Abstract (en)

[origin: US2015017866A1] A bi-component fiber (1), in particular for the production of spunbond fabrics (4), with a first component (2) and a second component (3), whereby the first component (2) has a first polymer as an integral part and the second component has a second polymer as an integral part. It is provided that the difference between the melt-flow indices of the first component (2) and the second component (3) is less than or equal to 25 g/10 minutes and that the melt-flow indices of the first component (2) and the second component (3) in each case are less than or equal to 50 g/10 minutes.
