Comfort is one of the most important aspects of clothing. Thermal comfort is related to fabric’s ability to maintain skin temperature and allow transfer of perspiration produced from the body. Properties like thermal resistance, air permeability, water vapor permeability, and liquid water permeability are suggested as critical for thermal comfort of clothed body. In this study the fabrics developed from the EliTe compact yarns are compared with the fabrics made from normal yarns. The thickness of the fabrics made from EliTe® compact yarns is also slightly less than the fabrics made from normal yarns. Fabrics made from EliTe® compact yarns have shown greater air permeability as compared to the fabrics made from normal yarns. It is observed that, thermal resistivity values of the fabrics developed from EliTe® compact yarns are lower than the fabrics made from normal yarns indicating they are cooler fabrics compared to normal fabrics. Fabrics developed from the EliTe® compact yarns have shown slightly higher values of MVTR (moisture vapor transmission rate) as compared to the fabrics made from the normal yarns. The wicking characteristic of fabrics developed from EliTe® compact yarns was slightly higher than the fabrics developed from normal yarns. 相似文献

A study of comfort performance in cotton and polyester blended fabrics. I. Vertical wicking behavior
Vertical wicking model was developed based on Darcy’s law. In the model, permeability coefficient, capillary pressure and
fabric thickness were used as the key parameters to describe wicking behavior. For the simulation and test, fiber type and
fabric structure were chosen as variables. In a highly porous knit fabric, gravitational effect during the wicking process
was significant. The higher the capillary pressure was, the higher was the wicking rise. Surface wetting tension, i.e., the
specific fluid affinity of material, was newly defined to characterize different capillary pressures in various types of fabric
structures. The model, the methodology and the results could provide an insight into fabric design to produce fabric with
an optimum wicking performance. 相似文献

The application of a degassing system to mercerization process was investigated. It was found that the physical properties
of cotton fabrics mercerized in the degassed NaOH solution were superior to those mercerized in NaOH solution. The degree
of penetration of the degassed water was examined by measuring wicking height. The wicking height in the degassed water without
the wetting agent is higher than that of the saturated water with 0.1 % of wetting agent. 相似文献

In this paper, the capillary rise method was applied to evaluate the wicking property of polyester filament yarns. Effects
of twist, monofil cross sectional shape and texturing on the wicking height were discussed in details. The results indicated
that with the increase of twist level, the wicking height ascends until reaching the maximum height, and then descends. It
is also observed that under the same twist level, the wicking height of the five-leaf low-stretch yarn is the largest among
all those three kinds of yarns, and then is that of the conventional low-stretch yarn. The wicking height of the parallel-drawn
yarn is the smallest. 相似文献
