Abstract: A breathing device 10 for purifying a user's breath includes a snorkel 12 and a canister 18 in fluid communication with the snorkel. A plurality of fiber layers 28 each treated with a breath deodorizer one or more canister discs 26 separating two of the fiber layers, and a discharge hole 42 in the canister generally opposite the canister input end.

Abstract: A size composition containing one or more film forming agents, at least one coupling agent, and a fatty amide lubricant synthesized from a (poly)ethylene amine and a C5-C20 unsaturated fatty acid is provided. The fatty acid is preferably a conjugated fatty acid and the (poly)ethylene amine is preferably tetraethylenepentamine. The fatty amide lubricant may be modified by maleinized rubber or carboxylated rubber. The size is advantageously applied to glass fibers such as wet use chopped strand glass and used to form roofing composites, such as shingles. The fatty amide lubricant facilitates interfacial bonding between the glass and asphalt through a vulcanizing mechanism. The unsaturation of the fatty amide modifies the surface energy of the glass fibers to make the glass more compatible with the asphalt, enhances the compatibility between the glass and the asphalt, and improves glass/asphalt interactions through the reduced interfacial tensions.
