Problems solved by technology

However, PEF has a tendency to crystallize rapidly after the process of spinning to obtain yarn, and thus the material is sometimes brittle, unsuitable for winding and unsuitable for stretching

Embodiment Construction

[0024] Reinforcing cords may consist of twisted continuous multifilament yarns. However, it is also possible that the reinforcing cord comprises at least one further yarn made of filaments, wherein these yarns are twisted together at the ends. For example, there are possible cord constructions in which two (2-end configuration) or three (3-end configuration) yarns are end-twisted to give a reinforcing cord.

[0025] The one or more additional yarns may consist of filaments of different materials. If yarns made of different materials are present within a reinforcing cord, then this is a so-called hybrid cord.

[0026] The material of this additional yarn may preferably be a non-metallic material such as polyester, aliphatic and aromatic polyamide, aramid, polyetherketone, polyketone, polyethylene naphthalate, viscose, Natural fiber or fiberglass. The properties of the reinforcing cords can be adjusted by an appropriate choice of material.

[0027] In a preferred further dev...

Abstract

The invention relates to a reinforcement cord for elastomer products, in particular for vehicle tires, containing at least one yarn made of filaments. The invention additionally relates to an elastomer product which contains at least one reinforcement cord. In order to protect the environment and preserve resources while maintaining a good processing behavior, at least one yarn of the reinforcement cord contains filaments made of polybutylene furandicarboxylate (PBF), wherein the PBF is completely or at least partly made of biomass and / or renewable raw materials.

Description

technical field [0001] The invention relates to a reinforcing cord for elastomeric products, in particular pneumatic tires, comprising at least one yarn made of filaments. [0002] The invention further relates to an elastomeric product comprising at least one reinforcing cord. Background technique [0003] Reinforcement cords are offered for the reinforcement of many elastomeric products such as hoses, conveyor belts, transmission belts and pneumatic tires. Reinforcement cords consist of one or more yarns twisted together and are known to those skilled in the art in a very wide variety of embodiments with regard to construction and materials. Where two or more yarns are present, the material may be the same, or, as in the case of hybrid cords, at least two different yarns may be present. These yarns are usually composed of many individual filaments (fibers). For example, reinforcing cords are used in elastomeric products in the form of woven fabrics, laid scrims or knitt...
