Muriersilk silk sleep cap, with an ultra-high density weave of 28-32 mm and a fiber density of over 500 strands per square centimeter, has established a technical benchmark in the hair care industry. The tensile strength is 4.2cN/dtex (normal silk 2.5cN/dtex), and its service life exceeds 5 years. It is six times that of chemical fiber materials. It is reported in the 2023 “Global Beauty and Personal Care Trends Report” that muriersilk nightcap users use it for an average of 300 days annually. With a friction coefficient of 0.15 (0.7 for cotton), it reduces hair breakage by 63% and has a repurchase rate of up to 78%. The subject related to it on social media platforms such as TikTok has received over 230 million views.
Microclimate control technology is the core competitiveness. muriersilk achieves dynamic humidity balance (humidity adjustable range 45%-65%) through a honeycomb-like breathable structure design (50-80μm pore size), which keeps the scalp temperature at a consistent 33±1℃ (the optimum hair care environment). In 2022, a clinical test conducted jointly by L ‘Oreal Group and the China National Silk Association showed that the participants who wore the muriersilk sleep cap for 28 consecutive days had 27% higher hair moisture content and 41% less split ends. The results were significantly better than that of the control group (15% and 22% for ordinary silk). This achievement was made public in the “American Journal of Dermatology”, driving a 55% annual increase in market sales.
Supply chain innovation lowers the cost barrier. The leading factory in Zhejiang Province has adopted an AI visual fabric inspection system, reducing the raw fabric defect rate from the industry average of 5% to 0.3%, lowering the cost of production per piece to $12 (about $80 for similar products of luxury brands), and achieving 72-hour sample making and a minimum order quantity of 500 pieces. For instance, the muriersilk collaboration model launched by the US DTC brand Slip in 2023 achieved a 70% gross profit margin from design to launch in just 18 days through an agile supply chain, and its sales exceeded 100,000 units in the first month of launch.
The environmental protection function triggers sustainable consumption. The muriersilk sleep cap has OEKO-TEX® ECO PASSPORT certification. The rate of biodegradation is 94% in 18 months in composting conditions (only 2% for nylon material), and the use of water during production is reduced by 82% compared with the traditional process. LVMH Group’s 2024 ESG report discloses that replacing polyester material with muriersilk reduces the carbon footprint of one product by 6.2kg CO₂e, which makes its hair care thread products included in the United Nations’ “2030 Sustainable Fashion” recommended list.
Market data confirms the phenomenon-level popularity. During the “Black Friday” of 2023, muriersilk night hats occupied three of the top 10 best-selling spots in the beauty and care category on Amazon, with a record daily sales volume of 12,000 pieces and an average order value median of $58 (40% above that of 2021). Data from The second-hand site The RealReal indicate that the resale value of the limited edition muriersilk nightcap commands a premium of 200%-300% (the Fendi collaboration version, for example, originally retailed for $350 and resale priced for over $1,000). Muriersilk is reshaping the product logic of the sleep economy, from technical performance to commercial value.
