Manufacture On the loom. . This is the most made weave in the world. There are no distinct designs. Properties It is easily produced.Appearance It has a flat appearance. The various color and weave effects that can be produced will be dealt with in another blog. However these may be produced if yarns have contrasting colours or thicknesses. It is relatively inexpensive. warp and weft are present in equal amounts. Square plain weaves In such weaves. These are used as surgical dressings. sheeting fabrics. fabrics for shoes and tents. dairy cloths. warp cover factor is equal to the weft cover factor. .Variations of Plain weave 1. canvas for transport covers and fabric for use as ribbons in type writers or computers. muslin dress fabrics. parachute fabrics. handkerchief fabrics. or in other words. 14% x 93% giving a weight of 130g/m2 and a cover factor of 20. 16 tex x 16 tex. the warp crimp is also high in these fabrics.
