Embodiments of the present disclosure provide a method of manufacturing a metal column using 3D printing technology. The method of manufacturing a metal column includes steps of: creasing a 3D-CAD design for printing the metal column; printing the metal column; pretreating the inner surface of a channel inside the metal column at low temperature; and coating the inner surface of the channel with a stationary phase so that the metal column is capable of separating a gas mixture into components.

Method of manufacturing a metal column

A plurality of channel elements provided in a bipolar plate have different widths depending on positions, so that the velocity of flow of the fluid increases from an inlet toward an outlet of the bipolar plate and water generated when the fluid is condensed on the downstream side of the bipolar plate can be discharged more smoothly. In addition, a plurality of channel elements have different contact angles depending on positions of the plurality of channel elements so that the contact angle increases toward the outlet side of the bipolar plate. Thus, the reaction gas can be more concentrated on the surface of a gas diffusion layer. Even if the concentration of the reaction gas is reduced at the outlet side of the bipolar plate, the diffusion of the reaction gas is well performed, so that performance reduction can be prevented.

The present invention provides fabrics with cut loop pile comprising a rayon core yarn and covering yarn of a split microfiber yarn and a manufacturing method thereof. The rayon core yarn at the section where said loops are cut is outwardly protruded from the covering yarn, wherein the rayon core yarn is separated into multiple filaments to function as hooks. The fabrics with cut loop pile show superior characteristics in polishing properties, sliding properties, water absorption properties, rapid drying properties and feeling of touch since polishing can be performed while easily catching foreign substances such as extremely minute dust particles or human hairs and the like by the hook-shaped rayon core yarn. Thus the fabrics with cut loop pile according to the present invention can be used usefully in products such as various kind of mats, towels, bathroom products, and the like including dishcloths and mops.

Fabric having cut-loop structure, method for manufacturing same, and product using fabric having cut-loop structure

The present invention provides fabrics with cut loop pile comprising a core yarn of a synthetic multifilament yarn and covering yarn of a split microfiber yarn and a manufacturing method thereof. The core yarn at the section where said loops are cut is outwardly protruded from the covering yarn, wherein the synthetic multifilament core yarn has been separated into multiple filaments to function as hooks. The fabrics with cut loop pile show superior characteristics in polishing properties, sliding properties, water absorption properties, rapid drying properties and feeling of touch since polishing can be performed while easily catching foreign substances such as extremely minute dust particles or human hairs and the like by the hook-shaped multifilaments of the core yarn. Thus the fabrics with cut loop pile according to the present invention can be used usefully in products such as various kind of mats, towels, bathroom products, and the like including dishcloths and mops.

Fabric material having cut loop texture, method of manufacturing same and product using same

The present invention provides fabrics with cut loop pile comprising a synthetic filament core yarn and covering yarn of a split microfiber yarn and a viscose rayon yarn and a manufacturing method thereof. The core yarn at the section where said loops are cut is outwardly protruded from the covering yarn, wherein the synthetic multifilament core yarn is separated into multiple filaments to function as hooks. The fabrics with cut loop pile show superior characteristics in polishing properties, sliding properties, water absorption properties, rapid drying properties and feeling of touch owing to the split yarn of microfibers and the viscose rayon yarn which comprises the covering yarn, and polishing can be performed while easily catching foreign substances such as extremely minute dust particles or human hairs and the like by the hook-shaped multifilaments of the core yarn. Thus the fabrics with cut loop pile according to the present invention can be used usefully in products such as various kind of mats, towels, bathroom products, and the like including dishcloths and mops.

An intelligent control system according to an exemplary embodiment of the present disclosure includes a plurality of network cameras to photograph a surveillance area; an image gate unit to perform image processing of image data, which is input from the plurality of network cameras, according to a specification that is requested by a user; a smart image providing unit to convert a plurality of image streams, which are image processed by the image gate unit, to a single image stream; and an image display unit to generate a three-dimensional (3D) image by segmenting, into a plurality of images, the single image stream that is input from the smart image providing unit and by disposing the segmented images on corresponding positions on a 3D modeling.
