A process of removing soil and/or stains from fabrics by immersing the fabrics in a peroxygen bleach bath containing as a peroxygen activator a carbodiimide of the formula: R.sub.1 --(X).sub.n-1 --N.dbd.C.dbd.N--(X').sub.n-1 --R.sub.2 wherein R.sub.1 and R.sub.2 each represent alkyl of 1 to 16 carbon atoms; cycloalkyl of 3 to 7 carbon atoms; phenyl; lower alkylphenyl; lower alkylnaphthyl; naphthyl and heterocyclic of 1 to 2 fused rings each having 5 to 6 members of which 1 to 2 are heteroatoms selected from the class consisting of nitrogen, oxygen and sulfur, it being provided that the aforesaid values of R.sub.1 and R.sub.2 may bear optional substituents selected from the group consisting of --NO.sub.2, --Cl, --Br, alkoxyl, amino, cyano, hydroxyl, --O--, --NH--, quaternary nitrogen, --SO.sub.3 H and --COOH. Also described are dry blend compositions containing the activator and peroxygen.
一种从织物中去除土壤和/或污渍的过程,通过将织物浸入含有过氧化物漂白剂的过氧化氢活化剂的浴中来实现,其中该活化剂为以下公式的羰基二亚胺:R.sub.1--(X).sub.n-1--N.dbd.C.dbd.N--(X').sub.n-1--R.sub.2,其中R.sub.1和R.sub.2分别表示1到16个碳原子的烷基;3到7个碳原子的环烷基;苯基;较低的烷基苯基;较低的烷基萘基;萘基和具有1到2个融合环的杂环,每个环具有5到6个成员,其中1到2个成员为从氮、氧和硫的类中选择的杂原子,所述的R.sub.1和R.sub.2的值可以带有选自--NO.sub.2、--Cl、--Br、烷氧基、氨基、氰基、羟基、--O--、--NH--、季铵盐、--SO.sub.3H和--COOH的可选取代基。还描述了包含活化剂和过氧化物的干混合物组合物。
