Test: Fibre to Fabric - Class 6 MCQ

Mahatma Gandhi popularized the charkha (spinning wheel) as a part of the independence movement. He encouraged Indians to spin their own cloth, especially khadi, to promote self-reliance and reduce dependence on British-made goods. The charkha became a symbol of the Swadeshi movement and a tool for economic and political resistance against British colonial rule.

• Option A (Handloom) is related to weaving but was not specifically popularized by Gandhi.
• Option B (Shuttle) is a tool used in weaving, not directly linked to Gandhi's movement.
• Option D (Machine) is too general and does not refer to a specific device promoted by Gandhi.

Hence, the correct answer is Charkha.

Retting is the process that involves the rotting of the gummy skin of jute sticks in water. This process helps to separate the fibers from the stalks of the jute plant, making them suitable for spinning into yarn. The fibers are softened and loosened as the pectin and other substances in the stem break down during retting.

• Option A (Baling) refers to the process of compressing fibers or other materials into bales.
• Option B (Ginning) is the process of separating cotton fibers from seeds.
• Option D (Spinning) is the process of turning fibers into yarn or thread.

Therefore, the correct answer is Retting.

The two main processes of making fabrics are weaving and knitting.

• Weaving involves interlacing two sets of yarns (the warp and the weft) to create fabric. This is typically done on a loom.
• Knitting involves interlocking loops of yarn to create fabric, which is typically done using needles.
• Option A (Ginning and weaving) refers to processes in the cotton industry but not directly related to fabric production.
• Option C (Weaving and spinning) mixes fabric production (weaving) with yarn production (spinning).
• Option D (Ginning and knitting) is incorrect because ginning is related to cotton fiber processing, not fabric creation.

Therefore, the correct answer is Weaving and knitting.

Let's analyze the statements:

• Option A: "The fibres of some fabrics such as cotton, jute, silk, and wool are obtained from plants and animals. These are called synthetic fibres."
• This is incorrect because cotton and jute are natural plant fibers, and silk and wool are natural animal fibers. Synthetic fibers are man-made, such as nylon, polyester, or acrylic, not naturally occurring fibers.
• Option B: "Cotton and jute are examples of fibres obtained from animals."
• This is incorrect. Cotton and jute are both plant fibers.
• Option C: "Wool and silk fibres are obtained from plants."
• This is incorrect. Wool comes from the fleece of sheep (animal source) and silk comes from the cocoons of silkworms (also an animal source).
• Option D: "None of the above"
• This is the correct option since none of the statements A, B, or C are accurate.

Therefore, the correct answer is Option D.

The correct order of processes involved in making cotton fabric is:

1. Hand picking of cotton bolls: Cotton is harvested from cotton plants.
2. Ginning: The cotton fibers are separated from the seeds and cleaned.
3. Spinning: The cotton fibers are twisted into yarn or thread.
4. Weaving: The yarn is woven into fabric using a loom.

Option B accurately represents the correct sequence of processes.

• Option A is incorrect because knitting is not part of the typical process for cotton fabric production.
• Option C is incorrect because weaving comes after spinning, not before.
• Option D is incorrect because Ginning should happen before spinning.

Thus, the correct answer is Option B.

When fabrics or fibers are twisted before being made into yarns or threads, it makes them stronger. The twisting helps to bind the individual fibers together, improving the strength and durability of the resulting yarn or thread.

• Option A (Make them more absorbent) is not the main result of twisting fibers.
• Option C (Make them smooth) is not the main result of twisting; twisting can sometimes make the fibers less smooth, depending on the degree of twist.
• Option D (Add air spaces inside the fibers) does not directly relate to the twisting process but may occur in certain types of yarns, like those designed to be lightweight or fluffy.

Thus, the correct answer is Make them more strong.

• Option A: "Flax is a plant that gives natural fibers."
  This statement is correct. Flax is indeed a plant that produces natural fibers, which are used to make linen fabric.
• Option B: "In ancient Egypt, cotton as well as flax were cultivated near the river Nile and were used for making fabrics."
  This statement is incorrect. Cotton was not cultivated in ancient Egypt. Flax, however, was cultivated and used for making linen. Cotton cultivation became widespread in later periods.
• Option C: "In ancient times, stitching was known."
  This statement is incorrect. While ancient civilizations had some methods of fastening fabrics, stitching as we know it (sewing with a needle and thread) was not widely practiced in the earliest times. Early methods involved tying or using adhesives.

Therefore, the correct answer is Option C, as it represents the incorrect statement.

Let's analyze each option:

• Option A: "Silk, chemicals"
  Silk is a natural fiber obtained from the silk worm, and chemicals can be used to create synthetic fibers like nylon or polyester. So, both can be used in fiber production, but chemicals aren't natural fibers.

• Option B: "Yak hair, camel hair"
  Yak hair and camel hair are natural fibers obtained from animals. They are used to make fabrics, such as wool and other warm clothing materials.

• Option C: "Husk, bones"
  Husk (such as rice husk) and bones are not used for making fibers. These are by-products of agricultural processes but are not directly used to make fabrics or fibers.

• Option D: "Flax, wool"
  Flax is a plant fiber used to make linen, and wool is an animal fiber from sheep. Both are used for making fibers.

Therefore, the correct answer is Option C, as husk and bones are not used for making fibers.

The spindle works on the principle of the charkha. A spindle is a tool used to twist fibers into yarn, similar to how the charkha (spinning wheel) is used to spin fibers into yarn manually. The spindle and charkha both involve the process of spinning fibers to create thread or yarn.

• Option A (Dyeing machine) is used for coloring fabrics, not related to spinning.
• Option B (Shearing machine) is used for trimming or cutting fibers, not spinning.
• Option D (Power loom) is used for weaving fabric, not spinning fibers into yarn.

Thus, the correct answer is Spindle.

In ancient times, people used leaves of trees and animal skins and furs for making clothes.

• Leaves of trees were sometimes used for basic coverings or in regions where plant fibers were readily available.
• Animal skins and furs were commonly used for clothing, especially in colder climates, as they provided warmth and protection.
• Newspaper and metal foils are not materials used for making clothes in ancient times.

Therefore, the correct answer is Option D.
