Designing the density: the transverse density of the finished product is 32 needles/10 cm, and the longitudinal density of the finished product is 26 rows/10 cm.

Parameters of the flat knitting machine:

the knitting principle or knitting form of the computer flat knitting machine generally comprises six needle outlet heights of looping, tucking, floating, needle turning, needle receiving and needle releasing.

1. Looping (knitting): forming a new stitch, i.e. looping, by the needle-out height 3/4;

2. tucking (hanging mesh): the needle outlet height 2/4 forms a tuck hanging mesh;

3. float (non-woven): the height of the needle is 0, the needle can not be drawn out, the belt yarn does not participate in the knitting action, and the floating thread is pulled;

4. needle turning: needle out height 4/4 forms a needle flip;

5. needle connecting: the stitch height 1/4 receives stitches on the tuck stitch;

6. knockover (no knit): the needle-out height 3/4, needle-up, no yarn knitting, latch closing, stitch drop from knitting needle.

The knitting process of the thick-needle type full-forming style product can be realized by combining the 6 knitting forms with a multi-needle-pitch spacing knitting technology and performing stitch turning and shifting actions of the stitches by means of the empty needle positions of the opposite needle plates.

FIG. 6a is a plan view of a needle-separated knitted loop of the present invention; as shown in FIG. 6b, it is a design view of the needle-separating knitted stitch according to the present invention.

The technical method for knitting the fully formed product by the needle separating technology specifically comprises the following steps:

step 1: knitting a cylindrical air layer as a base weave structure through a needle;

the base structure is the base for knitting multi-gauge products, 1-space-1 needle is adopted for needle withdrawing, and front and rear plate coils are knitted in a circular manner, so that the cylindrical air layer base structure can be knitted.

The yarn is introduced from the direction of the front plate (I), the odd needles of the 1 st, 3 rd and 5 th 5 … … needles are drawn out to knit a new loop, and the even needles of the front plate (2 nd, 4 th and 6 th 6 … … needles) are not drawn out, not knitted and drawn floating, and only the yarn passes through the knitting needle;

when the yarn is drawn out from the direction of the back plate II, the 2 nd, 4 th and 6 … … th even needles are drawn out to knit new loops, the 1 st, 3 rd and 5 … … th odd needles of the back plate are not drawn out, not knitted and float, only the yarn passes through the knitting needle, and the front plate wheel and the back plate wheel knit new loops again.

The front plate and the rear plate are knitted according to the staggered needle position, namely when the front plate is knitted, the rear plate is not knitted, or when the rear plate is knitted, the front plate is not knitted, so that the cylindrical air layer structure knitted by adopting the multi-gauge needle separation technology has no obvious difference with the structural appearance effect knitted by normal gauge.

As shown in FIG. 7, it is a schematic diagram of a twist pattern design according to the present invention.

The weaving process is described by taking the example that 2 needles press 2 needles of the twisted yarn and the direction is right pressing left, the staggered plate needle number of the table concentrator is an even number of needles, and the staggered plate needle number of the table concentrator is a multiple of the needle number of the twisted yarn.

When the front plate is twisted, firstly, front plate coils crossed by the twisted are turned over to the empty needle positions of the rear plate, at the moment, the needle positions of the front plate twisted are empty, then, coils of the rear plate on the right side are turned over to the needle positions on the left side corresponding to the front plate after being leftwards shaken by 4 needle positions, and finally, coils of the rear plate on the left side are turned over to the needle positions on the right side corresponding to the front plate after being rightwards shaken by 4 needle positions, so that the cross exchange of the coils on the right side and the left side of the front plate is completed. In a similar way, the rear plate twist principle is completely the same as the front plate twist principle, the purpose of respectively twisting the front plate coil and the rear plate coil can be achieved only by turning the needle in the opposite directions of the shaking table, and the front plate coil and the rear plate coil are not adhered to each other.

Step 2: knitting respective areas of the left sleeve, the right sleeve and the large body according to different yarn guides, and combining the sleeves and the large body to form by a needle reducing process above shoulder hanging;

as shown in fig. 8, the structure of the sleeve body integrated coil according to the present invention is shown.

Fig. 8 is a view of a sleeve body incorporating coil structure that is continuous with the shoulder insertion partial structure schematic shown in fig. 4.

