Moisture Vapor Transport Behavior of Polyester Knit Fabrics

130

Double face fabrics are used to ensure better clothing comfort in sports and active wears. High moisture transfer properties of these fabrics affect their comfort properties and make them more functional. In this study, in order to investigate the moisture management properties of the double face fabrics, a special knitting structure, which has different or same yarn combinations in the face and back sides, was used. The selected yarns were cotton—cotton, cotton—polypropylene, polypropylene—cotton and polypropylene—polypropylene for face and back sides respectively. Moisture management properties and the changes of the thermal absorptivity values, which determine the warm-cool feeling, of the produced fabrics were determined and statistically analyzed. All measurements were done both in dry and wet conditions. The results indicate that, the polypropylene (inner)-cotton (outer) fabric has better moisture management property, provides high levels of comfort and can be preferred for summer, active and sports wear.

“…They attributed these differences to the fact that hydrophilic fibers retained water molecules and could even swell to reduce the porosity of the fabrics. Prahsarn et al [6] reported that water vapor transmission rate was strongly correlated with fabric thickness, and fiber-related factors such as cross-sectional shape and moisture absorbing properties did not play a significant role. Also, in the literature it was shown that water vapor permeability was in close relation to air permeability [28].…”

Socks need to perform better in comfort properties than other garments, as less air circulation occurs in socks in shoes than in garments on other parts of the body. In this paper, we studied the comfort properties of socks made from new fibers, such as modal, micro modal, bamboo, soybean, and chitosan. In order to compare their properties with conventional fibers such as cotton and viscose, these fibers were also included in the study. Water vapor transfer, air permeability, wicking, wetting and heat transfer — properties which are related to comfort — were evaluated. In order to conduct thermal conductivity measurements, a special experimental setup was designed according to the hot plate method (ISO 8302). The results suggested that the fiber type, together with regain and fabric properties such as thickness, appears to affect some comfort-related properties of the fabrics. It is suggested that for certain end uses, various combinations of fiber blends can be used.

“…Absorption of sweat and its transportation through and across the fabric are related to clothing comfort properties of the fabrics. [6][7][8][9][10][11] Drying time is another important aspect while determining a comfort level. 12 There is a general agreement that fabric thickness, density and porosity are critical factors to determine comfort perceptions.…”

In this study, it was aimed to investigate the relationship between different knitted structures and some thermophysiological comfort parameters. Wetting, wicking and drying properties of single jersey, 1 Â 1 rib, 2 Â 2 rib and interlock knitted fabrics made out of acrylic yarns were studied and experimental wicking height, wicking weight, transfer wicking ratio, contact angle and WER (water evaporation rate) values were measured. Samples were produced in two different tightness values to obtain slack and tight fabrics for all structures. Some comfort-related parameters were correlated with structural parameters of fabrics such as fabric tightness factor, thickness, porosity, loop length and pore size etc. The statistical analysis results indicate that the effect of the knitted structure is significant for wicking height, wicking weight, contact angle values, transfer wicking ratios and WER values. Wicking height increases depending on knitted structures namely, single jersey, 1 Â 1 rib, interlock and 2 Â 2 rib, respectively. Slack fabrics have longer loop lengths with higher porosity values and higher pore sizes for all knitted structures. Slack structures of 2 Â 2 rib, 1 Â 1 rib, interlock and single jersey knits have higher transfer wicking ratios when compared with their tight structures. WER is inversely related with fabric thickness. It decreased with an increase of thickness due to increase of compactness and decrease of air space. All tight knitted structures have higher contact angles than their slack forms due to compactness of the surface.
