Description

Production process of antibacterial nano-printed cloth and special shaping and drying device thereof
Technical Field
The invention relates to the technical field of nano-printed cloth production, in particular to a production process of antibacterial nano-printed cloth and a special shaping and drying device thereof.
Background
Along with the improvement of living standard of people, the requirements of people on comfort, health, safety and decoration are continuously improved not only for keeping warm, but also for people, and people feel more advocating to comfortable and luxurious printed fabrics. Traditional textiles such as fibers and polymers are not resistant to microorganisms and substances produced by metabolism of the microorganisms, and microorganisms can be accumulated and proliferated on the surfaces of the textiles more easily. Particularly, necrotic skin cells attached to the surface of textiles, sweat and grease secreted by the skin, food and beverage stains, dust and the like provide a suitable living environment for the growth of microorganisms and are good mediums for the growth of the microorganisms. Therefore, for human health and to improve the sanitary living standard, it is necessary to control the living activities of microorganisms on the surface of the fabric.
Generally, the existing printed cloth has poor antibacterial performance, cannot effectively prevent the accumulation and proliferation of microorganisms on the surface of the printed cloth, gradually loses the antibacterial performance in the long-term use process, and has poor durability of the antibacterial function.
Furthermore, the design drying device that its adopted often only carries out drying and finalizing after the calico finishes the stamp in proper order in current calico production process, and it adopts the hot gas flow to heat usually, causes the calico design effect poor, and the calico size stability who produces is poor.
Disclosure of Invention
The invention solves the technical problems that: improve the antibacterial property of the printed cloth, ensure the durability of the antibacterial property of the printed cloth and improve the shaping effect of the printed cloth.

and 5: printing technology
Introducing the base cloth passing through the discharging roller into a printing machine for printing treatment to obtain printed cloth; then the printed cloth enters a feeding roller; wherein the printing speed is 40-48 m/min;
step 6: second shaping and drying
Introducing the printed calico passing through the feeding roller into a steam heating cavity, and carrying out steam heating at the temperature of 190-260 ℃; meanwhile, after the tension roller clamps the side edge of the printed cloth in a tension manner, the lifting shaping plate lifts and presses the surface of the base cloth for shaping.
Further, in the step 1, the terylene, the kapok fiber, the hemp fiber and the chitosan fiber are mixed according to the volume ratio of 5-8: 2 to 4:2 to 4: 1-3 to prepare a first mixed tow;
mixing nano fiber and bamboo fiber according to the volume ratio of 3-5: 1-2 to prepare a second mixed tow.
The first mixed tow is added with kapok fiber, hemp fiber, chitosan fiber and other materials in the terylene, so that the antibacterial performance of the fabric can be greatly improved; the addition of the nano-fibers in the second mixed tow can greatly increase the toughness of the fabric, thereby enhancing the durability and prolonging the service life of the fabric.
Further, when the third mixed tow is adopted to weave the inner layer of the base cloth, microcapsules with the grain diameter of 29-31 microns are sprayed on the surface of the inner layer of the base cloth; nano ions of titanium dioxide, silver ions, zinc oxide and copper ions are respectively and independently placed in the sprayed microcapsules; and the proportion of the sprayed four microcapsules is 1.
The antibacterial property of the base cloth can be further enhanced by spraying the microcapsule coated with the antibacterial metal ions on the surface layer of the base cloth; the microcapsule is wrapped with the inorganic antibacterial material and is sprayed on the inner layer of the base cloth, the durability of the antibacterial performance of the base cloth can be enhanced through the slow release of the inorganic antibacterial material, and the problem of the reduction of the antibacterial performance caused by repeated washing is effectively avoided.
Further, soaking the second mixed tow in an organic antibacterial agent for 10-12 h;
the organic antibacterial agent comprises, by weight, 6-8 parts of a polyurethane antibacterial agent, 8-10 parts of a quaternary ammonium salt antibacterial agent and 8-10 parts of a fatty imide antibacterial agent; the second mixed tow can have antibacterial property on the basis of high strength by soaking the organic antibacterial agent.
