Abstract

An air-laid blank () comprises natural fibers at a concentration of at least 70% by weight of the air-laid blank () and a thermoplastic polymer binder at a concentration selected within an interval of from 2.5 up to 30% by weight of the air-laid blank (). The air-laid blank () has an average density and a portion () of the air-laid blank () has a density different from the average density. The air-laid blank () is produced by modifying the air-permeability of a portion () of an air-permeable collector () to form a portion () of the air-laid blank () having a density from the average density. The air-laid blank () has two parallel planar major surfaces ().
