Abstract (en)
[origin: WO9626999A1] The present invention relates to the use of a liquid composition comprising a peroxygen bleach and a compound chelating copper and/or iron and/or manganese, for pretreating fabrics before said fabrics are washed, whereby the loss of tensile strength in said fabrics is reduced. The present invention further encompasses a process for pretreating soiled fabrics as well as compositions suitable to be used in said process.
