Described is a ribbon yarn made of multifilament yarns based on polyamide and/or polyester, wherein not more than 5 filaments overlie one another within the ribbon yarn, wherein the ribbon yarn is fixed by the formation of a matrix comprising one or more fixing agents, wherein the one or more fixing agents are selected from a group consisting of copolyamides, copolyesters, silicones, and mixtures or blends thereof.

A trim component for attachment to a vehicle seat includes a first portion and a second portion. The first portion is disposed on a first side of the trim component and defines a first knit. The second portion is disposed on a second side of the trim component and defines a second knit distinct from the first knit. The first and second portions are integrally knitted. The trim component is configured to be installed on or more support members of the seat. The first side is configured to face the support member. The second portion is configured communicate with an occupant of the seat. In various aspects, the first portion includes a first yarn and the second portion includes a second yarn that is distinct from the first yarn with respect to one or more of density, thickness, and material. In various aspects, the first yarn is a heat-activated yarn.

A vehicle includes a first vehicle member, a second vehicle member, and a knit element connected to the first vehicle member and the second vehicle member.

An apparatus for production of a low-shrinkage aliphatic polyamide fibre, in which polyamide is extruded through a spinneret to form filaments, then cooled and combined to form at least one yarn. The at least one yarn is subjected to drawing between the spinneret and a pair of inlet rolls, then in a further multi-stage drawing step is subjected to 4-fold to 6-fold drawing by pairs of draw rolls. The pairs of draw rolls successively heat the yarn and at least the last pair of draw rolls has a temperature of 5 C. to 20 C. below the melting point of the yarn. The yarn is relaxed by from 6% to 10% in a subsequent at least three-stage relaxation zone and is kept in a temperature range of 5 C. to 15 C. below the melting point of the yarn, and is subsequently wound up on a reel device.

A motion sickness mitigation device includes a textile material having a first surface, a second surface disposed opposite the first surface, and a first raised portion extending from the first surface and configured for contacting a skin of a user. The textile material defines a first pocket and a second pocket therein between the first surface and the second surface, and the second pocket is spaced apart from the first pocket. The device further includes a controller disposed within the first pocket and configured for transmitting an electrical signal. The device also includes a first electrical excitation pad disposed within the second pocket, covered by the first raised portion, and disposed in electrical communication with the controller. The first electrical excitation pad is configured for receiving the electrical signal and electrically stimulating the skin of the user through the textile material to thereby mitigate motion sickness.

Yarns are formed of a copolyamide in an amount of at least 90 wt % with respect to the total weight of the yarn, wherein copolyamide includes (a) at least 95 wt % by weight with respect to the total weight of copolyamide, monomeric units derived from hexamethylene diamine and adipic acid 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. The summed amount of monomeric units derived from X, Y and Z is between 0.1 to 4.5 wt % by weight with respect to the total weight of the copolyamide. The yarns have a tensile strength of at least 80 cN/tex as measured according to ASTM D885-04.

The invention relates to a drive belt (1) having a main body into which one or more tension strands (3) composed of para-aramid in cord construction are embedded, wherein each tension strand (3) has twisted plies each formed from at least one twisted yarn, and wherein the turning direction of the respective ply (first twist) is the opposite of the turning direction of the cord (final twist). It is a feature of the invention that the tension strands (3) each have at least four plies, wherein the twist factor TM.sub.1 of the plies (first twist) is between 4.5 and 5.4, and the twist factor TM.sub.2 of the cord (final twist) is between 2.7 and 3.8, and the ratio of the twist factor of the plies to the twist factor of the cord (TM.sub.1/TM.sub.2) is between 1.3 and 1.5.
