Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. [11] These strands of yarn are twisted together (plied) in the opposite direction to make a thicker yarn. These short fibers are spun into longer filaments to make the yarn. Long continuous strands may only require additional twisting to make them into yarns. Spinning is a process of making fibres. Common sizes include 25 g, 50 g, and 100 g skeins. Combining synthetic fibres (which can have high strength, lustre, and fire retardant qualities) with natural fibres (which have good water absorbency and skin comforting qualities) is very common. Labels on yarn for handicrafts often include information on gauge, known in the UK as tension, which is a measurement of how many stitches and rows are produced per inch or per cm on a specified size of knitting needle or crochet hook. Textiles made using pineapple fibre get softer with each passing generation, and transform into a vintage beige colour, making this a true heirloom material.

Filament is fibre of great length, including the natural fibre silk and the synthetic fibres. These thin strands of cotton which make up the yarn are called cotton fibres. Staple is cut fibers, generally sold in lengths up to 120mm. Strength, extension, fineness, length and surface properties are some of the primary attributes of fibres which, using different types or blends of fibres, create a wide spectrum of useful and desirable physical and mechanical properties in the yarn and fabric produced. d) The process of removing seed from cotton is called ginning. Jute is obtained from the of plant. Fibres from a mass of cotton wool are drawn out and twisted. Filament yarns generally require less twist than staple. By Simone Preuss. [14] Some of the names for the various weights of yarn from finest to thickest are called lace, fingering, sport, double-knit (or DK), worsted, aran (or heavy worsted), bulky, and super-bulky.
