The invention relates to a weft-knitted fabric and a knitting method thereof, and more particularly to a weft-knitted fabric with both mesh and yarn-dyed jacquard and a knitting method thereof.
If existing weft-knitted fabrics intend to change the surface color of the fabric with a mesh structure, it can only be implemented through dyeing after knitting, and cannot be realized by yarn-dyeing. Similarly, the existing weft-knitted fabrics with yarn-dyed jacquard also do not have a mesh structure, so the applicant of the invention earnestly comes up with a technical solution to solve the aforementioned problems.
A main object of the invention is to solve the problem that existing weft-knitted fabrics with mesh structure cannot have yarn-dyed jacquard.
In order to achieve the above object, the invention provides a weft-knitted fabric, produced by a circular knitting machine and formed by knitting a face yarn and a ground yarn, including at least one first area and at least one second area. The at least one first area and the at least one second area respectively comprise at least one course, in the first area, the face yarn and the ground yarn are all looped, relative positions of the face yarn and the ground yarn are not fixed in the same course, and in the second area, the ground yarn is all looped, and the face yarn cooperates with the ground yarn by one of following: looping and welting.
In one embodiment, the weft-knitted fabric comprises a plurality of first areas and a plurality of second areas, and the plurality of first areas and the plurality of second areas are alternately arranged.
In one embodiment, in each of the plurality of second areas, the face yarn is looped with the ground yarn before and after the face yarn which is welted.
In one embodiment, a color of the face yarn is different from a color of the ground yarn.
In addition to the above, the invention further provides a knitting method of a weft-knitted fabric, implemented with a circular knitting machine, the circular knitting machine using a face yarn and a ground yarn to knit, comprising:
In one embodiment, the face yarn is knitted into loops with the ground yarn before and after the face yarn which is welted by missing needle.
In one embodiment, a color of the face yarn is different from a color of the ground yarn.
Through the foregoing implementation of the invention, compared with the prior art, the invention has the following features: the weft-knitted fabric of the invention has mesh and yarn-dyed jacquard at the same time.
The detailed description and technical content of the invention are described below with reference to the accompanying drawings.
Please refer to
In the first area 21 of the weft-knitted fabric 20 of the invention, the face yarn 30 and the ground yarn 31 are all looped, and relative positions of the face yarn 30 and the ground yarn 31 are not fixed in the same course 23. Therefore, in the first area 21 of the weft-knitted fabric 20 of the invention, the face yarn 30 is not absolutely positioned on one side of the weft-knitted fabric 20, but has a position exchanged with the ground yarn 31, so that a color development of the weft-knitted fabric 20 in the first area 21 is not simply caused by the face yarn 30. On the other hand, in the second area 22 of the weft-knitted fabric 20 of the invention, the ground yarn 31 is all looped, and the face yarn 30 cooperates with the ground yarn 31 by one of following: looping and welting. Further, looping of the face yarn 30 means that the face yarn 30 and the ground yarn 31 are hooked by at least one knitting needle to form a yarn loop at the same time. Welting of the face yarn 30 refers to implementation of missing needle, the face yarn 30 does not form the yarn loop together with the ground yarn 31 at that moment, so that a mesh is formed on a surface of the weft-knitted fabric 20. Further, the face yarn 30 before and after welting of the face yarn 30 are looped with the ground yarn 31. Thereby, ventilation effect of the weft-knitted fabric 20 in the second area 22 can be enhanced due to formation of the mesh.

The two actions described above in the knitting method are respectively used to form the first area 21 and the second area 22 of the weft-knitted fabric 20 of the invention, and switching timepoint between the two actions is limited by using the circular knitting machine to complete one of the single course 23, that is to say, the two actions cannot be changed arbitrarily in the same course 23. Furthermore, a sequence of the aforementioned two actions is not limited, and can be determined according to programming. During knitting action of the circular knitting machine to form the first area 21, a color-changing device (such as U.S. Pat. No. 10,669,658, TWI672405) can be used, or movement of at least one sinker can be controlled (such as JP7089126), or by controlling a retracting time of the at least one knitting needle (such as U.S. Pat. No. 11,136,698) to realize normal yarn feeding and reverse yarn feeding. On the other hand, during knitting action of the circular knitting machine to form the second area 22, a needle selector (not shown in the figures) can be used to control components used for knitting so that the face yarn 30 is capable of participating in knitting or missing needle, and then cooperating with the ground yarn 31 to form a loop, or producing welting relative to the ground yarn 31.
