Abstract: A bamboo fiber material, which is manufactured via the following steps: (1) preparation of bamboo oil: (2) preparation of bamboo fiber: (3) mixing the bamboo oil, a water-proofing agent and sodium chloride, adding water in an amount of 2-5 times of the weight of the mixture, stirring at 15-20° C. for 5-10 minutes; (4) adding the bamboo fiber obtained in step (2), as well as a natural resin powder and an edible starch, stirring at 18-20° C. for 2-5 minutes; finally adding a titanium dioxide and stirring uniformly to obtain the bamboo material. The bamboo fiber material of the present invention is made from natural bamboo as main raw material, taking inherent advantages of bamboo such as antibacterial, anticorrosive, non-toxic and less side-effect. In addition, other raw materials are also all environment-friendly materials, so that the bamboo fiber material is free of volatile chemicals.

Abstract: Disclosed herein are compositions, methods and systems for bamboo pulping. Bamboo biomass materials that are exclusively or largely uniform are used for bamboo pulping. In some embodiments, the bamboo biomass materials are derived from a pure stand or monoculture of bamboo. In some embodiments, the bamboo pure stand or monoculture is generated by micropropagation comprising meta-topolin or an analogue thereof and/or thidiazuron or an analogue thereof.

Abstract: A system for collecting ligno-cellulosic biomass over a large area to enable the commercial refining of biomass from 2,500 to in excess of 50,000 tons of biomass per day to produce ethanol or other products. The biomass is collected at a series of collection points and then transported through a network of conduit “loops” interconnecting each of the collection points and the central refining plant. The water used to transport the biomass, as a slurry, is recovered and sequentially recycled in the same pipeline system to push the biomass slurry around the system in a “loop.” The outgoing and return legs of each loop optionally are located adjacent each other.

Abstract: The present invention relates generally to the timber products industry, and particularly to methods and apparatus for the separation of bast fibers. More particularly, the present invention relates to methods and apparatus for use in the separation of inner core from outer bast of bast plants using soaking, cutting, and scrimming methods and apparatuses.

Abstract: A method to chemically treat light weight, bulky cellulosic material including: introducing the material to an upper inlet of a substantially vertical treatment vessel; maintaining the material in the vessel at a pressure of at least 20 bar and at a temperature of at least 200° C.; treating the material with a cooking liquor in the vessel; moving the material past at least one anti-compression ring on an inside surface of the vessel, as the material moves downward through the vessel; agitating the material in the vessel, and discharging the treated material from a lower discharge port of the vessel.

Abstract: In this patent, fibers have been successfully extracted from various natural occurring materials using a series of chemical, biological and mechanical methods. Moreover, these fibers can be conjugated onto certain polymer chains via coupling agent and chemical modification. Consequently, the thermal stability and mechanical properties of the polymers can be dramatically elevated with the incorporation of these fibers. The intended polymers include conventional plastics (epoxy resins, polyesters and polyolefins etc.), rubbers (natural rubbers and thermoplastic rubbers etc.) and biodegradable polymers. Apart from the enhancement of mechanical properties and thermal stability, the incorporation of natural fibers can reduce the production cost of the materials and meet the demand of environmental protection.

Abstract: A process for producing dissolving pulp includes a degumming step using a degumming liquor which includes hydrogen peroxide and ammonia.

Abstract: A process based on formic acid cooking for producing pulp from herbaceous plants and deciduous trees by using acetic acid as an additional cooking chemical. The obtained pulp can be used in fine paper and board production as short-fibered material, for instance. The invention also relates to a process for adjusting the hemicellulose content of the pulp in connection with the formic acid cooking by using acetic acid as an additional cooking chemical.

Abstract: Composite panels and pulp, and paper products of the pulp, are produced from Arundo donax. In the fabrication of the composite panels, Arundo donax is comminuted to a suitable size, combined with a binder, and consolidated into panels that meet standards for construction and/or furniture grade panels. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. Comminuted Arundo donax is treated, in conventional pulping processes, to produce a high tensile strength pulp that can be used in the production of paper. The pulp has a lighter color than wood pulp, and thereby uses less bleaching chemicals to achieve a desired whiteness. The pulp can be combined with wood pulp to produce a variety of products.

Abstract: Bamboo fibers are utilized to serve as a reinforcing material and for manufacturing an inorganic molded body. In order to produce the bamboo fibers with excellent durability, in a first step bamboo material is compressed to be roughly crushed and in a second step the roughly crushed bamboo material is fiberized using a grinding machine. The moisture content of the bamboo material subjected to the first step is set to be more than 65%. After the completion of at least one of the first and second steps a drying step is taken so that the moisture content of the bamboo material is adjusted to within the range of 3 to 35%.

Abstract: A method of producing high quantities of ethanol and a high quality pulp to produce a variety of papers. The method comprises preparing the bamboo by chipping, shredding and washing. This bamboo fiber is then processed in two stages of prehydrolysis to separate the ethanol producing portion from the pulp producing portion. The ethanol producing portion is condensed and subject to enzymatic hydrolysis and fermentation to produce an ethanol product. The pulp producing portion is processed in two stages of digestion to produce a pulp in high yield that is suitable to produce a variety of papers.

Abstract: Bamboo can be formed into a suitable pulp if prior to digestion it undergoes a process of shredding, washing and wet depithing. The fibers are then chemically digested preferably by a process which uses rapid pressure drops to open the fibers using the energy contained in the wet superheated fibers.

Abstract: A process for thermomechanical digestion using a multiple blowdown technique. The digestion chemical is added just prior to blowdown which results in a concentration of digesting chemicals on the fiber. The process can be carried out with a digester having multiple chambers, each at a lower pressure has many advantages in forming pulps suitable for newsprint or fine papers from wood and vegetable fiber sources. The digester should be of a kind where the fiber will have a greater residence time in subsequent chambers.

Abstract: The brightness of a thermomechanical pulp can be improved if a serial multiple blowdown technique is used and a bleachant is present at an effective concentration throughout the thermomechanical pulping process.
