As consumers' demand for functional fabrics is getting higher and higher, the additional functions of fabrics are also increasing. In addition to antibacterial, moisture absorption, and warmth retention, additional functions, and even the design sense of fabrics are also required. Therefore, the present invention provides a color-changing fabric, the surface layer and the inner layer of which have different colors respectively. , when looking down on the surface of the fabric from the front, another color or even a pattern will appear, which improves the visual variability of the fabric.

Referring to FIG. 1 and FIG. 2 , they are the front and side development schematic diagrams of an embodiment of the color-changing fabric of the present invention, respectively. The color-changing fabric 100 is mainly woven by two different yarns 200 and 300 . More specifically, the two yarns 200 , 300 have different colors, elasticity and thickness respectively, and the two yarns 200 , 300 form the surface yarn layer and the inner yarn layer respectively, thereby forming the color-changing fabric 100 . For the sake of illustration, in the following embodiments, the surface layer yarn 200 is referred to as the surface layer yarn 200 in FIG. 1 which is closer to the front of the drawing (closer to the left of the drawing in FIG. 2, which is closer to the right side of the drawing) is the inner layer yarn 300, which will be described first.

In the color-changing fabric 100, the surface layer yarn 200 is woven to form a plurality of surface layer loops (loop) 210 connected in series. The surface layer yarn loops 210 are connected in series to form a plane surface layer yarn layer by interlocking each other. Each surface yarn loop 210 includes a needle loop 212, two loop posts 214 and a sinker loop 216, wherein the loop column 214 is the part where the upper and lower rows of surface loops 210 are nested, and the needle loops 212 and The sinker arc 216 connects the upper and lower sides of the coil post 214 respectively. That is, the loop posts 214 of the upper row of surface loops 210 are caught by the stitch loops 212 of the lower row of surface loops 210 , and the sinker loops 216 connect the laterally adjacent loop columns 214 . In this embodiment, the surface loops 210 are connected in series in the form of front loops, that is, viewed from the front side of the figure, the loop posts 214 cover the needle loops 212 .

The inner yarn loops 310 are also connected in series to form the inner yarn layer, and each inner yarn loop 310 includes a knitting loop 312, two loop posts 314, and a sinker loop 316 or a needle-moving sinker loop. 318. The inner yarn loops 310 are generally arranged adjacent to each other in the transverse direction, and interlocked with each other in the longitudinal direction so that the inner yarn loops 310 are connected in series to form a plane inner yarn layer. The differences between the weaving methods of the inner layer and the outer layer are: (1) the inner layer yarn loops 310 are connected in series in the form of reverse loops, that is, viewed from the front side of the drawing, the knitting arcs 312 cover the ring posts 314 and (2) the sinker arc 316 of at least a part of the inner layer yarn 300 will turn towards the surface layer yarn layer to form a needle-moving sinker arc 318, and the knitting path of the loop column 214 with the surface layer yarn loop 210 is socketed together. 214 to connect the surface layer yarn layer and the inner layer yarn layer, and then the cloth surface of the surface layer yarn 200 and the cloth surface of the inner layer yarn 300 can be combined without using additional connecting yarns.

Regarding the above-mentioned difference (1), in more detail, the surface layer yarn layer woven by the surface layer yarn 200 and the surface layer yarn layer woven by the inner layer yarn 300 are correspondingly configured one after the other. The knitting loops 212 of the surface loops 210 of the surface layer and the knitting loops 312 of the inner loops 310 of the inner layer are both located on the adjacent inner side of the yarn layer, and the two are arranged correspondingly.

Regarding the difference (2) above, in more detail, the arrangement of the inner loops 310 of the inner yarn 300 in the transverse direction is the same as the arrangement of the outer loops 210 of the outer yarn 200 in the transverse direction, but they are woven in the longitudinal direction. At the same time, the loop length (looplength) of the sinker arc 316 of at least a part of the inner layer yarn ring 310 will be extended to form a needle-moving sinker arc 318 and turn to the loop post 214 of the surface layer yarn ring 210 to socket with it, so as to combine the surface layer yarn layer and the inner layer. Layers of yarn. In this embodiment, all the sinker loops 316 of the inner loops 310 are used as the sinker loops 318 for moving the needle.

When the needle-moving sinker arc 318 of the inner layer yarn loop 310 is sleeved on the coil post 214 of the surface layer yarn loop 210, it is carried out in a predetermined winding manner. For example, in this embodiment, the inner layer yarn 300 passes through the lower left side of the sinker arc 216 of the surface layer yarn ring 210 to the outer layer, and then goes back up to the left side of the sinker arc 216 and passes through the coil post 214 to return to the outer layer. inner layer, and then the inner layer yarn 300 is drawn horizontally to the right side of the coil post 214 by the inner layer. Then, the inner layer yarn 300 passes out to the outer layer from the right side of the coil post 214, and then the inner layer yarn 300 turns downwards and wraps around the sinker arc 216 and passes back the inner layer from the middle of the ring post 214, and returns to the inner layer located in the inner layer. Layer yarn ring 310.

