Description
Technical field
The invention belongs to fishing net staining technique field, and in particular to a kind of fishing net dyeing.
Background technology
Fishing net is the net of fishing, and modern fishing net mainly uses the raw material such as polyethylene, nylon to be processed, and has longer make
With cycle, and higher catching rate, applied using nylon or polyethylene as fishing net prepared by material it is more and more, according to market
Demand, need to carry out different dyeing to fishing net and handle, improve its performance, but when existing fishing net dyes, to fishing
The dyeing rate of net is relatively low, and whole dyeing course duration length, dyefastness is low, fugitive color, especially the building ring of fishing net
Border is not only that fresh water environment also has briny environment, and the working time is longer, and long period of soaking easily causes fishing in fresh water or seawater
Net is a large amount of to fade.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of fishing net dyeing.
The present invention is achieved by the following technical solutions：
A kind of fishing net dyeing, comprises the following steps：
（1）Pretreatment：Fishing net is put into absolute ethyl alcohol and soaks 30-40min, is then taken out, using cleaning and dipping 8-10min,
Then take out, be dried to constant weight；
（2）Corona treatment：By step（1）The fishing net of processing carries out corona treatment, processing time 3-5min；
（3）Weak acid is washed：By step（2）Fishing net after processing, which is added in weak acid solution, soaks 15-20min, then takes out, and uses
Clear water is washed to neutrality, is dried to constant weight；
（4）Dyeing：By step（3）The fishing net of processing carries out dyeing processing, is specially：Fishing net is immersed in overflow dyeing machine at room temperature
In clear water, acid dyes 50.2-52.2g/L, glycerol stearate monoesters 0.3-0.5g/L, cerium chloride are then added into clear water
0.0015-0.0018g/L, sodium gluconate 0.6-0.8 g/L, acrylic acid 0.12-0.15 g/L, bath raio 10:1, then pass through
The pH value of dye liquor is adjusted to 5.0-5.2 by pH buffer, when overflow dyeing machine then being warming up into 55 DEG C, is incubated 2min, is then added
Acid dyes quality 6-8% soybean protein-beta cyclodextrin and 0.1-0.3% glycine betaine, 10min is stirred with 500r/min rotating speeds,
Insulation stands 15min and then overflow dyeing machine is rapidly heated when rising to 88 DEG C, insulation dyeing 20min, and then overflow dyeing machine cools, and is down to room
Wen Shi, dyestuff raffinate is discharged, fishing net surface is rinsed with clear water, is then dried to constant weight, you can.
Further, the step（1）Middle soaked in absolute ethyl alcohol temperature is 55 DEG C, and clear water soaking temperature is 40 DEG C.
Further, the step（2）Plasma processing, processing gas is carbon dioxide, and processing pressure is
98KPa。
Further, the step（3）Middle weak acid solution is the acetum that mass fraction is 2%, soaking temperature 45
℃。
Further, the step（4）Middle acid dyes is azo dyes.
Further, the step（4）Middle soybean protein-beta cyclodextrin preparation method is：
（1）Beta-schardinger dextrin is added to the water dissolving, the beta-schardinger dextrin solution that mass concentration is 10% is made, is heated to 35 DEG C, then
The soybean protein and 0.02% pungent two methyl ester imidate of beta-schardinger dextrin solution quality 5% are added, obtains mixing after stirring molten
Liquid, using mass fraction, the pH value for adjusting mixed solution is 5.5 for 5% hydrochloric acid solution；
（2）Every 40min to step（1）Middle mixed solution carries out microwave treatment 3min, continues 5 hours, obtains reaction solution；
（3）Rotary evaporation concentrate drying is carried out to reaction solution, solids is obtained, attrition grinding, crosses 150 mesh sieves, produce.
Further, the fishing net is any of polythene fishing net or nylon fishing net.
The present invention can effectively be cleaned to fishing net surface by the pretreatment to fishing net, be removed impurity removing, avoid fishing
The impurity of net surface in fishing net dyeing course to causing to dye uneven phenomenon appearance, by carrying out low-temperature plasma to fishing net
Body processing, can effectively improve fishing net surface charge distribution so that and fishing net positive surface charge can be gathered effectively together,
So as to effectively effectively be attracted anionic dye during dyeing, and ionic bond is combined to form, carried
The adhesion of high dyestuff, by adding soybean protein-beta cyclodextrin and a certain amount of beet that the present invention prepares in dyeing course
Alkali, by soybean protein-beta cyclodextrin can with the hydroxyl on the carboxyl and amino groups and dye molecule on fishing net surface,
Amino etc. is complexed, and using this characteristic, during fishing net dyes, adds soybean protein-beta cyclodextrin and glycine betaine,
Absorption is enabled to, as a kind of intermediary, to be correspondingly improved dyestuff to fishing net table in the soybean protein-beta cyclodextrin on fishing net surface
The affinity in face, dye-uptake and colour fixation are improved so as to reach, and by the effect of glycine betaine, can promote dye molecule,
Firm tridimensional network is formed between fishing net and soybean protein-beta cyclodextrin, and then further improves colour fixation.
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, reduce dyeing process risk.

Comparative example 4：Step is differed only in embodiment 1（4）In do not add glycine betaine.
Comparative example 5：Differed only in embodiment 1 by step（4）Middle soybean protein-beta cyclodextrin replaces with the ring of equivalent
Dextrin.
Experiment：Embodiment is respectively adopted to dye the nylon fishing net that same quality of lot is 2kg with comparative example method, uses
Ultraviolet specrophotometer test dyeing stoste optical density, records dye liquor raffinate absorbance, records each time of half dyeing：
Time of half dyeing：Time of half dyeing is to reach the time required for equilibrium adsorption capacity half to dyestuff on fishing net, and time of half dyeing is
A very important performance indications of fishing net are contaminated on dyestuff, time of half dyeing is shorter, and dyestuff dyeing rate is faster；
Table 1
| Time of half dyeing | |
| Embodiment 1 | 9min02s |
| Embodiment 2 | 9min04s |
| Embodiment 3 | 9min03s |
| Comparative example 1 | 12min22s |
| Comparative example 2 | 10min01s |
| Comparative example 3 | 14 min15s |
| Comparative example 4 | 12min12s |
| Comparative example 5 | 15min21s |
As can be seen from Table 1, the fishing net time of half dyeing dyed by the inventive method greatly reduces；
Fishing net after being dyed to above-mentioned experiment carries out washing fastness test, is graded using standard grey scale, as a result such as table
2：
Table 2
| Colour fading fastness/level | Staining fastness/level | |
| Embodiment 1 | 5 | 4 |
| Embodiment 2 | 5 | 4 |
| Embodiment 3 | 5 | 4 |
| Comparative example 1 | 4 | 3 |
| Comparative example 2 | 4 | 3 |
| Comparative example 3 | 3 | 2 |
| Comparative example 4 | 4 | 3 |
| Comparative example 5 | 3 | 2 |
As can be seen from Table 2, it is higher by the pretreated fishing net dyefastness of the present invention.
