A microbiological evaluation of SiO₂-coated textiles in hospital interiors: The effect of passive coatings on the cleaning potential of interior textiles

Abstract

The use of passive coatings could be a new solution to improve the cleaning potential of interior textiles in hospitals. In these years, the scepticism toward the use of antibacterial textiles in the health care sector is emerging, and in the Nordic countries, the implementation success is confined. From this perspective, the purpose of this paper is therefore to address focus on alternative passive coatings that without actively killing the bacteria provide a hydrophobic and easy-to-clean textile surface. The paper relates to an in-situ study evaluating the effect and cleaning potential of SiO2-coated textiles compared to traditional textiles and a hard plastic surface as a reference material. Through the study, arranged at an outpatient lung department at Hospital Vendsyssel, Denmark, five different surface materials were installed on hospital chair armrests and sampled with microbiological contact plates through a three-week period. By determining the level of contamination on these surfaces, the study illustrates that the SiO2-coated textile is possible to clean to an acceptable level below the critical limit value of 2,5 Colony Forming Units (CFU) per cm2. In comparison, the traditional textiles were only cleaned to the acceptable level in 56% of the microbiological controls, while the regular hard plastic surface only had acceptable levels of contamination in 25% of the samplings.

ANTIBACTERIAL EFFICIENCY OF MODAL FABRIC TREATED WITH OXIDES OF Ti/Si/Zn NANOCOMPOSITES

“…9 Nano SiO2 treated textiles have provided better microbiological controls in hospital interiors. 10 A significant result was observed in the zinc oxide nanoparticle treated cotton fabrics against S.Aureus. 11 In the ZnO/TiO2 composite treated nylon/cotton blended fabric, the highest antibacterial property against E.coli and S.Aureuswas obtained at a concentration of 60 ppm.…”

Development of Highly Hygienic Textile by Coating with Encapsulated Ginseng Oil

“…The functionalization of textile products for use as personal protective equipment (PPE), filters, sensors, clothing, interior materials, and so on is being actively pursued in various industries, such as hygiene, interior design, and medical care, using fiber as the substrate [1][2][3]. In particular, owing to the recent COVID-19 pandemic, the development of PPE products is needed to protect the human body from external bacteria or viruses and harmful substances.…”

Evaluation of biofilm formation on acrylic resin surfaces coated with silicon dioxide: an in situ study

“…12 Nanoscale silicon dioxide has been used in hospital environments. 13 Silicon dioxide coating results in a surface with a massively reduced amount of microorganisms and is easy to clean. In addition, silicon dioxide has been shown to be effective in reducing the adhesion of C. albicans to acrylic resin surfaces 14,15,16 and a recent in vivo study has demonstrated a high level of tissue biocompatibility of acrylic resin coated with silicon dioxide with low deleterious risk to patients.…”
