Clothes - How Things are Made
The chapter 'Clothes - How Things are Made' in the Class 5 EVS textbook 'Our Wondrous World' for Bihar (BSEB) students explores the fascinating journey of how raw materials are transformed into the clothes we wear every day. Students will learn about natural fibers like cotton, wool, and silk, and synthetic fibers like nylon and polyester. The chapter details the step-by-step process of cloth making—from harvesting or shearing, spinning yarn, weaving or knitting fabric, to dyeing and stitching. Understanding this process builds environmental awareness and helps students appreciate the hard work of farmers, weavers, and tailors.

Natural Fibers
Threads obtained directly from plants (like cotton and jute) and animals (like wool and silk) that are used to make breathable and comfortable fabrics.
Synthetic Fibers
Man-made fibers created in factories using chemicals (like polyester, nylon, and acrylic) that dry quickly and do not wrinkle easily.
Spinning
The process of drawing out and twisting fibers together to form strong yarns or threads, traditionally done using a charkha.
Weaving and Knitting
Weaving involves interlocking two sets of yarn at right angles using a loom, while knitting uses a single continuous yarn to make loops, commonly used for woolens.
Dyeing and Tailoring
Adding vibrant colors to plain fabrics and cutting and stitching them into various garments like shirts, trousers, and frocks.

Frequently Asked Questions
What is the difference between natural and synthetic fibers?
Natural fibers are obtained from plants and animals (e.g., cotton, wool), whereas synthetic fibers are made by humans using chemicals in factories (e.g., nylon, polyester).
How is cotton converted into a shirt?
Cotton is harvested from cotton bolls, spun into yarn, woven into fabric, dyed with colors, and finally cut and stitched by a tailor into a shirt.
Why do we wear woolen clothes in winter?
Woolen fibers trap air between them, which acts as an insulator and keeps our body warm by preventing body heat from escaping.
