Abstract
Description
Technical Field
[0001] The present invention relates to a double-sided pre-dyed knitted fabric.
Background Art
[0002] Patent Document 1 discloses an invention of knitting a pre-dyed knitted fabric with a circular knitting machine. It can be understood from this patent that the front loops of the conventional pre-dyed knitted fabric are knitted by both the surface yarn and the ground yarn, and color change is realized by changing the relative positions of the surface yarn and the ground yarn to change the form of the front loops. However, although the conventional method can achieve color change, when observing the front loops, a color different from the presented color can be seen just by changing the relative positions of the surface yarn and the ground yarn (the surface yarn is the presented color, and the ground yarn is a color different from the presented color). Therefore, the presented color of the front loops is not pure, and when observing the entire pre-dyed knitted fabric, there is a problem that the pattern composed of a plurality of front loops looks blurred.

[0004] The main object of the present invention is to solve the problem that the presented color of the front loops of the conventional double-sided pre-dyed knitted fabric is affected by a color yarn different from the presented color yarn included in the loops.
Means for Solving the Problems
[0005] To achieve the above objective, the present invention provides a double-sided yarn-dyed knitted fabric comprising a plurality of front loops and a plurality of back loops. The double-sided yarn-dyed knitted fabric is knitted with at least two colored yarns, each of the front loops is knitted with one of the at least two colored yarns, and each of the back loops is knitted simultaneously with the at least two colored yarns, so that the front of the double-sided yarn-dyed knitted fabric is varied by the at least two colored yarns.
[0006] In one embodiment, the colors of the at least two colored threads are different.
[0007] Furthermore, the present invention provides a double-sided yarn-dyed knitted fabric different from those described above, the double-sided yarn-dyed knitted fabric comprising a plurality of front loops and a plurality of back loops. The double-sided yarn-dyed knitted fabric is knitted with a plurality of colored yarns, these colored yarns can be divided into at least two yarn groups, one of the at least two yarn groups comprising two of these colored yarns, and the other of the at least two yarn groups comprising at least one of these colored yarns, each of these front loops is formed by one of the colored yarns included in one of the at least two yarn groups, and each of these back loops is knitted with all the colored yarns included in one of the at least two yarn groups, and the front of the double-sided yarn-dyed knitted fabric is varied by these colored yarns.
[0008] In one embodiment, one of the two adjacent loops on the back surface is knitted with one of the at least two yarn groups, and the other of the two adjacent loops on the back surface is knitted with the other of the at least two yarn groups.
[0009] In one embodiment, one of two adjacent loops in these front loops is knitted with one of two colored yarns included in one of the at least two yarn groups, and the other of two adjacent loops in these front loops is knitted with one of the colored yarns included in one of the at least two yarn groups.

[Modes for carrying out the invention]
[0015] The details of the present invention will be described below with reference to the drawings. Referring to Figures 1 and 2, the present invention provides a double-sided yarn-dyed knitted fabric 20, which is knitted on a double-sided circular knitting machine 60, and which comprises a plurality of front loops 21 and a plurality of back loops 22. In one embodiment, the double-sided yarn-dyed knitted fabric 20 is knitted with at least two colored yarns 30, 31, each of these front loops 21 of the double-sided yarn-dyed knitted fabric 20 is knitted with one of the at least two colored yarns 30, 31, each of these back loops 22 of the double-sided yarn-dyed knitted fabric 20 is knitted simultaneously with at least two colored yarns 30, 31, and the front of the double-sided yarn-dyed knitted fabric 20 is altered by at least two colored yarns 30, 31, the alteration may be a change in color. In one embodiment, the colors of at least two colored yarns 30, 31 are different.
