A paper suitable for use in a battery or battery pack as a flame barrier or thermal insulation, the paper comprising 60 to 95 weight percent aerogel powder and 5 to 40 weight aramid polymer fibrils; the paper having a thickness of 50 to 4000 micrometers.

A method for monitoring hydrophobic particles contained in a pulp suspension, includes obtaining a sample from a pulp suspension or a filtrate of the pulp suspension. A fluorescent dye is added to the sample to stain particles in the sample. The sample is fractionated to obtain at least a first fraction and a second fraction, wherein the second fraction is a fiber fraction. The method includes for the obtained fractions, fluorescence emitted by the particles in the fractions, calculating an integral of the fluorescence measured for the fractions excluding the fiber fraction, and correlating the calculated integral of the fluorescence to the amount of acetone soluble material in the pulp suspension, and optionally measuring light scattering signal of the particles in at least first and second fractions.

A binding material to obtain a molded body by binding fibers to each other, includes a thermoplastic resin and a fluorescent whitener, and the fluorescent whitener has a melting point higher than a fusing point of the thermoplastic resin. The melting point of the fluorescent whitener is preferably 200° C. or more. A content of the fluorescent whitener in the binding material is preferably 1.0 percent by mass or less. The binding material preferably further includes a white pigment.

The present disclosure relates to fibrous structures including active agents and having a graphic printed thereon. In some embodiments, a nonwoven web may include a fibrous structure comprising filaments. In turn, the filaments may include filament forming material, and an active agent releasable from the filaments when exposed to conditions of intended use. In addition, a graphic may be printed directly onto the fibrous structure.
