Development of durable antibacterial knitted polyester fabrics by incorporation of small proportion of polyester-silver nanocomposite fibres has been attempted in this research. Polyester-silver nanocomposite fibres are blended with normal polyester fibres at three weight fractions (10, 20 and 30%). Three parameters, namely blend proportion (wt.%) of nanocomposite fibres, yarn count and knitting machine gauge, have been varied for producing 27 knitted fabrics. Knitted fabrics prepared from polyester-silver nanocomposite fibres show good to excellent antibacterial activity (65-99%) against both S. aureus and E. coli bacteria. Blend proportion of nanocomposite fibres is found to be the most dominant factor in influencing the antibacterial activity of knitted fabrics. Antibacterial activity also increases with coarser yarn count and higher knitting machine gauge. It is also found that the tightness or compactness of knitted fabrics is correlated positively with their antibacterial activity.

聚酯银纳米复合纤维抗菌针织物的开发

通过掺入少量聚酯-银纳米复合纤维的尝试，开发出了耐用的抗菌针织聚酯织物。将聚酯-银纳米复合纤维与普通聚酯纤维以三种重量分数（10％，20％和30％）混合。改变了三个参数，即纳米复合纤维的混纺比例（wt。％），纱线支数和针织机规格，以生产27种针织面料。由聚酯-银纳米复合纤维制成的针织物对金黄色葡萄球菌和大肠杆菌均表现出良好至优异的抗菌活性（65-99％）菌。发现纳米复合纤维的混纺比例是影响针织织物抗菌活性的最主要因素。随着纱线支数的增加和针织机规格的提高，抗菌活性也会增强。还发现针织物的紧密度或紧密度与其抗菌活性呈正相关。
