Kern:

Rope Kern Part imagesIt is the internal fiber of the rope and 70% strength depends upon this part. 

 

 

Mantle:

  1. Types of Ropes (according to construction)

3.1          Utility Rope

3.2          Life Safety Rope

3.1          Utility Rope

This rope is made of Organic Fiber and cannot be used in life-saving activities. It is used to secure rescue equipment. It is made by connecting several fibers so its strength is in doubt. Water and other chemicals damage this very fast. The material used (Cotton, Vanilla, Jute, sisal, and all-natural fiber. These ropes cannot bear temperature.

3.2          Life Safety Rope

This rope is made of inorganic fibers. There it is a single fiber throughout the rope which enhances the strength of the rope. Polypropylene, polyester, and polyethylene material is used to make these. These are good against water, chemical, and temperature to a certain level.
