Detailed Description

The invention will be further explained below with reference to examples and figures.

Example 1

As shown in fig. 1 and 2, a three-dimensional multi-dimensional visual weft knitted fabric comprises a surface layer 1 and a bottom layer 2, wherein the surface layer 1 comprises a plurality of first knitted zones 10 and second knitted zones 11 which are circularly arranged at intervals along a knitting line, the height of the first knitted zone 10 is greater than that of the second knitted zone 11, so that a three-dimensional effect with concave-convex grains is formed, the second knitted zone 11 at least comprises first knitted grains 110 and second knitted grains 111, the yarn colors of the first knitted grains 110 are different, and the bottom layer 2 is a random knitted structure.

In this embodiment, the first knitting region 10 and the second knitting region 11 are arranged at intervals along the knitting line cycle, and therefore the first knitting texture 110 and the second knitting texture 111 in this embodiment refer to the knitting line. Of course, first knit region 10 and second knit region 11 may also be spaced apart cyclically along the knit row, and first knit texture 110 and second knit texture 111 are referred to as knit rows.

The first weaving grain 110 and the second weaving grain 111 have different yarn colors, specifically, the first weaving grain and the second weaving grain are woven by two yarns with different colors, and each weaving grain completely displays the color of the weaving yarn; in addition, the color difference can be that the first weaving grain and the second weaving grain are woven by adopting two yarns with different colors in a jacquard manner, for example, sesame point jacquard is adopted, each weaving grain part displays the color of the weaving yarn, and the other parts of the weaving grains can have the same color, namely two paths of weaving with different colors can be adopted; in addition, the color difference may also be that the first knitting grain and the second knitting grain adopt the same color yarn for jacquard knitting, for example, sesame dot jacquard knitting, but the color of the yarn is different from that of ground color yarn, for example, the ground yarn is black, and the jacquard yarn adopted by the first knitting grain and the second knitting grain is red, so that each knitting grain at least includes two colors, but the color arrangement of the first knitting grain 110 and the second knitting grain 111 is different or the length of the red yarn displayed by the first knitting grain and the second knitting grain is different.

Since the height of the first knitting area 10 is greater than that of the second knitting area 11, and the two knitting areas are circularly arranged, the first knitting texture 110 and the second knitting texture 111 can be seen from the left side and the right side of fig. 1, and the colors of at least two paths of knitting yarns of the second knitting area 11 are different, so that the colors of the surfaces seen from two viewing angles are different, thereby forming the visual effect with different angle color changes. The greater the difference in color between the two knitting patterns of the first knitting area 10 and the second knitting area 11, the more distinct this difference in color is visually. In order to ensure better visual effect, the number of the knitting lines of the first knitting area 10 is the same as or similar to that of the second knitting area 11, that is, the width of the knitting lines is similar to that of the first knitting area 10, and the height of the first knitting area 10 is about 1.5-2 times of that of the second knitting area 11, so that better effect can be achieved.

Example 2

In the present invention, a third knitting grain 112 may be further included between the first knitting grain 110 and the second knitting grain 111 of the second knitting region 11, as shown in fig. 3, and the height of the third knitting grain 112 is the same as the height of the first knitting grain 110 and the height of the second knitting grain 111, or as shown in fig. 4, the height of the third knitting grain 112 may be greater than the height of the first knitting grain 110 and the height of the second knitting grain 111. Increase the third line, then can effectively increase the width of second weaving district 11, the effect of third weaving line can embody two aspects:

the first aspect is that the color of the knitting yarn of the third knitting vein 112 is the same as the color of the yarn of the first knitting vein 110 or the second knitting vein 111, it may increase the width of the first knitting vein 110 or the second knitting vein 111; the second aspect is that the color of the knitting yarn of the third knitting texture 112 is different from the color of the yarn of the first knitting texture 110 or the second knitting texture 111, so that it is possible to increase the width of the second knitting region 11 without changing the colored regions of the second knitting region 11, i.e. the first knitting texture 110 and the second knitting texture 111, which has the following effects: on one hand, for example, as shown in fig. 3, the three knitting lines have the same height, and the color of the third knitting line 112 is different from the color of the first knitting area 10, when the third knitting line is inclined at a certain angle on the left side or the right side, the colors of the first knitting area 10 and the first knitting line 110 or the second knitting line 111 and the third knitting line 112 can be seen, so that the included angle between the sight line and the horizontal plane is reduced, only the color of the first knitting area 10, the color of the first knitting line 110 or the color of the second knitting line 111 can be seen, which increases the variety of the colors changing along with the visual sense; on the other hand, as shown in fig. 4, the height of the third woven texture 112 is greater than that of the first woven texture 110 and the second woven texture 111, when the third woven texture 112 is consistent with the yarn color of the first woven region 10, and the left side or the right side is inclined at a certain angle, the colors of the first woven region 10 and the first woven texture 110 or the colors of the second woven texture 111 and the third woven texture 112 can be seen, so that the included angle between the line of sight and the horizontal plane is reduced, and due to the shielding of the third texture, the third woven texture can only see the colors of the first woven region 10 and the third woven texture 112, that is, the yarns of the first woven texture 110 and the second woven texture 111 can also be hidden along with the change of the viewing angle.

