  • Patent number: 10590608
    Abstract: 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 starches chemically modified 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.

  • Patent number: 10400394
    Abstract: A method for treating cellulosic fibers to improve paper, board and tissue quality; the method involves splitting fibers from feed pulp into an original portion containing original fibers and a refineable portion containing original fibers. The refinable portion is refined to create a refined portion containing refined fibers. Varying amounts of the original unrefined fibers and refined fibers are blended together to form a recombined slurry that is processed by a paper machine into an optimized paper product. A master control system and fiber measurement system are integrated with the overall system to regulate all processing.

  • Publication number: 20150013926
    Abstract: An improved processes for making fluff pulp sheets mechanically eliminates many of the unwanted fiber-to-fiber bonding (fiber bundles) which may be contained in the sheet to produce consistent and uniform quality fluff pulp. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break a majority of fiber bundles contained in the web. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. A shoe press can be used to dewater the web after it is subjected to the pulsating shear forces. The web can be dried utilizing conventional drying equipment, such as cylindrical driers.

The invention also relates to moistening of paper or board, with a dry matter content of over 40%, in acidic water, after which the pH value is raised with an alkali, and the paper or board is dried, or it is dried after the moistening without raising the pH value.

  • Patent number: 8758562
    Abstract: The invention relates to a method for increasing the benefit from starch in pulped, preferably repulped cellulosic material at paper or paperboard manufacturing comprising the steps of (a) pulping a cellulosic material containing a starch; (b) treating the cellulosic material containing the starch with one or more biocides, preferably in the thick stock area; and (h) adding an ionic polymer and preferably, an auxiliary ionic polymer to the cellulosic material; wherein the ionic polymer and the optionally added auxiliary ionic polymer preferably have a different average molecular weight and preferably a different ionicity, wherein the ionicity is the molar content of ionic monomer units relative to the total amount of monomer units.

  • Patent number: 8741103
    Abstract: The present invention has an object to provide staple fibers suitable for manufacturing a wet-laid nonwoven fabric having excellent adhesive strength and heat resistance at a reduced environmental burden, a manufacturing method of the same, and a nonwoven fabric using the staple fibers. The object can be achieved by polyalkylene terephthalate or polyalkylene naphthalate staple fiber wet nonwoven fabric having excellent adhesive strength and heat resistance that are provided by blending and thermal-compression bonding of low oriented yarn and fully oriented yarn, wherein a specific ratio of biomass-derived carbon, fineness, fiber length, and a weight ratio between fully oriented staple fibers and low oriented staple fibers in the wet-laid nonwoven fabric are used to obtain a fine low oriented yarn having excellent binder performance and a fine fully oriented yarn having an unprecedented level of fineness.

  • Patent number: 8741104
    Abstract: Fibrous cellulosic products incorporating both conventional cellulosic fibers and laterally expanded cellulose fibers exhibit exceptional porosity, bulk, absorbency and resiliency properties. Typical products include absorbent tissue products, absorbent fluff products and flat papers. The laterally expanded cellulose fibers exhibit: (i) a broadened X-Ray diffraction peak for the most prominent reflection having a width at half-height, (W1/2h)A, of at least about 3.0° 2?, (ii) broad overlapping maxima in their Raman spectrum between 285 and 500 cm?1, the height of the two tallest of said maxima in said spectrum between 285 and 500 cm?1 being between 35 and 50% of the height of the peak near 1098 cm?1 and (iii) a blue stain when treated with Graff C-stain, the stain exhibiting less red than the stains exhibited with bleached hardwood kraft fibers and bleached softwood kraft fibers.

  • Patent number: 8734615
    Abstract: The invention relates to a method for impregnating and drying a continuous paper web (1) by means of a urea resin dissolved in water, and to a corresponding system. Such paper webs (1) are employed for example as furniture foil or floor laminate, wherein in the known art melamine resin is used exclusively for bonding to a substrate. This is relatively expensive. Therefore the object of the invention is to create a method in which the paper web (1) which is impregnated by means of urea resin can be bonded to the substrate with a high degree of operational reliability. Said object is achieved in that the temperature of the paper web (1) is determined separately in each of the drying zones (3.1, 3.2, 3.3, 3.4), that for each of the drying zones (3.1, 3.2, 3.3, 3.4) an amount and/or a temperature of the circulating air are regulated so that the maximum temperature of the paper web (1) is 99° C., and that exhaust air is extracted from a first one of the drying zones (3.1, 3.2, 3.3, 3.
