    摘要： A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about 1 and about 9, preferably between 3 and 7, and (b) subjecting Use treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp. A pulp of modified SW fibers and a mixture of HW fibers and modified HW fibers are disclosed.

    摘要： Provided is a process for producing bleached pulp, including subjecting unbleached pulp, which is obtained by cooking a lignocellulose substance, to alkali-oxygen bleaching treatment and then subjecting the alkali-oxygen bleached pulp to chlorine-free bleaching treatment including chlorine dioxide treatment, wherein in at least one chlorine dioxide treatment stage in which the chlorine dioxide treatment is performed, monopersulfuric acid is used in combination. The amount of chlorine dioxide to be used is reduced and the color reversion resistance of the bleached pulp is improved by this process.

    摘要： A method is provided for controlling organic contaminants, such as xylans, pitch or both, that interfere with bleaching of fibers and/or cause other interference(s) in papermaking systems. The method includes contacting fibers before any bleaching thereof with a composition which contains a hemicellulolytic enzyme and an organic contaminant removal adjuvant to liberate the organic contaminants from the fibers. The treated fibers can then be bleached and further used, for example, in making paper. The present invention also relates to the treatment compositions and to paper products made with fiber materials treated with these compositions. A method of enhancing enzymatic degradation of a substrate as well as formulations and systems for achieving the same are also provided. Various substrates can be degraded or otherwise processed, including biomass, paper mill sludge, and animal hides. Enzymatic degradation can be enhanced by including one or more polymeric surfactants.

    摘要： The present invention relates to an improved process for producing chemical cellulose pulp wherein biopolymers are added immediately before, during or after a bleaching step, depending on pulp characteristics and on process conditions used. The biopolymers according to the present invention are starch by an etherification reaction. This treatment results in a differentiated pulp having improved physical, chemical and mechanical properties when compared with cellulose pulps obtained by traditional processes. The use of said biopolymer alters the relations between important pulp properties rendering their application in papermaking process advantageous. This differentiation increases the possibilities of use and also of new applications, including for the substitution of pulps produced from other cellulose sources. Thus, the present invention also relates to a process for the preparation of paper, such as printing, writing, decorative, special or tissue-type papers, through the use of the cellulose pulps modified by the above process.
