Abstract

Textile structures with various bioactive and functional properties are used in many areas of medicine, special clothing, interior textiles, technical goods, etc. We investigated the effect of two different textile woven structures made of 90% polyester with 10% polyamide (PET) and 100% cotton (CO) modified by magnetron sputtering with copper (Cu) on bioactive properties against Gram-positive and Gram-negative bacteria and four viruses and also on the some comfort parameters. PET/Cu and CO/Cu fabrics have strong antibacterial activity against and . CO/Cu fabric has good antiviral activity in relation to vaccinia virus (VACV), herpes simplex virus type 1 (HSV-1) and influenza A virus H1N1 (IFV), while its antiviral activity against mouse coronavirus (MHV) is weak. PET/Cu fabric showed weak antiviral activity against HSV-1 and MHV. Both modified fabrics showed no significant toxicity in comparison to the control medium and pristine fabrics. After Cu sputtering, fabric surfaces became hydrophobic and the value of the surface free energy was over four times lower than for pristine fabrics. The modification improved thermal conductivity and thermal diffusivity, facilitated water vapour transport, and air permeability did not decrease.

摘要

具有各种生物活性和功能特性的纺织结构被应用于医学、特殊服装、室内纺织品、技术产品等许多领域。我们研究了两种不同的纺织编织结构的效果，一种是由90%聚酯纤维和10%聚酰胺（PET）制成，并通过磁控溅射镀铜（Cu）进行改性，另一种是100%棉（CO）通过磁控溅射镀铜改性，研究其对革兰氏阳性菌和革兰氏阴性菌以及四种病毒的生物活性特性，以及一些舒适参数。PET/Cu和CO/Cu织物对[具体细菌名称未给出]具有很强的抗菌活性。CO/Cu织物对痘苗病毒（VACV）、单纯疱疹病毒1型（HSV-1）和甲型流感病毒H1N1（IFV）具有良好的抗病毒活性，而其对小鼠冠状病毒（MHV）的抗病毒活性较弱。PET/Cu织物对HSV-1和MHV表现出较弱的抗病毒活性。与对照培养基和原始织物相比，两种改性织物均未显示出明显的毒性。镀铜后，织物表面变得疏水，表面自由能值比原始织物低四倍以上。这种改性提高了热导率和热扩散率，促进了水蒸气传输，且透气率没有降低。
