Question

Which of the following fiber is used in parachute making and ropes for rope climbing?

• A. Jute
• B. Nylon
• C. Rayon
• D. Teflon

Answer 1

The correct option is B

Nylon

The correct option is B.

Explanation of correct options:

Fibers:

1. Fibers are thread-like structures with thin, lengthy, and flexible strands that can be broadly defined. Plants and animals are the two primary categories of fibers.
2. Fibers are classified into two categories,

• Natural Fibers
• Man Made Fibers.

Nylon:

1. Out of all the possibilities, Nylon is the strongest and most elastic.
2. It aids in producing the strongest ropes.
3. Because it can quickly return to its previous length after being stretched, it is typically employed for absorbing shock loads, such as towing.
4. Additionally, the abrasion resistance is strong and can last far longer than natural fibers.

Explanation of incorrect options:

Option A

1. It is the botanical name for the fiber that is used to make burlap, hessian, or gunny cloth.
2. This fiber is one of the more cheap natural fibers, and it is second only to cotton in terms of production and variety of applications.
3. Due to its lack of increased toughness, it is not used to make rope and in parachutes.

Option C

1. It is a natural substance that is derived from the cellulose present in cotton or wood pulp.
2. The cost of rayon is rather modest, and it is an incredibly practical fiber that adapts to various uses.
3. There are a few types of rayon that are used for various things, but they are not utilized to make rope or parachutes.

Option D

1. The most widely used plastic substance known by this term, is polytetrafluoroethylene (PTFE).
2. Fluoropolymers are a type of plastic that includes this one.
3. Chemical reactions that combine small molecules into repeating groups of molecules are called polymers.

Final answer: Nylon is used In parachute making and ropes for rope climbing.
