Abstract
The invention discloses a preparation method of an antibacterial and ultraviolet-resistant fabric based on nano titanium dioxide. The preparation method comprises the following steps: dissolving butyl titanate in an organic solvent, adding the fabric, and carrying out adsorption treatment; and drying the adsorbed fabric in air or placing the adsorbed fabric in water so as to obtain the product, namely, the antibacterial and ultraviolet-resistant fabric. According to the preparation method disclosed by the invention, the butyl titanate is adopted as a precursor of the nano titanium dioxide; the nano titanium dioxide is generated through adsorption, in-situ hydrolysis and polymerization of the butyl titanate on the surface of cotton fibre and an internal nano-channel; the preparation method is simple and convenient to operate and high in raw material availability; furthermore, any acidic raw material is unnecessary to use; damages to fibre and fibre strength can be avoided; the product is soft in hand feel and durable in antibacterial and ultraviolet-resistant property and can be washed repeatedly.
Description
The application is application number: the divisional application of 201210197573.9, the applying date: 2012.6.15, title " preparation method of antibacterial, antiultraviolet fiber, the fabric of load nano-titanium dioxide ".
Technical field
The present invention relates to a kind of preparation method of antibacterial, antiultraviolet fiber, fabric of load nano-titanium dioxide.
Background technology
Antibacterial, the anti UV finishing of fabric, what use was maximum at present is nano titanium oxide.Nano titanium oxide is utilized mainly to comprise direct method and post treatment method to the method that fabric or fiber carry out modification.Direct method refers to the direct wire drawing of fibers mixture by nano titanium oxide and melting, and this method is applicable to synthetic fiber.Post treatment method refers to and arranges nano titanium oxide on fabric by the means of padding or binding, and its scope of application is more extensive.Post treatment method is divided into two kinds of situations: the first, use nano-titanium dioxide powder and dispersant binder etc. to be made into functional finishing agent, fabric arranged, its shortcoming be feel bad, be not suitable for and wear next to the skin, and easy wash-out; The second, use butyl titanate, acetic acid, ethanol etc. to prepare colloidal sol for raw material, be padded on fabric, then drying and dewatering, in-situ preparation titanium dioxide nanoparticle, its shortcoming is colloidal sol is acid, damages the intensity of cellulose fiber peacekeeping fabric.
Summary of the invention
The object of the present invention is to provide a kind of easy and simple to handle, raw material availability is high, utilizes the preparation method of antibacterial, antiultraviolet fiber, the fabric of the load nano-titanium dioxide of in-situ hydrolysis polymerization.
Technical solution of the present invention is:
(1) butyl titanate is dissolved in organic solvent, adds fiber or fabric, adsorption treatment;
(2) fiber after absorption or fabric are placed in the solution containing inorganic antibacterial ion, polymerisation and adsorption treatment are synchronously carried out.
Described organic solvent is absolute ethyl alcohol, acetone or isopropyl alcohol.
In step (1) in butyl titanate and organic solvent total amount, the percent by volume of butyl titanate is 1 ~ 20%.
In step (1), the bath raio of butyl titanate solution and fabric or fiber is 1 ~ 50.
In step (1), the time of adsorption treatment is 5 minutes-2 hours, treatment temperature: room temperature ~ 70 DEG C.
The present invention adopts butyl titanate to be nano titanium oxide precursor, generates nano titanium oxide, carry out uvioresistant modification to COTTON FABRIC by butyl titanate in cotton fiber surface and the absorption of inner nano pore, in-situ hydrolysis, polymerization.Utilize above-mentioned approach to carry out modification to natural fabric, not only easy and simple to handle, raw material availability is high, and does not need to use any acid material, can avoid the damage to fabric and fibre strength.Product is soft, after experiencing 50 washings, antibacterial uvioresistant performance (washing procedure: standard soap flakes liquid detergent concentration 2g/L; bath raio 1:30; 40 degree of washings 5 minutes) method is still had to be applicable to cellulose fibre and fabric thereof; as cotton, fiber crops, viscose glue and real silk fabric etc., to can be used for health-care underclothes, medical gauze, clothes, drapery etc.
Below in conjunction with embodiment, the invention will be further described.
Detailed description of the invention
A preparation method for antibacterial, antiultraviolet fiber, the fabric of load nano-titanium dioxide, comprises the following steps:
(1) butyl titanate is dissolved in organic solvent, adds fiber or fabric, adsorption treatment;
(2) fiber after absorption or fabric are placed in air drying, or are placed in water and process, obtain uvioresistant product.
(3) reacted fiber in air or in the aqueous solution is directly placed in the solution adsorption treatment containing inorganic antibacterial ion, obtains antibacterial, uvioresistant product.
Described organic solvent is absolute ethyl alcohol, acetone or isopropyl alcohol etc.
In step (1) in butyl titanate and organic solvent total amount, the percent by volume of butyl titanate is 1 ~ 20%(example 1%, 10%, 20%).
In step (1), the bath raio of butyl titanate solution and fabric or fiber is 1 ~ 50(example 1,25,50).
The time of adsorption treatment is 5 minutes-2 hours in step (1), treatment temperature: room temperature ~ 70 DEG C (example 25 DEG C, 50 DEG C, 75 DEG C).
Air drying to dry or 40-120 DEG C (example 40 DEG C, 80 DEG C, 120 DEG C) dries in room temperature in step (2); The described water that is placed in is when processing, and temperature is: room temperature ~ 90 DEG C (example 25 DEG C, 50 DEG C, 90 DEG C), time 0.5-4.0 hour (example 0.5 hour, 2 hours, 4 hours).
Step (2) and (3) can also merge by the present invention, and the fiber after step (1) absorption or fabric are placed in the solution containing inorganic antibacterial ion, and polymerisation and adsorption treatment are synchronously carried out.
