Abstract: Methods of reducing paper dusting in a papermaking process, and a low dusting tissue having increased strength are provided. Application of a polymer comprising at least one amine-containing vinylic or allylic monomer to at least one surface of a paper web during the papermaking process reduces the dusting tendency of the paper, and increases both the wet and dry strength of the paper product.

Abstract: The disclosed systems and method for evaluating the integrity of media pads within an adiabatic cooling system includes at least one media compartment containing at least one media coupon that is representative of at least one of the media pads. The system is adapted to be fluidly coupled to a source of representative process water and to provide such water to the at least one media compartment. A source of airflow fluidly is also coupled to the at least one media compartment. The flow of representative process water and airflow to the media coupon within the media compartment simulates the operation of the adiabatic cooling system. The at least one media coupon may then be analyzed as representative of media pads within the adiabatic cooling system.

Abstract: A method of incorporating a low molecular weight polymer (e.g., polymer strength aid) into an industrial process (e.g., papermaking process) is provided. The method comprises treating an industrial process (e.g., paper sheet precursor) with a powder or wetted powder, wherein the powder comprises a polymer dry polymer (e.g., polymer strength aid), wherein the polymer dry polymer (e.g., polymer strength aid) has a weight average molecular weight of from about 10 kDa to about 2,000 kDa.
