Spinning is a twisting technique to form yarn from fibers.The fiber intended is drawn out, twisted, and wound onto a bobbin.A few popular fibers that are spun into yarn other than cotton, which is the most popular, are viscose (the most common form of rayon), animal fibers such as wool, and synthetic polyester.

In textile spinning, yarn realisation (YR), or yarn recovery, is an operational parameter of yarn manufacturing. It is the percentage conversion of raw material to finished yarn. The rest of the waste fibers with less value are compared to the weight of the produced yarn from a given weight of raw material.
Textile manufacturing in the modern era is an evolved form of the art and craft industries. Until the 18th and 19th centuries, the textile industry was a household work. It became mechanised in the 18th and 19th centuries, and has continued to develop through science and technology since the twentieth century. [ 2 ]
The direct spinning process avoids the stage of solid polymer pellets. The polymer melt is produced from the raw materials, and then from the polymer finisher directly pumped to the spinning mill. Direct spinning is mainly applied during production of polyester fibers and filaments and is dedicated to high production capacity (>100 ton/day).
Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about 5000 B.C. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving to create cloth. The machine used for weaving is the loom.
Friction spinning: air is used to propel the sliver of fibres (1) to a carding drum (2) where they drop (3) between two perforated drums (5) that integrate and twist the yarn. Friction spinning or DREF spinning is a textile technology that is suitable for spinning coarse counts of yarns and technical core-wrapped yarns.
Cotton-spinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. [1] Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cotton-spinning machinery was developed to bring mass production to the cotton industry.
Ring spinning is a continuous process, unlike mule spinning which uses an intermittent action. In ring spinning, the roving is first attenuated by using drawing rollers, then spun and wound around a rotating spindle which in its turn is contained within an independently rotating ring flyer. Traditionally ring frames could only be used for the ...
