Answer 2

(b) longer fibres are made into wool for sweaters

Explanation:

• Shorter fibres: Glass fibre and carbon fibre are the most prevalent types of fibres used in short fibre thermoplastics. Short fibre thermoplastic composites are also simpler and less expensive to manufacture than continuous fibre reinforced composites. Fibriils are extremely short and/or uneven fibres. Smaller fibrils jut out and away from the main fibre structure in natural cellulose, such as cotton or bleached kraft.
• Longer fibres:Filaments are any fibres with a practically infinite or infinite length. Staple fibre is any fibre with a practical, limited, or finite length. The length-to-diameter ratio of a continuous fibre is extremely high geometrically. They are typically more rigid and stronger than bulk material. Depending on the fibre, fibre diameters typically range from 0.00012 to 0.0074 in (3-200 m).
