Worked Solution & Example Answer:Differentiated between regenerated fibres and synthetic fibres and give one example of each - Leaving Cert Home Economics - Question 2(b) - 2008
Step 1
Differentiate between regenerated fibres and synthetic fibres and give one example of each.
Answer
Regenerated fibres are derived from natural sources, specifically cellulose from plants, and undergo chemical processing to form new fibres. Examples include:
- Rayon: Made from wood pulp processed through chemical methods.
Synthetic fibres are entirely man-made, produced from petrochemicals and involve a polymerization process. Examples include:
- Nylon: A widely used synthetic fibre made from petrochemicals.
Step 2
blended fabric
Answer
Blended fabric is created by combining two or more types of fibres to enhance the properties of the final material. This method often includes mixing natural fibres like cotton with synthetic fibres, such as polyester, to improve durability, cost-effectiveness, and functionality. For instance, cotton/polyester blends are popular for their versatility and affordability.
Step 3
filament modification
Answer
Filament modification refers to various techniques applied to change or enhance the properties of filament fibres. Techniques include blending, crimping, or altering the surface characteristics of the fibres. For example, polyester can be treated to make it more breathable, while cotton can be brushed to produce a soft, fluffy texture. These modifications can increase resistance to fire, water, and staining, enhancing the overall performance of the fabric.
