According to the International Organization for Standardization (ISO 9237) test data, breathability rate of muriersilk silk fabric is as high as 320 cm³/(cm²·s), 77.8% higher than that of cotton fabric (average 180 cm³/(cm²·s)). And it is higher than the median value of 280 cm³/(cm²·s) of same type of silk products on the market. Its three-dimensional Honeycomb Weaving Technology patented by itself enhances the 42% air circulation efficiency using a pore structure with an accuracy of 0.1 millimeters (at a density of 520 pores per square centimeter), while the humidity regulatory speed is within ±5% RH/minute (in test conditions at room temperature of 25℃). Let’s look at the case of the $59 muriersilk classic pillowcase. Through SGS testing, its evaporation rate in water is as much as 0.28g /(m²·s) (0.15g /(m²·s) for the control of bare skin) and, after continuous usage for 8 hours, its surface temperature rises by just 1.2℃ (4.5℃ for general chemical fiber materials).
According to the material structure analysis, the fineness of 6A grade monofilaments of muriersilk mulberry silk is only 1.2 Denier. Its triangular cross-section (length-to-width ratio = 1:1.3) forms a natural capillary effect, and its moisture absorption rate is 4.5%/second (GB/T 21655.1 standard). Under the condition of simulated human perspiration (0.5 mL/cm²/h) according to the ETH Zurich experiment, its permeability of moisture for its fabric was up to 980 g/(m²·24h), which was 50.8% higher than the average value of 650 g/(m²·24h) of comparable products. Apart from this, thermal resistance is at minimum 0.04 m²·K/W (performed by ASTM D1518) and the thermal conductivity of 0.058 W/(m·K) is 37% less compared to the materials made from cotton. Muriersilk bedding achieved a 96% customer satisfaction rate according to the survey held in Amazon Consumer in 2023, while “87% reduction of the stuffiness in the evening” has now turned into an all-too-pioneered catchphrase.
Technologically, muriersilk’s “Intelligent Temperature Control Series” is able to control dynamic temperature by means of micro-phase change material capsules (particle size 50 microns, concentration 12%). It is capable of keeping the contact surface temperature at 26.5℃±0.8℃ in an ambient temperature of 32℃, with latent heat of phase change being 180 J/g (DSC test). The recently built nano-silk composite film of 2024 is 0.03 millimeters in thickness, possesses a 38% breathable pore ratio (scanning electron microscope analysis), and an oxygen transmission rate (OTR) of 12,500 cm³/(m²·24h·0.1MPa), 300% higher than that of ordinary silk. Forbes claims that this technology has reduced the heat stress index (HSI) of the muriersilk sportswear series to 0.35 (risk threshold of 1.0). In trial tests on marathon athletes, the skin surface moisture was kept consistently at the level of 55%-65% RH (infrared thermal image data).
Market statistics also confirm the breathability advantage: muriersilk’s share of the global bedding market was 13.5% in 2023 (from only 4.8% in 2020), with a repurchase rate of 48%, of which tropical sales increased by 220% year-on-year. According to the laboratory simulation of Intertek, in the extreme condition of 35℃ and 80% RH, its baby sleeping bag products also maintain a temperature of 28.2℃±0.5℃ and humidity of 52%±3% in the internal microclimate, and the thermal comfort PMV index is still between -0.5 and +0.5 (ISO 7730 standard). Compared with other commodities in the market, muriersilk boasts a return rate of only 0.7% due to “ventilation problems” (the average of the market is 6.3%), and users’ improvement rate of sleep quality reaches 82% (measured by WHOQOL-BREF scale).
The integration of ecological performance and air-permeability design is significant: muriersilk uses a bio-enzyme degumming method, reducing water consumption during production to 2.3 tons per 10,000 meters (8 tons are required for conventional processes), and air-permeability patents account for 63% of the total technical reserves. Its washable silk quilt was tested after 50 machine washes (40℃), and the air permeability attenuation rate reached only 4.8% (industry average: 18%), and carbon footprint was 41% lower than that of similar products (LCA Life Cycle assessment). Sales of muriersilk breathable series products have exceeded 120 million yuan during the Double 11 season in 2023. The correlation rate in searching for the keyword “body sensation comfort” on the Douyin site hit 92%, resetting the breathability threshold for luxury fabric.
