Thermal absorptivity is an indicator of warm and cool feeling of textile materials. An equation based on thermal absorptivity of polyester in solid form, porosity of a fabric, and relative contact area of human skin and fabric surface has been developed to characterize thermal absorptivity of fabric. For verification of suggested model, 15 knitted rib fabrics were produced using 100% polyester yarn and having different surface profile. ALAMBETA semiautomatic non-destructive instrument has been used for measuring the effective thermal absorptivity of knitted rib fabric. It was found that the suggested simple theoretical model exhibits significant agreement with the measured thermal absorptivity values of knitted rib fabric, which endorsed the approach applied.

The aim of this study was to develop V-shape compression socks that should exert graduated lateral compression around the leg. For the development of socks, three types of yarns: main yarn (MY), plaiting yarn (PY) and inlaid yarn (IY) were used. Each yarn contained spandex yarn as the core. Machine adjustments were optimized to achieve the special V-shaped compression socks according to size of the wooden leg. Eighteen socks samples were developed and quantified for pressure exertion at ankle and calf portions using the MST MKIV, Salzmann pressure measuring device. Consequently, only two socks samples were accepted, which had the pressure exertion values of 21 mmHg and 23 mmHg with graduation percentage of 73% and 80%, respectively.

This study investigates the effect of material composition on moisture management properties. Fiber type has significant influence on the moisture management properties of knitted fabrics. In this article, single jerseys knitted fabric samples with different yarn compositions were prepared. Liquid moisture transportation properties including wetting time, absorption rate, spreading speed, one-way transportation capability, and OMMC were evaluated by Moisture Management Tester (MMT) and vertical wicking was evaluated using thermography system and image analysis. Knitted sample having fine cotton yarns with coolmax and micro denier multifilament polypropylene showed best liquid transportation properties. There is a strong co-relation between OMMC and accumulative oneway transport index with vertical wicking of knitted samples.
