Cover Factor:
Cover factor is a number that indicates the extent to which the area of a fabric is covered by one set of threads. For any woven fabric, there are two cover factors: a warp cover factor and a weft cover factor. It is depends on thread density and thread count. The higher the thread density is the higher the cover factor but the higher the thread count is the lower the cover factor.

From the Table and Figure we were seen that the highest warp cover factor is 38.2 of Boxy and the lowest warp cover factor is 21 of Plain. Also we were seen that the highest weft cover factor is 21.9 of Ottoman and the lowest weft cover factor is 11.4 of Plain. Further we were seen that the highest total cover factor is 31 of Boxy and the lowest cover factor is 23.9 of Plain. So all the results we have got regarding cover factor comply with the theory.
