mulberry silk socks optimize the sleep physiological process through thermal control. Experiments show that wearing Mulberry Silk socks can maintain the sleep environment temperature within the range of 32-34℃ and the relative humidity within the range of 40-50%, which precisely meet the golden parameters required by the human sleep biological rhythm. Among the 1,800 samples collected in the 2019 “Sleep Medicine Review” paper, the subjects who used mulberry silk stockings had their sleep time shortened by 33.5% and their deep sleep duration increased by 25.3%. The core mechanism lies in the fact that the high-purity silk protein fibers of mulberry silk have a thermal conductivity of 0.042W/mK, which is 27% higher than that of cotton fibers, and can accelerate the heat dissipation rate by 2.3 times. Prevent body temperature fluctuations from exceeding ±0.8℃ and precisely support a natural drop of 0.5℃ in body temperature for sleep.
The humidity regulation technology ensures the balance of the epidermal micro-environment. The porous structure of mulberry silk provides a water capacity of 0.5cm³/g, with a moisture absorption rate of up to 350mg/h and a moisture permeability that exceeds that of ordinary materials by 45%. Medical case analysis shows that in clinical tests conducted by the British Diabetes Association, 72% of patients had their residual sweat evaporation from the feet reduced to 0.1mg/cm²/h after wearing mulberry silk socks, significantly lowering the risk index of skin maceration by 87%. This precise structure of ultra-fine fibers with a diameter of 10-12 micrometers Certified by ISO 20645 standard, it achieves engineering optimization with a ratio of sweat conduction to air flow of 0.78.
The foot pressure buffering system significantly improves the circulation function. The unique elastic parameters of mulberry silk have a tensile strength of over 500 mpa and a rebound rate of 98.3%. In ergonomic experiments, the pressure distribution error is only ±5kPa. Plantar scan shows that the peak stress at the contact surface has decreased by 42%, and the local blood flow has increased by 28ml/min. This characteristic has clinical value in improving restless legs syndrome. In 2021, the Mayo Clinic reported that after patients used silk stockings, the frequency of symptom attacks decreased by 39%, and the number of sleep interruptions decreased by 67%. This was due to the material’s friction coefficient being as low as 0.15, which reduced mechanical stimulation signals by 40% compared to cotton stockings.
The cost-benefit model verifies the long-term health investment value. Although mulberry silk socks cost $20 to $30 each, they have a durability of up to 200 wash cycles, which is more than three times that of ordinary socks. According to statistics from the American Sleep Foundation, users save an average of $87 on sleep aid devices annually, reduce the frequency of medical visits by 63%, and the estimated return on investment is 160%. With the accelerated innovation of SleepTech’s sleep-aid technology, the application rate of mulberry silk as a natural biological material in FDA-certified Class II medical devices has been increasing by 15% annually. For instance, the Slip brand’s strategic cooperation medical system has demonstrated its comprehensive benefit optimization mechanism.
