Description

Technical Field

[0001] This invention relates to a double-sided color-woven fabric. Background Technology

[0002] Taiwanese patent TWI852480B discloses the production of yarn-dyed fabrics using a circular knitting machine. However, as understood from the aforementioned patent, the front yarn loops of existing yarn-dyed fabrics are formed by knitting a face yarn and a ground yarn together. The shape of the front yarn loops is altered by changing the relative positions of the face yarn and the ground yarn, thus achieving color change. While the existing method achieves color change, because the face yarn and the ground yarn only change their relative positions, when visually inspecting the front yarn loops, another element (the face yarn is colored, and the ground yarn is the other) can still be seen, resulting in impure color development of the front yarn loops. When observing the yarn-dyed fabric as a whole, problems such as blurriness in the pattern composed of multiple front yarn loops can be observed. Summary of the Invention

[0003] The main objective of this invention is to solve the problem that the color development of the front yarn loops in existing double-sided yarn-dyed fabrics is affected by another non-primary color-developing yarn contained in the yarn loops.

[0004] To achieve the above objectives, the present invention provides a double-sided yarn-dyed fabric comprising a plurality of front yarn loops and a plurality of back yarn loops. The double-sided yarn-dyed fabric is formed by knitting with at least two colored yarns. Each of the plurality of front yarn loops is knitted with one of the at least two colored yarns, and each of the plurality of back yarn loops is knitted with both of the at least two colored yarns. The front side of the double-sided yarn-dyed fabric is varied due to the at least two colored yarns.

[0005] In one embodiment, the at least two yarns are different colors.

[0006] In addition to the foregoing, the present invention also provides another double-sided yarn-dyed fabric comprising a plurality of front yarn loops and a plurality of back yarn loops. The double-sided yarn-dyed fabric is formed by knitting a plurality of colored yarns, which can be divided into at least two yarn groups, one of which contains two of the plurality of colored yarns, and the other yarn group contains at least one of the plurality of colored yarns. Each of the plurality of front yarn loops is formed by one of the colored yarns contained in one of the at least two yarn groups, and each of the plurality of back yarn loops is knitted by all the colored yarns contained in one of the at least two yarn groups. The front side of the double-sided yarn-dyed fabric is varied due to the plurality of colored yarns.

[0007] In one embodiment, one of two adjacent back loops is knitted from one of the at least two yarn groups, and the other back loop is knitted from the other of the at least two yarn groups.

[0008] In one embodiment, one of two adjacent front loops is knitted from one of two colored yarns contained in one of the at least two yarn groups, and the other front loop is knitted from one of the colored yarns contained in the other yarn group of the at least two yarn groups.

[0009] In one embodiment, each of two adjacent front loops is knitted from one of the colored yarns contained in the same yarn group of the at least two yarn groups.

[0010] In one embodiment, the number of the plurality of colored yarns is four, and the number of yarns contained in the at least two yarn groups is equal.

[0011] In one embodiment, the multiple colored yarns are of different colors.

[0012] Compared to common double-sided fabrics, the present invention, through the aforementioned embodiments, has the following characteristics: Each of the multiple front yarn loops in the present invention contains only one colored yarn, and the color of each front yarn loop is presented by only a single colored yarn. Compared to the common implementation of double-sided fabrics where the front yarn loops still include face yarn and ground yarn, the color of each front yarn loop in the present invention is purer, enhancing the visual appeal of the front side of the double-sided yarn-dyed fabric. Furthermore, the structure of the double-sided yarn-dyed fabric of the present invention better solves the problem that common double-sided yarn-dyed fabrics, when subjected to multi-color knitting, result in fabric weight that does not meet garment manufacturing requirements and poor hand feel. Finally, the double-sided yarn-dyed fabric of the present invention breaks through the color limitations of common double-sided yarn-dyed fabrics, and can be configured as one-way two-color, two-way four-color, three-way six-color, two-way three-color, three-way five-color, four-way seven-color, etc., depending on the implementation requirements.

[0021] The detailed description and technical content of the present invention will now be explained with reference to the accompanying drawings:

[0022] Please see Figure 1 and Figure 2 This invention provides a double-sided yarn-dyed fabric 20, which is produced by knitting with a double-sided circular knitting machine 60. The double-sided yarn-dyed fabric 20 includes a plurality of front yarn loops 21 and a plurality of back yarn loops 22. In one embodiment, the double-sided yarn-dyed fabric 20 is formed by knitting with at least two colored yarns 30 and 31. Each of the front yarn loops 21 of the double-sided yarn-dyed fabric 20 is formed by knitting with one of the at least two colored yarns 30 and 31. Each of the back yarn loops 22 of the double-sided yarn-dyed fabric 20 is formed by knitting with the at least two colored yarns 30 and 31 together. The front surface of the double-sided yarn-dyed fabric 20 is varied due to the at least two colored yarns 30 and 31, and the variation may be a color variation. In one embodiment, the at least two colored yarns 30 and 31 are of different colors.

