A relofted, spunbonded nonwoven web exhibiting a solidity of from less than 8.0%, to at least 3.0%, and exhibiting a Quality Factor of at least 0.30. Methods of making a relofted web; and, methods of using a relofted web as an air-filtration web, e.g. as a filter media or a layer thereof.

There is provided a plain-weave fabric excellent in low air permeability and waterproofness. Further, there is provided a stent graft excellent in low water permeability mechanical properties and catheter storage capacity, including the plain-weave fabric as a graft substrate. A plain-weave fabric woven by interlacing weaving yarns in warp and weft, in which weaving yarns YA and YB arranged in the same direction have different crimp ratios A and B, respectively, a relationship thereof satisfies Formula 1, and the crimp ratio B is 4% or more, and the plain-weave fabric is preferably used for a stent graft; AB1.2.

A method of making a pile fabric that closely resembles natural sheepskin fleece, that includes forming a yarn made with wool fibers and non-wool fibers and knitting the yarn to form a pile fabric and knitting a scrim to form a base, while simultaneously knitting the yarn and the scrim together, where the yarn is attached to and extends from the scrim to form a length of pile fabric having a fiber side with natural wool fibers and non-wool fibers and the scrim on an opposing side. The method includes finishing the pile fabric as natural sheepskin, including, polishing the fiber side of the pile fabric, and cutting the wool fibers to a designated length.

A method of making a sheared wool, deep pile fabric that closely resembles natural sheepskin fleece, that includes forming a yarn made from wool fibers and simultaneously knitting the yarn and a scrim together, where the yarn is attached to and extends from the scrim to form a length of wool pile fabric having natural wool fibers on one side and the scrim on an opposing side. The method includes finishing the wool pile fabric as natural sheepskin by polishing the wool fiber side of the pile fabric by guiding the length of pile fabric over plural heated polishing rolls, where at least two of the plural heated polishing rolls rotate in opposite directions, and cutting the wool fibers to a designated length.

In an embossing apparatus, an embossing die includes a concavo-convex shaped molding unit. The molding unit is in contact with a front face of a base material. An embossing receiving die includes an elastic unit made of resin. The elastic unit is in contact with a back face of the base material. In the molding unit, a height difference (H) between a top portion of a convex portion and a bottom portion of a concave portion is a first value. In the elastic unit, a surface which forms an outer surface of the embossing receiving die is a smooth surface. In the elastic unit, a thickness (T) in a direction perpendicular to the outer surface of the embossing receiving die is a second value equal to or greater than the first value. The embossing die and the embossing receiving die sandwich the base material between the molding unit and the elastic unit.

A sheet manufacturing apparatus has a heating/compressing unit configured to form a sheet by heating and compressing material including fiber and resin, and the heating/compressing unit includes a first rotating body that rotates, and a second rotating body that rotates in contact with the first rotating body. The sheet manufacturing apparatus holds, heats, and compresses material by the first rotating body and the second rotating body. The sheet manufacturing apparatus includes a heating unit that heats the outside surface of at least one of the first rotating body and second rotating body.
