Worked Solution & Example Answer:Synthetic and regenerated fibres are increasingly used in the production of modern textiles - Leaving Cert Home Economics - Question 2(c) - 2010
Step 1
fibre production
Answer
Manufactured fibres, such as Nylon, start with the mixing of two chemicals called monomers in a 1:1 ratio. This mixture is heated to create a long chain polymer. The fibre is then run onto a water-cooled revolving wheel, which cools the ribbon created during this process. It is subsequently drawn through a cold water tank where it solidifies into chips. Afterward, the chips are dried, melted, and extruded from a small hole. When the molten fibre comes into contact with cold air, it solidifies, allowing it to be spun into yarn for further textile production.
Step 2
properties
Answer
The properties of manufactured fibres like Nylon are extensive. They are very strong and resistant to wear, making them suitable for various applications. The fibres are also crease-resistant, lightweight, and can drape well. Additionally, they possess high abrasion resistance, thereby offering durability. Once washed, they can maintain their shape due to their inherent elasticity and strength. Nylon fibres are also easy to dye and exhibit good fire resistance, as well as being mildew resistant.
Step 3
fabric uses
Answer
Fabrics made from manufactured fibres, such as Nylon, find versatile applications across many sectors. They are commonly used in clothing items like shirts, lingerie, and stockings. Additionally, they are utilized in specialized items such as netting for bridal veils, snow suits, ski clothes, and windbreakers. These fabrics are also employed in home textiles, including knitted dresses, carpets, and soft furnishings.
