Described herein is a process for preparing a molded article including at least one structured surface, said process including applying a composition, preferably a foam material, into a mold having at least one structured inner surface and curing said composition to provide the molded structured article. The inner surfaces of the mold can be coated with a coating composition to obtain molded structured articles further including a flexible and durable coating layer. The present invention also relates to a structured molded article, preferably a shoe sole, which is obtained by the process.

The present invention relates to a method and a structure for attaching nonslip members to both sides of a sock, in which nonslip members having a variety of patterns may be firmly attached to an inner side and an outer side of a sock, which need a nonslip member, using a mold, the nonslip member includes air holes to be smoothly ventilated, and a size of the nonslip member is adequately adjusted according to a thickness and an area of the mold.

A shoe mold structure has a mold with a first end and a second end opposite to each other, an extending direction between the first and second ends is a longitudinal direction, the mold further has a mold cavity recessed inward from the second end and is composed of a bottom wall and side walls, each of the side walls defines a first side section, a second side section and a third side section connected in sequence along the longitudinal direction, the second side section is located between the first and third side sections, the first side section is closer to the first end than the third side section, the third side section is closer to the second end than the first side section, the second side section has an accommodating groove; and a heating unit disposed in the accommodating groove, and the heating unit provides heat energy.

The present invention generally relates to the printing of materials, using 3-dimensional printing and other printing techniques, including the use of one or more mixing nozzles, and/or multi-axis control over the translation and/or rotation of the print head or the substrate onto which materials are printed. In some embodiments, a material may be prepared by extruding material through print head comprising a nozzle, such as a microfluidic printing nozzle, which may be used to mix materials within the nozzle and direct the resulting product onto a substrate. The print head and/or the substrate may be configured to be translated and/or rotated, for example, using a computer or other controller, in order to control the deposition of material onto the substrate.

A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.

Methods and systems are disclosed for three-dimensional printing directly onto an article of apparel. Disclosed is a method and system for direct three-dimensional printing onto an article of apparel, including positioning at least a portion of the article on a tray in a three-dimensional printing system, the portion being positioned substantially flat on the tray, printing a three-dimensional material directly onto the article using a three-dimensional pattern, curing the printed material, and removing the article from the three-dimensional printing system.

A method of producing a reclaimed rubber made of recycled shoe material waste includes the following steps. Step S1: collect a scrap rubber which is the shoe material waste. Step S2: grind the scrap rubber to form scrap rubber granules. Step S3: devulcanize the scrap rubber granules to form a reclaimed rubber. A reclaimed material for manufacturing shoes includes a reclaimed rubber formulation and a crosslinking agent, wherein the reclaimed rubber formulation is constituted by compounding a basic rubber formulation and the reclaimed rubber, wherein the reclaimed material for manufacturing shoes includes 65-94.8 wt % of the basic rubber formulation, 5-30 wt % of the reclaimed rubber, and 0.2 wt % to 5 wt % of crosslinking agent. Mechanical properties of the reclaimed material for manufacturing shoes meet required standards of shoe outsole material. A method of consuming rubber waste produced during the shoe manufacturing process is disclosed herein.

A method for producing a water-tight, water-vapour-permeable segment, having a three-dimensional contour, for a shoe shaft, an item of clothing or a rucksack or for producing a shoe shaft, an item of clothing or a rucksack, the segment being free of connection points in its surface, and the method for producing the segment being a thermoforming process in which the two-dimensional flat structure obtained is completely laminated in its entirety, the segment being free of connection points in its surface. Also, a water-tight, water-vapour-permeable segment of a three-dimensional functional laminate for introduction into a shoe or shoe shaft, an item of clothing or a rucksack, the segment being dimensionally stable under its own weight, of a single piece and free of connection points in its surface.

The pressing of an article is achieved with a closed-loop feedback press. The closed-loop feedback press is effective to measure an amount of pressure applied and adjust the pressure to achieve a prescribed amount of compression on the article. Further, the press may leverage a closed-loop feedback system to maintain a consistent temperature of one or more platens. The press is able to adjust a pressure applied one or more times during a pressing operation to accelerate a temperature change in the pressed article while reducing the pressure applied as the temperature approaches a target temperature to limit unintentional deformation and bleeding of the pressed material of the article.
