Human-Made Fibres
Human-made fibres are created in factories using chemicals or natural materials.
They are divided into two types:
- Synthetic Fibres (fully man-made)
- Regenerated Fibres (partly natural, partly chemical).
Synthetic Fibres
| Type | Properties | Uses |
|---|---|---|
| Polyester | • Strong and durable | • Clothing: shirts, trousers, dresses |
| • Does not absorb moisture | • Household: bed linen, curtains, cushions | |
| • Easy to wash and quick drying | ||
| Nylon | • Strong and lightweight | • Clothing: jackets, leggings, tights |
| • Can lose shape if stretched | • Household: carpets, net curtains | |
| Acrylic | • Soft and warm | • Clothing: jumpers, blankets |
| • Mimics wool |
Regenerated Fibres
| Type | Properties | Uses |
|---|---|---|
| Viscose | • Drapes well and soft | • Clothing: dresses, shirts, jackets |
| • Absorbs moisture | • Household: cushions, upholstery | |
| Acetate | • Lightweight and weak when wet | • Linings of clothes, soft furnishings |
Care of Human-Made Fibres
Synthetic fibres:
-
Wash at low temperatures.
-
Avoid high heat when ironing – it can melt the fabric. Regenerated fibres:
-
Hand wash or machine wash on a gentle cycle.
-
Avoid high heat to prevent shrinking. 📌 Key Note: Human-made fibres are durable, easy to care for, and cheaper than natural fibres, but they are often non-biodegradable.
Quick Comparison: Natural vs Human-Made Fibres
| Feature | Natural Fibres | Human-Made Fibres |
|---|---|---|
| Source | Plants and animals | Factories (chemicals) |
| Properties | Breathable, soft, eco-friendly | Durable, quick drying, affordable |
| Care | Special care required | Easy to care for |
| Sustainability | Biodegradable and eco-friendly | Often non-biodegradable |
