Description

Three-dimensional weft knitted fabric for upper

The present invention relates to a three-dimensional weft knitted fabric for an upper, and more particularly to a fabric which can be used as an upper and has a three-dimensional texture.

Shoes can be generally divided into three parts: the upper, the tongue and the sole. Among them, the upper not only serves as a covering foot, but also avoids the foot injury caused by the friction between the article and the foot, and also has the function of allowing the user to distinguish whether the pair of shoes are owned by themselves and make the shoes more beautiful.

One of the traditional methods of covering the foot and avoiding the damage of the foot and the foot to cause foot injury is to directly thicken the upper. However, this method increases the weight of the shoe and is not conducive to the weight reduction of the shoe. . Another method is to use a foamed material as the upper, but the foaming material has low gas permeability, which is disadvantageous for the foot to be wetted and exhausted. If a fabric having a three-dimensional texture and a breathable property can be used as the upper, the above-mentioned weight increase and the problem of moisture excretion of the foot can be improved.

For the function of letting the user distinguish whether the shoes are all owned by themselves and make the shoes more beautiful, the fabric with three-dimensional texture is used as the upper, which can significantly increase the flexibility of the design of the appearance, further increase the recognition and aesthetics of the shoes. .

The embodiment of the second woven layer is interlaced with a three-dimensional weft knitted fabric; and FIG. 5 is a schematic view showing an embodiment of the three-dimensional weft knitted fabric for the upper in which the outer side of the three-dimensional region is convex outward.

As shown in the embodiment of FIG. 1A, the three-dimensional weft knitted fabric 900 for an upper of the present invention includes a loft layer 100 and a woven layer 300. The fluffy layer 100 consists of a plurality of thicknesses (ie, line density) of 900 denier (long fiber system, fixed length system, Denier (D), D=Y, and the fiber weight per 9000 meters is Y grams, which is Y Danny. The larger the Y value is, the thicker it is. The first wire 110 is composed of the above. The first wire 110 may be various functional fibers and yarns or heterogeneous materials such as plant fibers, animal fibers, rayon fibers, and metal fibers, or may have a yarn appearance or shape such as an insulated wire or an optical fiber. The woven layer 300 includes a first woven layer 310 and a second woven layer 320. The first woven layer 310 and the second woven layer 320 are disposed on opposite sides of the bulk layer 100. The woven layer 300 defines a flat region 400 and a solid region 600 that surrounds the solid region 600. In this embodiment, the first woven layer 310 and the second woven layer 320 have a distance D ₄₀₀ between the flat regions 400 that is less than the distance D ₆₀₀ between the two.

As seen in the embodiment of FIG. 1A, the three-dimensional weft knitted fabric 900 for an upper includes a first woven layer 310, a fluffy layer 100, and a second woven layer 320, as viewed from different angles. The fluffy layer 100 is disposed on one side of the first woven layer 310, and has a plurality of linear densities of more than 900 denier. The first wire 110 is composed. The second woven layer 320 is disposed on the other side of the bulk layer 100 relative to the first woven layer 310. Wherein, the first woven layer 310 and the second woven layer 320 collectively sandwich the fluffy layer 100 so that the portion of the fluffy layer 300 that is surrounded and clamped is flat, and the portion that is not clamped is fluffy.

Since the bulk layer 100 is composed of a plurality of first wires 110 having a linear density of 900 denier or more, the bulk layer 100 has a good bulkiness in the solid region 600. More specifically, the first wire 110 of the bulk layer 100 can be regarded as a support frame disposed in the three-dimensional region 600. Since the linear density thereof is more than 900 denier, that is, it has a thick wire diameter and a large space is occupied. Thereby playing a better fluffy role.

In the embodiment shown in FIG. 1A, the first wire 110 is composed of a multi-layer stack to form the bulk layer 100. In other words, the first wires 110 can be overlapped and staggered on different planes. However, in various embodiments as shown in FIG. 1B, the first wire 110 may constitute the bulk layer 100 in a single layer arrangement. More specifically, the first wire 100 itself has bulkiness, so that when it is in the three-dimensional region 600, since it is not restrained by the first woven layer 310 and the second woven layer 330, its bulkiness can be sufficiently exhibited.

As shown in the embodiment of FIG. 1B, the pitch D _{400 of the} first braid layer 310 and the second braid layer 320 in the flat region 400 is slightly larger than the line thickness of the first wire 110. More specifically, the first wire 110 has bulkiness, and the pitch D _{400 of the} first woven layer 310 and the second woven layer 320 in the flat region 400 is necessarily not less than the line thickness of the first wire 110 in the most compressed state.

