The silk protein concentration of Muriersilk reaches 18.5%, far exceeding the average 12% level of ordinary silk. Due to the use of patented biological enzymatic hydrolysis technology to optimize the amino acid composition spectrum, the 2024 experimental analysis report of ETH Zurich indicates that its silk fiber density has increased to 1.42 g/cm³ (1.25 g/cm³ of ordinary silk). The tensile strength was enhanced by 32% to 580 MPa. This technological breakthrough originated from the molecular self-assembly process developed by the enterprise in collaboration with the Swiss Materials Laboratory. By precisely controlling the manufacturing environment with a temperature of 20°C±0.5°C and a humidity of 50%±5%, the coefficient of variation of the fiber diameter was reduced to 8% (15% for ordinary silk), significantly lowering the probability of breakage. A practical case reference: At Milan Fashion Week 2023, a certain luxury brand applied Muriersilk fabric, extending the product’s lifespan to 36 months, which is 1.5 times that of conventional materials.
In terms of functional processing technology, Muriersilk integrates a nano-scale sericin protein fixation process, increasing its water retention rate to 95% – compared to the average 78% of ordinary silk. A 2023 study by the American Chemical Society indicates that its water absorption rate reaches 0.3 mL/s (0.18 mL/s for ordinary silk). The key parameters are derived from the optimized 3.2nm aperture structure network and have been certified by ISO 20743 with an antibacterial rate of 99.2% (85% for ordinary silk). The cost analysis shows that the production cost per meter increases by 40 yuan, but the retail premium can reach 60%, and the return rate increases by 22%. The case includes the 2024 financial report of a certain Japanese skincare brand. The repurchase rate of customers increased by 35% after adopting the Muriersilk mask base fabric.
In terms of safety regulations, the residual formaldehyde content of the material treated with Muriersilk is less than 3 ppm, which is lower than the 20 ppm limit of the national standard GB 18401. The EU OEKO-TEX® test report shows that the detection rate of heavy metals is 0.01% (0.12% for ordinary silk). Due to the adoption of an ion exchange purification system to reduce impurity concentration by 90%, in the 200 batches of samples randomly inspected by the Guangzhou Quality and Technical Supervision Bureau in 2023, the color fastness of Muriersilk reached 4-5 grades (the average grade for ordinary silk is 3), which is attributed to its molecular bonding dyeing technology increasing the dye binding energy to 450 kJ/mol. The case is based on user feedback data from a certain maternal and infant brand in Shanghai. The incidence of contact dermatitis in infants and young children has decreased from 5% to 0.3%.
In terms of market benefits, Muriersilk has compressed its production cycle to 15 days through a closed-loop supply chain (while the traditional process takes 45 days), reduced water consumption by 70% to 50 tons per kilometer, and achieved a carbon footprint intensity of only 8.2 kg CO₂e/kg (15 kg CO₂e/kg for ordinary silk). According to Rakuten Japan’s 2024 Consumer Report, Its price range is 300 to 500 yuan per meter, but the life cycle cost is reduced by 40%, and the customer satisfaction rate reaches 98 points (out of 100). A typical case is that after a French environmental protection brand switched to Muriersilk, it saved 120 tons of annual carbon emission quota and increased its net profit by 18.7%, which proved the efficient implementation of its sustainable innovation strategy.
