Question 1: Define the term 'sustainable design' in the context of textiles. Why is it important?

Answer: Sustainable design in textiles involves creating products using environmentally friendly materials, processes, and practices that reduce negative impacts on the environment. It is important because it helps conserve resources, reduces waste, and promotes ethical production.

Question 2: List three sustainable materials commonly used in textile production and briefly explain the environmental benefits of each.

Answer: ["Organic cotton: Grown without synthetic pesticides or fertilizers, reducing chemical runoff and soil degradation.","Hemp: Requires less water and pesticides, and grows quickly, making it highly renewable.","Recycled polyester: Made from recycled plastic bottles, reducing plastic waste and reliance on fossil fuels."]

Question 3: Describe one method a textile designer might use to minimise waste during the fabric cutting process.

Answer: Using marker planning to optimise fabric layout, ensuring minimal off-cuts and fabric wastage during cutting.

Question 4: Explain the concept of biodegradable textiles and give an example of a biodegradable material used in textiles.

Answer: Biodegradable textiles are materials that can naturally decompose in the environment without leaving harmful residues. An example is bamboo fabric, which is biodegradable and environmentally friendly.

Question 5: Sketch a simple diagram showing a sustainable textile supply chain, including at least three stages. Label each stage clearly.

Answer: A correct sketch would show stages such as 'Raw Material Production,' 'Manufacturing and Processing,' and 'Distribution and Retail.' Each stage should be connected with arrows to indicate flow, and the sketch should be neat with clear labels.

Question 6: Identify two ways consumers can contribute to sustainability when purchasing textiles.

Answer: ["Choosing products made from sustainable or recycled materials.","Buying fewer, higher-quality items that last longer to reduce overall consumption."]

Question 7: Sketch a concept for a sustainable garment design. Focus on using eco-friendly materials and minimal waste. Provide a brief description of your design choices in the space below.

Answer: A correct sketch might depict a simple, versatile garment made from organic cotton or recycled fabric, with minimal seams to reduce waste. The description should mention the use of sustainable materials and efficient construction techniques to minimise fabric waste.

Question 8: Why is it important for textile designers to consider the end-of-life of their products? Provide two reasons.

Answer: To prevent environmental pollution caused by waste, and to promote recycling or biodegradable options, ensuring the product does not persist in the environment after disposal.

Question 9: Explain how using natural dyes can be more sustainable than synthetic dyes in textile production.

Answer: Natural dyes are biodegradable, often produced from renewable resources, and typically require less energy and harmful chemicals during manufacturing, making them more environmentally friendly.

Question 10: Draw a flowchart illustrating the lifecycle of a sustainable textile product from raw material to disposal. Include at least four stages and ensure clarity in your layout.

Answer: A correct flowchart would include stages such as 'Raw Material Harvesting,' 'Manufacturing,' 'Use and Maintenance,' and 'Disposal or Recycling.' The layout should be clear, with arrows indicating progression, and each stage labeled appropriately.
