The present disclosure provides an upper for an article of footwear. The upper may include a knit element defining a portion of at least one of an exterior surface of the upper and an opposite interior surface of the upper. The interior surface may define a void. A tongue and the knit element may have a common yarn, and the tongue may extend through a throat area of the upper. The tongue may comprise a lateral edge, a medial edge, and a forward portion. At least one of the lateral edge, the medial edge, and the forward portion may be unsecured to the knit element. The tongue may be secured to the knit element at least at one of the lateral edge, the medial edge, and the forward portion of the throat area.

A fabric case for an electronic device may include a back panel having a periphery and a side wall that extends around the periphery. The back panel may include a knit image of a user-selected digital photograph or other design. The design of the back panel may be customized according to the user's tastes. The case may be formed using computing equipment and knitting equipment. The computing equipment may receive a digital image from the user and may reduce the resolution and the number of colors in the digital image according to the specifications of the textile machine. Fabric pattern design software may convert the digital image into knitting instructions. The knitting instructions may be executed by knitting equipment to produce a custom back panel having a knit image of the digital photograph. The back panel may be attached to a peripheral side wall to form the fabric case.

A knitted fabric having a heat generating function has a four-layer structure and can be knitted by a flat knitting machine. Knit stitching is used to knit first and second layers such that the second layer is fully covered under the first layer. Tuck stitching is used to knit the third layer such that one stitch is made to the third layer per a preset number of stitches made to each of first and second layers. Knit stitching is used to knit the fourth layer. After knitting, the fabric is soaked with water and spin-dried to form protrusions, spatially distributed as a centered rectangular lattice, on fabric surface. The second layer is electrically conductive for generating heat and is hidden inside the fabric. This layer is not easily hooked by a user during use and cleaning. The fabric is elastic and soft, and provides a comfortable feeling to the user.

The present disclosure provides an upper for an article of footwear. The upper may include a knit element defining a portion of at least one of an exterior surface of the upper and an opposite interior surface of the upper. The interior surface may define a void. A tongue and the knit element may have a common yarn, and the tongue may extend through a throat area of the upper. The tongue may comprise a lateral edge, a medial edge, and a forward portion. At least one of the lateral edge, the medial edge, and the forward portion may be unsecured to the knit element. The tongue may be secured to the knit element at least at one of the lateral edge, the medial edge, and the forward portion of the throat area.
