| 摘要 |
A chemical cleaning system for a multi-tank or a single-tank laundry washing machine, having at least two separate components for aqueousdissolution or dilution to respective use concentrations, a first component comprising a proteolytic enzyme, and a second component comprising an imidoperoxycarboxylic acid, particularly phthaloylaminoperoxycaprbic acid (PAP), wherein the first component is introduced into a prewash zone or step, and the second component is introduced into a main wash zone or step. When using this system, it was found that effective cleaning could be obtained even at relatively low main wash temperatures of 45-55° C.As a result, much less energy was needed and a considerable reduction of textile damage was observed as compared with cleaning systems of the prior art.
