Description

TECHNICAL FIELD The present invention relates to a weft knitted fabric and its knitting method, and more particularly to a weft knitted fabric and its knitting method comprising a mesh and a yarn-dyed jacquard at the same time.

In conventional weft knitted fabrics, when changing the color of the surface of a knitted fabric having a mesh structure, it can only be done by a method of dyeing after knitting, and cannot be realized by yarn dyeing. Also, conventional weft knitted fabrics with yarn-dyed jacquard do not have a mesh structure. Therefore, the applicant proposes a technical solution to solve the problem.

SUMMARY OF THE INVENTION The main object of the present invention is to solve the problem that yarn-dyed jacquard cannot be applied to conventional weft knitted fabrics having a mesh structure.

In order to achieve the above object, the present invention provides a weft knitted fabric knitted with a front yarn and a ground yarn using a circular knitting machine. The weft knitted fabric includes at least one first block and at least one second block, each of the at least one first block and the at least one second block includes at least one course, and the In the first block, all the surface threads and the base threads are looped, the relative positions of the surface threads and the base threads are not constant in the same course, and in the second block, the base threads are all looped, The front yarn is combined with the ground yarn in either loop or welt .

In one embodiment, the weft knit includes a plurality of the first blocks and a plurality of the second blocks, the plurality of the first blocks and the plurality of the second blocks being alternately formed.

In one embodiment, in the second block, the face yarn loops with the ground yarn both before and after welting .

In one embodiment, the color of the front yarn is different than the color of the ground yarn.

Furthermore, the present invention provides a method of knitting a weft knitted product that is knitted with the front yarn and the base yarn and is carried out by a circular knitting machine, and the knitting method of the weft knitted product comprises:
The circular knitting machine selectively feeds the surface yarn and the base yarn by either the standard yarn supply or the reverse yarn supply in knitting the same course, thereby forming a loop of the surface yarn and the base yarn. that the relative position after knitting is not constant in the same course,
In the knitting of the same course, the circular knitting machine selects needles so that all the ground threads are looped and the front threads are combined with the ground threads by knitting the loops or by hooking the threads on the needles to form a welt. and controlling.

In one embodiment, the face yarns are knitted into loops by both the knitting before the yarn is hooked into the welt and the knitting afterward.

In one embodiment, the color of the front yarn is different than the color of the ground yarn.

The invention, implemented as described above, has the following advantages over the prior art. The weft knitted fabric of the present invention comprises both the mesh and the yarn-dyed jacquard.

FIG. 1 is a structural schematic diagram of the weft knitted fabric of the present invention. FIG. 2 is a schematic diagram of the block distribution of the weft knitted fabric of the present invention. FIG. 3 is a schematic diagram of the knitting programming of the weft knitted fabric of the present invention.

The detailed technical content of the present invention will be described below in conjunction with the drawings.
As shown in FIG. 1, the present invention provides a weft knitted fabric 20 knitted with a front yarn 30 and a ground yarn 31 using a circular knitting machine (not shown). In one embodiment, the color of face yarn 30 is different than the color of ground yarn 31 . When viewed from the front of the weft knitted fabric 20, the weft knitted fabric 20 includes at least one first block 21 and at least one second block 22, and at least one first block 21 and at least one second block 22. each include at least one course 23 (Course). The number of at least one course 23 included in the first block 21 is not necessarily equal to the number of at least one course 23 included in the second block 22, and the sizes of the first block 21 and the second block 22 are Can be adjusted according to design needs.

Furthermore, in the first block 21 of the weft knitted fabric 20 of the present invention, the surface yarns 30 and the base yarns 31 are all looped, and the relative positions of the surface yarns 30 and the base yarns 31 are not constant in the same course 23 . Therefore, in the first block 21 of the weft knitted fabric 20 of the present invention, the front yarn 30 is not necessarily positioned on one side of the weft knitted fabric 20, and the position of the ground yarn 31 may be changed. The color in the first block 21 of the knit 20 is not due to the face yarns 30 alone. In addition, in the second block 22 of the weft knitted fabric 20 of the present invention, the ground yarns 31 are all looped, and the front yarns 30 are combined with the ground yarns 31 either in loops or welts . Furthermore, the expression that the front yarn 30 loops means that the front yarn 30 and the ground yarn 31 are simultaneously pulled by at least one knitting needle to form a loop. Welting the front yarn 30 means that the yarn is hung on a needle. is formed. Further, the surface yarn 30 loops with the base yarn 31 both before welting and after knitting. As a result, in the second block 22 of the weft knitted fabric 20, the ventilation effect can be improved by forming the mesh.

As shown in FIG. 2, the weft knitted fabric 20 of the present invention includes a plurality of first blocks 21 and a plurality of second blocks 22, wherein the plurality of first blocks 21 and the plurality of second blocks 22 are alternately It is formed. Furthermore, the size of each first block 21 is not necessarily the same, and the size of each second block 22 is not necessarily the same as the size of each first block 21. are not necessarily the same size.

As shown in FIGS. 1 and 3, in FIG. 3, ◯ represents knitting of the front yarn 30, ▪ represents knitting of the ground yarn 31, and W represents hooking the front yarn 30 to the needle. Furthermore, the present invention provides a method of knitting a weft knitted fabric 20 that is knitted with a front yarn 30 and a ground yarn 31 and is performed by the circular knitting machine, and the method of knitting the weft knitted fabric 20 is as follows:
The circular knitting machine selectively feeds the surface yarn 30 and the base yarn 31 by either the standard yarn supply or the reverse yarn supply in knitting the same course 23, so that the surface yarn 30 and the base yarn 31 are fed. that the relative positions after knitting the loops are not constant in the same course 23 (eg row 41 in FIG. 3);
In the knitting of the same course 23, the circular knitting machine selects needles so that all the base yarns 31 knit loops and the front yarns 30 are combined with the base yarns 31 by knitting loops or welting the yarns by hooking them on needles. (eg, column 42 in FIG. 3).

The two operations described in the above knitting method are for forming the first block 21 and the second block 22 of the weft knitted fabric 20 of the present invention, respectively. Provided that the circular knitting machine completes a single course 23, in other words the same course 23 cannot be changed arbitrarily. In addition, the order of the two operations is not fixed and can be determined by programming. In the operation of the circular knitting machine knitting the first block 21, by means of a color changing device (e.g. US10669658, TWI672405) or by controlling the operation of at least one sinker (e.g. JP7089126) or the retraction time of the at least one knitting needle. (eg US11136698) can realize normal and reverse yarn feeding. In the operation of knitting the second block 22 by the circular knitting machine, the knitting parts are controlled by a needle selector (not shown) so that the front yarn 30 is added to the knitting or the yarn is hung on the needle. , looped in combination with the ground thread 31 , or welted against the ground thread 31 .