[0016] The formation of the double-sided yarn-dyed knitted fabric 20 will be described further with reference to Figures 2 and 3. At least two colored yarns 30, 31 are fed in pairs from at least one yarn feed port 61 on the double-sided circular knitting machine 60 and knitted, and each of the multiple lower bed knitting needles 62 for knitting these front loops 21 of the double-sided circular knitting machine 60 moves in one of two trajectories 70, 71 while being controlled by a needle selection device 63, and each of these lower bed knitting needles 62 pulls only one of the at least two colored yarns 30, 31 in each of the two trajectories 70, 71 to produce one of these front loops 21. It should be noted that the trajectory of each of these lower bed knitting needles 62 is generated guided by a group of lower bed cams 64. Part of the paths of the two trajectories 70 and 71 are the same, and the difference between the two trajectories 70 and 71 is that one of the two trajectories 70 and 71 has a portion (reference numeral 72 in the figure) where the needle is pushed out and pulled in twice. Also, each of the multiple upper needles 65 for knitting these reverse loops 22 of the double-sided circular knitting machine 60 pulls at least two colored yarns 30 and 31 to produce one of these reverse loops 22. Thus, in the present invention, each of these front loops 21 contains only one of at least two colored yarns 30 and 31, and the color of each of these front loops 21 is presented by only one of at least two colored yarns 30 and 31, so in the present invention, the presented color of each of these front loops 21 is purer compared to conventional embodiments in which the front loops of double-sided knitting still contain face yarn and ground yarn, and the visual experience of the front of the double-sided yarn-dyed knitting 20 is improved. Furthermore, the structure of the double-sided yarn-dyed knitted fabric 20 of the present invention can solve the problem that conventional double-sided yarn-dyed knitted fabrics, when knitted in multiple colors, have a weight that is not suitable for garment manufacturing and also have a poor feel.
[0017] Referring also to FIGS. 4 to 7, based on the gist of the design of the above embodiments, the present invention provides another double-sided warp-dyed knitted fabric 40, and the double-sided warp-dyed knitted fabric 40 is knitted by a plurality of colored yarns 30, 31, 32, 33. In this embodiment, taking the number of these colored yarns 30, 31, 32, 33 as four as an example, it is not limited thereto. The colors of these colored yarns 30, 31, 32, 33 may be different. These colored yarns 30, 31, 32, 33 can be divided into at least two yarn groups 50, 51. In this embodiment, the number of yarns included in at least two yarn groups 50, 51 is equal, and each of at least two yarn groups 50, 51 includes two of these colored yarns 30, 31, 32, 33. Specifically, each of at least two yarn groups 50, 51 is determined by whether these yarns 30, 31, 32, 33 are fed and knitted from the same yarn supply port 61. That is, two of these colored yarns (30, 31) included in each of at least two yarn groups 50, 51 are fed and knitted from the same yarn supply port 61. Also, each of these front loops 21 is formed by one of two colored yarns 30, 31 (or 32, 33) of at least one of at least two yarn groups 50, 51, and each of these back loops 22 is knitted by all the colored yarns 30, 31 (or 32, 33) included in at least one of at least two yarn groups 50, 51, and the front of the double-sided warp-dyed knitted fabric 40 changes with these colored yarns 30, 31, 32, 33. Also, when the above embodiment is described in industrial terms, it is called two-feed four-color. Based on the same design concept, the present invention can also be implemented with three-feed six-color, two-feed three-color, three-feed five-color, and four-feed seven-color. For an example of two-feed three-color, refer to FIG. 8. In the embodiment of FIG. 8, one of at least two yarn groups 50 includes two of these colored yarns (30, 31), and the other of at least two yarn groups 51 includes one of these colored yarns (32).
[0018] Furthermore, at least two yarn groups 50, 51 may be fed and knitted respectively from two yarn feeding ports 61 arranged sequentially. In one embodiment, one of two adjacent ones in these back loops 22 may be knitted by one of the at least two yarn groups (50), and the other of two adjacent ones in these back loops 22 may be knitted by the other of the at least two yarn groups (51). Referring to FIG. 7, in one embodiment, one of some two adjacent ones in these front loops 21 may be knitted by one of the colored yarns 30, 31 included in one of the at least two yarn groups (50), and the other of two adjacent ones in these front loops 21 may be knitted by one of the colored yarns 32, 33 included in one of the at least two yarn groups (51). Referring to FIG. 8, when one of the at least two yarn groups (51) contains only a single colored yarn (32), those knitted by the yarn group (51) in these front loops 21 all contain only a single colored yarn (32). Also, in one embodiment, each of two adjacent ones in these front loops 21 is knitted by one of the colored yarns 30, 31 (or 32, 33) included in the same one 50 (or 51) in the at least two yarn groups.
