TS 193.2
 In order to enable the textile and the users to avoid microbial disoperation, sixteen/eighteen tertiary amines and γ-chloropropyl trimethoxy siloxane are adopted to prepare antibacterial agent GD-2 and then antibiotic finish is performed on pure cotton fabrics. The technology of synthesis and application are also studied.The optimal synthesis technology is as follows:sixteen/eighteen tertiary amines:γ-chloropropyl trimethoxy siloxane:ethyl alcohol=1:1.1:2, at 80℃ for 36h. And the appropriate application technology conditions are:usage amount of GD-2 is 20g/L, pH=6, pre-baking and baking temperature are 80℃ and 120℃, respectively. Antibacterial rate towards Escherichia coli and Staphylococcus aureus are 99.74% and 99.37%, respectively.
