摘要:
The invention provides methods and compositions for increasing the strength of a paper sheet. The method involves adding to the paper sheet an amine containing polymer. The amine containing polymer interacts with materials such as GPAM or starch to make the paper stronger in terms including tensile strength, surface strength and bulk strength.

The present disclosure is generally directed to a dispersible moist wipe comprising hydroentangled fibers and a binder composition. The moist wipe demonstrates high initial wet strength while maintaining effective dispersion in an aqueous environment. The moist wipe has potential application as a flushable surface cleaning product and/or a flushable cleansing cloth.
摘要:
A method for modifying the physical and/or chemical characteristics of a web of paper material includes the steps of causing a web of paper material, having a dry content between 1% and 90%, to adhere to an endless conveyor belt of elastic material, subjecting the conveyor belt and the web to at least one localized dimensional variation, and introducing at least one additive between the fibers of the web while adhering to the belt before or during the localized dimensional variation.

This invention relates to a paper substrate containing high surface sizing and low internal sizing and having high dimensional stability, as well as methods of making and using the composition
摘要:
A method including improving a property of a paper product precursor by adding a molten-wax suspension to a slurry including the paper product precursor, the molten wax suspension including a suspension of molten wax particles in a liquid solvent, the liquid wax particles being at a temperature higher than the melting point of the wax.
摘要:
A recording medium is provided, such as paper, secured by magnetic microwires. The recording medium comprises: a pulp structure formed by pulp fibers, said pulp structure carrying microwires having a metal core of a predetermined material composition, and an insulating layer coating on said metal core; and at least one coating layer on at least one side of said pulp structure. The pulp structure is a single-layer structure with the microwires fully embedded in said single layer, the microwires having cross-sectional dimensions approximately equal to cross-sectional dimensions of the pulp fibers.
摘要:
The present invention is related to a method of treating a material web in a paper or paper-board machine, in which method the moving web (1) is treated with a gas (2), particularly with steam. At least one supplementary treatment agent (3) is dosed into the stream of said gas and effected to travel along with said gas toward said material web. The invention also concerns an apparatus suited to implement the method.
