摘要： 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. The reinforcing cellular pattern may be embossed above said absorbent fibrous substrate or may be substantially co-planar with said fibrous substrate. The composite substrate may also be backed with a liquid impervious layer, either as a separate layer applied thereto the bottom surface, or as an applied coating. The liquid impervious surface may be usefully selected with a high co-efficient of friction to provide a non-skid surface.
摘要翻译：本发明提供一种具有多个不连续单元的吸液性纤维基材，其中设置有第二材料。该第二材料选自多种有机或无机固体，其可提供增强效果，使得防止锋利的仪器通过新的复合结构。增强材料以细胞形式以不连续的阵列布置在纤维基质中，从而为液体吸收到所述纤维基质中提供途径，同时所述增强材料提供对尖锐边缘器械的穿透抵抗力。当以这种方式设置时，由于增强材料不以连续图案设置，因此保持柔性。优选地，所设置的图案没有提供用于锋利边缘的连续穿透线的线性区域。更优选地，图案被设计为将所述线性区域约束到基本短的长度的互锁形状的图案。增强细胞图案可以在所述吸收性纤维基材上方压花，或者可以与所述纤维基材基本共面。复合衬底也可以用液体不可渗透层支撑，或作为施加到其底表面上的独立层，或作为施加的涂层。液体不可渗透的表面可以有效地选择具有高的摩擦系数以提供非滑动表面。

摘要： 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.

摘要： 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 ft2, 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. It is also preferred that the sheet material exhibit an absorbent efficiency of at least 0.2, a cut-resistance at least 30 kgf/cm, a wet abrasion loss of less than about 400 mg/100 revolutions, and a dry abrasion loss of less than about 300 mg/100 revolutions.
