Carbon nanotube threads are coated with a coating solution such as dimethylformamide (DMF), ethylene glycol (EG), polyethylene glycol (PEG), PEG200 (PEG with a average molecular weight of approximately 200 grams per mole (g/mol)), PEG400 (PEG with a average molecular weight of approximately 400 g/mol), dimethyl sulfide (DMS 100 cP), HP1632, poly(methylhydrosiloxane), polyalkylene glycol, (3-aminopropyl)trimethoxysilane, hydride functional siloxane 0 resin, platinum (0) -1,3-divinyl-1,1,3,3-tetramethyl-disiloxane, moisture in air, acetic acid, water, poly(dimethylsiloxane) hydroxy terminated, (3-glycidyloxypropyl)-trimethoxysilane or a combination thereof. The coated carbon nanotubes may be used to stitch in a Z-direction into a composite such as a polymer prepreg to strengthen the composite. The stitching may occur using a sewing machine.

A configuration and manufacturing method for a trailing edge of an aircraft airfoil, such as a control surface or a lifting surface is described. The trailing edge is formed and configured by upper and lower composite covers, which are stitched to each other with a metallic wire, such as the metallic wire is electrically in contact with upper and lower metallic meshes to provide electrical continuity between meshes. According to a method, upper and lower covers configuring the trailing edge, are stitched with the metallic wire before curing the covers, so that the metallic wire gets embedded within the composite material. A trailing edge for an aircraft airfoil, which is easy to manufacture and that at the same time fulfills aerodynamic, mechanical and electrical conductivity requirements is described.

A hand sewing and knitting needle comprises an elongate body having a first end section extending from a first end to a middle section. The elongate body having a second end section beginning at the middle section and extending to the second end of the second end section. The middle section extending from a second end of the first end section to the first end of the second end section.

The wire harness includes a sheathing member that is formed in a sheet shape, at least one electric wire that is arranged on a first principal surface side of the sheathing member, and a sewing thread that sews the electric wire to the sheathing member. A partial region of the sheathing member that is arranged along an extension direction of the electric wire is in a flat state, while another at least partial region of the sheathing member that is arranged along the extension direction of the electric wire is curved in a direction intersecting with the extension direction of the electric wire.

The invention relates to a gripper for a tufting machine, which has a gripper body and an insert. In the longitudinal direction, the gripper has a holding section and a guiding section. At the end further away from the holding section, in the longitudinal direction, the guiding section terminates in a hook which has an inner side in which a joint gap is arranged between the gripper body and the insert. According to the invention, the gripper is characterised in that a stop means, against which the insert abuts in the longitudinal direction towards the holding section, is arranged on the gripper body in the gripper's guiding section in order to limit the size of the joint gap in the inner side of the hook.

The present invention provides a technology that enables both a region that is arranged flat and a region that is arranged flexed on a wire harness to be easily accommodated using a single sheathing member. The wire harness includes a sheathing member that is formed in a sheet shape, at least one electric wire that is arranged on a first principal surface side of the sheathing member, and a sewing thread that sews the electric wire to the sheathing member. A partial region of the sheathing member that is arranged along an extension direction of the electric wire is in a flat state, while another at least partial region of the sheathing member that is arranged along the extension direction of the electric wire is curved in a direction intersecting with the extension direction of the electric wire.
