1. History of organic bamboo fabric
Thousands of years ago, people used wood pulp from bamboo trees to make handmade paper. In 1881, weavers combined bamboo fiber with wool to create a new type of fabric that was softer, known as bamboo fabric.
The process of extracting bamboo fiber was first recorded at Peking University in China. In 2000, by using solvents and bleaching agents, the bamboo gum was removed, and since then, bamboo fabric has been widely produced and developed.
Prior to that, fabric made from bamboo fiber had been produced in East Asia for thousands of years. For example, India and China have produced this type of fabric for many generations. Today, festivals honoring bamboo fabric are still held annually in some rural areas of India.
The sustainable nature of bamboo cultivation has driven bamboo production worldwide. Bamboo fabric production is even popular in Western countries such as the United States and Europe because bamboo can grow in various climates. Therefore, most developing countries produce or export a certain amount of bamboo fiber fabric.
However, China is the largest producer of this type of plant. Over the past millennium, bamboo has become an integral part of Eastern cultures such as China, Vietnam, and India.
1.2. Different methods of processing bamboo into Fabric
To produce bamboo fabric, we have two processing methods: mechanical and chemical.
To obtain bamboo fiber, the finest part of the bamboo plant is used, and it is stripped into the thinnest fibers, which are then spun and woven into fabric. Finally, the fabric is dyed.
The bamboo material is ground into pulp and then processed into fiber using the artificial cellulose spinning method, employing specialized chemicals.
Fabric made from bamboo fiber has been around for thousands of years, but it is only in modern times, with the addition of advanced technology, that bamboo fiber fabric has been perfected and possesses the superior characteristics we see today.
NOW, let’s delve into the detailed process of how bamboo is transformed into fabric.
2. The process of transforming bamboo into fabric
The production process of bamboo fabric requires various stages of processing, depending on the specific type of bamboo fabric. Currently, there are two production processes used to create fabric from bamboo: the mechanical process and the chemical process.
First, the bamboo trees need to be harvested.
Compared to other types of timber, bamboo grows much faster. Within 2 to 4 years, bamboo is mature enough for harvesting. After being harvested, bamboo is transported to the production facility and cut into smaller pieces. Cutting the bamboo into smaller sections makes transportation more convenient and lighter.
2.1. Mechanical method – bamboo into fabric
To create bamboo fabric, manufacturers commonly employ the mechanical production method. This method is entirely environmentally friendly and produces highly sustainable fabric.
Step 1: Mechanical Processing
After being crushed, the bamboo is subjected to enzymatic treatment to break down the natural structure of the fibers. The resulting mixture is spread out and stretched into raw fibers, which are further processed in the factory to produce bamboo or linen fabrics.
This method boasts several advantages, including its eco-friendliness and the production of highly durable fibers. However, it does require a significant amount of time.
Step 2: Chemical Processing
In this stage, manufacturers soak the crushed bamboo pieces in a 15-20% NaOH solution at a temperature of around 20℃ for 1-3 hours to create an alkali cellulose type. The alkali cellulose is then pressed, washed to remove NaOH, and dried for approximately 24 hours.
The resulting cellulose fibers are passed through oil sprays and then placed in large tanks containing diluted H2SO4 to harden the fabric fibers and form cellulose, which is then drawn into complete bamboo fibers.
Step 3: Dyeing
Bamboo fiber fabric is highly sensitive to acids and alkalis, so when dyeing the fabric, it is crucial to carefully measure the dye to ensure compatibility. To minimize risks, it is recommended to use reactive dyes as they can react with the bamboo fibers in a mildly alkaline environment.
2.2. Chemical method – bamboo into fabric
In addition to the mechanical method, bamboo fabric can also be produced using a chemical process.
Step 1: The crushed bamboo is immersed in a 15-20% Sodium Hydroxide (NaOH) solution at a temperature of 20-25 degrees Celsius for approximately 3 hours. This step aims to create Alkali Cellulose.
Step 2: Next, the Alkali Cellulose is pressed and separated from Sodium Hydroxide. It is then placed in a dryer for about 24 hours.
Step 3: The Bamboo Cellulose fibers are passed through spinnerets and immersed in a diluted Sulfuric Acid solution to harden the fibers.
Step 4: Finally, the complete bamboo fabric is pulled out in the form of fibers.
3. Common types of bamboo fabric
Apart from the mentioned methods, bamboo fabric can also be created by combining multiple layers of bamboo fibers, resulting in three different materials:
- Viscose Bamboo Fabric: This type of bamboo fabric is similar to synthetic fabrics made from wood pulp. Bamboo is used in its production to reduce costs.
- Lyocell Bamboo Fabric: This fabric is similar to viscose fabric, but it is produced through a closed-loop method, resulting in a naturally sourced and organic fabric.
- Mechanical Bamboo Fabric: This type of bamboo fabric is produced using a mechanical method, without the use of chemicals, ensuring environmental friendliness. Mechanical bamboo fabric is durable, soft, and breathable.
4. Frequently Asked Questions (FAQs)
4.1. Is the process of turning bamboo into fabric environmentally impactful?
The bamboo fabric production process can have an impact on the environment, but the extent of this impact depends on the specific manufacturing methods and processes used. Here are some factors that can affect the environment during bamboo fabric production:
+ Bamboo harvesting: If bamboo harvesting is not carried out sustainably and with proper planning, it can lead to soil degradation and negative impacts on natural ecosystems.

Additionally, enhanced management and sustainable certifications within the textile industry can help minimize the environmental impact of bamboo fabric production.
In summary, bamboo fabric production can impact the environment, but with sustainable practices and careful management, this impact can be minimized.
4.2. Is bamboo fabric recyclable?
Yes, bamboo fabric is recyclable. With the natural properties and durability of bamboo fibers, bamboo fabric can be processed and recycled to create new products. The bamboo fabric recycling process involves collection, fiber separation, and reprocessing the bamboo fibers for use in manufacturing new fabrics.
However, the specific recycling process may vary depending on the methods and technologies employed. Recycling bamboo fabric not only helps reduce environmental impact but also allows for resource utilization and decreases waste from the textile industry.
4.3. Does bamboo fabric shrink after washing?
Bamboo fabric tends to shrink after washing to some extent. However, the degree of shrinkage depends on the fabric type as well as the production and post-processing techniques. Some bamboo fabric products have undergone anti-shrinkage treatments but may still experience some level of shrinkage after washing. To maintain the original size of bamboo fabric, it is recommended to follow the manufacturer’s washing and care instructions.
4.4. How to dye bamboo fabric?
There are two methods for dyeing bamboo fabric:
+ The first method is dyeing from bamboo pulp or fibers. In this method, after extracting bamboo fibers, you can proceed to weave the fabric to create the base material. Subsequently, the fabric can undergo the dyeing process to add color.
+ The second method is dyeing on the fabric itself. After completing the process of extracting bamboo fibers, you can pre-dye the bamboo fibers to add color, and then continue to weave the fabric from the pre-dyed fibers. Notably, with this method, there is no need for a separate dyeing process for the fabric, as the finished fabric can be directly produced after weaving.
In conclusion, the information provided above has shed light on the process of transforming bamboo into fabric, enhancing our understanding of bamboo textiles. Through this article, we have come to realize that producing sustainable fiber fabric is far from simple, requiring significant effort, time, and complex processing procedures.
