needles

22, 12, the

blades

23, 13, the

hooks

24, 14 move.

Further, the first knitting mechanism 1 is different from the second knitting mechanism 2 in that the needle bed 11 of the first knitting mechanism 1 is the upper needle bed, and the needle bed 21 of the second knitting mechanism 2 is the lower needle bed, and in that the number of knitting needles, the number of knitting hooks, the number of knitting knives, and the number of through grooves of the first knitting mechanism 1 and the second knitting mechanism 2 are different depending on the degree of fluff removal in the first cloth layer 41 and the second cloth layer 42. It is still further noted that the number of hook assemblies in the first knitting mechanism 1 and the second knitting mechanism 2 is the same or different by an integral multiple.

The following is a description of a method for knitting a double-sided fabric with cut pile on a circular knitting machine, the method comprising:

knitting the first fabric layer 41: the knitting hook 14 on the first knitting mechanism 1 feeds wool yarn 31, then the knitting needle 12 on the first knitting mechanism 1 simultaneously inserts the wool yarn 31 and the ground yarn 32, the knitting needle 12 knits a first cloth layer 41, namely ground yarn tissue, forms a loop 45 connected with the ground yarn 32 through the knitting hook 14 and drives the knitting knife 13 on the first knitting mechanism 1 to cut the loop 45 to form cut loop velvet 44 connected with the ground yarn tissue, the air blowing device 15 generates air, and the velvet of the cut loop velvet 44 is driven to pass through a through groove 112 on the needle bed 11 of the first knitting mechanism 1 through the air and enter the needle bed 11;

knitting the second cloth layer 42: the knitting hook 24 on the second knitting mechanism 2 feeds the wool yarn 34, then the knitting needle 22 on the second knitting mechanism 2 simultaneously feeds the wool yarn 34 and the ground yarn 35, the knitting needle 22 weaves a second cloth layer 42, namely ground yarn tissue, forms a loop 48 connected with the ground yarn 35 through the knitting hook 24 and drives the knitting knife 23 on the second knitting mechanism 2 to cut the loop 48 to form a cut loop velvet 47 connected with the ground yarn tissue, and the velvet of the cut loop velvet 47 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 interleaving 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 cut loop pile.

It should be further noted that the knitting principles of the steps of knitting the first fabric layer 41 and the second fabric layer 42 are substantially the same, except that the two knitting steps have different degrees of sparseness of cut pile.

Further explaining the method of the present invention, the first fabric layer 41 is knitted by the first knitting mechanism 1, during the knitting process, the needle bed 11 of the first knitting mechanism 1 is fed with the wool yarn 31 and the ground yarn 32, wherein the ground yarn 32 is knitted into the ground yarn structure by the knitting needles 12, and the wool yarn 31 is hooked except for being connected with the ground yarn 32 structure by the hooks 14, that is, the wool yarn 31 is pulled down by one of the hooks 14 to form one of the loops 45. Thereafter, the needle bed 11 drives one of the knitting blades 13 to cut the loop 45 hung on the hook 14, so that the loop 45 is cut to form one of the cut loops 44 connected to the ground yarn 32. Further, the length of the cut loop pile 44 is determined by the length of the yarn that is caught by one of the hooks 14 when the loop 45 is formed.

Subsequently, the knitting step of the second fabric layer 42 is performed by the second knitting mechanism 2, and the knitting step of the first fabric layer 41 may refer to the knitting step of the second fabric layer 42.

After the second fabric layer 42 is knitted, the knitting process proceeds to the interweaving step, in which the first knitting mechanism 1 and the second knitting mechanism 2 of the circular knitting machine are driven simultaneously to connect the first fabric layer 41 and the second fabric layer 42 by half-needle interweaving or full-needle interweaving the connecting yarns 33.

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. In the drawings of the present embodiment, the needle bed 11 of the first knitting mechanism 1 is an upper plate, and the needle bed 21 of the second knitting mechanism 2 is a lower tube.

In conclusion, the method of the invention enables the double-sided cloth with cut loop pile to be directly woven by the circular knitting machine, thereby solving the problem of complicated production procedures derived from the conventional manufacturing method. In addition, the double-sided cloth with the cut loop pile does not need to use glue to adhere the two cloth layers, so that the harm of glue residual substances to the health of a human body is avoided.

In the tenth pass, the position of the knitting needle 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 fourth section 604. The lowest point of the second hook 400 is the distance Zmm between the second hook head 401 and the spring of the needle 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. In this example, W =22mm, n =4mm, z =54-18-22-4=10mm.

An eleventh way: the upper disc is hung with the yarn, and the lower disc is hung with the bottom yarn for the first time. And needles of the first needle section of the upper disk assembly and needles of the second needle section of the upper disk assembly are raised, and the needles are retracted after yarns are hung, so that the tasks of hanging the yarns on the disk are completed. 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 fifth section 605. At this time, the knitting needle 200, the first hook 300, the second hook 400, and the cutter 500 of the lower disc assembly are all in the inactive state. When the second hook 400 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 first hook 300 and the knife 500 of the lower disc assembly are in an inoperative state.

The twelfth way: and hanging bottom yarns on the lower disc for the second time. The knitting needle 200 of the lower disc assembly hangs a bottom yarn for the second time and can fix wool yarn. 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 knife 500 are all in the inactive state.
