Claims
- 1. In a method for preparing a multi-functional additive involving irradiating raw cotton plant material with an electron beam source, continually blending the raw cotton plant material during the irradiating and micronizing the irradiated cotton plant material, the improvement wherein:the irradiating and blending of the raw cotton plant material is performed while the raw cotton plant material is in rope form; and the irradiated rope is suitably tensioned before micronizing to compensate for degradability of the rope incurred during irradiation.
- 2. The improvement of claim 1, wherein the irradiated rope is placed on at least one spool.
- 3. The improvement of claim 2, wherein the irradiated rope is fed to a roller and tensioning arrangement and a cutter before being micronized.
- 4. The improvement of claim 1, wherein after micronizing, the irradiated rope in powdered form is washed with a cleaning surfactant, agitated and dried so that the powdered cotton has a pH of 7.0.
- 5. A rope handling system for preparing a multi-functional additive from a raw cotton plant material comprising:at least one spool of irradiated rope formed from the raw cotton plant material; a roller and tensioning structure for receiving the irradiated rope from the spool; a cutter connected to the roller and tensioning structure for chopping the irradiated rope to a predetermined size; and a micronizing structure connected to the cutter for reducing the chopped irradiated rope to a reduced size.
- 6. The rope handling system of claim 5, wherein after passing through the micronizing structure, the irradiated rope in powdered form is washed, agitated and dried so that the powdered cotton has a pH of 7.0.
- 7. A rope handling system for preparing a multi-functional additive from a raw cotton plant material comprising:a pair of non-driven spools of irradiated rope formed from the raw cotton plant material; an idler compensating unit for receiving the ropes from the spools; an uncoiling and tensioning unit for receiving the ropes from the idler compensating units; a slack control unit for receiving the ropes from the uncoiling and tensioning unit; a cutter pinch roll feed unit for receiving ropes from the slack control unit; an inline cutter for receiving and cutting the ropes from the pinch roller feed unit; and a control unit for regulating the operation of the idler compensating unit, the uncoiling and tensioning unit, the slack control unit, the cutter pinch roll feed unit and the inline cutter; whereby the idler compensating unit compensates for the change in side to side angle as the ropes pay off the spools, the uncoiling and tensioning unit controls the feed rate of the overall system, and the slack control unit provides a constant rope tension and feed rate of the ropes into the pinch roll feed unit.
- 8. The rope handling system of claim 7, wherein the idler compensating unit includes a pair of non-driven, first idler rolls, a non-driven second idler roll above each first idler roll to keep the ropes captive in the grooves of the idler rolls, and a spring loaded tension roll for each rope.
- 9. The rope handling system of claim 7, wherein the uncoiling and tensioning unit includes an upper roll and a lower roll, both driven by a single, variable frequency controlled drive motor, there being a non-driven, hold down roll associated with each upper roll and lower roll.
- 10. The rope handling system of claim 7, wherein the slack control unit includes a series of upper, fixed, non-driven rolls and a set of floating lower rolls which move up and down according to the feed rates of the uncoiling and tensioning unit and the pinch roll feed unit.
- 11. The rope handling system of claim 7, wherein the cutter pinch roll feed unit includes a knurled driven roll and a pressure pinch roll associated with an air cylinder for forcing the pinch roll against the knurled driven roll.
- 12. The rope handling system of claim 7, wherein the rotary speed of the cutter and the lineal feed rate of the pinch roll feed unit determine the cut length of the irradiated rope fibers.
