Description

Technical Field

[0001] The present invention relates to a knitted shoe upper, specifically a knitted shoe upper formed in a tubular and sheet-like integral shape and a knitting process. Background Art

[0002] Traditional shoe uppers are mainly produced in the following ways:

[0003] The first method is to select the corresponding upper fabric and then go through a series of tedious subsequent processes such as typesetting, laser cutting, and sewing, which wastes a lot of scraps. This is inefficient and greatly prolongs the product production cycle, which is time-consuming and labor-intensive.

[0004] The second method is to produce independent sheet uppers through flat knitting. Compared with the first method, this method eliminates the generation of a large amount of scraps and scraps and saves the process of cutting the flat contour of the upper. However, it still requires a lot of post-processing steps, and the product production cycle is still not short and is still time-consuming and labor-intensive. In particular, the tubular parts of the upper are all sewn together instead of being integrally formed.

[0005] The third method is to produce independent open tubular uppers through hosiery knitting machines, which only require a simple and efficient head stitching. This production method has simple and efficient processes, saves labor and greatly shortens the production cycle. However, due to the limitations of the hosiery machine's own functions, it can only produce single-layer or double-layer open tubular uppers. The tubular uppers themselves restrict the subsequent deep processing of the uppers (deep processing includes: printing, embroidery, branding, diamond sticking, local compounding, etc.), which ultimately restricts the application of diversified design elements of this type of uppers, resulting in the current situation of this type of uppers having a single style, insufficient variety, and low grade.

[0006] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. Summary of the invention

[0007] The present invention mainly solves the shortcomings of traditional shoe uppers and traditional production methods, and provides a kind of knitted shoe upper and weaving process that is formed into a tubular and sheet-shaped whole, which has no waste of scraps, simple and efficient process, and the product is suitable for further processing of the shoe upper.

[0008] A knitted shoe upper with integrated tubular and sheet parts, comprising a knitted shoe upper. The knitted shoe upper is composed of an integrally knitted tubular part and a sheet part. The sheet part includes an open end that can be unfolded. Since the tubular part and the sheet part are integrally knitted on the same shoe upper, the tubular part realizes the forming functions of efficient shoe upper, heel, shoe body and other parts, while the sheet part achieves the development of post-processing of the shoe upper (post-processing includes: printing, embroidery, branding, rhinestone application, local lamination, etc.). The integrated forming structure of the two is more convenient and efficient than the traditional structure, expanding the process of the shoe upper, increasing variable elements and diversity. Both the tubular part and the sheet part are weft knitted structures integrally knitted by a weft knitting machine.

[0009] The open end of the sheet part is located at the starting knitting end of the fabric, and the ending end of the fabric is the tubular part. Specifically, the process is as follows: the sheet part is a sheet weft knitted structure, the tubular part is a tubular weft knitted structure, the starting knitting end of the fabric is a sheet weft knitted structure. By the reciprocating operation of a single or multiple paths of the weft knitting machine and the needles participating in knitting at the head and tail are not double-fed or connected by tuck stitches, an open end with one end open and capable of being unfolded is realized, thus forming a sheet weft knitted structure. When knitting reaches the ending end of the fabric of the knitted shoe upper, the tubular weft knitted structure is realized by the unidirectional operation of the weft knitting machine, or by the unidirectional operation of multiple paths or the reciprocating operation of multiple paths of knitting.

[0010] The open end of the sheet part is located at the ending knitting end of the fabric, and the starting end of the fabric is the tubular part. Specifically, the process is as follows: the sheet part is a sheet weft knitted structure, the tubular part is a tubular weft knitted structure, the starting knitting end of the fabric is a tubular weft knitted structure. The tubular weft knitted structure is realized by the unidirectional operation of the weft knitting machine, or by the unidirectional operation of multiple paths or the reciprocating operation of multiple paths of knitting. When knitting reaches the ending end of the fabric of the knitted shoe upper, an open end with one end open and capable of being unfolded is realized by the reciprocating operation of a single or multiple paths of the weft knitting machine and the needles participating in knitting at the head and tail are not double-fed or connected by tuck stitches, thus forming a sheet weft knitted structure.

