It is not intended to represent all of the technical spirit of the present application, and it should be understood that there may be various equivalents and modifications that may substitute them at the time of the present application.

The first technical idea presented here is that the binding net has a high strength and provides flexibility for the operator to work easily, and also can provide the ease of subsequent processing by inducing the generation of static electricity when cutting and cutting the binding net. In order to provide the binding net of the optimum conditions by adjusting the synthetic resin raw material mixing ratio, in the present application, when the binding net 30 is manufactured, the binding net 30 is obtained using the raw material yarn 20 mixed with three kinds of materials. As described above, three types of raw materials are used, and high density polyethylene (HDPE), polypropylene (PP, polypropylene), and linear low density polyethylene (LLDPE) are used. It was intended to use a raw material yarn 20 provided with 80 ± 10w%, polypropylene 15 ± 7w%, and linear low density polyethylene 5 ± 3w%. As the HDPE is said to have less side chaine in the polymer, the smaller the side chains, the better the stacking and the higher density, and the higher density provides the raw material with higher strength. Methyl group (CH ₃ ) is attached to every carbon of carbon, and has a regular form with a short branch. The LLDPE has many side branches like LDPE (Low Density Polyethylene), but its overall structure is linear. Lower than HDPE and higher than LDPE.

Therefore, in the present application, a high-density polyethylene with high density and high strength is added to a polypropylene that is flexible and tensioned to generate static electricity at the cutting part when cutting, and has a relatively low strength but high flexibility compared to a high density polyethylene. It was attempted to use as a raw material yarn 20 by mixing low-density polyethylene, for example, when obtaining a binding net using the weaving machine of the present application, the raw material yarn 20 mixed with three kinds of synthetic resin raw materials is used, The weft yarn may simply use the raw material yarn 10 made of high density polyethylene, or the raw material yarn 10 'made by mixing only the high density polyethylene and polypropylene may be used.

The binding net 30 is woven using the raw material yarn 20 provided in the above three raw material blending composition ratio of the company to confirm that the weight can be provided to increase the workability by increasing the flexibility As a completed invention, for example, the mixing ratio of high density polyethylene (HDPE), polypropylene (PP) and low density polyethylene (LLDPE) is in the range of HDPE 80 ± 10w%, PP 15 ± 7w%, LLDPE 5 ± 3w% Naturally, even if it is out of the way, it can be used as a raw material for the binding net. However, as the applicant desires, the binding net has high strength and at the same time maintains flexibility, and induces proper static electricity when cutting and cutting the binding net, so that It only results in slightly less than the effect of providing ease, and does not interfere with the normal binding net.
