Abstract: A process for stretching natural staple fibers to reduce the diameter includes the steps of treating a substantially untwisted traveling assembly of natural fibers to plasticize the natural fibers, twisting the traveling assembly sufficiently to substantially prevent drafting of the assembly during subsequent stretching, subsequently stretching the twisted assembly and setting the stretch. Staple fibers having reduced diameters are provided as a result of the stretching process.
