Yarn is selected for different textiles based on the characteristics of the yarn fibres, such as warmth (wool), light weight (cotton or rayon), durability (nylon is added to sock yarn, for example), or softness (cashmere, alpaca). Yarn is composed of twisted strands of fiber, which are known as plies when grouped together. [19]
Diagram showing S and Z twist. There are two common ways to ply a balanced yarn: regular and chain plying. Both methods involve the manipulation of "singles"—unplied strands on their own—into multiple-ply yarns by applying twist in the opposite direction than how the single was spun. For example, if in spinning the single the wheel was spinning clockwise (called a "Z" twist, as on any ...
Preferably, Z-twisted yarns should have a firm close twist to avoid the yarn from untwisting completely. Most suited are high Z-twisted and low S-plied yarns. [17] The technique always refers to knitting with two strands of yarn, even when knitting a monochrome fabric. The strands of yarn can come from one or two balls of yarn.
In a sewing thread, the treads are doubled in two phases. Two or three strands are twisted together then three of these threads are twisted together, to form a six or nine cord. [9] The spun yarn is wound onto a bobbin using a doubling winding machine, and two or more of these bobbins are placed on doubling frame (doubling winding machine). The ...
The Spinner by William-Adolphe Bouguereau shows a woman hand-spinning using a drop spindle.Fibers to be spun are bound to a distaff held in her left hand.. Spinning is an ancient textile art in which plant, animal or synthetic fibres are drawn out and twisted together to form yarn.
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.

The industrial revolution in the 18th century led to mass production of yarn and cloth, which led to the growth of the woven fabric part of the textile industry. [101] Warp and weft: Knitting: Knitting involves interlacing loops of yarn, which are formed either on a knitting needle, needle, or on a crochet hook, together in a line. The ...
Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural or synthetic fibres. [1] [2] [3] Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be ...
