Abstract:

A multi-purpose sheet material comprising an absorbent layer and a cut-resistant material in contact with the absorbent layer. The cut-resistant material can comprise a cut-resistant support system, such as cut-resistant support element formed in the absorbent layer for example. The cut-resistant material may alternatively comprise cut-resistant particles, such as polymer particles having an average size of at least about 100 micrometers for example. Preferably, the sheet material exhibits an absorbent efficiency of at least about 0. 2 and a slice resistance of at least about 30 kgf/cm, and more preferably an absorbent efficiency of at least about 1. 0 and a slice resistance of at least about 40 kgf/cm. It is also preferred that sheet material exhibit a cut-resistance of at least about 30 kgf/cm, an absorbent efficiency of at least about 0. 2, and a wet abrasion loss of less than about 400 mg per 100 revolutions.

US Classification:

Abstract:

The present invention provides a liquid absorbent fibrous substrate having a plurality of discontinuous cells in which a second material is disposed. This second material is selected from a broad variety of organic or inorganic solids which may provide a reinforcing effect such that a sharp instrument is prevented from passing through the new composite structure. The reinforcing materials are disposed in a discontinuous array, in a cellular form in the fibrous substrate thus providing a path for liquids to be absorbed into said fibrous substrate, while said reinforcing materials provide resistance to penetration by sharp edged instruments. When disposed in this manner, flexibility is maintained since the reinforcing materials are not disposed in a continuous pattern. Preferably, the pattern disposed is free of linear regions that provide a continuous line of penetration for sharp edges. More preferably, the pattern is designed with a pattern of interlocking shapes which constrain said linear regions to essentially short lengths.

US Classification:

428323, 428326, 428327, 428340, 428409, 264122, 264125

Abstract:

A cut-resistant and shred-resistant absorbent sheet material including an absorbent substrate and cut-resistant particles distributed through the substrate. Preferably, the absorbent substrate comprises cellulosic material and the particles comprise polymeric materials having an average size of at least about 100 micrometers, and most preferably between 100 and 1000 micrometers. It is also preferred that the absorbent substrate is provided in an amount of at least 50 percent by weight and is substantially free of inorganic free filler particulate. In addition, it is preferred that the sheet material has a basis weight of at least 100 pounds per 3000 ft , and that the particles are provided in an amount of between about 10 percent and about 50 percent by weight of the sheet. The sheet material can be made using typical paper making processes. Preferably, heat and/or pressure are applied to the sheet material to cause the particles to at least partially flow, so as to bond to the absorbent substrate.

International Classification:

F26B 3/30
F26B 3/10

US Classification:

392413, 392417

Abstract:

A novel flexible infrared device is provided for heating surfaces in a uniform manner not available previously. The heater is designed in a manner so as to allow “hugging” of the surface by attaching the heater module to at least two swivel points located above the heating plane. In this manner the common problems encountered with heating dies by IR heaters is overcome.
