Goose Feather Thermal Insulation Special

Goose Feather is a special derivative of avian skin, which plays a protective role. According to its structure generally divided into 3 kinds: positive feather, velvet feather, fiber feather. Is feather is the most conspicuous feather, mature feather is divided into flying feather-it includes wings-dead Shanyu and aileron, tail feathers, body plume long in the trunk, neck, legs and other parts. The shape of the positive feather is in the middle of a feather sleeve, the next paragraph is called the plume Root, buried in the skin of the SAC, Goose Feather the upper section is the feather stalk, the stem feather piece, the feather piece is composed by many parallel feather branches, the feather branch also has two rows of small feather branches, the small feather branch has the small fishing, the mutual hook weaves together to form the feather piece. Velvet Feather has no feather axis, only a very short and thin feather stems, feather branches longer, small feather technology is not small hook, Goose Feather so like a hair core radiation thread thin velvet, a blossoming, also known as Velvet Flower. In the goose body close to each positive feather Mao Jian has a fine velvet feather, it grows in the goose body Feather's inner layer, clings to the skin, plays the heat insulation function. Fiber plume is a single existence of thread feather branches, characterized by the soft and long, mainly in the inner layer of the feather in the place.

The composition of goose feathers accounted for 89%-97% of the protein, it can be said that goose feathers are composed of proteins, in the composition of the goose feather protein accounted for about 85%-90%. The protein is initially synthesized with the formation of a follicle and keratin. Goose feathers are derived from the skin, Goose Feather forming a hair follicle first, producing a plume, feather root end and dermis form goose feather nipple, blood vessel thus enter feather pith, feather stuffing has rich blood vessel and full of gelatin-like material, goose feather in the growth process need nutrition, through the feather blood supply, feather lang along with goose feather grow and extend. After the goose feathers mature, the blood vessel starts to atrophy from the upper part of Goose feather, degenerates, gradually the movement shrinks to the feather root. Goose feathers are not mature, the plume is filled with blood vessels in the plume, red, commonly known as capillary hair. The feather is white because of the atrophy of blood vessels after mature goose feathers.

Goose feathers in the fertilized eggs hatch to the 10th day can be used magnifying glass to see the base of goose feathers throughout the body part, paras days all the trunk has fluff, the 17th day of the whole body has fluff, in the next 13 large villi continue to grow mature, Goose Feather out of the shell of the young Goose a golden fuzz, have very fine feather stems, the top only a few small feather branches, weight is very light, but warm sex is very good. The growth regularity of goose feathers in goose stage due to the different breeds of goose, the age of the 1th time change is slightly different, for example, Lakiang is too hybrid goose, the "Fin" day age is about 55-60 days.

The change process of goose feather is influenced by heredity, environment and nutrition condition, and the content of protein in feed directly affects the growth and replacement of goose feather. In particular, the amount of sulfur-containing amino acids in feed directly affects the growth and development of goose feathers. Because the synthetic keratin mainly relies on the sulfur-containing amino acid, Goose Feather namely the glycine and the methionine. Niacin is the main ingredient of keratin. Can directly participate in the synthesis of keratin. Methionine is involved in the synthesis of keratin by converting to a clean ammonia acid. During the growth of goose feather, it should account for about 54% of the total flow of amino acid. The demand of the niacin can be decreased when goose feather grows mature.

The growth and development of goose feather is carried out along with the growth and metabolism of the whole organism, so it is necessary to consider not only the nutritional needs of goose feathers, but also the nutritional needs of the whole organism. In the lack of nutrition, goose feather growth is slow, Goose Feather but priority in the growth of the muscle just fat, the past rural habits of feeding method hanging shelves, the formation of the Rack goose body hair, but no meat on the body, before the listing must be bred friends, this method is not advisable. The growth of goose feathers is normal, can be used to check the management measures are reasonable, so the masses are very attached.

Goose feather can be divided into big tail feathers, large wing feather, chest, back, body side, tail, neck of the piece feather and Velvet feather, etc. 4 kinds. After the above-mentioned cleansing, the goose feather can be packed separately according to its classification. You should also pay attention to "flying silk" and "blackheads" when loading. "Flying silk" refers to the feather and feather feathers off the broken feather silk, the main house when the operation is improper and produced. "Black" WU refers to different color plush. Goose Feather Goose feathers to the mouth, "flying silk" content should not exceed 10%, "blackheads" the amount of not more than 2%. Therefore, the separation of goose feather should be as far as possible to remove "flying silk" and "black".

The initial processing of goose feathers refers to the process of cleaning, classifying and packaging goose feathers. First, the goose feather into the bucket containing $number caustic soda solution of immersion, the next day to stir cleaning, with the washing with water, to remove the goose feathers on the grease, blood and dust. The marsh is cleaned and dried or dried, and sorted and packaged.
