Degree of chitosan deacetylation on thermophysiological comfort properties of nylon 6,6 fabrics

Abstract

The purpose of this paper is to analyze the effects of treatments using chitosan in different degree of deacetylations (DDs) on thermophysiological comfort properties of nylon 6,6/elastane pressure garments using a large skin model hot plate instrumentation to prevent infection and excess sweating during burn scar management for future designs.Design/methodology/approachChitosans in different DD (DD 70, DD 81 and nylon 6,6/elastane fabrics in different structures, then the total DD 90) are treated with thermal resistance (Rct) ((°ΔC)(m2)/W), total heat loss (Qt or THL) (W/m2), apparent total evaporative resistance (RetA), ((ΔkPa)(m2)/W), apparent intrinsic evaporative resistance (RefA), ((ΔkPa)(m2)/W) and total insulation values (It) (clo) were analyzed using the large skin model hot plate instrumentation in comparison with untreated control samples. Antimicrobial activities, washing tests and moisture regain properties were also evaluated.FindingsIt is found that chitosan DDs have a significant effect on thermophysiological comfort properties of nylon 6,6 fabrics. A small but statistically significant decrease was observed in thermal resistance (Rct) (Tog) and isolation (It) (clo) properties for higher chitosan DDs and for higher chitosan concentrations for all fabric samples after each treatment. Antimicrobial activity showed a small but statistically significant decrease for all samples with the increase of DD and fabrics treated with lower DD 70 of chitosan showed better antimicrobial activity for all samples.
