Study on the behaviour and comfort of reusable knitting suits of wool blends in the context of the Covid 19 pandemic

ABSTRACT

Nowadays, humanity is facing serious challenges due to the disruption of the COVID-19 pandemic, affecting dramatically our healthcare system along with the economic structure, social and cultural life. Healthcare personnel treating patients with infections like COVID-19 are exposed themselves to infection. Therefore, it is compulsory to be protected from contaminated body fluids using personal protective equipment (PPE). This equipment made of synthetic fibers proved to be uncomfortable. Therefore, we developed a reusable suit composed of a blend of wool and silk to be wear under full-body protective clothing aiming to improve their comfort and safety. Firstly, we focused on the analysis of some dimensional characteristics specific mass, porosity, thickness followed by comfort characteristics of knitted fabrics. Accordingly, the test methods comprise measurements for hydrophilic properties, air and water vapour permeability, thermal conductivity and dimensional stability to repetitive washing. After material analysis, a significant number of two-piece suits composed of blouse and trousers were industrially manufactured and delivered to healthcare personnel to be tested. The results are completed and supported with the perception of the healthcare staff involved in the study via a survey. Finally, the results and implications for future research are presented.
