The instrument is unique in that it can not only measure the initial water absorption of the fabric in the transplanar direction, but also the rate of evaporation from the fabric surface after fully saturated with water, with the temperatures of water controlled at different levels simulating the end use conditions of the fabric. Compared with existing instruments for the water transport behaviour of fabrics or papers, the new instrument has a unique mechanism to control the water level underneath the fabric sample at a constant level (i.e. the water level is not reduced with the water transport into or through the fabric sample); as a result, the measurements are not affected by the changes of hydrostatic water pressure during testing. Repeated tests on various fabric samples showed that the measurements from the instrument are accurate, sensitive and reproducible.

The ability of clothing materials to transport moisture, liquid water and air is critical to wear... more The ability of clothing materials to transport moisture, liquid water and air is critical to wear comfort, especially in conditions where sweating is the key mechanism for cooling the human body. As sweating proceeds, the humidity in the clothing microclimate and skin wetness may rise to an uncomfortable high value. The influence of clothing materials on such build-up of sweats at the skin surface depends on their ability to transfer liquid sweat and moisture. A fabric that is perceived as comfortable should facilitate fast transmission of liquid sweat and moisture during the period when the body sweats actively.

Synthesis and properties of the new difunctional methacrylate monomer 2-hydroxy-3-methacryloyloxy... more Synthesis and properties of the new difunctional methacrylate monomer 2-hydroxy-3-methacryloyloxypropoxybenzene are presented. This monomer was applied for the synthesis of porous microspheres. It was copolymerized with trimethylolpropane trimethacrylate in the presence of two pairs of pore-forming diluents dodecane and toluene, and n-decanol and toluene. Influence of diluents composition on their porous structures was studied. Thermal resistance and tendency to swell in different organic diluents for a chosen sample were also determined.
