摘　　要：采用甲酸预处理和铝单宁交联的方法对超细纤维合成革进行改性,以提高超细纤维合成革的染色性能及透水汽性。通过考察甲酸用量、甲酸预处理时间、铝单宁用量、交联时间、交联温度及改性pH值等因素对合成革基布上染率及透水汽性的影响,优化了预处理和铝单宁交联的工艺条件,即:甲酸用量3%、预处理时间60 min、铝单宁用量6%、交联时间60 min、交联温度50℃、交联pH值为6。Modification of superfine synthetic leather is carried out by the method of formic acid pretreatment and aluminum tannin crosslinking to enhance the dyeing behaviors and water vapor permeability.Influences of dosages of formic acid and aluminum tannin,pretreatment time,crosslinking time and temperature,as well as pH value on dye uptake and vapor permeability of the modified synthetic leather are investigated.Optimized conditions are defined as follows： pretreatment with 3% formic acid for 60 minutes,and crosslinking at 50 ℃ for 60 minutes with 6% aluminum tannin and pH value 6.
