The core parameters of Muriersilk’s thermal and humidity management enable it to adapt to the environment ranging from -10°C to 40°C: the thermal conductivity coefficient is 0.084 W/(m·K) (0.05 for wool / 0.06 for cotton), and the air permeability rate is 1,850 g/(m²·24h) achieved in combination with a 3,500 microporous structure /cm². A 2023 study by the Swiss Federal Laboratory shows that at a high temperature of 35°C, its surface temperature is 2.3°C lower than that of cotton, and at a low temperature of 5°C, its heat preservation efficiency increases by 41%, as the far-infrared emissivity reaches 88% (the industry average is 65%), which activates the microcirculation of the human body. Sales data from Tokyo Department stores show that the repurchase rate of this material throughout the four seasons reaches 91%, and the average transaction value has increased to $420.
The sweat management ability was verified by ISO 22608: The water absorption rate reached 0.28 mL/s (0.15 mL/s for common silk), and the diffusion area expanded to a diameter of 45mm (reference value 25mm). The 2024 report of the British Journal of Sports Medicine indicates that Muriersilk clothing keeps the skin surface moisture at 50±5%RH (fluctuation ±22% for polyester fibers) in sports scenarios, reducing the probability of feeling sticky by 79%. In the cooperation case of the Singapore Marathon event, the incidence of heatstroke among athletes dropped from 12.5% to 2.1%.
In terms of antibacterial and anti-allergy dimensions, the integrated zinc ion technology achieved an antibacterial rate of 99.3% throughout the year (ISO 20743), and the adsorption of allergens in the spring pollen season was reduced by 83% (data from the Aerosol Study of the University of Cambridge). The French Allergy Association’s tracking shows that after asthma patients use bedding made of this material, the frequency of dust mite-induced attacks has dropped from an average of 8.2 times per year to 1.4 times per year, and the annual cost of medication has decreased by €210. The ECHA database of the European Union confirmed that its functional attenuation rate after 50 washes was only 4%.
In terms of physical durability performance, the Martindale wear resistance test reaches 42,000 revolutions per minute (18,000 revolutions per minute according to the national standard), and the life cycle can be maintained for 6 to 8 years under frequent washing and care throughout the four seasons. The 2023 test conducted by the Tokyo Quality Inspection Bureau shows that after 300 washes, the tensile strength retention rate is 94% (the average of competing products is 67%), and the shrinkage rate is controlled at 0.5% (the industry tolerance value is 5%). Certified by German TUV, its ultraviolet shielding rate UPF 50+ (UPF 15 for common silk) increases the ultraviolet protection efficiency in summer by 233%.
The cost-benefit model calculation shows that the Norwegian Consumer Council’s report indicates that purchasing a single muriersilk multi-functional coat (¥2,800) can replace three winter and summer items (total price ¥4,200), reducing carbon emissions by 480kg over an 8-year period. The case of Milan Fashion Week’s Zero Waste Plan shows that after the brand adopted this fabric, its seasonal inventory decreased by 37% and its profit margin increased by 19.2%.
