Spun yarn is produced by placing a series of individual fibers or filaments together to form a continuous assembly of overlapping fibers, usually bound together by the twist.
Characteristics of textile spun yarn
- Composed of short-staple fibers of a definite length
- Made from natural cotton, flax or wool staple fibers
- Made from natural or man-made filaments which are chopped or cut into short lengths and referred to as filament staple yarns
- Individual fiber length varies
- Bigger and wider in diameter than filament fiber yarns
- Fuzzy appearance and feel, fiber ends protrude from yarn
- An uneven number of fibers throughout
- Range from soft, loose construction to hard finished, fine twist yarns
- Thick and thin areas highly twisted
- Fall apart when untwisted
- Dull or flat in appearance
- Rough to touch
- Natural textural appearance and feel
- Bulkier to the feel
- Provide good covering power
- Snagging depends on fabrics structure
- Pilling depends on fiber content
Spun Yarn Overview
1. Yarns made from short length fibers and the fabrics are like cotton and wool.
2. Short fibers twisted into continuous strand, has protruding ends
1. Dull, fuzzy look
2. Lint
3. Subject to pilling
4. Soil readily
5. Warm (not slippery)
6. Loft and bulk depend on size and twist
7. Do not snag readily
8. Stretch depends on amount of twist.
3. Are absorbent
4. Size often expressed in yarn number
5. Various amount of twist used
6. Most complex manufacturing process
