Why are natural fibers a more sustainable choice in fashion
Natural fibers, such as cotton, linen, hemp, and wool, are generally considered a better choice for apparel making from a sustainability perspective compared to synthetic fibers like polyester, nylon, and acrylic. Here are several reasons why natural fibers are often preferred:
1. Renewable and Biodegradable: Natural fibers are derived from plants or animals, making them a renewable resource. They can be grown or raised again and again without depleting the earth's resources. In contrast, synthetic fibers are derived from non-renewable petrochemicals. When natural fibers are disposed of, they biodegrade, returning to the environment without leaving behind harmful microplastic waste like synthetic fibers.
2. Lower Environmental Impact: The production of natural fibers generally has a lower environmental impact than synthetic fibers. Cultivating and harvesting natural fibers typically requires fewer energy-intensive processes compared to the production of synthetic fibers, which involves chemical reactions and petroleum extraction. Synthetic fiber production also generates greenhouse gas emissions and contributes to air and water pollution.
3. Reduced Carbon Footprint: Natural fibers tend to have a lower carbon footprint throughout their life cycle compared to synthetic fibers. The production of synthetic fibers releases significant amounts of greenhouse gases, contributing to climate change. On the other hand, natural fibers absorb carbon dioxide from the atmosphere during the growth phase, acting as a carbon sink. This carbon is stored in the fiber and can be retained even after it is made into a garment.
4. Energy and Water Efficiency: Natural fiber processing often requires less energy than the production of synthetic fibers. Synthetic fibers go through complex manufacturing processes that involve high temperatures, pressure, and chemical treatments. In contrast, natural fiber processing usually involves higher water consumption level.
While natural fibers have sustainability advantages, it's worth noting that the overall impact of a material depends on various factors, including cultivation practices, processing techniques, and end-of-life disposal. To enhance sustainability further, it is crucial to consider responsible farming methods, efficient water use, non-toxic dyes, recycling programs, and extended product lifecycles through proper care and reuse.
