Types of yarns

Fabrics are enhanced by these yarns as they make them more comfortable to wear. These yarns are used in both woven and knitted fabrics for a wide range of clothing. Strong sewing threads are often made by this method. The outer covering prevents the needle over heating in high volume sewing production. Elastane filaments are covered with another yarn. Knitting and weaving is difficult with elastic yarns. These are multi component yarns; the core at the centre covered with either natural or manmade yarns. Often chosen for their appearance, but also for their functional characteristics such as strength and elasticity. Special spinning processes give rise to irregularities adding to the texture – slub, loop, chenille or bouclé. Fibres of different colours are created during spinning or by plying 2 or more coloured yarns. Matt and bright fibres such as Lurex can be mixed for different effects. Often used to create interest and improve the appearance of woven and knitted materials. Often made by blending staple fibres with different shrinkage values to make thicker and softer yarns. Acrylic and cotton are a common combination – the heat process will bulk up the acrylic whilst fluffing up the cotton. Acrylic and cotton combination gives an inexpensive yarn that is lightweight, easy-care, soft and warm, suitable for knitwear. A thermoplastic synthetic filament yarn such as polyester or nylon is finished using a heat process which adds crimps, coils and loops along the length. This process adds thickness to make yarns warmer, more elastic, absorbent and gives a softer handle. Suitable for tights, swimwear, underwear, outerwear, fleece jackets and carpets
