摘要
将不同浓度的纳米银复合抗菌剂喷施在鞋里革上,对其进行抗菌处理,以大肠杆菌、金黄色葡萄球菌、黑曲霉、粘性红圆酵母为供试菌种,采用抑菌率法评价其抗菌效果,同时通过干擦、湿擦、水洗及浸汗试验来考察抗菌鞋里革的抗菌持久性。试验结果表明:当纳米银粒子浓度为2.4×10-5、2.16×10-5和1.92×10-5g/mL时,抗菌鞋里革的抗菌持久性良好,在干擦25次、湿擦20次、水洗10次、汗液浸泡6次后,其对霉菌、细菌及酵母菌的抑菌率仍大于80%。从实际应用角度出发,确定纳米银复合抗菌鞋里革的处理工艺为:以纳米银粒子浓度为1.92×10-5g/mL的纳米银复合抗菌剂按70g/m2均匀喷施至皮样肉面;纳米银粒子浓度为1.92×10-5g/mL的纳米银复合抗菌剂∶U97038聚氨酯水乳液=1∶1(w/w)配成混合液,按60g/m2均匀喷施至皮样粒面,这样处理的纳米银复合抗菌鞋里革有较低的处理成本和较高的抗菌持久性。
The nano silver Composite antibacterial agent with different concentration were sprayed on shoe lining leather. The inhibitory effects of treated shoe lining leather on escherichia coli, staphylococcus aureus, aspergillus niger and rhodotorula muci- laginosa were evaluated by the bacteriostatic rate method. And the antibacterial durability were investigated by the dry and wet rubbing test, washing and sweat soaking test. The results indicate that the antibacterial shoe lining leather shows a good perform- ance on antibacterial durability with the silver concentration of 2.4 ×10^-5g/mL, 2.16 ×10^-5g/mL and 1.92×10^-5g/mL. The bacteriostatic rate of molds, bacteria and saccharomycetes is still more than 80% after dry rubbing 25 times, wet rubbing 20 times, washing 10 times and sweat soaking 6 times. From the view of practical applications, the disposed method of antibacterial shoe lining leather is as follows： the nano silver composite antibacterial agent （ 1.92 ×10^-5g/mL） is sprayed on the flesh side of leather by 70g/m2. The mass ratio of nano silver composite antibacterial agent （ 1.92 ×10^-5g/mL） and U97038 polyurethane is 1：1, and the mixture is sprayed on the grain side of leather by 60g/m2. The shoe lining leather treated by the method has a low - cost and high antibacterial durability.