In this embodiment, the second knitting area 11 may further include a fourth knitting texture, a fifth knitting texture, and the like between the first knitting texture 110 and the second knitting texture 111. The principle and effect of which can be designed with reference to the third weaving pattern 112 described above.

Example 3

The present invention may also be a multilayer structure which may include two of the following:

the first is that only the first weaving region 10 is of a multi-layer structure, as shown in fig. 5, a first interlayer 100 is further included between the first weaving region 10 and the bottom layer 2, which can effectively increase the height of the first weaving region 10 and can obtain a better three-dimensional effect of concave-convex patterns.

The second is that an intermediate layer 3 is arranged between the surface layer 1 and the bottom layer 2, as shown in fig. 6, namely, the intermediate layer 3 is arranged between the first weaving area 10 and the bottom layer 2 and between the second weaving area 11 and the bottom layer 2, which can effectively increase the section height of the whole weft-knitted fabric, and can provide better heat retention property and the like.

In the above embodiment, the knitting lines of the first knitting area 10 and the second knitting area 11 may be arranged in a linear interval cycle, or in a wavy or zigzag interval cycle.

The three-dimensional knitted fabric of the embodiment is knitted by a weft circular knitting machine, and the manufacturing method includes but is not limited to the following two methods:

the first is that according to the difference of the heat shrinkability of the knitting yarns of the first knitting area 10, the second knitting area 11 and the bottom layer 2, namely the heat shrinkability of the knitting yarns of the first knitting area 10 is smaller than that of the knitting yarns of the second knitting area 11 and the bottom layer 2, when the fabric is knitted and heat-set, the yarns of the second knitting area 11 and the bottom layer 2 shrink synchronously at high temperature, and the shrinking length is larger than that of the first knitting area 10, the first knitting area 10 bulges to form bulges, and the second knitting area 11 forms a concave layer, so that concave-convex lines are formed.

In the above manufacturing method, the knitting yarns of the first knitting area 10 may be low-stretch polyester yarns or transparent polyester monofilaments, the knitting yarns of the second knitting area 11 and the bottom layer 2 may be high-stretch polyester yarns, and the high-stretch polyester yarns may be high-stretch spandex covered yarns or double-covered polyester yarns; in addition, the knitting yarn can be nylon yarn with thermal shrinkage difference, and the like. The greater the difference in thermal shrinkage between the first knitted zone 10 and the second knitted zone 11 and the knitted yarns of the bottom layer 2, the more pronounced the effect of bulging thereof.

The second method is that according to the difference of knitting density of the first knitting area 10, the second knitting area 11 and the bottom layer 2, the method is applicable when the first knitting area 10 and the second knitting area 11 are circularly arranged at intervals along the knitting rows, on the premise, the knitting density of the first knitting area 10 is larger than the knitting density of the second knitting area 11 and the bottom layer 2, after the heat setting is carried out after the knitting, the knitting layer with smaller density shrinks more, the knitting layer with larger density shrinks less, and concave-convex grains are formed in sequence.

The above embodiments only show some types of yarns commonly used, and other knitting materials such as chemical fibers, animal fibers, plant fibers, regenerated fibers, composite fibers, etc. which can be knitted can be used as the knitting yarns of the present invention.

As another aspect of the present invention, the present invention further provides a shoe upper, at least a portion of which is made of the three-dimensional multi-dimensional visual weft-knitted fabric, which can be applied to at least one portion of an upper, a toe cap or a heel of a shoe, or the whole shoe upper, and the three-dimensional multi-dimensional visual weft-knitted fabric is applied to the shoe upper, when the shoe upper is applied to a shoe, the angle of the shoe upper is continuously changed along with the bending of the sole during walking, and the shoe upper has different color effects.
