Bamboo Fabric & Sustainability

As the clothing and textile industry continues to find innovative ways to be sustainable, it explores various types of fabrics. Bamboo fabric is one type of material that people often praise for being sustainable. However, the term ‘bamboo fabric’ houses different types of textiles. While some fabrics are environmentally friendly, others prove less so. The manufacturing process used to make each fabric also gives us an insight into which bamboo fiber is most sustainable. This article serves as a complete guide to understanding bamboo fabric, how its made, and its various uses alongside sustainability.

What is Bamboo Fabric?

Bamboo fabric is a general name for a variety of textiles we acquire from bamboo. These mainly differ based on how producers acquire them. The three main types are bamboo viscose, lyocell-type bamboo fabric, and natural bamboo (also called bamboo linen)3.

The sustainability of bamboo fabric can seem a little complicated at first glance. However, once you understand the properties and processes of each type, it’ll be easy to spot the eco-friendly types. Although this plant has its many advantages as a raw material for fabric and clothes, the type of fabric manufacturers extract from it makes all the difference to the planet. 

Due to its durable and soft nature, we find bamboo fabrics used to make products such as towels, underwear, shirts, and bedsheets. This breathable, soft, and smooth fabric sometimes serves as an alternative to cotton. The textile and fashion industry embraces these properties.

Also, it is often a go-to fabric for people looking for a cruelty-free alternative to silk. While bamboo is natural, the fabrics we get from it are semi-synthetic due to the processing methods. This is especially true for viscose rayon and lyocell-type fabric. To get an understanding of how these types differ, let’s examine the different manufacturing processes.

How is Bamboo Fabric Made?

As mentioned earlier, the different types of bamboo fabric go through various processes before becoming a textile for clothing. It is important to note that the most common bamboo fabric is bamboo viscose.

This textile is significantly cheaper to manufacture and uses the rayon production method. This viscose rayon fiber requires a significant amount of chemicals in its manufacturing process. The lyocell fabric, on the other hand, uses less toxic chemicals. The best and most sustainable is the natural type, which requires mechanical processing. 

Types of Bamboo Fabric and Their Processing

Viscose Rayon Production 

Even though bamboo is used to make this fabric, the process can be toxic to the planet. Some of these chemicals are also harmful to workers. To acquire this fabric, manufacturers apply the conventional viscose rayon production process. As a result, bamboo viscose requires a lengthy process. 

After planting and harvesting the bamboo plant, the workers extract bamboo cellulose from the wood pulp. This involves breaking down wood into small chunks and exposing it to a chemical solvent. Through this, the bamboo cellulose is acquired. The process then goes as follows:

  • You compress the cellulose from bamboo fibers into sheets, process it using carbon disulfide (which is known to be a harmful chemical), and filter it. 
  • Then, you push the cellulose through a spinneret. This process transforms the cellulose into strands. 
  • To soften the strands, you immerse them in another chemical called sulfuric acid. This produces filaments which you spin into yarn. Finally, machines can weave this into the useful fabric for clothes.

This process involves the heavy usage of harmful chemicals such as carbon disulfide and sulfuric acid. 

Lyocell or Closed-Loop Production

Another manufacturing process to acquire bamboo fabric and fibers is using a closed-loop method. Instead of using harmful chemicals like carbon disulfide, this process doesn’t chemically change the cellulose structure.

The closed-loop process, therefore, creates a fabric that is natural and organic. Also, factories dispose of the solvents used to make bamboo rayon in the viscose rayon process. It is classified as waste. On the other hand, they can use solvents in this closed-loop process over again. This leads to a better environmentally-friendly impact. 

Mechanically-Produced 

This method is the most friendly to the environment. The processing doesn’t involve chemicals. Rather, it requires mechanical processing. To acquire these bamboo fibers, you mechanically crush the plants.

Afterward, you add natural enzymes to the crushed wood fibers. You then wash these fibers and spin them into bamboo yarn. The resulting bamboo fabrics are quite costly, and the process is labor-intensive. As a result, it is limited in the market.

History of Bamboo Textiles

Producers utilize bamboo to make a variety of products. For instance, the paper industry uses it in paper production. However, bamboo fibers for clothes came about in the 20th century. It is important to note that there had been attempts over the years to generate fiber to be turned into apparel.

We can trace the origins of bamboo fabric to Asia. We can further trace the development of the first modern process of attaining bamboo textile to Beijing University1. They released the results of usable bamboo apparel in the early 2000s. Around this time, some other manufacturers and organizations were working to create bamboo apparel by using similar methods. 

This successful extraction was developed, and modern bleaching methods were used to turn the fabric white. It then became commercially available and successful in the American market. Over the years, experts have developed methods of generating the fabric. As a result, we’ve noticed innovations in mixing and blending fabrics. 

How Sustainable is Bamboo Fabric?

