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.
