What are Elastomeric Fibres?

Apart from the fibres mentioned so far, there are a few less known ones. These are elastic, rubbers like substances and can be produced in various forms.

Detailed Explanation

Elastomeric fibres are special types of fibres that have elastic properties, which means they can stretch and then return to their original shape. They resemble rubber-like substances and can be produced in various forms, making them versatile in their applications.

Examples & Analogies

Think of a rubber band. When you stretch it, it expands, and when you let go, it snaps back to its original size. Similar to this, elastomeric fibres can stretch and then return to their initial shape, which makes them very useful in clothing and textiles, particularly for items requiring comfort and flexibility, like sportswear or fitted clothing.

Natural and Synthetic Elastomeric Fibres

In its natural form they include rubber and the synthetic equivalent is spandex or Lycra.

Detailed Explanation

Elastomeric fibres can be derived from natural sources or can be synthetically produced. Natural elastomeric fibres include rubber, which is harvested from rubber trees. On the other hand, synthetic elastomeric fibres, such as spandex or Lycra, are chemically manufactured to achieve similar elastic properties. Spandex is widely known for its use in form-fitting textiles.

Examples & Analogies

Imagine the difference between natural and artificial sweeteners. Just like both can provide sweetness but come from different origins, rubber comes from trees while spandex is created in a lab. Both types have their unique uses—rubber for tires and spandex for workout clothes—showing how material source affects application.

Applications of Elastomeric Fibres

These are usually used as blends with any of the above fibres with low elasticity.

Detailed Explanation

Elastomeric fibres are often blended with other types of fibres to enhance their elasticity. For instance, a fabric made purely from cotton might lack the stretch required for comfortable activewear. By blending elastomeric fibres like spandex with cotton, manufacturers can create fabric that retains the soft feel of cotton but adds the flexibility needed for movement.

Examples & Analogies

Think about a yoga class. If everyone wore rigid jeans, it would be hard to stretch and move. However, if they wore yoga pants made of a cotton-spandex blend, they'd be comfortable and flexible. This blend allows for better movement, just as elastomeric fibres do in clothing.

Importance of Understanding Elastomeric Fibres

Having studied about fabrics in this chapter, you will be introduced to the world of apparel, i.e., clothes, made from fabrics later under the section ‘Childhood’. Knowing about fabrics is important for the adolescent as it would enable one to make wise selection of clothes.

Detailed Explanation

Understanding elastomeric fibres is essential for adolescents as it aids them in making informed choices about their clothing. Knowing which fabrics contain elastomeric fibres helps them select clothing that is comfortable and suitable for various activities, such as sports or casual wear.

Examples & Analogies

When adolescents choose clothes, it's like picking a tool for a job. If they know that a fabric made with elastomeric fibres is great for sports, they can make a smarter choice that enhances their performance and comfort. Just as a chef needs the right knife, students need to know the right fabric for their lifestyle.
