Bamboo fibers are produced in two methods: mechanical process and chemical process.
The mechanical process is the same eco-friendly process used to make linen fibers from flax, therefore, it is also called bamboo linen and it is natural bamboo fiber that can be labeled as bamboo. In mechanical process the bamboo plant is crushed and natural enzymes are used to break the bamboo walls to get natural fibers. These fibers are mechanically scoured out and spun into yarns. Same as flax fibers, bamboo fibers made from this method are short and coarse fibers, so as the yarns and only heavy and coarse fabrics can be woven, no sheeting fabrics can be made with this method
The chemical process is same process as viscose/rayon production. In chemical process, bamboo leaves and woody shoots are dissolved using strong chemical solvents like sodium hydroxide and carbon disulfide. This process is also known as hydrolysis alkalization which is combined with multi phase bleaching. The majority of bamboo fabrics for garments and home textiles, especially bedlinen are made with fibers produced from this method and labeled as viscose/rayon from bamboo
Finally the good news: a new chemical process is developed to produce fibers from bamboo. It is called lyocell (also known by the brand name TENCEL®) process using a closed-loop process to recapture and reuse 99% of the chemical solution, this method also uses much less harmful chemicals, therefore, it is very eco-friendly and can be labeled as lyocell bamboo.
