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.

SPUNLACE COMPOSITE WEB COMPRISING STAPLE FIBERS, SHORT ABSORBENT FIBERS AND BINDER
The present invention relates to forming of fibrous webs and the resulting fibrous webs. The webs comprise at least one layer of staple fibers, as deposited in a carding process, and at least one further layer with hydrophilic short fibers, as may be cellulose fibers, and binder as being mixed with the hydrophilic short fibers. Fibers of the layers are mechanically entangled, e.g. by needlepunching or by hydroentangling / spunlacing. Such webs are particularly useful as wipes, especially absorbent wipes useful for personal cleansing as well as for treatment of surfaces.

The present invention relates to forming of bonded fibrous webs and the resulting fibrous webs which are e.g. useful as wipes. Liquid jets of a curable, liquid binder system are applied to the fibers whilst these are suspended in air, and hot air, as expelled concurrently with the binder system jets, induces drying and curing of the binder and its deposition on the fibers' surfaces. Upon lay down of the fibers forming a web, further curing may be induced.
