A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A ballistic-resistant articles, and methods for their preparation, based on sheets of UHMWPE films with discontinuous film splits, which combine flexibility and good ballistic properties, making them suitable for both soft-ballistic and hard-ballistic applications.

The present invention provides methods for making and using antibacterial polymeric materials loaded with additives, as well as antibacterial materials comprising additives. Certain additives or combinations of additives show unexpected combinatorial or synergistic antibacterial activity. The invention also provides medical devices comprised of antibacterial polymeric materials, and methods of making and using such devices, which can have unexpected combinatorial or synergistic antibacterial activity.

A composition for three-dimension (3D) printing, a method for 3D printing, and a resulting article having porous structure are provided. Such a composition includes from 50% to 100% o by weight of a base polymer comprising polyolefin (such as ultra-high molecular weight polyethylene), from 0% to 50% by weight of a glue polymer (such as HDPE or PP), and optionally additive. A composition can be applied in a layer, and the base polymer and the glue polymer each has a predetermined size or size distribution. The composition is sintered in a selected area to form a layer of a solid article, which has a predetermined pore size or pore size distribution. The predetermined particle size or size distribution for each of the base polymer and the glue polymer is determined through computer simulation based on the predetermined pore size or pore size distribution in the layer of the solid article.

Embodiments relate to apparatus for manufacturing a carbon block filter and a method for manufacturing a carbon block filter. The apparatus for manufacturing a carbon block filter according to an embodiment may include a mold having an inner space, a heater coupled to the mold to heat the mold, a material injection unit injecting a material to the mold heated by the heater, a material pressing unit pressing the material, and a filter separation unit separating a thermally treated filter from the mold heated by the heater.

A polyolefin porous separator includes a first surface and a second surface corresponding to the first surface. The surfaces of the polyolefin porous separator contain dendritic crystals and micropores, the dendritic crystals intersect with the micropores on the first surface or/and the second surface, and the dendritic crystals penetrate through the second surface from the first surface. A preparation method of the polyolefin porous separator includes: (1) a mixed melting of polyethylene resin and a mineral oil; (2) an extrusion of the mineral oil/polyethylene resin molten mixture; (3) a stretching of a thick sheet in a machine direction (MD); (4) a stretching of the separator in a transverse direction (TD); (5) immersing the separator into a solvent to extract the mineral oil; (6) a secondary stretching of the separator in the TD; and (7) subjecting the separator having the longitudinal crystals to a heat-setting treatment and then rolling up.

The invention relates to a method and a device for manufacturing an articular prosthesis implant using a mould comprising a ceramic imprint (1) moved by a piston (2), the ceramic imprint (1) pressing the thermoplastic material introduced into the mould.

The present invention includes an injection moldable/extrudable composite that preserves at least 80% or enhances the primary physical properties of compression molded polymer, the composite comprising, e.g., an Ultra High Molecular Weight Polyethylene (UHMWPE) and graphene/graphite oxide or graphene oxide, with or without polypropylene.

A polyolefin multilayer microporous film includes a first layer containing ultra-high molecular weight polypropylene and high density polyethylene, formed on each side of a second layer containing ultra-high molecular weight polyethylene and high density polyethylene. In the first layer, 30% to 60% thereof is a region in which the polypropylene content is less than 20% as determined by AFM-IR from the displacement of an AFM cantilever measured between when laser is irradiated at 1465 cm-1 and when laser is irradiated at 1376 cm-1. For regions wherein the polypropylene content is 20% or higher, the mean of the maximum diameters is 0.1 μm to 10 μm. At 90° C., the film has an elongation at puncture of 0.40 mm/μm or greater.
