6.Boojho went to a cloth shop. There he found a fabric which was smooth to touch, and had vibrant colour and shine. The fabric could be

(a) cotton

(b) wool

(c) silk

(d) jute


Explanation:


The correct option is
(c) Silk


The fabric that Boojho found in the cloth shop which was smooth to touch and had vibrant colour and shine is likely to be silk.

Silk is a natural fiber produced from the cocoons of silkworms and is known for its softness, smoothness, and shine. Cotton is soft and breathable, but it is not very shiny. Wool is warm and soft, but it is not typically shiny. Jute is a plant fiber and has a rougher texture, and it is not typically used to make fabrics with a smooth texture or shine.


7.Which part of the jute plant is used for getting jute fibre?

(a) Flower

(b) Stem

(c) Fruit

(d) Leaf

Explanation:



The correct option is (b) Stem

The jute fiber is obtained from the stem of the jute plant. The long, soft, and shiny fibers are found beneath the bark, which are separated from the non-fibrous matter by retting. The jute fibers are then washed, dried, and sorted to obtain the final fiber that is used for making a variety of products such as ropes, twine, bags, mats, and carpets, among others.


8.Yarn is woven to get fabric using

(a) charkha

(b) spinning machines

(c) looms

(d) knitting needles

Explanation:


The correct option is
(c) looms

Yarn is woven to get fabric using looms. A loom is a device used to weave yarn into fabric. The process of weaving involves interlacing two sets of yarns at right angles to each other to form a fabric. The longitudinal yarns are called the warp, and the transverse yarns are called the weft. The loom holds the warp yarns under tension while the weft yarn is woven back and forth through the warp. There are different types of looms, including hand-operated looms, power looms, and automated looms.


9.Beera is a farmer. His field has black soil, and the climate is warm. Which fibre-yielding plant should he grow in his field?

(a) Jute

(b) Cotton

(c) Coconut

(d) Wool

Explanation:


The correct option is
(b) Cotton


Beera, with a field that has black soil and a warm climate, should grow cotton in his field. Cotton requires well-drained, fertile soil and a warm climate to grow. The black soil is ideal for cotton cultivation, as it retains moisture well and is rich in nutrients. Jute, on the other hand, requires soil that is low in fertility and more acidic. Coconut is a tree crop, and wool comes from sheep or other animals, which are not suitable for farming in Beera's field.

10.The correct sequence to get cloth is

(a) fibre → fabric → yarn

(b) fibre → yarn → fabric

(c) fabric → yarn → fibre

(d) yarn → fibre → fabric

Explanation:


The correct option is
(b) fibre → yarn → fabric.


First, fibres are obtained from sources such as cotton, jute, wool, or silk. These fibres are then spun into yarns using spinning machines or charkhas. Finally, the yarns are woven into fabrics using looms. So, the correct sequence is: fibre → yarn → fabric.


11.Boojho wants to make yarn from the fibre at home. Which of the following will he use to carry out the task?

(a) Powerloom

(b) Handloom

(c) Charkha

(d) Knitting needles

Explanation:


The correct option is
(c) Charkha


Charkha is a hand-operated spinning wheel used for spinning cotton, silk or other fibers into yarn. It is a traditional tool used in the Indian subcontinent and was popularized by Mahatma Gandhi as a part of the Indian independence movement. The charkha is a portable device that can be easily carried and operated, making it ideal for use in rural areas. It works by twisting fibers together using a spindle and a flyer, which are operated by hand.

16.Once, Paheli visited a tailor shop and brought home some cuttings of fabric to study their properties. She took two pieces and found that one of the pieces was shrinking when it was burnt with a candle. However, the other did not shrink on burning. Can you help her to find out which of the two was a cotton fabric and which was a silk fabric?


Explanation:


Yes, I can help Paheli to find out which of the two fabrics was cotton and which was silk.

The fabric that shrinks on burning is a Silk. Silk is a synthetic fibre that shrinks on burning, while cotton does not shrink on burning.

When silk is burned, it gives off a smell similar to burning hair, and the ash produced is black and brittle. Cotton, on the other hand, burns quickly, giving off a smell similar to burning paper, and leaves behind a soft and feathery ash.

Therefore, the fabric that shrinks on burning is silk, and the other fabric is cotton.


17.One way of making fabric from yarn is weaving, what is the other?


