Duvet - the lightest quilt
Duvets are mainly stuffed with goose down and duck down. In contrast, goose down is compared
The duck down is better. But no matter which duvet, its main quality index is the amount of cashmere. Generally speaking, the high quality duvets are 50% of the wool.
The duvet is selected by the core type.
Duvet is core with white goose down, grey goose down, duck down, grey duck down, geese and ducks mixed wool and wool etc, downcontent respectively in 15 ° 70 creates between. The best quality is goose down, which is large, small and small, with good quality, elastic foot and good heat preservation. The second is duck down, which is inferior to goose down, but the quality, flexibility and warmth are high. The goose duck mixes the flannelette to the general, the flexibility is poor, but the warm sex is also good, and the pulverized velvet because it is the wool sheet processing pulverization, the elastic force and the warmth difference, has the powder, the quality is more. Feather is a kind of animal protein fiber, is higher than cotton (plant fiber), heat preservation, and feather ball fiber in the thousands of tiny pores, triangle can change with the temperature expansion and contraction, temperature adjustment function, can absorb the human body is sending out flow of heat, isolated from the outside cold air invasion.
The health function of the duvet is determined by the unique soft warmth and the good performance of the absorbent. From warm degree, scientific research institutions in France released into the results that the world does not have any heat preservation material than down heat preservation performance, because feather is star structure, each hair silk all can be seen under the magnifying glass is designed, there are thousands of tiny pore, reservation is with a lot of still air, due to the air of the lowest conduction coefficient, formed the feather good warmth retention property, and feather and full of elasticity, 50 for HanRongLv feather hair test, its light volume is equivalent to 2.5 times of cotton, wool, 2.2 times, duvets so not only soft and warm, and touch the skin feeling is very good also, in addition, the feather hair also has other heat preservation material does not have the good performance of the moisture absorption of divergence. , according to the determination of people during sleep the body continuously spread outward khan gas, an adult night sweat emitted about 100 grams left and right sides, feather can warm constantly release sweat absorption and emission, make the body without the damp and hot feeling. To sum up, because the peculiar to the feather hair soft and warm, the good performance of hygroscopic divergent, so I sleep will feel warm and comfortable, duvet cover and oppressive feeling, make the blood pressure is normal, central nervous to stability, enter sweet dreamland quickly, it also has a great effect on beauty, "beauty" under the duvet just because of this reason. Advantages: good heat preservation, good moisture absorption, perspiration and dry. To adapt to the crowd: for duvet also has the characteristics of light, soft, soft, and its weight, much lighter than the quilt, etc, when using won't cause pressure on the human body, so is suitable for people with high blood pressure, heart disease, poor circulation, and the elderly, pregnant women, children, etc.
The downsides: the duvet is broken off by tiny villi, which permeates the room and enters the throat.

The lungs, the cough, the lungs. In order to prevent the phenomenon of drilling pile is commonly used coating high-density fabric quilt cover, this kind of fabric is chemical fiber fabrics, more in the winter using electrostatic phenomenon is serious, good to the skin and stimulates the pore, poor comfort; The feather absorbs heat speed relatively fast, the heat release speed is also relatively fast, after midnight easy to feel the whole body hair cold; During temperature rise and also will produce a large number of static electricity, to stimulate the skin, the skin coarse, stimulate nerves, to produce more dream, serious impact on health, and bug eat by moth and mildew resistance is poor, the need to use when stored in pest control.
