How are the duvets we build every day made?

How are the duvets we build every day made? People often say that beauty comes from down jackets, but I don't know if you can't. I couldn't sleep for years anyway. But it is an indisputable fact that down keeps warm. The quality of down is very important to make a good duvet.

First, let's take a look at how down is processed. The raw materials of down mainly come from the feathers of spine or abdomen. Feather is feather and hair is hair, so hair separation is an important link in processing down. First, the recovered feathers are washed with wool to remove foreign matter and dust, and then dehydrated and dried. When the feather is cooled to normal temperature, it can be sucked into the feather separator with a straw for feather separation. The wool separator consists of several boxes, each of which has a different structural design. From front to back, it can be divided into screening and fine sorting.

Secondly, driven by the stirring device and wind power in different boxes, the heavier feather fluff will be precipitated by the bamboo box, and the purest light fluff will be filtered into the last box. Then there is the wool washing tool. After the down is washed by special down cleaner in the washing machine, the oil and smell in it will be removed, and the washed down will be dehydrated again, and then sent to the dryer for drying and sterilization. Fluffy down will be processed here. After the quality inspection, a number of quality tests will be carried out on the down samples. After the fluffy degree is determined to meet the standard, they can be packaged and sent to the bedding processing factory.

Thirdly, after receiving the goods, the factory will check the quality of down again, and after confirming that there is no problem, it can suck down into the down filling device, and then the workers will insert the down filling tube into the lattice interlayer of each quilt to fill the down in a relative proportion. When filling cotton, the wind of the cotton filling pipe will also beat the down in the grid at the same time. Send the filled quilt to the sewing workshop for sewing, and then enter the final drilling ability test. After it is confirmed to be qualified, it can be packaged and put into storage.
