摘要： A new class of polymeric additives for papermaking is disclosed as well as a process for their manufacture, a method for their use and a paper sheet containing the addition.. The additives can be used in paper manufacture as agents for improving retention, paper machine operation and the strength properties of the product. The additives are manufactured from the biomass that is a by-product of microbiological production of citric acid by a fermentation process using Aspergillus Niger, suitable by-product from other microbiological process, or from a biomass specifically produced for this purpose. The biomass that contains acetyl amino groups or other amides is chemically modified by hydrolysis of the amides to form primary amino groups. Under neutral or acidic conditions these primary amines become cationic, which assures a good absorption of the additive onto fibres and fines of pulp that is generally of anionic nature. Furthermore, primary amino groups can form chemical bonds with carbonyl groups, and ionic interactions with carboxyl groups. Both these groups are abundant in the fibres and fines of pulps, especially in mechanical pulps. The additive prepared in this manner might contain glucosamine polymers that might be chemically bound to a carbohydrate polymer or oligomer. Novel papermaking additives produced in this manner are particularly suitable for the production of paper from fibrous pulp suspensions produced at least partially from mechanical pulps, the high negative charge of which tends to overwhelm a majority of conventional cationic polymers.
摘要翻译：公开了一类新型的造纸用聚合物添加剂及其制造方法，其使用方法和含有该添加剂的纸张。添加剂可用于造纸作为改善保留剂，造纸机操作的试剂和产品的强度性能。添加剂由生物质制成，生物质是通过使用黑曲霉的发酵方法生产柠檬酸的副产物，其他微生物过程的合适的副产物或由此产生的生物质。含有乙酰氨基或其它酰胺的生物质通过酰胺水解而化学修饰形成伯氨基。在中性或酸性条件下，这些伯胺是阳离子的，这确保了添加剂对通常具有阴离子性质的纸浆的纤维和细粉的良好吸收。此外，伯氨基可与羰基形成化学键，并与羧基形成离子相互作用。这两个组在纸浆的纤维和细粉中都是丰富的，特别是在机械纸浆中。以这种方式制备的添加剂可能含有可能与碳水化合物聚合物或低聚物化学结合的葡糖胺聚合物。以这种方式生产的新型造纸添加剂特别适用于从至少部分由机械纸浆生产的纤维纸浆悬浮液生产纸张，其高负电荷倾向于压倒大多数常规阳离子聚合物。

摘要： A novel method is disclosed to produce on a commercial scale, high aspect ratio cellulose nanofilaments (CNF) from natural lignocellulosic fibers. The method consists of a multi-pass high consistency refining (HCR) of chemical or mechanical fibers using specific combinations of refining intensity and specific energy. The CNF produced by this invention represents a mixture of fine filaments with widths in the submicron and lengths from tens of micrometers to few millimeters. The resultant product is made of a population of free filaments and filaments bound to the fiber core from which they were produced. The proportion of free and bound filaments is governed in large part by total specific energy applied to the pulp in the refiner. These CNF products differ from other cellulose fibrillar materials by their higher aspect ratio and the preserved degree of polymerization (DP) of cellulose. The CNF products made by this invention are excellent additives for the reinforcement of paper, tissue, paperboard and packaging products, plastic composite materials and coating formulations. They display exceptional strengthening power for never-dried paper webs.

摘要： This invention relates to a novel method to prepare aqueous furnishes useful as feedstock in the manufacture of very high-mineral content products, particularly paper sheets having mineral filler content up to 90% that display the required physical properties for the intended applications. The furnishes comprise fibrillated long fibres/mineral fillers mixed with anionic acrylic binders and co-additives, in presence or absence of cellulose fibrils. The fibrillated long fibres and cellulose fibrils provide high surface area for greater filler fixation and the reinforcement backbone network that ties all of the product components together. The anionic binders allow rapid and strong fixation of filler particles onto the surfaces of fibrils when mixing is conducted at temperatures higher than the glass transition temperature (T g ) of the binder. To the novel aqueous formulation can be added other functional and process additives commonly used in the manufacture of paper and paperboard packaging by single, multilayer and multiply papermaking forming processes. The aqueous formulation can also be used to fabricate shaped items by the known pulp moulding processes. The aqueous formulations provide excellent filler retention and drainage during product fabrication.

