Fig. 1 and 2 show a schematic structure diagram of a special fishing net and an I partial enlarged view thereof, and it is known that the special fishing net is composed of a warp knitting chain structure 1 and a weft knitting chain structure 2. Wherein, the warp knitting chain structure 1 is composed of a plurality of warps 11 which are flattened along the width direction of the special fishing net. A plurality of woven knots 111 are formed in each warp yarn 11 and are uniformly distributed along the length direction thereof. The weft knitting structure 2 is used to join the warp knitting structures 1 together, and is constituted by at least two weft yarns 21 starting from the warp yarn 11 at the knitting initiation point. The weft threads 21 are simultaneously wound and divided into the knitting knots 111 on the different warp thread knitting structures 1, and a plurality of connecting areas 3 which are formed by the side guidance and interlacing of the weft threads 21 and are distributed along the length direction of the special fishing net are additionally formed between the two adjacent warp thread knitting structures 1. The distribution density of the connecting area 3 directly determines the size of the special fishing net meshes, and the size and the distribution form of the special fishing net meshes are easy to adjust in the warp knitting process, so that the special fishing net meshes meet the requirements of different fishing operation environments.
It should be noted that, according to different customer requirements, the forming process of the special fishing net is also different, for example, the first weft may be preferably formed by yarn bundles or twisted by a plurality of yarns.
Furthermore, as can be clearly seen from the figures 1 and 2, the special fishing net formed by knitting is of an integrated structure, does not contain any splice, has higher tensile strength and is beneficial to prolonging the service life.
Further, as shown in fig. 2, the weft knitting structure 2 is constituted by two weft yarns 21 whose initial points start from the first warp knitting structure 1. Therefore, the formed special fishing net can be effectively ensured to have extremely strong tensile strength and ductility.
Finally, it should be noted that, in view of ensuring that the special fishing net has a reasonable mesh size and the actual production difficulty of the comprehensive warp knitting machine, the distribution form of the linking area 3 needs to be controlled, and the extension length of the single linking area 3 is equal to or greater than 3d assuming that the distance between two adjacent knitting knots on the same warp knitting chain structure 1 is d.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
