Nylon is the first fully-synthetic fibre that was made using no natural materials. It is one of the most common synthetic fibres in use today. Nylon possesses many properties that make it a very useful fibres in many applications. It is very strong and elastic, easy to wash, and can usually be washed with similar items and does not typically require specialty laundering arrangements. Read the passage and try to answer the questions below.
Explain why nylon is called first fully-synthetic fibre?

Explanation

**Step-by-Step Solution:**

1. **Definition of Synthetic Fibres**: Synthetic fibres are man-made fibres that are created through chemical processes, rather than being derived from natural sources like plants or animals.

2. **Origin of Nylon**: Nylon was first developed in the 1930s by Wallace Carothers and his team at DuPont. It was created entirely from petrochemicals, which are derived from crude oil.

3. **No Natural Materials**: Unlike other fibres such as cotton (which comes from cotton plants) or wool (which comes from sheep), nylon does not use any natural materials in its production. This means that all of its components are synthesized through chemical reactions.
