Abstract: 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 including thermally activated bonds between a first polyolefin material produced with a catalyst including 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.
