[0035] Example 1
[0036] The washing down processing method includes the following steps:
[0037] 1) Material selection, pre-sorting and ash removal of down, so that the ash content of down is less than 5%;
[0038] 2) Washing: Pre-wash at 30°C for 2 hours, wash at 50°C for 1 hour, and rinse at 40°C for 2 hours;
[0039] Add 2.3% detergent when washing; add 1.2% hydrogen peroxide and then 2% glacial acetic acid when rinsing;
[0040] In parts by weight, the detergent contains the following ingredients: 2.3 parts stearyl alcohol polyoxyethylene ether, 1.2 parts hydroxypropyl methylcellulose, 1.2 parts dodecyltrimethylammonium sulfate, 1.2 parts polyoxyethylene Glycerol monostearate, 2.3 parts of maleic anhydride modified polyethylene, 3.4 parts of polyvinylpyrrolidone, 2.3 parts of vinyl trimethoxysilane, 1.2 parts of polyoxyethylene rosin acid;
[0041] 3) Dehydrate, make the down moisture content 20%;
[0042] 4) Drying and cooling.