As a raw material, bamboo is a natural and highly sustainable plant. It has a minimal environmental impact compared with many crops. The crop has many sustainable benefits. These include:

  • Growing quickly with an easy-to-grow nature
  • Maturing quickly
  • Being able to grow on land that may not be suitable for other crops
  • Requiring minimal pesticides
  • Absorbing a large amount of carbon dioxide

So if farmers grow it under favorable conditions and practices, bamboo is quite sustainable. The issue mainly arises for fabric in the production process. For instance, the rayon type goes through a chemical process using carbon disulfide, which is toxic. This leads to air pollution with hazardous effects.

Asides from posing harm to the environment, it also affects the health of the workers. It can cause ailments such as liver damage, blindness, and psychosis. The rayon type is also the most common bamboo fabric. As a result, many brands tend to simply state the material as ‘bamboo’. This can be misleading as it lacks transparency in mentioning the exact type. 

Choosing a Fabric

When choosing bamboo fabric, it is best to look out for the natural one or lyocell-like fabric. However, these fabrics can be harder to find compared with bamboo rayon. The fabrics that go through the intensive chemical process often lose the benefits originally provided by the plant. The chemical processes manufacturers employ to produce the material greatly affect the beneficial natural qualities of bamboo.

Due to false and misleading claims from brands, The Federal Trade Commission has compelled brands and companies to label ‘rayon made from bamboo’ when the material is not the natural type. The body created this regulation to protect consumers from false claims within the industry. 

The best and most sustainable type of bamboo is natural bamboo, sometimes called bamboo linen. This one is processed mechanically, thereby avoiding the release of toxic chemicals. 

Bamboo Textile Pros and Cons

Fashion brands recognize the usefulness of bamboo, leading to wider usage of the fabric. Apparels made from this include socks, underwear, and t-shirts. Brands also use bamboo fabrics to make household products like bedding, blankets, and towels. In this section, we’ll examine the benefits as well as the cons of this fabric. 

Pros of Bamboo Fabric

  • Does not Require Pesticides: One of the significant benefits of using bamboo for fabrics is that growing it doesn’t require pesticides. The plant contains a natural antimicrobial bio-agent called bamboo-kun2. The presence of this substance means there is no need for pesticides when growing the crop.
  • Easily Organically Grown: Bamboo is the quickest growing woody plant in the world4. It is easy to grow and this makes it a go-to crop for making bamboo fabric.
  • Soft with Moisture-Wicking Properties: Bamboo fabric is soft and friendly to the skin. The fabric also keeps you dry by drawing moisture or sweat from your skin. 

It is important to note that most of the beneficial properties of this plant are found in the type of fabric that is mechanically processed. The rayon type often lacks many of these qualities.

Cons of Bamboo Fabric

Any bamboo fabric that undergoes chemical processing, involving carbon disulfide, poses a danger to the environment. The chemicals used to process the fabric are harmful to human health and the environment. 

  • Hazardous Emissions: Any bamboo fabric that undergoes chemical processing, involving carbon disulfide, poses a danger to the environment. The chemicals used to process the fabric are harmful to human health and the environment.
  • Shrinkage of the Fabric: Bamboo fabric tends to shrink at a faster rate compared to cotton.
  • Expensive: Natural bamboo fabric tends to be more expensive than the rayon type or even cotton. It is not as common as the bamboo rayon fabric and would therefore cost more.
  • Prone to Wrinkles and Pilling: The bamboo fabric easily wrinkles compared to other materials. It is also prone to pilling. Pilling refers to those small fiber balls that form on clothes. 

Brands that Use Bamboo 

Here, we’ve given a spotlight to some brands that utilize this fabric. Their processes also show their commitment to sustainability.

Bamboo Fiber vs. Others

Organic cotton and hemp are two materials that brands use as substitutes for bamboo. Below, we’ve highlighted some differences between bamboo and these other fabrics:

Bamboo vs. Hemp 

Hemp fabric is a more sustainable choice compared to bamboo. Its manufacturing and production methods are more eco-friendly. Also, the hemp fabric can retain a higher amount of beneficial properties in the final fabric or material. Although bamboo is softer on the skin, hemp is more durable. 

Bamboo vs. Cotton 

The bamboo plant is more sustainable than cotton. However, the processing of bamboo rayon sometimes makes cotton production seem like a better choice. Bamboo crops require less water compared to the amount required for growing cotton. It is also pest-resistant and doesn’t require fertilizers, unlike cotton. Also, bamboo consumes less water - even less than that needed for organic cotton. 

Conclusion

Bamboo is a highly sustainable crop. However, it is important to pay attention to the type of bamboo fabric used in the clothes you purchase. The most sustainable type is bamboo linen. To avoid falling victim to greenwashing, always confirm a company’s transparency concerning the type of fabric used. This also includes processing techniques. Generally, the industry has come a long way in identifying innovative techniques to uphold sustainability.
