Description
Technical field
The invention belongs to textile finish field, and in particular to a kind of spinning post-finishing microcapsules and preparation method thereof
And purposes.
Background technology
In recent years, continuing to bring out due to the new treatment technology of textile material so that function textile is developed rapidly, and
An important new high-tech industry is become, wherein mosquito proof textile then becomes function textile research in recent years
One of focus.
Microcapsules technology is that a kind of with reactivity, volatility, sensitiveness or will have a material (core) of bad smell
It is encapsulated by filmogen (wall material), forms a kind of protection technique of fine particle, the process of encapsulating is referred to as microencapsulation,
The fine particle of formation is referred to as microcapsules.Mosquito proof microcapsules refer to by into membrane material by various mosquito-repellents and insecticide
Material is encapsulated a kind of fine particle to be formed, its under the process conditions such as temperature, humidity and time of regulation, by using
The auxiliary agents such as binder allow microcapsules and fiber containing repellant and insecticide to be combined together, so as to form one in fiber surface
Layer is not readily dissolved in the mosquito repellent medicine film of water and common organic solvents.
As Chinese patent application CN105603766A discloses a kind of composite essential oil microcapsule dressing agent, it is with galic essential oil
With eucalyptus leaf essential oil as core, it is obtained as wall material using gelatin and beta-schardinger dextrin, the pure cotton fabric after being arranged through the finishing agent has
There is the effect of good antibacterial and mosquito repellent.But galic essential oil and eucalyptus leaf essential oil are volatile, and heat endurance is poor, easily because in environment
Oxygen, light and heat go bad, the repelling effect for reducing microcapsules and the counter phase for shortening microcapsules.
In addition, existing microcapsule dressing agent is inadequate with the affinity of textile, it is easy to be come off from the surface of textile.
Therefore, it is necessary to providing, a kind of stability is high, repelling effect is excellent, and strong with textile affinity microcapsules are whole
Reason agent.

Preferably, the plants essential oil presses 1 by P-Cymene and cus-cus essential oil：0.3 weight is than composition.
Correspondingly, present invention also offers a kind of method for preparing above-mentioned microcapsules, comprise the following steps：
A) starch octenylsuccinate is dissolved in purified water the octene for being configured to that mass fraction is 1.0~3.0%
Base succinic acid esterification amidin；
B the casein-sodium aqueous solution that mass fraction is 2.0~8.0%) is configured to by casein-sodium is soluble in water, by nanometer
Microcrystalline cellulose is configured to casein-sodium-nano micro crystal cellulose-aqueous solution in being dissolved in the above-mentioned casein-sodium aqueous solution；

Plus acetum, the pH of regulation system is 4.0~4.8,40~55 DEG C of water bath with thermostatic control 0.5~2.0h of stirring reaction, obtains microcapsules
Suspension；
E) toward curing agent is added in the microcapsule suspensions, 50~60 DEG C of water bath with thermostatic control 1~3h of stirring reaction, spraying is dry
It is dry, obtain final product.
Preferably, emulsifying agent is stated for sucrose fatty ester, and the consumption of the sucrose fatty ester is the compositional liquor gross weight
The 1~3% of amount.
Preferably, the curing agent is Geniposide or tannic acid, and the consumption of the curing agent is the microcapsule suspensions
5~10%.
Preferably, the step E) in spray drying intake air temperature be 100~120 DEG C, air outlet temperature be 50~70
DEG C, atomizing pressure is 0.4~0.8MPa.
Another object of the present invention is the purposes for providing above-mentioned microcapsules in textile mosquito repellent finishing agent is prepared.
In the present invention plants essential oil as main effective mosquito component, inventor it was unexpectedly observed that by P-Cymene and
Cus-cus essential oil compounding use can significantly improve the repelling effect of textile.When core is P-Cymene or cus-cus essential oil,
The scattering ratio of textile is respectively 36% and 26%, but both are pressed into 1:0.3 weight is up to than compounding use, scattering ratio
89%, with extremely strong repelling effect.Trace it to its cause and be, the active component benzoic acid in cus-cus essential oil has fixation
Effect, it can extend the volatilization time of P-Cymene, so as to improve repelling effect, both have the effect of Synergistic.And make
Inventor surprisingly, the repelling effect of the textile after obtained microcapsules are arranged is compounded through P-Cymene and cedar wood oil
Effect is worse compared with both are used alone, when core is P-Cymene or cedar wood oil, the weaving after being arranged through the microcapsules
The scattering ratio of product is respectively 36% and 45%, and scattering ratio is only 38~43% during both compoundings.Separately through P-Cymene and folium eucalypti
Textile repelling effect after the obtained microcapsules of oil compounding are arranged is also barely satisfactory, and its compounding use is used alone phase with both
It is more little than increase rate.
In the prior art, L- methinyls base glycine hydrochloride is used in being often added to food as spices, inventor
It was unexpectedly observed that not increasing the effect of fragrance, its stabilization that can also improve plants essential oil in being added to plants essential oil only
Property, experiment shows that the microcapsules ratio that there is L- methinyl base glycine hydrochlorides in system is free of L- methinyl base glycinates
The repelling effect of hydrochlorate microcapsules is more longlasting.
Starch octenylsuccinate has good embedding rate to core with casein-sodium compounding cyst wall, and with good
Good mechanical strength, but it is poor with the affinity of textile.Inventor has found that addition nano microcrystalline is fine on the basis of the above
Dimension element can greatly increase the adhesive force of microcapsules and textile.Trace it to its cause and be, nano micro crystal cellulose can strengthen interface
Compatibility, by microcapsules and textile completely through getting up.
Compared with prior art, microcapsules of the present invention have the advantage that：
1) microcapsules that the present invention is provided have good mechanical strength, and with natural, safety, degradable advantage.
2) microcapsules that the present invention is provided have good affinity with textile, after being arranged through microcapsules of the present invention
Textile fragrance persistently, scattering ratio reaches 89%, with extremely strong repelling effect.
Specific embodiment：
Below by way of the description of specific embodiment, the invention will be further described, but this is not to limit of the invention
System, those skilled in the art's basic thought of the invention, various modifications may be made or improves, but without departing from this
The basic thought of invention, within the scope of the present invention.
