Shandong Rare Technology Development Co., Ltd. (Rare High-Tech) uses unique graphene nano-phase change materials (national patent No. 202211637322.8), and uses the conjugate hydrophobic end of amphiphilic biomass dispersing and stripping agent to intercalate and strip graphene. The hydrophilic end forms a high-purity graphene dispersion liquid that is stable for a long time with the solvent. Through independent solid-liquid mixing technology, uniform adsorption and efficient complexation between the graphene dispersion liquid and cellulose substrates and PET (PA6) substrates are realized, and a high-quality multifunctional graphene modified new material for textiles with good biocompatibility and ultra-high thermal conductivity is prepared — 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, high-efficiency antistatic, anti-ultraviolet, and green preparation.

1. Far-infrared Emission

At a low temperature of 25-35℃, graphene has excellent normal emission and absorption-promoting effects on far-infrared rays with a wavelength of 6-14μm. This band of far-infrared rays is known as "life light waves" by scientists and can assist in promoting microcirculation. Tested by a national professional testing institution, 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 found 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 heat-preserving environment, body heat can be rapidly conducted and stimulated through graphene fiber materials, forming a "heat storage cabin" warming effect; in an open environment, body heat can be rapidly 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 nano-sheets of graphene's layered structure can directly puncture 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, preventing bacteria from reproducing 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 decrease after multiple washes.

4. Antiviral Activity

Traditional antiviral materials such as metal materials, chemical drugs, high temperature, and ultraviolet irradiation can inactivate viruses, but they have the risk of cytotoxicity and harm to the human body. Graphene's unique nano-scale 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 energy band structure and strong adsorption characteristics of Qimai graphene make it extremely easy to "capture" bacteria and viruses, with the active characteristics of "capture" + "kill".

5. Anti-ultraviolet

Ultraviolet radiation 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. While effectively blocking ultraviolet rays, Qimai® Graphene Superconducting Fiber/Yarn also converts them into far-infrared rays, which not only protects the skin from sunburn and reduces the risk of skin cancer, but also achieves the purpose of health benefits.

6. Green Preparation

Qimai® Graphene Superconducting Fiber/Yarn uses amphiphilic biomass dispersing and stripping agent in its preparation, and uses biotechnology instead of chemical agents to solve the problems of graphene sheet 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.
