Another group of man-made fibres (and by far the larger group) is the synthetic fibres. 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]. The twist direction of yarn can affect the final properties of the fabric, and combined use of the two twist directions can nullify skewing in knitted fabric. Woollen refers to a yarn produced from carded, non-parallel fibre, while worsted refers to a finer yarn spun from longer fibers which have been combed to be parallel.

Two important things in spinning of yarn that will later on affect the fineness and strength of the fabric woven. In knitting, yarns are interlooped. 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. This process brings all the fibres together to from a yarn. In this process, fibres from a mass of cotton are drawn out and twisted. Thicker monofilaments are typically used for industrial purposes rather than fabric production or decoration. A fairly high degree of twist produces strong yarn; low twist produces softer, more lustrous yarn; and tight twist produces crepe yarns.