摘要： Cellulose nanofilaments from cellulose fibers, a method and a device to produce them are disclosed. The nanofilaments are fine filaments with widths in the sub-micron range and lengths up to a couple of millimeters. These nanofilaments are made from natural fibers from wood and other plants. The surface of the nanofilaments can be modified to carry anionic, cationic, polar, hydrophobic or other functional groups. Addition of these nanofilaments to papermaking furnishes substantially improves the wet-web strength and dry sheet strength much better than existing natural and synthetic polymers. The cellulose nanofilaments produced by the present invention are excellent additives for reinforcement of paper and paperboard products and composite materials, and can be used to produce superabsorbent materials.

摘要： A continuous filler treatment process has been developed to enhance the fixation of anionic latex on filler in a short time. In this process anionic polymer dispersions (latex) are added to common papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (T g ) of the latex used. To efficiently fix the latex the temperature of the filler/latex mixture must be 30-60°C higher than the T g of the latex used. The chemical composition of the resin and the type of surfactant used during the emulsion polymerisation process of the polymer latex dispersions are important factors for efficiently fixing the latex onto the filler by adding hot water and improving the properties of paper made with the treated filler. The enhanced fixation of anionic latex onto filler using hot water is done in mixing vessels that can control shear and mixing time. The anionic latexes applied by this process are totally and irreversibly fixed or bound onto the filler particles and the aggregated filler slurry is stable over time. The latex-treated filler slurry can be added to papermaking furnishes at any point prior to the headbox of the paper machine or stored for later use. It can be added to wood-free or wood-containing furnishes commonly used for making fine papers, mechanical pulp papers, and multi-ply paperboards. The latex-treated filler slurry improves filler retention, only slightly reduces sheet strength and improves sizing performance. Furthermore, latex-treated calcium carbonate filler, such as precipitated calcium carbonate (PCC), is more acid-resistant and, when used in manufacturing mechanical pulp paper under neutral conditions, less acid is needed to control the pH.
摘要翻译：已经开发了连续的填料处理方法，以在短时间内增强阴离子胶乳在填料上的固定。在这个过程中，将阴离子聚合物分散体（胶乳）在环境温度下添加到普通的造纸填料浆料中，然后与高于所用胶乳的玻璃化转变温度（Tg）的温度的水混合。为了有效地固定胶乳，填料/胶乳混合物的温度必须比所用胶乳的Tg高30-60℃。树脂的化学成分和在聚合物胶乳分散体的乳液聚合过程中使用的表面活性剂的类型是通过加入热水和改进用经处理的填料制备的纸的性能来有效地将胶乳固定到填料上的重要因素。使用热水将阴离子胶乳固定在填料上进行，可以控制剪切和混合时间的混合容器。通过该方法施加的阴离子胶乳完全和不可逆地固定或结合到填料颗粒上，并且聚集的填料浆料随时间稳定。胶乳处理的填料浆料可以在造纸机的流浆箱之前的任何时间添加到造纸装置中，或者储存以备后用。它可以添加到通常用于制造高级纸张，机械纸浆纸和多层纸板的无木材或含木材的配料中。胶乳处理的填料浆料改善了填料保留性，仅稍微降低了片材强度并提高了施胶性能。此外，胶乳处理的碳酸钙填料，例如沉淀碳酸钙（PCC），更耐酸，并且当在中性条件下用于制造机械纸浆时，需要较少的酸来控制pH。

摘要： A filler treatment comprising the preparation of swollen starch-latex compositions, prepared in the presence or absence of co-additives, and the addition of the said composition to a filler suspension, has been developed. Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch-latex compositions can be prepared in a batch or jet cooker, or by mixing (7) with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch-latex composition is then rapidly mixed with the filler slurry (5), preferably in a static mixer (6), and added to the papermaking furnish (1) at a point prior to the headbox (3) of the paper machine. The starch-latex composition can be used with wood-free or wood-containing furnishes. The treated filler is easily retained in the web during papermaking, improves drainage, and gives sheets having good formation. Sheets made with the treated fillers have higher bonding and tensile strengths than sheets produced using filler treated with either swollen starch alone or latex alone.
