Description
Technical Field
The invention relates to a preparation method of a bacteriostatic window curtain fabric, and belongs to the technical field of functional textile processing.
Background
The curtain is one of main products of home textiles, is widely applied to the life of people, and has a plurality of application demands in bedrooms, hotels, classrooms, meeting rooms, theatres and vehicles. The window shade has basic decoration and shading functions, and also has the functions of ultraviolet resistance, heat insulation, sound absorption, dust prevention and the like. At present, the requirements of the market on the window shades are higher and higher, better functionalities such as bacteriostasis, flame retardance, antifouling and the like are expected, and the researches on the material and function modification of the window shades are also increasing.
The coated window shade is prepared by coating and finishing common window shade fabric, and the functions of shading and the like are achieved after the coating agent is added with a light shading agent such as titanium oxide, carbon black or pigment and the like and subjected to multi-layer coating and finishing. When the light irradiates the coating, the light is reflected or absorbed to play a role of shading. Common window coverings are foam coatings, transfer coatings, and the like. The foam coating is most commonly used, the polymer used for the coating is uniformly mixed with air in a mechanical mode, so that micropores formed by gas are formed in the coating slurry, and then the coating slurry is formed into a continuous film on the surface of the curtain fabric, so that the shading effect is achieved, and meanwhile, the heat insulation effect can be provided for the fabric by the foam micropores. The transfer coating is to coat the reflective coating agent on the release paper, press the reflective coating agent with the fabric, and transfer and bond the reflective coating agent on the fabric.
The common coating slurry is mainly polyacrylate, and metal powder can be added into the coating slurry to form a metal coating, so that the coating has a good shading effect. The metal powder generally comprises silver powder and gold powder, the silver powder is substantially aluminum powder, the silver powder is formed by ball milling of metal aluminum, and the particles are flat, have high shielding function, can shield visible light, ultraviolet rays and infrared rays, and are easy to oxidize in air; the gold powder is copper zinc alloy powder and has relatively stable chemical property.
The invention establishes a preparation method of a bacteriostatic window curtain fabric. Firstly, utilizing chloroformate groups in menthyl chloroformate to react with amino groups in folic acid to generate menthol group modified folic acid, and then utilizing She Suanji groups to perform autoxidation copolymerization reaction with dopamine to generate menthol/folic acid/dopamine polymer micro-nano particles. Menthol structure in the particle has antibacterial performance, and folic acid and dopamine structure has ultraviolet resistance and shading performance. The particles are mixed with acrylic ester emulsion and coated on the surface of the fabric to prepare the multifunctional curtain fabric with antibacterial, shading and ultraviolet-proof performances.
At present, menthol/folic acid/dopamine polymer micro-nano particles with antibacterial and ultraviolet-proof functions are not reported at home and abroad, and micro-nano particles with similar structures are not reported at any for finishing textile coatings. It is reported that the polydopamine is utilized to modify the fabric, nano silver is reduced on the surface of the fabric, and antibacterial and ultraviolet-proof performances are endowed to the fabric. The technology is different from the reported method for modifying the polydopamine modified fabric in the following points: (1) In the technology, menthol groups in micro-nano particles are endowed with the antibacterial function of the fabric, and are part of the chemical structure of the micro-nano particles, and the thought of the menthol groups is completely different from that of nano silver or other antibacterial substances combined by adsorption in the report; (2) In the technology, folic acid and dopamine are utilized to form a unique micro-nano particle structure, and then the particles are mixed with polyacrylate emulsion for use, so that the method is completely different from a method for generating a polydopamine coating on the surface of a fabric. The reported polydopamine coating method cannot be used in combination with polyacrylate foam coatings. Therefore, the processing method related to the technology is different from the existing polydopamine coating finishing report.
Disclosure of Invention
Firstly, utilizing chloroformate groups in menthyl chloroformate to react with amino groups in folic acid to generate menthol group modified folic acid, and then utilizing She Suanji groups to perform autoxidation copolymerization reaction with dopamine to generate menthol/folic acid/dopamine polymer micro-nano particles; finally, the micro-nano particles and polyacrylate emulsion are mixed and coated on the surface of curtain fabric. Menthol groups in the micro-nano particles have antibacterial property, and folic acid groups and dopamine groups have ultraviolet-proof and shading properties, so that the curtain fabric is endowed with good antibacterial, ultraviolet-proof and shading properties.

(2) adding 10-50 g/L menthol group modified folic acid and 10-50 g/L dopamine hydrochloride into a buffer solution with pH of 8.0-8.5, stirring and reacting for 12-24 hours under the condition of contacting air, and freeze-drying to obtain menthol/folic acid/dopamine polymer micro-nano particles;
(2) Preparing menthol/folic acid/dopamine polymer micro-nano particle coated fabric;
treatment process recipe and conditions:
(1) weighing 3-5 g/L of menthol/folic acid/dopamine polymer micro-nano particles prepared in the step (1), wherein the volume fraction of polyacrylate slurry is 70-85%, the volume fraction of titanium dioxide slurry is 10-15%, the volume fraction of ammonium stearate emulsion is 2-10%, and the pH value is adjusted to 8-9 by ammonia water to obtain black color paste;
(2) 70-85% of polyacrylate slurry, 10-15% of titanium dioxide slurry, 2-10% of ammonium stearate emulsion and 8-9 of ammonia water to obtain white color paste;
(3) and (3) after foaming the color paste (the foaming ratio is 1:3-1:4), coating three layers of the color paste on the surface of the curtain fabric according to the order of the white color paste, the black color paste and the white color paste, and baking at 150-180 ℃ for 2-5 minutes after each coating to obtain the antibacterial and ultraviolet-resistant window curtain fabric.
