    摘要： A hydrophobically sized fibrous web layer, preparation of a fibrous web or a fibre-based coating, a multiplayer board product having at least a middle layer formed of said fibrous web, as well as use of a heat-sensitive surfactant for said methods and products, whereby microfibrillated cellulose (MFC) and hydrophobic size are brought to a foam with water and the heat-sensitive surfactant, the foam is supplied to a forming fabric of a paper or board machine, dewatered by suction of air through the forming fabric, and dried to a web product. Alternatively the foam may be supplied onto a premade fibrous web and dried to form a coating layer. The hydrophilic functionality of the surfactant contained in the web may be destroyed by heating. Pulp of a greater fibre length, such as CTMP, may be included, to provide improved wet and dry tensile strength for the paper and board products.

    摘要： A preparation of high strength paper by incorporating a polymeric film into the paper web during the paper making process is provided. The polymeric film is either a cold water soluble film or hot water soluble film or water insoluble hydrophilic film or non soluble non hydrophilic film or a combination of cold+hot+cold water soluble film or cold+hot water soluble film or cold+non soluble hydrophilic film or cold+non soluble hydrophilic film+cold water soluble film or cold+non soluble non hydrophilic film or cold+non soluble non hydrophilic film+cold water soluble film or slit strips of one or many of these combinations woven or intertwined offline and incorporated into the paper during the paper making process. Zone coating or discreet printing or zone extrusion striping or formation of hot water soluble film on preformed cold water soluble film which is then inserted into paper during the paper making process, thus using cold water soluble film as a carrier is also provided. The combination of the water soluble film(s) may be plain or wholly or partially perforated.

    摘要： The invention provides hydrolases, polynucleotides encoding them, and methods of making and using these polynucleotides and polypeptides. In one aspect, the invention is directed to polypeptides, e.g., enzymes, having a hydrolase activity, e.g., an esterase, acylase, lipase, phospholipase (e.g., phospholipase A, B, C and D activity, patatin activity, lipid acyl hydrolase (LAH) activity) or protease activity, including thermostable and thermotolerant hydrolase activity, and polynucleotides encoding these enzymes, and making and using these polynucleotides and polypeptides. The hydrolase activities of the polypeptides and peptides of the invention include esterase activity, lipase activity (hydrolysis of lipids), acidolysis reactions (to replace an esterified fatty acid with a free fatty acid), transesterification reactions (exchange of fatty acids between triglycerides), ester synthesis, ester interchange reactions, phospholipase activity and protease activity (hydrolysis of peptide bonds). In another aspect, the invention provides methods for hydrolyzing steryl esters and triglycerides (e.g., in a paper pulp), into sterols, glycerol and free fatty acids, using enzyme(s) of the invention. The invention provides enzymes and methods for decreasing the amount of lipophilic extracts (“pitch”) in a pulp-comprising composition. The polypeptides of the invention can be used in a variety of pharmaceutical, agricultural and industrial contexts, including the manufacture of cosmetics and nutraceuticals.
