An analysis on the moisture and thermal protective performance of 3-dimensional knitted spacer fabrics

Popis výsledku v původním jazyce

The physiological comfort is determined by the state of the organism during physical activity, and thermal comfort is determined by the feeling of warmth/coldness and damp/dryness, which depends on the air permeability and capability to absorb and evapourate sweat. Since Spacer fabrics consist of three layers of fabrics which have ability to complement and maximize the essential thermal clothing comfort for various applications. Nowadays lots of research works are carrying out on spacer fabrics for thermo-physiological comfort clothing, but still insufficient literatures are available on this area. Clothing comfort is also defined by the tactile sensations felt by a subject through the mechanical interactions between the body and the garment. In this work, Thermal and Moisture properties of warp knitted 3D spacer fabrics have been evaluated by varying the different spacer fabric parameters such as structure, areal density, thickness, type of raw materials etc. Air permeability and water vapour transmission of the fabrics were measured using the Textest FX-3300 air permeability tester and PERMETEST. Then thermal behavior of fabrics was evaluated by Alambeta instrument and overall moisture management capacity was evaluated by moisture management tester. Analysis of Variance (ANOVA) was performed using new statistical software named QC expert trylobite and Darwin in order to compare the influence of different fabric parameters on thermo-physiological behavior of samples. This study established that the raw materials, type of spacer yarn, density, thickness and tightness of surface layer have significant influence on thermal conductivity in spacer fabrics. The parameter which mainly influences the water vapour permeability of these fabrics is the properties of raw material i.e. the wetting and wicking properties of fibers. These findings are important requirements for the further designing of clothing for extreme environmental conditions.
