Question

Which one of the following is a natural fibre?
(A) Nylon
(B) Jute
(C) Acrylic
(D) Polythene

Answer 1

Hint:
 Non-woven raw material is obtained directly from an animal, vegetable, or mineral source and is converted into non-woven fabrics such as felt or paper or, after spinning, into a woven fabric. Natural fiber can be further defined as the fusion of cells where size is insignificant compared to length.

Complete step by step solution:
 Jute is the most important metal in India, found in the inner bark of two important species, Corchorus Capsularis (white jute) and Corchorus Olitorius (tossa jute). Jute is a long, soft, shiny fiber that can be spun into strong, strong fibers. It is mainly produced from plants of the genus Corchorus, once separated from the Tiliaceae family. The main source of fiber is Corchorus olitorius, but it is considered inferior to Corchorus capsularis. Jute is the name of a plant or fiber used to make burlap, hessian or gun cloth. Jute is one of the cheapest natural fibers, and the second is the only cotton in its production and various uses. Jute fibers are made mainly of plant material from cellulose and lignin. It falls into the category of bast fiber and kenaf, industrial hemp, flax (linen), ramie, etc. The industrial name for jute fiber is raw jute fiber. Jute is also called "gold fiber" for its color and high value.

Hence, the correct answer is option B.

Note:
The use of natural fibers in textile materials dates back to pre-recorded history. An old indicator of the use of fiber is probably the discovery of flax and wool fabrics in the excavations of people living in the Swiss lake. Several vegetable fibers were also used by prehistoric people. Hemp, probably the oldest fiber-growing plant, originated in Southeast Asia, and spread to China.
