Bamboo textiles are typically cloths, yarn, and clothing made from Bamboo fiber. In earlier times; farmers and fisherman in China and Japan used bamboo to weave shoes and hats to protect them from the elements. In the west, bamboo was used along with whalebone and steel wire for women's corsets, bustles and other women's fashions; during the 1800's. Presently, bamboo yarn can be blended with other fibers such as cotton, hemp, and spandex.

Recently, in 2003 inventors filed for US Patent 7313906 to turn bamboo cellulose into yarn; creating new uses for bamboo in clothing and home textiles.

Listed below are the steps used to process raw bamboo into yarn for consumer products -

1). Steam is used to remove bamboo leaves and the pith from the bamboo trunk, then the leaves and pith are crushed.

2). Crushed bamboo is then soaked in *-Sodium Hydroxide to produce bamboo cellulose.

* A COMMON MISCONCEPTION is that Sodium Hydroxide is a harmful chemical. As with many chemicals, when used responsibly, Sodium Hydroxide has no effect on the environment or the health of the workers.

- Sodium Hydroxide is routinely used to PROCESS ORGANIC COTTON into fiber and is APPROVED BY THE GLOBAL ORGANIC TEXTILE STANDARDS (GOTS) AND THE SOIL ASSOCIATION. SODIUM HYDROXIDE DOES NOT REMAIN AS A RESIDUE on clothing as it is easily washed away and neutralized harmless and NON- TOXIC SODIUM SULFATE SALT.

3). Next, the bamboo cellulose is forced though nozzles, similar to a sieve, into an acid bath that hardens the solution into bamboo fiber threads and neutralizes Sodium Hydroxide.

4. The bamboo fiber is then spun into bamboo yarn and rolled onto spools.

Environmentally conscience and principled manufacturers use a closed loop system to process bamboo into yarn. The closed loop process captures and reclaims chemical solvents used in the manufacturing process. The end result is the bamboo/ viscose from bamboo is very soft to the touch.
