Definitions

  • the present invention relates to a process of manufacturing textile barrier materials from polyester fibers or their blends containing other fibers by sulfate and/or emulsion precipitation method as opposed to well-known hydrolysis and condensation of organic precursors (the so-called sol-gel method).
  • These materials demonstrate an exceptional resistance to UV radiation and microorganisms as well as photocatalytic properties thanks to introducing into the structure of the textile material the anatase type of titanium dioxide or its oxygen composite Ti0 2 -Si0 2 the size of nano- and micrometric particles.
  • the barrier properties of the textiles against UV radiation may result from the dense textile texture, as described in the patent EP644820B 1. They can also be effectively improved by, among other things, the use of UV absorbers, which are colorless substances that absorb radiation in the wavelength range of 290-400 nm. Depending on the mechanism of action, the UV absorbers can be divided into two groups:
  • Inorganic absorbers or so-called physical blockers, which reflect and scatter UV radiation.
  • the most commonly used blockers are zinc oxide (ZnO) and titanium dioxide (Ti0 2 ).
  • Nano- Ti0 2 with highly developed surface of contact has the ability to block UV radiation and possesses self-cleaning (photocatalytic) properties. For this reason, it is readily applied to textiles. Due to its high capacity for UV absorption, as well as reflection and scattering of UV radiation, titanium dioxide is used as a physical blocker of UV radiation, increasing the barrier capacity of the textiles it modifies.
  • the patent application JP 2006321087 (A) describes the barrier material based on polyester containing metal oxides such as silicon, titanium, tin, zinc, aluminum, indium.
  • the anatase type titanium dioxide for modification of polyester textile material is also described in the following JP patent applications: 08-276397, 08-281715, 07-206059, 06- 142167, 01-115764, 01-014066.
  • Ti0 2 -Si0 2 oxide composite One functional material with special useful properties is the Ti0 2 -Si0 2 oxide composite.
  • the degree of dispersion of titanium dioxide is much greater, and its activity is higher. This also contributes to the transformation from anatase to rutile form, which prevents the growth of titanium dioxide particles during thermal treatment.
  • silica increases the specific surface area of titanium dioxide and contributes to the formation of ⁇ Ti-O-Si ⁇ bonds. All of this increases photocatalytic activity of the Ti0 2 - Si0 2 composite [Ren S., Zhao X., Zhao L., Yuan M., Yu Y., Guo Y., Wang Z., Journal of Solid State Chemistry.
  • Silica-coated titanium dioxide shows a higher thermal and mechanical stability, at the same time a reduced tendency for agglomeration of the particles and an increase the surface activity of the final product are observed.
  • the nature of the invention is the method for obtaining textile barrier material against UV radiation and microbes, while using titanium dioxide particles of the anatase type which are micronized by means of alkoxysilanes or its Ti0 2 -Si0 2 oxide composite introduced into the structure of textile material.
  • the process is performed in two stages.
  • the first stage consists in proper preparation of the textile material in order to increase its adhesive properties.
  • the surface of the polyester fibers is modified by low temperature plasma treatment (non-equilibrium) in the atmosphere of various gases, preferably carbon dioxide or argon.
  • Another way to modify the surface is a controlled treatment of the textile product in a solution of sodium hydroxide at a temperature above 90° C.
  • micronized particles of titanium dioxide of the anatase type or its oxide composites are introduced into the structure of the textile material in the amount that is not less than 0.5 wt%. and not more than 10% by weight.
  • Polyester fiber products are padded with aqueous dispersion containing micronized particles of functionalized Ti0 2, a wetting agent, and a thickening agent.
  • the dispersion is subjected to intense homogenization by means of a homogenizer at the proper time and speed. Once the padding has been completed in a two-roller padding machine, the excess of dispersion is removed from the samples in order to obtain an adequate level of deposition. Then, the samples are dried and heated up in a heat coating machine.
  • aqueous dispersion with 1-5 wt.% of the modified Ti0 2 preparation, a wetting agent - polyethylene glycol (PEG) in the amount of 5-15 wt%. and hydroxyethyl cellulose thickener (HEC) - in the amount of 1-5 wt%.
  • PEG polyethylene glycol
  • HEC hydroxyethyl cellulose thickener
  • Another way of incorporating Ti0 2 particles into the structure of the textile product is coating.
  • a properly prepared paste on the basis of acrylic resin and containing the modified titanium dioxide of nano- and micrometric size, a thickening agent, and a wetting agent are applied to a textile carrier using a special kit for application of nanostructured film coatings.
  • the film's thickness is controlled by adjusting the feeding slot/gap between the coating blade and the textile material being coated.
  • the product with the applied coating is dried and heated up.
  • paste containing 1-3 wt.% of modified Ti0 2, a wetting agent - polyethylene glycol (PEG) in the amount of 5-15 wt.%, styrene-acrylic resin with no more than 20 wt.%, acrylic thickening agent of 3-10 wt.%.

  • An anatase sample was placed in a reactor with the capacity of 500 cm 3 and sprayed with the 3-Methacryloxypropyltrimethoxysilane solution by means of a special spray system (atomizer).
  • the solution contained a binding silane compound in the amount of 0.5 wt. parts of silane per 100 wt. parts of anatase.
  • the binding silane compound was hydrolyzed in a mixture of methanol and water at the volume ratio of 4: 1. Then, the system was stirred for 1 hour in order to perfectly homogenize the anatase sample with the solution of the modifying compound and the solvent was distilled off.
