Vegetable fibers kapok

The principal bast and leaf fibers are produced in yields of 2-5%. with some exceptions such as flax (I Slid and kapok 11 7%). on a green plant basis. Vegetable fiber production on lire world market has dropped 25-3.VJ1 since 1970 because of periods of economic recession and synthetic fiber replacements. Imports of vegetable fibers have dropped 70-90% since... 

The first category of vegetable fiber is of seed-hair fibers, which includes cotton, kapok, flosses obtained from seeds, seedpods, and the inner walls of fruit. 

Fiber, vegetable Different vegetable fibers are used in RPs, etc. They include (1) seed-hair-cotton, kapok, milkweed floss (2) bast-flax, hemp, jute, ramie and (3) leaf-abaca, sisal. 

It has been mentioned earlier that vegetable fibers other than cotton and kapok are multicellular. The mechanical properties of these fibers, therefore, reflect an interaction between their ultimates and their middle lamella substances ramie is an exception because the size of its ultimates is large enough to act as a fiber. 

Only the vegetable fibers section with kapok, ramie, flax, hemp, jute, sisal, and coir is anticipated to have stagnated at 5.9 million tonnes.

Vegetable fiber n. A textile fiber of vegetable origin, such as cotton, kapok, jute, ramie, and flax. Wallenberger ET, Weston NE (eds) (2003) Natural fibers, plastics and composites. Springer-Verlag, New York. Kadolph SJJ, Langford AL (2001) Textiles. Pearson Education, New York. 

Synthetic material polyurethane foam is a much better sorbent than agriculture products and has proven to have the overall highest sorption capacity 100 times its weight. However, the natural materials mentioned above (such as straw. Kapok, vegetables fibers, peat, or bark) are more readily available at much lower costs and biodegradable.
