A process comprising forming fibers having at least a first region and a second region wherein the first region comprises an ethylene/alpha olefin interpolymer composition characterized by: density in the range of 0.930 to 0.965 g/cm.sup.3; melt index (I2) in the range of from 10 to 60 g/10 minutes; molecular weight distribution in the range of from 1.5 to 2.6; tan delta at 1 radian/second of at least 45; a low temperature peak and a high temperature peak on an elution profile via improved comonomer composition distribution (ICCD) procedure; and full width at half maximum of the high temperature peak is less than 6.0? C. and stretching the fibers to an elongation of at least 20% thereby increasing curl of the fiber. The process may further include forming a non-woven from the fibers and the stretching of the fibers may occur before or after forming of the non-woven.

The invention relates to bone repair and more specifically to a berberine/mineralized collagen-based composite membrane, a preparation method, and an application thereof. The composite membrane includes a berberine nanofiber membrane and a mineralized collagen membrane disposed on a unilateral surface of the berberine nanofiber membrane. The mineralized collagen with biomimetic mineralization capacity is combined with a Chinese materia medica monomer, berberine, the resulting bilayer composite membrane has a better effect on promoting osteogenesis In addition, a novel dosage form of berberine is constructed. An electrospinning method prepares a berberine nanofiber membrane. The berberine nanofibers are received by the mineralized collagen membrane, or after the berberine nanofiber membrane is obtained, a mineralized collagen membrane is prepared by applying on the surface of the berberine nanofiber membrane.
