The polylactic acid based polymer is selected from the group consisting of poly-D-lactic acid, poly-L-lactic acid, copolymers of D-lactic acid and L-lactic acid, copolymers of D-lactic acid and a hydroxycarboxylic acid, copolymers of L-lactic acid and a hydroxycarboxylic acid, and copolymers of D-lactic acid, L-lactic acid and a hydroxycarboxylic acid, which have melting points of not lower than 100° C., and blends of any of these polymers which have melting points of not lower than 100° C. The filaments of the polylactic acid based polymer have a birefringence of 10×10−3 to 25×10−3, a degree of crystallinity of 12 to 30 wt %, and a crystal size of not greater than 80 Å as measured axially of the filaments. The nonwoven fabric has a boiling water shrinkage percentage of not higher than 15%.

    摘要： An apparatus for providing a uniform web of filaments comprises tube filament transport means exiting through a confined zone of reduced turbulence, which preferably comprises a delivery slot. The delivery slot is configured with sidewalls substantially parallel to one another and to the transport tubes, so that filaments undergo minimal machine direction deflection in the slot. Charging means within the slot charge the filaments for further cross direction separation. A method of providing a uniform web of filaments comprises transporting filaments through transport tubes, through a tapered transition member, and into a delivery slot. The delivery slot is defined by sidewalls that are substantially parallel to one another and to the transport tubes, so that minimal machine direction deflection of the filaments occurs. The filaments are also charged by electrostatic charging means while they are in the slot for further separation. The method and apparatus of the invention provide for a uniform filament web with high machine direction orientation.

    摘要： A nonwoven fabric from spun fibers wherein the density of the spun fibers in the fabric varies between strips of relatively high density and strips of relatively low density. The strips extend along the length of the fabric in the machine direction in an alternating pattern, with the high density strips separated from each other by low density strips. The alternating high density and low density strips provide the fabric with a higher percent elongation in the cross direction than in the machine direction. The alternating pattern is achieved through use of a pattern screen defining a plurality of elongated air permeable regions separated by elongated substantially or relatively air impermeable regions, the elongated regions extending in the machine direction in an alternating pattern, with the air permeable regions separated from each other by the substantially or relatively air impermeable regions.
