摘要： A pliable sheet is manufactured for use with smokable substances. The pliable sheet is completely sourced from female plants of the Cannabis genus. Source species include Cannabis sativa, Cannabis indica, or a blend thereof. A manufacture process entails processing and refining harvested plant material before it can be formed into the pliable sheet. After formation the pliable sheet is dried before it is ready for use. Flavoring and aromatic elements can be incorporated into the pliable sheet to enhance a smoking experience. Adhesives may also be integrated to facilitate rolling of the pliable sheet about smokable matter. Ideally, the adhesives are sticky oil extracts produced from plants of the Cannabis genus. The pliable sheet can be manufactured in a variety of thicknesses and sizes.

摘要： A method of making paper is described. The method includes providing a calcium bicarbonate solution an providing a cellulosic fibrous material, the cellulosic fibrous material comprising a plurality of elongated fibers having a fiber wall surrounding a hollow interior, the fibrous material having a moisture content. The method also includes adding the calcium bicarbonate solution to the cellulosic fibrous material to form a pulp mixture, the calcium bicarbonate solution containing from 0.5% to about 16% solids of calcium bicarbonate by weight. Further, the method includes dewatering the pulp slurry using a wet press device such that the solids of the calcium bicarbonate by weight is pulsed above and below 16% solids by weight, finally ending above 16% calcium bicarbonate by weight and refining the pulp mixture such that at least some of the calcium ions become associated with the reactive sites in the fiber walls. Further still, the method includes forming a web from the pulp mixture and wet pressing the web.

摘要： Nonwoven material produced by hydroentanglement of a wet-laid or foam-formed fibre web. The material comprises a mixture of short plant fibres, in particular pulp fibres, and long hydrophillic plant fibres, where the major portion of the fibres presents a fibre length which is at least 10 mm, whereby the portion of long fibres is at least 1 weight-% of the fibre weight. The fibres were mixed with each other in the presence of a dispersing agent which allows a uniform fibre formation, in a wet-laid or foam-formed fibre web which has been hydroentangled with sufficient energy to form a compact absorbing material.
