NON-WOVEN STRUCTURE WITH FIBRES CATALYZED BY A METALLOCENE CATALYST

The present invention describes a bonded and entangled non-woven structure made of at least 50% staple fibers by weight of the bonded and entangled non-woven structure, and at least a partial bonding of the fibers of the non-woven structure, the at least partial bonding comprising thermally activated bonds between a first polyolefin material produced with a catalyst comprising at least one metallocene catalyst and having a melting point in the range 130-170°C and a second material having a melting point which is at least 10°C higher than the melting point of the first material, the weight of the first material in the non-woven structure being at least 3% of the weight of the nonwoven structure, wherein the nature of the product is one of: a geotextile, a filtration product, thermal insulation, an acoustic absorption product, an acoustic dampening product, and a lining product.
