Worked Solution & Example Answer:Write a profile of a synthetic / man-made fabric under the following headings: • fibre production • properties - Leaving Cert Home Economics - Question 2(b) - 2008
Step 1
fibre production
Answer
A suitable example of a synthetic fabric is nylon. Nylon is produced through a chemical process involving two monomers that are mixed in a ratio of 1:1 to create a long-chain polymer. The production begins when these monomers undergo polymerization in a reactor to form a viscous solution. This solution is then extruded through a spinneret into cool water, where it solidifies into filaments. These filaments are subsequently chopped into chips, which are dried before being transformed into yarn ready for spinning.
Step 2
properties
Answer
Nylon possesses several beneficial properties that make it a popular choice for various applications:
- Strength: It is known for its tensile strength, making it durable and resistant to wear and tear.
- Lightweight: Despite its strength, nylon is lightweight, which adds to its versatility in application.
Step 3
Name and describe one fabric construction technique.
Answer
One common fabric construction technique is weaving. Weaving involves interlacing two sets of yarns, known as the warp and the weft. The warp threads are held taut on a loom, while the weft threads are passed over and under these warp threads in a specific pattern, creating a solid fabric structure. This technique allows for various patterns and textures depending on the interlacing methods used.
