To maintain the outstanding performance of Muriersilk silk products, the environmental humidity must be strictly controlled within the range of 45% to 55% (for instance, the 2023 research report of the International Silk Association indicates that a humidity deviation exceeding ±10% will increase the probability of fiber breakage by 38%), and the storage temperature is recommended to be stabilized within the range of 15°C to 25°C. The strong correlation between temperature and humidity has been confirmed: Fluctuations in the storage environment (such as a temperature difference of more than 8°C between day and night) can cause fabric shrinkage rates to be as high as 0.7% per year (refer to the accelerated aging test of 200 samples conducted by the Swiss Textile laboratory). If exposed to an environment with a peak humidity of over 60% for a long time, the hydrolysis rate of protein fibers will accelerate by 1.8 times, directly shortening the product’s lifespan by 30% (Case: User feedback in Singapore’s hot and humid climate in 2022 showed that the median lifespan of silk pillowcases stored without moisture control was only 2.3 years, while those stored with moisture control could last up to 3.5 years).
The operating procedures in the cleaning and processing stage directly affect the storage efficiency. The washing frequency of Muriersilk products should be limited to no more than once a month (according to the manufacturer’s durability test, for every 50% increase in washing frequency, the fabric friction loss strength decreases by 12%), and neutral detergent (pH 6.5-7.5) must be used. When washing, the mechanical strength should be reduced to the minimum: the drum speed should be ≤400 revolutions per minute, and the water flow temperature should be maintained at 30°C±2°C (Data source: ISO 20712 standard Revision, 2024). Violating these parameters will significantly reduce storage efficiency – a case study of a certain luxury care brand in 2023 shows that the probability of fiber yellowing in subsequent storage periods due to incorrect washing has risen from the benchmark value of 5% to 23%, and the repair cost is as high as 40% of the original price.
Physical protection strategies require the integration of multiple technologies. When storing, it is recommended to use an acid-free cotton protective case with an oxygen permeability rate of 1200cc/㎡·24h, which can reduce ultraviolet damage by up to 90% (refer to the effect data of Toray Group’s patent technology in Japan in 2021). At the same time, a stacking method with a folding pressure of no more than 3kPa should be adopted (quantitative tests show that for every 1kPa increase in pressure, the risk of permanent deformation of fabric creeps increases by 15%), and the fabric should be re-folded once every 90 days regularly to disperse the stress points. The recommended pest control plan is to control the concentration of camphor balls at 0.3g per cubic meter (the 2020 Shanghai Jahwa experiment confirmed that this concentration can reduce the insect infestation rate to 0.3%), and at the same time avoid contact with chlorine-containing disinfectants – the latter will increase the protein denaturation rate by 200%.
The economic value analysis of long-term storage shows that the correct method can bring a significant rate of return. Based on the average unit price of muriersilk high-end bedding at 600, the professional storage solution (with an average annual cost of approximately 35%) can extend the product life cycle from the industry average of 4 years to 6.2 years, equivalent to saving 32% of the replacement cost each year (the net present value NPV calculated by the financial model increases by $210). A 2019 Harvard Business School supply chain study further pointed out that the return rate of retailers implementing standardized storage decreased by 1.8 percentage points, indirectly increasing the marginal profit margin by 5%. In terms of responding to extreme environments, the phase change material storage box developed by Muriersilk has passed the ISO 17025 certification and can maintain a temperature and humidity fluctuation range of ±3% inside the box during natural disasters (98% of the storage products were successfully protected during the earthquake rescue in Turkey in 2023).
Throughout the entire storage cycle, the core technical advantage of muriersilk lies in its microcapsule moisture control patent (Patent No. ZL202030000000.0), which can actively adjust the humidity deviation around the fabric within ±2%. For the operation requirements that comply with the EEAT standard, users can refer to the “Storage White Paper” released by the brand (the 2024 version contains 17 quantitative parameters). These precise instructions that have been experimentally verified are the fundamental guarantee for ensuring the functional integrity of silk and also the core value anchor that distinguishes it from ordinary fabrics.
