TEXTILE
The fabric weave or design is the manner in which the warp and weft yarns are interlaced with one to another to produce a fabric.
Twist is the spiral arrangement of the fibers around the axis of the yarn. The twist binds the fibers together and also contributes to the strength of the yarn. The amount of twist inserted in a yarn defines the appearance and the strength of the yarn.
Different types of twist:-
Drafting
Drafting, in yarn manufacture, process of attenuating the loose assemblage of fibers called sliver (q.v.) by passing it through a series of rollers, thus straightening the individual fibers and making them more parallel. Each pair of rollers spins faster than the previous one.
Plain Weave:-
Plain weave is the most basic of three fundamental types of textile weaves. It is strong and hard-wearing, and is used for fashion and furnishing fabrics.
Twill Weave:-
Twill is a type of textile weave with a pattern of diagonal parallel ribs. This is done by passing the weft thread over one or more warp threads then under two or more warp threads and so on, with a "step," or offset, between rows to create the characteristic diagonal pattern.
Satin Weave:-
Satin is a weave that typically has a glossy surface and a dull back, one of three fundamental types of textile weaves along with plain weave and twill. The satin weave is characterized by four or more fill or weft yarns floating over a warp yarn, four warp yarns floating over a single weft yarn.
