The invention is further described below with reference to the figures and the specific embodiments.

The embodiment provides an application of knitted fabric in shoes with effect of discolouing for vamp 1 has the characteristics of effect of discolouing, still has characteristics such as the support intensity is strong, the gas permeability is good simultaneously.

As shown in fig. 1, an upper with color-changing effect comprises an upper 1 formed by integrally weaving, wherein the upper 1 comprises a planar area 2, an outwardly convex area 3 and a color-changing area 4 arranged at the joint of the planar area 2 and the convex area 3, the color-changing area 4 comprises a first color area 41 arranged at the light-oriented part of the joint of the planar area 2 and the convex area 3 and a second color area 42 arranged at the backlight part of the joint of the planar area 2 and the convex area 3, the upper 1 presents a first visual effect with a first color matched with the first color area 41 at a first viewing angle, and the upper 1 presents a second visual effect with a second color matched with the second color area 42 at a second viewing angle.

The first viewing angle is different from the second viewing angle, and the first color is different from the second color.

The first visual angle is from the light facing part to the backlight part, namely, from the light facing surface to the backlight surface, the second visual angle is from the backlight part to the light facing part, namely, from the backlight surface to the light facing surface, and the first color is different from the second color, namely, when the vamp is observed at the two visual angles, the vamp can present the visual effect of two different colors.

The plane area 2 is formed by weaving a first yarn and a second yarn together, the protruding area 3 is formed by weaving the first yarn, the second yarn and a third yarn together, the first color area 41 is formed by weaving a first colored yarn, the second color area 42 is formed by weaving a second colored yarn, and the first colored yarn and the second colored yarn have different characteristics.

The first colored yarn and the second colored yarn are provided with one or more of different yarn types, different colors, different textures and different deniers.

The first yarn and the third yarn are both polyester high-elastic yarns, and the second yarn is made of thermoplastic polyester materials such as thermal fuses.

The number of the third yarns is larger than that of the first yarns, and the third yarns are knitted in a hanging manner, so that the effect of the protruding parts is enhanced.

As shown in fig. 2, this embodiment also provides a process for manufacturing the vamp with color-changing effect, which comprises the following steps:

A. weaving: the 1 st and 2 nd knitting lines are a first yarn and a second yarn to make a one-turn cross-over bottom knitting, the 3 rd and 4 th knitting lines are a needle-over knitting in which the 1 st and 2 nd knitting lines are needle-over knitted to the bottom knitting line, the 5 th knitting line is a first yarn and a second yarn cross knitting, the 6 th knitting line is a first colored yarn and a bottom knitting corresponding to the 5 th knitting line, the 7 th knitting line is a needle-over knitting in which the 5 th knitting line is needle-over knitted to the bottom, the 8 th, 9 th, 10 th and 11 th knitting lines are knitting forms in which a convex area on the knitting fabric is made, the 8 th knitting line is a cross knitting of the first yarn and the second yarn, the 9 th and 10 th knitting lines are bottom stitch knitting forms in which the third yarn is surface knitting, the 11 th knitting line is a bottom knitting corresponding to other knitting lines, the 12 th knitting line is a needle-over knitting in which the front knitting line is needle-over knitted to the bottom, the 13 th knitting line is a bottom color yarn cross knitting, and the 14 th knitting line is a second colored knitting line, the 15 th weaving line turns over the needle knitting of the front weaving line to the needle knitting of the bottom to form a half-cycle weaving, the 16 th to 30 th weaving lines have the same weaving actions as the 1 st to 15 th weaving lines, wherein the 21 st weaving line is the return stroke line of the 6 th weaving line, the 29 th weaving line is the return stroke line of the 14 th weaving line, and the 1 st to 30 th weaving lines form a complete cycle weaving;

B. ironing: and (5) ironing the woven vamp by high-temperature steam.

The yarn that A yarn mouth wore is first yarn, the yarn that B yarn mouth wore is the second yarn, the yarn that C yarn mouth wore is first coloured yarn, the yarn that D yarn mouth wore is the third yarn, the yarn that E yarn mouth wore is the second coloured yarn.

After the vamp 1 is knitted, finishing ironing by high-temperature steam is needed, and for the vamp 1 which does not use the thermal fuse, finishing ironing is to ensure that the vamp 1 is heated and fully contracted so as to achieve the proper effect of the vamp 1; for the shoe upper 1 using the thermal fuse, the thermal fuse needs to be melted and bonded inside the shoe upper 1 through ironing, so as to achieve the proper effect of the shoe upper 1.

The knitting mode of first yarn and second yarn is covering yarn or mixed yarn.

This embodiment is through having set up the protruding district 3 that has the convex line and the plane district 2 that has the sunken line, the structure of the height straggle is formed, and the coloured yarn of different characteristics has been woven to light position and position in a poor light in the combination department of protruding district 3 and plane district 2, make vamp 1 demonstrate the visual effect of different colours under the visual angle of difference, the function that vamp 1 has double-colored discoloration visual effect has been given, the aesthetic property of shoes has been increased, consumer's eyeball has been attracted greatly.

The supporting strength of vamp 1 has been guaranteed to protruding district 3 in this embodiment, has played certain protection supporting role, and plane district 2 also makes vamp 1 have good air permeability when having guaranteed the structure of high-low dislocation, and the structure is unique, and the function is abundant.

This embodiment presents double-colored color-changing visual effect through height structure of falling by mistake, and uses the changeable colour yarn to realize changing the function and compare, and the yarn price that this embodiment used is lower, and the price/performance ratio is higher, and environmental protection more is fit for large-scale production moreover.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the present invention, and all equivalent variations and modifications made in the claims of the present invention should be included in the scope of the present invention.
