BAMBOO A GREEN FIBRE

Bhawana Rawat, Assistant Professor, NIFT, Mumbai Bamboo fibre is a cellulose fibre which is extracted from naturally grown bamboo and is the fifth-largest natural fibre after cotton, linen, wool and silk. Bamboo fibre not only has good air permeability, water absorption, strong wear-resistance and good dyeing and other features, but also has natural antibacterial, antimicrobial, mites, anti-odor and anti-ultraviolet. Bamboo fibre is a natural, environment friendly green fibre. HISTORY OF BAMBOO FIBRE The use of bamboo goes back a long time. In fact, bamboo has been considered to be a symbol of good fortune in Asian cultures for over 4,000 years. Historically in Asia, bamboo was used for the handmade production of paper. Bamboo has traditionally been used in China to make musical instruments, drinking cups, buckets, fishing rods, walls and structural posts, wicker furniture, rafts, carpets and even phonograph needles. Many of these bamboo components are still being used today.

EXTRACTION OF BAMBOO FIBRE Two types of processing are done to obtain bamboo fibres- Mechanical Processing and Chemical Processing. In both the processes, the raw bamboo has to be split to get bamboo strips. After that, bamboo fibre is extracted either through chemical or mechanical processing. 타Chemical Processing: It is basically a hydrolysis alkalization process. The crushed bamboo is "cooked" with the help of Sodium hydroxide (NaOH) which is also known as caustic soda or lye into a form of regenerated cellulose fibre. Hydrolysis alkalization is then done through carbon disulfide combined with multi-phase bleaching. Although chemical processing is not environmental friendly but it is preferred by many manufacturers as it is a less time consuming process. 타Mechanical Processing: In this method, the crushed bamboo is treated with biological enzymes. This breaks the bamboo into a mushy mass and individual fibres are then combed out. Although expensive, this process is eco-friendly.
