Have you ironed your uniforms or clothes?
Well, if you have done this activity, then, you might have noticed that the iron box has a knob to control the heating it produces.
Every electric iron nowadays comes up with this feature of different heating levels for different types of clothes. Do you know why?
Well, clothes are made up of long strands of fibres of different natures. It may be natural fibres such as cotton or wool or synthetic fibre like rayon or nylon. Different classes of fibres have different properties such as durability and strength to external heat and force. Hence, you need different levels of heat to iron different types of clothes.
Let’s understand more about fibres, their classifications and applications.

Long strands of various substances come together to form a structure resembling a thread in fibres. Examples of both natural and artificial fibres include silk, jute, and cotton. Fibres were created when people realised they needed to cover and protect their skin from the elements. There are numerous types of fibres. In this concept page, let's examine the differences between natural and synthetic fibres.
To envelop and safeguard our bodies, we use clothes made up of fibres. Some fibres could be stretched beyond 500% of their original length and then restored to their original state. Compared to rubber, it is more strong and more long-lasting. Natural and synthetic fibres are the two types of fibres that are separated based on their origin.
Two categories serve as the main divisions of fibres.
Natural fibres are divided further into two categories based on the source of extraction, which is
Plants are the source of plant fibres. These plant-based fibres, which are used to create fabrics, are harvested.
These are a few examples of fibres that are created with the assistance of animals.
Synthetic fibres are also referred to as man-made fibres. The majority of them are petrochemicals because they are created using materials derived from petroleum. Such materials are polymerized to create a chemical that binds two carbon atoms together. These fibres, which are used to create fabrics, can come from either natural or synthetic sources. They are made of a tiny unit or polymer, which is composed of numerous monomers that repeat. The following list includes synthetic fibres.
|Natural Fibre||Synthetic Fibre|
Q1. A substance made of thin, continuous strands is referred to as?
Solution: Fibres are long strands of compounds that are interconnected to form a thread structure. Cotton, jute, and silk are examples of natural and man-made fibres.
Q2. How many different categories are there for fibre?
Fibres are mainly divided into two categories.
Q3. Which of the following is not true about natural fibres?
Solution: Natural fibre is generally obtained from living organisms or nature. The colours of natural fibres are due to the colour of the source they are extracted from which is completely natural. The probability of containing pollutants or dust is very high. Whereas the durability of natural fibres are less than that of synthetic fibre. Hence, option B is the correct choice.
Q4. Which of the following is not an advantage of synthetic fibres?
Solution: Synthetic fibres have the following benefits: They are less expensive than natural fibres. They can support a heavy load and are strong. Synthetic fibres have a very long lifespan and are difficult to wrinkle. Hence, option D is the correct choice.
Q1. Why do parents advise us not to wear cotton clothes during the rainy season?
Answer: Cotton fibres are natural fibres, they absorb moisture very quickly but do not evaporate moisture easily. During the rainy season moisture content of the air is very high. Hence, it is advised to wear synthetic fibre clothes rather than cotton clothes.
Q2. Why silk clothes are very expensive?
Answer: Due to its labour- and land-intensive manufacture, silk is exceedingly expensive. It is constructed of triangular protein fibres that reflect light-like prisms.
Q3 Which is the most commonly used fibre in the world?
Answer: The most popular natural fibre in the world and still the unquestioned "monarch" of the global textile business is cotton.
Q4. Why it is advised to clean glasses with microfibres?
Answer: The safest clothes for cleaning glasses are really rare. Even seemingly soft materials, like your favourite t-shirt, can over time harm lenses due to tiny damage. Your greatest option for cleaning and drying that is both efficient and damage-free is a microfiber cloth. It is a fabric composed of millions of microscopic strands that are up to 100 times smaller than human hair and manufactured from ultra-fine synthetic yarns. A microfibre cloth can hold seven times its weight in the water thanks to the large surface area it gains from this.
