Embodiment Construction

[0016] A preparation method for antibacterial and anti-ultraviolet fibers and fabrics loaded with nano-titanium dioxide, comprising the following steps:

[0017] (1) Dissolve butyl titanate in an organic solvent, add fibers or fabrics, and perform adsorption treatment;

[0018] (2) Dry the absorbed fibers or fabrics in the air, or place them in water to obtain UV-resistant products.

[0019] (3) The fibers reacted in the air or in the aqueous solution are directly placed in the solution containing inorganic antibacterial ions for adsorption treatment to obtain antibacterial and anti-ultraviolet products.

[0020] Described organic solvent is dehydrated alcohol, acetone or Virahol etc.

[0021] In the total amount of butyl titanate and organic solvent in step (1), the volume percentage of butyl titanate is 1-20% (eg 1%, 10%, 20%).

[0022] In step (1), the bath ratio of butyl titanate solution to fabric or fiber is 1-50 (Example 1, 25, 50).

[0023] The time for adsorption t...

Abstract

The invention discloses a preparation method of antibacterial and anti-ultraviolet fiber/fabric loaded with nano-titania. The preparation method comprises the following steps: dissolving butyl titanate in an organic solvent, adding the fiber/fabric in the solvent and carrying out adsorption processing; and placing the fiber or fabric after the adsorption processing in air for drying, or processing the fiber/fabric in water, thus obtaining a product. According to the invention, butyl titanate is adopted as a nano-titania precursor, the nano-titania is generated through adsorption, in situ hydrolysis and polymerization of the butyl titanate on the surface of cotton fabric and nanopores in the cotton fabric, so that the preparation method is simple in operation, high in raw material availability, does not need any acidic raw materials, and can avoid the damage to the strength of the fiber and fabric. The product prepared by the method disclosed by the invention has soft handfeel, durable antibacterial and anti-ultraviolet performances and can be washed for multiple times.

Description

technical field [0001] The invention relates to a method for preparing antibacterial and anti-ultraviolet fibers and fabrics loaded with nanometer titanium dioxide. Background technique [0002] For the antibacterial and anti-ultraviolet finishing of fabrics, nano-titanium dioxide is the most widely used at present. The methods for modifying fabrics or fibers by using nanometer titanium dioxide mainly include direct method and post-treatment method. The direct method refers to mixing nano-titanium dioxide with molten fibers for direct drawing, and this method is suitable for synthetic fibers. The post-treatment method refers to finishing the nano-titanium dioxide on the fabric by means of padding or bonding, and its scope of application is wider. The post-treatment method is divided into two situations: the first one is to use nano-titanium dioxide powder and dispersant binder to make a functional finishing agent to finish the fabric. Elution; the second is to use butyl t...
