Worked Solution & Example Answer:Modern fabrics are given a variety of treatments during manufacture - Leaving Cert Home Economics - Question 2(b) - 2007
Step 1
Explain why fabric finishes are used when manufacturing fabrics.
Answer
Fabric finishes are crucial in enhancing the performance, appearance, and safety of textiles. They serve several purposes:
-
Enhancing Appearance: Finishes can improve the look of fabrics by giving them a glossy or matte finish, making them more aesthetically pleasing.
-
Improving Handle and Performance: Different finishes can alter the feel of the fabric, making it softer, smoother, or more durable, improving its usability in various applications.
-
Preventing Fabric Shrinkage and Creasing: Many finishes are designed to help stop shrinkage and reduce creasing, which is important for maintaining the fabric’s shape and appearance over time.
-
Water Repellency: Some treatments make fabrics water-resistant or waterproof, which adds functionality for specific environments or uses.
-
Flame-Proofing: Chemicals can be applied to fabrics to enhance their fire resistance, making them safer for use in certain industries.
-
Colour Enhancement: Finishes can also involve the use of dyes or treatments that create vibrant colors and patterns on the fabric surface.
Step 2
Name and describe one type of fabric finish.
Answer
One type of fabric finish is the Flame Retardant Finish.
-
Name: Proban
-
Description: Proban is a finish used on cotton, linen, and cellulose fibres. It enhances the fabric's safety by adding an invisible layer of phosphorus and nitrogen to its structure. This finish helps prevent the fabric from melting or smoldering and, in the event of a fire, the flame will self-extinguish. This treatment is essential in protecting individuals in industries where fire risk is higher.
