"[9] Twisting fibres into yarn in the process called spinning can be dated back to the Upper Paleolithic,[10] and yarn spinning was one of the first processes to be industrialized. Further studies suggest that known allergens applied during textile processing are minimally present in wool garments today given current industry practices and are unlikely to lead to allergic reactions.[8].

Slub Effect means a yarn with thick and thin sections alternating regularly or irregularly. [6] In fact, contrary to popular belief, wool allergies are practically unknown. Textile measurements are taken at a standard temperature and humidity, because fibers can absorb moisture from the air. Synthetic fibers come in three basic forms: staple, tow, and filament. Another group of man-made fibres (and by far the larger group) is the synthetic fibres. d. The process of removing seed from cotton is called ginning. These short fibers are spun into longer filaments to make the yarn. Texturized yarns are made by a process of air texturizing filament yarns (sometimes referred to as taslanizing), which combines multiple filament yarns into a yarn with some of the characteristics of spun yarns. The cotton plants are grown in fields. Most yarns have a single uniform hue, but there is also a wide selection of variegated yarns: Yarn quantities for handcrafts are usually measured and sold by weight in ounces or grams.
