Embodiment 1
[0019] The preparation method of waterproof eider down of the present invention, it comprises the steps:
[0020] 1. Prepare washing agent and nano-waterproofing agent so that the mass concentration of nano-waterproofing agent is 7%.
[0021] 2. Put the down in the washing device, add washing agent for washing.
[0022] 3. After dehydrating the washed down with a centrifuge, put it in a high-temperature steam dryer with a temperature of 90 degrees Celsius and dry it at a high temperature until it does not contain moisture.
[0023] 4. Place the dried down in a cold dryer, spray nano-waterproof agent, the mass ratio of it to down is 60~70:100, stir to make the nano-waterproof agent fully cover the down, and introduce normal temperature wind to blow the down Dry.
[0024] 5. Dry the down in a high-temperature steam dryer at a temperature of 90 degrees Celsius until there is no moisture.
Embodiment 2
[0026] The preparation method of waterproof eider down of the present invention, it comprises the steps:
[0027] 1. Prepare washing agent and nano-waterproofing agent so that the mass concentration of nano-waterproofing agent is 6%
[0028] 2. Put down and down in the device, and add washing agent for washing at the same time.
[0029] 3. After the washed down is dehydrated with a centrifuge, it is placed in a high-temperature steam dryer at a temperature of 95 degrees Celsius and dried at a high temperature until it does not contain moisture.
[0030] 4. Place the dried eider down in a cold drying machine, spray nano-waterproof agent, the mass ratio of it to eider down is 60~70:100, stir to make the nano-waterproof agent fully cover the eiderdown, and at the same time, introduce normal temperature wind to blow the eider down blow dry.
[0031] 5. Dry the down in a high-temperature steam dryer at a temperature of 95 degrees Celsius until there is no moisture.
Embodiment 3
[0033] The preparation method of waterproof eider down of the present invention, it comprises the steps:
[0034] 1. Prepare washing agent and nano-waterproofing agent so that the mass concentration of nano-waterproofing agent is 8%
[0035] 2. Put the down in the washing device, and add washing agent to wash it.
[0036] 3. After dehydrating the washed down with a centrifuge, put it in a high-temperature steam dryer with a temperature of 85 degrees Celsius and dry it at a high temperature until it does not contain moisture.
[0037] 4. Place the dried down in a cold dryer, spray nano-waterproof agent, the mass ratio of it to down is 60~70:100, stir to make the nano-waterproof agent fully cover the down, and introduce normal temperature wind to blow the down Dry.
[0038] 5. Dry the down in a high-temperature steam dryer with a temperature of 85 degrees Celsius until there is no moisture.
