NCERT Solutions For Class 6 Science Chapter 3 Fibre To Fabric in Hindi - 2025-26
FAQs on NCERT Solutions For Class 6 Science Chapter 3 Fibre To Fabric in Hindi - 2025-26
1. How do you solve the question in NCERT Class 6 Science Chapter 3 that asks to classify fibres as natural or synthetic?
To solve this question as per the NCERT methodology, you should classify the given fibres by identifying their source. The correct classification is:
- Natural Fibres: These are obtained from plant or animal sources. Examples are cotton (from cotton plant), jute (from jute plant), wool (from sheep), and silk (from silkworms).
- Synthetic Fibres: These are man-made using chemical processes. Examples are nylon and polyester.
The NCERT solution requires you to state the source to justify the classification.
2. What is the step-by-step process to make yarn from fibre, as explained in the NCERT solutions for Chapter 3?
The NCERT solutions explain the process of making yarn from fibres, known as spinning. The steps are:
- First, a mass of fibres (like cotton wool) is drawn out.
- Next, these drawn-out fibres are twisted together.
- This twisting action brings the thin fibres together to form a strong, continuous thread called yarn.
Simple devices like a hand spindle (takli) or a spinning wheel (charkha) are used to perform this process.
3. How are the NCERT Solutions for Class 6 Science Chapter 3 structured to help with exam preparation for the 2025-26 session?
The NCERT Solutions for Class 6 Science Chapter 3 are structured to provide complete and accurate answers for all textbook exercises, aligning with the CBSE 2025-26 syllabus. They cover various question types, including fill-in-the-blanks, true/false, classification, and descriptive answers. Each solution is explained clearly, helping students understand the correct method and keywords needed to score well in exams.
4. Why is ginning an essential first step for cotton fibres before they can be spun into yarn?
Ginning is essential because cotton fibres are harvested along with their seeds. The process of ginning is specifically designed to separate the fibres from the seeds. If the seeds were left in, it would be impossible to spin a smooth, strong yarn. The seeds would create lumps, weaken the yarn, and make it unsuitable for making fabric. Therefore, ginning is a crucial cleaning and preparation step.
5. What is the fundamental difference between the weaving and knitting processes used to make fabric?
The fundamental difference lies in the number of yarns used and how they are interlinked:
- Weaving: This process uses two sets of yarns arranged together at right angles to each other on a machine called a loom. It typically produces a firm and less-stretchy fabric like that used for shirts or bedsheets.
- Knitting: This process uses a single continuous yarn to form interlocking loops. This method creates a more flexible and stretchable fabric, such as that used for sweaters, socks, and T-shirts.
6. According to the NCERT Solutions, what are the two main processes for converting yarn into fabric?
The two main processes detailed in the NCERT solutions for converting yarn into fabric are weaving and knitting. Weaving involves interlacing two sets of yarns to make a fabric, while knitting involves using a single yarn to create a series of interconnected loops. These methods are the primary ways fabrics for clothing and other uses are made.
7. If you had to create a fabric for summer clothing, why would you choose a natural fibre like cotton over a synthetic one like polyester?
For summer clothing, cotton is a better choice than polyester because of its natural properties. Cotton is highly breathable and can absorb sweat, which helps keep the body cool and dry in hot weather. In contrast, polyester is not absorbent and traps heat and moisture against the skin, which can feel uncomfortable. This demonstrates a practical application of understanding fibre properties discussed in the chapter.
8. What key topics are covered in the NCERT textbook exercises for Class 6 Science Chapter 3, 'Fibre to Fabric'?
The NCERT textbook exercises for this chapter and their solutions cover several core concepts to test a student's understanding. The key topics include:
- The distinction between natural and synthetic fibres.
- The sources and processing of major plant fibres like cotton (including ginning) and jute.
- The process of spinning to create yarn from fibres.
- The primary methods of making fabric from yarn: weaving and knitting.
- The history and evolution of clothing materials.
