Abstract

The invention discloses a method for constructing a surface of a fabric with ultraviolet protection and wash-resistant special wetting functions. The method comprises the following steps: dissolving titanium potassium oxalate in a mixed solution of water and diethylene glycol; uniformly stirring under the action of a magnetic rotor; filling the prepared solution in a hydrothermal reaction kettle; adding a clean fabric into the hydrothermal reaction kettle and putting the kettle in an oven for reaction for preparing a fabric with a nano-TiO2 membrane surface; soaking the fabric with the nano-TiO2 membrane surface in a silane solution to react; and then taking out the fabric to be dried to prepare the fabric having the fabric surface with ultraviolet protection and wash-resistant special wetting functions. The method has the advantages of simple process, easiness in operation, controllable reaction condition, wide application range, wide source of raw materials, low cost, no pollution, excellent anti-ultraviolet property, wash resistance, lasting and stable super-hydrophobic self-cleaning property and good oil-water separation, and the fabric is excellent in comfortableness and air permeability.

Description

technical field [0001] The invention relates to a construction method for constructing a special wettable titanium dioxide film layer with ultraviolet protection and water washing resistance on the surface of a fiber fabric. Background technique [0002] Ultraviolet rays (UV for short) can be divided into long-wave ultraviolet UVA (320-400nm), medium-wave ultraviolet UVB (280-320nm) and short-wave ultraviolet UVC (200-280nm) according to the radiation wavelength. It is 290~400nm. The higher the UV light absorption and reflectivity on the fabric, the lower the UV transmittance and the better the protective performance of the product. At present, the mechanism of UV protection of textiles mainly comes from the absorption and shielding effect of the fiber fabric itself on ultraviolet rays, or the use of shielding agents to absorb and reflect ultraviolet rays. Excellent anti-ultraviolet performance can be obtained by the treatment of shielding agent. There are two main treatme...
