What is Yarn?
Yarn is a basic unit in most textile construction. The yarn is made largely by a combination of repeated twists and stretching of a bundle of fibres into a continuous line or by twisting a continuous filament (p9, The Yarn Book).
Composition of the threads impacts the texture and appearance of fabric with the amount of twist in the fibres determining balance and drape. The number of fibres and plies help determine thickness and weight of the fabric.
There are two types of spinning used in yarn production extrusion spinning (manufactured fibres and filament silk) and staple spinning (natural fibres and silk waste).
The purpose of twist is to bind the fibres into a thread.
Single threads are almost always twisted in one direction and the convention is that fibres are rotated clockwise front he point of tension. It adds strength by binding the threads together.
Earliest evidence of yarn comes from a fragment unearthed at Catal Huyuk in Turkey and dated 8000 years old (p.17, The Yarn Book).
Types of Fibres
Proteinic Fibres (Animal Fibres)
- Alpaca and Llama
- Vicuna(high Andes)
- Angora Rabbit
- Possum (in New Zealand where introduced pest)
- Other plants
- Rayon and Viscose
- Acetate and tri-acetate
- Aramid fibres
- Bi-compent fibres
Yarn in Fabric
Almost all fabric except felt are dependent on the yarn used to make them. Yarn impacts the behaviour and performance of the fabric. Fibre, twist, radius and elasticity and surface lustre, colour and spinning design make the yarn suitable for the particular sort of fabric. Designs sometimes use yarns as a decorative feature of the fabric or for the surface for a printed design or contrasting textures or weights.
Textiles in which Yarn plays an important role in the look and behaviour of the cloth include brocade, calico, chambray, chenille, chiffon, damask, denim, dupion, hessian, lawn, muslin, organdie, poplin, satin, sateen, spandex,taffeta, tweeds and velvet.
There is a new generation of yarns being shown at international design fairs and renewed interest in organic yarns. A huge global industry is driven by scientific innovation from science research organisations (CSIRO in Australia), Universities and in-house research and development.
A specialised yarn show is Premiere Vision (formerly Expofil) in Paris and also the Pitti Immagine Filati show in Florence.
New Fibres include:
- Aquacel – from seaweed
- Dupont – new nylon threads
- Bulgetti Filati – stretch steel
- Plastic – recycled
- Lenpur – vegetable cashmere
- Sensory textiles
