Patent CN100595373A provides a preparation method of super-hydrophobic cloth, in the method, citric acid and chloroauric acid are mixed to impregnate cotton fiber cloth, the cloth is transferred to an oven to be heated after impregnation is completed, and the cloth is immersed in an ethanol solution of dodecyl mercaptan for 6-8 hours after heating is completed. The preparation method needs chloroauric acid as a raw material, and chloroauric acid has high cost, is easy to decompose in the storage and transportation process and has large potential safety hazard.
Disclosure of Invention
The invention provides a preparation method of hydrophobic cloth aiming at the problems.
The technical scheme adopted by the invention is as follows:
a preparation method of hydrophobic cloth comprises the following steps,
s1: mixing and heating sodium citrate, sodium dodecyl benzene sulfonate, isopropanol, coconut diethanolamide and deionized water in proportion to 35-45 ℃, placing textile fibers in the mixed solution, treating the textile fibers with 20KHz ultrasonic waves for 5-10 min, and then placing the textile fibers in the deionized water, and treating the textile fibers with ultrasonic waves for 10-15 min;
the cleaning softener is prepared by mixing sodium citrate, sodium dodecyl benzene sulfonate, isopropanol, coconut diethanolamide and deionized water in proportion, and has the function of cleaning dirt such as grease on the surface of textile fibers and enabling the textile fibers to be more flexible; the deionized water is used for washing away residual sodium citrate, sodium dodecyl benzene sulfonate, isopropanol and coconut diethanolamide from the textile fiber.
S2: mixing acrylic acid, acetic acid, silicon dioxide particles, titanium dioxide particles, zinc dioxide particles, polyurethane resin and deionized water in proportion, heating to 50-60 ℃, then placing the textile fiber treated in the step S1 into the mixed solution, soaking for 10-15 min, and drying at 55 ℃;
step S2 is for coating a layer of hydrophobic nanoparticles on the textile fiber; the silicon dioxide particles, the titanium dioxide particles and the zinc dioxide particles are nano-scale particles and have good hydrophobicity, and the hydrophobic nano-particles are coated on the textile fibers in the step, so that each textile fiber has certain hydrophobicity;
s3: spraying the textile fiber treated in the step S2 with 0.05mol/L sodium bicarbonate solution and water in sequence, and drying after spraying;
step 3, washing off residual acrylic acid and acetic acid on the textile fibers, and washing the textile fibers by water spraying;
s4: weaving the textile fiber processed by the step S3 into cloth;
s5: mixing sodium citrate, citric acid, amino polydimethylsiloxane, silicone oil, ethoxy lauryl tyramine, deionized water and ethanol in proportion to form a treatment solution, maintaining the temperature of the treatment solution at 40-50 ℃, and performing padding treatment in the treatment solution for 20-30 min;
because the flexibility of the textile fiber is reduced after the textile fiber is processed in the step S2, the flexibility of the textile fiber needs to be improved after the textile fiber is woven into cloth, the formulas in the step S5 are combined together to form the surface treating agent, and the flexibility of the cloth can be improved after the cloth is padded in the surface treating agent, so that the cloth has certain antistatic capacity, and dust is not easy to stick to the surface of the cloth;
s6: the cloth processed in step S5 is dried after being washed with water.
Optionally, the mass ratio of the sodium citrate to the sodium dodecyl benzene sulfonate to the isopropanol to the coconut diethanolamide to the deionized water is 1: 3: 1: 2: 30.
optionally, the mass ratio of the acrylic acid, the acetic acid, the silica particles, the titanium dioxide particles, the zinc dioxide particles, the polyurethane resin, and the deionized water is 2: 2: 1: 1: 1: 8: 100.
optionally, the mixing sequence of the acrylic acid, the acetic acid, the silica particles, the titanium dioxide particles, the zinc dioxide particles, the polyurethane resin and the deionized water is that the acrylic acid, the acetic acid and the polyurethane resin are poured into the deionized water, and then the mixture of the silica particles, the titanium dioxide particles and the zinc dioxide particles is added while the liquid is stirred.
The proportioning method is adopted to ensure that the silicon dioxide particles, the titanium dioxide particles and the zinc dioxide particles are uniformly distributed in the mixed solution. Traditional hydrophobic cloth is generally only at surface coating nanometer silica granule, adopts the mode coating that three kinds of granules mix together in this scheme, for traditional single material coating, the granule between the different kinds is cross-linked with charge interaction's mode, and it is stronger to the repulsion of hydrone after forming the cross-linking between the granule, and the fibre surface is more difficult for being stained with water.
Optionally, the mass ratio of the sodium citrate to the citric acid to the amino polydimethylsiloxane to the silicone oil to the ethoxy lauryl tyramine to the deionized water to the ethanol is 2: 2: 3: 2: 3: 100: 50.
optionally, the rotation speed of the padder for padding treatment is 10r/min-15r/min, and the rolling residual rate is 80%.
Optionally, the textile fiber is a mixed textile fiber formed by combining cotton fiber and hemp fiber, and the mass ratio of the cotton fiber to the hemp fiber is 1: 1.
the comfort of the cotton fiber is stronger than that of the fibrilia, the strength of the fibrilia is stronger than that of the cotton fiber, and the cloth with high strength and high comfort is obtained by adopting a mode of mixing the cotton fiber and the fibrilia.
Optionally, the textile fibers are dried in a vacuum dryer at a temperature of 55 ℃ after impregnation.
Compared with the drying under normal pressure, the vacuum drying has the following advantages: 1. a drying speed block; 2. the volatilization of polyurethane in the drying process is reduced, and the adhesive strength of silicon dioxide particles, titanium dioxide particles and zinc dioxide particles on the surface of the textile fiber can be improved.
Optionally, the paint also comprises a polydimethylsiloxane solution, and a plurality of polydimethylsiloxane solutions are added after the acrylic acid, the acetic acid, the silicon dioxide particles, the titanium dioxide particles, the zinc dioxide particles, the polyurethane resin and the deionized water are mixed.
The addition of the polydimethylsiloxane solution serves to increase the viscosity of the entire solution, so that more silica particles, titanium dioxide particles and zinc dioxide particles are adhered to the textile fibers with a lower viscosity.
Optionally, the paint also comprises fatty alcohol-polyoxyethylene ether, and a plurality of fatty alcohol-polyoxyethylene ethers are added after the acrylic acid, the acetic acid, the silicon dioxide particles, the titanium dioxide particles, the zinc dioxide particles, the polyurethane resin, the deionized water and the polydimethylsiloxane solution are mixed.
The fatty alcohol-polyoxyethylene ether is added to enhance the osmotic strength of the silica particles, the titanium dioxide particles and the zinc dioxide particles, so that more silica particles, titanium dioxide particles and zinc dioxide particles are infiltrated into the textile fiber.
The invention has the beneficial effects that: the cloth obtained by mixing and coating the silicon dioxide particles, the titanium dioxide particles and the zinc dioxide particles on the textile fiber and weaving the textile fiber into cloth has good hydrophobicity and antistatic performance and is not easy to be stained with water and dust.
