Definitions

  • the invention relates to a process for treatment of textiles by use of an enzyme and to a rinsing agent for use therein.
  • Treatment of soiled or unsoiled textiles normally comprises washing with a detergent containing anionic and/or nonionic surfactant, followed by rinsing and drying.
  • a detergent containing anionic and/or nonionic surfactant can be incorporated into the detergent to improve the removal of fat soiling (EP 130,064, EP 214,761 , US 4,810,414).
  • a non-dusting granulate containing a cellulase can be added to a main wash detergent composition in order to reduce the harshness of the laundry (US 4,435,307).
  • proteases are useful in detergent compositions in order to remove proteinaceous stains (US 3,723,250), and that amylases are useful in detergent compositions in order to remove starchy stains (US 3,627,688 and 4,548,727).
  • a given enzyme may be incompatible with a given detergent composition due to unsatisfactory activity and stability of the enzyme, and this imposes some limitations in the choice of enzyme and detergent formulation. It is the object of the invention to provide an alternative method of using enzyme in textile treatment, so as to obtain efficient enzyme effects for a given enzyme dosage while avoiding the above limitations.
  • an enzyme provides a better enzymatic effect when used in the rinse liquor than when used as a constituent of the main wash composition.
  • the effect is particularly pronounced after repeated cycles of washing, rinsing and drying.
  • Detergent is essentially absent during rinsing, and thus compatibility problems are avoided.
  • the enzyme may advantageously be added in the last rinse step together with a fabric softening and/or antistatic agent.
  • the invention provides a process for treatment of textiles by use of an enzyme, characterized by the fact that the enzyme is used in a rinse liquor for a rinsing step after washing.

  • the invention comprises a rinsing agent for use in the process according to the invention, this rinsing agent being characterized by the fact that it is an enzyme preparation stabilized against microbial infection.

It is intended that this rinsing agent is added to the rinse liquor, both providing the proper concentration of enzyme and the proper amount of fabric softening agent and/or antistatic agent.
  • the enzyme is cellulase
  • the softening agent and the antistatic agent is a cationic surfactant
  • the rinsing agent contains additionally a non-ionic surfactant.
  • Lipases of plant or animal origin can be used in the invention, but microbial lipases are preferred for reasons of economy.

Abstract

Dans le procédé décrit on utilise une enzyme dans un liquide de rinçage lors de la phase de rinçage une fois le lavage terminé. L'agent de rinçage est une préparation à base d'une enzyme, stabilisée pour résister aux infections microbiennes. L'utilisation de l'enzyme dans le procédé procure un meilleur effet enzymatique lorsqu'elle est utilisée dans le liquide de rinçage que lorsqu'elle est présente comme constituant de la composition de lavage principale.
