Fibres and fabrics - OCRProperties

Textiles are made from fibres, classified as either natural or manufactured. Fibres are twisted into yarns before being made into woven, knitted or bonded fabrics.

Properties

Material are vital to consider when creating a textiles product, as the functionality of a fabric can make it a success or a failure. For example, a non-absorbent bath towel or a warm sundress would not be .

Natural fibres

Natural fibres are all derived from vegetation, cellulose-based materials, as well as products that are made from animals.

Synthetic fibres

Synthetic fibres are human-made fibres produced in a laboratory. They are made from either polymers that are derived from , or naturally sourced materials which undergo a chemical process.
