Abstract (en)
[origin: WO2016192097A1] A polymer composition for forming spunbond fabrics offers a unique combination of simplicity and processability, while allowing fabrics formed therefrom to exhibit suitable elasticity and/or tensile strength. The polymer composition includes an propylene-based elastomer component exhibiting a particular combination of MFR and comonomer content, so as to allow for improved processability with minimal, if any, need for blending partners in the polymer composition, while still permitting fabrics formed therefrom to exhibit improved elasticity and/or tensile strength.
