Materials And Their Applications Flashcards
What are the characteristics of a school shirt?
Strong, hard wearing, comfortable, easy to care for
What is a fibre?
A fine hair-like thread that can be spun with others to make a yarn
What is a synthetic fibre?
A fibre made entirely from synthetic polymers based on oil
What is meant by being Sustainable?
Ensuring that all aspects of design and manufacturing dont have a negative impact on the environment or human lives
What is a natural fibre?
A fibre that comes from natural cellulose or protein
What is a regenerated fibre?
A fibre from natural cellulose that has been chemically modified
What is a polymer?
A long chain of molecules made up of fibre forming atoms that are linked together
How are woven or knitted fabrics made?
Fibres are twisted (spun) together to make a yarn and then from there they can be used to make a woven/knitted fabric
Natural fibres:
What are plant fibres made from?
What are animal fibres made from?
Cellulose
Protein
Natural plant fibres examples:
Cotton, linen and ramie
Natural animal fibres examples:
Wool and silk
Examples of regenerated fibres:
Mostly made from natural cellulose from wood pulp or waste cotton fibres too short to be spun into a yarn so chemically treated to modify the cellulose so it can be made into fibres
Examples of regenerated (first generation manufactured fibres)
Viscose, rayon
What are some examples of second generation fibres?
Modal and lyocell
What is the most environmentally fibre?
Rayon
Viscose
Lyocell
Lyocell are more environmentally friendly fibres because they are manufactured using a closed-loop system that reuses chemicals in the process
