Shandong Rare Technology Development Co., Ltd. (Rare High-Tech) adopts a unique graphene nanophase change material (National Patent No. 202211637322.8). Using the conjugate hydrophobic end of an amphiphilic biomass dispersing and exfoliating agent to intercalate and exfoliate graphene, the hydrophilic end forms a high-purity graphene dispersion that remains stable for a long time with the solvent. Through independent solid-liquid mixing technology, uniform adsorption and efficient complexation between the graphene dispersion and cellulose substrates, PET (PA6) substrates are achieved, preparing high-quality multifunctional graphene-modified new materials for textiles with good biocompatibility and ultra-high thermal conductivity — Qimai® Graphene Superconducting Fiber/Yarn.

[Product Functions]

Tested by national authoritative testing institutions and verified by scientific practices, Qimai graphene products have excellent health-related properties such as far-infrared emission, ultra-high thermal conductivity, long-lasting antibacterial activity, antiviral activity, high-efficiency antistatic property, ultraviolet resistance, 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 over 90%.

2. Ultra-High Thermal Conductivity

Graphene is the material with the highest thermal conductivity discovered so far. Tests show that Qimai graphene has excellent thermal conductivity. Under the same heat source, its rapid temperature conduction ability is over 30% better than that of conventional materials. In a heat-preserving environment, body heat can be rapidly conducted and activated 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 Activity

Scientific research has found that when Escherichia coli and Staphylococcus aureus are exposed to graphene, the stress from the edges of graphene nanosheets can directly pierce the bacterial cell membranes, causing 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 powerful 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 antibacterial purposes. 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 they carry the risk of cytotoxicity that may harm 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 energy band structure and strong adsorption characteristics of Qimai graphene make it extremely easy to "capture" bacteria and viruses, possessing the active feature of "capture" + "elimination".

5. Ultraviolet Resistance

Ultraviolet radiation with a wavelength range of 290-400 nanometers will cause the skin to produce a large number of free radicals, leading to peroxidation of cell membranes and prompting melanocytes to produce more melanin. While effectively blocking ultraviolet rays, Qimai® Graphene Superconducting Fiber/Yarn can convert them into far-infrared rays, which not only protects the skin from sunburn and reduces the risk of skin cancer but also achieves health benefits.

6. Green Preparation

The preparation of Qimai® Graphene Superconducting Fiber/Yarn uses an amphiphilic biomass dispersing and exfoliating agent. Biotechnology is used 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, achieving green, healthy, low-carbon, and safe production.

[Application Fields]

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