A fluoropolymer composite film wire or cable wrap comprises an outer layer of expanded polytetrafluoroethylene (ePTFE) and an inner layer of melt processable fluoropolymer film. The inner and outer layers are laminated with each other in tape form, such as by the application of heat and/or pressure thereto. The fluoropolymer composite tape is wrapped about one or more wires or cables, and is heated or sintered after wrapping to bond the tape to the wire or cable, and bond the tape to itself at the seams.

A microwave-induced heating of CNT filled (or coated) polymer composites for enhancing inter-bead diffusive bonding of fused filament fabricated parts. The technique incorporates microwave absorbing nanomaterials (carbon nanotubes (CNTs)) onto the surface or throughout the volume of 3D printer polymer filament to increase the inter-bead bond strength following a post microwave irradiation treatment and/or in-situ focused microwave beam during printing. The overall strength of the final 3D printed part will be dramatically increased and the isotropic mechanical properties of fused filament part will approach or exceed conventionally manufactured counterparts.

Cut-resistant and abrasion-resistant yarns including blends of technical fibers and mineral, inorganic, or ceramic fibers of substantially the same length as the technical fibers, and methods for manufacturing yarns, are disclosed.

Provided is a conjugate fiber for air-laid nonwoven fabric manufacture having a planar zig-zag crimp shape before a thermal treatment, such that a uniform web is obtained by air laying with high processability and productivity, and the conjugate fiber develops a spiral crimp when the web is subjected to a thermal treatment to thereby enable the web to shrink significantly, as a result of which a nonwoven fabric can be obtained in which fibers are amassed to a high density. The conjugate fiber for air-laid nonwoven fabric manufacture is a heat-fusible conjugate fiber in which a first component comprising an olefinic thermoplastic resin is conjugated with a second component comprising an olefinic thermoplastic resin having a melting point higher than that of the first component. The conjugate form is such that the centers of gravity of the conjugate components are mutually different in the fiber cross section, the fiber has a single-yarn fineness of 1 to 10 dtex, a fiber length of 3 to 20 mm, and a planar zig-zag crimp whose crimp shape index (actual length of short fiber/distance between both ends of short fiber) ranges from 1.05 to 1.60, and the web shrinkage upon thermal treatment at 145 C. of a web obtained by an air-laid method is not lower than 40%.
