Abstract: Aspects herein are directed to a composite nonwoven textile suitable for use in apparel and other articles that are resistant to pilling. The composite nonwoven textile may be finished by one or more of applying a chemical binder to a first face of the composite nonwoven textile and forming thermal bonding sites. The chemical binder and the thermal bonding sites help to secure fiber terminal ends and minimize the formation of pills.

Abstract: An insulated fiberfill comprises a first fiber layer and a second fiber layer. The first fiber layer comprises an inner surface and multiple connecting portions arranged on the inner surface and spaced from each other. The second fiber layer is mounted on the inner surface, and comprises multiple joining portions respectively connected with the connecting portions and multiple folding portions inclined toward a same direction. Each of the folding portions is formed between two adjacent joining portions, leans against an adjacent folding portion, and covers at least one of the joining portions. Accordingly, the insulated fiberfill is beneficial for enhancing the capability of the coat and sleeping bag to keep the human body warm. Also, the fabricating steps of the coat and sleeping bag are simplified, and the fabricating time of the same is shortened.

Abstract: An insulated article that changes its fill power through adjustment in displacement is provided. Outer and inner surfaces of a folded web consisting of slanting lapped continuous filaments tow band are attached with an outer shell fabric and a lining fabric made of nonwoven or cloth, respectively. This forms a sandwich structure similar to the birds' down feathers underneath the contour feathers. By adjusting the horizontal displacement between the outer and lining fabrics, the fill power (or fluffiness) of the folded web can be changed. Thus, the present invention is applicable to products such as sleeping bags, duvets, snow suits, snow boots and the like. It also has sound and heat proof properties as well as better thermal insulation.

Abstract: An insulation material structure having crimped continued filaments interposed between staple fiber webs. Crimped continued filament web is interposed between an upper and lower natural or synthetic staple fiber webs having low melty fibers therein. After subjecting to cross-laid lamination-forming process and thermal setting, a resilient, composite laminated layered structure is formed. The laminated layer structure is subsequently cut, sewed, and stitched onto the facing and lining fabrics located at the upper and lower layers to form a stretchable insulation material structure having multiple fiber layers.

Abstract: Improved batts for sleeping bags, insulated apparel, bedding, and other uses are made from a tow of crimped continuous filaments by a machine and process which spreads, extends, and wraps the tow into an endless flat-tube structure with desired uniformity, balanced tensile strength, dimensional stability, stretchability, and high loft.

Abstract: The present invention relates to a fibrous pad structure having a variable density. The continuous strip-shaped webs are sliced and rubbed to form one or more continuous strip-shaped webs that are separated from each other by a constant distance. The strip-shaped webs can also be spread and lapped onto a continuous smooth fibrous web in a regular arrangement. The combined fibrous webs are corrugated and shaped into a vertical porous fibrous pad. Such a fibrous pad has a different density distribution in the transversal cross section and a continuous corrugated structure in the mechanical direction. The density of the combined fibrous pad in accordance with the present application can be adjusted according to the uses of the fibrous pad. The mechanical properties of the products made from the fibrous pad thus are adjustable to meet the requirements of different uses of the product.

Abstract: The present invention relates to a air permeable porous fiber pad and a method for making a air permeable porous fiber pad. A single-layer or multi-layer web may be cut by at least two sets of belt rollers, thereby forming strip-shaped webs whose width is the same as the belt. The at least two sets of belts may divide the parallel juxtaposed strip-shaped webs into spaced layers. At least two sets of rollers whose center of shaft is adjustable may be used to adjust the position of each layer of strip-shaped web, so that the layers of strip-shaped webs may overlap each other, and the overlapped layers of strip-shaped webs may be conveyed into a crosslapper, thereby making a air permeable porous fiber pad.

Abstract: A corrugated fiberfill structure is provided including at least one fibrous web folded to form a plurality of pleats having alternating crests and bases, each of the pleats having a pair of legs in which each of the legs has a first leg surface and a second leg surface, the first leg surface of one leg being in intimate contact with the first leg surface of an adjoining leg of the pleat and the second leg surface of the one leg being in intimate contact with the second leg surface of one adjoining leg of an adjacent pleat over a portion of each leg. At least some crests define a first structural surface and at least some bases define a second structural surface; with the distance between the first and second structural surfaces defining the thickness of the structure. The pleats of the structure are so arranged across the thickness that the density of the structure varies between the first and second structural surfaces.

Abstract: A method is provided for forming a corrugated structure from a fibrous web by first forming a fibrous web; alternatingly lapping the fibrous web; folding the fibrous web to form corrugations; brushing fibers from one corrugated peak to extend to an adjacent peak and bridge the gap therebetween; spraying resin on the corrugated fibrous web; heating the resin-sprayed corrugated fibrous web; or further sandwiching said fibrous web with a pair of outer webs with resin sprayed thereon and heating said sandwiched fibrous web. Another embodiment initially combines fibers of low melting point with regular fibers and heats the corrugated fibrous web after brushing, rather than spraying resin on the corrugated fibrous web.
