Antistatic And Antimicrobial Finishing Of Fabrics Based On Tin Antimony Oxide And Copper Oxide

With the improvement of people's living standards,new requirements are put forward for textiles.Anti-static as a long-standing problem,has been subject to people's attention.In mines,operating tables and other environments,the hazards caused by static electricity are unimaginable.Polyester fabric is widely used as a synthetic fiber,and is loved by people for its unique and excellent performance.However,polyester fibers are prone to static electricity,so antistatic finishing of polyester is of great significance.On the other hand,with the prevalence of neo-coronaviruses,the control of viruses and bacteria is at an all-time high.Textiles are closely related to people and are worn by people close to the body.Cotton fabric as the earliest human contact with the fabric,has become an indispensable part of people's lives.Because of its hydrophilic properties,cotton fiber making it easy for bacteria to grow on cotton fibers' surfaces.Therefore,the development of antimicrobial cotton fabrics is of great importance.In this paper,we start with the conduction and radiation in static leakage,and describe the antistatic mechanism of antistatic materials and the process of static elimination,and analyze the advantages and disadvantages of existing antistatic materials,as well as the development direction of antistatic finishing.The use of metal oxides for antistatic finishing of fabrics allows the fabric to quickly complete the static leakage to achieve antistatic effect.Tin antimony oxide(ATO)is an N-type semiconductor with electrons on its surface that give it a high electrical conductivity,making it useful for antistatic finishing.On the other hand,this paper starts with the antimicrobial mechanism and describes the mechanism of action of various antimicrobial agents and the direction of development of antimicrobial fabrics..Metal oxides can be quickly sterilized by the photocatalytic antibacterial mechanism,with less restrictions and good durability.Copper oxide is a P-type semiconductor that can produce reactive oxygen under photocatalytic conditions,givingit antimicrobial efficacy.This article starts from the research and development of antistatic polyester fabric and antibacterial cotton fabric.The first part investigates the optimal ATO antistatic coated polyester fabric and ATO sol-treated polyester fabric for the antistatic process.In the second part,the antimicrobial fabrics with copper oxide grown on the surface are prepared in combination with ultrasonic chemistry,and the optimal process is investigated.Preparation of ATO antistatic coatings by mixing ATO with polyurethane.The antistatic coating obtained through the coating process has good durability.An antistatic coating with an electrostatic half-life of 0.24 s and a peak voltage of 297 V was obtained after single-factor and quadrature experiments.The fabric,which can withstand up to 20 washes.Second,the ATO sol was prepared by the sol-gel method.Particle size and polydispersity.After single-factor and orthogonal experiments,the electrostatic half-life of the prepared antistatic fabric can reach 0.02 s and the peak voltage is 267 V.The resulting antistatic polyester fabric has excellent wash fastness and can withstand up to 20 washes.Characterized by X-ray diffractometer(XRD),X-ray photoelectron spectrometer(XPS),X-ray energy dispersive spectroscopy(EDS)and field emission scanning electron microscope(FE-SEM),after treatment,the fabric surface forms a uniform layer ATO film.Finally,the cotton fabric was placed in a copper sulfate/sodium hydroxide mixed solution by ultrasonic chemical method to prepare copper oxide antibacterial cotton fabric.XRD,EDS,XPS and FE-SEM show that Copper oxide is formed on the surface of the fabric,and the copper oxide grows evenly on the surface of cotton fabric.Since the cotton fabric after the copper oxide treatment shows good UV protection performance,UPF can be used to characterize the copper oxide content on the surface of the fabric to a certain extent.The antibacterial rate of cotton fabric with UPF index of 184.23 against Staphylococcus aureus is greater than 99.9%.
