Latest Patents
One of Diehl's latest patents is focused on a latex binder for nonwoven fibers and the articles made therewith. This invention relates to a latex that can be utilized as a binder for nonwoven applications, specifically to form a permeable sublayer of personal hygiene articles. The latex is prepared through a detailed process that includes polymerizing a monomer mixture comprising styrene, itaconic acid, surfactant, and a water-soluble free radical initiator to form a seed. Following this, equal increments of a monomer mixture of styrene, butadiene, and acrylic acid are sequentially added to the seed under emulsion polymerization conditions to create a styrene-butadiene-acrylic acid copolymer. Finally, the copolymer is neutralized to a pH of about 4.5 to 7 to form the latex.
