Soil and/or stains are/is removed from fabrics by immersing the fabrics in a peroxygen bleach bath containing as a peroxygen activator an N-sulfonyl-azole of the formula:
where Z represents the number of carbon and nitrogen atoms necessary to complete a pyrazole, pyrrole, triazole, or benzotriazole ring, in which the ring can be substituted with phenyl, C1-10 alkyl, halogen, amino, cyano, nitro or C1-10 alkoxy and R is a C1-10 alkyl radical.
Peroxygen-containing compositions contain a peroxygen compound and an N-sulfonylazole compound as defined above and may also optionally contain one or more of a detergent, water, a buffering agent and a detergency builder.
将织物浸泡在含有过氧活化剂 N-磺酰基唑的过氧漂白浴中,可去除织物上的污垢和/或污渍:
式中 Z 代表完成
吡唑、
吡咯、三唑或苯并三唑环所需的碳原子和氮原子数,其中环可被苯基、C1-10 烷基、卤素、
氨基、
氰基、硝基或 C1-10 烷氧基取代,R 为 C1-10 烷基。
含过氧化合物包含过氧化合物和如上定义的 N-磺酰基唑化合物,还可选择包含一种或多种洗涤剂、
水、缓冲剂和去污剂。
