Bamboo Viscose (also known as bamboo rayon) is also known as 'regenerated bamboo', and is a regenerated cellulose fiber that has recently appeared on the market for textiles for apparel and home furnishings. Products from regenerated bamboo are suitable for a wide range of end-uses, such as towels, bathrobes, surgical clothes, bedding, food packaging and even hygiene products such as sanitary pads, surgical masks, bandages and mattresses. Bamboo viscose is in a slightly higher price range than other cellulose fibers, but it does have many advantages to other fabrics. It has exceptional properties such as superior comfort and hand, as well as antimicrobial properties. Since it is classified as a grass, it is one of the world’s most sustainable resources. Bamboo is the fastest growing grass, it can grow up to 119 cm in 24 hours and does not require replanting after harvesting due to the development of a vast root network. The inherent antimicrobial properties of bamboo eliminate the need for pesticides and fertilizers. There is no doubt that growing natural organic bamboo is beneficial to the environment.
How are Bamboo Viscose Fabrics Made?
Regenerated bamboo fibers are produced in a wet-spun process in which natural cellulose (in this case originating from mechanically crushed bamboo leaves and stems) is used as raw material in a hydrolysis–alkalization process (Erdumlu & Ozipek, 2008; Sui et al, 2003). The raw material is obtained from Moso bamboo, and most of the Bamboo Viscose is made in China.
A diluted solution of sodium hydroxide is added to the cellulose sodium xanthogenate, which dissolves it, to afford a viscose solution consisting of about 5% sodium hydroxide and 7–15% bamboo fiber cellulose. After subsequent ripening, filtering and degassing, the viscose bamboo cellulose is forced through spinneret nozzles into a large container containing a diluted sulphuric acid solution, which hardens the viscose bamboo cellulose sodium xanthate and reconverts it into cellulose bamboo fiber filaments. These are cut into staple fibers and spun into bamboo fiber yarns.
BedVoyage Bamboo Fabrics
The terms often used when describing bamboo fabrics are: bamboo viscose, bamboo rayon, and rayon from bamboo. BedVoyage use rayon from bamboo because it is naturally hypoallergenic and thermal regulating, incredibly soft, helps you sleep cooler, is moisture wicking, and resists odor and bacteria. Both Rayon or Viscose are very absorbent and take dye very easily. BedVoyage uses Fiber Reactive dye as its perfect for all natural fibers which include cotton, viscose bamboo, silk, wool and even wood and paper. The intensity of the colors can be from light pastels to very vibrant and deep colors, and are colorfast so that our linen colors stay true, wash after wash. Reactive dye molecules combine with the molecules of the fabric to create a permanent bond and become part of the fabric.
