Definitions

  • the present invention is in the field of enzyme technology, in particular the anti-pilling effect of enzymes, such as those used in detergents or cleaning agents.
  • the invention relates to agents, in particular washing or cleaning agents, which contain a polyesterase as defined herein. Furthermore, the present invention relates to a method for cleaning textiles and the use of the agent according to the invention for removing dirt. Furthermore, the invention relates to the use of a
  • Polyesterase as described herein, for reducing pilling effects and anti-gray in an agent, preferably a detergent or cleaning agent.
  • Pilling is the term for the formation of nodules or lint in fabrics. These small lint are particularly common with short-fiber fabrics. With long-fiber and twisted fibers, however, there is less pilling. In general, 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 more than natural fibers, because synthetic fibers can be released from the fabric faster than rough natural fibers. In the case of woolen fabrics, these fibers “matt” mainly through mechanical friction and form nodules on the surface.
  • Pilling takes place in particular at places that are subject to high mechanical stress, usually in the shoulder and waist region. Due to the continuous thinning of the material, these stressed areas are particularly at risk of forming holes or even tearing. The unwanted pilling has the consequence that the textiles are impaired accordingly
  • polyesterases can be significantly increased if they are fused with special peptide anchor molecules which have binding affinity for polyester. This effect was demonstrated here with an exemplary polyesterase, but is also transferable to other enzymes.

Abstract

L'invention concerne le domaine de la technologie enzymatique, en particulier l'effet antiboulochage des enzymes telles qu'utilisées par exemple dans des détergents ou des produits de nettoyage. L'invention concerne des agents, en particulier des détergents ou des produits de nettoyage renfermant une polyestérase telle que définie selon l'invention. L'invention concerne également un procédé pour nettoyer des textiles, ainsi que l'utilisation de l'agent selon l'invention pour supprimer des salissures. La présente invention se rapporte en outre à l'utilisation d'une polyestérase telle que décrite ici pour réduire les effets de boulochage et de grisaillement, dans un agent, de préférence un détergent ou un produit de nettoyage.
