TWILL WEAVE

Weaving has  a numbers of weaves in which there  are mainly three basic weaves. These basic weaves are Plain, Twill and Satin/sateen weave. One of its important weave is Twill weave. Twill weave is a type of textile Weave  with a pattern of diagonal parallel ribs which is in contrast with a satin and plain weave as it has more floats then these two weaves.

During the construction of twill weave, weft thread is passed over one or more warp threads and then under two or more warp threads and so on, with a "step" or offset between rows to create the characteristic diagonal pattern which creates small floats in the fabric to give it a new look other than plain fabric. Straight draft is usually used in twill weave.It requires three or more heald shaft for producing the design.

In the structure of  twill weave, each weft or filling yarn floats across the warp yarns which causes an interlacement in right or left direction, forming a distinct diagonal line. A float is the portion of a yarn that crosses over two or more yarns from the opposite direction. By using colourful and different counts of threads, even a simple twill weave can give a variety of appearances to a plain fabric.

The  construction of twill weave is done in fraction of 2/1 and this fraction shows which number of harnesses is to be lifted up or lowered. For instance, in the given fraction, the numerator indicates the number of harnesses that are raised (and, thus, threads crossed – in this example, two), and the denominator indicates the number of harnesses that are lowered when a filling yarn is inserted.

Visually, Twill weave lokks same from both side but technically it has two sides. Technically, Twill weave has one face side and second back side. The technical face side of a twill weave fabric is the side with the most pronounced wale; it is usually more durable, more attractive, most often used as the fashion side of the fabric, and the side visible during weaving. Depending on the directions of twill, twills are classified into Z Twill and S Twill.

Using twill weave,  Sheer  fabrics are made with a twill weave. Because a twill surface has interesting texture and design.

Twill weave is mostly used in every category of  textile material whether it is home furnishing or dress material , It is a perfect weave for every fabric. It gives a prettier look on simple furnishings used in day to day life whic also have a good durability.
