Fibres are the basic units that are used to make various textile materials such as fabrics, yarns, and threads. When fibres are twisted together to form a continuous strand, it is called spinning. The process of spinning involves twisting the fibres together to create a strong and durable thread or yarn.

Yarn is the correct answer to the question because it is the product formed when fibres are twisted by spinning. Yarn is a long, continuous strand of fibers that is used to make fabrics, textiles, and garments. It is made by twisting together individual fibres in a process called spinning.

Spinning:

- Spinning is a process in which fibres are twisted together to form a continuous strand of yarn. This can be done by hand or using machines called spinning wheels or spinning frames.
- The fibres used for spinning can be natural fibres, such as cotton, wool, or silk, or synthetic fibres, such as polyester or nylon.
- During the spinning process, the fibres are drafted, which means they are pulled out and elongated to align them in the same direction. This helps to create a smooth and even yarn.
- The drafted fibres are then twisted together using a spinning wheel or machine. The amount of twist applied to the fibres determines the strength, texture, and appearance of the yarn.
- Once the fibres are twisted together, they form a continuous strand of yarn. This yarn can then be used for various purposes, such as knitting, weaving, or sewing.

Importance of Yarn:

- Yarn is an essential component in the textile industry. It is used to create fabrics, textiles, and garments.
- Yarn provides strength and structure to the fabric. It is the foundation on which the fabric is built.
- Different types of yarns can be used to create different types of fabrics. For example, a tightly twisted yarn can be used to create a strong and durable fabric, while a loosely twisted yarn can be used to create a soft and lightweight fabric.
- Yarn can also be dyed, printed, or treated with various finishes to add color, patterns, or special properties to the fabric.
- Yarn is also used for various other purposes, such as embroidery, braiding, and crafting.

In conclusion, when fibres are twisted together through the process of spinning, they form a continuous strand called yarn. Yarn is an essential component in the textile industry and is used to create fabrics, textiles, and garments. It provides strength, structure, and versatility to the final product.
