Bamboo fiber has become known as a standout sustainable option, touted for its versatility and eco-friendly benefits. Some fabrics impact the environment negatively, not only as a product but also from a manufacturing perspective. Consumers are now demanding more and more sustainable options, prompting the textile industry to act. Bamboo fiber is one product born from this need. But does it really live up to the hype?
The Sustainability of Bamboo Fiber
Bamboo fiber comes from the pulp of the bamboo plant, a rapidly growing renewable resource. Some species of bamboo can grow up to 3 feet in a single day. Additionally, this grass doesn't need much water for cultivation and doesn't require the use of pesticides.
Bamboo cultivation is not just sustainable; it is also beneficial for the environment. It helps to reduce carbon emissions and improve soil health. The extensive roots of bamboo prevent erosion, maintaining the land's productivity.
Benefits of Bamboo Fiber
Natural Properties
Bamboo fiber has properties that make it desirable in textiles. For instance, it is incredibly soft, rivaling silk, providing exceptional comfort in clothing. This only applies to chemically manufactured fabric, as mechanically produced textiles are naturally harsher.
Some studies claim that bamboo fabric can inhibit the growth of various bacteria by over 70%, making it a hygienic choice, especially for activewear. Whether this is because of bamboo's naturally occurring antibacterial property or due to the manufacturing process is up for debate. It should be noted that some studies also disagree with this claim, stating that the process of turning the bamboo grass into fabric strips away its antibacterial benefits. Therefore, it would be prudent to take this claim with a grain of salt.
Breathability and Moisture-Wicking
The breathability of bamboo fiber is one of its standout features. The hollow structure of the fiber promotes air circulation, creating a cooling effect on the skin. This makes it ideal for warmer climates or during physical activities. It can absorb moisture and evaporate sweat up to 3-4 times faster than cotton, keeping you dry and comfortable.
Biodegradable
Unlike synthetic fabrics, which create plastic waste, bamboo fiber is completely biodegradable. It decomposes naturally, enriching the soil upon disposal. It is possible that if more consumers switched to biodegradable materials like bamboo, plastic pollution could drop significantly, helping combat environmental issues.
Various Applications of Bamboo Fiber
Bamboo fabric is not limited to clothing and activewear; its versatility makes it suitable for numerous textile products.
Clothing
From casual wear to specialized activewear, bamboo clothing is becoming increasingly popular. With its comfort, breathability, and durability, bamboo fabrics are often chosen for uniforms in industries such as healthcare and hospitality, where comfort during long shifts is crucial.
Home Textiles
Bamboo fiber extends to home textiles such as bed linens, towels, and curtains. For example, hotel chains that use bamboo sheets report higher guest satisfaction due to the luxurious feel and antimicrobial properties, leading to a potential increase in bookings.
Accessories
Bamboo fiber's flexibility also allows for a range of accessories like bags, scarves, and socks. The creative potential of this eco-friendly material caters to consumers who value both style and functionality.
The Different Types of Bamboo Fiber
So far, bamboo smells of roses with all the accolades we have listed. Understanding how bamboo fiber is produced sheds light on its eco-friendly claims.
Bamboo Linen
Bamboo linen undergoes a mechanical process that involves breaking down bamboo shoots using natural enzymes. This method maintains the raw properties of bamboo, resulting in a more environmentally friendly fabric. The production process is quite similar to the one applied to linen and hemp fabrics. Though labor-intensive and yielding lower quantities, it is the preferred method among eco-conscious brands.
It is important to note that the manual method leaves a harsher fabric that is not as soft as chemically processed materials. Additionally, it will wrinkle more and require extra care to maintain. However, it is more durable than the other methods, has a good level of breathability, and does a great job in the absorption of excessive moisture.
Bamboo linen products are not easy to come by. The production cost of this fabric is high, leading only a few consumer-level businesses to utilize it.
Bamboo Rayon
Most fabrics made from bamboo will be bamboo rayon, thus raising concerns about its supposed eco-friendly claims due to its manufacturing process.
The process of making bamboo rayon involves breaking down bamboo by soaking it in caustic soda, also known as sodium hydroxide. This chemical is highly corrosive and can cause severe chemical burns and may induce permanent blindness upon contact with the eyes.
Another chemical used in the manufacturing process is carbon disulfide, a flammable, neurotoxic compound that can be linked to both acute and chronic forms of poisoning, with a diverse range of symptoms.
This process also involves the use of large quantities of water, nullifying bamboo's sustainability benefits by requiring less water during cultivation.
Bamboo Lyocell
Lyocell, less prevalent than its rayon counterpart, is a compromise between sustainability and profitability to some extent. Operating only in a small number of locations, the mills are high-tech and computer-monitored.
It is processed using bamboo cellulose. It uses the organic, biodegradable compound amine oxide. Using a closed-loop system, production waste is not released into the environment. Instead, some of it is filtered and reused.
Conclusion
Bamboo grass is undoubtedly a sustainable resource. Meanwhile, bamboo fabric still holds promising potential as technology continues to develop for its manufacturing process. As it currently stands, one needs to perform a good amount of research when sourcing this fabric to ensure its viability as an eco-friendly and sustainable textile.
