Description
Technical field
The present invention relates to function textile finishing technique field more particularly to a kind of hydrophobic performance can selfreparing it is water-fastness
The preparation method of fabric.
Background technology
Hydrophobic surface is tempting to be caused scientists and was greatly closed due to its potential using value during the decade past two
Note.Hydrophobic surface has broad application prospects in reality production, life, can be used for waterproof, antifouling, automatically cleaning, fluid and subtracts
The fields such as resistance, antibacterial.Therefore, research and the exploration method for preparing hydrophobic material or surface, development for hydrophobic new material and
Using having great importance.
Wetability is a kind of characteristic of material, depends primarily on the surface energy and surface roughness of material.Studies have shown that knitting
Object surface have low surface energy, and with micron-nanometer grade coarse structure when, the hydrophobicity of fabric is greatly improved.Cause
This, preparing hydrophobic surface, generally there are two types of approach：One is in coarse solids surface modification low-surface energy substance, another kind be
Low-surface energy substance surface construction coarse microstructure.Accordingly, researchers develop the preparation side of a variety of artificial super hydrophobic surfaces
Method.
The mechanical performance of fabric can be reduced greatly after being immersed in water, this is very unfavorable for certain application fields
's.Further, since having the demand of the textile fabrics such as clothes, the packaging material of water-proof function increasing, therefore have very much
Research work is concentrated on realizes hydrophobic function on textile fabric.However, by Cassie-Baxter theorems, it is understood that structure
It makes super hydrophobic surface and must simultaneously meet two conditions：Low-surface energy substance and micro-nano compound structure.And it is low on hydrophobic surface
Surface energy substance is highly susceptible to the external force such as ultraviolet light decomposition, mechanical damage and destroys and lose in use, leads
It causes the hydrophobic performance of whole surface to be destroyed, in order to improve the service life of material, prepares super-hydrophobic with self-repair function
Surface is very necessary.In recent years, many people are dedicated to the research of selfreparing hydrophobic fabric preparation method, but this
A little methods are more complex, and obtained fabric wash durability is bad.
In view of the foregoing, the present inventor is actively subject to research and innovation, can be reviewed one's lessons by oneself to create a kind of new hydrophobic performance
The preparation method of multiple water-fastness fabric makes it with more the utility value in industry.
