Question

What are blended fibre? Give any two examples.

Answer 1

Hint: Blended fibres are made by combining the fibres. This enhances the property of the product. For example, cotton and spandex are used for sports clothing and undergarments. It improves the stretching properties of the material and prevents odour. Blended fabric improves the disadvantages of natural and synthetic fibre.

Complete step by step answer:
The polymers which have strong intermolecular forces between the chains are called the fibres. Because of strong forces, the chains are closely packed and thus, impart crystalline nature. As a result, the polymers have high tensile strength and less elasticity. These are long, thin, and thread-like and can be woven in fabrics. Therefore, these are used for making fibres. The common examples are cotton, nylon-66, Terylene, silk, etc.
The various natural and synthetic fabrics offer a wide selection of fabric for different uses. But not all fabrics are perfect in some way. They possess some good and poor properties.
Therefore, they are mixed to improve their properties. The fibre which are made by combining the different fibres to produce an improved fibre with enhanced properties are called the blended fiber.They have the combined properties of each component used for blending. The blending improves the ability of the fabric to retain the shape and gives a superior appearance. The blend of wool and cotton has the wrinkle resistance of wool and softness from the cotton.
Some of the advantages of blended fibres are as follows:
- Blending improves the colour, texture, elasticity, and even the tensile strength of the material
-It improves the appearance of the material
-the fabric can be easily dyed
-The blending increases the durability and resistance towards the washing, heat, etc.
-The blending improves the profitability of a fabric. They are cheaper compared to pure fibres.
Some of the examples of blended fibres are:
- Polly – wool is a blend of wool and polyester
-Terrycot is a blended fabric made by Terylene and cotton

Note: Do not get confused between synthetic and blended fibres. The blended fibres are advantageous over the synthetic and natural fibres. They have the properties of both. This improves properties and makes it suitable for day to day needs of buyers. For example, we use wool in winters, but the blended fibre terewool gives the wool strength and the shiny look. Remember the example of blended fibres.
