Description

Technical Field

[0001] This utility model discloses a shoe material technology, and in particular relates to a three-dimensional warp-knitted shoe upper. Background Technology

[0002] The shoe upper can be made of knitted fabric. Knitted fabric can be woven into various personalized and complex patterns using a circular knitting machine or a computerized flat knitting machine. The patterns can be changed quickly and the fabric quality is good.

[0003] Shoes are becoming increasingly demanding in terms of aesthetics, with greater emphasis placed on the patterns, colors, and other effects of the fabric.

[0004] Consumers prefer shoe uppers with textures that have a strong three-dimensional visual appeal, while some traditional shoe uppers lack these aesthetic decorative effects. Utility Model Content

[0005] The purpose of this invention is to provide a three-dimensional warp-knitted shoe upper to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional warp-knitted shoe upper, comprising an upper body, wherein the upper body comprises a bottom layer and a top layer;

[0007] The bottom layer is woven with ground combs GB1 and GB2, both using a one-through-three-hole yarn threading method. The yarn padding numbers for ground comb GB1 are 1-0 / 2-3 / 1-0 / 4-5 / 3-2 / 4-5 / / , and the yarn padding numbers for ground comb GB2 are 4-5 / 3-2 / 4-5 / 1-0 / 2-3 / 1-0 / / .

[0008] The surface layer uses Jacquard combs JK1.1 and JK1.2, which are interwoven with the ground fabric in a one-through-one-open yarn pattern. The padding yarn number of Jacquard comb JK1.1 is 0-2 / 4-2 / / , and the padding yarn number of Jacquard comb JK1.2 is 0-2 / 4-2 / / .

[0009] Preferably, the surface layer is knitted using a single-needle Jacquard warp knitting machine with a gauge of 24 needles, and the latch needles of the single-needle Jacquard warp knitting machine are installed alternately to form 12 evenly distributed latch needles.

[0010] Preferably, the single-needle sheet jacquard warp knitting machine uses one jacquard comb and two ground combs to pull their respective warp threads, and two guide needles to knit jacquard yarns corresponding to one latch needle.

[0011] Preferably, both the ground combs GB1 and GB2 are made of 280D / 72F semi-dull nylon fully drawn yarn, and the warp feed is 2320mm / 480 rows and 3020mm / 480 rows, respectively.

[0012] Preferably, both the Jacquard combs JK1.1 and JK1.2 are made of 200D / 96F fully dull polyester low-elasticity yarn, and the warp feed is 2900mm / 480 rows.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By rationally configuring the yarn feeding method using the three-needle yarn feeding technique, the original Jacquard three-needle weaving technique is changed. The original 24-needle yarn is halved to 12-needle yarn, and the original one guide needle corresponds to one tongue needle to two guide needles corresponding to one tongue needle. As a result, the Jacquard yarn entering each tongue needle can become a thicker yarn, thus creating a three-dimensional shoe upper with a special appearance effect of uneven, sparse, and irregular surface.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0021] A three-dimensional warp-knitted shoe upper, such as Figure 1 and Figure 2As shown, the shoe includes an upper, which comprises a bottom layer and a top layer. The bottom layer is woven with both GB1 and GB2 ground combs using a one-through-three-hole yarn threading method. The yarn number for GB1 ground comb is 1-0 / 2-3 / 1-0 / 4-5 / 3-2 / 4-5 / / , and the yarn number for GB2 ground comb is 4-5 / 3-2 / 4-5 / 1-0 / 2-3 / 1-0 / / . Both GB1 and GB2 ground combs use 280D / 72F semi-dull nylon fully drawn yarn, with warp feed rates of 2320mm / 480 rows and 3020mm / 480 rows, respectively.

[0022] like Figure 3 The diagram shows a three-needle knitting pattern. The surface layer uses Jacquard guide bars JK1.1 and JK1.2, which are interwoven with the ground fabric in a one-through-one-open pattern. The padding yarn number for Jacquard guide bar JK1.1 is 0-2 / 4-2 / / , and the padding yarn number for Jacquard guide bar JK1.2 is 0-2 / 4-2 / / . Both Jacquard guide bars JK1.1 and JK1.2 use 200D / 96F fully dull polyester low-elasticity yarn, and the warp feed is 2900mm / 480 rows. The fabric is knitted on a single-needle bed sheet Jacquard warp knitting machine with 4 guide bars. The ground guide bars GB1 and GB2 are knitted into a relatively stable figure-eight shape, and the diameter of the warp yarns pulled by the Jacquard guide bars and the ground guide bars is larger than the diameter of the general warp yarns.

[0023] The surface layer is knitted using a 24-needle single-needle Jacquard warp knitting machine. The latches of this machine are installed alternately, resulting in 12 evenly distributed latches. One Jacquard guide bar and two ground guide bars on the machine guide the warp yarns, and two guide needles correspond to one latch needle for knitting the Jacquard yarn. The number of latches on the single-needle Jacquard warp knitting machine is halved, while the guide needles on each guide bar remain unchanged. Figure 4 and Figure 5 The images shown are comparisons of the original 24-needle yarn track and the 12-needle yarn track after halving. By changing from one guide needle to one latch needle to two guide needles to one latch needle, the Jacquard yarn entering each latch needle can become thicker yarn. The basic Jacquard padding yarn number changes from 0-1 / 2-1 / / to 0-2 / 4-2 / / , resulting in a special appearance effect of uneven, sparse, and irregular surface on the woven shoe upper.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
