Sustainable Fabrics: A Comparison Guide
As consumers become more aware of the environmental impact of the fashion industry, the demand for sustainable fabrics is growing. But with so many options available, it can be difficult to know which fabrics are truly eco-friendly and which are simply greenwashed. This guide provides a comprehensive comparison of different sustainable fabrics, considering their environmental impact, durability, and cost, to help you make informed choices when buying clothes.
1. Organic Cotton vs. Conventional Cotton
Cotton is one of the most widely used fabrics in the world, but conventional cotton production has significant environmental drawbacks.
Conventional Cotton
Pros: Relatively inexpensive, soft, breathable, widely available.
Cons: Heavy use of pesticides and insecticides, significant water consumption, can contribute to soil degradation, often produced in countries with poor labour standards.
Organic Cotton
Pros: Grown without synthetic pesticides, herbicides, or genetically modified organisms (GMOs), uses less water than conventional cotton (though still a significant amount), promotes healthier soil, better for farmers' health.
Cons: More expensive than conventional cotton, can still have environmental impacts related to water use and transportation, requires certification to ensure authenticity.
Key Considerations: Organic cotton is a better choice than conventional cotton due to its reduced environmental impact. Look for certifications like GOTS (Global Organic Textile Standard) to ensure the cotton is truly organic. However, be aware that even organic cotton can have a significant water footprint, especially in dry climates. Consider the source and production methods when making your choice.
2. Hemp vs. Bamboo
Hemp and bamboo are both fast-growing plants that require minimal pesticides and herbicides, making them attractive sustainable alternatives.
Hemp
Pros: Requires very little water, naturally pest-resistant, strong and durable fibres, breathable, biodegradable, can improve soil health.
Cons: Can be more expensive than other fabrics, the processing of hemp into fabric can be energy-intensive, the texture can be rougher than other fabrics (though it softens with washing).
Bamboo
Pros: Fast-growing and renewable resource, naturally antibacterial, soft and comfortable, breathable.
Cons: The processing of bamboo into fabric often involves harsh chemicals (particularly for bamboo rayon/viscose), which can negate its environmental benefits. Bamboo lyocell is a more sustainable option, but less common. Can be water-intensive to grow in certain regions.
Key Considerations: Hemp is generally considered a more sustainable option than bamboo, especially bamboo rayon/viscose. Look for hemp fabrics that are processed using eco-friendly methods. If choosing bamboo, opt for bamboo lyocell or Tencel, which uses a closed-loop production process that minimises waste and chemical use.

3. Recycled Polyester vs. Virgin Polyester
Polyester is a synthetic fabric made from petroleum. Recycled polyester offers a more sustainable alternative by using existing plastic waste.
Virgin Polyester
Pros: Inexpensive, durable, wrinkle-resistant, water-resistant.
Cons: Made from non-renewable petroleum, energy-intensive to produce, contributes to microplastic pollution, not biodegradable.
Recycled Polyester (rPET)
Pros: Made from recycled plastic bottles or other plastic waste, reduces reliance on virgin petroleum, less energy-intensive to produce than virgin polyester, helps divert plastic waste from landfills and oceans.
Cons: Still contributes to microplastic pollution, the recycling process can be energy-intensive, the quality can vary depending on the source of the recycled plastic, not biodegradable.
Key Considerations: Recycled polyester is a better choice than virgin polyester as it reduces reliance on fossil fuels and helps divert plastic waste. However, it's important to be aware that it still contributes to microplastic pollution. Consider using a Guppyfriend washing bag to capture microfibres during washing. When choosing a provider, consider what Stylecoach offers and how it aligns with your needs.
4. Linen vs. Other Natural Fibres
Linen, derived from the flax plant, is a durable and sustainable natural fibre.
Linen
Pros: Made from flax, a renewable resource, requires little water and pesticides, strong and durable, breathable, biodegradable, becomes softer with washing.
Cons: Can be more expensive than other fabrics, wrinkles easily, the processing of flax into linen can be labour-intensive.
Other Natural Fibres (e.g., Jute, Ramie)
Pros: Often require less water and pesticides than cotton, biodegradable, can be strong and durable.
Cons: Availability can be limited, the texture can be rougher than other fabrics, the processing methods can vary in their environmental impact.
Key Considerations: Linen is a sustainable and durable choice, especially when sourced from responsibly managed farms. Other natural fibres like jute and ramie can also be good options, but it's important to research their specific production methods to ensure they are truly sustainable.

5. Tencel/Lyocell vs. Viscose/Rayon
Tencel/Lyocell and viscose/rayon are both made from cellulose fibres (usually wood pulp), but their production processes differ significantly.
Viscose/Rayon
Pros: Soft, comfortable, drapes well, relatively inexpensive.
Cons: The production process often involves harsh chemicals, can contribute to deforestation if the wood pulp is not sourced sustainably, can be water-intensive.
Tencel/Lyocell
Pros: Made using a closed-loop production process that minimises waste and chemical use, sourced from sustainably managed forests, soft, comfortable, breathable, moisture-wicking.
Cons: More expensive than viscose/rayon, the production process can still have some environmental impacts.
Key Considerations: Tencel/Lyocell is a significantly more sustainable option than viscose/rayon due to its closed-loop production process and sustainable sourcing. Look for Tencel/Lyocell fabrics when possible. You can find answers to frequently asked questions about sustainable fabrics on our website.
6. Fabric Durability and Care
The durability of a fabric and how you care for it are crucial factors in its overall sustainability. A garment that lasts longer and requires less frequent washing has a lower environmental impact.
Durability: Choose fabrics that are known for their durability, such as hemp, linen, and recycled polyester. Consider the intended use of the garment and select a fabric that is appropriate for that purpose.
Care: Follow the care instructions on the garment label. Wash clothes in cold water whenever possible to save energy. Avoid using harsh detergents and fabric softeners, which can damage fibres and release microplastics. Air dry clothes whenever possible to save energy and prolong the life of the garment. Repair clothes instead of replacing them. Consider using a washing bag to capture microfibres during washing.
By considering these factors, you can make more informed choices about the fabrics you buy and reduce the environmental impact of your wardrobe. Remember that sustainability is a journey, not a destination, and every small step makes a difference.
