Understanding Natural Fibres

What are natural fibres?

• Synthetic fibres made from petroleum products.

• Natural fibres are materials obtained from plants, animals, or minerals that are used to make textiles.

• Materials that are only derived from synthetic processes.

• Fibres that are exclusively used in construction materials.

Name two animal fibres mentioned in the text.

What is the primary raw material used in the manufacture of rayon?

• Cellulose

• Polyester

• Nylon

• Acrylic

What is the most popular rayon fibre?

• Modal

• Viscose

• Lyocell

• Acetate

How are synthetic fibres created?

• Synthetic fibres are created by polymerization of monomers into polymers, which are then extruded into fibres.

• Synthetic fibres are formed through the spinning of metal threads.

• Synthetic fibres are created by weaving together animal hair.

• Synthetic fibres are made from natural plant materials.

What are spinnerets used for in fibre production?

• Spinnerets are used to extrude synthetic fibers in fiber production.

• Spinnerets are used to dye natural fibers.

• Spinnerets are used to weave fabrics together.

• Spinnerets are used to cut fibers into lengths.

List one advantage of man-made fibres over natural fibres.

• Increased durability and resistance to moisture.

• Better breathability and comfort than natural fibres.

• More environmentally friendly than natural fibres.

• Lower cost of production compared to natural fibres.

What properties must textile fibres possess?

• Strength, flexibility, durability, moisture absorption, thermal insulation, chemical resistance.

• Non-absorbent and rigid

• Highly flammable

• Lightweight and airy

How do man-made fibres compare to natural fibres in terms of moisture absorption?

• Natural fibres absorb moisture better than man-made fibres.

• Natural fibres do not absorb moisture at all.

• Both man-made and natural fibres absorb moisture equally well.

• Man-made fibres absorb moisture better than natural fibres.
