A base web is comprising a base web consisting of synthetic fibers, air-laid cellulose fibers or synthetic fibers or cellulose fibers mixed with synthetic fibers air-laid in form of fluff on the base web, and a structure obtained by hydroentangling the fluff on the base web. The weight of the web is between 80 and 2000 g/m<2>. The heavy-duty webs of the invention can advantageously be used for producing e.g. corrugated board and heat- and/or sound-insulating materials. |
