As far as possible, thread type should be matched to the fabric being used. Therefore, use cotton thread for cotton fabrics, silk thread for silk fabrics and polyester thread for any heavier and/or manmade fabrics.
Knitted fabrics do not fray easily when cut, primarily because their interlocking loops provide structure and prevent unraveling. Unlike woven fabrics, which can fray at the edges, knitted textiles tend to maintain their integrity when cut. However, the degree of fraying can depend on the type of yarn used and the stitch pattern. It's often advisable to finish the edges or use techniques like overlocking if a clean edge is desired.
There are dozens of inventions for spinning fibers into thread, preparing cotton, wool and flax for use, etc, however, all fabrics that are not knitted use a loom to weave them.

It is a sewing machine needle that has a small ball at the tip, rather than the usual sharp point and is for used for stitching knitted or elasticated fabrics. As the ball enters the fabric, it pushes the fabric threads to one side rather than splitting them as a standard needle would and so is more "gentle". The holes that ball point needles leave in the fabric are larger than they would be with a standard needle, but because of the nature of knitted and elasticated fabrics, the holes become reasonably well hidden.
