Spinning: yesterday and today

Spinning, a practice that once was done by hand using the spindle or spinning wheel, is a process that prepares textile fibers by mixing and refining them, which is used for untangling them and to arrange them on a belt and then on a wick. From the industrial revolution onward, the use of increasingly specialized machinery has made it possible to produce yarns with an appreciable degree of tenacity and finesse as well as a uniform thickness and twist.

The characteristics of the twist

Twisting, which can be performed to the right (S-shaped twisting) or to the left (Z-twisting), helps to give the yarn resistance and prevent fraying. It can be expressed in two ways, by measuring the length per unit of weight or by weight per unit of length, which is what characterizes the yarn's fineness.

Decorative effects obtained from yarn

There are also many decorative effects that can be obtained on a yarn by mixing fibers of different color or type (melange effect) or by changing the thread section (flame effect) or by adding fiber particles, often of contrasting color (bottleneck effect).
