摘要： A nonwoven filtration fabric is composed of a plurality of fiber components of dissimilar denier and length which are evenly intermingled and bonded together in a sheet, including a first fiber component of staple polyester fibers of high denier and a textile length, a second fiber component of staple polyester fibers of low denier and shorter length than the first fiber component, a third fiber component of wood pulp fibers of shorter length than the first fiber components, and a suitable binder. The fabric is formed by a wet laid process in which the dissimilar fiber components are evenly mixed and distributed in a homogeneous slurry. A filter media made of the fabric has a high tensile strength, even pore size and distribution, low pressure drop, and is suitable for macrofiltration applications, such as filtering milk.

摘要： A cleaning cloth is formed by treating a fibrous material with a composition to which solid particles adhere. The composition includes a tackifier, a pressure-sensitive adhesive and a slip agent. The tackifier is 45-77 wt. %, the pressure-sensitive adhesive is 20-40 wt. % and the slip agent is 3-15 wt. % of the composition. Other ingredients, such an antifoam agent and a pH control, can also be added. The tackifier is an unsaturated, low-molecular-weight resin having low vapor pressure and a molecular weight of

摘要： An improved coversheet material for use in multi-layer boards. The improvement comprises a layer of continuous filament and a layer of fibrous web. The fibrous web is a blend of thermoplastic fibers. The thermoplastic fibers are high melt point fibers and low melt point fibers. The layer of continuous filament and the layer of fibrous web are bonded together by passing the layers between a pair of heated rolls which are under pressure. As the heat from the rolls melts the low melt point fibers, the pressure exerted on the rolls puts the melted fibers into contact with the high melt point fibers and the layer of continuous filament. As the melted fibers cool they secure themselves, the high point fibers and the continuous filament layer together to form an integral structure. The continuous filament provide strength to the coversheet material while the high melt point fibers in the fibrous web provide compatability with core materials used in a multi-layered board. This compatability permits the high melt point fibers to bond to the core material.
