“…In the field of textiles, there are several studies on the liquid moisture transfer in cloth [7,8,9]. Their purpose, however, was to compare the characteristics of moisture uptake between different kinds of cloth and those studies are not sufficient for evaluating the thermal effects of the moisture absorption/adsorption to and evaporation from the clothing.…”

AbstractIn order to design an efficient air-conditioning system, the specifics of the transient thermal and physiological responses of a human body to the hygrothermal environment should be taken into account. This response will strongly depend on the behavior of heat and moisture transport, and moisture accumulation in the clothing, especially when sweat exists in and around the clothing. As a basic information on this problem, a model of the moisture transfer in cloth is necessary.In this paper, a model of the liquid moisture movement in clothing under gravity is developed and applied, based on a diffusion model. Firstly, the moisture diffusivity is determined from the investigation of the moisture absorption process in the horizontal direction where gravity has no influence on the moisture movement. Secondly with the use of the moisture diffusivity thus determined, a moisture absorption process in the upward direction against gravity is investigated. The validity of the parameter related to the gravity effect is examined by comparing the results of numerical calculations with the experimental results obtained from the gamma-ray method. Since the two agree generally well, the parameters viz. liquid moisture diffusivity and sorption isotherm derived here for a sample of broadcloth are considered reliable.

“…The effective forces during the capillary flow occurring in the vertical direction were capillary forces that affected upwarp and gravity forces that affected down. Accordingly, the pressure difference (ΔP) during the capillary flow at a straight capillary tube was defined by Equation (5), described by the Laplace equation as follows [16]:…”

Several studies were oriented to the investigation of the porous structure of woven fabrics [9][10][11]. Through several studies have treated the pores as cylinders with a permanent cross-section over all its length, the pore size and shape are completely uneven. The same is valid for the pore distribution in the woven fabric [12]. AbstractDue to the complexity of fabric structure, modeling of pore structure and predicting the pore parameters are difficult. This paper presents a novel approach to determine textile pore size, porosity and pore size distribution by the application of the image analysis techniques. In this study, it has been attempted to establish a theoretical model for both the pore size and porosity of woven fabrics. For this purpose, a theoretical model of porous systems based on Poiseuille's law was used to predict the pore size of woven fabrics. Also a theoretical model was created to predict the porosity of a woven fabric depending on the geometrical parameters. The two characteristics of pore opening size and porosity were determined from image analysis and were compared to the results from laboratory tests. The validity of which was confirmed by experimental results using cotton plain woven fabrics produced from different yarn linear density and tightness. A new and accurate method of image analysis for pore size distribution (PSD) determination of woven fabrics is presented in this paper. The tested fabric sample could be ranked in a decrease order successfully.

“…The effect of plasma treatment on the spontaneous water uptake amount of fabrics was determined by the demand wettability test (Miller & Tyomkin, 1984). The demand wettability test is a sensitive gravimetric method which is capable of measuring the rate and the total amount of liquid uptake in the direction perpendicular to the plane of a fabric.…”

: The objective of this study is to give PP(polypropylene) fabric a good affinity for water. Oxygen plasma was treated to PP fabrics in a commercial glow discharge reactor with different RF power, discharge pressure, and reaction time. The PP fiber surfaces were characterized by the measurement of contact angle and ESCA. A JEOL scanning electron microscope was used to observe the surface morphology of fibers. The spontaneous water uptake amount of PP fabrics was determined by the demand wettability test. To determine the effect of aging on the surface properties of O 2 plasma treated PP, all the above measurements of the samples were carried out after 1, 7, 30, 60, and 150 days. The results are as follows. The PP fiber surfaces treated by O 2 plasma treatment have a chemical composition that consisted of various oxygen containing polar groups. Consequently, the contact angles of the treated PP fibers decreased, which improved the water uptake rate of PP fabrics. Surface roughness of the treated PP affected the fabric wettabiity as well. Wettability of the treated PP decreased and leveled off with aging. The O 2 plasma treatment is a simple and effective method to increase the water uptake rate of PP fabrics.
