Laboratorní zařízení pro přípravu spletených nanovlákenných přízí

Laboratory equipment for the preparation of braided nanofibrous yarns

Laboratory equipment capable of processing pure or composite nanofibrous yarns produced on the equipment offered by us. It allows their splicing also with yarns without nanofiber material to produce a functional unit that has the properties of nanofibrous material while maintaining the high tensile strength and abrasion resistance of conventional yarns. Its strength lies in processing a diverse range of materials, unlocking myriad application opportunities across medical and technical sectors.

Key features of the equipment

Uniqueness

The device is based on the worldwide unique technology for nanofibrous production using alternating current. This technology enables the creation of entirely innovative nanofibrous structures that can be modified by various other methods during the fabrication process, thus adding specific functional properties.

Reliability

The professional team of Nanotech dynamics has more than 12 years of experience in the technological development of worldwide unique devices and the production of a wide range of nanofibrous structures. This experience and careful selection of the most durable and highest-quality materials for structural and control elements guarantees the highest quality, even under high operating loads. Following that, we also offer technical support, service, and operator training as part of our services.

Simplicity

User-friendliness is ensured by the precise and simple setting of process parameters via a 15" touch panel and the easy interchangeability of the individual technological elements in the spinning chamber. All key components are easily accessible, making the equipment very simple to use, maintain and clean.

Flexibility

The equipment can be delivered in various variants and customised according to specific customer requirements and target applications. The spinning chamber allows for high modularity and flexibility in the arrangement of technological elements based on the needs of laboratory experiments or production processes. Another advantage is the possibility of advanced collection and interpretation of process data and measured parameters.

Safety

Safety is assured by the integration of a sophisticated control and monitoring system, a fire extinguishing system, the design of the equipment itself, and the low noise level in operation. The spinning chamber is sealed and fitted with safety locks, and the operation of the plant is indicated by warning lights. During the softening process, the monitoring and control system prevents users from entering the spinning chamber and interrupts the process if any anomaly is detected. The fire extinguishing system protects the users and the plant from fire and reacts immediately if ignition occurs in the spinning chamber.

Efficiency

The facility is capable of continuously spinning a wide range of biomedical and engineering polymers onto a variety of substrates for several application areas. The production process is set up so that efficient dosing of the polymer solution occurs, material losses are minimised, and the process consumes minimal energy.

TECHNICAL DOCUMENTATION

Areas of application of nanofibers

Air filtration

Due to their minimal diameters (on the order of nanometres), nanofibers have a high specific surface area and porosity, which means they can effectively trap very small particles and microorganisms. Using nanofibers in air filtration brings many benefits, including higher filtration efficiency at low-pressure gradients, longer filter life, and the ability to be applied in various environments. This allows air filtration systems to operate more energy efficiently. Specific application areas include filtration of particles, bacteria, and viruses, for example. Nanofibers are also used to manufacture personal protective equipment such as respirators and face masks, which protect the wearer against particles, microorganisms, bacteria and viruses.

Liquid filtration

The minimal diameter of the nanofibers and the high specific surface area ensure the effective trapping of particles and microorganisms in liquids. In liquid filtration, nanofibers are an innovative and effective way to achieve high filtration efficiency and improve product purity and safety in various industries. Nanofibrous structures are used to create filtration media to remove bacterial consortia and impurities from water, which is particularly important in areas with limited access to clean water. Other applications include the pharmacology for the filtration of pharmaceuticals, the food industry for the filtration of beverages such as wine and beer, and the filtration of food and technical oils and other liquids.

Functional textiles

Nanofibers are a very innovative material in the field of functional textiles and offer a wide range of possibilities to improve the available properties of textile materials. Incorporating a nanofibrous layer into clothing enhances breathability and well-being for the wearer and helps maintain body temperature and comfort. This is particularly important for sportswear and garments worn in hot conditions or for firefighters, police officers and other government forces. Nanofibers can also be enriched with substances with antibacterial properties, which help to prevent the growth of bacteria, odour, and mould. In addition to the above areas, nanofibers have found applications in several other innovative products that use these advanced materials.

Healthcare

Thanks to their biocompatibility, ability to interact with biological systems and favourable material properties, nanofibers are also widely used in healthcare. Medical devices with nanofibers have antibacterial properties, promote wound healing, and reduce inflammation. Nanofibers can also be used as sustained-release drug carriers, allowing precise and targeted drug delivery to specific body parts. Nanofibrous structures mimic the extracellular matrix and can thus be used to regenerate tissues and complicated wounds effectively. This is crucial, for example, in the healing of burns, complex wounds and tibial ulcers, where nanofibers are able to fully regenerate the patients’ injured tissue, ensuring effective treatment and, subsequently, a good quality of life.

Cosmetics

Thanks to their structure and ability to retain moisture and gradually release active ingredients, nanofibers can help hydrate the skin and improve the usability of a range of cosmetic products. Special nanofibers can be used to create thin-fitting masks that are saturated with moisturising and healing agents. These masks allow the skin to effectively absorb the beneficial ingredients, improve the effectiveness of skincare, and, thanks to their healing properties, help treat eczema and similar ailments. The nanofibrous structures can also be imparted with antibacterial properties to prevent skin infections. In addition to the areas mentioned above, nanofibers have found applications in a number of other innovative products that use these advanced materials.

Environment

Nanofibers play an important role in promoting sustainable development and addressing environmental challenges such as water, air and soil pollution and waste reduction. They can improve the mechanical, thermal, and other performance properties of materials, enabling the development of lighter and more durable structural materials that reduce the consumption of raw materials. Integrating nanofibers into recyclable materials and packaging increases the durability and shelf life of the packaged products. Nanofibers are used in cleaning technologies to remove specific pollutants, oil spills, and biological and chemical contaminants from contaminated soil, water, and air. Specially designed nanofibers can sorb toxic substances such as heavy metals, pesticides, or organic compounds.
