11560687 · 2023-01-24 ·

The present invention relates to a below grade, blind side, improved dual waterproofing membrane assembly incorporating a secondary membrane comprising of a bentonite sheet waterproofing layer, and a primary membrane comprising of a sheet membrane having an adhesive to fully bond to a concrete/shotcrete. The invention encompasses a dual layer or dual membrane system that acts as a barrier, and prevents, and blocks water and moisture, from passing from one side of the structure to the other side. The dual barrier layer system can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The invention can be used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table, or a constant hydrostatic pressure, or high ground moisture, that may creep into a foundation or a wall.

20230226795 · 2023-07-20 ·

A multi-layered product having an embossed interior layer is disclosed along with a method of making the product. The multi-layered product has a first layer with an interior surface, a second layer with an interior surface, and a third layer sandwiched between the first and second layers. The third layer has a first surface and a second surface and has a thickness therebetween. The third layer is embossed into a waffle pattern having a plurality of protrusions and a plurality of recesses. Each of the plurality of protrusions and recesses is adjacently aligned and horizontally offset from one another. The plurality of protrusions forms a horizontal plane, at the first surface, which is positioned above a horizontal plane formed by the plurality of recesses, at the first surface. The product also has an adhesive which secures the three layers together.

Fluorine-containing mixture material and fluorine-containing super-oleophobic microporous membrane using same as raw material, and preparation method therefor and use thereof

This disclosure provides a fluorine-containing mixture and a fluorine-containing super-oleophobic microporous membrane using the fluorine-containing mixture as a raw material, as well as preparation methods and applications for the fluorine-containing mixture and the fluorine-containing super-oleophobic microporous membrane. The fluorine-containing mixture of the present disclosure comprises, by weight percentage, the following components: Component A: 50%˜90%; Component B: 3%˜25%; Component C: 0%˜35%; Component D: 0%˜3%; wherein Component A comprises high molecular weight polytetrafluoroethylene homopolymer or copolymer dispersion resin; Component B comprises one or more fluorine-containing alkyl acrylate monomers; Component C comprises one or more fluorine-free acrylates; Component D comprises high temperature free radical initiator. There's no need to add inflammable or explosive lubricating oil, making the process highly safe; and the obtained fluorine-containing super-oleophobic microporous membrane has high waterproof, air-permeable, oil-resistant and washable performance, in line with the needs of a new generation of waterproof and air-permeable protective clothing.

Sound absorbing material

The sound absorbing material according to the present invention is formed by laminating a porous sound absorber and two or more sheets of a nonwoven fabric one on another. The nonwoven fabric has a plurality of drawn filaments arranged and oriented in one direction. The mode value of the diameter distribution of the plurality of filaments is in the range of 1 to 4 μm. The grammage of the nonwoven fabric is in the range of 5 to 40 g/m.sup.2. The sound absorbing material according to the present invention provides high sound absorption performance in a predetermined low frequency band of 6000 Hz or less, and still remains light in weight and flexible enough and easy enough to handle to be substantially comparable to the porous sound absorber.

Method of forming an article of apparel

An article of apparel includes a composite material. The composite material includes a pliable first layer and a resilient second layer, where the first and second layers are secured to each other via a patterned strand network. In forming the composite material, the second layer is stretched and maintained under tension while the first layer is secured to the second layer via the patterned strand network. The tension on the second layer is then released, resulting in contraction of the second layer in relation to the first layer and an outward buckling or protrusion of the first layer in relation to the second layer to form protruding cells along the composite material that are bounded by portions of the patterned strand network. The patterned strand network can be formed using embroidery with one or more auxetic patterns in the stitching.
