Problems solved by technology

[0004] In order to overcome the shortcomings of the existing nylon fishing nets that are easily shaped by high-temperature steam, the chemical structure of the nylon is unstable, the nodules are not fixed firmly, and the continuous production cannot be carried out. Method for setting the shape of a nylon fishing net sheet that is not deformed and can be continuously stretched and shaped

Embodiment Construction

[0027] A method for setting the shape of a nylon fishing net sheet, which undergoes the following process steps:

[0028] a. Consolidation treatment

[0029] Inject the consolidation solution into the FRP immersion tank of length×width×depth=5.80m×0.25m×0.35m. The consolidation solution is a water-based acrylic resin solution with a concentration of 20% to 40%, and the liquid level is slightly higher than The stacking height of the mesh shall prevail; the FRP soaking tank is placed under the weaving machine, and the nylon fishing nets woven by the weaving machine are directly sent to the FRP soaking tank for stacking and soaking treatment for 5-10 minutes; After the sheet is processed, it can improve the anti-slip resistance of the mesh nodules, enhance the firmness of the nodules, reduce the internal stress at the bend of the mesh knot, and increase the tensile strength of the mesh. It should be pointed out that the soaking time of the mesh can be determined according to the...

Abstract

The invention discloses a method for shaping nylon fishing net mesh, which is to solve the problem that the chemical structure of the nylon is unstable due to the presence of high-temperature steam shaping, and the tubercle shape is not stable and cannot be produced continuously. The invention relates to a knot of a nylon fishing net mesh, which is woven from a web-weaving machine, and is introduced into a pre-rolling machine, and then introduced into a pre-rolling machine to carry out one-time rolling and leveling process. Then, the first drying box, the second drying box, the heating and drying processing and the traction stretching and fixing processing of the first drying box and the second drying box are respectively guided through different predetermined temperatures, and after the heating and drying treatment, the mesh is re-introduced into the rear rolling mill to be rolled and leveled, and finally, dried in the air-drying field, cooled naturally at normal temperature, and contracted and fixed. The invention relates to a shaping method of the nylon fishing net mesh, which has the advantages of reasonable process, strong operability and easy realization of continuous production. The profiled nylon fishing net has stable structure, stable tubercle shape, no deformation and good appearance effect.

Description

technical field [0001] The invention relates to heating or cooling shaping of fabrics, in particular to a shaping method for nylon fishing net sheets. Background technique [0002] We know that nylon is the Chinese name of synthetic fiber nylon, and its chemical name is polyamide fiber, which has the following characteristics: low density, high strength, good wear resistance, high elasticity, large elongation, and good resistance to multiple deformations , which is a good material for making fishing nets; but because of its high elasticity and elongation, it is not easy to maintain the firmness of the net knot, has low moisture absorption, poor light resistance, and can withstand high heat in a short period of time, but its strength will decrease after being heated for a long time Reduced, good dyeing performance. In view of the characteristics of nylon fiber, after the nylon fishing net mesh is woven from the net weaving machine, the firmness of the net knot is not enough ...
