FAQs on Processing Fibres into Wool(all steps) Video Lecture - Advance Learner Course: Science Class 6

1. What is the process of processing fibres into wool?
Ans. The process of processing fibres into wool involves several steps. First, the wool is sheared from the sheep's body. Then, the wool undergoes cleaning, where dirt, grease, and other impurities are removed. After cleaning, the wool is carded to align the fibres in a parallel manner, making it easier to spin. Next, the carded wool is spun into yarn using spinning machines. Finally, the yarn is woven or knitted to create different woolen products.
2. How is wool cleaned during the processing?
Ans. Wool is cleaned during the processing by removing dirt, grease, and other impurities. This is done through a process called scouring. The wool is soaked in hot water mixed with detergent or soap to remove the dirt and grease. It is then rinsed multiple times to ensure all the impurities are removed. The cleaned wool is then ready for further processing.
3. What is carding and why is it necessary in the wool processing?
Ans. Carding is a process in which the wool fibres are aligned in a parallel manner. This is done using carding machines that have a series of wire teeth. The wool is passed through these wire teeth, which separate and straighten the fibres. Carding is necessary in wool processing as it makes the fibres more uniform and easier to spin into yarn. It also helps in removing any remaining impurities and creating a smooth and consistent texture in the wool.
4. How is wool spun into yarn?
Ans. Wool is spun into yarn using spinning machines. First, the cleaned and carded wool is stretched and twisted to form a continuous strand called a roving. The roving is then fed into the spinning machine, where it is further twisted and drawn out to create a long, thin yarn. The spinning machine controls the tension and speed of the twisting and drawing process. The resulting yarn can then be used for weaving or knitting.
5. What are the final steps in the wool processing?
Ans. The final steps in the wool processing include weaving or knitting the yarn into woolen products. Weaving involves interlacing the yarns at right angles to create a fabric, while knitting involves interlocking loops of yarn to create a fabric or garment. These processes can be done manually or using machines, depending on the scale of production. The finished woolen products are then subjected to finishing processes like washing, dyeing, and pressing to enhance their appearance and texture.
