This is prior art and will not be elaborated here.

[0027] Its knitting structure includes the following steps:

[0028] Step 1: Through the action of the selector 11, the crochet needles 8 push out needles, the first - stage needles 21 push out needles and form loops, the second - stage needles 22 are in a floating - thread state, and high - pile yarn is fed in.

[0029] Step 2: The high-pile yarn is hooked by the crochet hook 8 and hung on the first section of needles 21, and the needles are drawn in. The sinker piece 122 is retracted to make the high-pile yarn loop on the first loop-forming thread to pre-form a loop. The sinker piece 122 is pushed in, and the first pre-shaping of the high-pile yarn is completed. The crochet hook 8 enters the high-pile needle track and waits to form a loop and be shaped together with the tying yarn later;

[0030] Step 3: Under the action of the needle selector 11, the crochet hook 8 protrudes the needle, and the second section of needles 22 protrudes the needle to form a tuck. The first section of needles 21 floats the yarn to continue pre-shaping the state of the high-pile yarn, and the low-pile yarn is fed in;

[0031] Step 4: The low-pile yarn is hooked by the crochet hook 8 and hung on the second section of needles 22, and the needles are drawn in. The sinker piece 122 is retracted to make the low-pile yarn loop on the first loop-forming thread to pre-form a loop. The sinker piece 122 is pushed in, and the first pre-shaping of the low-pile yarn is completed. The crochet hook 8 enters the low-pile yarn needle track and waits to form a loop and be shaped together with the tying yarn later;

[0032] Step 5: The first section of needles 21 and the second section of needles 22 protrude the needles simultaneously, the needle tongues turn out to open the second loop-forming thread, inside the first loop-forming thread but not passing through the first loop-forming thread. The sinker piece 122 is retracted to make the high-pile yarn and the low-pile yarn on the first loop-forming thread slide into the second loop-forming thread simultaneously and be drawn into the second loop-forming thread when being drawn in together with the fed tying yarn. The sinker piece 122 is pushed in, and the high-pile yarn and the low-pile yarn are shaped;

[0033] Step 6: The first section of needles 21 and the second section of needles 22 protrude the needles simultaneously, the needle tongues turn out to open the first loop-forming thread, and the bottom yarn is fed and drawn into the second loop-forming thread to form a loop when the needles are drawn in. The sinker piece 122 is pushed in;

[0034] Step 7: The knitting needles 2 are in a floating yarn state. The high-pile yarn and the low-pile yarn are sorted out by the lower cam 7. After the cutting tension is appropriate for each, the cutter 9 protrudes the needle to cut, and then the needles are drawn in to form a two-color jacquard high-low plush fabric.

[0035] Specifically:

[0036] Route 1: The needle selector 11 works, acting on the connecting needle 10 to drive the crochet hook 8 to protrude the needle and then draw in the needle, the cutter 9 knits plain, the knitting needles 2 protrude the needle and then knit plain and then draw in the needle, and the sinker piece 122 knits plain and then draws in the needle and then protrudes the needle;

[0037] Route 2: The needle selector 11 works, acting on the connecting needle 10 to drive the crochet hook 8 to protrude the needle and then draw in the needle, the cutter 9 knits plain, the knitting needles 2 protrude the needle and then knit plain and then draw in the needle, and the sinker piece 122 knits plain and then draws in the needle and then protrudes the needle;

[0038] Route 3: The crochet hook 8 knits plain, the cutter 9 knits plain, the knitting needles 2 protrude the needle and then draw in the needle, and the sinker piece 122 knits plain and then draws in the needle and then protrudes the needle;

[0039] Route 4: The crochet hook 8 knits plain, the cutter 9 knits plain, the knitting needles 2 protrude the needle and then draw in the needle, and the sinker piece 122 knits plain and then draws in the needle and then protrudes the needle;

[0040] The 5th path: 8 plain stitches with the crochet hook, casting off the stitches after the cutter 9 has emerged, 2 plain stitches with the knitting needle, 122 plain stitches with the sinker plate.

[0041] The working mode of the present invention is as follows: In this three-position two-color jacquard plush machine, by adding the sinker plate auxiliary device 12, after the first crochet hook 8 has emerged and fed the high-pile yarn, the stitches are cast off. The throat of the sinker plate 122 presses on the high-pile yarn. At this time, the first emerging and casting-off design is for high pile. After the second crochet hook 8 has emerged and fed the low-pile yarn and added the binding yarn, the stitches are cast off. At this time, the second emerging and casting-off is for low pile. Thus, a three-position two-color jacquard plush fabric with two raw materials and two pile heights can be made on one path. For the existing technology, refer to Figure 7 As shown, when the crochet hook 8' emerges to the highest point, when the control latch needle 10' disengages from the crochet hook 8', the stitch of the crochet hook 8' travels along the crochet hook track 72' to knit the low pile. When the control latch needle 10' combines with the crochet hook 8', the stitch of the latch needle 10' travels along the latch needle track 73', and drives the crochet hook 8' to travel along the latch needle track 73' to knit the high pile. Then, the yarn is cut by the cutter 9' to achieve a high-low pile jacquard plush fabric with one-path yarn feeding. Compared with the existing technology, the jacquard plush fabric knitted by this knitting structure has products with two raw materials and two pile heights, improving the aesthetics of the knitted products. Moreover, this knitting structure is simple, has high knitting efficiency, and at the same time, the pile surface of the knitted product is soft, firm, not easy to shed hair, thus enhancing the market competitiveness of the knitted products.

[0042] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the protection scope of the present invention.
