a higher level of dye fixation can be achieved. This process allows for the attainment of heavier shades using cheaper dyes. The optimal storage temperature ranges between 40°C and 80°C, requiring approximately 0.05 kWh/kg of fibers. Various types of dyes, including acid, milling, chrome, premetallized, reactive dyes, and substantive optical brighteners, can be employed in this method.
