mahmud_ Fiber in Nature _02

Natural Fiber :

Bast fiber or skin fiber :
Bast fibre (fiber) or skin fibre is plant fibre collected from the phloem (the "inner bark" or the skin) or bast surrounding the stem of certain, mainly dicotyledonic, plants. They support the conductive cells of the phloem and provide strength to the stem

example 01: Jute

Brief:
Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. It is produced from plants in the genus Corchorus, family Tiliaceae.

Organizational & structural quality:
Jute fibres are composed primarily of the plant materials cellulose (major component of plant fibre) and lignin (major components wood fibre). It is thus a ligno-cellulosic fibre that is partially a textile fibre and partially wood. The fibres are off-white to brown, and 1–4 meters (3–12 feet) long.
