Definitions

  • cellulose sources that were useful in the production of absorbent products or tissue were not also useful in the production of downstream cellulose derivatives, such as cellulose ethers and cellulose esters.
  • the production of low viscosity cellulose derivatives from high viscosity cellulose raw materials, such as traditional kraft fiber, requires additional manufacturing steps that would add significant cost while imparting unwanted by-products and reducing the overall quality of the cellulose derivative.
  • Cotton linter and high a- cellulose content sulfite pulps which generally have a high degree of polymerization, are typically used in the manufacture of cellulose derivatives, such as cellulose ethers and esters.
  • the oxidation is carried out for a time and at a temperature that is sufficient to produce the desired completion of the reaction.
  • the oxidation may be carried out at a temperature ranging from about 75 to about 88 °C, and for a time ranging from about 40 to about 80 minutes.
  • the desired time and temperature of the oxidation reaction will be readily ascertainable by a person of skill in the art.
  • Fiber produced as described may, in some embodiments, be treated with a surface active agent.
  • the surface active agent for use in the present invention may be solid or liquid,
  • the surface active agent can be any surface active agent, including by not limited to softeners, debonders, and surfactants that is not substantive to the fiber, i.e., which does not interfere with its specific absorption rate.
  • a surface active agent that is "not substantive" to the fiber exhibits an increase in specific absorption rate of 30% or less as measured using the pfi test as described herein.
  • the specific absorption rate is increased by 25% or less, such as 20% or less, such as 15% or less, such as 10% or less.
  • the addition of surfactant causes competition for the same sites on the cellulose as the test fluid.
  • a surfactant is too substantive, it reacts at too many sites reducing the absorption capability of the fiber,
  • the reference standard for comparison with the surfactant treated fiber is an identical fiber without the addition of surfactant.
  • the kraft fiber is combined with at least one super absorbent polymer (SAP).
  • SAP may by an odor reductant.
  • Examples of SAP that can be used in accordance with the disclosure include, but are not limited to, HysorbTM sold by the company BASF, Aqua Keep ® sold by the company Sumitomo, and FAVOR ® , sold by the company Evonik.
  • the fifth or finai chlorine dioxide stage (D2) was carried out at a temperature of 72°C, and a pH of 4.4 with 0.14% C!0 2 applied.
  • k/s is the ratio of the absorption coefficient (k)/ scattering coefficient(s). k is directed affected by chromophores or color bodies in the pulp, so a change in k/s upon aging gives a direct measure of the amount of chromophore formed, k/s is calculated according to the formula:
