Abstract
This research work presents a laboratorial method based on a scientific basis and, in the same time, easy, simple, and not costly with respect to capital, labour, or raw materials, to predict the geometrical properties and constructional details of the fabric before it is woven. Yarn diameter, yam count, and weave structure each for warp and Weft are used to predict maximum density of yarns in the fabric i.e. yam weavability. Limit, maximum yarn crimp ratio, maximum yarn cover ratio, maximum fabric cover ratio, fabric thickness, maximum fabric weight per square meter, and maximum fabric volumetric density. By adding yarn density in the fabric required to be woven to the previously mentioned input data, the relative weaving density (the ratio between actual yarn density and maximum yam density), yam crimp ratio, yam cover ratio, fabric cover ratio, fabric thickness, fabric weight per square meter, and fabric volumetric density can also be predicted.
This methodology is suggested to be used instead of many instruments used in testing fabrics such as fabric thickness meter, yarn diameter ordinary meter, and yam crimp tester and helps reduce yarn waste as the amount of consumed yam can be accurately calculated. It helps also reduce costs of weaving by choosing the suitable Weaving machine according to relative weaving density of yarns, and costs of testing yarns and fabrics.
