Problems solved by technology

[0002] Fishing net is a net for fishing. Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials. They have a longer service life and higher fishing efficiency. Fishing nets made of nylon or polyethylene are more and more used. Many, according to market demand, different dyeing treatments are required for fishing nets to improve their performance. However, when the existing fishing nets are dyed, the dyeing rate of fishing nets is low, the entire dyeing process lasts for a long time, and the color fastness is low. It is easy to fade, especially the working environment of fishing nets is not only fresh water environment but also sea water environment. The working time is long, and long-term immersion in fresh water or sea water can easily cause a large number of fishing nets to fade

Embodiment 1

[0018] A photografting modification treatment process for the surface of nylon fishing nets. The photoinitiator and grafting monomer are mixed and dissolved in an organic solvent to make a grafting solution, and then the grafting solution is added to the reaction kettle, and then the temperature is kept at 55°C. Nitrogen gas is then introduced into the grafting liquid to remove oxygen in the grafting liquid. The nitrogen gas feeding time is not less than 30 minutes, and the nylon fishing net is modified with a monofunctional compound, and then the modified nylon fishing net is soaked at a ratio of 150g: 350mL until the graft solution, and then uniformly irradiated with ultraviolet light to generate grafting reaction, the grafting reaction time is 40min, take it out after the reaction, then add it to a sodium carbonate solution with a mass fraction of 5% and soak for 10min, and then take it out, using a mass fraction of 5% Soak in citric acid solution for 10 minutes, then take i...

Embodiment 2

[0029] A process for photografting modification of the surface of nylon fishing nets. The photoinitiator and grafting monomer are mixed and dissolved in an organic solvent to make a grafting solution, and then the grafting solution is added to the reaction kettle, and then the temperature is kept at 60°C. Nitrogen gas is then introduced into the grafting solution to remove oxygen in the grafting solution. The nitrogen gas feeding time is not less than 30 minutes, and the nylon fishing net is modified with a monofunctional compound, and then the modified nylon fishing net is soaked at a ratio of 160g: 350mL until the graft solution, and then carry out the uniform irradiation of ultraviolet light to generate grafting reaction, the grafting reaction time is 50min, take it out after the reaction, then add it to the sodium carbonate solution with a mass fraction of 5% and soak for 15min, then take it out, using a mass fraction of 5% Soak in citric acid solution for 15 minutes, then ...

Embodiment 3

[0040] A process for photografting modification of the surface of nylon fishing nets. The photoinitiator and grafting monomer are mixed and dissolved in an organic solvent to make a grafting solution, and then the grafting solution is added to the reaction kettle, and then the temperature is kept at 58°C. Nitrogen gas is then introduced into the grafting solution to remove oxygen in the grafting solution. The nitrogen gas feeding time is not less than 30 minutes, and the nylon fishing net is modified with a monofunctional compound, and then the modified nylon fishing net is soaked at a ratio of 155g: 350mL until the graft solution, and then carry out the uniform irradiation of ultraviolet light to generate grafting reaction. The grafting reaction time is 46min. After the reaction, take it out, then add it to the sodium carbonate solution with a mass fraction of 5% and soak for 12min, and then take it out. The mass fraction is 5% Soak in citric acid solution for 12 minutes, then...

Abstract

The invention discloses a surface optical grafted modification treatment process for a nylon fishing net. According to the invention, a grafting solution is added in a reaction vessel, and then is kept under constant temperature, nitrogen is introduced in grafting liquid to eliminate oxygen in the grafting solution, a monofunctional compound modified nylon fishing net is employed, and is then is immersed in the grafting solution, ultraviolet light uniform irradiation is carried out to generate a grafting reaction, after the reaction, the material is taken out, then is added to a sodium carbonate solution for immersion, and is taken out, the material is immersed by employing a citric acid solution, then is taken out, is flushed by employing deionized water, and is naturally drained to obtain the product. Through the surface optical grafted modification treatment process, and the adsorption performance of the nylon surface on dyed molecules through a grafting method.
