Abstract
Braided Hose and method for manufacturing a braided hose comprising an inner tube defining a longitudinal axis. The inner tube is made of an elastic material, such as a synthetic or natural rubber, or of a thermoplastic material. A first braided reinforcement layer envelops the inner tube. An outer protective layer covers the braided layer. A leno layer is placed between the inner tube and the first braided reinforcement layer. The inner tube comprises two or more layers, one of which is a vulcanized rubber layer, and another layer is made of a textile fabric.

A braided hose comprising:
- an inner tube defining a longitudinal axis and made of an elastic material, including a synthetic or natural rubber, or of a thermoplastic material;
- a first braided reinforcement layer enveloping the inner tube;
- an outer protective layer;
- wherein a leno layer is placed between the inner tube and the first braided reinforcement layer (4);
- and
- the inner tube includes two or more layers, at least one of which is a vulcanized rubber layer, and at least another layer is made of a textile fabric.
A method of manufacturing a braided hose comprising the steps of:
- a) providing a mandrel;
- b) applying a synthetic or natural rubber, or a thermoplastic material on the mandrel to form an inner tube around the mandrel, wherein the inner tube comprises two or more layers, one of which is a vulcanized rubber layer, and another layer is made of a textile fabric;
- c) enveloping the inner tube with a leno layer being a net, a web, fabric, or a mesh out of metal, plastic, or reinforced plastic strands or of textile filaments or mixture thereof;
- d) applying a braided reinforcement layer on the leno layer;
