The fiber product may be comprised of substantially unbonded fibers.

Accordingly, the nonwoven has unbonded fiber portions (30) and bonded fiber portions (32), with a bonded portion/unbonded portion ratio greater along the second direction (14) than along the first direction (12).

The filter may comprise unbound fibers, or the fibers may be bound with a binder to form a composite of fibers.

The method is characterized in that the binding treatment by means of water jets is carried out on a lap, comprised of a homogenous mixture of unbound fibres of wood pulps and synthetic fibres, formed by aeraulic process.

The fiber product may be comprised of substantially unbonded fibers.

Accordingly, the nonwoven has unbonded fiber portions (30) and bonded fiber portions (32), with a bonded portion/unbonded portion ratio greater along the second direction (14) than along the first direction (12).

The improved densification properties are observed without the presence of particles bound to the fibers or in the presence of particles that are not bound to the fibers.

A nonwoven wipe has multiplicity of fibers, bonded portions, and unbonded portions.

These coarse fibers (8) comprise in particular staple fibers or spun-bonded fibers.

The nonwoven web includes two layers of spunbond fibers and one layer of meltblown fibers.

The nonwoven web includes two layers of spunbond fibers and one layer of meltblown fibers.

The nonwoven web includes three layers of spunbond fibers and two layers of meltblown fibers.

The filter may comprise unbound fibers, or the fibers may be bound with a binder to form a composite of fibers.
