By the Iranian researchers it was done; with nanotechnology, the high resistance of genuine leather against the flame in the production of natural leather
Iranian researchers at Amir Kabir University of Technology have succeeded in achieving a project to upgrade genuine leather against flame with nano technology in genuine leather production.
The Iranian researchers at Amir Kabir University of Technology, Samaneh Sepehri, who was implementing the “improvement of the natural regeneration of genuine leather against flame by adding clay nanoparticles,” stated:
The leather industry in Iran has a long history, but with the passing of years of presenting the machinery of this industry in the production of leather into the country, there are many problems in the industry.
Referring to some problems in the leather industry, she added:
The industry has not been given enough attention and support, and research in the field of the industry in the country has been very limited and inadequate.
She said that the leather industry is still traditionally managed,
considering that Iran has a comparative advantage in the leather industry and in the event of scientific and technological growth, Iran’s manufacturing of leather products can contribute to global markets, so research in the field of the industry is inevitable..
According to the Iranian researchers , genuine leather production with more capabilities, such as making genuine leather resistant against flame and accordance with global standards, are considered the priority research topics.
Ms. Samaneh Sepehri, emphasizing that this research has been a step towards improving the knowledge of genuine leather production, added ; since the process and materials of this research have been designed and selected to be similar to the current situation in Iranian leather factories, it can be said that this research has led to the localization of the technology to improve the resistance of genuine leather to the flames.
Also, using nanotechnology and the use of nanomaterial, the length of geniun leather burns reduced due to the resistance of leather to fire.
Referring to the “Improvement of genuine leather resistance to flame by adding clay nanoparticles,” she said; this research began with library and field research to find traditional and modern methods for producing anti-inflammatory leather.
Ms. Samaneh Sepehri continued: then knowledge of leather production in Iran was extracted from the factories and examined in the laboratory.
In the next step, the materials that create the fire resistance feature were added to the leather process. Finally, the effects of materials and processes on different leather properties were investigated and measured.
She stated that the result of this research is directly applicable in the leather industry, and then she added; the leather produced using the results of this research is being applied for in the furniture and automotive industry and aircraft manufacturing and clothing industry, in particular all kinds of work and safety apparel.
She added, Continuation of this project is a semi-industrialization of the product. It is also a continuation of research and study to further improve this feature or other complementary features of leather.
Referring to the characteristics of the results of the plan, she said: the use of natural leather that has unique properties.
Using Nano clay, which is abundant and low in price and has no environmental risks and the use of processes and chemicals that are commonly used in factories are considered the features of this design.
Graduated from Amir Kabir University of Technology said;
possibility of using the proposed method of design in leather factories without the cost of providing new machinery with very little change in the usual processes of the factories, the lack of knowledge or education, the absence of environmental pollution are some of the benefits of this project.
She mentioned; the product of this research can be used in the leather industry.
After mass production and completion of research, it can be used in industries such as automotive, airplane and apparel.
Professor Dr. Mohammad Amani Tehran and Dr. Fatemeh Zeighami have instructed this plan as the supervisor and advisor respectively.
Dr. Fatemeh Zeighami is one of the professors of Tehran University of Leather Applied Science.
Nanotechnology can play a key role in the production of new materials, Application of Nano Materials in the Shoe Industry.
In recent years, customers have increasingly grown their attention to a variety of dimensions, including comfort, security, health of the goods and more. At the same time, customers are interested in aesthetic aspects of shoes.
Therefore, the INESCOP shoe technology institute in Spain, using innovative technologies such as Nano Technology, has been working on developing advanced material to make shoe.
The use of new and multifunctional materials opens the way to different production methods in the shoe sector and allows manufacturers to meet both market needs and increase their competitive ability.
Nanotechnology can play a key role in the production of new materials that have mechanical and technical, lightweight, durable and anti-bacterial properties with excellent performance, and can satisfy customers.
Materials with Nanotechnology Structure
From this perspective, Nano-carbonates have become increasingly attractive materials, which, due to their unique structure and unique features, including high mechanical strength, provide manufacturers with innovative solutions.
In addition, Nano-carbonates can make tremendous changes, even if they are added to polymeric materials at a small scale.
In the same vein, researches have been conducted on the use of Nano carbon in shoes and in NANOFOOT project in Europe. The research focused on the shoe insoles.
For example, the goal was to use EVA microprocessors in the shoe insoles, which would eliminate the flow of electricity.
This causes the Static electricity flow to open its way out of the shoes. In addition, this method will make the shoes cool. Research in these areas has been successful so far.
Nano-carbon materials can also be used to produce polyurethane for these types of shoes.
Nanotechnology has made it possible to create shoes that antibacterial and antiphonal materials have been used in producing them. These materials prevent the growth of foot microorganisms that cause infection and bad smell.
To achieve this goal, research is being carried out on the use of metal nanoparticles, such as silver and gold, instead of organic biocides.
The antimicrobial of these materials that have been used for a long time are being used more than before. This has been achieved through the development of exploitative technology of Nano metric metal particles, and it has been proven that it can have great and long-lasting effects in confronting a wide range of bacteria.
The INESCOP Institute has used “green” synthesis methods for metallic nanoparticles. These experiments are carried out within the framework of the NANOMETAL project and are proposed as a substitute for current methods. With these methods, the quality and durability of the products are also higher.
Silica gel nanoparticles have a significant impact on the production of leather and shoes with antimicrobial properties as well as more quality and healthier glue for shoes.
In addition, nanoparticles have better capabilities when using 3D printing in the shoe and leather industry.
On the other hand, according to other researches and experiments, it is possible to create a combination of laser and plasma eco-friendly methods in the production of textiles and leather and to produce anti-fire, waterproof and anti-spot products. ..
Laser technology MLSE has helped to produce better materials without using hands and distorting the aesthetic aspects.
Controlled release of active substances such as antibacterial particles is an important issue in shoes. By using Nano-encapsulation technology this capability can be achieved.
The quality and durability of the goods can be improved by timely release of these particles. Nano capsules containing essential oils are embedded in the insoles and lining of the shoes and their material is purposefully and controlled transported directly to the foot when shoes are worn for long periods of time.
One of the problems in shoe technology and other industries is that in some products high temperature and mechanical pressures should be used to use Nano capsules.
Occasionally, high pressure and high temperatures allow Nano capsules to release the material sooner.
The INESCOP Institute has tried to solve this problem by making Nano capsules using organic materials such as metallic oxides, carbonates and silicates..
These organic materials act as a protective coating against heat and pressure, and prevent the early release of materials and particles. Using Nano-encapsulation technology in medical shoes and similar products, antibiotics and other materials and particles can be released at the right time and in the desired area.
Targeted and timely release of these particles improves their performance.
The INESCOP Institute in its other projects has also focused on the use of some polymer materials for medical purposes, as well as the pathology of shoe, to prevent foot infections.
Important point is that although the use of nanotechnology has the benefits in producing advanced materials, the final material should be such that in all aspects and in general terms, all aspects of safety and health are considered.
Therefore, the INESCOP Institute is investigating the human skin implanted cells in the laboratory environment. In this research, the possible effects of cytotoxic Nano materials on consuming goods technology are considered.
Also, the effects of environmental factors such as ultraviolet radiation or the ozone layer will also be investigated.
