Abstract:
The invention described relates to a polyolefin blend composition suitable for spunbond fiber or filament compositions, and to fabric compositions and composite constructions therefrom, said blend comprising a) from 60-98 wt % of at least one random propylene copolymer having a comonomer content of from 8 to 25 wt % and a crystalline melting point (Tm) as determined by differential scanning calorimetry (DSC) of from about 40° C. to about 110° C.; and b) from 2-40 wt % of at least one substantially isotactic polypropylene homopolymer or copolymer comprising one or more C2 and/or C4-C8 comonomer, having a crystalline melting point (Tm) as determined by DSC greater than or equal to 120° C. The blends of the present invention typically have a melt flow rate (MFR) of from 100 g/10 min to about 500 g/10 min.
