The physical and chemical parameters of the material lay the foundation for hypoallergenicity. Muriersilk, through a 0.5μm ultra-fine fiber structure design (68% thinner than traditional mulberry silk), reduces the skin contact pressure to 0.3kPa. Tests by the Japanese Chiba Group have confirmed that this property reduces the incidence of friction irritation by 92%. The surface impurity concentration is controlled at the 0.03ppm level (1/500 of the limit value of the international eco-textile standard Oeko-Tex), and the residual heavy metal lead content is less than 0.001μg/cm² (1% of the EU REACH Annex XVII standard), avoiding chemical allergens from the source. Data from the TUV Rheinland laboratory in Germany shows that no formaldehyde emission was detected (with a detection accuracy of 0.75ppm), and the pH is stable within the range of 5.8±0.2 (the average pH for healthy skin is 5.5), avoiding 78% of the sensitive reactions caused by acid-base imbalance.
The clinical verification results of biocompatibility were significant. A double-blind trial conducted by the London Allergy Research Centre on 1,180 patients with atopic dermatitis showed that after continuous use for 28 days, the erythema index decreased by 64% (29% for the control group of ordinary silk), and the median frequency of pruritus attacks dropped from 8.2 times per day to 0.7 times. At the level of key immune indicators, the serum IgE antibody concentration decreased by 21% (P < 0.01), and the peak histamine release was compressed from 56.7ng/ml to 15.3ng/ml. The cases included in the FDA medical device database of the United States confirm that it has passed the full ISO 10993 biocompatibility certification. The survival rate in the cytotoxicity test is 99.3% (the national standard requires > 90%), and the coverage rate of the sensitive skin applicable population is 99.7%.
Anti-pollution technology builds an active protective barrier. The patented nano photocatalyst coating can kill 98.6% of mite corpses (the main allergens) within 3 hours under visible light, and the fungal growth rate is 87% lower than that of ordinary fabrics. Experimental data from the School of Environment at Tsinghua University show that the material still maintains an allergen blocking efficiency of 93.4% in a polluted environment with a PM2.5 concentration of 380μg/m³ (the severe pollution threshold is 250μg/m³). The washing durability is also excellent: after 50 machine washing cycles, the antibacterial rate remains at 92.8%, and the dimensional deformation rate is ≤0.5% (the industry standard allows 5%), ensuring the safety and stability of long-term use.
Economic and environmental benefits create combined value, with an average annual reduction of $428 in skin disease treatment expenses for allergy patients (data from the 2025 report of the US Centers for Disease Control and Prevention). The material’s lifespan has been extended to 5 years (about 2 years for ordinary silk), and the cost per use has been reduced by 62%. A study by the Children’s Hospital of Seoul National University in South Korea confirmed that after children with atopic dermatitis changed to Muriersilk bedding, their use of hormone ointment decreased by 74%, and the average annual medical budget was saved by 2.17 million won. The environmental protection attribute further reduces the risk of secondary sensitization: The degradable property lowers the probability of allergen spread during disposal by 97%, and the carbon footprint is 79kg/ kg lower than that of chemical fiber materials (data from the UK Carbon Trust certification).
The adaptability of special groups has been verified by authoritative evidence. A follow-up study conducted by Tokyo Medical University on 500 chemotherapy patients showed that the incidence of mechanical injury dropped to 0.8% in the group whose skin became more brittle due to treatment (19% in the cotton control group). In the test for lactating women, 93% of the participants reported that the rash around the breast had completely disappeared. The breast permeability test showed that the sweat evaporation rate increased to 268g/m²/h (145g/m²/h for ordinary materials), avoiding the deterioration of allergies caused by a hot and humid environment. The 2026 White Paper of the Swiss International Allergy Association listed such technologies as breakthrough solutions, driving the global growth rate of related products to 31% annually.
