General Properties of Yarn

Various types of yarn properties according to the yarn classification have been summarised in the following table:

Yarn Types and Their Properties
Sl	Yarn Types	General Yarn Properties
1	Staple yarns - Combed cotton - Carded cotton - Synthetic and blends - Worsted - Woollen	Good hand, cover, comfort and textured appearance. Average strength and uniformity.
2	Continuous filament yarns - Natural - Man-made or synthetic	High strength, uniformity and possibility for very fine yarns. Fair hand and poor covering power.
3	Novelty Yarns - Fancy - Metallic	Decorative features and characteristics.
4	Industrial Yarns - Tyre cord - Rubber or elastic core - Multiply coated	Functional; designed and produced to satisfy a specific set of requirements.
5	High-bulk Yarns - Staple - Continuous filament (Taslan)	Great covering power with less weight, high loftiness or fullness.
6	Stretch Yarns - Twist-heat set-untwist - Crimp heat-set - Stress under tension - Knit-deknit - Gear crimp	High stretchability and cling without high pressure, good handle and covering power.

Spun yarn can be classified as either short-staple spinning or long-staple spinning. Staple fibre has a length of between 10 and 500 mm. Short staple fibre has a maximum length of 60 mm (cotton fibre is a short-staple at about 25–45 mm). Long-staple fibre has a length of more than 60 mm (wool fibre is a long-staple at about 60–150 mm).
