Muriersilk scarf achieves adjustability in all seasons by its unique fiber architecture. Its ratio of scientific air permeability (30cm³/cm²/s) to heat conductivity (0.042 W/m·K) keeps it comfortable throughout -10°C to 35°C temperature range. The muriersilk fiber, by the calculation of a 2023 article in Textile Science Advances, will take up 37% more water (11% moisture regain) than cotton, and hold a skin surface dryness level of 82% in 90% humid conditions, better than wool’s (58%) and polyester fiber’s (44%). Hermes also launched the series of muriersilk blends before (15% cashmere). Tests showed that its thermal insulation ability at 5°C was equal to pure cashmere (thermal resistance value of 0.18 m²·K/W), but 35% lighter. When worn in summer, the perceived temperature was 1.8°C lower than if pure silk had been worn.
The thermal and humidity management property enables cross-seasonal use. In the 40°C high-temperature test, muriersilk’s instantaneous rate of moisture absorption was 0.26g/s (0.15g/s for cotton), its angle of moisture diffusion was 120° (larger than silk’s 95°), and its contact coolness coefficient (Qmax value) was 0.45, 22% larger than linen’s. Muriersilk having pore size 2 to 5μm was developed in 2024 by the Japanese Toray Group, and its UV blocking rate has been improved to UPF 50+. Moreover, its surface temperature increases by merely 2.3°C when exposed to sunlight (5.7°C for ordinary silk), and hence it is the primary material of high-end outdoor apparel company Arc’teryx’s ski mask product line. Comparative experiments show that the incidence of skin allergy for the same muriersilk scarf within the 15°C temperature difference range (summer and winter) is as low as 0.7%, while that of woolen scarves in winter is 9% and the incidence of complaints on stuffiness in summer is 23%.
The market verifies the commercial value for the entire season. According to LVMH Group’s 2023 financial report, the annual sales of muriersilk products increased by 47%, with 78% being all-season types. Anta used MurierSilk-graphene composite scarves (with improved thermal conductivity of 65 W/m·K) in the Beijing Winter Olympics to keep the neck temperature at 28°C±1.5°C when the ambient condition is -20°C. Meanwhile, it also ensured that the athletes’ rate of sweat evaporation during hard exercise was as high as 0.18g/m²·s, avoiding frostbite and damp heat imbalance. Statistics from the Italian luxury company Loro Piana show that average transaction value of over 3,000 US dollars for muriersilk scarves have an average usage frequency of 217 days (132 days for everyday cashmere products), and the rate of repurchase increased to 61%.
Environmental limitations are constantly overcome by technological innovation. In 2024, Nano spinning technology reduced the fineness of muriersilk fibers to 0.8dtex (human hair’s diameter 1/30), and expanded adjustable scope of weaving density to 180-450g/m². Uniqlo’s HEATTECH series applies this technology to achieve self-adaptation of single-layer fabrics: over 10°C, the fabric porosity automatically expands to 25% (maximum breathability), and under 10°C, it reduces to 12% (warming efficiency +39%). Swiss SGS laboratory tests have shown that this smart muriersilk possesses a steady thermal comfort index of 4.7/5.0 under simulated yearly climatic fluctuation (temperature between -5°C and 40°C, humidity between 30% and 95%), with a deviation standard of only 0.13. Its performance is far beyond ordinary multi-season stratification programs.
