What is bamboo fiber?

Bamboo fiber is a kind of cellulose fiber extracted from natural bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has good gas permeability, instant water absorption, strong abrasion resistance and good dyeing properties, and at the same time has natural antibacterial, antibacterial, antimony, deodorant and anti-ultraviolet functions. Experts pointed out that bamboo fiber is a natural environmentally friendly green fiber in the true sense. Bamboo fiber textiles are favored by consumers because they completely replicate the inherent characteristics of bamboo fiber, and the demand for products has increased year by year.

The chemical constituents of bamboo fibrils are mainly cellulose, hemicellulose and lignin. The three are homopolysaccharides, and the total amount is more than 90% of the fiber dry mass, followed by protein, fat, pectin, tannin, pigment, Most of the ash, etc., are present in the cell lumen or in special organelles, directly or indirectly involved in their physiological effects.

Cellulose is the main substance that makes up bamboo fibril cells, and it is also the meaning of it as a textile fiber. Due to the difference in bamboo age, the cellulose content is also different, such as 75% for bamboo and bamboo, 66% for 1 year, and 58% for 3 years. The hemicellulose content in bamboo fibrils is generally 14% to 25%, and the average content of bamboo is about 22.7%, and its content also decreases with the increase of bamboo age, such as 24.9% of bamboo grown in 2 years. 4 years old, 23.6%.

Structural form of bamboo fibrils

Observed by scanning electron microscopy, the bamboo fibrils have transverse sections in the longitudinal direction, the thickness distribution is very uneven, and there are numerous fine grooves on the fiber surface. The transverse direction is irregular elliptical shape, waist round shape, etc. (Fig. 1), which has a middle cavity. The cross section is covered with large and small gaps, and the edges are cracked, which is similar to the cross section of ramie fiber. These voids, grooves and cracks in bamboo fibrils,

Like a capillary tube, it can absorb and evaporate water in an instant, so it is praised by experts as “breathing fiber”. The clothing and apparel products made from this natural bamboo fiber fiber are processed into fabrics and processed to have strong moisture absorption and good air permeability. Have a cool feeling.
