    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: A method and apparatus for continuously pressure decatising a fabric include a rotatable drum (12) around which an endless belt (15) is arranged to travel for conveying a fabric (19) (and optionally a moisture laden textile (20)) between the facing surfaces of the belt (15) and the drum (12). The drum (12) is heated and fabric (19) is pressed between the belt and the drum as it is conveyed through the apparatus. The fabric (19) is subjected to pressurized saturated steam, which may be generated by evaporation of the moisture in textile (20) when it contacts the heated drum, as it is pressed. Various options other than use of a moisture laden textile (20) for supplying the steam are disclosed. The invention involves enclosing the drum in a pressure vessel (14) within which a compressed air atmosphere at ambient temperature is maintained. The surrounding compressed air atmosphere can be used to control the steam temperature, that is, the saturated steam temperature can be changed by changing the pressure of the surrounding compressed air. The surrounding compressed air atmosphere also reduces the sealing requirements for the steam treatment and belt wear. The method and apparatus are also applicable for setting staple fibers.

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.

    Abstract: Apparatus for twisting a travelling strand comprises a rotary structure (12) rotatable about a rotational axis X-X and a series of pulleys (48, 50, 52, 54 and 56) mounted on structure (12) in an array disposed about the rotational axis X-X with each pulley in the series rotatably mounted on structure (12) 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 (12). An input strand guide pulley (60) guides an input strand to be twisted into a path in which it will successively engage the pulleys (48, 50, 52, 54 and 56) and a strand exit guide pulley (62) guides the strand from that path into an exit path along the axis X-X. Rotary structure (12) is driven through a drive shaft (16) and the pulleys (48, 50, 52, 54 and 56) are rotated by gearing (32).
