Multifunctional Performance of Spacer Knitted Fabrics

Popis výsledku v původním jazyce

This study also determines the influence of different structural characteristics of knitted a spacer fabric on the compressive behavior and energy absorption capability. The potential compression mechanism of the fabric was identified with support of the compression stress-strain curve, work done and efficiency at different compression stages. Third order polynomial regression model was used to establish the elastic deformation properties used to obtain the compression results. Spacer textile fabrics have superior thermal and acoustic characteristics compared to conventional woven/knitted structures, foams or nonwovens due to their wonderful 3D sandwich pattern and porous nature. Hence this research work also investigates the influence of different structural parameters of spacer fabrics e.g. areal density, porosity, thickness, stitch density etc. on thermo-physiological and acoustic performance. The sound absorption coefficient (SAC) was evaluated using two microphone impedance tube. Moreover, tortuosity of the spacer fabrics was calculated analytically and compared with experimental results. This study also discusses the influence of material parameters and structural characteristics on acoustic properties of 3D spacer knitted fabrics.
