Description

Technical Field

[0001] This invention relates to the field of knitted fabric technology, and in particular to a knitted fabric that conforms to the physiological curve of the heel and its manufacturing method. Background Technology

[0002] The comfort of shoes is usually judged by how well the shoes fit the feet. Conventional knitted fabrics require multiple processes such as cutting and sewing to create the curve at the heel. The process is complex and tedious, takes a long time to produce, and results in a lot of material waste. This solution was developed to address these issues. Summary of the Invention

[0003] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description, claims, and other accompanying drawings.

[0004] To address the shortcomings of existing technologies, this invention provides a knitted fabric that conforms to the physiological curve of the heel. The fabric body includes an upper, collar, tongue, and heel section, all integrally knitted. The heel section has separate outer and inner layers. The fabric is woven from at least one first yarn and one second yarn, which are used for bottom and surface knitting. A pocket-like structure is provided between the outer and inner layers. The heel section also includes an integrally knitted heel with a curved arc. The fabric is knitted using a knitting machine. The outer and inner layers are not connected. The pocket-like structure contains filling material. During knitting, the filling material is placed inside the pocket-like structure, and then sealed by the non-layered knitting of the outer and inner layers. The outer and inner layers are interconnected. Yarn is woven into the pocket-like structure and connected by the yarn.

[0005] Preferably, the curvature of the heel is woven using a shovel stitch method.

[0006] Preferably, the first yarn is a high-elasticity yarn or a low-elasticity yarn.

[0007] Preferably, the second yarn is a high-elasticity yarn or a low-elasticity yarn.

[0008] Preferably, the first yarn and the second yarn are transparent yarns or colored yarns.

[0009] Preferably, the low-elasticity yarn is one or a combination of polyester yarn, nylon yarn, polypropylene yarn and cotton yarn.

[0010] Preferably, the high-elastic yarn includes at least one of polyester, nylon, acrylic and spandex.

[0011] The present invention also provides a method for knitting a fabric that conforms to the physiological curve of the heel, comprising the following steps:

[0012] S1: Select at least two types of yarn for knitting the fabric, where yarns A and B are one type of yarn used for knitting the heel area of ​​the fabric, and yarns C and D are another type of yarn used for knitting the elastic neckline;

[0013] S2: Yarn A is used for the upper weave, yarn B is used for the sole weave, yarns A and B are used for the shoe body, yarns C and D are used for the elastic neckline with eyelets, and the shoe body and elastic neckline are connected by eyelets of yarn A (upper), yarn B (sole), yarn C (upper), and yarn D (sole).

[0014] S3: Use A and B yarns to knit a partial stepped shovel stitch to the left, knitting half of the heel curve;

[0015] S4: Use yarns A and B to knit the full needle surface and bottom edge respectively, filling the blanking stitch positions of S3;

[0016] S5: A and B yarns are used to make a partial stepped shovel stitch to the right to knit the other half of the heel curve, corresponding to the shovel stitch position in S3;

[0017] S6: A and B yarns are used for full needle surface knitting and bottom edge knitting respectively, filling the S5 shovel stitch position, and S3 to S5 form a complete heel arc knitting area;

[0018] S7: Continue weaving the other parts of the shoe body until the weaving is finished.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are:

[0020] 1. This fabric is woven from colored / uncolored yarns and elastic yarns. The upper collar, tongue, and even the physiological curve of the heel are all woven together in one piece. The upper fits the foot perfectly, providing all-round protection and making it very comfortable to wear.

[0021] 2. The heel area of ​​the fabric also adopts a layered weaving process, leaving "pocket-like" structures to facilitate subsequent filling of the heel area, resulting in better shoe coverage after filling.

[0022] 3. Knitted shoe uppers made using this method can omit many processing steps for the heel area, which reduces shoe production time, reduces waste of knitting materials, saves production costs, and allows for more efficient production. Attached Figure Description

[0117] After the fabric is woven, it still needs to undergo high-temperature treatment. For fabrics that do not use hot melt yarn, high-temperature treatment is to allow the fabric to shrink fully under heat to achieve the desired fabric effect. For fabrics that use hot melt yarn, high-temperature treatment is required to melt and bond the hot melt yarn into the fabric to achieve the desired fabric effect.

[0118] The outer layer of the heel described above is a bag-shaped cavity exposed on the outside, while the outer layer of the heel is the bottom layer that fits the foot.

[0119] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
