Abstract
The invention discloses a finishing method of automatic-cleaning textiles. The method comprises the following steps: padding the textiles in a dipping liquid containing an automatic-cleaning finishing agent, drying under conditions comprising that the pressure is 2.5-3kg/cm<2> and the liquid carrying rate is 60-70%, and carrying out temperature maintenance of the textiles at 115-150DEG C for 0.5-2h, wherein the automatic-cleaning finishing agent comprises the following components, by weight, 75-90 parts of nanometer titanium dioxide, 5-10 parts of a cationic surfactant, 0.2-1 part of a sodium polyacrylate dispersant and 100-500 parts of water. The automatic-cleaning textiles have strong durability, and have an excellent automatic-cleaning function.
Description
Technical field
The present invention relates to a kind of method for sorting of automatically cleaning textiles.
Background technology
Utilize nano-TiO
2Photodegradation, can effectively remove the part harmful substance.Nano-TiO
2Under the irradiation of ultraviolet ray or daylight, can be with oxychloride, formaldehyde catalytic degradation.Its principle is TiO
2When being subject to the ultraviolet ray irradiation, will produce free electron and hole, they make airborne oxygen activation, produce reactive oxygen species and free radicals, and some organic pollution is decomposed into CO the most at last
2And H2O.Contain nano-TiO
2Non-weaving cloth or textiles, can make curtain, sheet, wall paper, carpet, furniture and car and boat with cloth, various adornments etc., also can be used as the purified treatment articles for use of air and waste water.But prior art adopts direct method for sorting, because nano-TiO
2Interfacial effect, itself and fibrous binding force are not strong, cause the durability of finished product and water-wash resistance poor, affect its result of use.Develop a kind of automatically cleaning textile product with excellent durability and become important research topic.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method for sorting of automatically cleaning textiles, the defects that exists to overcome prior art.
For solving the problems of the technologies described above, the method for sorting of automatically cleaning textiles of the present invention comprises the steps: textiles is padded processing in containing the maceration extract of self-cleaning finishing agent pressure 2.5～3kg/cm
2, liquid carrying rate 60～70%, after the oven dry with fabric constant temperature 0.5～2 hour between 115～150 ℃;
Described self-cleaning finishing agent is comprised of the component of following weight portion:
75～90 parts of nano titanium oxides;
5～10 parts of cationic surfactants;
0.2～1 part of Sodium Polyacrylate dispersant;
100～500 parts in water.
Self-cleaning finishing agent can adopt general mixed method, preferably adopts following method preparation:
Nano titanium oxide, Sodium Polyacrylate dispersant and water mixed to be made into mass content be 20～60% water slurry, then in suspension, add cationic surfactant at twice, add for the first time 50% cationic surfactant, add for the second time remaining cationic surfactant, needed respectively to mix 0.5～3.0 hour behind twice adding cationic surfactant.
Described cationic surfactant comprises one or more in dodecyl benzyl dimethyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, cetalkonium chloride, stearyl dimethyl benzyl ammonium chloride, hexadecyltrimethylammonium chloride, softex kw, the hexadecylpyridinium chloride.
Preferred average grain diameter 20～80 nanometers of nano titanium oxide, preferred nanometer anatase titania;
Described Sodium Polyacrylate dispersant preferred viscosities 200～250mPas.
The present invention adds cationic surfactant in the nano titanium oxide water slurry, cationic surfactant one end is the very strong CATION of polarity, and the other end is the very weak long hydrocarbon chain of polarity.Cationic surfactant adds at twice, after surfactant adds for the first time, CATION one end that surfactant polarity is very strong and the anion generation effect on nano titanium oxide surface, SURFACTANT ADSORPTION is to the titanium dioxide nanoparticle surface, the long-chain hydrocarbon that other end polarity is very weak covers the titanium dioxide nanoparticle surface, makes the titanium dioxide nanoparticle surface become low pole.After surfactant adds for the second time, surfactant low pole long-chain hydrocarbon can with the generation effect of the titanium dioxide nanoparticle of low pole surface, the surface of the cation nanometer titanium dioxide granule that other end polarity is very strong, make positive charge on the original electronegative titanium dioxide nanoparticle surface band, make nano titanium oxide become cationic.The cation nanometer titanium dioxide of this surface band positive charge, can with fabric surface with negative electrical charge produce strong effect, make titanium dioxide nanoparticle be adsorbed on firmly fabric surface.Automatically cleaning textiles durability of the present invention is strong, has good self-cleaning function.
