Effect of Cu Modified Textile Structures on Antibacterial and Antiviral Protection

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 Staphylococcus aureus and Klebsiella pneumonia. 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.

Porcupine-inspired microneedles coupled with an adhesive back patching as dressing for accelerating diabetic wound healing

“…It may be contributed to the effect of Cu 2+ on the surface of bacteria, which can damage the membrane of bacteria to achieve antibacterial effects [49] . More interesting, CaO2-HA NPs exhibits excellent antibacterial properties with or without NIR light.…”

Synergistic antibacterial attributes of copper-doped polydopamine nanoparticles: an insight into photothermal enhanced antibacterial efficacy

“…When treating S. aureus with samples of the same concentration, the diameters of the inhibitory zones were 3.39 mm (figures 6(B) and (D))). Cu@PDA NPs containing Cu 2+ showed better antibacterial ability than those without Cu 2+ , which may be attributed to the effect of Cu 2+ on the surface of bacteria that can damage the bacterial membrane and achieve antibacterial effects [42] .…”

Use of copper-functionalized cotton waste in combined chemical and biological processes for production of valuable chemical compounds

“…7 Most research is focused on the development of textile materials with antibacterial and antiviral properties. 8–16 One interesting method is the use of metallic particles, including copper and its compounds and complexes. 17–19…”

“…7 Most research is focused on the development of textile materials with antibacterial and antiviral properties. [8][9][10][11][12][13][14][15][16] One interesting method is the use of metallic particles, including copper and its compounds and complexes. [17][18][19] Copper compounds are among the bioactive modiers most widely used to functionalize textiles.…”

“…Electronic textiles can also be used in agro-textiles and functional accessories. 12,[46][47][48][49] There are currently no studies dedicated to copper functionalised cotton waste treatment methods. This is probably related to the general problem of separating special textile streams from waste.…”