In the embodiment shown in FIG. 1A , the first woven layer 310 and the second woven layer 320 are interlaced in the flat region 400 across the fluffy layer 100 , thereby limiting the first woven layer 310 and the second woven layer 320 in the flat region 400 . Pitch. The schematic diagrams of the regions 410, 420, and 430 in the embodiment shown in FIG. 1A are as shown in FIGS. 2A, 2B, and 2C, respectively. Viewed from different angles, as shown in Figure 2D In the illustrated embodiment, the first wire 110 of the bulk layer 100 is a floating yarns disposed between the two layers when the first woven layer 310 and the second woven layer 320 are woven, and the solid region 600 (see FIG. 1A) An area in which the first woven layer 310 and the second woven layer 320 are not woven through the fluffy layer 100.

Further, the three-dimensional weft knitted fabric 900 for an upper of the present invention can produce a partial fluffing effect. As shown in the embodiment of FIG. 3A, the first wire 110 penetrates from one side of the first woven layer 310, and is not interlaced with the first woven layer 310 and the second woven layer 320 (see FIG. 1A) in the solid region 600. That is, the space between the first woven layer 310 and the second woven layer 320 in the range of the solid region 600 is substantially filled, so that the three-dimensional region 600 has a fluffy effect, and then the first woven layer 310 is pierced. Wherein, before the first wire 110 is inserted from one side of the first woven layer 310, the knitting process first performs a "shifting" as shown in FIG. 3B, moving the stitch on the lower knitting needle to the upper knitting needle, and then A wire 110 enters between the upper and lower knitting needles as shown in Fig. 3C, and then the first knitted layer 310 and the second knitted layer 320 are continuously knitted as shown in Fig. 3D. FIG. 3E is a schematic view showing the knitting of the region 440 in the embodiment shown in FIG. 3A.

The first woven layer 310 and the second woven layer 320 can be interwoven in a variety of ways. For example, in the embodiment shown in FIG. 4A, the first yarn 301 is bent by the action sequence of the knitting needle 500 to form a plurality of first coils 331, and the first coils 331 are sleeved with each other to form the first braid layer 310. After the yarn 301 forms the last first coil 331, the flat region 400 (see FIG. 1A) passes through the bulk layer 100, and then sequentially bends to form a plurality of second coils 332, which are nested together to form a second weave. Layer 320. This interlacing method is particularly suitable for the boundary position of the solid region 600 and the flat region 400 when the three-dimensional weft knitted fabric 900 is partially bulky, and the other interlacing manners of the embodiments shown in Figs. 4B to 4D are also the same. In addition, it can be because of design, manufacturing, or use requirements. There are different ways of interlacing.

In another interlacing manner of the embodiment shown in FIG. 4E, after the first yarns 301 are sequentially bent to form m first coils 331, the flat regions 400 (see FIG. 1A) pass through the bulk layer 100 and are bent to form a third coil 333. Thereafter, the flat region 400 (see FIG. 1A) passes through the bulk layer 100, and is bent to form n first coils 331. The second yarns 302 are sequentially bent to form a plurality of second coils 332, m and n first coils 331. The first braid layer 310 is formed in series with each other, and the third coil 333 and the second coil 332 are sleeved with each other to form the second braid layer 320. This interleaving method is particularly suitable for the flat region 400 between the three-dimensional regions 600, and the other interleaving manners of the embodiment shown in FIG. 4F are also the same. The difference between the embodiments shown in FIGS. 4E and 4F is that in the embodiment shown in FIG. 4F, there are no empty pins between m and n first coils 331.

In various embodiments, the first woven layer and the second woven layer are not limited to interlace to limit the spacing therebetween. For example, the first woven layer and/or the second woven layer may comprise a thermoplastic material, the first woven layer and the second woven layer being adjacent to each other in the flattened region, pressed against and adhered to the fluffy layer, and thermoplastically shaped. Further, the first woven layer and the second woven layer which are pressed and adhered to the fluffy layer can be melted and passed through the fluffy layer after being heated, and then adhered to each other after cooling, thereby locking the fluffy layer therebetween.

In the embodiment shown in FIG. 1A, the first woven layer 310 and the second woven layer 320 of the woven layer 300 respectively protrude outwardly from the solid region 600. In other words, the three-dimensional weft knitted fabric 900 has an outwardly convex shape on both sides of the three-dimensional region 600. However, in various embodiments, the three-dimensional weft knitted fabric 900 may be outwardly convex on only one side of the solid region 600 due to design, manufacturing, or use requirements. For example, in the embodiment illustrated in FIG. 5, the first woven layer 310 of the woven layer 300 projects outwardly in the embossed region 600, and the second woven layer 320 remains flat.
