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, nylon 6 fishing nets have excellent coloring performance, especially high dyeing speed, but when dyeing nylon 6 fishing nets, the dyeing speed is slow, the color fastness is low, and the color is easy to fade

Embodiment 1

[0014] A nylon 6 fishing net with high dyeing rate, which is uniformly mixed with modified nylon 6 98, polyester 6, plasticizer 1.4, and nano-bentonite 0.3 in parts by weight, then melted and extruded by an extruder, cooled and pre-drawn , drafting and setting, winding, thread making, and net weaving to obtain nylon 6 fishing nets;

[0015] The preparation method of the modified nylon 6 is as follows: adding 1,4 polybutadiene liquid rubber, maleic anhydride, and xylene to the stirrer, heating in a water bath to 78°C, stirring at a speed of 200r / min for 25min, and then gradually The benzoyl peroxide solution was added dropwise, and the dropwise addition was completed within 20-22 minutes. The total mass of the benzoyl peroxide solution added dropwise was 10% of the mass of the 1,4 polybutadiene liquid rubber, and the temperature was adjusted to 88°C. Stir at a speed of 120r / min for 2 hours to obtain a mixed reaction solution. Add methanol with 80% xylene mass to the mixed react...

Abstract

The invention discloses a high-dyeing rate nylon 6 fishing net. The high-dyeing rate nylon 6 fishing net is obtained by uniformly mixing modified nylon 6, polyester, a plasticizer and nano-sized bentonite, then performing melt extrusion by using an extruder, cooling and pre-drafting, drafting and shaping, winding, making wires and netting. Through modification of the nylon 6, the internal structure of the nylon 6 can be greatly improved, the crystallinity of the nylon 6 is reduced, and the internal molecular structure of the nylon 6 is loosened to a certain extent to increase internal pores of the nylon 6 and reduce the hydrophobicity, so that in the dying process after the nylon 6 is produced into the fishing net, dye molecules can continue to quickly diffuse or penetrate into crystal areas after the dye molecules diffuse or penetrate into molecular amorphous areas, and the dyeing rate and the dyeing fastness of the nylon 6 fishing net can be greatly improved; through modification of the nylon 6, the monofilament tensile strength of the nylon 6 fishing net can be significantly improved, so that the using performance of the nylon 6 fishing net is improved.
