Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of knitting, in particular to a warp-knitted long-hole type knitted fabric and a knitting process thereof. BACKGROUND

[0002] Holes are an important part of a conventional shoe upper. Common hole types are mainly related to the knitting method. Limited by the traditional knitting method, the appearance of conventional holes has great limitations in shape and height. If a long-hole type is to be formed, a conventional method needs to be used with a needle, but the long-hole type formed by the needle has inconspicuous eyelets. If subsequent cutting of the holes is performed, the production process will be increased, and the production cost will be increased. SUMMARY

[0003] The present application provides a warp-knitted long-hole type knitting process, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present application to solve its technical problems is:

[0005] In a first aspect, the present application provides a warp-knitted long-hole type knitted fabric, which is formed by integrally knitting a plurality of yarns in the warp direction by a knitting device. During knitting, the parallelly arranged yarns are fed into parallelly arranged working needles in the warp direction, and are simultaneously looped.

[0006] In a preferred technical solution, the knitted fabric includes locally knitted adjacent first and second regions, and the warp direction height of the two regions determines the warp direction length dimension of the hole type.

[0007] In a preferred technical solution, the knitted fabric further includes a third region, and the third region controls the weft direction length dimension and shape of the hole type by transfer knitting.

[0008] In a preferred technical solution, the knitted fabric is knitted to form a hole, and the warp and weft direction dimensions of the hole type can be adjusted and changed when the knitting process is set.

[0009] In a preferred technical solution, the position of the hole on the knitted fabric can be adjusted and changed when the knitting process is set.

[0010] In a preferred technical solution, the knitted fabric is knitted to form at least one warp direction long-hole type.

[0011] In a preferred technical solution, the warp direction long-hole type and other hole types or textures can be simultaneously embodied on a knitted fabric by changing the knitting process.

[0012] In a preferred technical solution, the textures include plain weave texture, twill weave texture, satin weave texture, and jacquard texture.

[0013] A preferred technical solution: the weaving method of the longitudinal long-hole type includes local weaving and multi-nozzle side weaving.

[0014] In a second aspect, the present application provides a knitting process for knitting a knitted fabric of a longitudinal long-hole type, the knitting process comprising: S1: selecting one or more yarns for knitting the knitted fabric, the yarns used for base knitting being defined as B yarns, and the yarns used in other knitting areas being defined as A yarns, wherein the A yarns and the B yarns are the same yarn or different yarns;

[0015] S2: using the A yarns to perform four-level knitting and face knitting with needle separation knitting for the first knitting row, and using the B yarns to perform base knitting for the next knitting row;

[0016] S3: continuing to use the A yarns to perform four-level knitting and face knitting with needle separation knitting after S2, and the knitting position is offset by a number of needle positions from the first knitting row;

[0017] S4: moving the loops of the selected knitting columns to the left and right by a number of needle positions respectively to perform loop transfer knitting to control the length and shape of the weft direction of the hole type;

[0018] S5: selecting to repeat the above knitting actions to knit the knitted fabric.

[0019] The knitted fabric is knitted by the knitting process for knitting a longitudinal long-hole type in the second aspect. The knitted fabric has the characteristics that it is knitted in one piece, and the stability of the hole structure and the appearance of the knitted fabric are significantly improved compared to traditional knitting methods. Especially when the long-hole type is arranged on the knitted fabric, the traditional knitting method uses a sleeve needle, the hole formed by knitting is not obvious, the original large hole becomes smaller through the sleeve needle, and some yarns will deviate into the hole, so manual cutting is required later.

[0020] By using the above technical solution, the present application has the following advantages:

[0021] The knitted fabric knitted by the knitting process has strong variability and controllability in appearance style, and the number and area of the finally formed hole type are more diversified and less restricted than traditional mesh knitting.

[0022] The knitted fabric knitted by the knitting process has small restrictions on the appearance style of the long-hole type formed by the fabric, and can be adjusted according to different production needs. Unlike traditional small holes, this type of hole has a strong modeling effect and gives a strong visual impact.

[0023] The knitting process of the present application has a smooth hole edge when knitting the hole, which is not easy to scatter and has strong stability. BRIEF DESCRIPTION OF DRAWINGS
