  • the invention is directed to the use of a cutinase for reducing pilling effects and anti-gray in an agent, preferably a washing or cleaning agent.
  • Pilling refers to the formation of nodules or lint in fabrics. These small lint arise especially with short-fiber substances. With long-fibered and twisted fibers, pilling is less pronounced. Generally, these nodules are caused by loose fibers in the fabric or those that have come loose from the fabric. Due to their smooth surface, synthetic fibers tend to pilling rather than natural fibers because synthetic fibers can be released from the fabric faster than rough natural fibers. In woolen fabrics, these fibers "matt” mainly by mechanical friction and form nodules on the surface.
  • Pilling takes place especially on mechanically stressed areas, usually these are shoulder and waistband area. Due to the continuous thinning of the material, these stressed areas are in particular at risk of forming or even breaking holes.
  • cellulases are used in the detergent to reduce the pilling effect (DE 69632910 T3). This means that cellulases are used in the detergent to anti-pilling or anti-gray effect to ensure that clothes look like new. Cellulases, however, work exclusively on cotton textiles. For other textiles, such as polyester textiles, there is no comparable way to reduce pilling. Therefore, it is desirable and there is a demand for solutions that reduce the pilling of textiles, especially textiles containing synthetic fibers such as polyester.
  • a Cutomonase from Thermomonospora curvata DSM 43183 exhibits an anti-pilling effect in the washing process. Compared to detergents without cutinase / PET esterase, pre-pilled tissue or new tissue is less pilled after 20 washes with a detergent containing the cutinase according to the invention.
