Under conditions of misuse, water-soluble peroxyacids when they are left in direct contact with dyed fabrics can cause spotting and dye damage. The problem can be ameliorated by surface-treating the peroxyacid with an effective amount, preferably selected in the range of 8 to 25% w/w based on the peroxyacid, of aliphatic amines which melt or soften at about 30 to 70°C. Preferred agents include hydrogenated tallow amine dicocoamine and methyl dihydrogenated tallow amine. The agent can be applied in molten fashion or in inert solvent such as a chlorinated aliphatic hydrocarbon onto agitated particles of the peroxyacid.
在使用不当的情况下,
水溶性过氧酸与染色织物直接接触会造成斑点和
染料损伤。 可以用有效量的脂肪族胺对过氧酸进行表面处理来改善这一问题,脂肪族胺在 30 至 70°C 的温度下会熔化或软化,有效量最好为过氧酸的 8% 至 25% w/w。 首选的药剂包括氢化牛脂胺二可可胺和甲基二氢化牛脂胺。 可以将药剂以熔融方式或在
氯化脂肪族烃等惰性溶剂中涂抹在过氧酸的搅拌颗粒上。
