Ballistic protection material and use thereof
11578950 · 2023-02-14 · ·

The present invention relates to a protective material, preferably a ballistic protection material, having a protective function against ballistic active bodies (launch bodies), in particular against reinforcement-penetrating and/or armor-piercing projectiles, thrust bodies or penetrating bodies, and to the use thereof.

HIGH MODULUS, HIGH THERMAL CONDUCTIVITY RADIATIVE PASSIVE COOLANT

A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m.sup.2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.

Medical protective clothing materials

Protective clothing materials and related methods and garments are provided. In some embodiments, a protective clothing material may comprise a fibrous layer that serves as a barrier to certain fluids (e.g., bodily fluids, water) and microbes. The impermeability of the fibrous layer may be due, at least in part, to the structural uniformity and/or relatively small pore size of the fibrous layer. In some embodiments, the fibrous layer may have a relatively high air permeability that imparts beneficial properties (e.g., relatively high air flow, breathability) to the protective clothing material without adversely affecting its protection rating. In certain embodiments, the protective clothing material may also comprise one or more coarse nonwoven webs that impart beneficial properties (e.g., splash resistance) to the protective clothing material. The protective clothing materials, described herein, may be particularly useful for a wide variety of applications, including the formation of AAMI level 4 protective garments.

A NEW MULTI-LAYER INTERLINING AND THE PRODUCTION PROCESS THEREOF

Disclosed is a new multi-layer nonwoven interlining and the production process thereof. The process allows a multi-layer nonwoven interlining to be obtained simultaneously with a single process on a single production line. The process includes a fiber opening step, a fiber feeding step, a carding step, a levelling step of the additional layer by the thermal treatment, and a point bonding step of the carded web and additional layer. As a result of the process, a structure is obtained where the carded web is point-bonded onto the additional layer.

ANTI-PROPYLENE MASK AND METHOD FOR PREPARATION THEREOF
20230211190 · 2023-07-06 ·

An anti-propylene mask and method for preparation thereof is provided; the anti-propylene mask includes a fiber cloth contact layer, an antistatic non-woven fabric layer and a fullerene/nano titanium dioxide spunbond layer which are arranged in sequence; the fullerene/nano titanium dioxide spunbond layer is made by spun-bonding the modified resin material into a fiber web; the raw materials of modified resin materials include matrix resin, carboxylated fullerene derivatives, nano titanium dioxide, a lubricant, and a coupling agent; the modified resin material is prepared by following method: the carboxylated fullerene derivative is mixed and reacted with the nano titanium dioxide to prepare the carboxylated fullerene derivative-modified nano titanium dioxide, which is then blended and extruded with the remaining components in the raw material, and thus prepared. The mask can prevent propylene from entering the human body through the human respiratory organs and has a good anti-propylene effect.

Methods of disassembling apparel products having shape memory adhesives

Embodiments provide methods of disassembling an apparel product. The methods include exposing an adhesive of the apparel product to heat or electromagnetic energy. The adhesive is disposed at least partially disposed between a major component and a minor component of the apparel product. The adhesive includes a shape memory material. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.

COMPOSTABLE LID FOR SEALING A BEVERAGE CAPSULE OR A BEVERAGE PAD AND CAPSULES AND PADS SEALED THEREWITH

This invention relates a compostable lid for sealing a beverage capsule or a beverage pad wherein the lid comprises a natural-fiber based support obtainable by: (i) providing a first fibrous base sheet comprising natural fiber material sensitive to a gelatinizing agent; (ii) treating the first base sheet with a gelatinizing agent to give a treated first fibrous base sheet comprising gelatinized material; (iii) providing a second fibrous base sheet; (iv) contacting the treated first fibrous base sheet and the second base sheet with each other; (v) causing at least partial migration of the gelatinized material from the treated first fibrous base sheet into the second fibrous base sheet to give a multilayer product; and (vi) neutralizing and/or washing the product thus obtained and then drying it.

HYBRID SIDE RAIL ASSEMBLIES AND MATTRESSES INCLUDING THE SAME

A side rail assembly and a mattress assembly including the side rail assembly about at least a portion of a perimeter of the mattress assembly. The side rail assembly includes a laminate structure including one or more foam layers and one or more fiber layers in a stacked arrangement. The fiber layer can be a non-woven layer.

Water barrier exterior sheathing panel

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier sheet are also provided. An exterior sheathing system employing the exterior sheathing cementitious panel is provided.

Cross layer fiber entanglement to increase strength of 3D part
11485110 · 2022-11-01 · ·

A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.
