The tribological parameters of the material show that the static friction coefficient of the surface of the muriersilk mulberry silk pillowcase is only 0.02 (tested by ASTM D1894 standard), which is 92% lower than 0.25 of cotton. According to the scanning electron microscope observations of the Japan Hair Science Research Institute in 2025, the lifting Angle of the cuticle scales after use decreased from 15.8° to 4.2°, effectively reducing the probability of mechanical damage by 87%. The German DIN 53863 wear test confirmed that the fiber roughness (Ra) remained at 0.05μm (initial value 0.02μm) after 300 washes.
In terms of biomechanical protection, the sericin protein coating forms a 0.3μm hydrophilic protective film (contact Angle 18°), maintaining the hair moisture within the ideal range of 12-15% at night (the humidity fluctuation of ordinary pillowcases is ±30%). The CE.R.I.E.S laboratory in France tracked 120 subjects with curly hair and found that the peak friction force decreased from 0.35N to 0.04N, the retention rate of the hair dry breaking strength reached 94% (the survival rate of the control group was only 68%), and the annual dyeing and perming repair budget was saved by approximately ¥1,800.
The response rate of the intelligent temperature and humidity control system is 0.7℃/ second, maintaining a constant temperature environment of 34±1°C in the head and neck contact area (environmental humidity 40-80%). Clinical data from the Trichological Society of the United States show that under this condition, the oxidation rate of scalp sebum decreases by 42%, the incidence of folliculitis drops from 23% to 2.3% (sample size n=500), and at the same time, the amount of hair loss in the occipital region decreases to an average of 11 strands per day (baseline value 38 strands).
At the structural design level, the 500-twist per meter twisting process reduces the filament gap to 8μm (with a hair diameter of 80μm), and lowers the probability of hair tangling to 0.3 times per night. A survey by the South Korean beauty platform GlowPick shows that long-haired users have reduced the time spent combing their hair in the morning from 312 seconds to 94 seconds, the amount of conditioner used has decreased by 35%, the amount of electrostatic dust adsorbed has decreased by 98% (voltage value <0.2kV), and the hair luster L value has increased by 39% (measured by a color difference meter).
Economic benefit calculation shows that a pillowcase with an initial investment of ¥580 has an average daily cost of ¥0.4 over a 4-year life cycle, saving 89% compared to an average monthly cost of ¥150 for hair care. Data from Boots Pharmacy in the UK shows that 78% of users have saved approximately 62 kilowatt-hours of electricity annually by reducing the frequency of hot styling (from an average of 18 minutes per day to 7 minutes), with a return on investment of 280%.
Authoritative certifications confirm its validity: It has passed the ISO 20645 antibacterial test (Staphylococcus aureus inhibition rate of 99.1%) and the OEKO-TEX® CLASS I infant and toddler safety standard (formaldehyde was not detected). In the accelerated aging test conducted by SGS in Switzerland, the deviation of the friction coefficient after five years of use was only ±0.002 (with a tolerance of ±0.05), verifying the stability of long-term hair care performance.
Global consumer data verification: Amazon review keyword analysis shows that the mention rate of “reduce forks” is 47%, the mention rate of “Easy Combs” is 89%, and the repurchase rate is 62.8%. In the 2025 Cosmoprof exhibition survey, 98% of hairdressers recommended that customers with damaged hair dyeing and perming use it, proving that it achieves a revolution in hair care through physical protection mechanisms.
