Sustainable Fabrics

Complete Guide to Sustainable Fabric

Clothing is a basic human need but with creativity and innovation, it has become so much more. It can be a symbol of cultural identity or a means of self-expression. Using sustainable fabrics ensures we continue to enjoy wearing lovely clothes without endangering the planet. Fast fashion has made clothing cheap but at substantial costs to the and workers along the supply chain. Fashion should not cost the earth or the dignity of garment workers. Sustainable fabrics help to make this possible by providing sustainable, ethical, and more environmentally friendly materials for our clothes. 

What makes a fabric sustainable

The exact measure of sustainability may differ from person to person, however, you’ll find conventional standards against which we may measure sustainability. Overall, a sustainable fabric should be ethically sourced, have an eco-friendly production process. Further, we should be able to safely dispose of sustainable fabrics once they have reached their end-of-life. Sustainable fabrics do not contribute to the pollution and waste that we know the fast fashion industry for. 

We can determine the sustainability of fabrics with the following criteria:

The first thing that determines how sustainable a piece of fabric is is the raw material used to make it. Most eco-conscious consumers favor natural fibers because they biodegrade.

Other people may consider recycled synthetic fibers sustainable as well. For sustainable fiber sourcing, the planting or extraction process must have a negligible environmental impact, if at all. Fibers whose cultivation or extraction put the environment in danger are not sustainable. 

One natural fiber that seems to have questionable sustainability is cotton. Cotton is one of the dirtiest organic fibers. Cotton farming requires heavy use of pesticides, herbicides, and chemical fertilizers, which pollute the environment and can cause harm to consumers. 

The global organic textile standards (GOTS) and Oeko-Tex certify clothes sewn from natural and chemical-free fabrics.

Also, the renewability of the source material of the fabric is an important criterion. It is impractical to exhaust precious limited resources to make clothing. If we do this, then we are setting up the future generation to suffer from scarcity. Sustainable natural fibers are renewable because we source them from plants and animals without harming the soil or the animals.

Polyester accounts for 65% of fabrics used in the clothing industry. And made from fossil fuel, each synthetic garment comes from a non-renewable resource. The way around this problem is to recycle polyester fabric already in circulation. 

Environmental impact

Eco-friendly production is one of the core concepts of sustainable fashion. According to the EPA’s Resource conservation and recovery act, many textile manufacturing companies generate hazardous waste2.

Fabrics undergo washing, dyeing, and bleaching with synthetic chemicals. These chemicals are unsafe for humans even when exposure is indirect3. Despite concerns for the environment, some factories still release toxic chemical waste into their surroundings, polluting the water supply and endangering humans and wildlife.

On the other hand, they manufacture sustainable fabrics without putting the planet in jeopardy. However, the degree of eco-friendliness varies for each material.

Another thing to consider is the distance the fiber travels before becoming a finished product. Transportation of raw textile materials contributes to the carbon footprint of clothing. Clothing made from materials that have been transported to different locations for every stage of production has a higher carbon footprint than fabrics manufactured locally. Therefore before you purchase imported fabrics, first search for locally made alternatives.

Also, an energy-efficient fabric production process reduces energy consumption and waste. Innovative companies have various methods of production that require less energy and produce fewer waste materials. One such is the closed-loop production system that allows manufacturers to recapture and reuse 99% of the production materials5.

Clothing labeled with EcoCert, Oeko-Tex, Cradle2Cradle, and Bluesign certify fabrics produced without endangering the environment.

Fair labor practices

Our clothes don't produce themselves. Even with all the technology and machines available, human input is still essential. So besides being environmentally friendly, our fabrics must be worker-friendly as well.

Many textile companies source labor from low-cost countries like China, Bangladesh, Vietnam, Cambodia, and so on. These countries attract clients using cheap labor and speedy turnover time. This may be great for fashion retailers but comes at a high cost to the poor workers who sometimes have to choose between unemployment and hellish working conditions at garment factories. 

