Problems solved by technology

But this seaming method is only applicable to the situation that all weft yarns of a section are inserted at one time at the same time. If there are many layers of fabric, the weaving method must be divided into several times and the weft insertion can only be beaten up after the weft insertion reaches a full layer. None of the locking methods can meet the requirements
[0003] That is to say, when there are many layers of fabric, it is necessary to insert the weft layer by layer. The existing weft insertion adopts a single-side multi-layer weft insertion at the same time, and two wefts are inserted in one shed each time, and the weft yarn is not cut. For corner-linked or three-dimensional fabrics, after beating up, the selvedge on the weft inlet side forms a smooth edge, while the selvage edge on the weft exit side forms a ring-shaped burr. Since the weft yarn of the burr has no fixing effect on the warp yarn on the outermost side, the edge will appear. The phenomenon of edge collapse caused by the shedding of the warp yarns requires edge locking, but the existing edge locking methods cannot lock the edges of the weft-introduced fabric layer by layer

Embodiment 1

[0017] The technical scheme adopted in the present invention is: a sewing method for fast seaming, and the sewing method for fast seaming specifically includes the following steps:

[0018] 1). Rectangular circuit sewing: First place the multi-layer fabric that needs to be sewed flat, starting from the leftmost end of one side of the multi-layer fabric, the sewing needle passes through the fabric vertically to the other side of the fabric, and then to the right Translate the first fixed distance and then go back from the other side, and then translate the same distance to the right to pass through the multi-layer fabric, complete a cycle, and continue to each edge of the fabric, and perform a cycle after completing a fixed number of cycles The sewing thread is taut until after the initial starting point and knotted at the starting point;

[0019] 2). S-shaped sewing: start from the rightmost end of the single side of the fabric selected in step 1, the needle goes around the fi...

Abstract

The invention discloses a fast overlock sewing method. The fast overlock sewing method concretely includes the following steps of rectangular circuit sewing, S-shaped sewing, zigzag sewing and spiraloverlock, and the composite sewing and overlock method is adopted for fast sewing and overlock. The fast overlock sewing method includes the steps that fast sewing is conducted first so that differentcloth materials can be sewn together to form a flat and stable integrated cloth material, then the dual fast overlock mode is used to sew the edge of the integrated cloth material, the possibility that foreign matter is inserted into the seam of the integrated cloth material to cause damage to the integrated cloth material is eliminated, and meanwhile the possibility that the foreign matter enters the seam of the integrated cloth material is eliminated. The fast overlock sewing method has the firm overlock and fast sewing effects and is convenient, and sewn products are attractive and practical.

Description

technical field [0001] The invention relates to the technical field of sewing and seaming, in particular to a sewing method for fast seaming. Background technique [0002] The commonly used selvedge device of multi-layer fabric is to weave together selvedge yarn and ring-shaped rough edge weft yarn with crochet needle to reach the purpose of selvedge at present. But this seaming method is only applicable to the situation that all weft yarns of a section are inserted at one time at the same time. If there are many layers of fabric, the weaving method must be divided into several times and the weft insertion can only be beaten up after the weft insertion reaches a full layer. All the locking methods cannot meet the requirements. [0003] That is to say, when there are many layers of fabric, it is necessary to insert the weft layer by layer. The existing weft insertion adopts a single-side multi-layer weft insertion at the same time, and two wefts are inserted in one shed each...