[0023] Please see Figure 2 and Figure 3The formation of the double-sided yarn-dyed fabric 20 is further described below. The at least two colored yarns 30, 31 are fed in pairs by at least one feed nozzle 61 on the double-sided circular knitting machine 60. Each of the plurality of knitting needles 62 of the double-sided circular knitting machine 60 used to knit these front loops 21 is controlled by a needle selector 63 and moves on one of two tracks 70, 71. Each of these knitting needles 62 hooks only one of the at least two colored yarns 30, 31 in each of the two tracks 70, 71 to produce one of the front loops 21. It should be understood that the track of each of these knitting needles 62 is guided by a lower needle bed corner group 64. The partial paths of the two tracks 70, 71 are the same; the difference between the two tracks 70, 71 is that one of the two tracks 70, 71 has a secondary exit and exit section (as shown in the diagram 72). On the other hand, each of the multiple needle bed needles 65 of the double-sided circular knitting machine 60 used to knit these back loops 22 hooks the at least two colored yarns 30, 31 to produce one of these back loops 22. Continuing on, each of the front loops 21 of the present invention contains only one of the at least two colored yarns 30, 31, and the color of each front loop 21 is presented by only one of the at least two colored yarns 30, 31. Compared to the common implementation of double-sided fabrics where the front loops still include face yarn and ground yarn, the color of each front loop 21 of the present invention is purer, enhancing the visual appeal of the front of the double-sided yarn-dyed fabric 20. Furthermore, the structure of the double-sided yarn-dyed fabric 20 of the present invention better solves the problem that common double-sided yarn-dyed fabrics, when knitted with multiple colors, result in fabric weight that does not meet garment requirements and poor hand feel.

[0024] Please see Figures 4 to 7Based on the design spirit of the previous embodiment, the present invention also provides other double-sided yarn-dyed fabrics 40, which are formed by knitting multiple colored yarns 30, 31, 32, and 33. In this embodiment, the number of these colored yarns 30, 31, 32, and 33 is four, but is not limited thereto. The colors of these colored yarns 30, 31, 32, and 33 can be different. These colored yarns 30, 31, 32, and 33 can be divided into at least two yarn groups 50 and 51. In this embodiment, the number of yarns contained in the at least two yarn groups 50 and 51 is equal. Each yarn group in the at least two yarn groups 50 and 51 contains two of these colored yarns 30, 31, 32, and 33. More specifically, each yarn group in the at least two yarn groups 50 and 51 is determined based on whether these yarns 30, 31, 32, and 33 are fed into the knitting machine by the same yarn feeder 61. That is, two of the colored yarns 30 and 31 contained in each yarn group in the at least two yarn groups 50 and 51 are fed into the knitting machine by the same yarn feeder 61. Furthermore, each of the front yarn loops 21 is formed by one of two colored yarns 30, 31 (or 32, 33) from one of the at least two yarn groups 50, 51, and each of the back yarn loops 22 is knitted by all the colored yarns 30, 31 (or 32, 33) contained in one of the at least two yarn groups 50, 51, thus changing the front side of the double-sided yarn-dyed fabric 40 due to these colored yarns 30, 31, 32, 33. Moreover, the foregoing embodiment is referred to in industry terms as two-color four-color, and the present invention can also be implemented with three-color six-color, two-color three-color, three-color five-color, and four-color seven-color based on the same design spirit. Taking two-color three-color as an example (see [link]). Figure 8 ),At Figure 8 In one embodiment, one of the at least two yarn groups 50 includes two of the colored yarns 30, 31, and the other yarn group of the at least two yarn groups 51 includes another colored yarn 32.

[0025] Furthermore, the at least two yarn groups 50, 51 can be knitted by being fed into the yarn by two sequentially arranged yarn feeders 61. In one embodiment, one of the two adjacent back loops 22 is knitted by one of the at least two yarn groups 50, and the other back loop is knitted by the other yarn group 51 of the at least two yarn groups. See again Figure 7 In one embodiment, one of the adjacent front loops 21 is knitted from one of the colored yarns 30, 31 included in one of the at least two yarn groups 50, and the other front loop is knitted from one of the colored yarns 32, 33 included in the other yarn group 51 of the at least two yarn groups. See again Figure 8When one of the at least two yarn groups 51 contains only a single-colored yarn 32, the front loops 21 formed by the aforementioned yarn group 51 all contain only a single-colored yarn 32. Alternatively, in one embodiment, each of two adjacent front loops 21 is formed by knitting one of the colored yarns 30, 31 (or 32, 33) contained in the same yarn group 50 (or 51) of the at least two yarn groups.
