3. Characteristics
| Feature | Yarn | Thread |
|---|---|---|
| Texture | Usually thicker and softer | Finer, smoother, stronger |
| Twist | Moderate twist for flexibility | High twist for strength and durability |
| Appearance | Comes in many textures (fuzzy, bulky, smooth) | Smooth and even, suitable for sewing |
| Stretch | May have elasticity depending on fiber type | Less stretch, more stability for stitching |
| Ends | Often frays easily | Specially treated to resist fraying |
4. Properties
Yarn:
- Softness – comfortable for making clothes and accessories.
- Bulkiness – suitable for creating warm, thick fabrics.
- Elasticity – especially if made from synthetic or blended fibers.
- Absorbency – cotton yarns absorb moisture well.
- Versatility – comes in many thicknesses and textures.
Thread:
- High strength – needed for stitching and durability.
- Smooth surface – helps it move easily through fabric without damage.
- Heat resistance – especially in threads used for industrial sewing.
- Low lint – minimizes dust and fuzz while sewing.
5. Examples
Yarn:
- Cotton yarn – used to knit dishcloths or baby clothes.
- Wool yarn – used for making sweaters or scarves.
- Acrylic yarn – used in crafts and cheap garments.
