DYED OLEFIN YARNS AND TEXTILE FABRICS USING SUCH YARNS

摘要

A novel olefin fiber or yarn, textile fabric or film is manufactured using olefin that contains variable amounts of a unique dyeable concentrate additive including relevant amounts of amorphous nylon and nylon 6 and/or nylon 66. Fabrics, fibers, yarns and films made according this invention can be processed using conventional nylon dyeing systems carried out at atmospheric pressure. The dyeable concentrate additive can be easily dosed into a conventional fiber or film extruder or can be formed into blended pellets which can be extruded into olefin fiber or film dyeable at atmospheric pressures. Multiple tones of a color can be dyed in a single dye bath by using different amounts of dyeable concentrate in different yarns or fibers. This invention is of particular value in the apparel, carpet, home furnishings and soft signage industries. Significant energy savings may be realized in carrying out the dyeing processes at atmospheric pressures.
