Description

Device and method for preparing pile core wire Technical Field The invention relates to a device and a method for preparing a pile core wire, belonging to the technical field of textile. Background The down feather is soft down feather covered by the body surface of waterfowl animals (such as duck, goose, etc.), and is mainly distributed on chest and abdomen. The three-dimensional structure of the velvet flowers can lock a large amount of static air to form a high-efficiency heat insulation layer, and the heat insulation capacity per unit weight is far higher than that of the artificial material. The fluffy structure makes its density extremely low, and weight is obviously lighter than cotton or chemical fiber filler under the same effect of keeping warm. The microporous structure between the fibers can adjust the humidity, not only can block cold air, but also can discharge body surface moisture, and is comfortable and dry. Can be folded and stored after being pressed, and can rebound rapidly to restore the original fluffy state after being released, thereby being convenient to carry and store. The down is a natural material with light weight, warm keeping and durability by virtue of the unique biological structure. However, the down has smooth surface and small friction coefficient, and is easy to fall off during spinning, so that the down is only used as a filler in the market, and the cold-proof and warm-keeping effects are applied to the field of spinning.