Whereas they produce sustainable fabrics without social injustice. They pay the workers fair wages for the labor they provide. Also, the work environment is safe, with no dangers to the life and health of the workers. A third party has examined fabrics with Fair Trade certification or Fair Wear approval. The fair external auditors determine that the company manufactured them in ways that don't infringe on anyone's human rights.

Of course, with a bit of research, you can start to understand the exact practices which earned the clothing brand its certificates. 

Why should you choose sustainable fabrics?

The fashion industry’s impact on the planet requires that consumers take steps to ensure their fashion choices are sustainable. And this starts with knowing what material is sustainable.

Waste reduction 

The world produces about 92 million tonnes of textile waste every year. We can put some of the blame for the enormous waste on fast fashion’s policy of quantity over quality.

Clothing made from unsustainable fabrics damages easily. This is why a lot of clothing ends up in landfills too quickly. By 2025 municipal solid waste would have increased by 70%6. This will cause an increase in pollution, which the planet doesn't need more of. So choose high-quality, sustainable fabrics as they can help to reduce post-consumer textile waste.

You’ll find sustainable fabrics more durable and made to last. They are made carefully considering the environment and workers, which often results in high-quality fabrics. Sustainable fabrics can stand the test of time, endure wash and wear while maintaining quality. This makes them a lot more recyclable than regular fabrics. You can swap or resell your clothing after years of use when it is produced sustainably. 

Less pollution

Presently the fashion industry is the second largest contributor to environmental pollution. The sector is responsible for 10% of global greenhouse gas emissions, which contributes to global warming. 

One quality of sustainable fabrics is that they pollute the environment significantly less than their unsustainable counterparts. If they do release pollutants at any point during their production, the amount is usually minor compared to fabrics considered unsustainable. Recycling, closed-loop process, and eco-friendly production material and methods are the marks of sustainable fashion.

Resource conservation

Water is one resource most pressured by the textile industry. About 20% of the world's wastewater comes from the fashion industry.

Whereas the production of sustainable fabrics uses closed-loop systems that collect wastewater and other materials from the production process and recycles them repeatedly. 

Another resource that sustainable fashion aims to protect is soil. The soil is more than just ground to walk on or a bed for crops. It is a habitat for organisms vital to the ecosystem. Sustainable fashion ensures that farming practices do not damage the soil as such damage can affect the ecosystem negatively. 

Fair labor 

When you buy sustainable fabrics from socially responsible companies, you are helping to ensure fair labor in the fashion industry.

Types of sustainable fabrics

Many different fabrics have the word sustainable attached to them. Below is a list of top choices.

Organic cotton

Cotton farming consumes a lot of water. The Aral sea is currently about 10% of its original size, and cotton production in the south Asian area is to blame. Conventional cotton consumes 6% of global insecticides and 16% of pesticides. This is more than any other single crop uses. 

Unlike industrial cotton, organic cotton consumes less water, uses no GMO seeds, and requires no chemical fertilizers or pesticides. This implies that organic cotton has less impact on the environment than industrial cotton.

Cotton clothes also need a lot of water. A simple cotton t-shirt requires 2,700 gallons of water to make. There are innovative ways to use less water in producing cotton clothing and prevent waste. Organic cotton fabrics made with resource and energy-efficient systems are the best choice. The GOTS certification is one of the many certificates issued for organic cotton fabrics.

Organic Linen

Linen for clothing dates as far back as ancient Egyptian civilization. They make it from the fibers of the flax plant, which we can find in Europe. The flax plant does not require many pesticides or fertilizers to grow and is biodegradable. Further, it is not water-intensive like cotton and does not damage the soil. It is durable and can last for years. It also has moisture-wicking qualities. Linen has many great qualities, but the organic version is better.

They produce organic linen with no harmful chemicals. It is unbleached and usually left with its natural hues of ivory, grey, tan, and ecru. This also means that manufacturers have applied no harmful chemical dye. They grow it without chemical fertilizers, pesticides, and herbicides. The entire process of producing organic linen is chemical-free. When you buy linen clothing, go for linen with organic and fair trade certifications.

Bamboo is one of the fastest-growing crops in the world, and it doesn't need any fertilizer. Its rapid growth rate and self-regeneration make it a highly sustainable source material for textiles, amongst other things.

