Bamboo is one of the fastest growing plants and India has abundant bamboo resources. Bamboo fiber can be extracted through natural or regenerated processes. There are two main methods to produce bamboo fiber - through physical and chemical treatment of the natural bast fiber or through retting and spinning of regenerated pulp fiber. The mechanical production procedure involves treating cut bamboo with enzymes to extract individual fibers which are then spun into yarn. The chemical production is similar to viscose manufacturing using solvents to remove lignin and hemicellulose. Bamboo fiber has properties of being biodegradable, breathable, antibacterial and can be blended with other fibers to produce various textile and medical products.

BAMBOO FABRIC PRODUCTION
ASSIGNMENT 1 A LITTLE ABOUT BAMBOO Bamboo is fastest growing woody plant on this planet. Sometimes the growth of bamboo is approximately three feet over a night. India has one of the richest bamboo resources in the world, second to China in Bamboo production. The numbers of species of bamboo existing in India are approximately 130. Bamboos are plants of global interest because of their distinctive life form, their ecological importance and the wide range of uses and values they have for humans. Bamboo and its related industries already provide income, food and housing to over 2.2 billion people worldwide. BAMBOO FIBER Bamboo fiber can be of two types: natural fiber(produced from the bast /phloem) or regenerated fiber (produced from the pulp). As a natural cellulosic fiber, it can be 100% biodegraded in soil by microorganisms and sunshine. Its decomposition process doesn't cause any pollution in the environment. For textile applications, bamboo fibers are mostly produced from the tallest bamboo species Phyllostachys edulis which is more popularly known as Moso. Physical and chemical properties of bamboo fiber is very close to that of viscose. EXTRACTION OF BAMBOO FIBER The characteristics displayed by the bamboo products primarily rely on whether the bamboo fiber is of natural origin or a regenerated variety. Broadly speaking, there are two main modes of effective utilization of bamboos in the textile industry : Producing natural (bast) fiber via physical and chemical treatment Spinning regenerated (pulp) fiber via retting bamboo plant into pulp
The former method gives bundles of original or pure bamboo
fibers of 2 mm staple length, whereas the latter gives bamboo viscose filaments (also called regenerated bamboo MECHANICAL PRODUCTION PROCEDURE The initially cut and crushed woody parts of the bamboo are treated with natural enzymes that break the bamboo into a soft, mushy and spongy mass. Subsequently, the natural fibers can be combed out mechanically to get individual fibers, followed by spinning yarn out of them. The fabric manufactured via this process is often termed as bamboo linen. Yao and Zhang (2011) have reported that fibers obtained are rough in texture if the sequence of operations is: cutting, separation, boiling and fermentation with enzymes. To obtain fine fibers, one should opt for the sequence: boiling, fermentation, washing and bleaching, oil-soaking and air-drying. MECHANICAL PRODUCTION PROCEDURE
From left to right, (1)bamboo is gathered ; (2) bamboo is crushed and
processes into thick mushy pulp ; (3) bamboo is further processed into fine pulp sheet ; (4) bamboo pulp manufactured into fiber through wet spinning process ; (5) bamboo fibers are spun into yarn. CHEMICAL PRODUCTION PROCEDURE When it is required to have a regenerated bamboo viscose fiber for the end-use application, the moso bamboo stalks ought to be freed from lignin and hemicellulose. The basic idea is to cook the leaves and woody shoots of the bamboo plant in these strong chemical solvents and then perform alkaline hydrolysis combined with multi-phase bleaching. The process is like conventional viscose manufacturing process; and even the product obtained is similar to rayon or modal. This regenerated cellulosic form of bamboo was first introduced by Hebei Jigao Chemical Fibre Co. Ltd, China in 2002, though its origin dates back to 1864 when it was patented by Lichtenstadt. The details of the most common process sequence are depicted through a flow chart shown next. CHEMICAL PRODUCTION PROCEDURE PROPERTIES Biodegradable Breathable (because of its structure being Anti-bacterial filled with micro-gaps Anti-static and holes) UV Protective Can be worn in both summers and winters Soft and lustrous Highly absorbent Strong, durable (more than cotton) and flexible Basic round structure Can be easily ensures it to sit blended with other perfectly next to the fibers skin.
