Hydrophobic film.Therefore internal layer water can quickly be drained into outer layer cloth by the invention cloth, and internal layer keeps dry and comfortable, is suitable for clothing
The making material of object.But outer layer cloth is not hydrophobic, moisture still can soak design on fabric surface, therefore still be unable to satisfy dress
The decorations demand of cloth.
Patent CN105949499A discloses a kind of super hydrophobic material preparation method, comprising: passes through nanotechnology pair first
Base material arranges three-dimensional structure and is modified, and improves the roughness of material consolidation three-dimensional structure；Then pass through surface modification skill
Art, low-surface energy substance coat material, finally obtain super hydrophobic material.Although preparation process of the present invention is simple, reaction
Mild condition, but since the first step uses nano-TiO2Equal materials change base surface roughness, for decorative fabric
Speech, may change fabric color, influence to decorate display effect；And this method cladding low-surface-energy be using immersion by the way of,
It is easy to produce fluorine containing silane waste water.
Therefore, it is necessary to research and develop a kind of side that is simple, efficient and being generally applicable to a variety of textile fabrics surface super hydrophobics modifications
Method.
