Porous pvc or polyurethane sheet by dissolving out

Porous plastic materials are produced by (a) dispersing a solid, dissolvable filler in a thermoplastic polymer which is in a liquid or plastic state, (b) removing any solvent present by evaporation, (c) heating the product so that the polymer mixture is in plastic state, (d) forming the heated mixture into a sheet, and (e) removing the filler from the sheet by washing, without damaging the polymer material.

The polymer may be dissolved in a liquid which is a nonsolvent for the filler, to give a product which can be coated onto a removable paper base, which is removed after evaporation of the solvent.

Apparatus and method for finishing textile fabrics and silicone-coated textile.

Es werden eine Vorrichtung und ein Verfahren zum Ausrüsten von Textilien mit silikonhaltigen Ausrüstungsschichten vorgeschlagen, die sich dadurch auszeichnen, dass die fertigen Ausrüstungsschichten nicht geschlossen sind, sondern zahlreiche Poren aufweisen. Diese Poren können gemäss der Erfindung auf verschiedene Arten generiert werden und machen die neuen Textilien einerseits – wie von silikonbeschichteten Textilien bekannt – wasserabweisend, aber erstmals auch atmungsaktiv und wasserdampfdurchlässig. Durch die Atmungsaktivität und Wasserdampfdurchlässigkeit weisen die neuen Textilien einen stark erhöhten Tragekomfort auf. Zudem können die neuen Textilien den Träger vor kurzen Kontakten mit einer Flamme ebenso wie vor Konvektions- und Strahlungshitze schützten.

Percolative surface textured polymeric latex coating for a fabric supported glove and method of making

A latex dipped article, particularly a fabric supported glove which is flexible and fatigue resistant, comprising a fabric liner, with a shape of a hand. The fabric liner is coated with a foam polymeric latex material which is then treated with an aqueous silicone or non-silicon based surface active agent to facilitate the formation of percolative surface structure through bursting of bubbles in the foam layer and stripped off the excess polymeric material. Then the stripped material is removed gently by exposing to a flowing fluid which further enhances the texture of the percolative coating that results an excellent grip in dry, wet and oil environments.

Multi-layered coated fabric for personal protective equipment

A coating fabric and method of manufacturing the same are provided. A coated fabric includes a base coating layer. The base coating layer defines a smooth coating to resist liquid penetration to the fabric. The coated fabric also includes a middle foam coating layer that is deposited on at least a portion of the base coating layer. The middle foam layer defines a middle layer foam density and is configured to absorb at least a portion of liquid. The coated fabric further includes an outer foam coating layer that is deposited on at least a portion of the middle foam coating later. The outer foam layer defines an outer layer foam density and is configured with holes to allow liquid to penetrate to the middle foam layer. The middle layer foam density is less than the outer layer foam density. A corresponding method of manufacturing is also provided.

Napped artificial leather and method for producing same

Disclosed is a napped artificial leather napped including: a non-woven fabric that is an entangle body of ultrafine fibers; and an elastic polymer impregnated into the non-woven fabric, the napped artificial leather having, at least on one side thereof, a napped surface formed by napping the ultrafine fibers, wherein the ultrafine fibers contain 0.5 mass % or more of a pigment (A), the elastic polymer contains 0 to 0.01 mass % of a pigment (B), and the ultrafine fibers and the elastic polymer are undyed; the napped surface has a lightness L* value of 25 or less in a color coordinate space (L*a*b* color space); and a ratio of an area occupied by the elastic polymer, observed on the napped surface, to a total area of an area occupied by the ultrafine fibers and the area occupied by the elastic polymer is 0.5% or less.

Multifunctional latex article

A multi-layered multifunctional polymeric latex article is provided. A first polymeric latex layer, having nitrile butadiene, is resistant to chemical permeation whilst the second polymeric latex layer disposed on the first layer, being a composite layer of polychloroprene and Nano clay, is resistant to chemical degradation. The third layer disposed on the second layer is a polychloroprene layer having a unique micro-roughened surface texture pattern, providing an improved grip and friction in both wet and dry conditions. The second and third layers are disposed during the wet gelled stages of the first and second layers respectively. The gelled third layer is dipped in a solvent mixture whereby a chemical reaction causes the gelled surface of the third layer to texturize by swelling and fixing, creating a continuous and discontinuous wavy micro-roughened surface which is then cured causing formation of ionic crosslinks in the third polymeric layer.
