2. What is the difference between natural and synthetic fibres?

Natural fibers are derived from plants, animals, or minerals and are found in nature. Examples include cotton, wool, silk, and hemp. These fibers are obtained through processes such as harvesting, shearing, or extracting from the natural source. Synthetic fibers, on the other hand, are man-made and are produced through chemical processes. They are created using raw materials derived from petroleum-based chemicals or petrochemicals. Examples of synthetic fibers include polyester, nylon, acrylic, and rayon. Some key differences between natural and synthetic fibers include: Source: Natural fibers come from plants, animals, or minerals, while synthetic fibers are manufactured from chemicals derived from petroleum. Production Process: Natural fibers are obtained through processes like harvesting, shearing, or extracting from natural sources, while synthetic fibers are produced through chemical synthesis in industrial settings. Properties: Natural fibers often have unique properties inherent to their source, such as breathability (cotton), warmth (wool), or luster (silk). Synthetic fibers are engineered to have specific properties like durability, water resistance, or elasticity. Environmental Impact: Natural fibers are biodegradable and renewable, making them generally more environmentally friendly. However, the environmental impact of their production and processing can vary. Synthetic fibers, being derived from petrochemicals, are not biodegradable and can contribute to environmental pollution. However, advancements in recycling and sustainable manufacturing processes are mitigating some of these concerns. Cost: The cost of natural fibers can vary depending on factors such as quality, availability, and production methods. Synthetic fibers are often cheaper to produce, making them more affordable in many cases. Comfort: Natural fibers are often praised for their comfort and breathability, while synthetic fibers may sometimes lack breathability and can cause discomfort, especially in hot and humid conditions. Overall, both natural and synthetic fibers have their advantages and disadvantages, and the choice between them often depends on factors such as intended use, cost, sustainability considerations, and personal preferences. read less
