Role of fabric properties, moisture and friction in transfer of bacteria from fabric to fabric

With increasing reports of textiles serving as vectors for the transmission of infections, it is crucial to study the factors influencing such transfers. This is of concern in various sectors, including healthcare and hospitality, where fabrics constitute an integral part. A better understanding of the fabric types that discourage microbial transfer could help to formulate guidelines for uniforms and other apparels in these sectors. This study aimed to assess the transferability of bacteria from fabrics considering the following factors: fibre and fabric type, moisture and friction. The transfer of bacterial genera important in healthcare settings was quantified with and without application of friction: Escherichia coli and Acinetobacter calcoaceticus from seven different fabrics (cotton, silk, viscose, wool, polyester, polypropylene and a polyester-cotton blend). Amongst the fabrics, transferability was observed to be maximal in polyester followed by viscose, while polypropylene showed the least transfer. Transfer of bacteria was favored by moisture and the application of friction. The study brings forth a correlation between fabric type and the transfer of bacterial cells between fabrics.
