摘要

The present invention provides a method for the production of bounded non-wovens carriers. The method includes providing a glass staple fiber containing non-woven which is pre-consolidated with a binder. The glass staple fiber non-woven is placed adjacent to one or more non-wovens of synthetic fibers and hydro-dynamically needling at a water beam pressure in the range of 100 to 400 bar.
