Abstract: Heat activated, fabric conditioning products comprising a thick, absorbent substrate impregnated with fabric-conditioner chemicals are suitable for use at elevated temperatures encountered in laundry dryers. Prior to being used, such products tend to be stiff and boardy because of the brittle, wax-like properties of the fabric conditioner chemicals at ambient temperature. The stiff, boardy properties are substantially eliminated by temporarily compressing the thick impregnated substrate to less than 70% of its original thickness.

Abstract: Creping of fibrous webs to enhance their softness and bulk is improved and the resulting creped web is made strong, water dispersible and non-blocking by employing a bonder and creping adhesive composition containing four components which are blended to produce a mixture having a percent solids of from 10% to 40% and an initial modulus for a film of the solids of less than 1.75 .times. 10.sup.8 dynes/cm.sup.2. The composition (mixture) functions as a bonder for the fibers to impart strength and as a creping adhesive for the web so that creping enhances softness and bulkiness. Also disclosed are methods of creping employing such a bonder and creping adhesive composition and sheet materials creped with such compositions.

Abstract: A solution for treating metal surfaces is provided which is capable of cleaning (degreasing) and hydrophilically sensitizing the metal surface. The treatment solution is a synergistic improvement over conventional silicate treating solutions obtained by the addition of the ferric chelate of ethylene diamine tetra acetic acid (Fe.sup.+.sup.3 EDTA).

Abstract: A peroxidic-initiated graft copolymerization process wherein a water-insoluble thiocarbonated or thiocarbamated substrate is exposed to high-frequency microwave energy in the presence of at least one ethylenically unsaturated monomer and a perioxidic free radical initiator.

Abstract: Fiber containing devices for eliminating mist and/or particulate matter from flue gases may become plugged with carbonaceous and/or inorganic deposits or particulate matter. Cleaning of such mist eliminators to remove the plugging deposits is accomplished by the present invention by employing a two-step cleaning process. The process involves soaking the plugged fiber beds of the mist eliminator in hot acidified potassium permanganate (KMnO.sub.4) followed by treating the beds with gaseous sulfur dioxide.
