Abstract
The invention relates to an ultraviolet nano-grade preparation method of super-hydrophilicity terylene fabric. According to the invention, nano-grade titanium dioxide is adhered to the surface of terylene fabric; the terylene fabric is irradiated by using ultraviolet rays, such that the surface of the terylene fabric is rapidly oxidized, and the terylene fabric is provided with super-hydrophilicity. Traditionally, only ultraviolet irradiation is adopted; and a water contact angle is reduced when the terylene fabric is irradiated for 700min. With the method provided by the invention, the terylene fabric is irradiated for 60min, and can be turned into super-hydrophilicity terylene fabric. As a result of experiments, a water contact angle is 0 DEG.
Description
Technical field
The present invention relates to the Textile Engineering technical field, particularly relate to a kind of ultraviolet nanometer titanium dioxide process of super hydrophilic dacron.
Background technology
Polyester fabric is most important fabric in the chemical fibre, accounts for about 60% of chemical fibre.Its good stiffness, fold elasticity make terylene have in textile industry, fabrics for industrial use widely and use.
But dacron hydrophilic is very poor, and the contact angle of water is very big.Therefore, report a lot about the hydrophilic finiss of dacron, the research of modification.As the terylene surface being carried out alkali decrement treatment, grafted protein matter to improve the hydrophily of dacron; Or carry out etching, carry out oxidation etc. with potassium permanganate with plasma, by endowing terylene fabric face hydrophilic radical to improve the hydrophily of dacron; Or by the fixing method of high temperature at dacron surface dressing one deck hydrophilic finishing agent, improve the hydrophily of dacron; Or when the terylene melt spinning, in polyester raw material, sneak into hydrophilic macromolecule etc., to improve the hydrophily of dacron; Or by ultraviolet ray irradiation, allow the dacron surface oxidation, and improving the hydrophily of fabric, or when ultraviolet ray shine, feed ozone, with the oxidation rate on raising dacron surface, thereby produce faster.
But the effect of above-mentioned these hydrophilic finiss methods is limited, many hydrophilies that can not increase substantially dacron, and perhaps the processing time is very long.As with ultraviolet ray irradiation dacron, shine 700min, the contact angle of dacron water is just from 70
oAbout drop to 20
oAbout.Therefore, the technology of the super hydrophilic dacron of the quick preparation of exploitation will have great application prospect.
Summary of the invention
The object of the present invention is to provide a kind of ultraviolet nanometer titanium dioxide process of super hydrophilic dacron.This method is compared with the method for only shining with ultraviolet ray, and speed increases substantially, and makes the ultraviolet ray irradiation more effective, can save plenty of time and the energy, and can prepare the dacron with Superhydrophilic, and making the contact angle of water on fabric is 0
o
Principle of the present invention is: nano titanium oxide has the ultraviolet ability of very strong absorption, simultaneously, the function that has very strong catalyzing organic oxidation after the absorption ultraviolet ray, therefore, after the nano titanium oxide, with ultraviolet ray irradiation dacron, the terylene surface can be oxidized rapidly on the dacron surface attachment, thereby make dacron have Superhydrophilic, the contact angle of water on dacron reduces to 0
o
The ultraviolet nanometer titanium dioxide process of a kind of super hydrophilic dacron of the present invention, realize through the following steps:
Under the normal temperature, nano titanium oxide is put into distilled water, stirring is mixed with the nano titanium oxide of 40 ~ 70g/L and the mixed liquor of water, then dacron is immersed in the mixed liquor of nano titanium oxide and water, vibration 20 ~ 25 min make dacron adhere to nano titanium oxide, take out then uviol lamp under shine 10min, when treating the dacron quick-drying, put it into again in the mixed liquor of nano titanium oxide and water and flood 5min, take out again and shine, after ultraviolet irradiation time reached 40 ~ 60min, the dacron water washed so repeatedly, dry, namely get the dacron with Superhydrophilic.
Advantage of the present invention:
Dacron adheres to after the nano titanium oxide, carries out treatment with irradiation with ultraviolet ray, and dacron can become the Superhydrophilic dacron rapidly.Only with the ultraviolet ray irradiation, dacron need shine 700min just can make the contact angle of water that certain decline is arranged to conventional method, uses the inventive method, and dacron only need shine 60min just can become the Superhydrophilic terylene, and experimental result shows that the contact angle of water is 0
