  • the braided hose is less subject to this problem with respect to the knitted hose, for certain applications it is desirable to minimize as much as possible or even completely overcome the swelling problem, as well as to improve the burst pressure.
  • hoses are known having one or more reinforcing layers fully consisting of high tenacity fibers, such as Kevlar ®, carbon fibers and the like. From EP-A- 0074747 is known an example of these hoses.
  • Another solution to the problem of the swelling known in the art of hose manufacturing is to increase the thickness of the outer PVC layer, in such a manner that it cooperate with the reinforcing layer to contrast the internal pressure.
  • Main object of the present invention is, therefore, to provide a braided garden hose, as well as a manufacturing process thereof, that minimizes or even completely eliminates the problem of swelling under pressure in an economical and simple manner.