Explanation:


The other common method of making fabric from yarn is
knitting.

Knitting involves interlocking loops of yarn to create a fabric. Unlike weaving, where the yarns are arranged perpendicular to each other, in knitting, the yarns run parallel to each other. Knitting can be done by hand or by machine, and it can produce a variety of fabric types, including fine, stretchy fabrics for clothing and thicker, more structured fabrics for items like blankets and upholstery.

18.Boojho, with perfect eyesight, was finding it difficult to pass a thread through the eye of a needle. What can be the possible reason for this?

Explanation:


If the needle and thread size are not matched properly, it can be challenging to pass the thread through the needle. For example, if the thread is too thick for the needle
or the needle's eye is too small, it can be difficult to pass the thread through.

Or if the end of the thread is split or separated into multiple strands then it can be difficult to pass the thread through the needle’s eye.

19.In ancient times, stitching was not known. People used to simply drape the fabrics around different parts of their body. Even today a number of unstitched fabrics are used by both men and women. Can you give four such examples of clothes?


Explanation:


Here are four examples of unstitched fabrics used by both men and women:


  1. Saree: The saree is a long piece of unstitched fabric that is draped around the body, with one end wrapped around the waist and the other draped over the shoulder. It is commonly worn by women in South Asia, particularly in India, Pakistan, Bangladesh, and Sri Lanka.


  1. Lungi: The lungi is a rectangular piece of cloth that is worn around the waist and legs, similar to a sarong. It is commonly worn by men in South and Southeast Asia, particularly in India, Bangladesh, Pakistan, and Sri Lanka.


  1. Kikoi: The kikoi is a rectangular piece of cloth that is worn by both men and women in East Africa. It is similar to a sarong and is typically worn around the waist.


  1. Thawb: The thawb is a long, loose-fitting robe-like garment that is commonly worn by men in the Middle East and North Africa. It is typically made from lightweight, breathable fabric and can be worn for both formal and informal occasions.

Some other useful items made from jute fibres are:


24.A cotton shirt, before it reaches you, completes a long journey. Elaborate on this journey, starting from cotton bolls.

Explanation:


Here's the journey of a cotton shirt, starting from cotton bolls:


  1. Harvesting: Once the cotton plants mature, the cotton bolls are picked by hand or with machines. These bolls contain seeds and cotton fibres.


  1. Ginning: The cotton fibres are then separated from the seeds in a process called ginning. This can be done using machines or by hand.


  1. Spinning: The separated cotton fibres are then spun into yarns using spinning machines. The yarns can be of different thicknesses depending on the desired fabric.


  1. Weaving or Knitting: The yarns are then woven or knitted into fabrics using machines or by hand. This step involves arranging two sets of yarns together to create a fabric.


  1. Dyeing and Printing: The fabrics may then be dyed to add colour and patterns using various techniques. This can be done before or after the fabric is made into a garment.


  1. Manufacturing: The fabrics are then sent to garment manufacturers who cut and sew the fabric into various garments, including shirts.


  1. Distribution: The finished garments are then packaged, labeled, and shipped to retailers, where customers can purchase them.


  1. Purchase: The cotton shirt is then purchased by the customer and becomes a part of their wardrobe.

25.Describe the two main processes of making fabric from yarn.


Explanation:


The two main processes of making fabric from yarn are:


  1. Weaving: Weaving is the process of interlacing two sets of yarns, the warp yarns and the weft yarns, at right angles to each other to create a fabric. The warp yarns are arranged lengthwise on a loom, while the weft yarns are woven across the warp yarns using a shuttle or other devices. The process of weaving can create a variety of fabrics, from lightweight, sheer fabrics to heavy, sturdy ones.


  1. Knitting: Knitting is the process of creating a fabric by interlocking loops of yarn. Unlike weaving, knitting uses a single set of yarn, which is manipulated using knitting needles or a knitting machine to create loops that are interlocked with each other. The process of knitting can create a variety of fabrics, including lightweight, stretchy fabrics like t-shirts or thicker, insulating fabrics like sweaters.


Both weaving and knitting have their own unique characteristics and advantages. Weaving is generally faster than knitting and can produce larger quantities of fabric at a time, making it a popular choice for industrial fabric production. Knitting, on the other hand, is more flexible and can create more complex shapes and patterns. It is often used to make items like socks, gloves, and other clothing accessories that require a close fit.