[0011] Both the starting and ending ends of the fabric are open ends with sheet-like parts, and the tubular part is located between the starting and ending ends of the fabric. Specifically, the process is as follows: the sheet-like part is a sheet-like weft knitting structure, the tubular part is a tubular weft knitting structure, and the starting knitting end of the fabric is a sheet-like weft knitting structure. By the reciprocating operation of a single path or multiple paths of a weft knitting machine, and there is no double eating or connecting with a gathering stitch between the knitting needles participating in the knitting at the head and tail, an open end that can be unfolded is realized, thus forming a sheet-like weft knitting structure. When knitting to the middle part of the knitted shoe upper, it is knitted by the unidirectional operation of the weft knitting machine, and it can also be realized by the unidirectional operation of multiple paths or the reciprocating operation of multiple paths to form a tubular weft knitting structure. When knitting to the ending end of the fabric of the knitted shoe upper, by the reciprocating operation of a single path or multiple paths of a weft knitting machine, and there is no double eating or connecting with a gathering stitch between the knitting needles participating in the knitting at the head and tail, an open end that can be unfolded is realized, thus forming a sheet-like weft knitting structure.

[0012] As a knitting process, the tubular part is a tubular weft knitting structure. The tubular weft knitting structure can be knitted by the unidirectional operation of a weft knitting machine, or can also be knitted by the unidirectional operation of multiple paths or the reciprocating operation of multiple paths. The weft knitting machine can realize the reciprocating operation of 360° of the needle cylinder, and in the reciprocating operation, the arbitrary control of 3 needle positions of single path or multiple paths corresponding to yarn mouths for looping, gathering, and hiding needles is realized to form a tubular weft knitting structure; the sheet-like part is a sheet-like weft knitting structure. By the reciprocating operation of a single path or multiple paths of a weft knitting machine, and there is no double eating or connecting with a gathering stitch between the knitting needles participating in the knitting at the head and tail, an open end that can be unfolded is realized, thus forming a sheet-like weft knitting structure. Regarding the outer contour of the sheet-like weft knitting structure, within the total number of needles of the needle cylinder of the weft knitting machine, the increase and decrease of the number of knitting needles participating in the knitting are controlled to realize the control of the size of the outer contour of the sheet-like weft knitting structure.

[0013] For the tubular weft knitting structure in the present invention, the tubular weft knitting structure produced by the unidirectional operation of multiple paths can realize the knitting applications of single rib, double rib, plain weave, jacquard, plating, gathering, etc., and has a relatively high knitting efficiency; the tubular weft knitting structure produced by the reciprocating operation of multiple paths is composed of more than two corresponding independent sheet-like knitting blocks, which are connected by double eating or gathering stitches, and can realize the knitting applications of single rib, double rib, plain weave, jacquard, plating, gathering, jacquard without dotted line, intarsia without dotted line, heel jacquard, mesh hole, eyelet, etc.

[0014] The sheet-shaped weft knitting structure in the present invention, which is a sheet-shaped weft knitting structure produced by single-pass reciprocating operation, can realize the knitting applications of plain weave, jacquard, tuck, seamless intarsia, heel jacquard, mesh hole, eyelet, etc.; the sheet-shaped weft knitting structure produced by multi-pass reciprocating operation is composed of two or more corresponding independent sheet-shaped knitting blocks connected by heavy feeding or tuck stitch, and can realize the knitting applications of single rib, double rib, plain weave, jacquard, plating, tuck, seamless jacquard, seamless intarsia, heel jacquard, mesh hole, eyelet, etc.

[0015] To ensure the arbitrary combination and integral molding of the tubular weft knitting structure and the sheet-shaped weft knitting structure, the conversion action between the two tissue structures must be in the process of the machine running forward, so as to effectively avoid knitting problems such as dotted lines and entangled threads.

[0016] As can be seen from the above technical solutions, the knitted shoe upper formed by the integral knitting of the tubular part and the sheet-shaped part of the present invention has no waste of corner scraps and directly matches the sole, and the process is simple and efficient. The products are diverse and can be subjected to traditional printing, embroidery, branding, rhinestone application, and local lamination processes. BRIEF DESCRIPTION OF THE DRAWINGS