Bamboo fabric is hypoallergenic and great for people with sensitive skin. It is also durable, moisture-wicking, and biodegradable. Bamboo is softer than cotton and has a silk-like feel to it. There are three types of fabric made from bamboo; bamboo rayon, bamboo lyocell, and bamboo linen. 

Producers make bamboo rayon using a chemically intensive process, and the result is a finished product more synthetic than natural. They produce bamboo linen, on the other hand, with an eco-friendly, although time-consuming mechanical method. This fabric is not as soft as bamboo rayon, but they regard it as the ‘original’ bamboo fabric. You’ll likely have to shop around for it as it’s become something of a niche product.

They produce bamboo lyocell in a closed-loop system and consider it a greener alternative to viscose rayon. Although bamboo lyocell is expensive compared to its rayon, the lyocell process is an eco-friendly option because it uses less toxic chemicals and creates no waste.

This type of fabric is a semi-synthetic fabric made from the pulp of beech trees. They originally developed modal in Japan as an alternative to silk. Clothing companies commonly use it in manufacturing activewear, underwear, bathrobes, pajamas, and beddings. In addition to being breathable and silky smooth, modal is stronger compared to rayon. It has a high resistance to shrinkage and pilling, and it is pretty absorbent. 

They produce modal in a similar process to viscose rayon; however, it requires less sodium hydroxide and produces less waste.

Lenzing AG is an Austrian company that manufactures TENCEL Modal, a trademarked version of modal that is better for the planet. They make their modal fabric from sustainably sourced beech trees. The company assures consumers its modal is carbon neutral and made with a closed-loop process.

When you shop for modal fabrics, look out for those with FSC or PEFC certifications. This shows that the manufacturer sourced them in a way that does not adversely affect the forests.

Recycled polyester

Polyester is one of the most frowned upon fabrics in sustainable fashion. This is because they make it from a non-renewable material. It takes about 70 million barrels of oil to produce a year’s supply for the world. Polyester is not biodegradable. It breaks down into microplastic fibers that get into water systems and cause pollution. These microplastics are harmful to marine life and consequently to humans who consume them.

However, for practical reasons, polyester remains a top choice in the fashion industry. Therefore recycled polyester is a sustainable option when polyester is necessary. It reduces the need for virgin polyester, and also, they can use various plastic items like plastic bottles to produce recycled polyester fabric. The recycled polyester fabric helps to keep plastic out of landfills and reduces plastic pollution. The recycled material also emits less CO2 than virgin polyester. 


Industrial hemp is the variety of cannabis plants used in textiles production. Hemp grows fast,  can survive in a variety of climates, and it is soil-friendly. Hemp is a high-value crop that has uses beyond textiles. We use it in medicine, food, cosmetics, construction, and more. Almost no part of the plant goes to waste. 

Hemp cultivation does not need herbicides as the plant will naturally overtake competing plants. Also, the plant is pest-resistant, so it rarely requires pesticides. The plant requires little water to thrive. Even in fabric production, hemp consumes less water than conventional cotton. It takes about 10,000 liters of water to produce 1kg of cotton, while just 500 liters will produce 1kg of hemp fabric1. Also, hemp fabric processing is not chemically intensive. These qualities make it environmentally sustainable. 

Pure hemp fabric has a similar texture to linen and is more durable than cotton. Just like bamboo, hemp has hypoallergenic qualities and is breathable. Manufacturers also blend hemp fiber with other plant-based or synthetic fibers.

Hemp fabrics labeled ‘hemp viscose’ are as bad for the planet as regular viscose. So make sure to look beyond the ‘hemp’ tag in clothing. Seek hemp fabrics with certifications that prove they are organic, fair trade, and ethically produced.

Silk is a natural fiber from silkworms. Often considered a luxury material due to its price and feel, natural silk is soft, breathable, and feels warm in the winter but cool in summer.

Silk is biodegradable and produces little waste during manufacturing. Producing silk is not water-intensive. The bombyx Mori silkworms survive on mulberry tree leaves, a sustainable feed source because the tree is pest-resistant and grows easily. Silkworms may be tiny, but just like other animals, it is unethical and inhumane to harm them in producing silk. 

