Special fishing net weaving forming process and special fishing net

Abstract

The invention relates to a weaving forming process for a special fishing net. Weaving of the special fishing net is completed through a single warp knitting machine. In actual weaving, a plurality of side-by-side and diameter-arranged line chaining weaves are connected into a whole through the weft groups, and the side guide position of each weft group can be adjusted according to a specific weaving process, so that the warp winding mode of the weft groups on a weaving knot is changed. Thus, on one hand, the purchase cost of required equipment is greatly reduced, and the occupied area of a site is also reduced; (2) the woven special fishing net has higher tensile strength, the manufacturing and forming quality is easy to control, and the yield is extremely high; the size and the distribution form of meshes of the special fishing net are easy to adjust in the warp knitting process, and a single warp knitting machine has the capacity of producing the special fishing nets of various specifications at the same time. In addition, the invention further discloses the special fishing net formed through the knitting forming technology.

Description

technical field [0001] The invention relates to the technical field of special fishing net weaving, in particular to a special fishing net weaving molding process and a special fishing net. Background technique [0002] Under the background of my country's vigorous development of deep-sea aquaculture and deep-sea fishing, fishing nets have been widely used, and according to different operating environments, there are special requirements for the specifications of fishing nets. For example, in some rare species gathering areas, special fishing nets are required (the mesh size gradually decreases with the increase of water depth), so as to achieve hierarchical and targeted fishing. In the prior art, the forming process of special fishing nets is roughly as follows: first, different types of warp knitting machines are used to form a variety of fishing nets with different mesh sizes, and then manual sewing is required to stitch different nets together. Purpose The fishing nets ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned technical scheme can be used to form special fishing nets, however, its manufacturing cost is extremely high and the forming efficiency is low, which is specifically reflected in the following: in the initial manufacturing stage, multiple warp knitting machines of different types are required to participate, which not only increases the layout The site is difficult, and it also increases the cost of equipment procurement

Moreover, the fishing net needs to be docked and stitched after it is initially manufactured, which will inevitably involve a lot of manpower and material resources, thereby further increasing the manufacturing cost of the special fishing net and the total input man-hours.

In addition, the final molding quality of special fishing nets (mainly reflected in the tensile strength) has a strong correlation with the quality of sewing personnel and sewing techniques, resulting in a high rate of defective products
