Abstract
The invention discloses a method for modifying a fabric by a UV light-cured responsive sol, and belongs to the field of functional textiles. The method comprises the following steps: sequentially adding an ethanol solution of a double bond silane coupling agent and an ethanol solution of a hydrophobic silane coupling agent to a prepared acidic SiO2 hydrosol to prepare a reactive SiO2 sol, processing the reactive SiO2 sol onto a fabric, and initiating photopolymerization by UV lights to obtain a modified fabric with hydrophobic performances. The method for modifying the fabric has the advantages of no high temperature treatment, reduction of the influences of high temperature on the strength and the hand feeling of the fabric, and reduction of the yellowing phenomenon of the fabric. The method improves the curing efficiency, and saves 80% of energy through adopting the UV lights to substitute heat energy.
Description
Technical field
The present invention relates to the method for the sol-gel modified fabric of a kind of UV photocuring reaction, belong to function textile modification field.
Background technology
Receive publicity gradually in the research of textiles flexible parent metal surface construction super hydrophobic surface, this is because textiles is cheap, easily process, easy coloring, can large area produce.Prepare super-hydrophobic textile and first construct suitable roughness at textile surface, then surface-hydrophobicized modification is carried out to the textile surface with coarse structure.The method of constructing micro-nano coarse structure at textile surface mainly contains: sol-gel process, hydro-thermal method, layer assembly method, polymer modification method, nanometer particle load method.But no matter that method is all solidification means with thermal source.After textiles heat treatment, its feel can be affected, and cloth cover also can turn yellow, and affects its wearability.Therefore it is very necessary for seeking a kind of new curing mode.
Light Curing is a photochemically reactive process, and its coating is the shortest can complete solidification within the several seconds, and production efficiency is significantly improved, and more meets the requirement of the extensive automation of modern industry.Institute's energy requirement saves about 80% in the curing process.Solidification process only need can carry out at normal temperatures, and this is that additive method cannot be reached.Photocureable coating, only containing seldom or substantially not containing volatile solvent, effectively can reduce VOC discharge in work progress.In Light Curing, nearly all component all participates in cross-linking reaction, effectively reduces air pollution, harm reduction.Photocureable coating can be coated with and be contained on multiple base material, as metal, plastics, rubber, wooden, leather, paper etc.The application of photocuring technology, can effectively reduce in the process of heat cure, high temperature is to the infringement of heat-sensitive material.Photocuring only needs ultraviolet light polymerization equipment, belongs to one-time investment, saves space and the energy, and ultraviolet light polymerization automation degree of equipment is high, can reduce investment, reduce costs.
