Current methodologies for evaluation of antibacterial properties of traditional textiles are not applicable to foil-backed, poorly-absorbent electrospun nanofiber materials, since existing test methods require absorbent fabrics. Since electrospun nanofibers are adhered to the foil backing only by electrostatic interactions, methods used to evaluate antibacterial properties of surfaces cannot be used because these protocols cause the nanofibers to lift from the foil backing. Therefore, a novel method for measurement of the antibacterial properties of electrospun metallic foil-backed nanofiber materials was developed. This method indicated that acetate-based nanofibers manufactured to contain 5 to 30 weight percent of cold-pressed hemp seed oil or full-spectrum hemp extract inhibited the growth of Staphylococcus aureus in a dose-dependent manner, from 85.3% (SEM = 2.2) inhibition to 99.3% (SEM = 0.15) inhibition, respectively. This testing method represents an advanced manufacturing prototype procedure for assessment of antibacterial properties of novel electrospun, metallic foil-backed nanofiber materials.

箔衬电纺纳米纤维的抗菌性能测定

当前的评估传统纺织品抗菌性能的方法不适用于箔衬，吸收性差的电纺纳米纤维材料，因为现有的测试方法需要吸收性织物。由于仅通过静电相互作用将电纺纳米纤维粘附到箔衬板，所以不能使用用于评估表面抗菌性能的方法，因为这些协议会导致纳米纤维从箔衬板中提起。因此，开发了一种新的方法来测量静电纺金属箔支持的纳米纤维材料的抗菌性能。此方法表明，制造的醋酸盐基纳米纤维含有5至30重量％的冷榨大麻籽油或全光谱大麻提取物，其剂量依赖性地抑制了金黄色葡萄球菌的生长，从85.3％（SEM = 2.2）抑制到99.3％（SEM = 0.15）抑制。该测试方法代表了一种先进的制造原型程序，用于评估新型电纺丝，金属箔支持的纳米纤维材料的抗菌性能。
