A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.

The present invention relates to a process for preparing a surface treated filler material product with succinic anhydride(s), a surface treated filler material product, a polymer composition, a fiber and/or filament and/or film and/or thread comprising the surface treated filler material product and/or the polymer composition, an article comprising the surface treated filler material product and/or the polymer composition and/or the fiber and/or filament and/or film and/or thread as well as the use of a mono-substituted succinic anhydride for decreasing the hydrophilicity of a calcium carbonate-containing filler material surface and the use of a surface-treated filler material product for initiating the crosslinking reaction in epoxide resins.

Aqueous formulations containing antimicrobial materials dispersed in solutions or emulsions, methods of their preparation, application of such compositions to surfaces, and their resulting coatings. Coating of hydrophobic surfaces with aqueous solutions or suspensions containing antimicrobial materials are disclosed. Several applications of the antimicrobial coatings are described including the coating of solid and porous substrates such as fabrics which may be used for gowns, masks, and other personal protection equipment.

Provided are staple fibers for air laid capable of improving dispersibility, and a method for producing the same. The staple fibers for air laid are characterized by including stable fibers to which a fiber treatment agent containing a hydrophilic oil agent and a silicone-containing oil agent is adhered in an amount of 0.7 to 2 wt % of a weight of the staple fibers, wherein a weight ratio of the hydrophilic oil agent and the silicone-containing oil agent contained in the fiber treatment agent (a weight of the hydrophilic oil agent/a weight of the silicone-containing oil agent) is within a range of 60/40 to 90/10, and a moisture content is 2 to 13%.

Provided is a colored polypropylene resin composition, which is excellent in high color developability, washing resistance, and sublimation resistance, and can be stably supplied. The colored polypropylene resin composition includes a polypropylene resin and a colorant, and is characterized by including a compound having a predetermined structure as the colorant.

The present disclosure provides a photochromic thermal insulation fiber including a core layer and a sheath layer covering the core layer. The core layer includes about 99 parts by weight to 100 parts by weight of polypropylene and about 0.4 parts by weight to 0.6 parts by weight of a photochromic dye. The sheath layer includes about 98 parts by weight to 99 parts by weight of nylon and about 1 part by weight to 2 parts by weight of a near-infrared reflecting dye.

Methods of producing composite articles and composite articles are disclosed herein. A method of producing a composite article includes providing a nonwoven fabric substrate having a surface. In some embodiments, the method may include electrospinning a nylon solution on the surface of the nonwoven fabric substrate to coat and/or impregnate the nonwoven fabric substrate with a nylon fiber.

Disclosed is a textile sliding surface with a functional layer (1) and a base layer (2), which are connected to each other by filament yarns. The functional layer (1) is formed of pile loops, whereby the height of the pile loops in the functional layer (1) has a height (4), depending on the sport, in the range 4-1 4 mm and the functional layer (1) has 400-2400 pile loops per dm.sup.2. The yarns are bound into the base layer (2) in the lower part of the pile loops by W-bonds (10).

Extensible nonwoven fabrics having improved elongation, extensibility, abrasion resistance and toughness. In particular, embodiments of the invention are directed to extensible spunbond fabrics comprising a polymeric blend of a metallocene catalyzed polypropylene, polyethylene, and a third polymer component.

Disclosed herein are improvements to processes and equipment for the manufacture of composite nonwoven webs comprising a mixture of two or more different fibers and formed from at least two streams of air-entrained fibers. Adjacent the perimeter of an exit port of one of the fiber streams are located a series of spaced tabs and apertures. As a first stream of air-entrained fibers pass the series of tabs and apertures, vortices are formed therein. When mixed with a second stream of air-entrained fibers, the vortices within the first stream of fibers causes increased mixing of the fibers, helping to drive the first fibers deeper into the second stream of air-entrained fibers.
