摘要： The present invention relates to a method for assembling particles having a long axis, a short axis and an average aspect ratio of 10-10,000. The method includes agitating a combination of a first solution, a second solution and the particles in any order to form a mixture wherein one of the first solution and the second solution is in the form of droplets dispersed in the other of the first solution and the second solution and the long axis of the particles is longer than a diameter of the droplets in the mixture, and continuing the agitation until the particles assemble into aggregates of particles with at least 30% of the particles aligned in parallel along the long axis. Aggregate or aggregate composites form by the method are also described.

摘要： The invention relates to a method for producing synthetic fibres from a melt blend that is based on fibre-forming matrix polymers. According to said method, at least one second amorphous additive polymer is added to the fibre-forming matrix polymers, said additive polymer being incompatible with the fibre-forming matrix polymer, in a quantity of 0.05 to 5 wt.- %, relative to the combined total weight of fibre-forming matrix polymer and the additive polymer with which it is incompatible. The method is characterized in that an additive polymer, which can be obtained by multiple initiation, is added. The invention also relates to synthetic fibres obtained by said method and to the further processing of the same.

摘要： The present disclosure is directed to a method of forming a treated fiber. A molten polymer is delivered to a fiber spinning assembly adapted to form and distribute polymer streams. At least one treatment is applied in a liquid state to at least one region on the surface of at least one molten polymer stream within the fiber spinning assembly. A substantial portion of the treatment remains on the surface of the resulting fiber within the treated region. One or more regions on the surface of the molten polymer may be treated with one or multiple treatments. The degree of coverage may vary from little coverage to complete coverage of the fiber surface. The treated regions may be in contact with one another or may be separate and distinct. A nonwoven web may be produced with selectively treated fiber regions by designing one or more fiber spinning assemblies to treat selected fibers or to apply multiple treatments. The regions of the nonwoven web may vary in treatment type, amount, or degree of coverage.

摘要： This invention relates to eco-friendly solutions and gels for making high strength ultra-high molecular weight polyolefin (UHMWPO) fibers, films, filters, membranes by solution and gel spinning techniques. This invention also makes soft, strong, oriented, and elastic fibers from styrenic block copolymers. The polymers are first dissolved or dispersed in a cyclic terpene. In some embodiments, the fibers are extruded or drawn from the solution or gel, and cooled to form a gel filament. In some embodiments, the fibers and films are soft and elastic by making the spinnable solution or gel from polyolefin and styrenic block copolymers or other elastomeric polymers in cyclic terpene. In some embodiments the fibers and films produced can be oriented by stretching or drawing in the gel state before and/or during and/or after removal of cyclic terpene.
