Abstract:
Disclosed herein are embodiments of a multi-layer nonwoven fiber material, and related methods of manufacturing the material. In one exemplary embodiment, the fiber material includes a first layer of directionally aligned fibers together with a second layer of randomly dispersed fibers dispersed over the first layer. Consistent with one exemplary method for manufacturing a nonwoven fiber material, the method includes dispersing a first plurality of fibers horizontally in one or more predetermined directions, as well as dispersing a second plurality of fibers horizontally in random directions. In such an embodiment, the second plurality of fibers is dispersed over the first plurality of fibers. Moreover, an exemplary embodiment of a roofing shingle employing a nonwoven fiber material as described herein is as disclosed.
Abstract:
A targeted elastic laminate material includes a plurality of elastomeric strands positioned attached to a first facing layer. A carrier layer having a width narrower than a width of the first facing layer is attached to the first facing layer. At least one of the elastomeric strands is directly attached to the first facing layer adjacent to the carrier layer. At least another of the elastomeric strands may be directly attached to the carrier layer. A second facing layer may also be attached to the first facing layer with at least a portion of the carrier layer positioned between the two facing layers, and at least one elastomeric strand directly attached to both facing layers. Additionally, multiple elastomeric strands may be directly attached to the first facing layer adjacent to opposite longitudinal edges of the carrier layer. A disposable garment may utilize the targeted elastic laminate material to include an area of elasticized gathering under tension to better conform to the body of the wearer. The invention also includes a method of making the targeted elastic laminate material.
Abstract:
A disposable wipe-out sheet 1 includes a plurality of long fibers 25 bonded to a heat-sealable base sheet 10 by sealing lines 9. The long fibers 25 includes groups continuously extending between each pair of the adjacent sealing lines 9 to form bridge-like portions and groups severed in two sections between each pair of the adjacent sealing lines 9 so as to fluff upward on the base sheet 10.
Abstract:
A method of preparing a reinforcing structure for use in manufacture a pultruded part where the reinforcing structure is pulled through a pultrusion die in a continuous longitudinal pull direction. The method includes arranging a plurality of first reinforcing fibers in a transverse direction and attaching a permeable transport web of staple fibers to the first reinforcing fibers such that the portion of the first reinforcing fibers oriented in the direction transverse comprises at least 40% of a volume of materials comprising the reinforcing structure.
Abstract:
A patterned pile fabric of stitch-bonded construction. The fabric includes a substrate layer with an arrangement of ground yarns extending in stitched relation through the substrate layer so as to define a ground covering across the substrate layer. An arrangement of pile forming yarns extend in stitched relation through the substrate layer such that the pile forming yarns define a patterned arrangement of looped elements projecting away from the ground covering in predefined three dimensional patterned arrays disposed across the fabric.
Abstract:
A composite sheet comprises a nonwoven fabric and a rubber elastic material bonded onto the nonwoven fabric. The nonwoven fabric has nonelastic fibers aligned in one direction and has elongation of 100% or higher in a direction perpendicular to the aligned direction of the nonelastic fibers. The rubber elastic material is bonded to the nonwoven fabric in a pattern having orientation perpendicular to the aligned direction of the nonelastic fibers.
Abstract:
A hot melt adhesive composition is based on an isotactic polypropylene random copolymer (RCP). The composition contains about 4%-50% by weight of the RCP copolymer, about 20%-65% by weight of a compatible tackifier, about 0%-40% by weight of a plasticizer, about 0%-3% by weight of a stabilizer, about 0%-40% by weight of a wax, about 0%-60% by weight of an atactic poly-null-olefin (APAO), and about 0%-40% by weight of a secondary polymer. The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.
Abstract:
A material is provided that is particularly suited for use in absorbent articles. The material has a base layer of a generally non-elastic material and at least two strips or regions of elastomeric material attached to the base layer material with a space therebetween such that a center region of the base layer material is bordered on at least two sides by composite regions of the elastomeric materials and the base layer material. The center region of base layer material remains generally non-extensible and the composite regions are stretchable in at least a first direction as a result of tensioning and necking-in the base layer material prior to attaching the elastomeric materials. The invention includes methods for making the material, as well as absorbent articles incorporating the materials.
Abstract:
A laundry-durable stretchable composite fabric, based on two nonwoven outer layers and a pre-stretched inner layer of elastomeric fibers of at least 400 decitex and at least eight threadlines/inch, and having a flat surface appearance, is provided.
Abstract:
Paper machine clothing, especially a press felt (1), has a support (2) which has at least one layer of a thread lap (3, 4, 5, 13). The lap threads (6, 7, 8, 9, 10, 14, 17, 21, 25, 26, 27, 28, 33, 38, 43, 44, 45) run parallel to one another. Spacing threads are present which run between two lap threads (6, 7, 8, 9, 10, 14, 17, 21, 25, 26, 27, 28, 33, 38, 43, 44, 45) and are soluble in a solvent in which the remaining part of the paper machine clothing (1) is not soluble.
