A laminate has first and second spunbonded nonwoven layers at least one of which comprises or consists essentially of crimped continuous filaments that are bicomponent filaments having a first component based on polypropylene and a second component based on polypropylene. A specific density ρ (g/cm.sup.3) of the spunbonded nonwoven laminate depending on the surface density of the spunbonded nonwoven laminate lies below a density limit ρ.sub.G defined by the following equation:

ρ.sub.G=9 cm.sup.−1×surface density g/cm.sup.2+0.0393 g/cm.sup.3.

The present disclosure provides a laminated fabric structure comprising: a fabric layer; a nanofibrous membrane comprising a matrix of nanofibers; and a permeable adhesive layer sandwiched between the fabric layer and the nanofibrous membrane and comprising a filled portion and an unfilled portion. The permeable adhesive layer is able to combine the nanofibrous membrane and fabric layers together to provide significant protection on the nanofibrous membrane without sacrificing on the air permeability of the laminated fabric structure.

Provided is a thermal conducting sheet, including: a binder resin; insulating-coated carbon fibers; and a thermal conducting filler other than the insulating-coated carbon fibers, wherein the insulating-coated carbon fibers include carbon fibers and a coating film over at least a part of a surface of the carbon fibers, the coating film being formed of a cured product of a polymerizable material.

The present invention provides: a multilayer sheet which contains a polyolefin resin and carbon fibers, and which is highly competitive in price; and a method for producing this multilayer sheet. A multilayer sheet (100) according to the present invention comprises: a carbon fiber layer (20) which contains a woven fabric of carbon fibers; and polyolefin resin lavers (10) which are in contact with the both surfaces of the carbon fiber layer (20). The carbon fiber layer (20) has a porosity of 10.0% or less. A method for producing this multilayer sheet (100) according to the present invention comprises a process of applying a surface treatment agent to the both surfaces of a woven fabric of carbon fibers, a process of superposing polyolefin resin sheets on the both surfaces of the woven fabric to which the surface treatment agent has been applied, and a process of melting the polyolefin resin by applying a pressure onto the laminate of the polyolefin resin sheets and the woven fabric, while heating the laminate, and subsequently cooling the laminate, thereby obtaining a multilayer sheet.

A protective barrier having antimicrobial and antiviral properties. A filtration media structure is constructed from an inner media layer and an outer media layer. The inner and outer layers are spunbond and may be nonwoven or woven. An antimicrobial additive of silver and copper is compounded into a polypropylene base to form each of the layers. A middle layer of melt blown nonwoven filtration media layer may be encapsulated between the inner and outer media layers. The middle layer may also be constructed with the antimicrobial additive of silver and copper for enhanced antimicrobial protection. A channeling layer may also be sandwiched between the inner and outer media layers. The channeling layer comprises a plurality of filaments having a non-round or round cross-section. The filaments are arranged in a three-dimensional (3D) structure configured to disturb laminar flow through the protective barrier and increase contact with the antimicrobial additive.

The present disclosure discloses an embossed patterned elastic laminate. The elastic laminate has an embossed pattern of at least three surface areas. The current disclosure also includes a process for making an embossed patterned elastic laminate. The embossed patterned elastic laminate provides a permanent change to visual aesthetic without adversely impacting the elastic film.

A fiber sheet of the present disclosure includes: a first fiber layer including a plurality of first fibers, the plurality of first fibers comprising a thermoplastic polymer and arranged side by side in a first direction; a second fiber layer including a plurality of second fibers, the plurality of second fibers comprising a thermoplastic polymer and arranged side by side in a second direction intersecting the first direction, and disposed to face the first fiber layer; and a nanofiber layer including nanofibers, the nanofibers comprising any one of a thermoplastic polymer, a thermosetting polymer, a biodegradable polymer, and a biological polymer, the nanofiber layer disposed to be in contact with the first fiber layer and the second fiber layer, in which the nanofiber layer is heat-welded to the first fiber layer and the second fiber layer.

Embodiments disclosed herein include a stitched filtering fabric including a barrier layer configured to inhibit air flow through the filtering fabric, a yarn stitched through and forming a plurality of stitch holes in the barrier layer, and a first yarn layer comprising interlocking loops of the yarn. The barrier layer is configured to direct air flow through the yarn within the stitched holes.

A method of making a wet friction material includes joining filler particles and fibers together and forming a base; coating an outer surface of the base with a quaternary ammonium salt containing solution; and drying the quaternary ammonium salt containing solution to form a quaternary ammonium salt containing coating on the outer surface of the base.
