Twill Weaves – There are so many weaves in textile Twill weave is one of them a type of textile weaves, with a pattern of diagonal parallel ribs. It can be identified by looking at the presence of pronounced diagonal lines that run along the width of the fabric. It has higher resistance to tearing than a plain weave because it has few yarn interlacing per area, therefore a greater degree of internal mobility. In addition, two yarns bear the load when the fabric is torn.
In all weaves Twill weaves are the weave that find a wide range of application. They can be constructed in types of many ways. Main feature of these weaves that make difference from other types is the presence of pronounced diagonal lines that run along the width of the fabric.
The basic characteristics of twill weaves
They form diagonal lines from one selvedge to another.
More ends per unit area and picks per unit area than plain cloth.
Less binding points than plain cloth
Better cover than plain weave
More cloth thickness and mass per unit area.
The twill weaves are produced in a wide variety of forms. They are however classified broadly into important categories, namely
Ordinary or continuous twills
Zig zag , pointed or wavy twills
Rearranged twills such as satin/sateen weaves and corkscrew weaves
Combination twills
Broken twills
Figured and other related twill weaves
The types of twills
Weft face twills
Warp and weft face twills
Warp Faced Twills
In these types of twills the warp thread floats over all the picks in a repeat except one pick. The minimum repeat size required is 3. Examples of warp faced twills are 2/1, 3/1, 4/1, 5/1 etc.
These twills are the reverse of the previous ones. In these weaves the weft thread floats over the warp on all picks in a repeat except one. Examples of weft faced twills are 1/2, 1/3, 1/4, 1/5 etc.
