Spinning yarn in Fibre to Fabric – Class 6 Science Experiment
Chapter Name: Fibre to Fabric
Activity Name: Spinning yarn in Fibre to Fabric
Activity Description:
In this experiment, we will learn how to spin yarn from cotton fiber. We will start by removing the seeds from a cotton ball and then proceed to create yarn using the fiber. We will observe the strength of the yarn obtained through this process.
Required Items:
- Cotton ball
- Takli (spinning instrument) or Charka (spinning wheel)
Step by Step Procedure:
- Take a cotton ball and remove the seeds from it.
- Take a small portion of the cotton fiber in one hand.
- Gently start pulling out the cotton fiber using your thumb and forefinger. Continue pulling until you have a long strand of fiber.
- As you pull the fiber, twist it continuously using your fingers. This twisting action will convert the fiber into yarn.
- Repeat steps 2-4 with additional portions of cotton fiber until you have enough yarn.
Experiment Observations:
- Observe the process of pulling and twisting the cotton fiber to form yarn.
- Note the length and thickness of the yarn obtained.
- Evaluate the strength of the yarn by gently tugging on it.
Precautions:
- Handle the cotton fiber with care to prevent it from breaking.
- Be cautious while twisting the fiber to avoid tangling or breaking it.
- Keep the work area clean to avoid mixing impurities with the fiber.
Lesson Learnt from Experiment:
The yarn obtained by directly pulling and twisting cotton fiber is not strong enough to be used for weaving. This experiment highlights the importance of using spinning instruments like Takli or Charka to produce stronger yarn from fibers.
Spinning with the help of these tools enhances the strength and quality of the yarn, making it suitable for weaving fabric.
