Select the correct increasing order of the tensile strength of the given fibres.

 

Tensile strength is an important property of fibers that refers to their ability to resist breaking or tearing when subjected to tension or stretching forces. The tensile strength of a fiber depends on its composition, structure, and processing methods.

In the given options, the correct order of increasing tensile strength of fibers is Wool < Cotton < Nylon < Polyester.

Wool is a natural protein fiber and has a relatively low tensile strength compared to other fibers. Its smooth surface structure makes it easy to break when stretched.

Cotton, another natural fiber, has a slightly higher tensile strength than wool but is still relatively weak compared to synthetic fibers.

Nylon is a synthetic fiber that has a higher tensile strength than wool and cotton. Its strong molecular structure makes it resistant to stretching and breaking.

Polyester, also a synthetic fiber, has the highest tensile strength among the given fibers. It is known for its exceptional strength and durability, making it a popular choice for high-performance textiles.

In summary, the correct order of increasing tensile strength for the given fibers is Wool < Cotton < Nylon < Polyester
