Description

A knitted upper using invisible intarsia technology

Technical Field

The invention relates to the technical field of shoe uppers, and in particular to a knitted shoe upper using an invisible intarsia process.

Background Art

In common one-piece knitted uppers, the tongue part with a certain extension is knitted on the low-extensibility upper, usually using intarsia knitting. Intarsia technology refers to the method of forming a colored fabric by knitting two or more pieces of yarns of different colors or types, and then inlaying them longitudinally. When used in upper knitting, it is used to connect the tongue and the instep. However, the intersection of the tongue and the instep formed by knitting with conventional intarsia technology will have obvious marks, and improper handling will affect the appearance of the upper. Therefore, a method is needed to improve the marks of the intarsia intersection to provide a hidden intarsia method and upper fabric.

Summary of the invention

In order to solve the above technical problems, the present invention utilizes the function of a flying knitting machine and the characteristics of yarn to knit a knitted shoe upper using an invisible intarsia process in one step.

A knitted shoe upper using invisible intarsia technology comprises a first knitted tissue and a second knitted tissue embedded and connected between the first knitted tissues, wherein:

The first knitted structure comprises a first surface layer and a first bottom layer, the second knitted structure comprises a second surface layer and a second bottom layer, and the knitting yarn of the second surface layer is the same as that of the first surface layer;

The knitting yarn of the second bottom layer includes a second yarn, which is different from the knitting yarn of the first bottom layer, and an integrally woven intarsia connecting tissue is included between the first bottom layer and the second bottom layer, and the intarsia connecting tissue is a bottom knitting and a bottom tuck knitting woven by the second yarn, wherein the bottom tuck knitting is located at the outer knitting position of the bottom knitting.

Furthermore, the first knitted structure also includes a first connecting layer for connecting the first surface layer and the first bottom layer.

Furthermore, the second knitted structure also includes a second connecting layer for connecting the second surface layer and the second bottom layer.

Furthermore, the first knitted structure is a shoe body, and the second knitted structure is a shoe tongue.

Furthermore, the first knitted tissue is a shoe body, and the second knitted tissue is a functional tissue of the shoe body embedded between the first knitted tissues.

Furthermore, the elasticity of the second yarn is greater than the elasticity of the braided yarn of the first bottom layer, and the ductility of the second bottom layer is greater than that of the first bottom layer.

Furthermore, the second yarn is any one of antibacterial yarn, warm yarn, and cool yarn.

Furthermore, the second yarn is spandex core-spun yarn.

Furthermore, the first surface layer includes full-needle surface knitting and/or one-by-one-needle surface knitting; the second surface layer includes full-needle surface knitting and/or one-by-one-needle surface knitting.

Furthermore, the first bottom layer includes full-stitch bottom knitting; and the second bottom layer includes full-stitch bottom knitting.

Beneficial Effects

Compared with the prior art, the present invention only weaves the intarsia area on the bottom layer of the upper, keeps the weaving material and weaving pattern of the surface layer unchanged, and hides the intarsia intersection position in the tissue pattern of the surface layer. This not only ensures the integrity of the upper appearance, but also ensures the high extensibility or specific functionality of the intarsia area, improves the problem of obvious intarsia intersection marks, and at the same time, the novel creativity will also provide new design ideas and development directions for the design and production of other new uppers.

DETAILED DESCRIPTION

The present invention will be further described below through examples and drawings.

A knitted shoe upper using invisible intarsia technology, as shown in Figures A-C of Figures 1 and 2, includes a first knitted tissue 1 and a second knitted tissue 2 embedded and connected between the first knitted tissue 1, wherein:

The first knitted structure 1 comprises a first surface layer 10 and a first bottom layer 11, and the second knitted structure 2 comprises a second surface layer 20 and a second bottom layer 21, wherein the knitting yarn of the second surface layer 20 is the same as that of the first surface layer 10;

The knitting yarn of the second bottom layer 21 includes a second yarn, which is different from the knitting yarn of the first bottom layer 11. An integrally woven intarsia connecting tissue 22 is included between the first bottom layer 11 and the second bottom layer 21. The intarsia connecting tissue 22 is a bottom weave and a bottom tuck weave woven by the second yarn, wherein the bottom tuck weave is located at the outer weaving position of the bottom weave.

