To improve the aesthetic appeal of pantyhose, the design and development of a new product and a wear experiment were carried out. The sheerness and visual impression of circular plain knitted fabrics made from novel color polyurethane yarn and single covered yarn with color polyurethane core yarn were examined. The results show that pantyhose samples made from polyurethane yarn have a less anisotropic property of light transmittance and that color polyurethane yarn is useful for improving the distribution of lightness difference between legs with and without the pantyhose on the lower leg part from knee to ankle. It is important to maintain a mean value of 15∼20 and a standard deviation of 3∼5 in the variation of lightness difference on the entire leg wearing pantyhose.

The paper reports the physical and mechanical properties of hand-woven carpets, which have been under static and dynamic forces. Two groups of wool fibres, from two parts of Iran, were prepared to spin pile yarn for the carpets. Each group of the fibres included both conventional and tanned wool. Then two yarn counts, N_m=2/4 and 2/6, were spun for two different knot densities. After weaving the carpets, they were put under static and dynamic forces and their thickness variations were measured and plotted against time (in case of static force) or number of impacts (in case of dynamic force). The resiliency of the carpets piles after eliminating the static and dynamic forces were measured and plotted against time, too. The results were compared to each other and analysed with respect to parameters such as the type and quality of the wool fibres as well as knot density of the carpet.
