摘　　要：采用银氨溶液原位还原法制备稳定的、抗菌性持久的棉织物。通过探讨银氨溶液浓度、处理温度、处理时间等因素对银负载量的影响,并与AgNO3溶液处理棉织物作比较,测试含银抗菌织物的抗菌性能和断裂强力,结果表明,棉织物负载银的合适工艺为:温度80℃,银氨溶液浓度2 mmol/L,反应时间90 min。在相同条件下,棉织物银氨溶液处理后的表面银的负载量高于硝酸银溶液;利用该法制备的抗菌棉织物具有优良的抗菌性,经过50次标准洗涤后,抗菌棉织物仍具有优良的抗菌性;抗菌处理后,对织物的断裂强力影响很小。The stable and durable anti-bacteria cotton fabrics are prepared with silver ammonia solution by in-situ reduction method. The influences of the concentration of silver ammonia solution, reaction temperature and time on the loading nano silver of cotton fabrics are investigated, and compared with the fabric treated with silver nitrate solution. The antibacterial properties and tensile strength of the silver-containing antibacterial fabric are tested. The results show that the optimized process of loading sil- ver on cotton fabrics are as follows： silver ammonia solution 2 mmol/L, reaction at 80℃ for 90 rain. The loading contents of sil- ver treated with silver ammonia solution are higher than that with silver nitrate solution under the same conditions. The cotton fabrics prepared with this method have good anti-bacterial properties even after .50 cycles laundering and good tensile strength.
