Let’s discuss plant fibers in detail. Various parts of plants like woody core, bast, leaf, cane, straw from cereals, grass and seed can be used in applications like building materials, particleboards, insulation boards, human food and animal feed, cosmetics, medicine and sources of other bio-polymers and "fine chemicals". Bast is the outer covering of stem in plants. The removal of the bast fibers from bark and woody stem parts is promoted by a biological treatment called retting (rotting). S3 is Z‐twist in flax, while in ramie and hemp the microfibrils in S3 are almost parallel to the fibre axis (Harris, 1954; Meredith, 1956; Lewin, 2006). The 2009 classification system of the Angiosperm Phylogeny Group (APG III) places the family Agavaceae, Ruscaceae, and others in an expanded Asparagaceae (Simpson 2010).

Plant fibres such as sisal, ramie, bamboo, kapok, pineapple, coir, hemp, jute, flax, and kenaf are generally classified by the part of the plant from which they are obtained such as leaf, seed, fruit, stem, and bast. The major issue now is the ability of textile specialists and archaeobotanists to distinguish the technology of splicing from draft-spun fibres. It supports the conductive cells of the phloem and provides strength to the stem. It has uses in agriculture and horticulture as well. A method for separating decorticated bast skin into individual fibres, comprising maintaining decorticated bast skin in a closed container in the presence of at least one enzymatic and/or chemical retting agent for a period sufficient for at least a portion of the fibre bundles to separate into individual fibres. Vegetable fibres are obtained from the various parts of the plants. Aside from these established processes, emerging enzymatic processes such as cotton scouring and bleaching, bast fiber retting/degumming, wool scouring and shrink-proofing, silk degumming, bio-dye production and enzyme-assisted dyeing and finishing are at various stages of development. Some examples of bast fibres are jute (Corchorus olitorius/ Corchorus capsularis), flax (Linum usitatissimum), abaca (Musa textilis), and kenaf (Hibiscus cannabinus).
