3D SHAPED PACKAGING PRODUCT FROM AN AIR-LAID BLANK
A 3D shaped packaging product (20) for cushioning and/or thermal insulation of packaged goods is formed by hot pressing at an average pressure equal to or below 200 kPa of an air-laid blank (10) comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 4 up to 30% by weight of the air-laid blank (10). The 3D shaped packaging product (20) has a density that is less than four times a density of the air-laid blank (10) and the density of the 3D shaped packaging product (20) is selected within an interval of from 15 to 240 kg/m.sup.3. The 3D shaped packaging product (20) maintains at least a significant portion of the porosity of the air-laid blank (10) even after hot pressing and therefore provides excellent shock absorbing and damping properties and thermal insulation.

FOLDED 3D SHAPED PACKAGING PRODUCT FROM AN AIR-LAID BLANK
A folded 3D shaped packaging product (30) is folded at at least one crease (22A, 22B, 22C, 22D, 22E) constituting a folding line in a 3D shaped product (20) formed by hot pressing of an air-laid blank (10) comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 4 up to 30% by weight of the air-laid blank (10). The folded 3D shaped packaging product (30) is useful for cushioning and/or thermal insulation of packaged goods and can protect multiple sides of the packaged goods.
Needle punched carpet
A needle punched carpet for use in a car is disclosed. The needle punched carpet comprises at least a needle punched facing layer defining a top layer and made of staple fibers. The staple fibers comprise hollow fibers having a hollow fiber content that is at least more than 45 weight % of the total staple fibers.

Composite and methods of making same
Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.
