Disclosure of Invention
In order to solve the problem of poor antibacterial durability of the curtain in the related technology, the application provides a treatment process of the antibacterial curtain.
The application provides a treatment process of an antibacterial curtain, which is realized through the following technical scheme: a treatment process of an antibacterial curtain comprises the following steps:
firstly, preprocessing a polyester curtain fabric;
Secondly, carrying out erosion treatment on the fiber surface in the polyester curtain fabric;
step three, placing the polyester curtain fabric into pure water, carrying out ultrasonic cleaning for 1-2 hours, and drying until the moisture content is lower than 5%;
step four, carrying out vacuum coating treatment on the polyester curtain fabric dried in the step three, and evaporating a nano silver antibacterial layer on the fiber surface of the polyester curtain fabric;
step five, putting the mixture into pure water dissolved with a surfactant, soaking the mixture for 1 to 2 hours at the temperature of between 20 and 25 ℃, and drying the mixture at a low temperature until the water content is less than 10 percent;
step six, forming a protective layer on the fiber surface of the polyester curtain fabric by adopting an electropolymerization method, and washing with pure water;
and seventhly, softening, drying and shaping to obtain the finished antibacterial curtain.
By adopting the technical scheme, the bonding strength of the antibacterial component and the fibers in the polyester curtain fabric is good, the antibacterial component is protected by the protective layer formed by an electropolymerization method, and the antibacterial rate is still kept to be more than 80% after the antibacterial component is washed for 40 times, so that the antibacterial curtain with better antibacterial property, antibacterial durability, mildew resistance and mildew resistance durability can be prepared by adopting the treatment process.
Preferably, the specific operation of the fourth step is as follows: weaving terylene curtain Placing the material into a vacuum chamber of a magnetron sputtering coating machine, vacuumizing the sputtering chamber, and controlling the vacuum degree to be 1 x 10-3Injecting argon into the sputtering chamber under the pressure of 0.01Pa to reach the working pressure of 0.20-0.50 Pa; the target material is silver target, the target base distance is set to be 10cm, the sputtering current is 1A, and the silver target material is sputtered on the fiber surface of the terylene curtain fabric by adopting the magnetron sputtering technology to form the nano silver antibacterial layer.
By adopting the technical scheme, the nano silver antibacterial layer is formed on the surface of the yarn of the polyester curtain fabric by the magnetron sputtering technology, the bonding strength between the nano silver antibacterial layer and the fiber in the polyester curtain fabric is good, and the antibacterial durability of the curtain fabric can be effectively ensured.
Preferably, the surfactant in the step is a basf XL 40 nonionic surfactant, and the mass ratio of the surfactant to pure water is 1: 120-200.
By adopting the technical scheme, the specific basf XL 40 nonionic surfactant is selected because the specific basf XL 40 nonionic surfactant has a good effect of treating the surface of the fiber in the polyester curtain fabric and does not corrode or peel off the nano silver antibacterial layer.
Preferably, the electropolymerization method in the sixth step specifically operates as follows: firstly, preparing an electrolyte, wherein the electrolyte is prepared from the following raw materials in parts by mass: 100 parts of deionized water, 0.1-0.8 part of electrolyte, 0.5-8 parts of polymerization monomer and 3-20 parts of organic solvent, placing the polyester curtain fabric in the step five as a cathode in the prepared electrolyte, selecting graphite as an anode, wherein the electrolyte of the anode is 0.5-5% of sodium chloride solution, the voltage of electropolymerization is 3.6-5.0V, the electropolymerization time is 5-20s, washing the electropolymerized polyester curtain fabric for 3 times by using pure water, and the washing time is 10mim each time.
Through adopting above-mentioned technical scheme, form the polymer that has the guard action outside the fibre of dacron curtain fabric, play the effect that promotes the bacterinertness and antibiotic persistence of this application.
Preferably, the electrolyte is sodium nitrate; the polymerization monomer is one of vinyl acetate, styrene and acrylamide; the organic solvent is one of dimethyl sulfoxide, dichloromethane and N, N-dimethylformamide.
By adopting the technical scheme, the polymer can be formed outside the fibers of the polyester curtain fabric, the fibers are protected, specifically, the antibacterial nano silver on the surfaces of the fibers can be coated, the falling probability of the antibacterial nano silver is reduced, and the aim of keeping a higher antibacterial rate after multiple times of washing is fulfilled, so that the antibacterial property and the antibacterial durability of the polyester curtain fabric are improved.
Preferably, the pretreatment operation in the step one is as follows: placing the polyester curtain fabric in 0.5-2.5g/L of dispersing agent and 1.0-2.5g/L of penetrating agent, soaking for 30min in a treatment solution with a water bath ratio of 1:10-20 and a water temperature of 60 +/-5 ℃, and washing for 3 times by using deionized water at 35 +/-5 ℃, wherein the washing time is 10mim each time.
By adopting the technical scheme, grease on the surface of the yarn in the polyester curtain fabric can be effectively removed. And impurities such as dust, glue and the like are convenient for subsequent coating treatment, so that the bonding strength of the coating and the fibers in the polyester curtain fabric is ensured.
