山东 Rare Science and Technology Development Co., Ltd. (Rare High-Tech) uses unique graphene nanophase change material (national patent 202211637322.8), and uses the conjugate hydrophobic end of amphiphilic biomass dispersion exfoliant to intercalate and exfoliate graphene. The hydrophilic end forms a long-term stable high-purity graphene dispersion with the solvent. Through independent solid-liquid mixing technology, it realizes uniform adsorption and efficient complexation between graphene dispersion and cellulose substrate, PET (PA6) substrate, and prepares a high-quality multifunctional graphene modified new material for textiles with good biocompatibility and ultra-high thermal conductivity——Qimai® Graphene Superconducting Fiber/Yarn.

【Product Functions】

Tested by national authoritative testing institutions and feedback from scientific practices, Qimai graphene products have excellent health characteristics such as far-infrared emission, ultra-high thermal conductivity, long-lasting antibacterial, antiviral activity, efficient antistatic, UV protection, and green preparation.

1. Far-infrared emission

At low temperatures of 25-35℃, graphene has excellent normal emission and absorption promotion effects on far-infrared rays with a wavelength of 6-14μm. This band of far-infrared rays is known by scientists as the "life light wave", which can assist in promoting microcirculation; tested by national professional testing institutions, the normal emissivity of far-infrared rays of Qimai® Graphene Superconducting Fiber/Yarn can reach more than 90%.

2. Ultra-high thermal conductivity

Graphene is the material with the highest thermal conductivity so far. Tests show that Qimai graphene has excellent thermal conductivity. Under the same heat source, its rapid temperature conduction ability is more than 30% better than that of conventional materials. In a warm environment, body heat can be quickly conducted and stimulated through graphene fiber materials, forming a "heat storage cabin" warming effect; in an open environment, body heat can be quickly dissipated through fiber materials, forming a "radiator" effect. Qimai® Graphene Superconducting Fiber/Yarn is an excellent "two-way temperature regulation" material.

3. Long-lasting antibacterial

Scientific research has found that when Escherichia coli and Staphylococcus aureus are exposed to graphene, the stress on the edges of the nanosheets of graphene's layered structure can directly pierce the bacterial cell membrane, causing the leakage of internal RNA (ribonucleic acid) and leading to bacterial death. In addition, due to graphene's large specific surface area and strong adsorption capacity, it can adsemble phospholipids, a component of cell walls, making it impossible for bacteria to reproduce normally. At the same time, the strong far-infrared effect of Qimai graphene can assist in promoting microcirculation, thereby activating skin immune cells and enhancing the phagocytic function of white blood cells and reticuloendothelial cells to achieve the antibacterial purpose. The antibacterial effect does not attenuate after multiple washes.

4. Antiviral activity

Traditional antiviral materials such as metal materials, chemical drugs, high temperature, and ultraviolet irradiation can inactivate viruses, but there is a risk of cell toxicity causing harm to the human body; graphene's unique nanoscale edges, large specific surface area, surface functional groups, and photothermal catalytic effect bring broad-spectrum antibacterial and bacteriostatic properties and the ability to effectively "inactivate" viruses. Moreover, the special band structure and strong adsorption characteristics of Qimai graphene make it extremely easy to "capture" bacteria and viruses, with the active characteristics of "capture" + "elimination".

5. UV protection

Ultraviolet rays with a wavelength range of 290-400 nanometers will cause a large number of free radicals in the skin, leading to peroxidation of cell membranes and making melanocytes produce more melanin; Qimai® Graphene Superconducting Fiber/Yarn can effectively block ultraviolet rays and convert them into far-infrared rays at the same time. It can not only protect the skin from sunburn and reduce the risk of skin cancer, but also achieve the purpose of health benefits.

6. Green preparation

The preparation of Qimai® Graphene Superconducting Fiber/Yarn uses amphiphilic biomass dispersion exfoliant, and uses biotechnology instead of chemical agents to solve the problems of graphene sheet layer agglomeration and unstable performance during processing. While greatly improving product quality and functions, it reduces the consumption of production resources, realizing green, healthy, low-carbon and safe production.

【Application Fields】

Qimai® Graphene Superconducting Fiber/Yarn is widely used in special equipment, aerospace equipment, outdoor equipment, sportswear, close-fitting underwear, home textiles, sanitary products, protective products, beauty products, functional protective gear and other product fields.
