Description

A kind of seamless knitted trousers and a weaving process of seamless knitted trousers

technical field

The invention relates to the technical field of garment engineering and manufacturing, in particular to a seamless knitted trousers and a weaving process of the seamless knitted trousers.

Background technique

Although the seamless knitted trousers in the prior art are called "seamless" knitted trousers, the inner seam and the crotch need to be spliced and stitched, and at least one or two of the following stitching methods must be used to meet the needs of the human body. Formal needs and mobility needs of the legs, crotch and crotch:

One kind of sewing method is to cut the seamless knitted circular fabric piece along the crotch seam and the inner seam, and then sew along the inner seam of the trouser leg through the bottom crotch to the inner seam of the other trouser leg to form a coherent inner seam line. The specific structure Please refer to Figures 1 and 2, the crotch seam and the inner seam form the inner seam line 1 shown in the figure. It is relatively simple to use this method to join the crotch seam and the inner seam of the trousers, but usually the crotch margin is insufficient, which affects the movement, makes it uncomfortable to wear, and the excess fabric cut off will cause waste of raw materials.

For another suture method, please refer to Figure 3. Put together an oval or other suitable shape of homogeneous or heterogeneous fabric at the bottom of the crotch as the crotch clamping fabric 2, or directly break the inner suture line 1, and clamp the crotch. The cloth piece 2 is embedded in the bottom crotch position, and then it is stitched together with the two trouser legs or the disassembled inner seam line 1 . This method adds more margin to the bottom crotch, and is more comfortable to wear than the first method, but it increases stitches, and the man-hours and costs of the process are also significantly increased.

Although the above two methods are not the same, the bottom crotch of knitted pants needs to be sewn, and the finished pants all have inner seams and bottom crotch seams. For people who are exercising and walking, especially for people with fat inner thighs, when wearing tight-fitting bottoms, the existence of inner seams and bottom crotch seams will cause greater friction, especially in summer sweating Frequent itching and discomfort.

In this regard, in order to meet the comfort requirements of the human body for knitted trousers, the size requirements of the trousers are generally met by adjusting the position of the inner seam, such as moving the inner seam and bottom crotch seam forward or backward from the original position to reduce friction; Or meet the leg circumference requirements and meet the activity needs of the crotch and the bottom crotch by increasing the cutting and joining methods such as the bottom crotch triangle.

The tuck structure of the first fabric block 16 increases the pressure support effect of the abdomen, and the part extending to the back body 12 of the trousers can also increase the stretch fastness here, and simultaneously increase the depth of the crotch.

For the seamless knitted trousers described above, the present invention also discloses a weaving process for seamless knitted trousers, which includes the following steps:

Step 1: use a computerized circular machine to weave a tubular fabric (as shown in Figure 4-1 and Figure 4-2), the tubular fabric includes trouser legs 13, crotch and trouser body fabric parts that are integrally formed and woven together, The trouser body fabric part comprises support belt 20, hip fabric region 18, buttocks fabric block 17 and first fabric block 16, and hip fabric region 18 and buttocks fabric block 17 correspond to human hip and human buttocks position respectively , the support belt 20 is located between the trouser leg 13 and the buttocks fabric block 17, a part of the first fabric block 16 corresponds to the position of the abdomen of the human body to support the abdomen, and the other part extends to the back body of the trousers 12 and is located between the two buttocks fabric blocks 17 , with the center of the hip fabric area 18 as a reference point, the tubular fabric is flattened to form a double-layer structure, and a mark of a preset length is woven at the position of the symmetrical centerline of the tubular fabric on the first fabric block 16 Line 161 (during specific implementation, the preset length is 10-12 cm, but not limited thereto, the length of this marking line can be increased or decreased according to the needs of the waist circumference);

Step 2: Cut along the marking line 161 to form an opening. Due to the interaction of the stretching and recovery of different parts of the tubular fabric, the trousers 13 are automatically retracted inward at this time, and the opening is further opened (this opening will be opened during specific implementation). about 20-24 cm in length, preferably 24 cm);

Step 3: Seam the waist 21 in alignment with the opening to form the trouser waist. Please refer to the suture line 22 shown in Figure 6-1 for the details of the sewing position, and finally form the trousers as shown in Figure 6-1 and Figure 6-2 No inner suture line, no crotch seam, seamless knitted trousers that fit close to the body, wherein the waistband 21 preferably adopts a double-ribbed belt fabric with a width of 3 cm and a circumference of 48 cm.

When implementing the above-mentioned weaving process, apply the SantoniSM8-Top2 computer circular machine (the diameter of this circular machine is 13 inches, the machine number is E28, has 8 knitting systems, a total of 1152 pieces of knitting needles), the application of polyurethane fiber (linear density 44 denier , specification 44/34F) and polyamide covered yarn (linear density 40 denier, specification 40/20) for weaving seamless knitted pants.
