Application of nanomaterials in clothing
Application of nanomaterials in clothing
Abstract: With the development of science and technology, nanotechnology has been widely used in many fields, including ceramic materials, optical materials, medical materials, textile materials, clothing, etc. This article explains the main applications and principles of nanotechnology in clothing; nanotechnology and new clothing fabrics. Nanomaterials refer to materials in which at least one dimension in three-dimensional space is at nanometer size (0.1-100nm) or composed of them as basic units, which is approximately equivalent to a scale where 10 to 100 atoms are closely arranged together.
Nanomaterials refer to materials in which at least one dimension in three-dimensional space is at nanometer size (0.1-100nm) or composed of them as basic units, which is approximately equivalent to a scale where 10 to 100 atoms are closely arranged together. Nanotechnology is another major discovery in the process of human society’s understanding of matter. Nanotechnology has immeasurable potential. Some people say that it will even surpass computers and genetic medicine and become the decisive technology of the 21st century. However, after all, nanotechnology is a new technology that has only flourished in the past two decades. Our understanding of it is still very superficial. The application of nanotechnology in our country is still in the development and experimental stage, and there is still a certain distance between industrialization and large-scale entry into the market. . However, it can be predicted that with the in-depth research and development of nanotechnology, its application in textile products will become more and more extensive in many high-tech fields, and its positive role in the development of textile products will be immeasurable.
1.0 Main applications of nanotechnology in clothing
Since the 20th century, nanotechnology has been used in clothing and clothing. It was not until the beginning of the 21st century that people initially realized the role of nanotechnology in clothing. The main application of nanotechnology in clothing is the “three defenses” – waterproof, oil-proof, and anti-fouling. No matter whether it is drinks, seasonings, cooking oil, dust, etc., they cannot easily penetrate and stain the fabric; the fabric has the property of not being polluted. , it is not easy to penetrate stains, so it can extend the washing interval, shorten the time for washing fabrics, and reduce the cost of cleaning supplies; due to its super amphiphobic properties, the fabrics are more quick-drying; the fabrics are environmentally friendly, pollution-free, and non-toxic. At present, the three-proof effect of almost all nano-clothing and clothing is to cover some kind of nano-scale particles on the fiber surface or embedded in the fiber or even the molecular gap. Since the particles are very small (less than 100rim) and have a large surface area, Can be high. A uniform, extremely thin “aerosol-like” protective layer with extremely thin thickness (cannot be observed with the naked eye or felt by hand) and extremely small gap (less than 100rim) is formed on the surface of the material. It is precisely because of the existence of this protective layer that it is difficult for water droplets, oil droplets, dust, stains and even bacteria with a size much larger than 100nm at room temperature to enter the interior of the fabric and can only stay on the surface of the fabric, resulting in special features such as three-proof Effect. Just like a lotus leaf, water droplets roll on the lotus leaf, but the lotus leaf is not soaked. When water hits the fabric, it forms water beads on the air cushion and rolls away from the fabric. If moisture penetrates the fabric under pressure, the moisture will not be absorbed by the fabric. Therefore, when sweating, the sweat can use the capillary wicking effect to be discharged from the body through the fabric, keeping it dry and water-repellent. At the same time, because the nano-sized particles that form the protective layer are extremely small, they will not change the physical properties of the original gray fabric, such as color, comfort, breathability, etc. Nanotechnology processing requires a certain amount of cost and is generally used on high-value or special products, such as suits, shirts, ties, underwear, etc. As early as 2003, “Ordos” invested heavily in nanotechnology and successfully applied a new type of nanomaterial that is non-stick to oil stains to cashmere products, giving the originally ordinary cashmere products magical “three-proof” and self-cleaning functions. .
2.0 Nanotechnology and New Clothing Fabrics
Nanoparticles have many special properties. By combining them with clothing materials, new clothing fabrics can be prepared with functions such as anti-bacterial deodorization, anti-ultraviolet, infrared absorption, anti-aging, anti-electromagnetic radiation, anti-static, self-cleaning and other functions; Nano The fiber has the characteristics of soft hand, soft luster, high water and oil absorption, etc., and can weave clothing fabrics with good simulation and good performance.
There are two main types of clothing fabrics produced using nanotechnology and nanomaterials: one is adding nanoparticles to textile materials to modify chemical fibers or fabrics to produce functional fabrics, such as antibacterial, deodorant, and UV protection. , cool, anti-electromagnetic radiation, health care, heat storage and insulation, anti-static, stealth, anti-aging, wash-free and other fabrics; the other type is high-functional fabrics made of nanofibers produced by special spinning methods and weaved and finished, such as : Imitation silk, imitation peach skin, imitation suede and artificial leather, waterproof and breathable, high warmth, high moisture absorption, low resistance and other fabrics. Nano clothing fabrics achieve “supernatural” effects. Its simulation effect is more realistic; it has more functions, is stronger and more durable; it is more perceptual and closer to human requirements. Clothes made of nano fabrics can better meet the design requirements of fashion, high-end, diversification and personalization. In short, the application of nanotechnology and nanomaterials to develop new fabrics is a new direction for the development of clothing fabrics.
Antibacterial and deodorizing fabric. In addition to preventing, inhibiting or killing bacteria, antibacterial and deodorizing fabrics can also eliminate toxins and odors secreted by bacteria. Antibacterial and deodorizing fabrics that appeared in the early 1980s were mostly used for�dimensional.
