Fibers for commercial and domestic use are broadly classified as natural or synthetic. The natural fibers are vegetable, animal, or mineral ia origin. Vegetable fibers, as the name implies, are derived from plants. The principal chemical component ia plants is cellulose, and therefore they are also referred to as ceUulosic fibers. The fibers are usually bound by a natural phenoHc polymer, lignin, which also is frequentiy present ia the cell wall of the fiber thus vegetable fibers are also often referred to as lignocellulosic fibers, except for cotton which does not contain lignin. 

Vegetable fibers are classified according to their source ia plants as follows (/) the bast or stem fibers, which form the fibrous bundles ia the inner bark (phloem or bast) of the plant stems, are often referred to as soft fibers for textile use (2) the leaf fibers, which mn lengthwise through the leaves of monocotyledonous plants, are also referred to as hard fibers and (J) the seed-hair fibers, the source of cotton (qv), are the most important vegetable fiber. There are over 250,000 species of higher plants however, only a very limited number of species have been exploited for commercial uses (less than 0.1%). The commercially important fibers are given ia Table 1 (1,2). 

The microfibrils iu vegetable fibers are spiral and parallel to one another iu the cell wall. The spiral angles iu flax, hemp, ramie, and other bast fibers are lower than cotton, which accounts for the low extensibiUty of bast fibers. 

The largest use of zinc chloride in the United States is in wood preservation, fluxes, and batteries (see Batteries). Zinc chloride solution dissolves vegetable fiber and is widely used in mercerizing cotton (qv), swelling fibers, as a mordant in dyeing, parchmentizing paper, etc (see Fibers, vegetable ... 

Paper and board are composed of cellulose obtained by the mechanical or semi-chemical treatment of vegetable fibers (pulp) derived from various sources like wood, hemp, cotton, etc. In some cases waste and regenerated paper is used.

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. 

Cellulose is the structural compound of plant cells and is very common in nature. It is found in plant material usually mixed with other polysaccharides and with lignin, resins, fats, and inorganic substances. However, several vegetal fibers such as cotton or flax contain fairly pure cellulose. Pure cellulose (microcrystalline) obtained by the purification of natural cellulose is also readily available. Although cellulose can be obtained with high purity, the quality of the material may vary depending on the degree of polymerization (DP), moisture content, etc. 

Some of the other important vegetable fibers include flax, jute, kenaf, hemp, sisal, coir, banana and pineapple. Generally, in vegetable fibers such as cotton and flax,... 

Specific Fibers. Literature on specific fibers is subdivided into the following classes cotton, wool and hair, silk, and the long vegetable fibers, with jute, flax and linen, hemp, ramie, and kenaf as constituents of the last class.

The animal fibers combine with most of the organic dyes. Cotton and other vegetable fibers cannot, in general, be dyed directly with the organic coloring matters except with certain so-called sulphur colors or with dyes derived from benzidine. Mercerized cotton, cellulose nitrates, and cellulose acetates can be dyed by substances which do not affect unaltered cellulose. 

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.
