Abstract: Dual glass fibers can be processed into coherent webs and felts by first blending the dual glass fibers with an equal or greater amount of uncrimped fibers. Optionally, other crimped fibers can be added without significant impact on processibility.
Abstract: The heat-resisting material according to the present invention comprises a fiber aggregate containing crystalline alumina short fibers and formed in a continuous length and an inflammable sheathing for maintaining the shape of the fiber aggregate in a compressed state. The expansion percentage of the fiber aggregate after burn-off of the sheathing is not less than 10% by volume based on the volume of fiber aggregate in a compressed state. This heat-resisting material can be worked into various forms of product of the heat-resisting material such as rope, square bar, sheet, etc., according to the purpose of use. The present heat-resisting material is provided in continuously long products, has high heat resistance and restoring property, and can be easily applied to the openings or spaces ranged continuously in the longitudinal direction, such as the boundaries between the blocks of the heat-resisting material and joints.

Abstract: The blood absorbence properties, e.g., free swell blood absorbence capacity and after load blood absorbence capacity of superabsorbent materials is enhanced by combining the superabsorbent materials with enhancing agents which serve to enhance the blood absorbent properties thereof. The enhancing agents can be applied to the superabsorbent materials or they can be provided on a fibrous material to be combined with the superabsorbent materials. The enhancing agents are selected from materials that include functionalities that allow them to hydrogen bond to the superabsorbent material when the enhancing agent is applied directly thereto or combined with materials to which the enhancing agents have been applied.

Abstract: A papermaker's fabric is provided having a spun bonded reinforcement. A layer of spun bonded material may be placed in any one of a number of possible locations in the fabric, depending upon the felt stratification desired. For example, it may be attached to the upper surface (or paper contacting side) of the base fabric layer; to the lower surface (or machine contacting side) of the base fabric layer; between two base fabric layers, in the case of a laminated felt; between layers of fibers; or in any other desired location. The spun bonded material may be attached through the use of needling or by use of adhesives, low melts, or ultrasonic methods.
Abstract: A patterned fibrous web and a process for making the patterned fibrous web are disclosed. The patterned web includes a plurality of functional particle-loaded areas forming a pattern of functional particles. Beneficially, when cut, the patterned fibrous web does not release functional particles from the cut edges.
