Worked Solution & Example Answer:2. (b) (i) Differentiate between regenerated and synthetic fibres - Leaving Cert Home Economics - Question 2(b) - 2022
Step 1
Differentiate between regenerated and synthetic fibres.
Answer
Regenerated fibres are created by dissolving the cellulose of plant fibres in chemicals and then reforming it into fibre again. This process typically involves natural materials, allowing regenerated fibres such as viscose and modal to retain some natural properties.
In contrast, synthetic fibres are made from chemical processes using oil, coal, or other protocol-based chemicals. They are 100% man-made, and common examples include polyester and nylon. These fibres do not have natural origins and often possess unique characteristics tailored for specific applications.
Step 2
Explain filament modification, giving two examples.
Answer
Filament modification refers to various techniques used to change or enhance the properties of fabric. These modifications can improve durability, aesthetic qualities, or functional features.
Examples include:
- Blending: Combining different types of fibres to improve characteristics such as strength and texture. For instance, blending cotton with polyester increases durability while retaining comfort.
- Crimping: Introducing wave patterns in fibres, which enhances bulkiness and insulation properties, often used in textiles like fleece.
