We have a professional down processing production base and experience
The main reason for high-quality down is the processing technology after the down is collected. It must be subjected to strict washing treatment. The raw materials of down are washed with detergents and disinfectants in clean water at a certain temperature, repeatedly cleaned, rinsed, dehydrated, and then dried and disinfected by high-temperature steam at 120 ° C for more than 30 minutes. The raw materials can be removed. The ash, feces, blood and oil stains attached to it can achieve the purpose of disinfection and sterilization to remove peculiar smell.
However, if the manufacturer simplifies the washing process in pursuit of low cost, shortens the washing time, does not use clean water sources, uses inferior detergents and disinfectants, or does not control the process parameters in place, and the equipment is not strictly cleaned and disinfected according to regulations, Wet warehouses and poor ventilation conditions will affect the effect of disinfection and sterilization to remove odors, resulting in a strong down smell.
