A method for producing parenchymal cell cellulose by using a high consistency alkali treatment and an optional refinement step, as well as an apparatus for its manufacture.

Method for producing parenchymal cell cellulose

Methods for manufacturing, re-activating and using compositions including fibrillated parenchymal cellulose and activator are provided. The activator has a low molecular weight and is used to facilitate reactivation.

Parenchymal cellulose composition

The invention relates to a method for producing paper, board or the like. The method comprises obtaining a thick stock comprising cellulose fibres, forming a fibrous web and drying of drying the fibrous web. A strength agent system, which comprises at least one synthetic or natural polymer, or their mixture, and microfibrillated parenchymal cellulose material originating from non-wood sources, is added to the thick stock. The invention relates also to paper or board produced by the method.

Method for producing paper, board or the like

A method of producing from cellulose pith a composition having bimodal distribution of its components. The composition can be used to modify rheological properties of compositions of matter and for making articles of manufacture and nanocomposites.
