Types Of Fibre Flashcards
What are short fibre lengths called?
Staple fibres.
Yarns are threads made from tiny “Hairs” called …
Fibres.
What’s are longer lengths of fibres called?
Filaments.
Yarn made from filaments are… (Property)
Smooth.
Yarns made from staple fibres tend to be…
Hairier.
What are natural fibres?
Fibres that come from natural sources - plants and animals.
Give examples of natural fibres and their source.
Cotton and linen from plants, wool from sheep and other animals, and silk from silkworms.
What makes natural fibres more sustainable than other types of fibre
They come from renewable sources and the fibres are biodegradable and often recyclable.
Describe how a yarn of wool is produced.
Wool fibres are harvested from the fleece of a sheet or other animal. The fibres are cleaned and straightened and then spun into a yarn.
What are the properties of natural fibres?
Natural fibres are absorbent and strong when dry, but have poor resistance to biological damage, e.g. From moths and mould.
What is regenerated fibres?
They are fibres made from natural materials (usually cellulose from wood pulp) that are chemically treated.
Why is regenerated less sustainable than natural fibre?
The fibres have a renewable origin, but many are made using synthetic chemicals.
How are regenerated fibres made?
The natural fibre is melted or dissolved in a certain chemical. This liquid is then forced through tiny holes, and hardened to form filament fibres.
Examples of regenerated fibres
Viscose
Acetate
Properties of regenerated fibres.
They tend to have similar properties to natural fibres, but can be given different properties by using different chemicals.
