A flying woven vamp based on ergonomic fit to the contour of the foot and its production method

Abstract

The invention relates to a flyknit vamp based on human engineering and attached to the contour of a foot upper surface and a production method of the flyknit vamp. Production is performed on a double-needle bar flat knitting machine, a shoe tree with a standard size is divided into multiple featured three-dimensional curved surfaces attached to the contour of the foot upper surface, a tree attaching method is adopted for spreading two-dimensional planes of the three-dimensional curved surfaces, then a local knitting technology is used for rotating, aligning and knitting the two-dimensional planes into a three-dimensional curved surface approximately attached to the foot upper surface in shape. According to the production method, textured paper is bound to the shoe tree with the standard size, redundant protruding parts are cut off, the contour of the textured paper after cutting is used as a local knitting splitting basis, rotating, aligning and local contour correcting are performed on the textured paper based on a flat knitting principle, and finally the vamp is attached to the contour of the foot upper surface. Like a bare foot, comfort and freedom are realized, foot pressure isreduced, and the flyknit vamp is in accordance with a natural healthy motion conception of the bare foot feeling in human engineering.

Description

technical field [0001] The invention belongs to the technical field of knitted shoe weaving, and in particular relates to a fly-knit upper based on ergonomics and fits the contour of the instep and a production method thereof. Background technique [0002] With the prevalence of the concept of natural movement, the scientific concept of barefoot exercise gradually emerged. People gradually realized that modern sports shoes more or less limit the control of human feet, making it impossible to maintain the normal position of the feet. Some shoes The design instead interferes with the movement of the foot. Therefore, in the design of shoes, it should be considered to distribute the pressure of the feet to a state similar to walking barefoot, so as to produce an upper that fits the contours of the feet, release the feet and bring a barefoot-like sports experience, and provide Exercise your muscles in comfort.

Problems solved by technology

[0003] At present, for knitted shoe uppers, flat film drafts are usually used as the basis for plate-making design, and they are cut with a laser machine after getting off the machine. Because the film itself does not fit the shoe last completely, and the influence of the material on the film is not considered, there is a certain error. After being converted into a horizontal knit, it is deformed again, and the error increases, and most of the film is left-right symmetrical. Plane graphics do not consider the difference between the inner side of the foot, the outer side of the foot, and the physiological surface of the instep, nor do they consider the correspondence between the curved surface and the plane. As a result, the produced upper does not fit the outline of the foot, which limits the free movement of the foot.
