The blended padding of the present disclosure includes a polyester fiber and a water-repellent regenerated cellulose fiber treated in a specific manner. The water-repellent regenerated cellulose fiber contains, for example, a water-repellent rayon, and the polyester fiber contains, for example, at least one fiber selected from the group consisting of a polyethylene terephthalate (PET) fiber, a polytrimethylene terephthalate (PTT) fiber, a polybutylene terephthalate (PBT) fiber, a polyethylene naphthalate (PEN) fiber, a polylactic acid (PLA) fiber, a polycaprolactone (PCL) fiber, and a polybutylene succinate (PBS) fiber.

Aspects herein are directed to a composite nonwoven textile having at least a first entangled web of fibers, a second entangled web of fibers, and an elastomeric layer positioned between the first and second entangled webs of fibers. The composite nonwoven textile includes different features including one or more debossed portions and one or more pleated constructions.

A carbon fiber nonwoven fabric sheet 15 contains discontinuous carbon fibers. The carbon fiber nonwoven fabric sheet 15 is an elongated parallel web 14 in which two or more rectangular fiber webs 10 having carbon fibers oriented substantially in one direction are stacked in the same direction with their end portions shifted from each other. With a method for producing the same, a fiber web is formed by opening discontinuous carbon fibers using a carding machine, and orienting the carbon fibers substantially in one direction, rectangular fiber webs 10 are formed by cutting the fiber web in a width direction or an oblique direction, an elongated parallel web 14 is formed by stacking the rectangular fiber webs 10 on each other with their end portions shifted from each other, and a carbon fiber nonwoven fabric sheet 15 is obtained by cutting both ends of the elongated parallel web 14. A carbon fiber reinforced resin molded body according to the present invention contains the carbon fiber nonwoven fabric sheet and a matrix resin. As a result, the present invention provides a carbon fiber nonwoven fabric sheet that can be used in the same manner as that for a uniaxial sheet constituted of a continuous carbon fiber sheet, a method for producing the same, and a carbon fiber reinforced resin molded body.

The present invention provides compositions comprising aligned fibers of electrospun PNIPAAm and poly (?-caprolactone) (PCL) (denoted PNIPAAm/PCL fibers). The PNIPAAm/PCL compositions enable enhanced growth and detachment of intact anisotropic cell sheets. The compositions do not require chemical modification or resource-intensive techniques, thus saving time and expense, and have the potential to generate tissue-specific, aligned cell sheets for transplant studies.

A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.

A method to prepare nonwoven webs suitable for use as an industrial wipe which have good MD and CD strength is provided. The method includes hydroentangling an airlaid web of natural cellulose fibers having a fiber length of no more than 3.5 mm, bonding fibers having a fiber length of from 6.0 to 12.0 mm and optionally, manmade fibers having a fiber length of from 6.0 to 12.0 mm. The airlaid web is a homogeneous mat of the natural cellulose fibers, the optional manmade fibers and the bonding fibers and is not laid on a precursor web. No non-fiber adhesive or binder is utilized. The airlayering and hydroentangling are conducted in a continuous operation. The method to manufacture the nonwoven web may include an embossing or crepeing operation.

The present invention relates to a multi-layered composite material manufactured by thermocompressing a multi-layered sheet, comprising: a first sheet layer formed from a solution containing nanofibrillated cellulose and a first thermoplastic matrix polymer; and a second sheet layer formed from a solution containing a second thermoplastic matrix polymer. The multi-layered composite material of the present invention has the high strength and high elastic modulus.

The present invention is generally related to a high capacity, high efficiency nonwoven filtration media comprising a gradient pore structure. In particular, the filtration media can comprise thermoplastic synthetic microfibers, fibrillated fibers, staple fibers, and a binder. Furthermore, the filtration media may be produced without the use of glass fibers or microglass fibers. Consequently, the filtration media of the present invention does not cause the same issues as conventional filtration media that comprises glass fibers and/or microglass fibers. Moreover, the filtration media can be used to treat fuel, lubrication fluids, hydraulic fluids, and various other industrial gases.
