Application of nanotechnology in the finishing of embroidered wall coverings
In the eyes of most people, nanomaterials may still be a very technical material and there is still some distance from our lives. However, in real life, nanotechnology has a wide range of uses, and nanomaterials are not far away from us.
With the rise and continuous development of information technology and bio-engineering, nano-functional materials and nano-technology have become the focus of research in various countries. Due to the unique structure and performance of nanomaterials and the wide application prospects in practice, nanotechnology has penetrated into every aspect of human life and production, such as cosmetics, paints, and foods in life, as well as machinery, electronics, and chemicals. , medicine, energy, etc. Nanotechnology can make many traditional products improve or acquire a series of new features and enhance the market competitiveness of products.
In the textile industry, nanomaterials and technologies also have a very broad prospect of use, especially in the functionalization of textiles and high value-added today, nanomaterials can obtain conductive static, high-strength and wear-resistant through the functionalization of raw materials and finishing methods. Antibacterial deodorant, anti-ultraviolet radiation, high adsorption and other functions.
First, the application of nanomaterials in textiles can be divided into two major categories. First, it is achieved through the functional modification of fibers, and the second is the functional finishing of fabrics through finishing technology.
Nanomaterials are used in the functionalization of fiber modification, mainly using chemical fiber modification technology, and nanomaterials are used as additives to modify the fibers to prepare functional fiber/nanomaterial composite fibers. For example, the solution blending in the wet spinning is to dissolve the polymer into a suitable solvent, add the nanoparticles into the mixture, stir it well, and then perform the spinning process, and the melt spinning is adding the nanoparticles to the In the molten polymer, functionalized fibers are prepared. This method utilizes the thermal stability of the nanoparticles, but requires good dispersion and compatibility with the polymer.
Finishing is also a method of combining the main nanoparticles with textiles, especially for natural fibers. This method mainly refers to the coating method and the impregnation method. The coating technology is a commonly used technique in finishing, which is to add nanoparticles into the coating agent and then finely coat it on the surface of the fabric. After drying and some necessary treatments, a functional coating is formed on the surface of the fabric, so that special functions can be achieved. This method is simple and durable, and has the advantages of convenient operation and the like. The impregnation method is to mix the nano-particle latex and other finishing agent into a uniform manner, and dip the fabric into a special effect. In a word, how the nanoparticles combine better with textiles is mainly to solve the two problems: how to make them evenly distributed in textiles or fibers, and how to make them well-integrated with fiber polymers and fabrics. To ensure product quality stability, durability and uniformity. 
Second, nanomaterials also have a wide range of applications in textile functionalization.
With the application of various high and new technologies in the textile processing industry and people’s needs for comfort, hygiene, health care and other aspects, various functional textiles have emerged continuously, such as antibacterial, odor, UV, far infrared, and electromagnetic radiation. Antistatic and so on, specific to nanotechnology and nanomaterials, can be used mainly in the following aspects
1, anti-UV, anti-static finishing and far infrared health care
Ultraviolet light has the function of sterilization, but for the human body, excessive irradiation of ultraviolet light induces various types of skin diseases, promotes cataracts and other eye diseases, and reduces immunity, especially in the continuous destruction of the atmospheric ozone layer, and the amount of ultraviolet radiation on the ground. Rapid increase, it is necessary to carry out anti-ultraviolet finishing of textiles. Some nano-particles have the ability to absorb and reflect ultraviolet rays, such as nano-zinc oxide powder that has this property, can effectively prevent skin erythema, prevent skin cancer and other diseases.
2, antibacterial, anti-electromagnetic radiation finishing
Some metal particles, such as silver, copper, zinc, iron, etc., can release a trace of metal ions and combine with negatively charged bacterial proteins to deform or precipitate bacteria, thereby achieving bactericidal action. At present, the commonly used textile antibacterial agents at home and abroad are mainly divided into organic antibacterial agents and silver series inorganic antibacterial agents. Among them, organic antibacterial agents have unidirectional antibacterial properties, which can easily cause bacterial resistance, and silver series inorganic antibacterial agents have high costs. And the preparation process is complicated. The nano zinc oxide and silver oxide powders not only have good antibacterial and deodorizing functions, but also have a good UV shielding effect.
3, the production of sun-resistant, anti-aging, high-strength wear-resistant materials
Some chemical fibers are not resistant to sun exposure because organic polymer materials are degraded by ultraviolet radiation and generate a large amount of free radicals, which affects the color and strength of fibers and textiles. Nano-sized TiO2 particles are A kind of stable UV absorber can be uniformly dispersed in the polymer material, and the absorption of ultraviolet rays can be used to prevent the degradation of the molecular chain, so as to achieve the anti-aging and anti-aging effect.
In addition, carbon nanotubes also have good wave-absorbing properties. Fabrics made from fibers containing their microparticles have much higher light absorption than conventional absorbent materials and can be used to make wave-absorbing anti-reflection fabrics for special applications.
The fabric made of nanomaterials may be said to be the closest to our lives. Nanotechnology is a chemical processing technology based on nanomaterials. Nanofabric uses a special physical and chemical processing technology to integrate nanomaterials into fabric fibers to form a protective layer on common fabrics to increase and enhance the waterproof and anti-fabric properties of fabrics. Oil, antifouling, breathable, bacteriostasis, environmental protection, color fixing and other functions can be widely used in clothing, home textiles and industrial textiles.
