The present disclosure relates to a manufacturing method of a vehicle seatback cover, comprising a lightweight composite manufacturing step of manufacturing a lightweight composite using a reinforcing fiber and a thermoplastic resin fiber, a lightweight composite forming step of forming the lightweight composite into a vehicle seatback cover shape and preparing a vehicle seatback cover material, and a carpet bonding step of bonding the vehicle seatback cover material and a carpet material.

Lightweight, structurally reinforced thermoplastic objects comprising at least one reinforcement zone are manufactured by providing a heatable rigid forming chamber with a chamber volume. At a temperature below the thermoplastic softening temperature, the chamber is loaded with a plurality of thermoplastic lofting bodies and a plurality of thermoplastic reinforcement bodies wherein the lofting bodies are heat-loftable bodies comprising a thermoplastic matrix containing an elastically compressed assembly of reinforcement fibers embedded therein, lofty non-woven bodies comprising an elastically compressible assembly of reinforcement fibers and thermoplastic fibers. Upon closing the chamber, lofting bodies of lofty non-wovens are elastically compressed, producing an internal pressure. After heating the chamber above softening temperature, reinforcement bodies and lofting bodies are ow thermoplastically formable, and lofting bodies configured as heat-loftable bodies produce a second internal pressure. After a predetermined processing time, the chamber is cooled yielding a structurally reinforced object.

A thermoplastic core-sheath fiber comprises: a polymer fiber core having a coextensive sheath layer disposed thereon, and an electrostatic charge enhancing additive. The sheath layer may comprise poly(4-methyl-1-pentene) and the fiber core and the sheath layer have different compositions. At least one of the fiber core or the sheath layer comprises an electret charge. A nonwoven fibrous web comprising the core-sheath fibers and a respirator including the nonwoven fibrous web are also disclosed.

A laminated assembly extends in a longitudinal direction and a lateral direction orthogonal to the longitudinal direction, the assembly including a non-woven sheet and an elastic film that are laminated together, the non-woven sheet including at least one activated zone extending over the length of the non-woven sheet measured in the longitudinal direction and over a width that is strictly less than the width of the non-woven sheet measured in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction being different from the degree of activation of the elastic film in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction lying in the range 20% to 200%.

Woven UHMWPE fabric stretches in the bias direction to such an extent that it is unsuitable for many potential applications and is porous, allowing air and water transmission. A composite UHMWPE material includes a single ply of high tenacity woven UHMWPE fabric having warp fibers in a first direction and weft fibers in a second direction orthogonal to the first direction. The UHMWPE fabric has first face and a second face. A stretch resisting axially oriented fusion layer is fused to at least one of the first face or the second face of the UHMWPE fabric with an axis aligned parallel to at least one of the UHMWPE fabric warp and weft axes, such that the stretch resisting fusion layer increases fabric tensile strength and inhibits bias stretch of the UHMWPE fabric, and renders the UHMWPE woven fabric air and water impermeable.

A transfer system for a composite material including: a nonwoven as carrier material and a textile layer of reinforcing fibers, wherein the reinforcing fibers consist of mono- or multifilaments or tapes and the carrier material is adhesively bonded to the layer of reinforcing fibers.

A polyolefin microporous film having a laminated structure provided with at least one layer A containing a polyolefin and at least one layer B containing a polyolefin. 0 mass % to less than 3 mass % of polypropylene is contained in layer A and 1 mass % to less than 30 mass % of polypropylene is contained in layer B. When the proportion of polypropylene contained in layer A is represented by PPA (mass %) and the proportion of polypropylene contained in layer B is represented by PPB (mass %), PPB>PPA. In the polyolefin microporous film, the heat shrinkage ratio in TD at 120° C. measured upon applying, in MD, a constant load determined on the basis of the relationship: load (gf)=0.01×piercing strength (gf) of polyolefin microporous film×length (mm) in TD of polyolefin microporous film, is 10 to 40% inclusive.
