A pre-impregnated decorative base paper for decorative coating materials, comprising biopolymer nanoparticles.. . ... Ahlstrom Corporation

Laundry aid and use thereof

A dye-capturing laundry aid comprising: a support in the form of a sheet comprising water-insoluble fibers; a first substance anchored to the support, wherein the first substance has moieties that are cationic when exposed to water at one or more ph values in the ph range of from 6 to 10; and a second substance that coats the first substance, wherein the second substance is a polymer that remains substantially coated upon the first substance when the laundry aid is exposed to water over the ph range of from 6 to 10, and at least 50% of the repeating units in the polymer have a structure according to the following formula (1).. . ... Ahlstrom Corporation

High efficiency and high capacity glass-free fuel filtration media and fuel filters and methods employing the same

High efficiency and high capacity glass-free filtration media include a blend of synthetic non-fibrillated staple fibers and fibrillated cellulosic staple fibers, wherein the fibrillated cellulosic fibers are present in the media in an amount to achieve an overall filtration efficiency at 4 microns of 95% or higher and a ratio of filtration capacity to media caliper of 0.5 mg/in2/mils and greater. The filtration media is made by forming a wet laid sheet from a fibrous slurry blend of the synthetic non-fibrillated staple fibers and fibrillated cellulosic staple fibers, followed by drying the sheet to obtain the filtration media. ...