The sleeve body combination is a key process of the sweater process and is completed through shoulder hanging and needle reducing. The left-right sleeve and large structure is formed by D, E, F areas, wherein the area D is provided with a yarn guide with the number 4 for weaving a left sleeve part, the area E is provided with a yarn guide with the number 3 for weaving a large part, and the area F is provided with a yarn guide with the number 5 for weaving a right sleeve part; 3, weaving the yarn carrier into each region of the body sleeve independently, wherein the regions are in an open state and are not connected.

and a2, when the knitting is carried out at the position of armpit shoulder hanging, the left sleeve and the right sleeve are combined with the middle large body, the yarn guide 4 in the D area of the left sleeve and the yarn guide 5 in the F area of the right sleeve quit knitting, meanwhile, the yarn guide 3 combines the loops in the D, E, F area by knitting, and the whole needles of the front and rear plate loops for hanging shoulder are reduced at the position of the E area of the large body according to the process requirements to form falling sleeve tissues b2, so that the purpose of meeting the process sizes of sleeve mountains and shoulder hanging curves is achieved, and the knitting and human body fitting of the sleeve body combined structure are completed.

As shown in fig. 9, it is a shoulder hanging and needle reducing design drawing of the present invention which is continuous with the sleeve body combined coil structure drawing.

After the sleeve body yarn guide is combined, knitting is performed by a needle reducing process according to the size requirements of the hanging shoulder and the sleeve top, and the knitting process is described by taking the left needle reducing action as an example.

The needle reducing action of the front and rear plate coils is respectively carried out by the empty needle position of the opposite needle plate. Firstly, knitting front and rear plate base tissue coils, then turning over the front plate needle reducing coils to the empty needle positions of the rear plate, moving the rear plate to the right for 2 needle positions, and turning over the rear plate coils to the front plate to finish the needle reducing action of the front plate coils; similarly, the needle of the rear plate needle reducing coil is turned over to the empty needle position of the front plate, after the rear plate moves 2 needle positions leftwards, the front plate coil is turned back to the rear plate, the needle reducing action of the rear plate coil is completed, falling and sleeving tissues of the front plate coil and the rear plate coil are formed respectively (shown in the X position in fig. 9), the needle plate moves 2 needle positions, and the front plate coil and the rear plate coil are reduced by 1 needle respectively (shown in the Y position in fig. 9).

And step 3: and stopping knitting at the front collar depth.

As shown in fig. 10, the front depth of cut rest knitting coil structure of the present invention is shown.

The needle selecting system special for the computerized flat knitting machine can select the function of each knitting needle in a targeted way, and can carry out knitting modes such as looping, tucking, non-knitting and the like on the same line at the same time.

The rest design is only for front plate coils (shown in the position O in fig. 10), the rear plate coils are normally woven, the front neck depth adopts a gradual rest weaving mode (shown in the position S in fig. 10) from the middle to two sides, the front neck depth coils are correspondingly reduced, the more the number of rest rows, the higher the neck depth size, and the lower the neck depth size otherwise; because the front plate coil is hung on the knitting needle and gradually retreats from knitting, the eyelet effect is formed, the appearance is influenced, and the tucking stitch with 1 needle at the edge is adopted to be hooked with the needle stopping coil to compensate the appearance effect caused by the eyelet (shown by the position T in figure 10).

After knitting is completed, the collar portion is knitted together with the front and rear panel stitches. The collar stop weaving sequence is as follows: the yarn guide is carried at the initial point to move from left to right, and a collar process with a front collar depth height and a high back and a low front can be woven according to the circulation direction according to the back plate coil → the front plate coil (right) → the back plate coil → the front plate coil (left), so that the collar process accords with the collar depth dimension.

Therefore, the weaving process of the full-formed raglan sleeve product is completed through the 4 steps.

According to the embodiment, the weaving realization of the forming process of the basic sweater can be met, the manufacturing of the fitting process of sewing-disc equipment such as fitting, sleeve feeding, collar feeding and the like of the traditional sweater is reduced on the basis of conforming to the basic wearing of the human body, the production efficiency is improved on the basis of not increasing the production cost and the added value, the design direction of the product process is changed, and the thinking and the help are provided for enterprises to develop the manufacturing of the full-formed products.

And can be suitably modified and implemented without departing from the gist of the present invention. The method is suitable for weaving the woolen knitted fabrics of other different types; the style structure is not limited to the implementation range listed in the invention, and the implementation changes of the conventional basic style such as seven-part sleeves, long sleeves and the like can be carried out; the weave structure is not limited to the direction and size of the skeins listed in the invention, and can also be realized by weaving mesh hollowing or other computer composite weave structures. In addition, the size of the needle hook is the main factor for hooking or holding the yarn,

the size of the needle hook is directly related to the style and needle type difference of the woven product. The weaving method is applied to product design, and can achieve better target effects in the aspects of reducing production cost, improving production efficiency and the like.

The terminology used herein is for the purpose of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
