The invention discloses a preparation method of superfine fiber high-imitation grain synthetic leather. The preparation method comprises the following steps of: spinning sea-island composite fibers by utilizing nylon 6 and low-density polythene as raw materials, manufacturing non-woven fabric by utilizing the sea-island composite fibers, coating one surface of the non-woven fabric by utilizing high-solid-concentration polyurethane slurry, infiltrating the non-woven fabric by utilizing low-solid-concentration polyurethane slurry, enabling the non-woven fabric to pass through an aqueous solution of dimethylformamide after infiltrating, solidifying polyurethane and forming a cellular structure to obtain synthetic leather semi-finished products, enabling the synthetic leather semi-finished products to pass through methylbenzene to separate sea-component low-density polythene out of the sea-island fibers, peeling off the sea-island composite fibers to be superfine fibers, washing away methylbenzene through boiling water, and drying to obtain the superfine fiber high-imitation grain synthetic leather. The product manufactured by the method disclosed by the invention has the advantages of strong gradient, abundant hand feeling, fine and smooth surface wrinkles and strong toughness after being bent, and has the beneficial effects on aspects of pollution reduction, animal protection, ecological protection and the like.

Ultrasonically bonded laminated absorbent products comprising a liquid permeable top sheet, a liquid impermeable back sheet, an absorbent core positioned between the liquid permeable top sheet and the liquid impermeable back sheet, and an adhesive composition are disclosed. The laminated structure further comprising an embossed pattern stamped onto the liquid permeable top sheet, the liquid impermeable back sheet, the absorbent core, or any combination thereof. The adhesive composition comprises a mixture of atactic and isotactic polymers such that it has melt and flow characteristics similar to those of the topsheet and backsheet.

The edge of a construction element, such as a sandwich panel having a core and two outer layers, is closed such that forces acting on the construction element are directed to the outer layers and generally not through the panel core. A portion of the core may be removed to define a cavity within the construction element. A bonding material closes the edge by filling the cavity and forming a new edge that is substantially coplanar to the edges of the outer layers. The edge also can be closed by inserting the edge into a U-profile bracket and connecting the outer layers of the panel to side walls of the U-profile bracket.

Methods and apparatuses for forming a handling tab on a glass substrate are disclosed. The method may include conveying a glass substrate in a conveyance direction. An adhesive tape ribbon may be positioned adjacent to the first lateral edge of the glass substrate such that an adhesive surface of the adhesive tape ribbon is spaced apart from the first lateral edge of the glass substrate and the adhesive surface is substantially perpendicular to the first surface and the second surface. The adhesive tape ribbon may be folded such that at least a portion of the glass substrate is positioned between the adhesive surface of a first portion of the adhesive tape ribbon and the adhesive surface of a second portion of the adhesive tape ribbon, and a third portion of the adhesive tape ribbon forms a handling tab extending beyond the first lateral edge of the glass substrate.

The present invention relates to tissue engineering scaffolds (TE scaffolds) that mimic the biomechanical behavior of native blood vessels, tissue engineered blood vessels (TEBVs) derived from the TE scaffolds, and methods of making and using the TE scaffolds and TEBVs.

A method for manufacturing a polymeric article having an integrated reinforcing element. A thermoplastic material is introduced into a mould, after which reinforcing elements are inserted into the mould cavity. A second layer of the thermoplastic material is introduced into the mould, after which the mould is closed, pressing and heating the mould to melt the thermoplastic material and form the article. The thermoplastic layers may be provided in powder, sheet, or pellet form. The reinforcing elements may comprise reinforcing fibres or reinforcing fabrics. A polymeric track for a vehicle may be produced from this method.

The invention provides a high-precision pasting device and method based on CCD detection. The device comprises a product material strip feeding mechanism, a label material strip feeding mechanism, a pasting platform, a label sucking and pasting mechanism, a first CCD assembly, a second CCD assembly and a controller, wherein the first CCD assembly is arranged between a material tray assembly and the pasting platform and located above a product material strip moving path so as to shoot an image of a product material strip, and the second CCD assembly is arranged above a label taking station so as to shoot images of labels. The product material strip feeding mechanism comprises the material tray assembly, a material pulling roller and a servo motor driving the material pulling roller to rotate. The controller carries out contrastive analysis on the image of the product material strip and the images of the labels to control the label material strip feeding mechanism so that the labels can be accurately positioned at the label taking station. According to the high-precision pasting device and method based on CCD detection, the two CCD assemblies are adopted to shoot the image of the product material strip and the images of the labels respectively, contrastive analysis is carried out, and a label material strip is adjusted according to a comparison result so that the labels can be accurately positioned at the label taking station. In this way, the labels can be sucked and pasted at high precision, and the automation degree is high.

The structural layer or laminate comprises one or more synthetic polymers having film-forming properties, and the tissue-contacting layer of material contains tissue-reactive groups. The synthetic polymers having film-forming properties are preferably biodegradable polyesters, and the tissue-reactive groups are most preferably NHS-ester groups.

The invention discloses an HDPE(high-density polyethylene) membrane composited by high foaming of LDPE(Low-Density Polyethylene) and a preparation method of the membrane. The HDPE membrane composited by the high foaming of the LDPE comprises the HDPE membrane, wherein a sheet layer formed by the high foaming of the LDPE is arranged on the surface of the HDPE membrane, and a PE(Poly Ethylene) bonding layer is arranged between the HDPE membrane and the sheet layer; the sheet layer consists of the following components in percentage by weight: 95% of the LDPE, 3.5% of a nucleating agent, 1.39% of a foaming agent, 0.1% of an antisbrinking agent and 0.01% of an auxiliary addition agent. Compared with the prior art, the HDPE membrane composited by the high foaming of the LDPE is a novel environmental-friendly packaging material with high buffering capacity and shock resistant capacity, the membrane has the advantages that the flexibleness and the buffering capacity are good, the heat conductivity is low, the heat-shielding performance is excellent, the membrane does not pollute the environment, and the membrane belongs to the materials capable of being recycled.

An automatic tube-type specimen container supply apparatus includes a container storing box a bottom of which has a tapered surface having a container collecting position in a lowest part thereof to collect a plurality of tube-type specimen containers in one spot, a container individually-sending mechanism which lifts up the collected specimen containers one by one along one-side wall located close to the position, an outlet which allows the specimen containers to be discharged outside the box, and a container carry-out mechanism including a conveyor to automatically carry out the discharged specimen containers. The container individually-sending mechanism includes a lifting plate driven up and down and having a top end with a tapered surface. The tapered surface has a space to place only one specimen container lying on a side thereof and descending toward an outside of the container storing box.
