[0030] The machine head moves from the right side to the left side. Left-purl the 21st stitch by one stitch;

[0031] So far, one purl and increase cycle ends;

[0032] The arc edge knitting means knitting four stitches on each side and knitting in a cycle until the set width;

[0033] The cycle knitting of the middle part is as follows:

[0034] Use the No. 5 yarn nozzle for knitting. Knit 5 stitches on the front needle bed from the 17th to the 21st stitch from left to right; Knit 1 stitch on the 21st back needle bed; Knit from the 21st to the 487th stitch on the front needle bed; Knit 1 stitch on the 487th back needle bed; Knit from the 487th to the 491st stitch on the front needle bed, knit from the 490th to the 486th stitch on the back needle bed, knit 1 stitch on the 486th front needle bed, and the machine head returns to the left side;

[0048] The production process includes collar surface knitting, collar seat knitting and double-sided knitted collar finishing process. This embodiment is described with size M, which has 495 needles.

[0049] The collar surface knitting includes: using parallel braided yarn and spandex filament at the start, and the No. 2 yarn mouth stops at the left side; then the No. 3 yarn mouth and the No. 5 yarn mouth are synchronously knitted according to the air layer structure and connected by the No. 4 yarn mouth tuck, and the collar surface is synchronously knitted through the front and rear needle beds; and the back side of the air layer part formed is tighter than the front yarn tension. Specifically in this embodiment, the back yarn tension is 8% greater than the front yarn tension. The two ends of the edge of the collar seat are close to the collar surface and are arc-shaped, and are knitted by adding needles.

[0050] The collar knitting includes the following steps in sequence:

[0051] At the starting point, the No. 8 yarn mouth clamps the yarn on the 1*1 front and rear needle beds to knit 4 rows without connection with staggered needles. The No. 8 yarn mouth is withdrawn from the yarn mouth position, and the knitting needles on the rear needle bed are transferred to the front needle bed.

[0052] The first yarn guide withdraws the yarn and knits 2 rows on the front needle bed, then the first yarn guide returns to the yarn guide position.

[0053] The second yarn guide starts knitting 3 rows, and the rest of the yarn guides do not knit and idle.

[0054] In the 10th row, 12th row, and 14th row, the third yarn guide and the fifth yarn guide knit from left to right on the front and back needle beds, and the last stitch is not knitted but left as an empty stitch.

[0055] In the 11th row, 13th row, and 15th row, the second yarn guide, the third yarn guide, and the fifth yarn guide start knitting on the front needle bed from the first stitch on the right side. After knitting, the second yarn guide returns to the yarn adding position.

[0056] After the cylinder rotates 2.5 turns, one empty stitch is left for the last stitch.

[0057] From the 16th row, the third yarn guide, the fifth yarn guide, and the fourth yarn guide perform double-sided air layer knitting. Among them, the third yarn guide and the fifth yarn guide form the front and back sides, and are connected by the fourth yarn guide's group of dropped stitches; and the tension of the yarn on the back side is greater than that of the yarn on the front side.

[0058] According to the required knitting width, the yarn guides return to the yarn guide position.

[0059] So far, the collar surface knitting is completed.

[0060] The collar base knitting sequentially includes the following: purl stitch and increase stitch cycle, arc edge knitting, middle part cycle knitting, and bottom knitting.

[0061] The purl stitch and increase stitch cycle is as follows:

[0062] The machine head returns to the right side and moves to the left side, turns the 489th stitch to the back needle bed, turns the 19th stitch on the left side one stitch to the left and then turns it over, then turns the 18th stitch on the left side to the front needle bed, turns the 19th stitch on the left side to the front needle bed, and the middle part is not knitted.

[0063] The machine head moves from the left side to the right side, turns the 488th stitch to the back needle bed, turns the 489th stitch to the back needle bed; the middle part is not knitted.

[0064] The machine head moves from the right side to the left side, moves the 19th stitch on the left side one stitch to the left, turns the 20th stitch on the left side one stitch to the left and then turns it over, turns the 19th stitch on the left side to the front needle bed, turns the 20th stitch on the left side to the back and front needle beds, and the middle part is not knitted.

