Abstract: The present invention relates to a press-heating gas grafting hydrophobization apparatus, and a hot water-resistant paper and an oil-absorbing paper manufactured using the press-heating gas grafting hydrophobization apparatus. In the press-heating gas grafting hydrophobization apparatus according to the present invention, since a non-air-permeable dryer belt is provided surrounding and pressing a drying roller to prevent dissipation from a base material of a fatty acid chloride vaporized by the drying roller, the press-heating gas grafting hydrophobization apparatus has an advantage of improving efficiency of a gas grafting reaction. Therefore, by using the press-heating gas grafting hydrophobization apparatus according to the present invention, the reaction amount of fatty acid chloride per unit area can be remarkably improved.

Abstract: Disclosed are single ply creped webs and products made therewith. The webs and products are generally durable, flexible In and highly dispersible. For example, the creped single ply tissue products have a Slosh time less than 1 minute, and more preferably less than about 30 seconds, and a wet cross-machine direction (CD) tensile strength greater than about 100 g/3?. The foregoing properties are achieved even in those instances where the products comprise a latex binder disposed on an outer surface. For example, the tissue products may be produced by a print crepe process that disposes a non-crosslinked latex binder on at least one of the product's outer surfaces.

Abstract: The present invention relates to a cellulosic fiber of the lyocell genus. The fiber according to the invention has the following properties: a) the fiber has a content of hemicellulose of 5 wt. % or more b) the fiber is characterized by the Hoeller factors F1 and F2 as follows: Hoeller factor F1?0.7+x and ?1.3+x Hoeller factor F2?0.75+(x*6) and ?3.5+(x*6) wherein x is 0.5 if the fiber does not contain a matting agent and x is 0 if the fiber does contain a matting agent, and if x is 0.5, the fiber is essentially free from any incorporation agent.

Abstract: Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable and dispersible. The products generally have a Slosh time less than 2 minutes, such as less than about 60 seconds, such as less than about 45 seconds. Surprisingly, the foregoing Slosh times are achieved despite the tissue products having relatively high cross-machine direction (CD) wet tensile strength, such as greater than about 100 g/3?. Typically, increasing wet tensile strength, particularly wet CD tensile strength, negatively effects dispersability and increases Slosh time. Despite this trend, the present invention surprisingly provides a tissue product having a relatively high degree of wet strength and good dispersability.

The resulting PVA paper substrate is biodegradable, of food-grade quality, and resistant to water and grease, with a grease resistance higher than or equal to that corresponding to kit No. 6 in a TAPPI T559 pm-96 standard test.

Abstract: Methods for forming multi-layer substrates including top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material includes polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F.-350° F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.
