Dr. Knight


A guardian with a code of honor. ‘’While creating Dr. Knight laundry machine color catcher our team was operating under one credo – Make it clean while being green! And with the respect of the code of honor amazing midnight blue hydrogel balls were created together with new reinvented “Knight helmet” laundry ball.’’


Dr. Knight ltd. is developing new, completely ‘’green’’ polymer material to help people in preventing dying of their clothes during laundry. Unlike other alternatives ‘Dr. Knight is bringing completely new patented material and technology on the market which introduce eco-friendliness, reusability, efficiency, multi use and functional design. Polymer is completely made of renewable resources, where one of them is waste from the seafood industry. By making Dr. Knight with simple procedure, on ambient pressure and temperature, we created product that contributes to sustainability, circular economy and health. It could be used in households as a color catcher that prevents dyeing clothes during the washing process as well as on industry scale as part of wastewater treatment equipment.
