A headgear or headgear segments are manufactured to shape thereby producing little or no waste material. Such headgear or headgear segments (components) may comprise a unitary, substantially seamless structure. Techniques such as knitting, braiding, crocheting, and 3D printing may be used to produce the headgear. As a result, the manufacturing process may have reduced steps, the amount of material waste may be reduced, and there are virtually no seams in the headgear between adjoining sections, thereby resulting in headgear with enhanced comfort.

A seat back for an office chair includes a knit material for extending over a structural frame. The knit material can be formed in a single knitting operation to include cushioning characteristics that vary across different regions of the knit material. The knit material may be a weft knit material having a first layer, a second layer, and a third layer, wherein the third layer is inlayed between the first and second layers and the inlay material is different from at least the first and second layers and provides a degree of cushioning between the first and second layers. The first and second layers are knit according to a predetermined pattern, the predetermined pattern determining crossing lines where the first and second layers cross one another and fix the third layer in position with respect to the first and second layers. The predetermined pattern is differentiated between regions of the back support, such that a first region of the back support has a higher density of crossing lines than a second region of the back support, the first region providing a different degree of cushioning than the second region.

A knitted fabric for promoting heat dissipation is to be an insole and covers a wearer's skin when in use, and has two surface layers, an intermediate layer, and multiple channels. The two surface layers are disposed at a spaced interval, and include a first surface layer and a second surface layer oriented to the wearer's skin when the knitted fabric is in use. The second surface layer has multiple braids disposed parallelly, and each one of the multiple braids is straight and extends in a widthwise direction. The intermediate layer is formed with multiple monofilaments knitted between the two surface layers and divergently stretch out from each braid toward the first surface layer. Each monofilament intercrosses with another at a point near the first surface layer. A channel is formed among the intermediate layer and adjacent two said braids and has a V-shaped cross section.

A fabric structure includes a first layer, a second layer, and a spacing layer that interconnects the first layer and the second layer, wherein, the interconnecting of the first layer, second layer, and third layer forms a plurality of channels.

An upper-torso garment includes a tubular-jacquard knit structure within a chest-covering portion. The tubular-jacquard knit structure includes interlocked courses formed by each front-stitch course intermittently interlocking with a back-stitch course. The tubular-jacquard knit structure is divided into a plurality of zones across the chest-covering portion, and the zones may include different versions of the tubular-jacquard knit structure based on how front-stitch courses interlock with back-stitch courses.

Three-dimensionally knitted noble metal gauzes, or sections of such gauzes, for carrying out catalytic reactions of fluids are knitted in two or multiple layers and the meshes of the individual layers are connected to one another in one form by a pile thread or multiple pile threads, so that the noble metal gauze has a tertiary structure.

The present invention relates to a shoe including an upper, the upper including an instep cover that covers the instep of a foot. The instep cover includes an instep cover body and a tongue. Two or more protrusions that are configured to extend in use from the instep cover body toward the foot are located at least in a region between the MP joint and the talus in a side portion of the instep cover body. The protrusions are made of embroidery. The protrusions have a height of 0.5 mm or more, a width of 2 mm or more, and a length of 2 mm or more. A distance between each pair of the adjacent protrusions is 2 mm or more in part of the region. The shoe of the present invention includes the upper that improves the heat dissipation properties without impairing the contact between the foot and the shoe.
