Question

write a simple method to find out if a given thread is either cotton wool Silk or nylon​

Answer 1

Answer:

You could use high amounts of heat, and many more easier methods, to see if its cotton or nylon

Explanation:

When Nylon is under a lot of heat, it will melt and fuse. Cotton doesn't melt under a lot of heat but it may scorch. This is not an ideal method if you don't want to damage the thread though. So, you could also try...

• Pulling on the thread. (Nylon thread stretches as cotton does not.)
• Putting them under high amounts of light. (Nylon is sensitive to sunlight.)
• Dunking the thread in water. (Nylon holds less water than cotton does.)

And, that's all I have to say. Hope this helps. :)
