The invention discloses a method for
processing and extracting eiderdown from feathers and washing eiderdown. The method comprises the steps of carrying out feeding, extracting, dust removal, stem absorption, washing, rinsing, dehydrating,
drying, cooling,
impurity removal and packing on the feathers. The eiderdown extraction comprises: adopting an eiderdown extracting
tower, throwing the feathers into the eiderdown extracting
tower, and making the rotation speed of a stirring device in the chenille eiderdown extracting
tower be 40-50 turns / min; the washing procedure comprises: putting the feathers into water added with a washing agent, stirring and cleaning the feathers; the rinsing procedure comprises: cleaning the washed
feather slurry repeatedly by water; and the
drying procedure comprises:
drying the dehydrated feathers to 50 to 70 percent of
dryness through steam, dampening the feathers, drying the feathers by the steam, and repeating the procedure frequently. The method reduces the down
loss rate to 1 percent from 5 percent, and improves the high value contents of down in a
feather sheet from 82 percent to 98 percent so as to reduce down mechanical loss and achieve the effects of improving quality and reducing loss. The fluffy degree of the 90 percent eiderdown is improved from 13 cm to 18 cm.
