Abstract:
An engineered textile includes a plurality of yarn strands with a subset extending in a substantially parallel and spaced arrangement and a bonding material extending across the plurality of yarn strands. The bonding material encapsulates a portion of each yarn strand to bond adjacent ones of the plurality of yarn strands together.
Abstract:
Knit apparel formed using knitted structures and yarn content to create zonal venting and material standoff are provided. In aspects, garments having standoff structures knitted into one or more zones within the garment, on an internal and/or external surface of the garment, include tops and half-tights. The standoff structures are created using missed stitches with floats adjacent knitted stitches are integral to the surrounding material. Additionally, garments having airflow apertures are included, with transfer-stitch structures creating integral openings within the surrounding material.

Abstract:
Provided are a filter medium for an air filter capable of having extended life even when composed of embossable material. The filter medium (1) has a tensile elongation of 10% or greater, and includes a main collection layer (30) having a filing rate of 5% to 15%, a thickness of 0.35 mm to 0.70 mm, and a peak in a fiber diameter distribution at less than 1.0 μm and a peak at 1.0 μm or greater. An average fiber diameter of small fiber diameters of less than 1.0 μm is from 0.1 μm to less than 0.8 μm, and an average fiber diameter of large fiber diameters of 1.0 μm or greater is from 1.2 μm to less than 3.0 μm. A volume ratio of the fibers having the small fiber diameter to the fibers having the large fiber diameter is from 30:70 to 80:20.
Abstract:
Various embodiments provide an apparatus, method, and/or system by which fiber, e.g., in the form of tow or tow, is used to create a shaped ply by facilitating drawing fiber from a supply along a fiber axis between two sets of pins; moving the pins across the fiber axis to form a fiber web in the desired ply shape; fixing the fiber web to form the shaped ply; and releasing the shaped ply. By enabling formation of shaped plies (including plies with doubly curved surfaces and simultaneous sequences of strategically shaped plies) directly from a single piece of fiber tow, various embodiments discussed herein enable substantial reductions in labor and materials costs that are conventionally associated with construction of composite preforms and accompanying composite products.

Abstract:
Provided is a flat fiber-reinforced plastic strand which is produced by curing a twisted resin-impregnated strand and has no disturbed fiber orientation, and a flat fiber-reinforced plastic strand sheet which is produced by using said flat fiber-reinforced plastic strands. According to a method of manufacturing the flat fiber-reinforced plastic strand 2, (a) a twisted resin-impregnated strand f2 in an uncured state, the strand including a plurality of reinforcing fibers f, is fed in a state of tension between a pair of heated steel belts 41A and 41B facing each other and making rotation movements; and (b) the resin-impregnated strand f2 is sandwiched and heated by the steel belts 41A and 41B, and pressurized from both sides of the strand f2 to form a cross section of the strand into a flat shape, and, with the shape being kept, a resin is cured and cooled.
Abstract:
Present invention relates to a process of forming a multi-layer pad of a non-woven fiber batt and a foam layer having conforming convoluted surfaces and to a multi-layer pad incorporating a non-woven fiber batt and foam layer. The process of forming a non-woven batt layer and a foam layer having conforming convoluted surfaces comprises transporting each layer along its longitudinal dimension while compressing each layer along its lateral dimension. Concomitantly with compression, each layer is cut transversely along its lateral dimension to separate each layer into an upper segment and a lower segment and to provide conforming convoluted surfaces on the segments of each layer, the convoluted surfaces comprised of upstanding projections and depressions. The convoluted surfaces of the non-woven batt layer and the foam layer are aligned so that the upstanding projections of the batt convoluted surface project into the corresponding depressions of the foam convoluted surface, while the upstanding projections of the foam convoluted surface project into the corresponding depressions of the batt convoluted surface.
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 30% of a volume of materials comprising the reinforcing structure.
