Fibre to Fabric
Given below is a sequence of steps in the processing of wool. Which are the missing steps? Add them.
Shearing, __________, sorting, __________, __________, _________.
Wool is the natural fibre that is obtained from the body of an animal. It comes from sheep, goats, camel and some other animals also. The correct order of converting fibre to wool is shown below:
1. Shearing- Shearing is the process in which hairs, along with a thin layer of skin is removed from the body of the animal as shown in the figure given below how man is removing hairs from sheep’s body.
2. Scouring-Scouring is the process in which hairs are thoroughly washed in tanks filled with soapy water to remove dust and dirt as shown in the figure given below.
3. Sorting-After shearing and sorting are done, the hairy skin is sent to a factory where hairs of different textures are separated
4. Removing Burr-Burr is the small fluffy fibres that are taken out of the hairs.
5. Dyeing-It is the process of colouring fibres that are obtained from the hairy skin of animals because fibres have the only colour like white, brown, and black only.
6. Spinning-Spinning is the process of making yarn from fibres. In the given figure with the help of a machine, fibres are straightened, combed, and rolled into yarn. The longer fibres are made into wool for sweaters and shorter fibres are spun and woven into woollen clothes.
Hence, the correct sequence to process wool is:
Shearing, scouring, sorting, removing burr, dyeing, spinning.

What our students and parents say about us!
Saiyam is using EduSaksham online courses from past one year. He is able to complete his tutorials, worksheets, and assignments on his own. Once he is done with worksheets, he can check his answers and if he has done any mistakes, then he can check the correct answers and explanations. They have been given so well that he is able to understand them himself and rarely he asks us for any clarification. He enjoys using the platform and has learned and improved a lot in Mathematics. I would recommend EduSaksham to all parents who want their kids to learn in a structured way and also enjoy the learning process.
Neeraj (Saiyam's Father)
I would like to thank Edusaksham on behalf of my son Aditya who attended " Math Olympiad crash course for 5 weeks". As per Aditya, this course helped him to understand new topics like Roman numerals and decimal places which were not taught in his school till date and had a better understanding of other topics. I personally thank EduSaksham for all the help and support.
Geeta Bansal (Aditya's Mother)
We had a good experience with EduSaksham. Because sheets are available online, Vedant enjoyed doing more and more sheets without any reminders. I could leave him on his own as he was very much motivated to cover the topics. Practice is very important in maths but it becomes difficult for us to prepare sheets, I am glad we found EduSaksham where in a lot of in a lot of sheets are available for practice and the quality of questions are also good. As it's a venture from IITians we could think of giving it a try and I am glad we tried
Shikha Chowdhary (Vedant's Mother)
I have grown up in a family where my father used to give me practice maths paper every day which I need to finish before I go to play. I think that strong foundation of solving new questions every day helped me to clear my IITJEE exam. But as working women, I always had time challenge to create practice Math papers for my daughter. Thanks to EduSaksham, their questions are so logical and conceptual that I don't feel the guilt of not creating practice questions by myself :). There are plenty of worksheet along with the tutorials for each chapter. It has made parents life easier :) And the best part is my daughter loves doing it. Thank you EduSaksham.
