A continuous wire drive system for a needleless electrospinning apparatus, the electrospinning apparatus including an electrospinning enclosure and within which a nanoscale or submicron scale polymer fiber web is formed onto a substrate from a liquid polymer layer coated onto a plurality of continuous electrode wires passing through the electrospinning enclosure. The continuous wire drive system includes a master wire drive drum and a slave wire drive drum, each of the master wire drive drum and slave wire drive drum including a plurality of wire guides, each of the wire guides including a channel or groove for receiving one of the plurality of continuous electrode wires. The continuous wire drive system is external to the electrospinning apparatus, and the continuous wire drive system drives the plurality of continuous electrode wires through the electrospinning enclosure.

A midsole for an article of footwear including a three dimensional mesh including interconnected unit cells and methods of making the same. The interconnected unit cells each include a plurality of struts defining a three dimensional shape. The interconnected unit cells are connected at nodes having a valence number defined by the number of struts connected at that node. The valence number of the nodes may vary to provide customized characteristics to zones or portions of the midsole. The plurality of interconnected unit cells may be organized in a warped cubic lattice structure. The warped cubic lattice structure and the size/shape of interconnected unit cells may vary to provide customized characteristics to zones or portions of the midsole. The three dimensional mesh may be customized based on a biometric data profile for an individual, or group of individuals. The midsole may be manufactured using an additive manufacturing process.

Provided is a shoe including an upper composed of a fiber sheet, the fiber sheet including: a base sheet including yarns having heat shrinkability; and a plurality of chip members, each of which is a sheet having an area smaller than that of the base sheet, the base sheet and the plurality of chip members being layered and joined together.

Floor coverings, such as modular panels or tiles, for installation on interior surfaces include one or more layers, for example, an upper wear layer and a backing layer, where at least one layer includes a filler that includes a carbon negative material, such as concentrated carbon. The carbon negative material can sequester carbon such that the resulting floor covering has a negative carbon footprint when subjected to a Life Cycle Assessment.

A sandal having releasable strap fastening, comprising a sole, at least one strap and at least one clamping buckle and/or at least one anchor buckle. According to the invention, the sandal is modularly constructed and can be easily assembled and disassembled. The sole and the at least one strap are connected to each other by guiding the at least one strap through eyes provided in the sole. The two ends of the at least one strap, which form two strap ends, are either fastened to the strap again by means of at least one of the clamping buckles so as to form a loop or are anchored to one of the eyes by means of at least one of the anchor buckles.

An article of footwear is disclosed that includes an upper, an outsole, and a midsole. The upper is configured to receive a foot, and the outsole is secured to the upper. The outsole defines a plurality of apertures extending entirely through the outsole. In addition, the outsole has a ground-engaging surface positioned at a first elevation. The midsole is positionable such that a lower surface of the midsole extends into the apertures of the outsole and is exposed by the apertures.

An article of footwear is disclosed that includes a sole structure having a bladder element. The bladder element includes multiple fluid-filled tubes that are substantially decoupled from one another along their respective lengths. The tubes extend lengthwise at least partially from a lateral extremity of the sole structure to a medial extremity of the sole structure. A method of manufacturing a sole structure of an article of footwear includes forming a bladder element with multiple tubes substantially decoupled from one another along their respective lengths. The method includes positioning the bladder element so that the tubes extend lengthwise at least partially from a lateral extremity of the sole structure to a medial extremity of the sole structure.

In one aspect of the disclosure, a knitted component for use in an article of footwear may include a first layer with a multi-bed first area having a first surface and an opposite facing second surface. The knitted component may include a second layer with a second area overlapping the first area. The second area may have a first surface and an opposite facing second surface. The knitted component may include a plurality of interlayer knit stitches interlooping at least one yarn of the first layer with at least one yarn of the second layer at an interface between the second surfaces of the first and second areas. The interior surfaces of the first area and the second area may define at least part of a freely separable area between the first and second areas.

The present invention provides a shoe material part mainly composed of a coffee ground material, a porous material and a rubber-plastic material, and is made of a recycled waste porous material and recycled waste coffee grounds, which can improve the value of waste recycling and reuse, and reduce environmental pollution, in addition to reducing waste, there will be no residue pollution of natural ecology and other issues in the subsequent environmental recycling, quite in line with environmental requirements. In addition, the present invention has the function of natural deodorization, because the coffee grounds can naturally diffuse the aroma of coffee, and the characteristics of better deodorization and air permeability of the coffee grounds can be used to reduce the foul smell of a user's foot.

The present invention provides synthetic fibres with advantageous properties such as high tensile strength and which can be produced by recombinant biotechnological means. The invention also provides the constituent components from which the fibres are assembled, along with fabrics formed from the synthetic fibres. Items comprising the fibres and fabrics of the invention are also included.
