Question: Which of the following is not an animal fibre?
A Silk
B Wool
C Polyester
D Pashmina
Answer: polyester
| Characteristic | Animal Fiber | Synthetic Fiber |
| Source | · Derived from coats or fur of animals. | · Produced from chemicals and polymers.
· These are typically petroleum-based. |
| Nature | · Natural fibers sourced from animals. | · Man-made fibers produced through chemical processes. |
| Examples
|
· Pashmina
· Wool · Silk · Cashmere · Mohair · Alpaca |
· Polyester
· Nylon · Acrylic · Polypropylene
|
| Composition | · Natural proteins or keratin | · Polyethylene terephthalate (PET) for polyester
· polyamide for nylon |
| Texture | · Often soft, warm and comfortable | · Some may have the feel of natural fibers |
| Strength and Durability | · Wool is known for its strength and elasticity.
· Silk is strong but less resilient. |
· Some are exceptionally strong and durable |
| Moisture Absorption | · Many animal fibers have good moisture-wicking properties, keeping wearers dry and comfortable. | · Generally have lower moisture absorption capability |
| Heat Retention | · Animal fibers are known for their warmth and insulation properties. | · Heat-retention properties depend upon their design. |
| Allergenic Potential | · Some individuals may be allergic to certain animal fibers (e.g., wool). | · Generally, synthetic fibers are less likely to cause allergies. |
| Cost | · Can be more expensive due to the care and feeding of animals | · Often more affordable |
| Sustainability | · Wool and pashmina can be sustainable when produced using ethical and eco-friendly practices. | · Synthetic fibers can be less sustainable due to their petroleum-based origin. |
| Biodegradability | · Biodegradable and can naturally decompose | · Not readily biodegradable |
