Abstract (en)
The present invention relates to a propylene polymer fibre with improved bonding properties, a process for the production of such fibres and a process for the production of a non-woven by bonding of webs formed by such fibres as well as their use. Therefore, a propylene polymer fibre with improved bonding properties is provided, which is characterized in that it comprises a lactone of the furan-2-one type in an amount of at most 200 ppm. Furthermore, a process for the production of propylene polymer fibres with improved thermo bonding properties is disclosed, characterized in that a lactone of the furan-2-one type in an amount of 200 ppm or less is added to a propylene polymer before spinning of the fibres.
