The pH of suspension is adjusted to 3.5,78 DEG C are heated to, after 120r/min rotating speeds stirring 30min, then suspension quality is added
0.16% ammonium persulfate, after stirring, 18min is incubated at 60 DEG C, using 350W ultrasonication 3min, is then carried out
Vacuum filtration, is dried using vacuum drying chamber at 100 DEG C, produced.
Further, it is described that the master batch of nylon 6 is mixed and made into fishing net with activation nano diatomite, it is specially that nylon 6 is female
Grain presses 100 with activation nano diatomite：Melting extrusion in an extruder after 3.2-3.5 mass ratio is uniformly mixed, through supercooling
But preliminary draft, drafting forming, winding, line processed, then carry out knitmesh, are made fishing net.
Further, the fishing net with good dyeability is dyed using acid dyes, in dyeing, oxytropism
Acid dyes quality 1.2-1.6% rare earth oxide is added in dyestuff, is stirred, you can.
Further, described when the fishing net with good dyeability is dyed using acid dyes, bath raio is 1：
30, dyeing condition is：50 DEG C enter dye, and 1 DEG C of heating per minute, to 88 DEG C of stoppings, being incubated 15min, is then cooled to 50 DEG C
Fishing net surface loose colour 5min is cleaned, is dried at 80 DEG C to constant weight, you can.
Further, the rare earth oxide is lanthana.
The present invention has advantages below compared with prior art：The present invention can solve fishing net dyeing and easily uneven dyeing occurs,
The problem of dyeing flower, aberration, color defect, dye utilization rate and dyefastness are improved, dyeing process risk is reduced, by being prepared in fishing net
Middle a certain amount of activation nano diatomite of addition passes through with adding a certain amount of rare earth oxide in dyestuff when fishing net is dyed
Rare earth oxide is had an effect with dye molecule group, and the dye groups having an effect are carried out with activation nano diatomite again
Effectively combine, what dyestuff can be more prone to enters inside fishing net, and adhesion is improved significantly, therefore, it is possible to significantly carry
High dyeing rate and dyefastness.
