SPUNBOND NONWOVEN FABRICS |
摘要 |
The instant invention provides nonwoven fabrics and staple or binder fibres prepared from an ethylene-based polymer having a Comonomer Distribution Constant in the range of from greater than from 100 to 400, a vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range from 1 to less than 2; a density in the range of 0.930 to 0. 970 g/cm3, a melt index (12) in the range of from 15 to 30 or from 10 to 50 g/10 minutes, a molecular weight distribution (Mw/Mn) in the range of from 2 to 3.5, and a molecular weight distribution (Mz/Mw) in the range of from less than 2. |

1. A non-woven fabric comprising monocomponent fibers prepared from an ethylene-based polymer composition comprising:
less than or equal to 100 percent by weight of the units derived from ethylene; and less than 30 percent by weight of units derived from one or more α-olefin comonomers; wherein said ethylene-based polymer composition is characterized by having a Comonomer Distribution Constant in the range of from greater than from 100 to 400, a vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range from 1 to less than 2; a density in the range of 0.930 to 0. 970 g/cm3, a melt index (I2) in the range of from 15 to 30 g/10 minutes, a molecular weight distribution (Mw/Mn) in the range of from 2 to 3.5, and a molecular weight distribution (Mz/Mw) in the range of from less than 2. |
