Non-toxin adhesiveless slipper includes an upper portion and a lower portion; wherein the upper portion and the lower portion are bonded with each other by an adhesive film. A processing method for bonding an upper portion and a lower portion together, including steps of: a. heat melting the EVA and the EAA to form a fluid compound, and blowing the fluid compound on a bottom surface of the upper portion to form an adhesive film; b. placing an isolated paper on the adhesive film; c. placing the upper portion into a heat-pressing machine to ensure the adhesive film and isolated paper securely attached on the bottom surface of the upper portion; d. placing a rubber sheet on a mold to process a heat pressing and then removing the remaining rubber on the contours of the mold to form the lower portion; e. placing the upper portion and the lower portion into a sectional die, and then processing the heat-pressing.

A production method of glueless pasted integrally modeling sole comprising the following steps: taking a rubber outsole compound in a mold to perform partial vulcanization; taking a midsole compound in the mold to simultaneously perform pressurizing and heating together with the rubber outsole compound that has been partially vulcanized to simultaneously generate more vulcanization of the rubber outsole compound and foaming reaction of the midsole compound and occurring adhesion; and completing glueless adhering and pasting for the rubber outsole and the foaming midsole after the mold is cooled down so as to obtain a sole finished product. Accordingly, it can greatly reduce the procedure of forming soles, decrease labor force at great quantity and energy use, and reduce the proportion of producing waste and also achieves the efficacies of reducing costs and energy saving and carbon reduction at the same time.

A method of manufacturing an article that includes providing an element formed of an elastomeric material or composite; placing the surface of the element in contact with a substrate; and affixing the element to the substrate. The element includes an uncured, partially cured, or fully cured UV radiation curable elastomeric material and optionally one or more regions of an adhesive material. The element is affixed to the substrate while the surface of the element is in contact with a surface of the substrate by increasing a temperature of at least a portion of the element, applying pressure to at least a portion of the element, or exposing the uncured or partially cured UV radiation curable material to UV radiation in an amount and for a duration of time that is sufficient to partially cure the uncured material or to fully cure the partially cured material.

A method for producing a shoe includes: preparing an adapter including a first thermoplastic and an energy absorber having a higher dielectric loss factor than that of the first thermoplastic, the adapter having the first thermoplastic exposed at least on a first surface; a contacting process of bringing a first bonded surface formed on a first shoe member into abutting contact with the first surface and bringing a second bonded surface formed on a second shoe member into abutting contact with the second surface; and of heating and melting the adapter by irradiating the adapter with microwaves after the contacting process to cause these shoe members to be bonded to each other via the adapter. A shoe can be produced by the method.

The invention provides a method for assisting a joining of a vamp and a sole by vacuum positioning. Initially, the method is that placing a shoe last in a vamp to be joined, coating a liquid medium to a side of the vamp to be joined with a sole or a side of the sole to be joined with the vamp, and combining the vamp with the sole. Afterward, placing the vamp and the sole in a bag, performing a vacuum operation on the bag to press the vamp and the sole, performing a microwave heating operation on the bag to heat the liquid medium to make the vamp join with the sole, and finally taking out the joined vamp and sole from the bag to obtain a finished product.

The present technology relates generally to a footwear assembly and method of manufacturing said footwear assembly. The footwear assembly includes an outsole and an upper connected to the outsole, where the upper includes a neoprene sock, a vulcanized rubber layer, and an injection molded layer. The neoprene sock is a full-foot neoprene sock having a foot portion that is configured to receive a wearer's foot. The vulcanized rubber layer fully covers a vamp portion, heel portion, toe portion, and ankle portion of the neoprene sock while only covering some of an underfoot portion. The injection molded layer is formed over a portion of the vulcanized rubber layer and completely covers the underfoot portion of the neoprene sock.

An article of apparel or sporting equipment, such as garments and footwear incorporates a molded component formed of a UV radiation curable material. In the case of an article of footwear, the UV radiation curable material may be formed into an outsole. The method of manufacturing such articles include placing an ultraviolet radiation curable material in contact with a molding surface; conforming the UV radiation curable material to a shape of the molding surface, forming a molded component; and removing the molded component from the molding surface, such that the component maintains the shape of the molding surface. The molded component may be exposed to ultraviolet radiation in an amount and for a duration that is sufficient to partially cure or fully cure the UV radiation curable material.
