Description
Technical Field
The invention belongs to the technical field of textile material post-treatment, and relates to a nano-structure active water ion generating device and application thereof.
Background
Polyester materials have become one of the fastest growing synthetic fibers in the textile industry in recent years due to their excellent properties of wash and wear resistance, good dimensional stability, wrinkle resistance, and rapid drying. However, compared to natural fibers (e.g., cotton), polyester fibers are less hydrophilic, with a moisture regain of only 0.42% as measured in a standard environment, and cotton has a moisture regain of about 8.5%. Due to poor hydrophilicity, the application of polyester materials is more limited.
At present, the surface modification method of the polyester fiber mainly comprises a chemical grafting method, a high-energy ray radiation grafting method, an ultraviolet light surface grafting method, a plasma surface modification method, an alkali treatment method and the like. However, among the above modification methods, the high-energy radiation grafting method, the ultraviolet light grafting method, and the plasma surface modification method have high requirements on reaction equipment, reaction atmosphere, and operators, and are difficult to realize industrial production, and the alkali treatment method, the chemical grafting method, and the like have high costs. Therefore, the polyester fiber surface modification technology which is efficient and feasible needs to be further explored.
The nano-structure active water ions are a two-phase substance structure formed by coating a large amount of active oxygen components (including hydroxyl free radicals, superoxide free radicals and the like) and electrons by nano-scale water droplets, and are successfully applied to the fields of air purification, food preservation, beauty and skin care and the like at present. The nano-structure active water ions are a novel environment-friendly technology, based on an electrostatic atomization theory, and are formed by applying high voltage to liquid water supplied by a metal capillary tube to form a Taylor cone under the action of electric shearing stress and form charged liquid drops through top jet flow, and the liquid drops are continuously dispersed under the interaction of coulomb repulsion and surface tension. The active water ions of the nano structure contain a large amount of active free radical components, have strong oxidability and are expected to be applied to surface modification of polyester materials.
At present, the existing nano-structure active water ion generating device on the market has the following problems:
(1) most of the nano-structure active water ion generating devices supply liquid in a semiconductor condensation mode, and the phenomenon of unstable liquid supply is easily caused by overhigh or overlow external environment humidity;
(2) the existing active water ion generating devices with nano structures are single-needle devices, the generation amount is limited, and the action efficiency is low;
(3) the electrodes of the existing nano-structure active water ion generating device are distributed in a ring shape, and the electric field intensity is low;
(4) the parameters of the existing nano-structure active water ion generating device are all set in a fixed value and are single, and the nano-structure active water ions with different sizes cannot be generated by changing the parameters of the generating device so as to meet the requirements of practical application.
Therefore, the research on the nano-structure water ion generating device which has stable liquid supply, high formed electric field intensity, capability of generating nano-structure active water ions with different particle sizes and high acting efficiency and the application of the nano-structure water ion generating device in the hydrophilic modification of terylene have very important significance.