Since the cloth surface formed by the surface layer yarn 200 and the cloth surface formed by the inner layer yarn 300 are combined together by the inner layer yarn 300, there is no need to use another additional link as in the traditional process. The yarn connects the surface yarn layer and the inner layer yarn layer. More specifically, in traditional double-knit fabrics, an additional binding yarn is used, that is, another yarn other than the top layer of yarn connects the two layers with the inner layer of yarn. The loop diameter of the linking yarn will affect the properties of the double-knitted fabric. For example, if the loop diameter of the linking yarn is too long (or is elongated over time), it will cause the shape of the double-knitted fabric. If the shape is too loose, and if the ring diameter of the linking yarn is too short, the elastic extension of the cloth body will be insufficient, and the wearer will feel uncomfortable when making large movements. In contrast, since the inner layer yarn 300 is directly used to connect the surface layer yarn layer and the inner layer layer yarn layer in the present invention, the color-changing fabric 100 can have better integrity and is less likely to be loose or have insufficient elasticity. question.

In this embodiment, the surface yarn 200 is a dark yarn, and the inner yarn 300 is a light-colored yarn with a lighter color than the surface yarn 200, and the extensibility of the surface yarn 200 is similar to that of the thread. The diameters are larger than the extensibility and wire diameter of the inner layer yarn 300. Therefore, when the color-changing fabric 100 is produced in a natural state, it will naturally retract due to the elasticity of the surface yarn 200 and the inner yarn 300 , so that the surface loop 210 and the inner loop 310 gather together. Of course, in other embodiments, the colors of the surface yarn 200 and the inner yarn 300 can also be selected according to different design requirements. For example, the inner yarn 300 can be a dark yarn, and the surface yarn 200 It can be a shallow yarn, etc., as long as there is a certain color contrast between the surface yarn 200 and the inner yarn 300 .

Please refer to FIG. 3 and FIG. 4 , which respectively depict a schematic plan view of the fabric surface before and after stretching of an embodiment of the surface yarn layer of the color-changing fabric of the present invention. Please refer to FIG. 3 first. At this time, since the surface yarn 200 has better extensibility and a thicker wire diameter, the gathered surface yarn loops 210 will produce a fluffy visual effect and provide better shelter. Force, the part of the inner yarn (not shown in the figure) wound around the surface yarn loop 210 of the surface layer will be covered by the gathered surface yarn loop 210, and the front side of the color-changing fabric will show the surface yarn 200 color.

When the color-changing fabric is subjected to stress and deforms, as shown in Figure 4, the surface yarn 200 and the inner yarn (not shown in the figure) will also deform and extend, because the ductility of the surface yarn 200 is relatively low. The extensibility of the layer yarn is good, therefore, the surface layer yarn layer composed of the surface layer yarn ring 210 with better extensibility also has a better elongation ratio. When the color-changing fabric is pulled, the surface layer yarn 200 will change from a fluffy shape to a slender shape due to pulling, so that the surface layer yarn ring 210 is pulled apart to form a gap 215 . This gap 215 provides a spatial range for revealing the color of the inner layer yarn, and can be regarded as allowing the inner layer yarn to emerge from the surface layer when the color-changing fabric is pulled, so that part of the surface of the color-changing fabric can present the color of the inner layer yarn . In addition, because the needle-moving sinker loops of part of the inner layer yarn are sleeved on the corresponding surface layer yarn ring 210, therefore, the inner layer yarn sleeved on the surface layer yarn ring 210 will not be displaced due to external force pulling, and will stay at the The originally corresponding stitch position can emerge in the gap 215 when the surface yarn loop 210 is pulled apart.

Returning to FIG. 1 , the surface yarn 200 may be a composite yarn to provide better extensibility. For example, the surface layer yarn 200 is a composite yarn formed by blending a base yarn (such as PET) and an elastic yarn (spandex), and the inner layer yarn 300 is a PET yarn, so that the surface layer yarn layer is compared with the inner layer yarn. Layered yarn layers have better elasticity. More specifically, the stretch ratio of the surface yarn layer is about 1.1 to 4 times that of the inner yarn layer, and the elastic relationship between the surface yarn layer and the inner yarn layer is preferably such that the stretch ratio of the surface yarn layer is inside 1.1 to 2 times of the elongation ratio of the layer yarn layer, the yarn length of the corresponding inner layer yarn 200 is no more than 1.5 times of the length of the surface layer yarn 300 (with a single surface layer yarn loop 210 and a needle-moving sinking arc 318 for comparison with a single inner loop 310). By selecting the surface layer yarn 200 with a higher elongation ratio, the effect that the surface layer yarn layer can completely cover the inner layer yarn layer can be achieved when no external force is pulled. In some embodiments, the proportion by weight of the elastic yarn in the surface yarn 200 is 0.5% to 35%. In some embodiments, the proportion by weight of the elastic yarn in the surface yarn 200 is preferably 2% to 30%. %, more preferably 2% to 20%.

