Problems solved by technology

[0002] At present, the down on the market does not have a waterproof function. The washing technology of the down processing factory is only for cleaning and disinfection, so the processing process is: washing-dehydration-steam drying at high temperature, but the waterproofing process requires the use of nano-waterproofing agents. The molecule itself is smaller than water. If the agent is added according to the ordinary washing method, the originally wet down will not be able to absorb the agent, resulting in failure of the waterproof effect. Therefore, it is necessary to overcome technical difficulties in processing waterproof down. At present, there are few reports on related technologies in this regard.

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.

Abstract

The invention provides a waterproof down manufacturing method. The waterproof down manufacturing method comprises the following steps of preparing washing agents and waterproof agents; washing the down in the washing agents; dehydrating the washed down and drying the down at a high temperature until the down contains no moisture; putting the dried down into a refrigerated air dryer, spraying the waterproof agents, stirring the down to enable the agents to fully cover the down, and meanwhile leading normal temperature wind to blow-dry the down; placing the down into a steam high temperature dryer for being dried to a water-free state. The waterproof down manufacturing method overcomes the technical difficulty that molecules of nano waterproof agents are relatively small and hard to absorb, the manufactured down does not carry foul smells and is clean and hygiene due to a waterproof function. After high temperature sterilization, the down does not carry germs. Besides, the waterproof down manufacturing method is simple, easy to achieve and low in production costs.

Description

technical field [0001] The invention relates to the field of waterproof down, in particular to a method for making waterproof down. Background technique [0002] At present, the down on the market does not have a waterproof function. The washing technology of the down processing factory is only for cleaning and disinfection, so the processing process is: washing-dehydration-steam drying at high temperature, but the waterproofing process requires the use of nano-waterproofing agents. The molecule itself is smaller than water. If the chemical is added according to the ordinary washing method, the originally wet down will not be able to absorb the chemical, resulting in the failure of the waterproof effect. Therefore, it is necessary to overcome technical difficulties in processing waterproof down. At present, there are few reports on related technologies in this regard. Contents of the invention [0003] In order to solve the problems existing in the prior art, the invention...
