Question 1: Describe the properties of cotton fabric that make it suitable for everyday clothing. Include at least two key properties in your answer.

Answer: Cotton fabric is soft and breathable, making it comfortable to wear. It also absorbs moisture well, which helps keep the wearer dry and comfortable.

Question 2: Explain why polyester fabrics are often used in sportswear. Mention at least two properties that make polyester suitable for this purpose.

Answer: Polyester fabrics are durable and have excellent elasticity, allowing them to withstand frequent movement. They also dry quickly, which is beneficial for sportswear.

Question 3: Compare the properties of wool and silk in terms of warmth and texture. Provide a brief explanation for each fabric.

Answer: Wool is a warm fabric with good insulating properties, making it suitable for cold weather. It has a coarse texture but is soft enough for clothing. Silk, on the other hand, is lightweight and smooth, providing a luxurious feel but less insulation.

Question 4: Describe three properties of polyester that contribute to its resistance to environmental factors.

Answer: Polyester is resistant to shrinking and stretching, retains its shape well, and is resistant to many chemicals and environmental conditions like UV rays and moisture.

Question 5: Sketch a fabric sample that is stretchy and elastic. Label the key features that demonstrate its stretchiness.

Answer: A correct sketch would show a fabric with an obvious stretch, perhaps with arrows indicating elasticity in the horizontal and vertical directions. The fabric may appear slightly distorted or pulled to demonstrate flexibility.

Question 6: A fabric is described as being 'hard-wearing' and 'abrasion-resistant.' Which types of fabrics might fit this description, and why?

Answer: Denim and canvas are examples of hard-wearing, abrasion-resistant fabrics because they are thick, tightly woven, and durable, suitable for workwear and outdoor clothing.

Question 7: Explain how the property of breathability affects the choice of fabric for summer clothing.

Answer: Breathability allows air to circulate and moisture to escape, keeping the wearer cool and dry. Therefore, lightweight and breathable fabrics like cotton or linen are preferred in summer clothing.

Question 8: Draw a fabric sample that has high absorbency. Label the features that suggest it is good at absorbing liquids.

Answer: A correct sketch would depict a fabric with a porous, loosely woven structure. Labels should indicate the presence of a high surface area and open weave that allows liquids to soak in easily.

Question 9: Identify two fabrics that are flame-resistant and explain their typical uses.

Answer: Fabrics like aramid (e.g., Kevlar) and treated cotton are flame-resistant. They are used in protective clothing for firefighters, industrial workers, and military applications.

Question 10: Describe how the property of 'elasticity' influences the design of sportswear fabrics.

Answer: Elasticity allows fabrics to stretch and recover their shape, providing comfort and freedom of movement. This makes elastic fabrics ideal for activewear and sports clothing.
