In the process for orienting molecular chains, for example dyneema, does the volume of the polymer change? In the process for creating dyneema, the fibers are drawn, heated and elongated. Would this change the volume of fiber? I know the density for dyneema is listed at .97. The density of uhmwpe is listed at .94. I want to say it loses volume but these figures could be wrong. I was hoping there was a common sense answer from a molecular structure point of view.
