A thin organic solvent resistant glove is disclosed including: a first polymeric layer in a shape of a glove including at least one of a blend of a polyisobutylene material and a nitrile-butadiene material, or a nitrile-butadiene material; a second polymeric layer in a shape of a glove including at least one of a polyisobutylene material or a blend of a polyisobutylene material and a nitrile-butadiene material, disposed on the first polymeric layer, and a third polymeric layer in a shape of a glove including a nitrile-butadiene material or an acrylic polymer material disposed on the second polymeric layer.

A method of making a garment material and garment material and garments obtainable by the method. The method comprises providing a first layer, which is a shaped polymer and applying a liner to the first layer, the liner being formed of yarn and having interstices through it. A fluid polymeric material is then applied to the liner so that it permeates the interstices and is allowed to solidify to thereby form a second layer in which the liner is embedded in the solid polymeric material. Fibres are then applied to form a textile layer, which serves as a skin-contacting layer. The garment material comprises a first layer (70, 76, 78), which is a shaped polymer; a second layer (80), which is a shaped polymer that is provided at one or more locations on the first layer, the second layer taking the shape of the first layer at said one or more locations; and a textile layer (82). The second layer is located between the first layer and the textile layer and a liner (22) is embedded in the second layer, the liner being formed of yarn and having interstices through it.

The invention relates to a method for recycling respiratory protection masks comprising a plurality of layers manufactured from a single thermoplastic polymer chosen from polypropylene, polyethylene terephthalate, polylactic acid, homopolymers and copolymers of polyamide 6 (PA6) and long-chain polyamides such as PA11 or PA12, and comprising a filtration layer made of polyvinylidene fluoride.

A system for automated manufacturing of apparel that includes a fabric dispenser operable to dispense a first web of fabric and a second web of fabric, the first web of fabric forming a front of an apparel and the second web of fabric forming a back of the apparel. The system includes an adhesive dispenser configured to apply discrete non-contiguous adhesive masses to the first web of fabric. The system includes one or more presses operable to join the first web and the second web along the side seams and shoulder seams of the apparel. The system further includes a cutting tool operable to make partial cuts to the first web of fabric along lines corresponding to a neck hole, bottom hem, and arm holes of the apparel located on the first web of fabric, the cutting tool further configured to cut the apparel out of a joined first web and second web of fabric by cutting along the side seams of the first web of fabric and the second web of fabric and cutting the bottom hem, the neck hole, and the arm holes on the second web of fabric.

The present invention provides a metal material and use thereof in preparing a metal model. The metal material comprises the following ingredients in percentage by weight: C0.06%, Si1.00%, 1.00%Mn4.00%, P0.045%, S0.005%, 20.00%Cr22.00%, 8.50%Ni10.50%, 1.00%Mos2.50%, 1.00%Cu3.50%, 0.20%N0.30%, with the balance being Fe; the pitting resistance equivalent number (PREN) of the metal material is calculated according to the formula: PREN=Cr %+3.3M0%+16N %, and the result is PREN30.0%

Provided is a method of additively manufacturing an object having a particle surface coating thereon, using an intermediate object produced in an additive manufacturing process by light polymerization of a dual cure resin, the intermediate object having residual dual cure resin from which it was produced remaining on a surface portion thereof in unpolymerized form; forming a solid particle coating adhered to the resin coating film; and then further curing the intermediate object.

A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

A custom cranial remodeling device to correct a deformed head of a subject comprises an inner layer shaped to contact the head of the subject at predetermined areas, the inner layer is deposited by an additive manufacturing device and an outer layer deposited by the additive manufacturing device. The inner layer and the outer layer are each formed by the additive manufacture device utilizing a device data file derived from a subject data file, the subject data file representative of the shape of the deformed head, the device data file determining the shape of the cranial remodeling device to correct the shape of the deformed head.

Methods, systems, and devices for manufacturing a wearable ring device are described. A printed circuit board (PCB) may be connected to an inner cover, where one or more apertures of the inner cover are aligned with one or more sensors of the PCB. Additionally, an injection molding process may be performed to fill a cavity between the inner cover and a surface of one or more molds with a filler material. The filler material may bind the PCB to the inner cover and fill the one or more apertures with the filler material, creating a ring assembly. Following the injection molding process, an outer cover may be placed around the ring assembly and one or more side covers may engage to secure the inner cover to the outer cover.
