The following is a description of a method of knitting a double-sided fabric having cut loop pile 44 by a circular knitting machine, the method comprising:

knitting the first fabric layer 41: knitting the first fabric layer 41 using the first knitting mechanism 1;

knitting the second cloth layer 42: the knitting hook 24 on the second knitting mechanism 2 feeds the wool yarn 31, then the knitting needle 22 on the second knitting mechanism 2 simultaneously inserts the wool yarn 31 and the ground yarn 32, the knitting needle 22 weaves a second cloth layer 42, namely ground yarn tissue, forms a loop 45 connected with the ground yarn 32 through the knitting hook 24 and drives the knitting knife 23 on the second knitting mechanism 2 to cut the loop 45 to form a cut loop velvet 44 connected with the ground yarn 32, and the velvet of the cut loop velvet 44 is driven to pass through the through groove 212 on the needle bed 21 of the second knitting mechanism 2 through air and enter the needle bed 21; and

an interweaving step:

knitting needles

12 and 22 of the first knitting mechanism 1 and the second knitting mechanism 2 are simultaneously used for interlacing, and the first fabric layer 41 and the second fabric layer 42 are connected by a plurality of connecting yarns 33 to knit a double-sided fabric having a cut loop pile 44.

Thereafter, the needle bed 21 drives one of the weaving blades 23 to cut the loop 45 hung on the weaving hook 24, so that the loop 45 is cut to form one of the cut loops 44 connected with the base yarn 32. Further, the length of the cut loop pile 44 is determined by the length of the yarn hooked by one of the hooks 24 when the loop 45 is formed. After the second fabric layer 42 is knitted, the knitting process is performed, and when the knitting process is performed, the first knitting mechanism 1 and the second knitting mechanism 2 of the circular knitting machine are driven simultaneously, so that the connecting yarns 33 connect the first fabric layer 41 and the second fabric layer 42 in a half-needle knitting or full-needle knitting manner.

Here, if the needle bed 11 of the first knitting mechanism 1 is an upper plate to which the knitting needle 12 of the first knitting mechanism 1 is correspondingly attached, the needle bed 21 of the corresponding second knitting mechanism 2 is a lower cylinder to which the knitting needle 22, the needle bar 23, and the needle hook 24 of the second knitting mechanism 2 are correspondingly attached; on the other hand, if the needle bed 11 of the first knitting mechanism 1 is a lower cylinder on which the knitting needle 12 of the first knitting mechanism 1 is correspondingly mounted, the needle bed 21 of the corresponding second knitting mechanism 2 is an upper cylinder on which the knitting needle 22, the knitting blade 23, and the knitting hook 24 of the second knitting mechanism 2 are correspondingly mounted.

The position of the needles 200 of the lower disc assembly, the position of the first hook 300, the position of the second hook 400 and the position of the knife 500 are all located in the third section 603. When the knitting needle 200 and the first hook 300 of the lower disc component reach the highest point, the vertical distance between the highest point and the needle cylinder opening is Ymm, and Y is less than or equal to l ₂ . At this time, the knitting needle 200 and the first hook 300 of the lower disc assembly simultaneously pick up the wool yarn. At this time, the second hook 400 and the knife 500 of the lower disc assembly are in an inoperative condition.

And a fourth path: the lower disc finishes the wool yarn hanging, and the needle does not drop off the loop. The first needle section of the upper disk assembly and the second needle section of the upper disk assembly float. The position of the needles 200 of the lower disc assembly, the position of the first hook 300, the position of the second hook 400 and the position of the knife 500 are all located in the fourth section 604.

When the first hook 300 of the lower disc assembly reaches the lowest point, the knitting needle 200 of the lower disc assembly hangs one ground yarn. And after the bottom yarn is hung for the first time on the lower disc assembly, narrowing and knocking over. At this time, the second hook 400 and the knife 500 of the lower disc assembly are in an inactive state. The upper disc assembly and the lower disc assembly work independently in the fifth path.

A sixth path: and hanging bottom yarns on the lower disc for the second time. The position of the needles 200, the position of the first hook 300, the position of the second hook 400 and the position of the knife 500 of the lower disc assembly are all located in the sixth section 606.

And (5) narrowing the knitting needle 200 of the lower disc assembly after the bottom yarn is hung for the second time to finish the wool binding yarn. At this time, the first needle section of the upper disc assembly, the second needle section of the upper disc assembly, the first hook 300 of the lower disc assembly, the second hook 400 and the weaving knife 500 are all in the inactive state.

A seventh way: first hook 300 is replaced with second hook 400. The second hook 400 cycles according to the first pass → the sixth pass of the first hook 300. The first hook 300 cycles according to the first pass → the sixth pass of the second hook 400. Other parts of the upper disc assembly and the lower disc assembly are circulated according to the first path → the sixth path, and the upper disc assembly and the lower disc assembly work for eleven paths to form a working cycle.

In the fourth or tenth way, the lowest point of the first hook 300 or the second hook 400 sinking is the distance Zmm from the first hook head 301 or the second hook head 401 to the spring of the cylinder, and the calculation formula is as follows: z = l ₄ Y-W-N, where W is the distance between the first hook 301 or the second hook 401 and the mouth of the needle cylinder when the first hook 300 or the second hook 400 is not operating, and N is the width of the spring of the needle cylinder 100. At the same time, | ₈ Not more than W, the wool yarn cut by the weaving knife 500 can reach the back position of the needle cylinder 100.
