Latest Patents

Shaw's most notable patent is titled "Method of dyeing a corespun yarn and dyed corespun yarn." This inventive method addresses the challenges of dyeing a corespun yarn, which consists of an inorganic fiber core and at least one sheath. The process he developed involves several steps: contacting the corespun yarn with a dye liquor, heating the liquor to an appropriate dyeing temperature for optimal effectiveness, cooling the dye liquor at a controlled rate, and finally rinsing the yarn with water or a mixture of dye liquor and water. The resulting dyed corespun yarn maintains approximately 80% or more strength retention based on the undyed counterpart, allowing for the creation of uniformly dyed and high-strength yarns. Noteworthy features include the absence of significant “grin through” effects and minimal yarn strength loss after the dyeing process.
