Today’s clothing contains so many man made fibers (read plastic) that produce toxic fumes when burned most people stay away from it now. I use cotton balls and Vaseline, which makes an excellent (and cheap) fire starter. Just make sure you buy 100% cotton balls not some made with other fibers. Most people tend to use too much Vaseline when first making these so just remember to use a small amount to start and work it in to the ball. You should not be able to squeeze any Vaseline out of the ball, if you can you are using too much. Like everything else practice with it to learn how it works and what you can expect from it.
