Abstract

The present invention concerns the use of enzymes for improving water absorption and / or improving whiteness of a textile. The invention further concerns a softener composition for use in improvement of water absorption and / or improvement of whiteness of a textile.

Description

technical field [0001] The present invention relates to the use of enzymes, in particular cellulases, for improving the water absorption and / or improving the whiteness of surfaces, such as textile surfaces, wherein the use is in softeners. [0002] References to Sequence Listings [0003] This application contains a Sequence Listing in computer readable form. Said computer readable form is incorporated herein by reference. Background technique [0004] The use of enzymes in laundry detergents is well known. Furthermore, it is known to use enzymes capable of degrading cellulosic materials for laundry purposes. However, laundry cellulolytic enzymes should be chosen carefully, since laundry textiles serve as substrates for the enzymes. [0005] In washing machines, the degradation of cellulosic materials is often a challenge. During washing with enzymes that degrade cellulosic material, cellulose fibers may be removed from textiles and often clog filters, pipes and drains ...
