Abstract:

In order to facilitate the industrial production of antibacterial, moisture absorption and swea transport polyester knitted fabric, organic silicon quaternary ammonium salt AEM 5700 was used for antibacterial finishing, and hydrophilic reagent SE was applied to improve moisture absorption and swea transport of the fabric. The performances of AEM 5700 were analyzed by infrared spectrometer and thermogravimeter. By testing the bacteriostatic rate and contact angle of the fabrics, the influences of baking temperature, baking time and drying temperature to the finishing effect were discussed. Moisture management tester was used to measure the moisture absorbency and sweat transport property of the fabrics. The results indicated that the optimum heat treatment process for AEM 5700 treating moisture absorption and sweating polyester knitted fabric is. drying at 80 ℃ and curing at 160 ℃ for 1 min. The bacteriostatic rate of the fabrics finished by the process is still 93.40% after 10 cycles of strong washing (equal to 50 times home laundering), and hydrophilic reagent SE could offset the declination of hydrophilicity of the fabrics.
