Question

Which fibre shrinks if burns and forms a black bead along with sooty flame?

Answer 1

Answer:

The burn test is a simple, somewhat subjective test based on the knowledge of how

particular fibers burn. Be prepared to note the following when testing your fibers:

 Do the fibers melt and/or burn?

 Do the fibers shrink from the flame?

 What type of odor do the fumes have?

 What is the characteristic(s) of any smoke?

 What does the residue of the burned fibers look like?
