Abstract
The present invention relates to the manufacturing equipment for web materials comprising fibers and particulate material, to a process of operating such an equipment and to particular materials resulting therefrom. Coaxially meltblown fibres are combined with a stream of particulate or short fiber material and the resulting commingled mixture is deposited onto a collector. The meltblown fibers are formed by nozzles which are divided into two or more sub-arrays configured to produce two or more different types of fiber, having e.g. different diameters and/or polymer composition.
