Abstract
The invention discloses a method for preparing an antibacterial and anti-ultraviolet fabric by virtue of in-situ hydrolysis, polymerization and nano-TiO2 loading. The method comprises the following steps: dissolving butyl titanate in an organic solvent; adding a fabric and carrying out absorption treatment; drying the fabric subjected to the absorption treatment in air or putting the fabric subjected to the absorption treatment in water, thus obtaining the target product. According to the method, butyl titanate serving as a precursor of nano-TiO2 is absorbed on the surfaces and internal nano pores of cotton fibers and is hydrolyzed in situ and polymerized to generate nano-TiO2. The method has the advantages that the operation is simple, the utilization rate of raw materials is high, no acidic raw material is used, the damage to fabric and fiber strength is avoided, and the product has soft handfeel and long-lasting antibacterial and anti-ultraviolet performances and can be washed many times.
Description
The application is application number: 201210197573.9, the applying date: 2012.6.15, title " antibiotic, the antiultraviolet fiber of load nano-titanium dioxide, the preparation method of fabric " divides an application.
Technical field
The present invention relates to a kind of antibiotic, antiultraviolet fiber of load nano-titanium dioxide, the preparation method of fabric.
Background technology
Antibiotic, the anti UV finishing of fabric, using at present maximum is nano titanium oxide.The method of utilizing nano titanium oxide to carry out modification to fabric or fiber mainly comprises direct method and post treatment method.Direct method refers to mixes direct wire drawing by nano titanium oxide with the fiber of melting, and this method is applicable to synthetic fiber.Post treatment method refers to nano titanium oxide is arranged 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 is arranged, its shortcoming be feel bad, be not suitable for and wear next to the skin, and easy wash-out; The second, used butyl titanate, acetic acid, ethanol etc. for raw material prepares colloidal sol, is padded on fabric, and drying and dewatering then, original position generates titanium dioxide nanoparticle, and its shortcoming is that 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 handlely, the prepared using degree is high, utilizes antibiotic, the antiultraviolet fiber of the load nano-titanium dioxide of in-situ hydrolysis polymerization, the preparation method of fabric.
Technical solution of the present invention is:
(1) butyl titanate is dissolved in organic solvent, adds fiber or fabric, adsorption treatment;
(2) fiber or fabric after absorption are placed in to air drying, or are placed in water and process, obtain the uvioresistant product.
(3) reacted fiber or fabric are placed in to the solution adsorption treatment containing the inorganic antibacterial ion, obtain antibiotic, uvioresistant product.
Step (3) directly is placed in the solution adsorption treatment containing the inorganic antibacterial ion by reacted fiber in air or in the aqueous solution; Or step (2) and (3) merging, fiber or fabric after absorption are placed in to the solution containing the 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 ℃.
In step (2) Air, drying is to dry or 40-120 ℃ of oven dry in room temperature; Described when being placed in water and processing, temperature is: room temperature ~ 90 ℃, time 0.5-4.0 hour.
It is the nano titanium oxide precursor that the present invention adopts butyl titanate, by butyl titanate, in absorption, in-situ hydrolysis, the polymerization of cotton fiber surface and inner nano pore, generates nano titanium oxide, and COTTON FABRIC is carried out to the uvioresistant modification.Utilize above-mentioned approach to carry out modification to natural fabric, not only easy and simple to handle, the prepared using degree 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, still have antibiotic uvioresistant performance (washing procedure: standard soap flakes liquid detergent concentration 2g/L; bath raio 1:30; 40 degree washings 5 minutes) method 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.