The traditional method of making silk involves collecting the cocooned worms and boiling them to separate the silk. They do this to ensure the silk fibers do not break. However, With this method, 5,000 silkworms may have to die to produce enough material for one silk kimono7. In some places, they use the dead worms as a food source, but it results in waste when that is not the case. 

Peace silk allows the worms to develop into moths and leave their cocoon. They then collect the empty silk cocoons and process them. Some manufacturers also use wild silkworms raised in environments that mimic their natural habitat. 

Choose silk with GOTS, fair trade, cruelty-free international or OTEX certifications.

sustainable wool

Wool is one of the most loved natural fibers. It provides incredible warmth and is biodegradable and recyclable. Wool is durable, flame resistant, and moisture-wicking.

We harvest wool from the coat of hair found on the angora rabbits, sheep, alpacas, and goats. If producers don't harvest the wool, it will grow into a heavy coat that disturbs free movement. Wool is renewable as we don't have to kill animals to source the material for our favorite wooly jumpers.

Only buy wool produced under cruelty-free conditions. There are concerns about unethical wool production that neglect the welfare of animals and focus on profits.

Farmers harvest ethical wool in the warmer season of the year so that the animals are not at risk of complications from cold. Also, ethical wool farmers encourage hand shearing to prevent accidental cuts and avoid frightening the animal. The angora rabbit molts every four months, so it is most ethical to collect the fallen hair. Also, research has shown that wool reacts well to natural and sustainable dyes4

Some certifications sustainable wool fabrics may have; Responsible Wool Standard, ZQ Merino Standard, Certified Organic Wool and Certified Animal Welfare Approved.

TENCEL lyocell

They make lyocell from cellulose found in wood pulp. The trade name TENCEL belongs to an Austrian company that produces it.

Lyocell is biodegradable and easily compostable. This makes it easy to dispose of when it has come to the end of its life cycle. The manufacturing process produces minimal waste and reduced wastewater through recycling and reuse. Also, lyocell production does not require the use of toxic chemicals.

Deadstock/ reclaimed fabric

Eco-conscious people agree that buying second-hand clothes is a great way to make fashion circular and sustainable. Buying second-hand fabrics from recycled cotton and others also have the same advantage.

Clothing factories usually have leftover fabrics. This could happen when the factory purchases large amounts of stock, but fast fashion trends change so quickly that these fabrics become obsolete. The fate of deadstock fabrics is the landfill, but these fabrics can be reclaimed, reused, and sold as vintage goods.

Cupro is soft to the touch and has a fine sheer texture. It works as a great vegan alternative to silk. Manufacturers make Cupro from clothing made with recycled materials. As such, it helps to extend the life of raw materials even further. They make the fabric from cellulose rayon fiber. The cellulose of choice is mostly cotton.

There are concerns about the effects of the chemicals used to dissolve the fiber material. The chemicals include copper, ammonia, and caustic soda. These chemicals are toxic and harmful to factory workers if they do not dispose of them quickly and adequately. 

To ensure that you are buying sustainable cupro, make sure the manufacturer has certifications that show they treat workers fairly. And do not put the lives and health of workers at any risk for the sake of profit.


Down refers to the plumage found underneath the feathers of birds like geese and ducks. It is a by-product of the food industry. The material is fluffy, soft, and biodegradable. They use it as a natural alternative to synthetic insulation for winter coats and sleeping bags. Down itself is not a sustainable fabric. Instead, we use it to fill up clothing meant to provide warmth. It has a high heat-trapping ability and is lightweight. Some manufacturers may add feathers to the down to produce a blend. 

Down is durable, and its insulating benefits can last for decades. There are concerns about animal cruelty in down production, where they subject living geese to painful feather plucking.

In response, the Responsible Down Standard is a method of verifying ethically sourced down. The North Face brand set it up, and other brands have adopted it directly or indirectly. NSF International is an auditing body that helps brands to monitor the practices of their down suppliers. Choose brands that use NSF International or other credible methods to ensure they only use cruelty-free down.
