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, which have a longer service life and higher fishing efficiency. Fishing nets made of nylon 6 are used more and more. According to market demand, different dyeing treatments are required for nylon 6 fishing nets to improve its performance. However, the existing nylon 6 fishing net dyeing process has a low dyeing percentage for nylon 6 fishing nets, and the entire dyeing process lasts for a long time. prone to unevenness
[0003] The half-dyeing time is the time required to achieve half of the equilibrium adsorption amount of the dye on the nylon 6 fishing net. The half-dyeing time is a very important performance index for dyeing the nylon 6 fishing net. The shorter the half-dyeing time, the faster the dyeing rate. , but the half-dyeing time of nylon 6 fishing nets treated by the existing dyeing process is longer

Embodiment 1

[0018] A nylon 6 fishing net dyeing process, comprising the following steps:

[0019] (1) Pretreatment: Pretreatment of nylon 6 fishing net: soak the nylon 6 fishing net in the pretreatment solution, the quality of nylon 6 and the pretreatment solution is 1:12, soak in a 45°C water bath for 10 minutes, and then soak in a water bath. Heat up at a heating rate of 0.5°C / min. When the temperature rises to 88°C, keep it at this temperature for 35min, then use 450W ultrasonic treatment for 2min, and then cool down the water bath at a rate of 1°C / min. When the temperature drops to 50°C From time to time, continue to keep the temperature for 20 minutes, take out the nylon 6 fishing net, soak the nylon 6 fishing net in 50 °C water for 10 minutes, and after taking it out, dry it in a vacuum at 50 °C to constant weight;

[0020] The pretreatment solution is made of the following components by weight: 2.3 of urea, 1.3 of sodium phosphate, 0.4 of sodium dodecylbenzenesulfonate, 0.2 of hydr...

Abstract

The invention discloses a nylon 6 fishing net dyeing process. The nylon 6 fishing net dyeing process comprises the following steps: (1) preprocessing, (2) dyeing and (3) color fixing. The problems of uneven dyeing, flower dyeing, aberration and color defect which are easily caused in dyeing of nylon 6 fishing nets can be solved. The utilization rate of dyestuff and the color fastness are improved, dyeing processing risks are reduced, the semi-dyeing time of the dyestuff can be greatly reduced, the dyeing speed is increased, a certain amount of cactus extracting solution is added during dyeing, a dye liquor treatment environment is gentle, damage to the nylon 6 fishing net is small, the use performance of the nylon 6 fishing net is not affected, and meanwhile, the dyeing speed is not reduced.

Description

technical field [0001] The invention belongs to the technical field of fishing net dyeing, and particularly relates to a nylon 6 fishing net dyeing process. Background technique [0002] Fishing nets are nets for fishing. Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials, which have a longer service life and higher fishing efficiency. Fishing nets made of nylon 6 are used more and more. According to market demand, nylon 6 fishing net needs to be dyed differently to improve its performance, but the existing nylon 6 fishing net dyeing process has a low percentage of dyeing on nylon 6 fishing net, and the entire dyeing process lasts for a long time. It is easy to appear uneven phenomenon. [0003] The half-dye time is the time required for the dye to reach half of the equilibrium adsorption capacity of nylon 6 fishing nets. The half-dye time is a very important performance index for dyeing nylon 6 fishing nets. The shorter the half-dye t...
