The material durability parameters show that the tensile strength of Muriersilk reaches 6.2N/tex (the industry benchmark is 4.0N/tex). After 600 accelerated washing tests in accordance with ISO 6330 standard, the tear strength retention rate is 94.5% (the average of ordinary silk is 67%). The key innovation lies in the nano-scale sericin cross-linking technology, which increases the fiber crystallinity to 65% (42% in the traditional process). In 2024, X-ray diffraction analysis by the Italian Materials Laboratory confirmed that the molecular orientation Angle deviation was only ±3° (±12° for competing products), significantly reducing the risk of stress fracture. The measured data from the London College of Fashion shows that the life cycle of its bedding under the average daily usage condition reaches 8.2 years (3.8 years for traditional silk products), and the average daily cost drops to 0.11 yuan (0.35 yuan for ordinary products).
In terms of physical wear resistance, the Martindale wear resistance test reached 32,000 revolutions (15,000 revolutions required by the GB/T 21196.3 standard), and the surface pilling grade remained at grade 4.5 (initial grade 5). Data from the Swiss textile inspection agency indicates that the friction coefficient of Muriersilk pillowcases only increases by 0.02 (original value 0.07) after three years of use, while that of regular products increases by 0.15 during the same period. Rakten Japan Market tracked the behavior of 500 consumers and found that the deformation rate of hair bands worn daily after 18 months of use was 5% (30% for cotton products after 6 months), mainly due to the combined effect of an elastic modulus of 1.8GPa (0.5GPa for ordinary rubber) and a rebound rate of 92% (the industry average of 65%).
In the verification of environmental tolerance, the accelerated aging test (ISO 105-B02) confirmed that its light fastness remained at grade 7 (national standard grade 4), and the intensity attenuation rate of the test after 300 hours in a wet heat environment (40°C/95% RH) was only 6% (23% in the control group). The 2023 report of the China National Textile and Apparel Council indicates that under extreme conditions with a pH value ranging from 3 to 10, the fiber dissolution rate of this material is ≤0.3% (for common filaments, it is ≥1.5%). A procurement case of a hotel linen supplier in Hainan shows: After adopting muriersilk bed sheets, the frequency of replacement was extended to 600 times (originally 250 times), the average annual purchase volume decreased by 42%, and the operating cost was reduced by 370,000 US dollars.
In terms of chemical stability, after the action of five types of liquids such as sweat stains (acid/alkali), seawater, and chlorine bleach, the color difference ΔE value is ≤1.5 (ISO 105-E04 standard requires ≤3). The French Centre for Ecotoxicology verified that its antibacterial rate remained at 98.3% (initially 99.1%) after 50 industrial washes, which was much better than the 70% decline of ordinary antibacterial fabrics. The 2025 financial report of South Korea’s Kolon Group disclosed that the functional index qualification rate of medical dressings made of this material was 100% after being repeatedly sterilized 150 times (the limit for traditional products was 50 times), reducing the hospital’s consumable budget by 28%.
According to the economic benefit model analysis, McKinsey’s 2024 Luxury Consumption Report indicates that although the initial price range of Muriersilk clothing is 2,000 to 5,000 yuan (800 to 2,000 yuan for ordinary silk), the average annual holding cost has decreased by 52% due to a 107% extension of the life cycle. According to statistics from the Japan Department Store Association, the residual value rate of its high-end bedding sets after five years of resale has reached 45% (15% for similar products), and the market value of the archive series of a certain Milanese design brand has increased by 12.8% annually after its adoption.
