Embodiment 1
[0236] Inventive Example 1 was prepared by depositing two airlaid layers on a previously prepared ATB-1 fabric. The two airlaid layers included a homogeneous fiber mixture of pulp-1 fibers and PE / PET-1 fibers. After depositing the two airlaid layers, a coating of latex formulation was applied to the surface of the outermost airlaid layer. The composite sheet is then sequentially passed through a series of ovens to bond the fibers to each other and to dry and cure the latex formulation. The dry add-on weight of the latex layer was 2% by weight, based on the total weight of Inventive Example 1. The basis weight of the resulting composite sheet is 70g / m 2 .
[0237] The composite material sheet of Inventive Example 1 has the structure shown in Table 1 below.

Embodiment 2
[0241] Inventive Example 2 was prepared by depositing two airlaid layers onto a previously prepared ATB-2 fabric. The two airlaid layers included a homogeneous fiber mixture of pulp-1 fibers and PE / PET-1 fibers. After depositing the two airlaid layers, a coating of latex formulation was applied to the surface of the outermost airlaid layer. The composite sheet is then sequentially passed through a series of ovens to bond the fibers to each other and to dry and cure the latex formulation. The dry add-on weight of the latex layer was 2% by weight, based on the total weight of Inventive Example 2. The obtained composite sheet has a basis weight of 75 g / m 2 .
[0242] The composite material sheet of Inventive Example 1 has the structure shown in Table 2 below.

Embodiment 3
[0246] Inventive Example 3 was prepared by depositing two airlaid layers onto a previously prepared ATB-2 fabric. The two airlaid layers included a homogeneous fiber mixture of pulp-1 fibers and PE / PET-1 fibers. After depositing the two airlaid layers, a coating of latex formulation was applied to the surface of the outermost airlaid layer. The composite sheet is then sequentially passed through a series of ovens to bond the fibers to each other and to dry and cure the latex formulation. The dry add-on weight of the latex layer was 2% by weight, based on the total weight of Inventive Example 3. The obtained composite sheet has a basis weight of 85 g / m 2 .
[0247]The composite material sheet of Invention Example 3 has the structure shown in Table 3 below.
