Goose, duck body, neck, tail, wings, tibia, tail hair, processing and disinfection can be made into soft, elastic, thermal and cold-resistant down. So how are feathers collected and processed?
1. Feather and down collection: There are two manual collection methods. One is wet pull. Bleach the slaughtered geese and ducks in hot water at about 70°C for 2-3 minutes, and then pluck them. The water temperature should not be too high, and the immersion time should not be too long to prevent the fluff from protruding and shrinking, and the color is dim. The second is dry pulling. After slaughtering geese and ducks, grab the hair before the body temperature becomes cold to maintain the original color and quality.
2. Cleaning and storage: The collected feathers should be cleaned and disposed of in time, otherwise it is easy to change color, mold or even rot. Cleaning method: Wash the collected wet and dry feathers once or twice with warm water to remove dust, dirt and grime. Then spread it thinly on the mat and let it dry in the sun. To prevent wind blowing, cover it with black cloth or emery cloth. After drying, put it in a fine cloth bag, tie it tightly and store it in a ventilated and dry place for later use.
3. Treatment: Use 60-70℃ soapy water, add a small amount of soda ash for cleaning and degreasing, and then rinse with water. Please note that the water temperature should not be too high or too high. Dry or dry in time after washing. Put the cleaned and defatted feathers in a muslin bag, tie them, put them on the steamer drawer, steam for 30-40 minutes, and then take them out. Steam it again in the same way the next day. Pack the sterilized feathers in a muslin bag and dry.
