outer covering of coconut is hard give reason
Answers
Explanation:
The outer fibrous covering of coconut make up the husk of coconut. They are made up of fibres called coir. Coir fibre is waterproof and resistant to damage.
Answer:Coconut fiber, obtained from unripe coconut, is a natural fiber extracted from the husk of coconut. The coconut is steeped in hot seawater, and subsequently, the fibers are removed from the shell by combing and crushing, the same process as jute fiber. The individual fiber cells are narrow and hollow with thick walls made of cellulose, and each cell is about 1 mm long and 10–20 μm in diameter, as shown in Fig. 2.6. The raw coconut fibers show length varying from 15 to 35 cm and diameter from 50 to 300 μm. When they are immature and then become hardened and yellowed because a layer of lignin is deposited on their walls. Coconut fiber shows a good stiffness and is used in products such as floor mats, doormats, brushes, mattresses, coarse filling material, and upholstery
Explanation:Coconut fiber is the most well-known fibrous waste from the coconuts cultivation. Every year the world produces at least 30 million tons of coconut, which are abundant in coastal areas of tropical countries. The coconut husk is composed of 30% fiber and 70% pith, with high lignin and phenolic content (Panyakaew and Fotios, 2011). Due to the high lignin content, coconut fiber is very elastic, durable, and resistant to rotting. Danso (2017) measured coconut husk fibers with a mean diameter of 400 µm and mean length of 103 mm, being more resilient than oil palm bark fibers.
