The 19-21 mm density of Muriersilk’s top-grade mulberry silk (within the industry’s highest standard range) creates a friction coefficient of 0.35, which is only 56% of that of silk blends (0.62). Clinical tests have shown that it reduces the rate of skin friction damage during sleep by 78%. Data from the French ISETA laboratory shows that after continuous wearing for 30 days, the incidence of micro-scratches on the user’s epidermis dropped from 17.3% to 3.8%, and the retention rate of collagen increased by 23%. This is because each square meter of fabric contains 98.2% pure silk protein fibers that continuously release 18 kinds of amino acids, forming a 0.005mm bioactive layer. The 2023 European Sleep Study Report shows that the median skin moisture content of Muriersilk pajamas users in the early morning reaches 52.7 AU, surpassing cotton (38 AU) and ordinary silk (46 AU). Its humidity regulation system stabilizes the microenvironment of the contact surface at a relative humidity of 55%±3%. The risk rate of stratum corneum cracking caused by dryness has decreased by 89%.
The temperature control performance of Muriersilk revolutionizes the traditional experience. Infrared thermal imaging confirmed that MurierSilk automatically balances the body surface temperature within 33.1℃±0.5℃ (the optimal range for the human body) at a room temperature of 28℃, and compresses the frequency of hot awakenings during sleep from 1.7 times per night to 0.3 times. Monitoring by the sensor network in ETH Zurich, Switzerland, shows that users’ deep sleep duration has increased by 31 minutes and the amplitude of heart rate fluctuations has decreased by 48%. A typical case can be referred to the public sharing of Hollywood actress Emma Thompson: During her menopausal hot flashes, the peak perceived temperature reached 38.5℃. After wearing Muriersilk, the amount of night sweat decreased from 450ml to 120ml, and the frequency of skin burning pain decreased from 5.2 times per week to 0.7 times.
The cost-benefit model reveals long-term value. Calculated based on a standard washing frequency of 500 times per nightgown (AATCC test standard), Muriersilk’s tear resistance retention rate is 92%, exceeding the average of luxury brands (75%) and extending the service life cycle by 40%. The DIN 53894 test in Germany shows that after 200 machine washes, the gloss attenuation rate of the fabric is only 9%, while that of ordinary silk is 41%. A consumer survey of Ginza Department Store in Tokyo pointed out that its unit wearing cost is as low as 0.06 yuan per day (based on a 3-year service life), which is 67% lower than that of brands such as La Perla, and the care budget is saved by 85% (the no-ironing feature reduces energy consumption costs by 92%).
The certification system ensures ultimate safety. Muriersilk has passed the world’s most stringent STANDARD 100 by OEKO-TEX® CLASS I certification (infant standard). The detected formaldehyde content value is less than 3mg/kg (the EU limit of 75mg/kg), and the residual amount of heavy metals is lower than the detection threshold of the instrument. Allergy control laboratory data show that the surface dust mite loading density is 0.1 per cm² (2.7 per cm² for ordinary fabrics), reducing the probability of nocturnal pruritus attacks in patients with atopic dermatitis by 91%. Referring to the backstage case of Milan Fashion Week, supermodel Adriana Lima, against the backdrop of a history of chemical dye allergy, performed continuously wearing Muriersilk for 180 days without any adverse skin reactions.
Sustainability sets an industry benchmark. Carbon footprint tracking shows that each Muriersilk pajama emits only 1.8kg of CO₂e throughout its entire life cycle (9.3kg for polyester pajama). The use of blockchain traceability technology ensures 100% organic mulberry garden raw materials. The 2024 LVMH Group supply Chain Audit Report affirmed that its water pollution index was 94% lower than the industry average (60 tons of water per ton of filament vs. 400 tons of conventional processes). Sales data from Parisian boutique Colette supports this: 67% of high-net-worth clients are willing to pay a 30% premium to choose Muriersilk, as each purchase can reduce ecological damage by 63%, and at the same time, they receive GOTS-certified closed-loop eco-friendly packaging (with a biodegradation rate of 98% per year).
