The endurance of polyester threads is well known. They can withstand industrial cleaning procedures, heavy-duty detergents, bleaching and stonewashing. Viscose threads, due to their natural raw materials, allow the use of standard detergents that do not contain bleaching agents. However, both threads can withstand high washing temperatures of 95 °C and viscose has a better resistance to high ironing temperatures.
Because of their robustness, polyester threads are often the best choice for uniforms, workwear, bedding, children’s clothing, towels, white textiles, outerwear, swimsuits, jeans with a worn look and other products that must be bleached, or need to withstand harsh chemicals or commercial laundering. Viscose is also suitable for corporate fashion, but only when no bleaching is necessary. However, this is often not possible for colourful materials anyway.
Tip: Madeira Polyneon embroidery threads have a superior resistance to chlorine, and denim wash treatments are possible.
