Shandong Xiyou Technology Development Co., Ltd. (Xiyou High-Tech) utilizes a unique graphene nano-phase change material (National Patent No. 202211637322.8). By employing an amphiphilic biomass dispersing and exfoliating agent, the conjugated hydrophobic end intercalates and exfoliates graphene, while the hydrophilic end forms a long-term stable, high-purity graphene dispersion with the solvent. Through proprietary solid-liquid mixing technology, the graphene dispersion achieves uniform adsorption and efficient complexation with cellulose-based and PET (PA6) substrates, resulting in the development of a high-quality multifunctional graphene-modified new material for textiles—Qimai? Graphene Superconducting Fiber/Yarn—which exhibits excellent biocompatibility and ultra-high thermal conductivity.

【Product Functions】

Tested by national authoritative testing institutions and validated through scientific practice, Qimai graphene products exhibit excellent health properties, including far-infrared emission, ultra-high thermal conductivity, long-lasting antibacterial effects, antiviral activity, efficient antistatic performance, UV resistance, and green manufacturing.

1. Far-Infrared Emission

At low temperatures of 25-35°C, graphene exhibits excellent normal emissivity and promotes absorption of far-infrared rays with wavelengths of 6-14μm. This wavelength range is hailed by scientists as the "life light wave" for its ability to assist in promoting microcirculation. Tested by national professional testing agencies, the far-infrared normal emissivity of Qimai? Graphene Superconducting Fiber/Yarn can reach over 90%.

2. Ultra-High Thermal Conductivity

Graphene has the highest thermal conductivity of any known material. Tests show that Qimai graphene possesses excellent thermal conduction properties. Under the same heat source, its temperature conduction capability is over 30% better than conventional materials. In insulated environments, body heat can be rapidly conducted and stimulated through graphene fiber materials, creating a "heat storage cabin" warming effect. In open environments, body heat can be quickly dissipated through the fiber material, forming a "radiator" effect. Qimai? Graphene Superconducting Fiber/Yarn is an excellent "bidirectional temperature-regulating" material.

3. Long-Lasting Antibacterial Effect

Scientific research has found that when E. coli and Staphylococcus aureus are exposed to graphene, the stress at the edges of graphene’s layered nanosheets can directly pierce bacterial cell membranes, causing leakage of internal RNA (ribonucleic acid) and leading to bacterial death. Additionally, due to graphene’s large specific surface area and strong adsorption capacity, it can adsorb phospholipids—a key component of cell walls—preventing normal bacterial reproduction. Meanwhile, the powerful far-infrared effect of Qimai graphene assists in promoting microcirculation, 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 diminish after multiple washes.

4. Antiviral Activity

Traditional antiviral materials such as metals, chemical drugs, high temperatures, and UV irradiation can inactivate viruses but carry risks of cytotoxicity and harm to the human body. Graphene’s unique nano-scale edges, large specific surface area, surface functional groups, and photothermal catalytic effects provide broad-spectrum antibacterial properties and effective virus "inactivation" capabilities. Moreover, Qimai graphene’s special energy band structure and strong adsorption characteristics make it highly effective at "capturing" bacteria and viruses, exhibiting an active "capture + kill" mechanism.

5. UV Resistance

UV radiation in the wavelength range of 290-400 nanometers causes the skin to produce large amounts of free radicals, leading to peroxidation of cell membranes and stimulating melanocytes to produce more melanin. Qimai? Graphene Superconducting Fiber/Yarn not only effectively blocks UV rays but also converts them into far-infrared radiation. This not only protects the skin from sunburn and reduces the risk of skin cancer but also promotes health benefits.

6. Green Manufacturing

The production of Qimai? Graphene Superconducting Fiber/Yarn utilizes amphiphilic biomass dispersing and exfoliating agents, employing biotechnology to replace chemical agents. This approach resolves issues of graphene sheet agglomeration and performance instability during processing. While significantly improving product quality and functionality, it reduces resource consumption, achieving green, healthy, low-carbon, and safe production.

【Application Fields】

Qimai? Graphene Superconducting Fiber/Yarn is widely used in special equipment, aerospace gear, outdoor equipment, sportswear, intimate apparel, home textiles, hygiene products, protective gear, cosmetics, functional braces, and other product fields.
