Description

method for knitting needle-turning structural pattern by empty needle

Technical Field

The invention relates to the field of a pattern knitted fabric knitting method, in particular to a method for knitting a pattern of a needle-turning structure by using an empty needle.

Background

along with the improvement of the intelligent mechanical manufacturing industry level in China, the electromechanical integrated high-tech product computerized flat knitting machine is widely applied to the production of the knitting industry. The product of the computerized flat knitting machine is knitted fabric, the knitted fabric is formed by connecting coils in the transverse direction and stringing the coils in the longitudinal direction, and the process of forming the coils on the flat knitting machine is as follows: the method comprises the following steps of (old coil) removing a loop, padding yarn, carrying yarn, closing a loop, looping, linking, bending yarn, knocking over, looping and drawing, namely: one of the conditions for forming the coil is that an old coil must be present and a new coil is formed by knocking over the old coil. When the knitting needle of the flat knitting machine has no old loop (empty needle), the normal loop cannot be knitted, and only the hook of the knitting needle contains the yarn (suspension arc line), which is not the normal loop.

Disclosure of Invention

The invention solves the technical problem of providing a method for knitting a pattern of a needle turning structure by using an empty needle, when an old coil (the empty needle) does not exist on a knitting needle of a flat knitting machine, a normal coil cannot be knitted, only a needle hook of the knitting needle contains a yarn (a suspension arc line), and the suspension arc line is turned to the other needle bed to be superposed with a basic tissue to form the pattern tissue of the needle turning structure.

The technical scheme of the invention is as follows: a method for knitting needle-turning structural patterns by empty needles comprises the following knitting procedures:

The first process step: on a needle bed of a flat knitting machine, under the condition of old loops, sequentially finishing loop withdrawing, yarn laying, yarn carrying, opening closing, looping, loop connecting, yarn bending, loop releasing, looping and drawing to form a basic tissue;

And a second step: on the other needle bed of the flat knitting machine, no old loop exists, empty needles are knitted, no old loop knocking-over process exists on a knitting needle, and only a suspension arc line is contained in a hook of the knitting needle;

And a third step of: on the basis of the first process and the second process, the coils connected with the old coils are used as basic tissues, the length of the suspension arc line knitted by the empty needle is matched with the number of the rows knitted by the basic tissues, and the integral or local needle turning is overlapped with the basic tissues to form a new structural pattern.

Preferably, the basic structure in the third step is mainly a single-sided structure, the suspension arc lines can be overlapped for multiple times, the length of the suspension arc lines is matched with the number of the rows woven by the basic structure, and the suspension arc lines are freely combined for weaving, so that various empty needle weaving needle overturning structural patterns can be formed.

The invention has the following beneficial effects: (1) the invention perfects the technical problem that the empty needle can not form a normal coil. (2) The normal loops are realized under the condition of meeting the geometric condition of loop formation, but the invention expands that the empty needles can not weave the normal loops, is not connected by the serial sleeves, realizes the structural pattern through the knitting technology and expands the structure of the empty needle knitted fabric tissue. (3) The invention does not need to modify the prior equipment and add other instruments, and the technical method of the invention can be applied to any flat knitting machine product.

Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples. The method comprises the following specific steps:

Implementation mode one

The method for knitting a needle-flipping structural pattern by using an empty needle is a method for integrally flipping a needle of the needle-flipping structural pattern by using an empty needle, and knitting needs to be suspended alternately by a front needle bed and a rear needle bed in a knitting process, and specifically as shown in fig. 3, the following is realized:

During the knitting process, the front needle bed and the back needle bed need to be alternately paused, and as shown in fig. 3 in particular, the following method is provided:

(1) step 1, as shown in the figure, the mark S1, the back needle bed weaves the basic tissue, at this time, the knitting needles on the front needle bed do not participate in the knitting, and are all empty needles.

(2) The basic structure on the back needle bed is suspended for knitting, and the knitting of an empty needle is waited:

Step 2, as shown in the figure, the mark is S2, a rear needle bed knitting needle A, B is used for knitting a normal coil, and front needle bed empty needles a and b are used for knitting a suspension arc line; step 3, marking S3 as shown in the figure, then knitting a normal coil by a rear needle bed knitting needle C, D, and knitting a suspension arc by front needle bed empty needles c and d; step 4, as shown in the figure, the mark S4, and similarly, the back needle bed knitting needle E, F is used for knitting normal coils, and the front needle bed empty needles e and f are used for knitting suspension arcs; step 5, marking S5 as shown in the figure, and finally knitting a normal coil by a rear needle bed knitting needle G, H and knitting a suspension arc by a front needle bed only by an empty needle g;

(3) the suspension arc line on the front needle bed is suspended for weaving, and the weaving of the basic tissue is waited:

The number of courses woven by the basic tissue is matched with the length of the arc line, particularly the length of Aa determines how many courses need to be woven by the basic tissue, and in the example, the basic tissue continuously weaves 8 courses which are matched with the length of Aa.

(5) Step 7, as shown in the figure, marked by S7, because the lengths of Aa, Cc, Ee and Gg are basically the same, and the lengths of gH, Ff, Dd and Bb are basically the same, the suspension arcs knitted by the empty needles a, b, c, d, e, f and g on the front needle bed are turned over to the back needle bed at one time integrally to be overlapped with the stitches of the basic tissue; step 8, as shown in the figure, labeled S8, so far, the weaving of a structural pattern is completed. The structural pattern is shown in figure 4, and the twill structure of the fabric is formed by suspension arc lines.

second embodiment
