Description
Technical field
The present invention relates to function textile finishing technique field, particularly relating to a kind of hydrophobic performance can selfreparing water-fastness
The preparation method of fabric.
Background technology
Hydrophobic surface is tempting to be caused scientists closed greatly due to its potential using value during the decade past two
Note.Hydrophobic surface produces in reality, have broad application prospects in life, can be used for waterproof, antifouling, automatically cleaning, fluid and subtracts
Resistance, the field such as antibacterial.Therefore, study and method that hydrophobic material or surface are prepared in exploration, for hydrophobic new material development and
Application has great importance.
Wettability is a kind of characteristic of material, depends primarily on surface energy and the surface roughness of material.Research shows, knits
Thing surface has low surface energy, and when having micron-nanometer level coarse structure, the hydrophobicity of fabric is greatly improved.Cause
This, preparing hydrophobic surface typically has two kinds of approach: one is to modify low-surface energy substance on coarse solids surface, another kind be
Low-surface energy substance surface construction coarse microstructure.Accordingly, researchers develop the preparation side of multiple artificial super hydrophobic surface
Method.
The mechanical performance of fabric can greatly reduce after being immersed in water, and this is the most unfavorable for some application
's.Additionally, due to the demand with textile fabrics such as the clothes of water-proof function, packaging material is increasing, therefore have a lot
Research work concentrates on and realizes hydrophobic function on textile fabric.But, by Cassie-Baxter theorem, it is understood that structure
Make super hydrophobic surface and must simultaneously meet two conditions: low-surface energy substance and micro-nano compound structure.And low on hydrophobic surface
Surface energy substance is in use highly susceptible to ultraviolet light and irradiates the external force destructions such as decomposition, mechanical damage and lose, and leads
The hydrophobic performance causing whole surface is destroyed, and in order to improve the service life of material, preparation has the super-hydrophobic of self-repair function
Surface is the most necessary.In recent years, a lot of people has been had to be devoted to the research of selfreparing hydrophobic fabric preparation method, but this
A little methods are more complicated, and obtained fabric wash durability is bad.
In view of the foregoing, the present inventor's the most in addition research and innovation, can review one's lessons by oneself to creating a kind of new hydrophobic performance
The preparation method of multiple water-fastness fabric so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of hydrophobic performance can the water-fastness fabric of selfreparing
Preparation method, the present invention uses fluorine-containing polysilsesquioxane and polyacrylate to arrange real silk fabric, it is possible to increase fabric
Hydrophobic performance and washing fastness, prepared fabric is after destroying, and its hydrophobic effect can self-healing in wet condition.
The hydrophobic performance of the present invention can the preparation method of water-fastness fabric of selfreparing, comprise the following steps:
(1) fluorine-containing polysilsesquioxane is dissolved in organic solvent, in gained solution, adds polyacrylate, after mixing
To water repellent finishing agent；
(2) be impregnated in by fabric in the water repellent finishing agent that step (1) obtains, obtaining hydrophobic performance after rolling baking arrangement can be certainly
The water-fastness fabric repaired.
Further, in step (1), in gained solution, the concentration of fluorine-containing polysilsesquioxane is 1-6g/L.
Further, in step (1), organic solvent be the one in ethyl acetate, carbon tetrachloride and chloroform or
Several.

Further, in step (1), polyacrylate is polymethyl acrylate, polyethyl acrylate and polyacrylic acid
One or more in butyl ester.
Further, in step (1), after shearing uniformly, obtain water repellent finishing agent.
Further, in step (1), shear rate is 8000-12000r/min.
Further, in step (2), fabric is one or more in real silk fabric, bafta and wool fabric.
Further, in step (2), roll baking finishing technique and use two leachings two to roll method.
Further, in step (2), roll preliminary drying 1-5min and at 110-at baking finishing technique is included in 80-100 DEG C
The step of 1-3min is baked at 160 DEG C.
The present invention is also claimed a kind of prepared according to the methods of the invention hydrophobic performance and can the water-fastness of selfreparing knit
Thing.
Further, hydrophobic performance can selfreparing water-fastness fabric through destroy after, at the relative humidity of 80%-100%
Under, the hydrophobic performance of fabric can selfreparing.
Further, O is used2Plasma machine destroys hydrophobic performance can the water-fastness fabric of selfreparing.
Further, O used2O in plasma machine2Flow be 100-200SCCM, power is 100-200W, during destruction
Between be 1-3min.
The preparation method of the fluorine-containing polysilsesquioxane of the present invention is as follows:
(1) vinyl trichlorosilane is dissolved in organic solvent, is subsequently adding water and is hydrolyzed reaction, obtain the poly-sesquialter of cage modle
Siloxanes；
(2) above-mentioned cage modle polysilsesquioxane, fluorine-containing mercaptan and initiator are dissolved in organic solvent, obtain after ultraviolet polymerization
Fluorine-containing polysilsesquioxane.
