Which of the following material is a mixture of two fibres?

Polywool

The correct answer is option  2. Polywool.

Polywool is a textile material that is created by blending two different types of fibers: polyester and wool. Polyester is a synthetic fiber, while wool is a natural fiber obtained from the fleece of sheep or other animals. The combination of these two fibers in polywool fabric is designed to incorporate the positive characteristics of both materials. Here is a brief explanation of the properties of polyester and wool:

1. Polyester:
Durable and resistant to wrinkles and shrinking.
Quick-drying and retains its shape well.
Resistant to abrasion and easy to care for.

2. Wool:
A natural insulator, providing warmth even when wet.
Breathable and moisture-wicking.
Soft and comfortable against the skin.

By blending these fibers, polywool fabric aims to achieve a balance of characteristics. The resulting material may have improved durability, resistance to wrinkles, and ease of care due to the polyester content, along with the natural warmth and comfort of wool. This combination allows manufacturers to create textiles that offer the benefits of both synthetic and natural fibers in a single material. Polywool is commonly used in various types of clothing and textiles, providing a versatile option for different applications.
