Objective and subjective evaluations of quilted mattress ticking fabrics for their thermal comfort performances

Abstract

PurposeSleep quality, a crucial parameter for health and life performance, is affected by mattress components; particularly mechanical and thermal comfort management ability of the upper layers. The aim of this study is to investigate effects of quilted mattress ticking fabric material (polyester, polypropylene, viscose, lyocell and their blends) on thermal comfort of the bedding system by objective and subjective measurements.Design/methodology/approachThe permeability (air and water vapour), heat transfer, water absorption, transfer and drying behaviours of knitted quilted fabrics which influence the thermal comfort of the bedding system were investigated. Subjective coolness and dampness evaluations were gathered by forearm and hand-palm tests to provide more realistic discussion in light of fabric characteristics.FindingsAccording to the results, polypropylene can be suggested for winter use with its higher air and water vapour permeabilities, lower thermal absorption and conductivities and warmer evaluation results. Lyocell can be suggested for summer use with also high permeabilities, higher thermal absorption and conductivities and cooler evaluation results. Polyester and viscose may also be considered for winter and summer in turn as a result of thermal feelings they create.Originality/valueIn addition to fabric thermal, permeability, liquid absorption and transfer properties, this study also includes subjective coolness and dampness evaluations which can provide realistic results regarding the coolness-to-touch and liquid transfer performances of mattress ticking fabrics. The relationships among objective and subjective data were investigated and the proposed subjective evaluation techniques can be used for different products.
