Woven Fabric Design & Structure

The fabric is designed for a particular end use and should posses certain property such as: strength, flexibility, porosity, wears resistance, fineness and so on. This property is determined by the structure of the fabric, which is characterized by fabric setting, linear density, the fabric cover, crimp percentage, mass per unit area of the fabric and so on. The main characteristic of fabric is the density of the yarns or yarn spacing. But sometimes the yarn diameter is also taken into consideration. It is known that the fabric with the same thread density may have different spacing between the threads because of the difference of the diameter. Also, fabric with different densities of yarn may have the same space between the yarn when smaller densities are combined with greater diameter. Therefore, the relative closeness of yarns depends on the density of the thread and their diameter. In this book fabric weight calculations are used from the design point of view as they are important in determining the rate at which yarn will be consumed at the loom as well as the efficiency of the weaving.
