Problems solved by technology

However, when the existing fishing nets are dyed, the dyeing efficiency of the fishing nets is low, the entire dyeing process lasts for a long time, the color fastness is low, and the color is easy to fade, especially the working environment of the fishing nets is not only a freshwater environment but also a seawater environment, and the working time is longer , long-term immersion in fresh water or sea water can easily cause a large number of fishing nets to fade

Embodiment 1

[0015] A high-efficiency dyeing process for fishing nets, comprising the following steps:

[0016] (1) Comb the fishing nets, organize them into bundles every 3kg, and soak them in warm water at a temperature of 40°C for 30 minutes. Then heat up to 80°C, use 35kHz ultrasonic treatment for 30min, then take it out and put it in ice water, 25kHz ultrasonic treatment for 10min, take it out, put it in ethanol solution, soak for 1h, take it out and dry it;

[0017] (2) Put the fishing net obtained in step (1) into the dyeing auxiliaries, take it out after ultrasonic treatment at 50kHz for 10 minutes, vacuum-dry it at 40°C, and then carry out microwave irradiation treatment. The treatment conditions are: the power is 15KW, and the microwave irradiation time is 40s.

[0018] (3) Put the fishing net obtained in step (2) into a vacuum pressure treatment tank, add dyeing agent, stir for 2 minutes, heat the dyeing solution to 50°C, evacuate to a vacuum degree of 0.06MPa, and maintain it ...

Abstract

The invention discloses an efficient fish net dyeing technology. The technology is simple, convenient to implement, uniform in dyeing, efficient in coloring and high in drying firmness; a fish net iscarded into bundles, then, gradient heating ultrasound and cold water ultrasound operations are performed, internal fiber inside the fish net is preliminarily softened, the tenacity of the fish net isenhanced, and preparation is made for follow-up uniform dyeing; dyeing auxiliaries are used for processing the fish net, microwave radiation is performed, water inside the fiber of the fish net in ahigh-strength microwave field is rapidly heated and vaporized, the fiber ventilation rate is increased, and therefore a novel fluid channel is formed, and the internal surface area of the fish net isincreased; accordingly, the dyeing auxiliaries can be rapidly soaked into the fish net; due to the effect of the dyeing auxiliaries, bacteria are killed, the original color of the fish net is removed,and the fish net dyeing efficiency and color saturation are improved.

Description

technical field [0001] The invention belongs to the technical field of fishing net dyeing, and in particular relates to a high-efficiency dyeing process for fishing nets. Background technique [0002] Fishing net is an indispensable production tool in aquaculture and fishing. According to market demand, different dyeing treatments are required for fishing nets to improve its performance. Whether the dyeing technology is appropriate or not is directly related to the service life and production cost of fishing nets, especially Today, when the price of feed continues to rise and the economic benefits of fishery are generally low, it has more practical significance for farmers to reduce expenditure and increase income. However, when the existing fishing nets are dyed, the dyeing efficiency of the fishing nets is low, the entire dyeing process lasts for a long time, the color fastness is low, and the color is easy to fade, especially the working environment of the fishing nets is...
