U.K.-based chemical company Venator reports that it has developed a new liquid pigment masterbatch technology that can be used to brighten recycled polyethylene terephthalate (PET) fibers quickly, cleanly and efficiently. Based on the company’s established titanium dioxide (TiO2) platform for the fiber industry, the new Hombitan® LQ range is optimized for delustering PET fibers from plastic bottles that are re-spun into polyester – ready for the manufacture of new consumer products such as footwear and apparel. Venator will launch Hombitan® LQ White 100, optimized for semi-blunt recycled PET fibers, and Hombitan® LQ White 130 for the production of fully blunt fibers, both designed for smaller projects using recycled PET on a single extrusion line. According to Venator, they are easy to use and offer several advantages over solid (pelletized) masterbatch pigment solutions, including ease of incorporation into an extrusion line, resistance to temperature fluctuations and pressure variations during processing, and the fact that no pre-processing is required – saving fiber producers time and money. Unlike pelletized masterbatches, which must be dried and crystallized, Hombitan® LQ products are supplied ready-to-use in easy-to-store drums and can also be used near spinning operations thanks to their liquid formulation.
