Definitions

  • Cellulose beads are known to be reproducible, but in general they are hard, inflexible and used for air filtration or aroma control etc. A method was required to make a low weight, flexible bead, with good resilience and conformability, to replicate the function of the EPS bead in packaging.
  • Beads with a diameter of more than 2mm are also thought to cavitate easier and so have more internal space. Additionally, they are easier to handle on a packing line, as smaller beads can display some static properties which are not seen with the larger beads. This is also an advantage over materials such as polystyrene, as the static properties displayed by the beads can make filling an article with the beads more difficult.
  • the beads can be produced from a mixture comprising a salt composition and a viscose composition, wherein the salt composition produces a gas when added to a regeneration bath, and the viscose composition has a Hottenroth number within the range of approximately 4 to approximately 17. Alternatively, the Hottenroth number may be from 5 to 15, from 6 to 14, from 7 to 13, from 8 to 10, or approximately 8.5.
  • the pre-dried regenerated cellulose bead may include from 5 to 50%, from 10 to 40% or from 15 to 35% by weight cellulose, and from approximately 1 to 30%, 5 to 25% or 10 to 25% by weight softeners. Softeners may be selected from the group consisting of glycerine, PEG, MPG, and TEG.
  • the term "pre-dried bead" refers to the bead once it is formed but before any drying process occurs. The remainder of the weight may comprise water.
  • the present invention also provides a method of forming a regenerated cellulosic bead wherein air is included when mixing the viscose with water and salt composition.
  • the present invention also provides a method of forming a cellulosic regenerated bead wherein the mixing further comprises including softeners and functional additives.
  • the viscose is forced through the dye head at a pressure such that the viscose can form individual droplets rather than forming a continuous stream of viscose.
  • the required pressure changes depending on the formulation. For an up-scaled process, a large number of dye heads can be used to make the process commercially viable.
  • These materials would include a range of “softeners” such as glycerine, PEG,
  • the beads were tested for composition and found to be approximately 25% cellulose (by weight), 13% glycerine (by weight) and 62% water (by weight). The beads had an average size of 2-3 mm. The final bead was found to have a bulk density of 190 g/L.
  • the needle head was set 14 cm above the acid level and the acid was heated to 60 ° C and a magnetic flea added to stir the acid to create a vortex that could submerge the beads during regeneration.
  • the final bead had a density of 90 g/L.
  • Example 4 Alterative low density bead formulation I [00107]
  • Example 4 uses calcium carbonate as the salt to generate gas in the regeneration bath.
  • Example 5 uses calcium carbonate as the selected salt to generate gas in the regeneration bath.