[0065] The machine head moves from the left side to the right side, turns the 487th stitch one stitch to the right, turns the 488th stitch one stitch to the right; turns the 487th stitch to the front and back needle beds, turns the 488th stitch to the back needle bed, and the middle part is not knitted.

[0066] The machine head moves from the right side to the left side, moves the 20th needle on the left side one needle to the left, turns the 21st needle on the left side one needle to the left, turns the 20th needle on the left side to the front needle bed, turns the 21st needle on the left side to the back needle bed, and does not knit the middle part.

[0067] The machine head moves from the left side to the right side, turns the 486th needle one needle to the right, turns the 487th needle one needle to the right; turns the 486th needle to the front and back needle beds, turns the 487th needle to the back needle bed, and does not knit the middle part.

[0068] The machine head moves from the right side to the left side, turns the 21st needle one needle to the left.

[0069] Thus, one loop of turning and adding needles is completed.

[0070] The so-called arc-edge knitting means knitting four needles on each side, knitting in a cycle until the set width, specifically through 11 cycles of knitting.

[0071] The middle part is knitted in a cycle as follows:

[0072] Use the No. 5 yarn nozzle for knitting. Knit 5 needles on the front needle bed from the 17th to the 21st needle from left to right; knit 1 needle on the 21st back needle bed; knit from the 21st needle to the 487th needle on the front needle bed; knit 1 needle on the 487th back needle bed; knit from the 487th needle to the 491st needle on the front needle bed, knit from the 490th needle to the 486th needle on the back needle bed, knit 1 needle on the 486th front needle bed, and the machine head returns to the left side.

[0073] Knit 1 needle on the 22nd front needle bed; knit from the 22nd needle to the 18th needle on the back needle bed.

[0074] Until one cycle ends and repeat several cycles, specifically 17 cycles. Then knit one row according to the air layer with the No. 5 yarn nozzle and the No. 4 yarn distance; thus, an arc appears on the collar stand.

[0075] The so-called bottom knitting means that after an arc appears on the collar stand, then use the No. 5 yarn nozzle and the No. 4 yarn distance to knit according to the air layer to the set width, then do 1*1 front and back needle bed misaligned needle knitting for 2 rows; and do 14 rows of idling, 12 rows of waste yarn idling, and turn single-sided knitting for 1 row.

[0076] The post-treatment process includes mercerization and shaping.

[0077] The mercerization treatment is to use a mercerizing machine to conduct mercerization treatment on the prepared double-sided knitted collar. It is to put several prepared garment pieces into the mercerizing machine after stepping on the yarn to seal, place them in the treatment liquid, soak statically for 5 minutes, then stir at a speed of 15 - 16 r / min for 20 - 30 minutes; take them out and dehydrate, then place them in a dryer for drying. The water content in the dehydrated garment pieces does not exceed 25% and is not less than 15%, and it should not be too dry, otherwise "chicken claw marks" defects will appear.

[0078] During the fabric weaving process, thermoplastic spandex is embedded, so the known shrinkage rate is used for plate making during weaving. The drying temperature is between 55 and 68 degrees Celsius. The woven piece is slightly wider than the required size by about 0.5 - 1 cm. Open the oven and blow cold air for 5 minutes to allow it to cool sufficiently. Take it out and place it on the table, and stack it neatly by hand. Stacking neatly is not easy to cause pleat marks.

[0079] For the woven pieces containing wool and spun silk cotton components, the cold air should be started first and dried for about 15 minutes to allow the pleat marks caused by excessive dehydration or extrusion during the dehydration process to fully expand, and then the air is started for the next drying step.

[0080] The sizing is to heat the pressing machine to 130 - 140 °C. If it is too high, laser marks are likely to appear; if it is too low, the retraction size is difficult to be standard. Feed the double-sided knitted collar in, with its back facing the side that is being heated, making it in an inwardly buckled shape; and measure the size to ensure that the tolerance does not exceed 0.3 cm.

[0081] After post-treatment sizing, the collar is straight and has a soft touch. Even if it is grabbed and rubbed destructively and then released, it will immediately return to its original shape. It will not deform or warp after being machine-washed more than 50 times.

[0082] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
