The fibers that make up yarn just aren't that long. When you comb it out, the fibers are holding onto the knot in the middle. Any fiber that is not stuck into that knot is what gets pulled away. Individual fibers might be different lengths so you might get some variance in lengths, but you're never going to be able to get, say, an 8 inch long piece of combed yarn.
