The geometric structure of color.

Using the Geometric Model to Explain the Longitudinal and Cross–Sectional Reflection Behaviors of Acrylic yarns

In the present work the reflection behavior and the color appearance of acrylic yarns, as pile yarns used in carpet and pilled fabrics, are considered along their lengths as well as their cross- sections. Differences between longitudinal and cross-sectional reflection behaviors of yarns are measured in different yarn densities and hues and explained by the geometric model. The results of experi...

A Comparative Study on an Ilkhanid Textile and the Seljuk Pottery

Pottery and textile weaving were two art media during the Seljuk and Ilkhanid periods, which one or sometimes both were considered important according to circumstances. Numerous studies have been carried out on pottery and weaving in the Seljuk period, and in some cases the evidence left over from that time has been reviewed in a comparative method to determine to some extent how these works we...
