Abstract: This process comprises the steps of mixing fibres, such as polyester or other fibres, with silicone treated fibres of various nature and origin to produce, after carding, a web of mixed fibres which is then treated, on one face, with a mixture of sticky plastic bonding agents and subsequently pressed through a calender having two or more suitably heated cyl- inders which reduces the thickness of the web itself. At the output of the cylinders of the calender the product remains, for a short time, adhering with its sticky surface to the corresponding cylinder , thus being subjected to a slight expansion process which causes the formation of air pockets .
