Dextrin binder composition for heat resistant non-wovens
InactiveUS20050215153A1Maintain strengthHigh hot tensile strengthNon-fibrous pulp additionStarch adhesivesPolyolCarboxylic acid
A polycarboxy binder composition that contains a dextrin as a co-binder is provided. The dextrin co-binder may be a dextrin, a modified dextrin, a maltodextrin, or combinations thereof. The dextrin may be chemically modified. A pre-binder composition is formed that contains a polycarboxy polymer, a crosslinking agent, and optionally a catalyst. The polycarboxy polymer may be a homopolymer or copolymer prepared from unsaturated carboxylic acids and may be modified to contain one or more vinyl compounds. The crosslinking agent may be a polyol that contains at least two hydroxyl groups. The pre-binder composition may be formed by admixing the polycarboxy polymer, the crosslinking agent, and optionally, the catalyst, in a mixing device. Dextrin may be added to the pre-binder composition in an amount of from 10-75% of the total binder composition. The dextrin binder composition may have a ratio of from approximately 90:10 to 25:75 pre-binder:dextrin co-binder.

Compositions used in manufacturing articles having an inorganically filled organic polymer matrix
InactiveUS6090195AReadily and inexpensively mass producedHigh strengthClosure lidsWrappersFiberPolymer science
Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, such as by heating to remove water by evaporation, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

Methods for dispersing fibers within aqueous compositions
InactiveUS6379446B1Quantity maximizationMinimize interstitial spaceNon-fibrous pulp additionProtein adhesivesFiberSolid component
Compositions and methods in which dry-committed fibers are substantially homogeneously dispersed throughout a fibrous composition. The fibrous composition is characterized as having sufficient yield stress and viscosity such that the shearing forces from the mixing apparatus are effectively transferred down to the fiber level. This is accomplished by means of an appropriate thickening agent, e.g, gelatinized starch. The dry-committed fibers are exemplified by flash dry fibers or fibrous sheets that have been cut or torn into fragments less than 2 cm across. Providing fibers that have been dry-committed greatly reduces the time that it takes to obtain substantially homogeneous dispersion of the fibers throughout the fibrous composition. This, in turn, reduces the risk of mixture spoilage and mechanical or chemical damage to the solid components within the fibrous composition.

A new method to produce formulations of bacterial cellulose that exhibit improved viscosity-modifying properties particularly with low energy applied to effectuate viscosity changes therewith is provided. Such a method includes the novel co-precipitation with a water soluble co-agent that permits precipitation in the presence of excess alcohol to form an insoluble fiber that can than be utilized as a thickener or suspension aid without the need to introduce high energy mixing. Such bacterial cellulose properties have been available in the past but only through highly labor and energy intensive processes. Such an inventive method as now proposed thus provides a bacterial cellulose-containing formulation that exhibits not only properties that are as effective as those for previous bacterial celluloses, but, in some ways, improvements to such previous types. Certain end-use compositions and applications including these novel bacterial cellulose-containing formulations are also encompassed within this invention.
