Embodiment Construction

[0010] The term "fiber" includes a linear configuration formed from one or more monofilaments / filaments, wherein the monofilaments may be filaments or staple fibers. A linear configuration formed by a plurality of filaments is also called a multifilament yarn, and a linear configuration formed by one filament is called a monofilament yarn.

[0011] A "textile reinforcement consisting essentially of fibers from the group of aliphatic polyamides" is to be understood as meaning a textile reinforcement which consists at least predominantly of fibers from the group of aliphatic polyamides. The textile reinforcement preferably consists of at least 60% by weight of fibers selected from the group of aliphatic polyamides. Furthermore, such a textile reinforcement preferably consists of at least 70% by weight, at least 80% by weight and particularly preferably at least 90% by weight of fibers selected from the group of aliphatic polyamides. Of course, the textile reinforcement can also...

Abstract

The invention relates to a hose, comprising an elastomeric material and a textile reinforcement, the textile reinforcement being made substantially of fibers selected from the group of aliphatic polyamides, characterized in that the heat shrinkage of the fibers is smaller than 2.5%.

Description

technical field [0001] The invention relates to a hose made of an elastomeric material with a textile reinforcement, in particular to a textile reinforcement based on polyamide fibres. [0002] This hose is especially suitable for use in cooling systems. In modern water-cooled or liquid-cooled vehicle engines, the cooling system has reinforced hoses made of flexible material through which the liquid circulates to and from the cooler. Background technique [0003] DE 2 063 641 discloses a reinforced hose which is preferably reinforced by a single layer consisting of a treated polyester or nylon fabric. [0004] Currently, aramid fibers are also used for this purpose. However, hose reinforcements made of polyester fibers or aramid fibers have only a low resistance to hydrolysis at elevated cooling medium operating temperatures. [0005] However, a good hydrolytic stability of the textile reinforcement is a prerequisite for the production of thinner-walled hoses, since in su...
