The moisture sorption isotherm was determined primarily at 30•Ž for fifteen kinds of wool and hair fibers from sheep, goat, camel, and rabbit families. The isotherm was analyzed in terms of Brunauer, Emmett and Teller

SUMMARYIn order to weave fabric based on a yarndyed fabric sample, the information on the thread arrangement of the fabric must be obtained. In this paper, we will discuss a method for automatically extracting the design elements of yarndyed fabric that correspond to thread placement information with the objective of automating a part of the fabric design process of yamdyed fabrics. In yamdyed fabrics, the pattern on the fabric's surface is forrned by the placement of different colored warp and weft threads. Consequently, the features of the warp and weft threads are always continuous in the warp and weft directions. As a result, we show that the bandpass image obtained by filtering the fabric's surface in the spatial frequency domain with a rectangular filter restricted to the warp direction or weft direction extracts information related to the thread placement in that direction. In addition, a simple clustering preprocessing method that detects the brightness is proposed. Then it is verified that the design elements of yarndyed fabric can be extracted based on clustering where the color difference in the bandpass image is the distance. When extracting yamdyed fabric elements, these methods are not concerned with individual regions of the pattern on the fabric's surface or features of each thread but are only concerned with the placement of the colored threads that define the design elements of the yarndyed fabric. They are also provided with an efficiency not available in earlier methods.
