The invention relates to a Yarn comprising a copolyamide in an amount of at least 90 wt % with respect to the total weight of the yarn, which copolyamide comprises a) at least 95 wt % with respect to the total weight of copolyamide, monomeric units derived from epsilon-caprolactam and b1) cyclic monomeric units derived from a diamine X, and cyclic monomeric units derived from a diacid Y, and/or b2) cyclic monomeric units derived from an amino acid Z, in which the summed amount of monomeric units derived from X,Y and Z is between 0.1 to 4.5 wt % with respect to the total weight of the copolyamide and wherein the yarn has a tensile strength of at least 80 cN/tex as measured according to ASTM D885-04. The invention also relates to a process for preparing the yarn.

A knit sleeve for providing thermal protection about an elongate member contained therein and method of construction thereof is provided. The sleeve includes a knit inner wall with opposite edges extending lengthwise between opposite ends and a circumferentially continuous tubular outer wall knit integrally with the inner wall. The outer wall bounds a central cavity that extends lengthwise along a central axis between open opposite ends of the outer wall. The opposite edges of the inner wall are substantially parallel to the central axis and are wrappable toward one another to form the inner wall as being tubular. The circumferentially continuous tubular outer wall is configured to be everted about the wrapped inner wall to circumferentially surround and protect the inner wall from abrasion and provide the sleeve with a dual layer wall.

The present invention provides a carbon fiber cord having both high bending fatigue resistance and high adhesiveness. The disclosed carbon fiber cord is a carbon fiber cord for reinforcing a rubber product. This carbon fiber cord includes a carbon fiber, a first coating layer formed on the carbon fiber, and a second coating layer formed over the first coating layer. The first coating layer contains a phenolic resin and does not contain a rubber component. The second coating layer contains a rubber component. The mass ratio of the first coating layer to the total mass of the carbon fiber and the first coating layer is in a range of 0.5% to 10%.

A hybrid cord comprises (i) a first yarn, without initial S or Z twist, of continuous polymeric filaments forming the core of the cord, the yarn being a non-bulked yarn, (ii) a second yarn, without initial S or Z twist, of continuous polymeric filaments, the second yarn being a bulked yarn that is wrapped around the first yarn, wherein (a) the second yarn is wrapped around the first yarn at an angle of from 5 to 40 degrees, (b) the second yarn has a length that is from 4 to 35 percent longer than that of the first yarn, and (c) the hybrid cord is unbalanced and has an S or Z twist.

A flexible multilayer battery pack insulator for an electric vehicle has a multilayer wall including a plurality of layers of interlaced mineral material including an inner layer having a first exposed, outwardly facing surface and an outer layer having a second exposed, outwardly facing surface. A first flame-resistant coating is bonded to at least one of the plurality of layers. A pressure-sensitive adhesive is bonded to the first exposed, outwardly facing surface of the inner layer. At least one filament fixes the plurality of layers to one another.

A twisted and coiled polymer fishing line (TCP.sub.FL) actuator, method, and computer program product for using the TCP.sub.FL actuator. A TCP.sub.FL actuator may be received, wherein the TCP.sub.FL actuator is fabricated from a plurality of TCP.sub.FL muscles. The TCP.sub.FL actuator may be used to adjust a vehicle component.

The invention relates to an arrangement comprising a visible seam, which is arranged in a sheet material part. The arrangement also includes a lighting apparatus, which is arranged beneath an underside of the sheet material part. The visible seam has an upper thread and a lower thread. The lower thread extends along the underside of the sheet material part in a direction. The upper thread has first thread portions along the upper side of the sheet material part and is guided, at stitch holes formed during the sewing process, through said stitch holes via second thread portions. By means of the lighting apparatus, emitted light passes into the second thread portions, into the stitch holes, and from there into the first thread portions. Some of the light propagates along the first thread portions, starting from an adjacent second thread portion, whereas another portion of the light exits from the first thread portion. In this way, the upper thread of the visible seam is illuminated.