In addition, in this embodiment, the surface yarn 200 has a fiber size with a larger diameter than the inner yarn 300. Since the color-changing fabric 100 is formed by continuous connection of the surface yarn rings 210, 310, the surface yarn of the surface There is a ring gap between the rings 210. If the ring gap is too large, the color or texture pattern of the inner layer will be exposed on the surface, so the fiber size with a thicker diameter is used as the surface yarn 200 to fill the ring gap. , increase the barrier effect of the surface texture, and solve the problem of color leakage (grindthrough) that is easy to occur on the surface of traditional double-sided knitted fabrics.

To sum up, by properly selecting the color, extensibility, wire diameter, etc. of the surface yarn 200 and the inner yarn 300, and then cooperating with the weaving method mentioned in this embodiment, the color-changing fabric 100 can be made in the future. When subjected to an external force, it presents one color, and when subjected to external force stretching, it presents another color or even a textured pattern. For an example of changing the pattern of the color-changing fabric 100 , please refer to the illustrations in FIGS. 5 to 8 .

Referring to FIG. 5 and FIG. 6 , they are respectively the front and side development schematic views of another embodiment of the color-changing fabric of the present invention. The difference between this embodiment and the previous embodiment is that not every sinker loop 316 of the inner yarn loop 310 in this embodiment is socketed on the surface yarn loop 210 as the needle-moving sinker loop 318, in other words , the inner layer yarn ring 310 of the inner layer can be connected with the surface layer yarn ring 210 of the surface layer in the form of jump stitches, for example, every two rows (longitudinal) just have the inner layer yarn ring 310 of a row of the inner layer not to be connected with the surface layer yarn ring 210 of the surface layer. The rings 210 are connected, and the connection method of the inner layer yarn ring 310 of the inner layer and the surface layer yarn ring 210 of the outer layer has been described in detail above, and will not be repeated here.

The color-changing fabric 100 made by this weaving method will also cover the inner layer yarn 300 due to the good ductility and thicker wire diameter of the surface layer yarn 200 itself without external force. , and present the color of the surface layer yarn 200 itself, as shown in FIG. 7 .

However, when the color-changing fabric 100 is stretched by an external force, the part covered by the inner layer yarn 300 will appear colored, while the part not covered by the inner layer yarn 300 still shows the inherent color of the surface layer yarn 200. The color of , therefore, will form a stripe-like pattern, as shown in Figure 8.

Through the above principles, the designer can elastically adjust the position and ratio of the inner layer yarn 300 over the outer layer yarn 200 according to different requirements, so as to change the color and pattern of the color-changing fabric 100 after being stretched by external force. It should be noted that the designer can choose the color of the surface layer and the inner layer according to actual needs, as long as there is a certain color contrast between the two.

Referring to FIG. 9 , it is a schematic top view of another embodiment of the color-changing fabric of the present invention after stretching. This embodiment is a variation and extension type based on the weaving method in FIG. 5 . For example, if the inner yarn loops are connected to the surface yarn loops in the form of horizontal jump stitches, and each row is extended backward by one stitch in the longitudinal direction, the formed color-changing fabric 100 will be stretched to obtain different colors. The twill pattern formed by the surface layer yarn 200 and the inner layer yarn 300.

The color-changing fabric provided by the present invention provides good covering power when no external force is applied, so that the front side presents the color of the surface layer yarn without revealing the color of the inner layer yarn, and when stretched by an external force, at least part of the area The color of the inner yarn will be revealed. The color-changing fabric has different colors and patterns before and after stress, so that the fabric can provide more visual changes. In addition, since the surface ring and the inner ring are connected through the inner yarn, there is no need to use another connecting yarn for connection, so the color-changing fabric can have better elasticity and extensibility. In addition, by properly arranging the positions and proportions of the inner yarn loops over the surface yarn loops, the pattern presented when the force is applied can be adjusted.

Although the present invention has been disclosed above with the embodiments, it is not intended to limit the present invention. Any skilled person can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection should be based on the scope defined by the appended claims.
