The present invention can provide a moisture-absorbing and heat-generating feather with high moisture absorption and heat generation and good water repellency, and a feather product using the feather as a filler. According to the manufacturing method of the present invention, a moisture-absorbing and heating-generating feather with high moisture absorption and heat generation and good water repellency can be obtained. According to the feather treatment agent set of the present invention, it is possible to obtain moisture-absorbing and heating-generating feathers with high moisture absorption and heat generation and good water repellency.

The inventors of the present invention have conducted painstaking researches aimed at improving the moisture absorption and heat generation of feathers, enhancing heat preservation, and improving water repellency and preventing cold sweat. As a result, it was found that generally in order to impart a soft texture to man-made fibers, an amino-modified silicone compound is used as a component of a processing agent, and the amino-modified silicone compound is passed through a cationic fixing agent that is usually used as a dye fixing agent. It is fixed on feathers, thereby making the feathers hydrophilic, moisture absorption and heat generation are improved, and water repellency is enhanced, which can prevent cold sweat. Specifically, since the moisture-absorbing and heat-generating feathers of the present invention have high moisture-absorbing and heat-generating properties by absorbing moisture (steam) to generate heat, the moisture generated during the process also increases, but the water repellency is also high. Moisture does not remain inside the feathers, but tends to condense on the surface and drip as water droplets. Therefore, moisture absorption and heat generation can be improved, and cold sweat can also be suppressed.

The feathers are not particularly limited. For example, the feathers of waterfowl such as geese (domestic goose), ducks (domestic duck), wild ducks (wild ducks) that inhabit the coastline of the Arctic Circle, etc. can be used.
