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.

Abstract: PCT No. PCT/AU94/00544 Sec. 371 Date May 13, 1996 Sec. 102(e) Date May 13, 1996 PCT Filed Sep. 13, 1994 PCT Pub. No. WO95/08012 PCT Pub. Date Mar. 23, 1995Apparatus for twisting a travelling strand includes a rotary structure rotatable about a rotational axis X-X and a series of pulleys mounted on the structure in an array disposed about the rotational axis X-X with each pulley in the series mounted on the structure for rotation about an individual axis of pulley rotation which is generally parallel to the axis X-X and moves around that axis on rotation of the structure. An input strand guide pulley guides an input strand to be twisted onto a path in which it will successively engage the pulleys and a strand exit guide pulley guides the strand from that path into an exit path along the axis X-X. The rotary structure is driven through a drive shaft and the pulleys are rotated by gearing.
