Abstract
Disclosed herein are novel methods to prepare paper pulp from non-wood fiber sources, and preferably from a variety of different non-homogeneous fiber sources. The methods use a unique combination of caustic and temperature without a digestor to improve performance of the resulting fibers.
Claims16
A method for forming fiber pulp suitable for paper, the method comprising
- selecting a non-homogeneous agricultural waste fiber
- optionally treating the non-homogeneous agricultural waste fiber with anti-microbial solution and/or UV light;
- mechanically pre-treating, and optionally chemically pre-treating, the non-homogeneous agricultural waste fiber by dry refining and optionally pre-screening the non-homogeneous agricultural waste fiber to remove contaminants and any undesirable pulp feedstock fibers;
- heating or cooking the non-homogeneous agricultural waste fiber with low concentrations of sodium hydroxide and/or peroxide at low temperatures to form cooked fibers;
- high consistency refining of the cooked fibers to develop desired strength properties;
- diluting and/or rinsing the heated or cooked fibers;
- screening the rinsed fibers and optionally re-processing rejected fibers through chemical and refining processing;
- and
- drying the fibers to form the fiber pulp.
