Bamboo viscose has become a popular textile material in recent years, thanks to its eco-friendly nature and luxurious feel. It is derived from bamboo plants, which are fast-growing and do not require any harmful pesticides or fertilizers to grow the crop.
However, the credentials of bamboo viscose as an eco-friendly fabric can only be understood once you know how it has been extracted from the plant.
The fibres used in 100% Bamboo fabric can be extracted in two ways: mechanically and chemically.
Mechanical Extraction:
Mechanical extraction involves crushing the bamboo stalks into a pulp, which is then washed and spun into fibres. This process does not use any chemicals or solvents, making it a more eco-friendly option. It is also considered to be more sustainable as it uses less water and energy compared to chemical extraction. The resulting fibres are durable, strong, and have a natural shine and softness to them.
Chemical Extraction:
Chemical extraction involves using chemicals such as sodium hydroxide and carbon disulphide to break down the bamboo fibers into a pulp. This process also involves the use of sulphuric acid to dissolve the pulp, which is then spun into fibres.
There are several reasons why mechanical extraction is considered better than chemical extraction. Firstly, it is more eco-friendly as it does not use harsh chemicals that have the potential to harm the environment. Mechanical extraction also uses less water and energy, making it a more sustainable option.
100% Bamboo fabric produced through mechanical extraction also tends to have more of a natural shine and more of a luxurious feel to it. As consumers, it is important to be aware of the production process of the products we buy, and opting for mechanically extracted bamboo viscose is a great way to support sustainable and eco-friendly practices within the industry.
