  • Patent number: 10364303
    Abstract: An iminodiacetic acid type chelate resin which can be easily and efficiently produced and which can efficiently adsorb and separate metal ions; and a method for producing the same are developed. The use of a chelate rein having a carboxymethyl group introduced into primary amino groups of the polyvinylamine crosslinked polymer particles can facilitate the efficient adsorption and separation of metal ions in water. The chelate resin can be obtained by a production method in which an N-vinyl carboxylic acid amide is suspension polymerized with a crosslinkable monomer in salt water in the presence of a dispersant thereby to obtain a polyvinyl carboxylic acid amide crosslinked polymer particles, and the obtained polyvinyl carboxylic acid amide crosslinked polymer is hydrolyzed to thereby introduce a carboxymethyl group into primary amino groups of the polyvinylamine crosslinked polymer particles.

  • Patent number: 10081914
    Abstract: The invention provides a creped tissue web having satisfactory softness without the excess use of water insoluble creping compositions. The satisfactory softness levels, which may be measured as TS7, are generally less than about 10.0 and may be achieved by creping the tissue web with less than about 100 mg/m2? (milligrams of creping composition per square meter of creping cylinder surface area) such as from about 25 to about 100 mg/m2? and more preferably from about 50 to about 75 mg/m2?. It was previously believed that water insoluble creping compositions need to be added at high add-on levels, such as 100 mg/m2? or greater to achieve a desirable softness at a given tensile strength. It has now been surprisingly discovered that the add-on of water insoluble creping composition may be reduced significantly by adding a water soluble adhesive to the creping composition.

The improvement in both strike-through and absorbency is achieved in-part by increasing the basis weight of the web, while at the same time reducing the creping composition add-on levels.

  • Patent number: 8852400
    Abstract: The present disclosure provides for a method of preparing and using an emulsion for treating a papermaking process. The emulsion is an oil-in-water emulsion of alkenyl succinic anhydride emulsified with a polymer comprising at least one primary or secondary amine containing monomer. The method comprises adding an oil-in-water emulsion to the papermaking process; wherein the oil-in-water emulsion comprises alkenyl succinic anhydride emulsified with a polymer comprising at least one primary or secondary amine containing monomer; and wherein the oil-in-water emulsion is added in an amount sufficient to improve sizing of the paper produced by the papermaking process. The primary or secondary amine may be a secondary amine comprising diallylamine, and the polymer may be a diallylamine-acrylamide copolymer.

  • Patent number: 8840760
    Abstract: The object of the process of the invention is to increase the retention of starch in the sheet of paper in order to reduce operating costs and increase the physical characteristics of the paper. To that end, it has been envisaged that trivalent cationic salts are added, metered into the slurry or in the process for obtaining starch in powder form or by mixing a percentage of trivalent salts in powder form with the starch in powder form, seeking the solution of said salts in the slurry, so that they dissolve during the dispersion of the slurry in the process for obtaining the sheet of paper. Organic polymers such as polyacrylamides, polyvinylamides and polydadmacs could optionally be applied in addition to said salts.

  • Patent number: 8834678
    Abstract: The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. The tissue products also have a sizing agent that increases the Wet Out time, without negatively impacting softness or machine runability. Preferably the creping composition comprises a cationic component and a film forming component, both of which are preferably water soluble. The cationic component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained on the sheet. The overall retention of the creping composition on the sheet reduces the concentration of the composition in the machine process water, improving machine operability and runability.
