摘要： An orientated polyolefin composition comprising an olefin (co)polymer having a weight average molecular weight (Mw) from 30,000 to 1,000,000 and a high molecular weight tail extending to molelcular weights above 1,000,000, and has a microstructure which is substantially parallel chain extended cores of the component polymer(s) and associated lamellar overgrowths extending in planes normal to the cores in which the lamellar overgrowths on adjacent cores intermesh and are capable of sustaining a haul off tension of at least 10 MPa without breaking during its extrusion, is produced by extruding an olefin copolymer through a die under a pressure of about 5-10 MPa, at a temperature above the self-blocking temperature thereof and by hauling off the extrudate at a tension of at least 10 MPa without breaking. The extrudates so produced have a high modulus.

摘要： Low viscosity ethylene acrylic copolymers and blends thereof with other fiber-forming polymers for spunbond and melt blown nonwoven applications. Ethylene/alkyl (meth) acrylate, especially ethylene/methyl acrylate copolymers are found to be suitable for fiber-forming operations, especially melt blowing when the melt index is at least about 10. Blends of the copolymer with other fiber-forming polymers are especially suitable for fiber-forming operations. The nonwoven products of the copolymers and blends of the invention show a good degree of elongation making them especially suitable for certain fabric applications and new uses. The nonwoven fabrics are comprised of fibers of the copolymers and blends, having a diameter of about 1-40 microns. Larger fibers may also be formed by various techniques.

摘要： A remarkable degree of softness and flexibility is imparted to products such as artificial fur, soft woven or knitted fabrics and the like by using relatively small diameter fibers having a low elastic modulus. The fiber diameter and elastic modulus are selected to obtain a stiffness parameter of less than 8.5.times.10.sup.-9 but preferably greater than 1.0.times.10.sup.-11 lb-in.sup.2.

摘要： Fibers can include a polypropylene composition, which can include a metallocene random copolymer of propylene and a comonomer that is an alpha-olefin different from propylene. The metallocene random copolymer can have a comonomer content of from 1.2 wt % to 1.8 wt %, a molecular weight distribution of at least 1.0 and of at most 4.0 obtained without thermal or chemical degradation, and a melting temperature Tmelt of at most 140° C. A nonwoven can include the fibers, and a laminate can include the nonwoven. The fibers can be produced by polymerizing the propylene and comonomer in presence of a metallocene-based polymerization catalyst to obtain the metallocene random copolymer. The polypropylene composition can be melt-extruded to obtain a molten polypropylene stream, which can be extruded from capillaries of a spinneret to obtain filaments. A diameter of the filaments can be rapidly reduced to obtain a final diameter.

摘要： A method, system, and resulting linear fibrous formation are provided wherein a supporting linear formation defines a core that is transported through a spinning chamber. A coating of polymeric nanofibers enveloping the supporting linear formation in the spinning chamber. The coating of polymeric nanofibers comprises a flat stripe wound around the core into a helical form, the flat stripe created from a hollow electrically neutral nanofibrous plume generated in a spinning space above a spinning electrode during spinning by AC electric voltage in the spinning chamber.