As a preferred mode of this embodiment, the first knitted structure 1 further comprises a first connecting layer for connecting the first surface layer 10 and the first bottom layer 11. This mode can weave a three-layer structure of the first knitted structure 1 with an air layer effect.

As a preferred mode of this embodiment, the second knitted structure 2 further includes a second connecting layer for connecting the second surface layer 20 and the second bottom layer 21. This mode can weave a three-layer structure of the second knitted structure 2 with an air layer effect.

As a preferred embodiment of the present invention, the first knitted tissue 1 is the shoe body, and the second knitted tissue 2 is the shoe tongue. Considering that the shoe tongue is usually woven with yarn with higher elasticity and its physical properties are different from those of the shoe body, the shoe tongue formed by the intarsia tissue in the above manner can maintain its overall appearance consistent and still bring about differences in the shoe tongue performance.

As a preferred mode of this embodiment, the first knitted tissue 1 is a shoe body, and the second knitted tissue 2 is a functional tissue of the shoe body embedded between the first knitted tissue 1.

As a preferred mode of this embodiment, the elasticity of the second yarn is greater than the elasticity of the braided yarn of the first bottom layer 11, and the ductility of the second bottom layer 21 is greater than that of the first bottom layer 11. For example, the braided yarn of the first bottom layer 11 can be a high elastic yarn such as high elastic polyester and high elastic nylon, and the second yarn can be an elastic yarn such as core-spun yarn and elastic composite yarn. The elasticity of the second yarn is greater than that of the braided yarn of the first bottom layer 11, so that the second bottom layer 21 can be given better ductility. This setting can be applied to the tongue and the body of the shoe. Considering that the elasticity of the tongue is generally greater than that of the body of the shoe, the tongue is the above-mentioned second knitted tissue 2, and the body of the shoe is the first knitted tissue 1. The bottom layer of the tongue adopts the above-mentioned elastic yarn, and the overall elasticity of the tongue woven by it is greater than that of the body of the shoe, and the surface layer is still woven as a whole, showing the effect of invisible intarsia. In addition, it can also be applied to other positions of the upper, such as the toe and the upper, or the heel and the upper, or the middle of the upper is embedded with a higher elastic second knitted tissue 2 to obtain a local high elastic tissue, and the consistency of the appearance of the upper can still be ensured.

As a preferred mode of this embodiment, the second yarn is any one of antibacterial yarn, warm yarn, and cool yarn. The antibacterial yarn can be any braided antibacterial yarn material in the prior art, such as antibacterial polyester, antibacterial nylon, graphene yarn, etc. The warm yarn can be hollow polyester, far-infrared yarn, etc. The cool yarn can be cool jade yarn, ice oxygen bar yarn, etc. The yarn that can bring coolness in the prior art, in addition to this, the second yarn can also be a functional yarn such as thermostatic viscose, and the second yarn of the above functional class can give the second bottom layer 21 the above functionality. This setting can be applied to the tongue and the body of the shoe, wherein the tongue is the second knitted tissue 2, and the bottom layer of the tongue is woven by the above functional yarn. In addition, it can also be applied to other positions of the upper, such as the toe and the upper, or the heel and the upper, or the functional second knitted tissue 2 is embedded in the middle of the upper to obtain a local functional tissue, and the consistency of the appearance of the upper can still be ensured.

In this embodiment, a first knitting tissue 1 may include one or more second knitting tissues 2 with similar or different properties. For example, a first knitting tissue 1 may include two or more second knitting tissues 2 with higher elasticity, or two or more functional second knitting tissues 2, or both of the above situations.

As a preferred mode of this embodiment, the second yarn is spandex core-spun yarn.

As a preferred mode of the present embodiment, the first surface layer 10 includes full-needle surface knitting and/or alternate-needle surface knitting; the second surface layer 20 includes full-needle surface knitting and/or alternate-needle surface knitting. The surface layer adopts alternate-needle knitting to enrich the knitting structure type of the upper, which can bring breathability or pattern effect to the surface layer, and the full-needle knitting can improve the overall structure density and stiffness of the upper.

As a preferred mode of this embodiment, the first bottom layer 11 includes full-stitch bottom knitting, and the second bottom layer 21 includes full-stitch bottom knitting. Full-stitch bottom knitting can ensure the density of the bottom layer and the stiffness of the entire upper.
