Question 1: Describe the main characteristics of cotton fabric, including its texture, appearance, and common uses.

Answer: Cotton fabric is soft, breathable, and has a smooth texture. It is usually white or natural in color and is commonly used for clothing, bed linens, and towels.

Question 2: Explain the differences between wool and polyester fabrics in terms of their properties and typical applications.

Answer: Wool is a natural fiber that is warm, elastic, and insulating, often used in winter clothing and suits. Polyester is a synthetic fiber that is durable, resistant to shrinking and stretching, and used in everyday clothing, sportswear, and furnishings.

Question 3: Identify and list three fabrics that are suitable for making sportswear. Provide reasons for your choices.

Answer: 1. Polyester – lightweight, quick-drying, and durable. 2. Nylon – strong, stretchy, and resistant to wear. 3. Spandex (Lycra) – highly elastic, allowing for stretch and movement.

Question 4: Describe the process of how viscose fabric is made from natural cellulose sources.

Answer: Viscose is made by dissolving cellulose from wood pulp or cotton linters in chemicals to form a viscous solution. The solution is then extruded through spinnerets to create fibers, which are washed, softened, and spun into yarns for fabric production.

Question 5: Sketch a simple pattern for a fabric that combines two different textures, such as smooth and rough. Label the areas that represent each texture.

Answer: A correct sketch would show a fabric divided into two sections: one smooth, possibly with a shiny or flat appearance, and the other rough, with a textured or fuzzy look. Labels should clearly indicate 'smooth texture' and 'rough texture'.

Question 6: List two advantages and two disadvantages of using silk fabric.

Answer: Advantages: 1. Soft, luxurious feel; 2. Attractive sheen and drape. Disadvantages: 1. Expensive and delicate; 2. Difficult to clean and maintain.

Question 7: Explain why linen fabric is often used for summer clothing.

Answer: Linen is breathable, lightweight, and absorbs moisture quickly, making it comfortable to wear in hot weather. Its natural fibers help keep the body cool.

Question 8: Identify which fabric type is most suitable for making a heavy-duty work jacket and justify your choice.

Answer: Canvas or denim would be suitable because they are thick, durable, and resistant to wear and tear, making them ideal for workwear.

Question 9: Describe the differences between synthetic fabrics like polyester and natural fabrics like cotton in terms of environmental impact.

Answer: Natural fabrics like cotton are biodegradable and require fewer chemicals for production, but cotton farming can use a lot of water and pesticides. Synthetic fabrics like polyester are made from petrochemicals, are not biodegradable, and contribute to microplastic pollution, but they require less water and land to produce.

Question 10: Draw a cross-section of a fabric showing the basic layers or fibers that make up woven fabric. Label the warp and weft threads.

Answer: A correct sketch would depict a grid-like pattern with two sets of threads crossing at right angles. The vertical threads are labeled as 'warp', and the horizontal threads as 'weft'. The threads should be shown interlacing over and under each other.
