Fibre to Fabric

Human beings' fundamental needs include food, shelter, and clothes. Let us talk about clothing and why it is significant. Clothes protect our bodies from the environment. They protect us from pest bites and enhance our appearance. People dress differently depending on where they are and what the weather is like. Clothes are created from a variety of materials. Cotton saris are made of cotton, leather jackets are made of leather, sweaters are made of wool, and so on.

People dressed in bark, leaves, and animal fur during the beginning of mankind. When humans first settled down as farmers, they wore garments made of braided vines and animal fleece. Flax and cotton were then woven into clothing in the next step. People just draped the cloth to cover themselves at the time. Only with the invention of the needle did people begin to wear sewn clothing. Even today, in ancient civilizations such as India, individuals wear unstitched clothes such as turbans, saris, and dhotis.

Fiber is a material that comes in the shape of a thin and continuous thread. Yarn is a drawn and twisted strand of fiber used to manufacture fiber. Fabrics are formed of yarns, while yarns are made of fibers. A loom is used to weave cloth out of yarn. A loom may be either a power loom or a handloom. Clothes are made from fibers. Two strands are used together, one lengthwise and the other across. Weft refers to the crosswise yarn.

In this chapter, students learn about fabrics like wool and silk – how they are made using animal fibers, the process of extraction of silk. Fibers are found in both plants and animals. Natural fibers account for more than half of all fibers produced. Cotton, hair, fur, silk, and wool are examples of natural fibers. Other fibers are produced. Manufactured fibers are classified into two types: regenerated fibers and synthetic fibers. Regenerated fibers are created by processing natural resources to build a fiber structure. Regenerated fibers, also known as cellulosics, are made from the cellulose found in cotton and wood pulp. Rayon and acetate are two of the most prevalent regenerated fibers.

Synthetic fibers are totally made of chemicals. Synthetic fibers are often more durable than natural or regenerated fibers. Thermoplastic fibers, such as synthetic fibers and regenerated acetate fibers, are softened by heat. As a result, producers may shape these fibers at high temperatures, including characteristics such as pleats and creases. If a hot iron is used on synthetic fibers, they will melt. Nylon (polyamide), polyester, acrylic, and olefin are the most common synthetic fibers.

The different types of fabrics are silk, which is a natural fiber that is created by insects as a material for nests and cocoons. Silkworms produce the most prevalent sort of silk. Silk is a material that is noted for its sheen and softness. It is formed mostly of a protein called fibroin.

Wool is a fabric made from the hair of animals such as sheep, goats, alpacas, llamas, and others. Wool materials include cashmere, angora, mohair, and others. Wool is a warm, absorbent, and long-lasting material. It is water-resistant because of the lanolin oils found in animals, and it is often used to manufacture outerwear and cold-weather clothing such as sweaters and jackets.

Cotton fabric is manufactured from plant fibers derived from the cotton plant. Cotton is a soft and fluffy substance made mostly of cellulose, an insoluble organic component essential to the plant structure. Cotton fabric is comfortable and long-lasting, and it is often used to produce t-shirts and underwear. Organic cotton, denim, and canvas are a few examples of cotton fabrics.

Linen is a durable, lightweight fabric derived from the flax plant. Linen is inherently hypoallergenic and breathable, making it an excellent fabric for summer clothing.

Jute is a coarse natural plant fiber derived from the jute plant that is used to weave garments such as burlap cloth. Jute is a popular fabric for carpets and burlap sacks.

In Chapter 3, Fiber To Fabric, Class 7 students learn about answers to questions like:

Do some of our clothes come from animal sources?

Which are these animals? 

Who rears them? 

Which parts of the animals yield the yarn? 

How is the yarn extracted? 

What kinds of clothes help us to keep warm? 

What is heat? 

What is the meaning of ‘cool’/‘cold’ and ‘warm’ ‘hot’?

Motion and Time

Motion and Time are among the most popular concepts in Physics. The concept of motion and rest only applies to objects that have mass. Motion and time are two interdependent quantities that are written out as mathematical numbers in detail. The SI unit of speed and velocity is metres per second. These concepts are very useful in day to day applications. Some of the sub-topics taught in this chapter are mentioned below.
