The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to articles with a plurality of interconnected chambers that are configured to retain a thermally insulating fill material such as down or synthetic fibers. The plurality of interconnected chambers are formed between at least two layers of material and between a plurality of seams. The plurality of seams are configured to join the at least two layers of material together. In one aspect, each seam of the plurality of seams is angularly oriented with respect to an adjacent or neighboring seam of the plurality of seams. One or more openings or perforations may be formed on one or more seams of the plurality of seams forming the plurality of interconnected chambers. The one or more openings may achieve evaporation of moisture and/or air transfer from an interior environment of the garment to an exterior environment.

Cutting of a material, such as a textile or film, can damage the material. A tool is provided that utilizes vacuum pressure near a knife edge to increase a result of the cut. The vacuum pressure passes through a base portion of the tool that has a recessed portion effective to distribute vacuum pressure to one or more apertures extending around an insert of a core portion. The one or more apertures align with a void between the knife edge and the insert allowing for the void to transmit the vacuum pressure through the tool to the knife edge. A machine horn may then cut the material at the knife edge and couple the material with another material.

Disclosed is a method of manufacturing a thermoplastic synthetic resin product, including preparing a mold having a cavity formed in a predetermined shape; filling the cavity of the mold with a thermoplastic synthetic resin material in an amount greater than the volume of the cavity of the mold; heating the mold under pressure; releasing the pressure when the thermoplastic synthetic resin material charged in the cavity of the mold is melted by heating, and opening the mold; removing, of the melted thermoplastic synthetic resin material in the opened mold, the material other than the material charged in the cavity of the mold; placing either a fabric or a hot melt on the mold having the cavity filled with the thermoplastic synthetic resin material; and cooling the mold under pressure, thus integrating either the fabric or the hot melt with the thermoplastic synthetic resin material in contact with either the fabric or the hot melt.

Disclosed are a method and/or a system of stitchless bedding. In one aspect, a bedsheet component includes a fabric having an angled corner area. A marginal border is folded to include a top marginal fold and a bottom marginal fold. The top marginal fold is aligned to be substantially parallel with the bottom marginal fold. An adhesive is inserted between the top marginal fold and the bottom marginal fold. A heat and/or a pressure is applied to the top marginal fold and/or the bottom marginal fold to soften the adhesive. The adhesive further permeates a portion of the top marginal fold and a portion of the bottom marginal fold. The top marginal fold and the bottom marginal fold are held together as a single, complete flexible unit when the adhesive is cured.

A method for applying a thermoreactive seam tape to a seam is provided. The thermoreactive seam tape may be positioned adjacent to the seam, which may include a first fabric surface and an adjacent second fabric surface. The thermoreactive seam tape may include an interior planar surface that engages both the first fabric surface and the second fabric surface of the seam. The thermoreactive seam tape may further include an exterior surface opposite the interior surface, where the exterior surface is substantially non-planar with respect to the interior planar surface along a length of the thermoreactive seam tape. Heat and pressure may be applied to the thermoreactive seam tape, wherein the heat and the pressure facilitate adhesion of the thermoreactive seam tape to the first fabric surface and the second fabric surface of the seam.

A control method of an ultrasonic welding system comprises: detecting operation of the ultrasonic welding system immediately while the ultrasonic welding system is in a working state; acquiring a current working frequency of an ultrasonic generator in the ultrasonic welding system while the ultrasonic welding system is detected to complete a preset first operation every time; determining a current frequency searching range of the ultrasonic generator according to the current working frequency of the ultrasonic generator; controlling the ultrasonic generator to search for an anti-resonance point in the current frequency searching range; and adjusting the working frequency of the ultrasonic generator to be an anti-resonance point while the anti-resonance point is searched in the current frequency searching range.

A composite material formed by combining a polyurethane material with an unclickable foam layer and a scrim layer through roll and flat form technology. The composite material is embossed to form pillowlike chambers or cells delineated by a network of emboss pattern lines formed by the bonding between these layers.

A hybrid mold includes (a) an Invar® eggcrate structure, (b) an Invar® interim working surface and (c) a CF composite material overlay. The eggcrate and interim working surface are welded or otherwise connected together to form a unitary base mold. The CF overlay is bonded to the interim working surface. The CF overlay is easily reconfigurable and can be replaced without destroying the integrity of the base mold.

A fibrous preform (1) is produced, provided with a sandwich structure comprising an intermediate flexible core (4) and two outer fibrous frames (2, 3), respectively arranged on opposing outer faces of said flexible core (4) and assembled by sections of wire (8, 9) passing through said fibrous frames (2, 3), said preform (1) being impregnated with resin. Said preform is then hardened and the core (4) is removed, preferably by pre-densification with chemical vapour infiltration, and the structure produced is then densified with liquid-phase infiltration.

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having enhanced flexural properties, which correlates to low composite backface signature. The composites are useful for the production of hard armor articles, including helmet armor.
