Step 1: Understanding the Concept:
The question asks for the most fundamental component used to create fabric. The production of textiles follows a specific hierarchy from the smallest element to the final product.
Step 2: Detailed Explanation:
The process of creating fabric starts with the smallest element and builds up:
1. Fibre: This is the basic raw material, a fine, hair-like strand. Examples include cotton, wool (natural fibres), and polyester (synthetic fibre).
2. Yarn/Thread: Fibres are twisted or spun together to form a continuous strand called yarn (or thread).
3. Fabric: Yarn or thread is then woven, knitted, or felted together to create a flat sheet of material, which is the fabric.
Therefore, the fibre is the most basic, indivisible unit from which fabric is ultimately made.
Step 3: Final Answer:
The basic unit of fabric is the fibre.
