Staple Fibre:
Staple fibres are short fibres that are measured in inches or centimeters. They are typically less than 6 inches in length. These fibres are used to make fabrics that are soft, breathable, and comfortable to wear.

Cotton:
Cotton is a type of natural fibre that comes from the cotton plant. It is one of the most widely used fabrics in the world. Cotton fibres are staple fibres, which means they are short in length.

Nylon:
Nylon is a synthetic fabric that is made from petrochemicals. Unlike cotton, nylon is not made from staple fibres. It is made from long continuous filaments that are extruded and then twisted together to form yarn.

Polyester:
Polyester is another synthetic fabric that is made from petrochemicals. Similar to nylon, polyester is not made from staple fibres. It is made from long continuous filaments that are spun into yarn.

Silk:
Silk is a natural fabric that is made from the cocoons of silkworms. Unlike cotton, silk is not made from staple fibres. It is made from a long continuous filament that is secreted by the silkworm to form its cocoon.

Conclusion:
Out of the given options, cotton is the only fabric that is made from staple fibres. Nylon, polyester, and silk are all made from long continuous filaments. Cotton's staple fibres contribute to its softness and breathability, making it a popular choice for clothing and other textile products.
