    摘要： The present invention relates to a textile washing agent, in particular a liquid textile washing agent, comprising a) at least one protease, wherein the protease has proteolytic activity and comprises an amino acid sequence which has at least 70% sequence identity with the amino acid sequence given in SEQ ID NO:1 over its entire length and, in each case based on the numbering according to SEQ ID NO:1, has (i) at the positions that correspond to positions 9, 130, 133, 144, 217, 252 and 271, amino acid substitutions, in particular the amino acid substitutions 9T, 130D/V, 133A, 144K, 217M, 252T and 271E, and (ii) at at least one, preferably at least two, of the positions that correspond to positions 6, 89, 131, 166, 189, 211 or 224, at least one additional amino acid substitution, in particular selected from 6W/F, 89A/G, 131H/Y/F, 166M/L/I, 189T/L/I, 211N/Q and 224A/G, more preferably selected from 6W, 89A, 131H, 166M, 189T, 211N and 224A, and b) at least one washing agent ingredient, preferably in an amount of from 0.01 to 99.9 wt.%, wherein the textile washing agent has a pH of from approximately 9 to approximately 12, measured in a 1 wt.% solution in deionized water at 20° C. The present invention also relates to corresponding methods for cleaning textiles, in which methods agents according to the invention are used, and to uses of agents according to the invention for removing protease-sensitive stains from textiles.

    摘要： A method of laundering fabric, where the method includes the steps of: (a) in a main washing step, washing soiled fabric with an aqueous wash bath including detersive surfactant and one or more of the following components: perfume, brighteners, hueing dyes, enzymes, or any combination thereof; and (b) in a rinsing step, rinsing the soiled fabric with an aqueous rinsing solution including photo-bleach; where an artificial light source is present and turned on during at least part of the rinsing step (b) and provides light to the aqueous rinsing solution in such a manner that activates the photo-bleach present in the aqueous rinsing solution, and where the artificial light source is turned off during at least part of the main washing step (a) and does not provide any light to the aqueous wash bath.
