Apart from the antibacterial performance, wearability and durability are also important factors for the textile product quality. The paper mainly discusses the wearability and durability of bamboo pulp and cotton-knitted fabrics which were treated with alkali and copper ammonia solution. Washing fastness, release properties of copper ions when washing, bursting properties, abrasion resistance, permeability, moisture penetrability, and warmth retention properties of fabrics were tested to investigate the change after copper ammonia solution treatment. The results showed that although the release quantity of bamboo pulp fabrics was higher, the washing fastness of bamboo pulp fabrics was better than that of cotton fabrics. After 90 times’ washing, the copper ion complex fabrics still had good antibacterial performance. For both cotton and bamboo pulp fabrics, properties of the bursting strength, moisture penetrability and warmth retention had been improved, whereas properties of abrasion resistance and air permeability had receded. 相似文献

Silver compounds have extensive use among the antimicrobial agents in textiles. Silver particles are released into the water during washing processes in particular and they are released from the textile in time due to use. In this work, silver ion release from cotton and polyester antimicrobial fabrics which are the most widely used textiles have been studied. Two well-known silver-based commercial agents and silver-doped calcium phosphate powder-based antibacterial finishing agent which was developed in our previous work were applied to the fabric samples. The release of silver from the fabric samples during washing and incubation was determined by ICP-OES. The effects of fabric composition, time and laundering process on the silver release were studied. It was found that significant amount of silver was released from textile fabrics during washing due to the mechanical forces exerted on the fabrics. The total released silver varied from 73.43 to 92.27% for cotton fabrics and 76.49 to 89.70% for PES fabrics after 20 washing cycles. Results also showed that calcium phosphate can reduce the amount of silver release significantly. It was also found that even a smaller quantity of nanosilver particles was sufficient for strong antibacterial activity. 相似文献

为考察抗菌织物的耐洗性及皮肤刺激性,以经纳米银整理的抗菌丝织物为实验对象,采用琼脂平皿扩散法和吸收法对其抗菌性能进行定性和定量实验,采用电感耦合等离子体质谱仪(ICP-MS)测定样品的金属溶出量,同时利用EPI-MODEL人体皮肤模型,对织物水萃取液的皮肤刺激性进行初步研究。结果显示:在洗涤50次后,样品对大肠杆菌8099和金黄色葡萄球菌ATCC6538的抗菌率依然在99%以上,具有良好的耐洗性能;织物水萃取液对皮肤无刺激性,较为安全。 相似文献
